Thank you for contacting us at JA for guidance.
You will need to look to the original divorce decree to find out exactly what each of you are responsible for. If your ex-wife has violated the decree in some way, you will need to file a motion for contempt in the court where your divorce and decree were entered. If your ex-wife has primary custody, she can claim the children on her tax return. If you have both moved, you may have the judgment registered where you live and file your motion in your local court.
It also appears that you are wanting to file a motion to modify the custody of your children. The court will consider many factors, amounting to the best interests of the children in determining who should have primary physical custody. If the children are in their teens, their desire to live with one parent over another does carry weight with the court, but is not the deciding factor.
