My nephew and his ex-girlfriend have a 1 1/2 year old child. The child has his last name and his name is on the birth certificate. He was there for the birth but they have not been together as a couple since she was pregnant. He has been paying her weekly support, WITHOUT A COURT ORDER. They have never been to court. The child's mother has been very strict about any visitation of the child, the father has never been allowed to have the child overnight even. Now the mother has married and is pregnant. She wants to take my nephew's child and move out of state. What are his rights and what does he need to do legally?
