Yes but he may have to prove paternity first.
A child's biological father can have his name added to a child's birth certificate regardless of whether or not the mother agrees to it. If the biological father voluntarily relinquishes his parental rights and the child is legally adopted by another man, his name can be added to the birth certificate in place of the biological father.
In all U.S. states the biological unwed mother is considered to have sole legal and physical custody of her child. If the biological father wishes to assert his parental rights he must first establish paternity to the child in question and petition the court for visitation privileges or custodial rights. If the mother wishes to pursue child support for the minor child she must show proof of paternity (signed birth certificate, or notarized affidavit for the father). It is the responsibility of the alledged father to prove he is or is not the biological father of the child, regarding custody, visitation and/or obligation of financial support.
If he can prove that he is the biological father of the child, he can seek custody or visitation rights, regardless of whether or not he is on the birth certificate or paying child support. In fact, if he is the biological father he can legally have his name added to the birth certificate. However, if he has not been around for 16 years, it is unlikely that a judge will grant anything more than visitation rights, and the child is old enough to have a say in whether or not they want visits from their father.
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.
Yes, you do. You fathered the child and now you need to pay for what you did. Accept the responsibility.
He has the right to petition the courts for a determination of paternity and, if he is the father, the right to pay child support and petition for visitation.
That is up to the courts and not the adoptive father.
yes biological fathers may seek visitation and custody rights
Oh yeah. The biological father and mother are put on the certificate.
Need to file a petition for visitation. If the father is the biological father he has a right to visitation. There is no court that will not grant visitation to a father. Unless it is proved in court that the father is unfit. There has to be proof of that.
Yes, but he will have to file a petition for visitation. He may also have to go through paternity testing to verify.
If you are adopted, your biological father has no legal standing. And there is no requirement that any parent sign a wedding certificate. If you are underage, you may need signatures to obtain the marriage license and it would be the adoptive parent that would have to sign.
