| At any
        time after the judgment of dissolution, the court upon motion of either
        party may modify the spousal maintenance or child support
        provisions.  generally, modification may be granted only where
        there has been a substantial material change in circumstances occurring
        subsequent to the original court order.  The change usually must be
        more or less permanent rather than temporary.  With respect to
        child support, a material change of circumstances will be presumed by
        the court if support as calculated by the guidelines is an appropriate
        or significant amount. each state has some particular concerns and
        requirements; therefore, an attorney in your particular state should be
        consulted. 
 Please see specific state for details and/or
        differences.

 ALABAMAA prior child support award may be modified only on proof of changed
        circumstances, and the burden is on the party seeking the modification. The moving
        party must show a substantial and continuing material change of circumstances. 
        Alabama Code 30-3-1.
 The child support guidelines shall be used by the parties as the basis for periodic
        updates of child support obligations. There shall be a rebuttal presumption that child
        support should be modified when the difference between the existing child support
        award and the amount determined by application of the guidelines varies more that 10%, unless the variation is due to the fact that the existing child support award
        resulted from a rebuttal of the guidelines and there has been no change in the
        circumstances that resulted in that rebuttal of the guidelines.
 Rule 32, Alabama Rules of Judicial Administration.
 The alimony provisions in a divorce decree can be modified upon the showing of
        a material change in circumstances. The focus is on whether there has been a material
        change in the financial or economic needs of the payee spouse and the ability of the
        payor spouse to respond to those needs.  Alabama Code 30-2-51.
 If a spouse who is receiving alimony remarries or is living openly or cohabiting
        with a member of the opposite sex, the court shall modify a divorce decree to terminate
        alimony.
 Alabama Code 30-2-55.
 ALASKAAt any time after the Judgment of Dissolution, the court, upon motion of either party,
        may modify the spousal maintenance or child support provisions. Generally, modification
        may be granted only where there has been a substantial material change in
        circumstances occurring subsequent to the original court order. The
        change usually must be more or less permanent rather than temporary. With respect to child support, a
        material change of circumstances will be presumed by the court if support as calculated
        by the guidelines is more than 15% greater or less than the prior support order. 
        AS 25.24.170 and Rule 90.3, Alaska Rules of Court.
 ARIZONAThe child support and spousal maintenance provisions of a Decree of Dissolution
        may be modified only as to installments accruing subsequent to notice of the Motion for
        Modification to the opposing party and only upon a showing of changed circumstances
        which are substantial and continuing. The provisions in a Decree for Property
        Disposition may not be revoked or modified unless the court finds existence of conditions
        that justify the reopening of a judgment under the laws of Arizona.
 Unless otherwise agreed in writing or expressly provided in the Decree, the
        obligation to pay future spousal maintenance is terminated upon the death of either party
        or the remarriage of the party receiving maintenance.
 Unless otherwise agreed in writing or expressly provided in the Decree,
        provisions for the support of a minor child are not terminated by the death of a parent
        obligated to support the child. When a parent obligated to pay support dies, the amount
        of future support may be modified, revoked or commuted to a lump sum payment to the
        extent just and appropriate in the circumstances.  ARS �25-327.
 ARKANSASThe alimony and child support provisions of a divorce decree are always subject
        to modification, by application of either party, upon a showing of a change in
        circumstances. With respect to child support, the court may not modify the provisions in
        the decree prior to the filing of a motion for modifications. However, the court may offset
        against future support to be paid with those amounts accruing during time periods, other
        than reasonable visitation, in which the non-custodial parent had physical custody of the
        child with the knowledge and consent of the custodial parent.  Ark. stat. Ann. 9-12-314.
 CALIFORNIAA child support or spousal support order may be modified or terminated at any
        time as the court determines to be necessary. This applies whether or not the support
        order is based upon an agreement between the parties. An order for spousal support
        may not be modified or terminated to the extent that a written agreement, or an oral
        agreement in open court between the parties, specifically provides that the spousal
        support is not subject to modification or termination. The primary issue is whether there
        has been a substantial change in circumstances since the decree or last court order. 
        Cal. Fam. Code �3651.
 California law provides for inexpensive discovery of facts before asking the court
        to modify or terminate an order for child support or spousal support. At any time
        following a judgment of dissolution of marriage, either party, without leave of court, may
        serve a request for the production of a completed current income and expense
        declaration in the form suggested by the Family Law Rules. This simplified request for
        discovery may be undertaken not more frequently than once every 12 months, unless
        there is a pending motion for modification. A copy of the prior year�s tax returns shall be
        attached to the income and expense declaration of each party.
 Cal. Fam. Code �3660-3668.
 In determining a motion for modification of child support, the court shall not
        consider the income of the obligor parent�s subsequent spouse or non-marital partner,
        except in an extraordinary case where excluding that income would lead to extreme and
        severe hardship to any child subject to the child support award. An extraordinary case
        may include a parent voluntarily or intentionally quitting work or reducing income.
 Cal. Fam. Code �4057.5
 In the case of a motion for modification of an award of spousal support, there is a
        rebuttable presumption of decreased need for spousal support if the supported party is
        cohabiting with a person of the opposite sex. The income of a supporting spouse�s
        subsequent spouse or non-marital partner shall not be considered when modifying
        spousal support.
 Cal. Fam. Code �4323.
 COLORADOThe spousal maintenance provisions of a decree may be modified upon a
        showing of changed circumstances so substantial and continuing as to make the terms
        unfair. The child support provisions of a decree may be modified only upon a showing of
        changed circumstances that are substantial and continuing or on the ground that the
        order does not contain a provision regarding medical support, such as insurance
        coverage, payment for medical insurance deductibles and co-payments, or
        un-reimbursed
        medical expenses. The provisions as to property disposition may not be revoked or
        modified unless the court finds the existence of conditions that justify the reopening of a
        judgment.
 If spousal maintenance or child support is modified by the court after the decree,
        the modification should be effective as of the date of the filing of the motion by the
        requesting party, unless the court finds that it would cause undue hardship or substantial
        injustice. In no instance shall the modification be retroactive prior to the date of filing.
 Colorado law provides for a simplified procedure to modify a child support order
        when both parties agree to the modification and do not require a court hearing. When a
        voluntary change of physical custody occurs, the provisions for child support will be
        modified as of the date when physical custody was changed. When there is a voluntary
        change of physical custody, the parties are encouraged to use the statutory provision for
        updating and modifying a child support order without a court hearing.
 CRSA �14-10-122 and 14-10-115(3)(b).
