Should I still pay child support if I am disabled and my social security is garnished every month?

I do not understand. You are on muting some facts. If there are no minor children there should be no support unless it is past due arrears. Your children have to eat, whether you are on disability or not. Hire an attorney to look into the issues.

You do not want to stop your payments on your own accord for you risk being held in contempt of a Court Order and that will result in either fines or potentially even jail time. Instead you may want to petition the court for a modification on the child support order if anything about your income is different now than it was when the order was entered. The Court will look and you income, and if they determine that you cannot afford to pay what you are currently paying, they may, at least, reduce your payments.
