(1) Except as otherwise provided in subsection (3) of this section or section 19-4.5-110 (2) or 19-4.5-112 , on birth of a child conceived by assisted reproduction under a surrogacy agreement, each intended parent is, by operation of law, a parent of the child.

(3) If a child is alleged to be a genetic child of the individual who agreed to be a gestational surrogate, the court shall order genetic testing of the child. If the child is a genetic child of the individual who agreed to be a gestational surrogate, parentage must be determined based on article 4 of this title 19.

(5) A donor is not a parent of a child conceived by assisted reproduction.
