The other parent of my child is not following our custody decree. How do I make the other parent comply?
To enforce the custody (legal decision making and parenting time) decree, you may file a petition for enforcement, or you may start a contempt proceeding with an order to show cause or order to appear, depending on the situation. The court might have a do-it-yourself packet to enforce the decree that includes instructions and forms. If not, ask if the court accepts the Maricopa County forms. Some courts offer programs, such as counseling, or require additional steps, like mediation.
