The general procedure is:
1. File a "petition for a determination of arrears and entry of money judgment."
2. After the court determines the total arrears and enters the money judgment into the court docket, you would make your payment to the supported parent, who would sign a "satisfaction of judgment" which you could then file with the court. That would terminate your obligation on the money judgment and eliminate the arrears.
3. Unfortunately, while there is an official court form providing the language of the order itself (click here) -- there is no official court form for the petition to request that the court determine arrears and enter the money judgment. Consequently, you would either have to draft the petition and affidavit from scratch, find an applicable template in a law library, or hire a lawyer to draft the petition for you.
That's about as far as I can go in this forum, because I cannot practice law here and draft the petition for you (illegal and a violation of website rules, as Justanswer, LLC is not a law firm). If you need assistance to find a lawyer or a law library, please let me know and I'll be happy to try to provide further information.
I hope I've answered your question. Please let me know if you require further clarification. And, please provide a positive feedback rating for my answer (click 3, 4 or 5 stars) -- otherwise, I receive nothing for my efforts in your behalf.
Thanks again for using Justanswer!
