Okla. Stat. tit. 10, § 557.12
B. Upon receiving notice of the birth, the court shall render an order that:
D. If a person alleges that a child born to a gestational carrier:
2. Is a genetic child of the gestational carrier or the gestational spouse, such that either the gestational carrier or the gestational spouse made a genetic contribution to any gamete from which the child was conceived or the embryo from which the child was grown,
the court shall order that scientifically accepted parentage testing in compliance with Oklahoma law be conducted to determine the child's parentage. If the court determines that any of the allegations in paragraph 1 or 2 of this subsection are true, the Oklahoma Gestational Agreement Act shall not apply and the parentage, rights and obligations of the parties and the child shall be determined as otherwise provided by Oklahoma law. Any action related to such allegations may only be brought within one hundred eighty (180) days after the birth of the child and not afterward. The preceding sentence shall be interpreted as a statute of repose and not as a statute of limitations.
