My children's father was ordered to pay child support in 1992. I have giving him a one time credit of $500 about 17 years ago and that was because he did pay some but I was not for sure exactly how much. He has not paid any monies to me since then except for a $100 purge last month. He is in the arrears of approximately $75,000. He is now receiving SSDI and is suppose to be getting back pay from the time he applied,I am just not to sure of the time that he applied. I am not even sure if he has received any of this back pay. I have contacted child support but I have no idea of what is going on at this time. Child support office is way to hard to talk to anyone. Am I entitled to any?
