My ex husband applied for government assistant, repeatly. I am ordered to pay child support. He is unemployed and cannot get a job because of a prior case against him. I want to know what can I do to gain custody and stop sending child support. I provide all of their needs without government assistance. DO I have a valid case against him and the state? (He applied for medicad, but I have them covered on my insurance. He also applied for TANF, and recieves food stamps.)
