(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.

(2) Except as otherwise provided in subsection (3) of this section or section 19-4.5-112, neither a gestational surrogate or genetic surrogate nor the surrogate's spouse or former spouse, if any, is 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.

(4) Except as otherwise provided in subsection (3) of this section or section 19-4.5-110 (2) or 19-4.5-112, if, due to a clinical or laboratory error, a child conceived by assisted reproduction under a surrogacy agreement is not genetically related to an intended parent or a donor who donated to the intended parent or parents, each intended parent, and not the gestational surrogate or genetic surrogate and the surrogate's spouse or former spouse, if any, is a parent of the child, subject to any other claim of parentage.

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