I would have to review the judgment of divorce and its provisions. Generally, at least in Michigan, a sole legal and physical custody parent, regardless of the fact that they have a legal right to do so, must seek the permission and provide notification to the court that they are removing the children from the state where the court has jurisdiction. This is normally a formality, but a necessity. If you have already moved you should file a motion with the court to at least inform the court of the current situation.