 CONNECTICUTUnless the decree precludes modification, the court may modify any order for
        alimony or child support upon a showing of a substantial change in the circumstances of
        either party. The current child support guidelines can be considered unless there was a
        specific finding in the decree that the application of the guidelines would be inequitable
        or inappropriate. There shall be a rebuttable presumption that there is a substantial
        change of circumstances if application of the child support guidelines would result in
        increasing child support by 15% or more.
 The court may modify the award of alimony in a decree and suspend, reduce, or
        terminate the payment of alimony upon a showing that the party receiving the alimony is
        living with another person under circumstances which the court finds should result in
        modification because the living arrangements cause such a change of circumstances as
        to alter the financial needs of that party.  C.G.S.A �46b-86.
 DELAWAREThe child support and alimony provisions of a decree may be modified or
        terminated upon a showing of real and substantial change of circumstances. Unless the
        parties agree otherwise in writing, the obligation to pay future alimony is terminated upon
        the death of either party or the remarriage or cohabitation of the party receiving alimony.
        Cohabitation means regularly residing with an adult of the same or opposite sex, if the
        parties hold themselves out as a couple, and regardless of whether the relationship
        confers a financial benefit on the party receiving alimony. Proof of sexual relations is
        admissible but not required to prove cohabitation. A party receiving alimony shall
        promptly notify the other party of his or her remarriage or cohabitation.
 13 DCA �1512 and 1519.
 FLORIDAThe court retains jurisdiction to make orders, as equity requires, to decrease,
        increase, or confirm the amount of child support or alimony provided for in the judgment
        or prior court order. The primary issue is whether there is a substantial change in the
        circumstances of the parties. Application of the child support guidelines may provide the
        basis for proving a substantial change in circumstances. However, the difference
        between the existing child support order and the amount required by the guidelines must
        be at least 15% or $50, whichever amount is greater, before the court may find a
        substantial change in circumstances.
 FSA Stat. �61.14 and 61.30.
 GEORGIAThe alimony provisions in a Decree shall be subject to modification upon a
        Petition filed by either spouse showing a change in the income and financial status of
        either former spouse. No Petition for Modification may be filed by either former spouse
        within a period of two years from the date of the final order on a previous Petition by the
        same former spouse. After hearing both parties and the evidence, the jury, or the judge
        if a jury is not demanded by either party, may modify and revise the previous judgment in
        accordance with the changed income and financial status of either party. The voluntary
        cohabitation of a former spouse with a third party shall be grounds to modify the
        provisions for periodic payments of permanent alimony for the support of that spouse.
 The child support provisions of the divorce decree or prior court order shall be
        subject to modification upon Petition filed by either former spouse showing a change in
        the income and financial status of either former spouse or in the needs of the children.
        No Petition may be filed by either former spouse within a period of two years from the
        date of the final order on a previous Petition by the same former spouse. After hearing
        both parties and the evidence, the jury, or the court where a jury is not demanded by
        either party, may modify the previous judgment in accordance with the changed income
        and financial status of either former spouse or in the needs of the children. Child support
        may be modified pursuant to the child support guidelines only after the Petitioner first
        makes a showing that there has been a significant change of material circumstances
        since the time of the decree or prior order.
 GC �19-6-15 and 19-6-19.
 HAWAIIThe court may modify child support orders upon a showing of a change in the
        circumstances of either party or any child since the entry of any prior decree or order for
        support. The establishment of the Child Support Guidelines or the adoption of any
        substantive modifications to the guidelines may constitute a change in circumstances
        sufficient to permit review of the support order. The most current guidelines shall be
        used to calculate the amount of the child support obligation. The court may refer the
        issue of child support modification to the court trustee for investigation. The trustee may
        then investigate all matters pertinent to the determination of changed circumstances and
        a suitable child support award and shall submit findings and recommendations to the
        court. The investigation by the trustee is an available remedy for every order of child
        support or alimony which provides for payments to be made through the court.
 HRS �571-52.1, 576D-7, and 580-47.
 The court may modify the maintenance provisions of a decree or order at any
        time upon a showing of a change in the circumstances of either party since the entry of
        any prior decree or order for maintenance. The fact that the moving party may be in
        default or arrears shall not necessarily constitute a bar to the granting of a hearing of that
        party�s motion for modification. Unless otherwise provided in the final decree or order,
        remarriage of the party receiving maintenance terminates maintenance. The remarried
        party shall file a notice of the remarriage with the court within thirty days of such
        remarriage and send a copy of the notice to the party paying maintenance. The failure
        to file a notice of remarriage shall be considered by the court in awarding attorney fees
        and costs in any subsequent proceeding.  HRS �580-47 and 580-51.
 IDAHOThe maintenance and child support provisions of a Decree may be modified only
        as to installments accruing subsequent to the Motion for Modification and only upon a
        showing of a substantial and material change of circumstances. In the case of child
        support modification, the amount of child support calculated pursuant to the Idaho Child
        Support Guidelines may, but not necessarily shall, constitute a substantial and material
        change of circumstances. A child support order may be modified to provide for health
        insurance for the minor children, if not provided in the prior Order or Decree. 
        IC �32-709; and Section 5, Idaho Child Support Guidelines, Rule 6(c) (6), Idaho
        Rules of Civil Procedure.
 ILLINOISThe maintenance or child support provisions of a judgment may be modified upon
        a showing of a substantial change in circumstances. Child support may be modified
        without the necessity of showing a substantial change in circumstances if there is a
        change of at least 20% between the amount of the existing order and the amount of child
        support which would result from application of the child support guidelines. 
        750 ILCS 5/510.
 INDIANAProvisions of an order or decree for child support or maintenance may be
        modified or revoked. Modification shall be made only: 1) upon a showing of changed
        circumstances so substantial and continuing as to make the terms unreasonable; or 2)
        upon a showing that the existing child support order differs by more than 20%
        from
        the amount that would be ordered by applying the child support guidelines, and the
        existing order was issued at least 12 months before the modification petition was filed.
 AIC �31-1-11.5-17.
 IOWAThe court may modify child support and spousal support orders when there is a
        substantial change in circumstances. In determining whether there is a substantial
        change in circumstances, the court shall consider the following factors: 1) changes in the
        employment, earning capacity, income or resources of a party; 2) receipt by a party of an
        inheritance, pension or gift; 3) changes in the medical expenses of a party;
        4) changes in the number or needs of dependents; 5) changes in the physical, mental, or
        emotional health of a party; 6) changes in the residence of a party; 7) remarriage of a
        party; 8) the possible support of a party by another person; 9) changes in the needs of a
        party whose support is governed by the order; 10) contempt by a party of existing court
        orders; 11) other factors the court determines to be relevant in an individual case.
