My ex-boyfriend does not want to pay child support, and he has a document sign by me that I will never ask for any child support from him, what do I do? Can he use that piece of paper signed by me not to pay? Am I in trouble :( he left me when he found out I am pregnant, I was so mad before he left I asked him never to show me his face again. :mad:

Have you taken him to court?

That document could hold up in court. You could claim it was made under duress. You need an attorney!

Generally-the child support is not for the mother,the child support is for the child:)
If the child needs of support it does not matter what you signed before.I believe there is no a judge who will reject to award child support only because the mother signed something.:)
