I’m 18, and would like my step father to adopt me. Me being 18, does my biological father still have to give consent?

The birth parents do not have to consent to the adoption but they must be given notice of the action, unless they are deceased. The law states, “When petitioner seeks to adopt a person who is eighteen years of age or older, only the sworn, written consent of the person sought to be adopted shall be required and no order of reference or any home studies need be issued."