        Regardless of these factors, the court will find that a substantial change of
        circumstances exists with respect to a child support order when the child support varies
        by 10% or more from the amount which would be due pursuant to the most current child
        support guidelines. Also, a substantial change of circumstances will exist if the obligor
        has access to a health benefit plan, the current order for support requires medical
        support, and the children are not covered by a health benefit plan provided by the
        custodial parent.
 ICA Section 598.21.
 KANSASThe court may modify the child support provisions of a decree or order when
        there has been a material change in circumstances. Modification may be made
        retroactive to a date at least one month after the date that the motion to modify was filed
        by the court. Any of the following circumstances may constitute a material change of
        circumstance to allow the court to modify an existing support order: 1) a change in the
        financial circumstances of the parents or the guidelines which would increase or
        decrease by ten percent or more the child support calculated pursuant to the guidelines;
        an increase in the custodial parent�s gross income is not a material change of
        circumstances for the purpose of increasing the child support obligation; 2) the seventh
        and sixteenth birthdays of the child; 3) emancipation of a child; 4) a party�s failure to
        comply with the conditions of a court ordered adjustment to child support, for example, a
        party�s failure to exercise visitation rights or a party�s failure to obtain private schooling
        for the children if that was the basis for the court�s award.
 KSA �60-160(a) and Kansas Child Support Guidelines.
 A change of the residence of a child to another state or removal of a child from
        Kansas for a period of time exceeding 90 days may be considered a material change of
        circumstances which would justify modification of a child support order. 
        KSA �60-1620(c)
 The maintenance provision of a decree may be modified upon a showing of a
        material change of circumstances. The court may make a modification of maintenance
        retroactive to a date at least one month after the date that the motion to modify was filed
        with the court. The court may modify the amounts or other conditions for the payment of
        any portion of the maintenance which was originally awarded in the decree but has not
        already become due. However, no modification under such circumstances shall be
        made without the consent of the party liable for the maintenance if it has the effect of
        increasing or accelerating the liability for the unpaid maintenance beyond what was
        ordered in the original decree.
 KSA �60-1610(b).
 KENTUCKYUnless the parties have precluded or limited modification of maintenance by the
        terms of their separation agreement, the maintenance provisions of a decree may be
        modified only upon a showing of changed circumstances so substantial and continuing
        as to make the terms unconscionable. Unless otherwise agreed in writing or expressly
        provided in the decree, the obligation to pay future maintenance is terminated upon the
        death of either party or the remarriage of the party receiving maintenance.
 K.R.S. �403.250.
 The child support provisions of a dissolution decree may be modified only upon a
        showing of material change in circumstances that is substantial and continuing. The
        Kentucky child support guidelines may be used as evidence of a material change in
        circumstances. If application of the guidelines results in a 15% or more change in the
        amount of child support, it shall be rebuttably presumed to be a material change in
        circumstances. Application of the guidelines which results in less than a 15% change in
        the amount of support shall be rebuttably presumed to not be a material change in
        circumstances.  K.R.S. �403.213.
 LOUISIANAAn award of child support may be modified if the circumstances of the child or of
        either parent change. An award of child support shall be terminated upon proof that it
        has become unnecessary. A voluntary reduction of income by the paying spouse, or
        other voluntary act, does not constitute a change of circumstances. 
        CC Art. 142.
 An award of periodic payments of alimony may be modified or even terminated if
        there have been substantial changed circumstances since the decree. Periodic alimony
        shall be terminated if the recipient spouse remarries or enters into open
        concubinage, which means openly in a relationship of cohabitation or quasi-marital relations. An award
        of lump sum alimony, whether payable in one payment or in installments, is not subject
        to modification and does not terminate upon the recipient�s remarriage or entering into
        open concubinage, and does not terminate upon either spouse�s death. 
        CC Art. 112.
 If the Department of Social Services is providing support enforcement services, a
        change in circumstances exists if application of the child support guidelines results in at
        least a 25% change in the existing child support award.  RS 9:311.
 MAINEThe child support provisions of a decree or existing support order may be
        modified by showing of a substantial change of circumstances since the time of the
        decree or order. If application of the child support guidelines varies from the prior
        support amount by more than 15%, the court shall consider the variation a substantial
        change of circumstances. Maine law provides for an expedited procedure for
        modification of child support orders. The party seeking modification must serve on the
        other party a written motion for modification, a notice that the court may enter an order
        without a hearing if the party does not request a hearing, a notice that Maine law
        requires mediation prior to any hearing, the Income Affidavit of the moving party, and a
        proposed order which incorporates the child support worksheet and the amount of
        support from the guidelines. The other party must request a hearing within 30 days after
        being served with the motion for modification and the supporting affidavit, worksheet,
        and other documentation. If a party requests a hearing, the motion must be referred for
        mediation prior to the court hearing. If a party does not request a hearing within 30 days
        after service, the court may enter an order modifying support without a court hearing
        using the proposed order, provided that the proposed modified support obligation is
        equal to or greater than the amount which results from application of the guidelines. If a
        downward deviation is proposed, the court shall hold a hearing prior to entering an order. 
        19 MRSA �319.
 The alimony provisions of a decree may be altered by the court at any time when
        it appears that it is required by justice. However, a court shall not increase alimony if the
        original decree prohibits an increase. In making an alteration to the alimony award, the
        court shall consider the factors which are required to be considered at the time of an
        original award of alimony.  19 MRSA �721.
 MARYLANDThe child support and alimony provisions in a decree can be modified upon a
        showing of material changes in the circumstances since the entry of the decree. The
        amount of child support calculated by reference to the Child Support Guidelines may not
        be grounds for requesting a modification of a Child Support Award, unless the use of the
        guidelines would result in a change in the award of 25% or more, in which case it will
        constitute a material change in circumstances.  ACM �12-202
 The court may modify any provisions in a decree with respect to alimony, unless
        there is: 1) an express waiver of alimony, or 2) a provision that specifically states that the
        provisions with respect to alimony are not subject to any court modification. 
        ACM �8-103.
 Subject to ACM 8-103, the court may extend the period for which alimony is
        awarded if: 1) circumstances arise during the period that would lead to a harsh and
        inequitable result without an extension; and 2) the recipient requests an extension of
        alimony during the period of the award. Subject to ACM 8-103, the court may modify the
        amount of alimony awarded as circumstances and justice require.  ACM �11-107.
 Unless the parties agree otherwise, alimony terminates: 1) on the death of either
        party; 2) on the marriage of the recipient; or 3) if the court finds that termination is
        necessary to avoid a harsh and inequitable result.
 ACM �11-108.
