Can I file for a change of custody inone stateif my divorce was finalized in another?

Under the The Uniform Child Custody Jurisdiction Act (UCCJEA), the Full Faith and Credit for Child Support Orders Act (FFCCSOS), and the Uniform Interstate Family Support Act (UIFSA), the state issuing a child support order retains continuing and exclusive jurisdiction over its child support orders so long as the child continues to reside in the issuing state.  Therefore, the court that makes an initial custody determination has jurisdiction over that determination unless the child does not presently reside in the issuing state.

If the children do not still live in the original state, the question of where to modify the order depends various criteria. For example, a state may modify another state court custody ruling if:

• The state is the child's new home state (and valid residency has been established);
• Jurisdiction is declined by the issuing state;
• All courts having jurisdiction have deferred to another state; or
• No court of any other state would have jurisdiction (e.g.in the case of foreign country custody order).

Clearly, depending on the facts of a particular case, this can be a technical and complex area of the law.  You should consult directly with a family law attorney about your situation.  However, bottom line, you will probably have to modify the custody order in MI if that is where your children still reside.
