parental rights relinquished/ back child support?

What is the name of your state?

Kansas, boyfriend recieved letter in mail from ex-wife with copy of his son's birth certificate changing the last name to current husband's stating that "unlike your name, the back child support for 7 years did not go away". First off paternity was never established his name was on the birth certificate she has been in hiding for the last seven years so he couldnt have contact with them and child support was never established in a court of law unless he was never informed. what can he do?

first off, dna needs to be taken. no child support can be taken from him unless dna was established. now, if the ex purposely took him to court for dna/cs and purposely made sure he never got the papers, then yes, a judgement can be made and probably was made by default. so there fore cs is in effect. first, contact the court where the judgement came from, tell them the correct address. ask them who you can talk to about the case, tell them the mothers name, ask when the case was filed, what date, what address was the papers sent to? ask what was the judgement, ask can they send you the original papers that you never got, ask them to send you the judgement that you never got. after you get all of these things, file a motion to get the mother in court, do a motherless dna, and go from there. these days, if the father didn't sign the bc, the mother can't put the fathers name on it herself, its now against the law. and the acknowlegement of paternity wasn't signed so he's fine. i take it he's never seen the child? she can go to jail for stuff like this. play hardball, let her get away with nothing.
