Each state will require certain procedures to make a name change. In most states a state court will oversee the procedure. In general many states will require paperwork for a name change so please consult an attorney before making a name change. Typically a name change will require some of the following documents:

Birth Certificate

A Petition for Change of Name

A Decree Granting Change of Name

In some cases public notification may be needed, in which an advertisement is posted in a local paper showing that the individual has applied for an intended name change.
