Can your boyfriend adopt your 16-year-old daughter and place his name on her birth certificate without the consent of the child's biological father?
The biological father would have to voluntarily relinquish his rights or the court would have to terminate his parental rights to the minor child before the child could be adopted by anyone.
FYI, in most cases the "boyfriend" could not adopt the minor child even if the biological father were to give up his parental rights. The mother of the child and her significant other generally have to be legally married before the court would allow an adoption to proceed. This mostly depends on whether your state recognizes your union in some way (some sort of civil union). Occasionally, some odd exceptions are granted (in Alaska, there was a petition where a 3rd person wanted to legally adopt a child, and the court granted it)
My husband is not my daughters biological father yet his name is on her birth cert and we are now getting divorced What rights does he have to my daughter?
Can mother get a restraining order on her daughters boyfriend if both the daughter and the boyfriend are eighteen?
When I had my daughter, her father was not able to be there at the time, so I was the only one to sign the birth certifiate as a parent. The father's name can be added by the father at a later date if that is what either of you wants to do. No one but the biological parents can sign a birth certificate.
