The father's consent to the adoptions is not necessary if
1.
he is not a "presumed" father, his relationship has not been determined by a court, or he is not the legitimate father of the child; or
2.
he voluntarily relinquished the child for adoption, then the mother shall file a petition to terminate his parental rights.
