As noted, here and a serveral times a day, first remember giving up your rights, is not giving up your obligation, so unless the mother of the child gets remarried, and the new parent wants to adopt, you can't give up paying child support.

So basically the mother of the child will be bothering you for the next 18 years at least for money. So if that is the bother, get used to it.

Next you don't have to visit, you don't have to do anything but pay child support.
