Yes he can. The birth certificate does not give him parental rights, only the court can when he presents the DNA result. But if the mother is in the picture it will be shared custody at the most unless she is unfit.
By law, the "father" is the man who signed the birth certificate unless/until paternity is established in some other way.
DNA testing can be done before or after a birth certificate is signed if there is any question about who the father of a child is or if visitation rights are being contested.
The father of the baby would have to sign his rights over as a parent as long as paternity has been established. If the father has not signed or been named on the birth certificate and can prove paternity (through DNA testing) or other means he has a legal right to his child.
Yes, but if you're not married to her, you have no rights to the child. see link
No, as he has no legal rights to the child even if he sign the certificate himself. You will need to file for custody. see links below.
No, paternity would need to be established, and even than, it is dependent on state laws. See related question
The child's last name isn't relevant. However, once you signed the birth certificate, you became the child's father until/unless a court rules otherwise and, yes, you could get visitation.
Helen Keller's birth certificate was signed by Dr. Thomas Hopkins, who was the attending physician at her birth.
he says i dont want your dam child
This is a legal question. In the United States there are 50 states plus other local administrative units. Each has its own rules concerning custodial rights.
yeah sure whatever homboyy
Yes, he is still the father. If you were married to the boyfriend and he adopted the baby you would still have to get the father to sign away his rights.
