Ok i know to the eye of the law she is not my step daughter. Ok so your saying that the guy who got her preg who has been out of the picture and is not on the Birth Certificate must give consent even so he prettty much is not in the picture and has no contact with ether the mother or child? Also what do you mean by paternity?

Again, please have you girlfriend hire counsel. This forum is not designed to teach people the law, but merely to give advice.
