Is he the child's biological father? If so, he does have rights and he would have to sign the papers, unless he previously signed a waiver terminating his parental rights.
Even if no custody and access orders are in place, the father has up to six months to file an injunction ordering the return of the child to the jurisdiction of the court.
What is the question?
If he is legally the father he has a chance, of course. It's up to the judge. He has to petition the court for custody.
Yes. For the father to get legal custody he has to go to court and petition for it after he has proved paternity. If he has had the child for the past 18 months, this should not be a problem.
No, 3 months is not long enough for them to remove parental rights.
Yes, but he has up to six months to file an injunction ordering the child be returned to the jurisdiction of the state/county. I teach fathers how to do this.
No, as it's been longer than six months

the father should file for custody
You can try taking him to court. This does not mean that you will get full custody.
Only if the mother can prove repeatedly that the father is not responsible.Our custody case is in FL and our lawyer told us that when my husband deploys with the military that his children can remain in our home and do not have to relocate to the mother's home for the 6 months he will not be there.
Six months, but the father can file in NH first.
