Hi my name is Tosha and I have a 9 month old daughter. Her bio- father has been out of the picture for over six months. He is not on her birth certificate. My fiancée wants to adopt her, but we don't want her bio- father to try to come back into the picture out of spite to me. What can I do? Can my fiancée adopt my daughter without the bio- father signing over his rights? Could he come back into her life after she is adopted?
