Court Ordered DNA Test and Where to Get Them Done.

Is he listed on the Birth Certificate?

Was there a Recognition of Parentage ("ROP") Form filled out when the child was born, since they were not married?

He can not stop her from going anywhere at this point unless there is papers filed with the court.

How old is the child and has he tried to be a part of the sons live since he was born?

He will need to file a Motion with the county before he can do anything legally from stopping her. Unless I know that exact situation, it's hard to give advice. So if he has done nothing as far as paperwork, he would start with a Motion for Paternity and than go from there.

If he's on the birth certificate, I'm pretty sure he has rights. If he's not, then he has to request a paternity test and pay for it.

He needs a lawyer and a custody agreement asap. He has the same rights as any father who was married to the mother. Father is father, it doesn't matter about marital status.

Once a custody agreement is in place, in most states you can't move with a kid unless each party agrees - she CAN'T just take him and leave if the father is involved, paying support etc. (unless there are extenuating circumstances and then a judge could let her leave). And even then he should get visitation. My daughters dad actually has MORE days of visitation since I have moved out of state - we split the cost of tickets and fees.

Why does he only have supervised visits? How old is the kid? How involved has he been and how involved does he want to be (ie keeping her from moving if he's only going to see the kid once a month or every couple of months is very different than if he is going to try for every weekend or every other weekend etc)? Does he currently pay child support? All of these are things that the lawyer will help him sort out. (FYI - support and visitation are 2 completely different things, but if no custody arrangement is currently in place and he has been paying support it will look better for him. So, he should bring documentation of any money he has paid the mom).

Good luck.