 MASSACHUSETTSThe child support provisions of a decree or prior order can be modified if the court
        finds that a material and substantial change in circumstances of the parties has
        occurred, and the modification is necessary for the best interest of the children. The
        child support provision in a decree or a prior order shall be modified if there is an
        inconsistency between the amount of the existing order and the amount that would result
        from application of the child support guidelines. The child support provision of a decree
        or order can also be modified if necessary to provide for the health care coverage for the
        child, which shall be modified whether or not a modification in the amount of child
        support is necessary.  ALM 208 �28.
 The alimony provisions in a decree can be modified by the court at any time. The
        court may consider the same circumstances which it considered at the time of the
        divorce and can make any decision with respect to alimony which it might have made in
        the original decree.
        ALM 208 �37.
 MICHIGANThe child support and maintenance provisions of a decree can be modified by the
        court, at the request of either party, upon a showing of substantial changes in the
        circumstances. With respect to child support, if there have been substantial changes in
        the circumstances, the court shall then order support in an amount determined by
        application of the child support formula, unless it is appropriate to deviate from the
        formula because the application would be unjust or inappropriate under the facts of the
        case.
 With respect to alimony, the court has the ability to modify or terminate
        permanent alimony upon a showing of substantial changes in circumstances, so long as
        the alimony awarded originally was in the form of period payments instead of a lump sum
        payment. The primary issue in a modification request is whether there have been
        substantial changes in circumstances since the entry of the last order for maintenance or
        child support.  MCLA �552.17 and �552.28.
 MINNESOTAThe child support and spousal maintenance provisions in a Decree can be
        modified upon a showing of one or more of the following: 1) substantially increased or
        decreased earnings of a party; 2) substantially increased or decreased need of a party or
        the children; 3) receipt of public assistance; 4) a change in the cost of living for either
        party which makes the terms unreasonable and unfair; 5) extraordinary medical
        expenses of the child not provided for in the Decree; or 6) the addition of work-related or
        education-related child care expenses or a substantial increase or decrease in such child
        care expenses.

 The custodial parent may move the residence of children to another state if the
        non-custodial parent agrees or if the court allows it. Based on recent decisions by the
        Minnesota Supreme Court, the court will generally presume that removal out of state by
        the custodial parent is in the best interest of the child, and, therefore, the court will grant
        permission to move unless the non-custodial parent proves by a preponderance of the
        evidence that moving out of state is not in the best interest of the child.
 Minn. Stat. �518.175.
 MISSISSIPPIThe child support provisions in a decree or order may be modified upon a
        showing of a material change of circumstances of one or more of the parties - either
        parent or the child - which has arisen subsequent to the decree or last court order. 
        MC 93-11-65.
 The alimony provision in a decree can be modified upon a showing of a material
        change of circumstances which occurred subsequent to the decree. However, periodic
        payments of alimony can be modified whereas lump sum alimony cannot be modified.
        Periodic payments of alimony terminate automatically upon the death of the obligor or
        upon the remarriage of the obligee, the party receiving alimony. Periodic alimony can be
        modified in the event of a material change in circumstances which occurred subsequent
        to the decree which awarded alimony. In contrast, lump sum alimony is an order by the
        court for lump sum payments, either in a single lump sum or in fixed periodic
        installments. Lump sum alimony represents a final settlement between the parties and
        may not be changed or modified by either party subsequent to the decree, absent fraud
        or some other basis for reopening the Judgment and Decree.  MC 93-5-23.
 MISSOURIThe maintenance and child support provisions of a decree may be modified upon
        only a showing of changed circumstances so substantial and continuing as to make the
        terms unreasonable. In determining whether or not a substantial change in
        circumstances has occurred, the court shall consider all financial resources of both
        parties, including the extent to which the reasonable expenses of either party are or
        should be shared by a spouse or other person with whom he or she cohabits, and the
        earning capacity of a party who may not be employed. If the application of the child
        support guidelines would result in a change of child support by 20% or more, then there
        is a rebuttable presumption that there is a change of circumstances so substantial and
        continuing as to make the present terms of support unreasonable. When a party
        seeking modification of child support has proved changed circumstances so substantial
        and continuing as to make the terms unreasonable, then future child support shall be
        determined according to the child support guidelines.
 If a maintenance order includes a termination date, the court may modify
        maintenance based upon a substantial and continuing change of circumstances which
        occurred prior to the termination date. Unless otherwise agreed in writing or expressly
        provided in the decree, the obligation to pay maintenance is terminated upon the death
        of either party or the remarriage of the party receiving maintenance.
        VAMS �452.370 and �452.335.
 MONTANAProvisions of the decree regarding maintenance and support may only be
        modified upon a showing of changed circumstances so substantial and continuing as to
        make the terms uncountable. A modification may not be made within 12 months after
        the establishment of the Order or the most recent modification. The nonexistence of a
        medical support order justifies an immediate modification of child support in order to
        provide for the actual or anticipated costs of the child�s medical care.
 Unless otherwise agreed to in writing or expressly provided in the decree, the
        obligation to pay maintenance is terminated upon the death of either party or the
        remarriage of the party receiving maintenance.
 MCA 40-4-208.
 NEBRASKAThe alimony provisions in a decree may be modified or revoked upon a showing
        of good cause, which means a material and substantial change in circumstances. Good
        cause depends upon the circumstances of each case. In order to request modification of
        alimony, the petitioning party must be current in alimony accrued prior to the date of
        service of the motion. Except as otherwise agreed by the parties in writing or by order of
        the court, alimony orders shall terminate upon the death of either party, or the remarriage
        of the recipient.  Reissued Revised Statutes 42-365.
 Child support provisions in a decree may be modified upon a showing of a
        material change of circumstances. Application of the Child Support Guidelines can be
        used to prove a material change. If application of the guidelines results in a variation in
        the amount of child support by 10% or more, due to financial circumstances which
        have lasted at least six months and can reasonably be expected to last for an additional
        six months, it is presumed that there has been a material change of circumstances.

 NEVADAThe child support provisions of a divorce decree or other court order may be
        reviewed at any time on the basis of changed circumstances. A child support order must
        be reviewed by the court at least every three years to determine whether the order
        should be modified or adjusted. If the court determines that modification is appropriate,
        the court shall enter an order modifying the previous order for support. Any review of a
        support order must utilize the Nevada child support formula. Review of a child support
        order may be requested by either parent or by the welfare division of the Department of
        Human Resources or by the District Attorney.
 NRS 125B.145.
 The alimony provisions of a decree may be modified upon a showing of changed
        circumstances. If the decree provides for specified periodic payments of alimony,
        accrued payments cannot be modified. Payments which have not accrued at the time a
        motion for modification is filed may be modified upon a showing of changed
        circumstances, whether or not the court has expressly retained jurisdiction for the
        modification. In determining whether to modify alimony, the court shall consider whether
        the income of the payor spouse, as shown by that spouse�s tax return for the prior year,
        has been reduced to such a level that the spouse is financially unable to pay the current
        award of alimony.  NRS 125.150.7.
