(a) An intended parent who is a party to the agreement may terminate the agreement at any time before a gamete or embryo transfer by giving notice of termination in a record to all other parties.

The notice of termination must be attested by a notarial officer or witnessed.

(b) A woman acting as a genetic surrogate who is a party to the agreement may withdraw consent to the agreement any time before forty-eight hours after the birth of a child conceived by assisted reproduction under the agreement. To withdraw consent, the woman acting as a genetic surrogate must execute a notice of termination in a record stating the surrogate's intent to terminate the agreement. The notice of termination must be attested by a notarial officer or witnessed and be delivered to each intended parent any time before forty-eight hours after the birth of the child.
