The following rules apply in a proceeding to adjudicate a presumed parent’s parentage of a child if the person who gave birth is the only other person with a claim to parentage of the child:
(1) If no party to the proceeding challenges the presumed parent’s parentage of the child, the court shall adjudicate the presumed parent to be a parent of the child.
(2) If the presumed parent is identified under subsection 604(a) of this title as a genetic parent of the child and that identification is not successfully challenged under said subsection, the court shall adjudicate the presumed parent to be a parent of the child.
(3) If the presumed parent is not identified under subsection 604(a) of this title as a genetic parent of the child and the presumed parent or another party challenges the presumed parent’s parentage of the child, the court shall adjudicate the parentage of the child in the best interests of the child, based on the factors listed in subsections 206(a) and (b) of this title. Challenges regarding the parentage of a child born through assisted reproduction must be resolved under chapter 7 of this title.
