I have been fighting my disability case for the past 5 years. In that time my ex wife was a bit understanding about payments. I finally won and I started getting disability benefits. I give her money every month from that, she and I talked about it and decided to close the case. We both talked to our worker and signed the paperwork that agrees to close the case it was submitted to a judge he signed it. I received a letter telling me it was closed out and all back child support was at zero. This Thursday a new worker called me telling me they made a mistake and I still got to pay all back child support. My question is if the judge closed the case and I got the documents that read that do I have to pay or do I fight it?
