My baby's daddy has made no attempt or effort at being a father. He is more interested in seeing me personnally than our child. He wants to give up all his parental rights, which I think would be a good idea. However I still need child support to help with daycare costs because I am a single mom. In Kansas, can a father relinquish his rights and still be liable for child support?

If you read the many other threads that ask this same question you would see the answer is rights and responsibilities are two separate things. So the answer is no, giving up parental rights does not relieve one of the responsibility for support.

I am sure your baby daddy believes it means no child support, if you read the 1000's of questions we get here, you will see most men believe this.

So once he finds out he still has to pay, I doubt he will want to go to the expense and trouble of giving up his rights.
