How child support arrearages are handled varies from county to county. Your boyfriend should plan on having proofs with him regarding his recent employment history and a plan to present to the Friend of the Court for repayment of the arrearage. Generally, as long as he is working and paying, the outcome should be satisfactory. However, it is a legal proceeding, and he would do well to consult with and retain a local family law attorney familiar with the Friend of the Court and able to assist him in working out a payment plan.

You should expect that in addition to your boyfriend continuing to pay the court ordered child support, he will also be court ordered to pay an amount certain each month toward his arrearage just as you say he has been paying extra since he became employed. He is being proactive which is good and should help his case.
