Can the Child in a Child Support case collect the Arrears in a case.

I am the child in the child support case and I am attempting to collect the arrears owed by my father. Both my father and mother are no longer in the picture, I have been told by a couple of people that it is not possible, but I was told by the Attorney Generals Office that case was established at that it is. I just need a lawyer. I am looking for someone that can represent me. So my question is. Is it possible and if so who should I contact for the best results?
