This is fairly common. You need to petition child support enforcement in IL. If they will not work with you over the phone, you are going to need to file certain motions in court. If you are paying back the state for arrears, then you are going to have to finish. In the end, this is probably not something you are going to be able to handle unless you are well versed in IL child support enforcement regulations. You should post this question in the IL forum and hire the attorney that provides you with the best answer.
