N.D. Cent. Code § 54-52.6-11: Refund beneficiaries

A participating or former participating member may nominate one or more individuals as a refund beneficiary by filing written notice of nomination with the board. If the participating member or former participating member is married at the time of the nomination and the participant's spouse is not the refund beneficiary for one hundred percent of the account, the nomination is not effective unless the nomination is signed by the participant's spouse. However, the board may waive this requirement if the spouse's signature cannot be obtained because of extenuating circumstances.