 NEW HAMPSHIREThe child support provisions of the divorce decree or order may be modified by
        the court upon a showing of substantial change of circumstances. However, either party
        may apply to the court for modification of child support three years after the entry of the
        last support order, without having to show a substantial change of circumstances.
 RSA 458-C:7.
 The alimony provisions of a decree may be modified by the court whenever
        modification would be just and equitable. Upon the renewal, modification, or extension
        of a prior order for alimony, the court may order alimony to be paid for such length of
        time as the parties may agree or the court orders. The court may consider all the factors
        which it could have considered at the time of the initial determination of an alimony
        award. In any proceeding for modification of an existing alimony order, the income of the
        obligor�s current spouse shall not be considered a source of income for the purpose of
        modification, unless the obligor resigns from or refuses employment or is voluntarily
        unemployed or underemployed, in which case the income of the subsequent spouse
        may be imputed to the obligor only to the extent that such obligor could have earned
        income in his usual employment. The unanticipated consequences of changes and
        federal tax laws may be grounds to modify any alimony order or agreement.
 RSA 458:14 and 458:19.
 NEW JERSEYAn award of rehabilitative alimony may be modified based either upon changed
        circumstances or upon the non-occurrence of circumstances that the court found would
        occur at the time of the award. The court may also modify permanent alimony awards,
        based upon a showing of changed circumstances. Remarriage of the recipient spouse
        terminates an award of permanent alimony, except that any arrearages that have
        accrued prior to the date of remarriage shall not be vacated. The remarriage of a former
        spouse receiving rehabilitative alimony shall not be a cause for termination of the
        rehabilitative alimony unless the court finds a change of circumstances or the nonoccurrence
        of circumstances upon which the award was based.  NJSA 2A:34-23 and 34-25.
 When a motion is brought for modification of a prior order or judgment for child
        support or alimony, a copy of the prior order or decree sought to be modified shall be
        attached to an Affidavit filed in support of the motion. Also, the party shall attach to a
        supporting Affidavit a copy of the Case Information Statement filed by the party at the
        time the prior order or decree was entered. The party shall also provide a current Case
        Information Statement, which provides information about income, expenses, assets, and
        liabilities of the party.  Rule 5:5-4, New Jersey Rules of Court.
 The child support provisions of a decree or child support order can be modified
        upon a showing of changed circumstances. Before the child support guidelines can be
        used to modify the amount of child support in a prior order, the court must first determine
        whether there are changed circumstances which would justify a change in the existing
        child support order. Once the court determines that circumstances have changed
        sufficiently to justify any change, then the court shall apply the guidelines to determine
        the amount of appropriate child support.

 NEW MEXICOA child support obligation can be modified upon a showing of material and
        substantial changes in circumstances subsequent to the adjudication of the existing
        order. There shall be a presumption of a material and substantial change in
        circumstances if application of the child support guidelines results in a deviation upward
        or downward of more than 20% of the existing child support order, and the Petition for
        modification is filed more than one year after the filing of the existing child support order.
        Where child support cases are being enforced by the Human Services Department, the
        Department shall review child support orders at least every 36 months.

 The alimony provisions of a decree can be modified upon a showing of changed
        circumstances. Remarriage of the recipient will generally constitute such a change of
        circumstances as to require alimony to be terminated, unless the recipient can prove
        extraordinary conditions justifying continuing the periodic alimony. The court has the
        power, in the original dissolution decree, to designate alimony as non-modifiable with
        respect to the amount or duration of the alimony payments.
 �40-4-7 NMSA.
 NEW YORKUpon application by either party, the court may modify any prior order or
        judgment as to spousal maintenance or child support, upon a showing of a recipients
        inability to be self supporting, or a substantial change in circumstance, or termination of
        child support. If the spousal maintenance divisions of a decree are based upon a written
        separation agreement between the parties, the maintenance will not be modified, except
        upon the showing of extreme hardship on either party, on which event the judgment as
        modified shall supersede the terms of the prior judgment for such a period of time and
        under such circumstances as the court determines. No modification shall reduce or
        annul any child support arrears which have occurred prior to the date of the motion for
        modification. The court shall not reduce or annul any spousal maintenance arrears
        which have been reduced to judgment prior to the modification motion. Spousal
        maintenance arrears which have accrued prior to the modification motion, but not yet
        reduced as to judgment, may not be modified or annulled by the court unless the
        defaulting party shows good cause for failure to apply for relief from the judgment prior to
        the accrual of the arrears and the facts and circumstances constituting good cause are
        set forth in a written memorandum of decision by the court.
 Domestic Relations Law �236 (9).
 Spousal maintenance terminates upon remarriage of the recipient. In its
        discretion, the court may modify spousal maintenance provisions in the decree if the
        husband applies for modification on the grounds that the former wife is habitually living
        with another man and holding herself out as his wife, although not married to such man.
        (As of 1995, the New York legislature has failed to make the language of this statute
        gender-neutral. Presumably, a woman could apply to the court for modification of
        spousal maintenance being paid to the man upon proof that the man was residing with
        another woman and holding himself out as her husband.)
 Domestic Relations Law �248.
 NORTH CAROLINAThe child support provisions of a decree or order may be modified or vacated at
        any time, upon motion and a showing of changed circumstances. When an order for
        child support has been entered by a court of another state, a North Carolina court may,
        upon a showing of changed circumstances, and if the child or custodial parent is within
        the jurisdiction of the court, enter a new order for support which modifies or supersedes
        the other state�s child support order.
        GS �50-13.7.
 The alimony provisions of a decree may be modified or vacated at any time, upon
        a motion by either party and upon a showing of changed circumstances. Alimony shall
        terminate upon the remarriage or cohabitation of the recipient. Alimony shall terminate
        upon the death of either party. Cohabitation means the act of two adults dwelling
        together continuously and habitually in a private heterosexual or homosexual
        relationship. Cohabitation is indicated by the voluntary mutual assumption of those
        marital rights, duties, and obligations which are usually manifested by married people,
        including but not limited to, sexual relations.

 A custodial parent may not change the residence of the child to another state
        except upon order of the court or with the consent of the non-custodial parent, if the
        non-custodial
        parent has been given visitation rights by the decree. A court order is not
        required if the non-custodial parent: 1) has not exercised visitation rights for a period of
        one year, or 2) has moved to another state and is more than 50 miles from the residence
        of the custodial parent.  NDCC �14-09-07.
