If there is a final order signed, there are only a few ways to undo it. It can be modified if the court finds it is in the child's best interest but the father would have to file a new lawsuit and show grounds to change it. If the order is less than 30 days old, the father can file a motion for new trial but he has to show the result did not follow the law or some other reason. Every child support payment not made is a judgment by operation of law so they cannot be waived. Good luck.
