Hello I'm asking on how to sign my right away I am the father and I don't get to see my kids much and have to pay a lot of money for childsupport which I'm behind on and now they want to thow me in jail when I'm trying. So I would like to just sign my rights away. She is married now and my kids have his last name and she always says they don't need me as a dad they have a dad. So please help me all she wants is to see me in jail.

You would need to go to court to sign away your rights, but you need to understand that unless her new husband adopts those children, you are STILL liable for child support.

Giving up your rights does not mean you can give up your obligations.

Sign away -- you will still be paying child support though unless he adopts them -- they are your kids SUPPORT them. Savage

As you most likely have figured out by now, signing away your "rights" merely mean you can't visit, can't have any say about the life of your child, but it does not stop your obligation to pay child support ( if you could give that away would people be sitting in jail? ) only if a step parent wants to adopt, will the child support end.