 OHIOThe child support provision of an order or decree may be modified upon a
        showing of a substantial change in circumstances since the date of the order or decree.
        If the child support varies by 10% or more by application of the current child support
        schedule, the court shall consider the variance to constitute a substantial change of
        circumstances to require a modification of the child support order. If the court
        determines that the amount of child support in the existing order does not adequately
        meet the medical needs of the child, the inadequate coverage shall be considered by the
        court as a substantial change of circumstances to require a modification of child support.

 If a continuing order for periodic payments of money as alimony is entered in a
        divorce or dissolution of marriage action that is determined on or after 5-2-86 and before
        1-1-91, or if a continuing order for periodic payments of money as spousal support is
        entered in a divorce or dissolution of marriage action that is determined on or after 1-1-
        91, the court does not have jurisdiction to modify the amount or terms of the spousal
        support unless the court determines: 1) that the circumstances of either party have
        changed; and 2) the decree contains a provision specifically authorizing the court to
        modify the amount or terms of spousal support. A change in the circumstances of a
        party includes, but is not limited to, any increase or involuntary decrease in the party�s
        wages, salary, bonus, living expenses, or medical expenses.  ORC 3105.18.
 OKLAHOMAThe child support provisions of the divorce decree or an order may be modified if
        the support amount is not in accordance with the child support guidelines or upon other
        material change in circumstances. In all cases where child support rights have been
        assigned to the county, the Department of Human Services shall review child support
        orders at least every 36 months, to determine whether the amount of child support is in
        accordance with the child support guidelines. In all the cases in which child support
        services are being provided by the county, the Department shall conduct a review of the
        child support upon the request of either party. If the Department determines that child
        support awards are not in accordance with the guidelines, the case shall be presented to
        the District or Administrative Court for modification.  43 Okl.St.Ann. �118B19 and 118.1.
 The alimony provisions of any divorce decree may be modified upon proof of
        changed circumstances relating to the need for support or ability to support which are
        substantial and continuing so as to make the terms of the decree unreasonable to either
        party. The court shall provide in the decree that alimony terminates upon the death or
        remarriage of the recipient. The voluntary cohabitation of a former spouse with a
        member of the opposite sex shall be a ground to modify alimony. If voluntary
        cohabitation is alleged in a motion to modify payment of alimony, the court shall have
        jurisdiction to reduce or terminate future alimony upon proof of substantial change of
        circumstances of either party to the divorce, relating to need for support or ability to
        support. The term cohabitation means the dwelling together continuously and habitually
        of a man and a woman or in a private conjugal relationship not contracted as a marriage
        according to law.  43 Okl.St.Ann. �134.
 OREGONThe court may modify the child support provisions of a decree if a party proves a
        substantial change of economic circumstances of a party, which may include, but is not
        limited to, a substantial change in the cost of reasonable and necessary expenses to
        either party. The court may terminate a duty of child support for any minor child who has
        become self-supporting, emancipated, or married. The court may suspend future child
        support for any child who has ceased to be a �child attending school� - a child enrolled in
        an educational course load of less than one-half that determined by the educational
        facility to constitute full-time enrollment is not considered to be a child attending school.
        If the motion for modification of child support is brought by the child support obligor to
        reduce or terminate child support on the grounds of a reduction in income, the court shall
        not find a sufficient change in circumstances if the motion is based upon the obligor�s
        voluntary reduction in income due to voluntary retirement, partial voluntary retirement, or
        any other voluntary reduction of income or self-imposed curtailment of earning capacity,
        if it is shown that such action of the obligor was not taken in good faith, but was for the
        primary purpose of avoiding child support.  ORS 107.135 and 107.108.
 The spousal maintenance provisions of a decree can be modified by the court
        upon a showing of a substantial change in economic circumstances of a party. If the
        decree provided for a termination or reduction of maintenance at a designated age, in
        anticipation of the commencement of pension, social security, or other entitlement
        payments, and if the obligee is unable to obtain the anticipated payments, that inability is
        a sufficient change in circumstances for the court to modify the maintenance provisions
        in the decree. In considering whether to modify the decree, and in considering whether
        there has been a substantial change in circumstances, the court shall consider income
        opportunities and benefits of the respective parties from all sources. If the basis of a
        motion for modification is the voluntary reduction in income by the obligor, the court will
        determine whether the obligor�s action was not taken in good faith but was for the
        primary purpose of avoiding the maintenance obligation. Whenever spousal
        maintenance is terminated by the court, the court has the power to order a reinstatement
        of the maintenance if 1) the basis for the termination ceases to exist; and 2) the
        reinstatement motion is filed within the period of time that maintenance would have been
        paid, but for the termination by the court. If the obligor has been paying maintenance in
        installments for more than ten years after the decree, and if the recipient spouse has not
        made a reasonable effort during that period of time to become financially self-supporting
        and independent of the maintenance provided in the decree, the obligor may petition the
        court to modify or terminate the spousal maintenance award. The court shall conduct a
        hearing to determine whether the maintenance provision of the decree shall be set aside.
        If the court finds that the recipient has not made a reasonable effort during the previous
        ten years to become financially self-supporting and independent of the maintenance
        provided in the decree, the court shall order the maintenance terminated. In making its
        findings, the court shall consider: 1) the age of the party receiving maintenance; 2) the
        health, work experience, and earning capacity of the party receiving maintenance; 3) the
        circumstances of any minor children; and 4) efforts made by the recipient party during
        the previous ten years to improve opportunities for gainful employment including
        attendance at any school or training. However, the court may not terminate maintenance
        for the support of a party who is 60 years of age or older at the time the modification
        proceeding is held.  ORS 107.135, 107.136, 107.407, and 107.412.

        application of new or revised support guidelines, that may constitute a material and
        substantial change in circumstances. Both parties are required to notify the domestic
        relations section in writing within seven days of any material change in circumstances
        relevant to the level of support or the administration of the support order, including, but

        that notice of a Petition to modify was given to the adverse party, and only if the court
        finds that a substantial change in circumstances has occurred. A child support order

 The alimony provisions in a decree may be modified whenever the court finds
        that a substantial change in circumstances has occurred. The court may make any
        change to the award of alimony based upon the same factors and circumstances which
        the court may consider in making the initial award in alimony. The court has the power to
        alter, amend, or terminate any award of alimony previously made. The obligation to pay
        alimony automatically terminates upon the remarriage of the recipient.

 SOUTH CAROLINAThe South Carolina Family Court has the authority to modify any decree or order
        regarding child support as the court considers necessary upon a showing of changed
        circumstances. The court may not modify any installments of child support which
        accrued prior to the filing and service of a motion to modify support. Except for public
        assistance cases, application of the child support guidelines to an existing child support
        order does not, by itself, constitute a change in circumstances.
