A DNA test can prove if the biological father is actually the father. If it is proven he is the father, then he should have all parental rights as any other parent.
He would have all of the rights that a biological father has. If he was not the biological father, then his name should not have been put on the birth certificate in the first place, unless he adopted her and the birth certificate was changed.
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.
Get a lawyer. You have a couple of ways to assert your parental rights.
If you're in the US, he has the same rights as any other father, because he is the legal father (biological is irrelevant at this point).
only if he can prove that he is indeed prove that he is 99.9% the father
no, changing the birth certificate requires adoption, and can only be done if the birth father's parental rights have been terminated.
he says i dont want your dam child
If the father wants custody rights, this would be usable in court.
Is he actually the father, or are you planning to commit paternity fraud?
If it's established who the biological father is, regardless what name is on the birth certificate, he will have to give up his parental rights in order for someone else to adopt the child. He can also go to court and have the name on the birth certificate changed to his.
The are not always list yet still have court ordered rights.
The same if he is listed on the birth certificate. NONE
