Can my husband sign my son birth certificate even though he is not the father? My childs real father has not been in the picture since I was five months pregnant because he was abusive. My husband has been there for my son since he was 4 months old and now he is 7. I heard that it is legal for a man to sign a birth certificate and that the state of Georgia would reconize him as the father if the real father does not come forward. Is this true?
