Unless a gestational carrier agreement expressly provides otherwise:
(1) the marriage of a gestational carrier or of an intended parent after the agreement has been signed by all parties does not affect the validity of the agreement, the gestational carrier’s spouse’s consent or intended parent’s spouse’s consent to the agreement is not required, and the gestational carrier’s spouse or intended parent’s spouse is not a presumed parent of a child conceived by assisted reproduction under the agreement; and
(2) the divorce, dissolution, annulment, or legal separation of the gestational carrier or of an intended parent after the agreement has been signed by all parties does not affect the validity of the agreement.
