[§584A-602]  Adjudicating parentage of child with presumed parent.  (a)  A proceeding to determine whether a presumed parent is a parent of a child may be commenced:

     (1)  Before the child becomes an adult; or

     (2)  After the child becomes an adult, but only if the child initiates the proceeding.

     (b)  A presumption of parentage under section 584A-303 cannot be overcome after the child attains two years of age unless the court determines:

     (1)  The presumed parent is not a genetic parent, never resided with the child, and never held out the child as the presumed parent's child; or

     (2)  The child has more than one presumed parent.

     (c)  Except as otherwise provided by law, the following rules shall apply in a proceeding to adjudicate a presumed parent's parentage of a child if the individual who gave birth to the child is the only other individual 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 section 584A-705 as a genetic parent of the child and that identification is not successfully challenged under section 584A-705, the court shall adjudicate the presumed parent to be a parent of the child; and

     (3)  If the presumed parent is not identified under section 584A-705 as a genetic parent of the child and the presumed parent or the individual who gave birth to the child challenges the presumed parent's parentage of the child, the court shall adjudicate the parentage of the child in the best interest of the child based on the factors under sections 584A-607(a) and 584A-607(b).

     (d)  If in a proceeding to adjudicate a presumed parent's parentage of a child, another individual in addition to the individual who gave birth to the child asserts a claim to parentage of the child, the court shall adjudicate parentage under section 584A-607, unless a valid denial of parentage is filed in accordance with section 584A-608.