 1976 Code �20-7-852 and �20-7-933.
 The provisions in a decree or other court order for periodic payments of alimony
        can be modified upon a showing that the circumstances of the parties or the financial
        ability of the payor have changed since the decree was issued. A remarriage of the
        recipient spouse normally results in termination of periodic payments of alimony.
 1976 Code �20-3-150 and �20-3-170.
 SOUTH DAKOTAChild support provisions of an order or the divorce decree may be modified upon
        a showing of a change of circumstances. Either party may petition the court for an
        increase or decrease of child support based on a change of circumstances. A hearing is
        held before a Referee who is an attorney appointed by the court to hear modification
        issues. The Referee shall file a report with the court. Any party shall have ten days from
        the date of service of the report to object to the Referee�s report. If no objection is filed,
        the Circuit Court may thereafter and without further notice enter its order approving the
        report. If an objection is filed, the Circuit Court shall have a hearing solely on the records
        before the Referee to adopt the Referee�s report, modify it, or reject it and remand it for
        further hearing.
 S.D.C.L. 25-7A-22.
 All orders for child support entered and in effect prior to July 1, 1989 may be
        modified in accordance with the child support schedule without requiring a showing of a
        change in circumstances from the time of entry of the prior support order. 
        S.D.C.L. 25-7-6.13.
 Alimony provisions of a decree may be modified upon proof of a change in
        circumstances. The burden of proving a change in circumstances sufficient to justify
        modification of an alimony award is upon the party seeking modification. 
        S.D.C.L. 25-4-41.
 TENNESSEEUpon application of either party, the court shall decree an increase or decrease in
        the amount of child support pursuant to a prior order or decree, when there is a
        significant variance between the amount of support currently paid and the amount of
        support which would be established by the current child support guidelines - unless the
        variance results from a previously court-ordered deviation from the guidelines and the
        circumstances which caused the deviation have not changed. Also, the necessity to
        provide for the child�s health care needs shall be a basis for modification of the support
        order, regardless of whether a modification in the amount of support is necessary. The
        court may consider a request to modify a child support order even if the requesting party
        is in arrears under that order, unless the arrearage is a result of intentional action by the
        party.  TCA �36-5-101(a)(1).
 The court may modify an award of alimony upon a showing of a substantial and
        material change of circumstances. In all cases where a person is receiving alimony in
        the future or has a right to receive alimony in the future, the amount of which cannot be
        calculated on the date of the divorce decree, the right to receive future alimony
        automatically terminates upon the remarriage of the recipient. The recipient shall notify
        the obligor of remarriage, timely upon remarriage. Failure of the recipient to timely give
        notice of the remarriage will allow the obligor to recover all amounts paid as future
        alimony after the date of the recipient�s marriage. In all cases where an alimony recipient
        lives with a third person, a rebuttable presumption is raised that 1) the third person is
        contributing to the support of the alimony recipient, and the alimony recipient therefore
        does not need the amount of spousal support previously awarded, and the court shall
        suspend all or part of the alimony; or 2) the third person is receiving support from the
        alimony recipient, and the alimony recipient therefore does not need the amount of
        alimony previously awarded, and the court should suspend all or part of the alimony. 
        TCA �36-5-101(a)(1)-(3).
 TEXASThe child support provisions of the divorce decree or prior child support order
        may be modified if the circumstances have materially and substantially changed since
        the date of the decree or order. The court may consider the Texas Child Support
        Guidelines to determine whether there has been a material or substantial change of
        circumstances. If the amount of support contained in the order does not substantially
        conform with the support calculated pursuant to the current Guidelines, the court may
        modify the order to substantially conform with the Guidelines if the modification is in the
        best interest of the child. A court may consider other relevant evidence in addition to the
        factors listed in the Guidelines. A history of support voluntarily provided in access of the
        court order does not constitute cause to increase the amount of an existing child support
        order. The court may not add any portion of the net resources of a new spouse to the
        net resources of a child support obligor in order to calculate the amount of child support
        to be awarded upon a request for modification. Likewise, the court may not subtract the
        needs of a new spouse or of a dependent of a new spouse, from the net resources of
        the child support obligor upon a request for modification. An increase in the needs,
        standard of living, or lifestyle of the obligee does not justify an increase in the obligor�s
        child support obligation.  V.T.C.A., Family Code �156.401-.405.
 The maintenance provision in a decree or prior order may be modified by the
        court upon a showing of a material and substantial change in circumstances of either
        party. The court shall apply any modification only to payments accruing after the filing of
        the motion to modify.
 V.T.C.A., Family Code �3.9608.
 UTAHChild support and alimony provisions of a decree can be modified upon a
        showing of a substantial change in circumstances.
 The court has continuing jurisdiction to make changes and new orders regarding
        alimony based on a substantial material change in circumstances not foreseeable at the
        time of divorce. The court may not modify alimony to address needs of the recipient that
        did not exist at the time the decree was entered, unless the court finds extenuating
        circumstances that justify that action. In modifying alimony, the income of any
        subsequent spouse of the payor may not be considered. However, the court may
        consider the new spouse�s financial ability to share living expenses. Also, the court may
        consider the income of a new spouse if the court finds that the payor�s improper conduct
        justifies that consideration.
 Alimony may not be ordered for a duration longer than the number of years that
        the marriage existed unless, at any time prior to termination of alimony, the court finds
        extenuating circumstances that justify the payment of alimony for a longer period of time.
 Unless a decree specifically provides otherwise, any order for payment of alimony
        automatically terminates upon the remarriage or cohabitation of the former spouse. 
        UCA 30-3-5.
 VERMONTAny proceedings for modification of the child support and maintenance provisions
        of a decree or order shall be by motion, supported by affidavit. The motion and affidavit
        shall be served upon the parties and not their attorneys. Affidavits shall set forth specific
        facts and shall be based upon the parties own knowledge, information, or belief. If a
        hearing is to be held on a motion to modify, the court may bifurcate the hearing and first
        determine and make findings as to whether there has been a real, substantial and
        unanticipated change of circumstances. If no such change is found, the court may
        dismiss the motion without reaching the merits of the action. When the motion is for
        modification of child support, the moving party shall also file certified copies of the
        Affidavit of Income and Assets and the financial worksheet from the original proceeding.
 Rule 4(j), Vermont Rules for Family Proceedings.
