“He won’t give up his rights to a child that he’s have no contact with in or over six years. He has no part her life at all. I’m in the state is Wisconsin.”
In some states you are at your option to bring an action for “termination of parental rights”. Check with a local attorney if you can voluntarily bring such an action. Is he paying his support? Some jurisdictions would allow the support collection agency to bring such an action.
Some people cannot be reasoned with just to give up their rights towards their children, not matter how difficult you make it for them to be a parent to that child. Sometimes it takes a judge.
