(2) If a child was conceived by assisted reproduction under a gestational surrogacy agreement that does not comply with RCW 26.26A.705, 26.26A.710, and 26.26A.715, the court shall determine the rights and duties of the parties to the agreement consistent with the intent of the parties at the time of execution of the agreement.

(5) Except as otherwise provided in subsection (4) of this section, if an intended parent is determined to be a parent of the child, specific performance is a remedy available for:

(a) Breach of the agreement by a woman acting as a gestational surrogate which prevents the intended parent from exercising immediately on birth of the child the full rights of parentage; or