 The child support provisions of a decree can be modified upon a showing of a
        real, substantial and unanticipated change of circumstances. The court can modify a
        child support order, whether or not the order is based upon a stipulation or agreement of
        the parties. If the child support order varies more than 10% from the amounts required
        to be paid under the Vermont child support guidelines, that shall be considered a real,
        substantial and unanticipated change of circumstances. A motion to modify a support
        order shall be supported by an affidavit stating calculations demonstrating that the party
        is entitled to a modification of the support order. The clerk of court shall enter an order
        modifying the support award in accordance with the calculations, unless within 15 days
        after service of the modification motion of the adverse party, either party requests a
        hearing. The court shall conduct a hearing within 20 days of the request. No order shall
        be modified without a hearing if a hearing is requested.  15 VSA Section 660.
 The maintenance provisions of a decree can be modified upon a showing of a
        real, substantial, and unanticipated change of circumstances. The court can modify
        maintenance whether or not the maintenance decree is based upon a stipulation or an
        agreement of the parties. Remarriage of the recipient spouse does not automatically
        terminate the maintenance award. It is within the trial court�s discretion to order
        termination of maintenance payments in the event that the recipient remarries or
        cohabitates.
 15 VSA Section 758.
 VIRGINIAThe child support provisions in a divorce decree or other support order may be
        modified by the court if there has been a material change in circumstances since the
        prior court order. The Virginia Child Support Guidelines became effective July 1, 1989.
        If the original decree or child support order was made before the effective date of the
        guidelines, the moving party may satisfy the material change in circumstances
        requirement by showing that the amount of the existing child support order varies
        significantly from the amount which would be calculated pursuant to the guidelines. On
        the other hand, if the decree or prior child support order was made after the effective
        date of the guidelines, a significant variation between the existing child support order and
        the amount which would be calculated pursuant to the guidelines is not sufficient to
        justify modifying the award without the moving party proving some material change in
        circumstances.  CV �20-108 and �20-108.2.
 The provisions of a decree or court order which provide for periodic payments of
        spousal maintenance may be modified by a showing of changed circumstances.
        Spousal maintenance automatically terminates upon the death or remarriage of the
        recipient.  CV �20-107.1, 20-109, and 20-110.
 WASHINGTONThe child support and maintenance provisions of a decree may be modified only
        upon a showing of substantial change of circumstances. With respect to spousal
        maintenance, the parties have the right to agree in their Separation Contract that the
        court�s power to modify spousal maintenance is limited or even precluded. Unless
        otherwise agreed in writing or provided in the decree, the obligation to pay future
        maintenance is terminated upon the death of either party or the remarriage of the party
        receiving maintenance.
 With respect to child support, the parties may not limit or preclude the court�s
        power to modify future child support obligations. Child support can always be modified
        upon a showing of a substantial change of circumstances. An order for child support
        may be modified one year or more after it has been entered without a showing of
        substantial change of circumstances in the following cases: 1) if the order in practice
        works a severe economic hardship on either party or the child; 2) if a party requests an
        adjustment in an order for child support which was based on guidelines which
        determined the amount of support according to the child�s age, and the child is no longer
        in that age category; 3) if child support is terminating due to the child turning 18 but the
        child is still in high school, and there is a need to extend support in order to complete
        high school; or 4) to add an automatic adjustment of support provision.
 An obligor�s voluntary unemployment or voluntary underemployment, by itself, is
        not a substantial change of circumstances.
 All child support decrees may be adjusted once every 24 months based upon
        changes in the income of the parents, without a showing of substantially changed
        circumstances. Either party may initiate the adjustment by filing a motion and the
        mandatory child support worksheets. A party may petition for modification of child
        support on the grounds of substantially changed circumstances at any time. However, if
        relief is granted on the grounds of substantially changed circumstances, then 24 months
        must pass before another motion can be filed. An order for child support may be
        adjusted 24 months from the date of entry of the decree or the last adjustment for
        modification, whichever is later, simply based upon changes in the child support
        guidelines in RCW �26.19.
        RCW �26.09.170.
 WEST VIRGINIAThe child support provisions of a divorce decree can be modified by the showing
        of a substantial change of circumstances since the entry of the decree. If the amount of
        the prior child support order varies by 15% or more from the amount which would be
        calculated pursuant to the current child support guidelines, that shall constitute a
        substantial change in circumstances. Once the court has found that a change of
        circumstances has occurred which will justify modification of child support, then the
        amount of child support shall be in accordance with the child support guidelines, unless
        the court finds that the guideline amount would be unjust, inappropriate, waived by the
        parties pursuant to a written agreement, or contrary to the best interest of the child or the
        parties. Standard forms to request a modification of child support shall be available from
        the Clerk of Circuit Court.
 WV Code �48-2-15, 48-2-15c, 48-2-15d, and �48A-2-17; and Rule 29, Rules of
        Practice for Family Law.
 The alimony provisions of a decree can be modified upon the request of either
        party, if the court finds that altered circumstances or needs of the parties require a
        modification to meet the ends of justice. The primary standard to determine whether or
        not a trial court shall modify an order awarding alimony is whether or not there has been
        a substantial change of circumstances.  WV Code �48-2-15.
 WISCONSINA judgment or Order for child support, maintenance payments, or family support
        payments may be modified upon a finding of a substantial change in circumstances. 
        Wis. Stat. �767.32.
 Upon 60 days written notice to the other parent, a parent with physical placement
        rights to a child may ask the court for approval to move the child�s residence out of the
        state, or more than 150 miles from the other parent but still within the state. Whether the
        request will be granted depends upon a number of factors, including the amount of time
        the parents have with the child under the prior court Order for physical placement rights.
        The court considers the following factors: 1) whether the purpose of the proposed action
        is reasonable;2) the nature of the child�s relationship with the other parent and the
        disruption to that relationship which may result; and 3) the availability of alternative
        arrangements to continue the child�s relationship with the other parent.
 Wis. Stat. �767.327.
 WYOMINGThe child support and alimony provisions in a decree can be modified upon a
        showing of changed circumstances since the entry of the decree. With respect to
        alimony, the court may from time to time, on the petition of either of the parties, revise
        and alter the award of alimony upon a showing of change in circumstances. 
        W.S. 20-2-116.
 With respect to an award of child support, the court may also modify a prior child
        support order upon a showing of changed circumstances. Application of the child
        support guidelines is encouraged to determine if a modification is appropriate. There is a
        rebuttable presumption that modification is appropriate when application of the
        guidelines would result in a 20% change in the monthly child support award. The court
        shall require the parties, in a modification motion, to complete a verified financial
        statement on the forms approved by the Wyoming Supreme Court. If, upon applying the
        presumptive child support pursuant to the guidelines, the court finds that the support
        amount would change by 20% or more per month from the amount of the existing order,
        the court shall consider this to constitute a change of circumstances sufficient to justify
        modifying the order.  W.S. 20-6-306.
