Can a judge order me to return child suppost arrears

Hi First the burden is on your ex to prove that support collection seized too much money from him.  That's not your problem.   Second there's a real question about whether he can recoup any monies paid toward child support, particularly since he's been a deadbeat.   Question:  was there interest added to the judgment?  If so, that may explain the additional sums he's claiming he didn't owe. I would appear in Court and tell the judge that you've been running after this guy for 10 years, that support collection has been collecting, that the sums were insufficient to cover his obligation and that you've been having to make due on a lot less than he was supposed to pay.  What happens going forward also?   Is he going to pay?  Does he owe you money already?  My position would be that, with a guy who has been irresponsible, you need to make sure that there are sufficient monies coming in to provide for your child in the future.   I would hope that a judge would look at his history and reject his position. It also depends on the amount of the overage he's claiming was seized from him.   If it's alot of money, a judge may feel that such a windfall to you is not justified and the judge may order that he gets back part of it.  But, again, it's up to support collection to iron this out with your ex -- and it's not your responsibility. Good luck
