Each participant shall file with the administrative service agency a written designation of one or more persons as the beneficiary who shall be entitled to receive the plan benefit, if any, payable under the plan upon his or her death. A participant may from time to time revoke or change his or her beneficiary designation without the consent of any prior beneficiary by filing a new written designation with the administrative service agency. The last such designation received by the administrative service agency "in good order" shall be controlling; provided, however, that no designation or change or revocation thereof shall be effective unless received by the administrative service agency in good order prior to the participant's death, and in no event shall it be effective as of a date prior to such receipt. For purposes of this Article
IX, a beneficiary designation shall be deemed to be received in good order only if the administrative service agency can reasonably identify the beneficiary or beneficiaries named in the designation.
Notwithstanding § 50-9.2, a beneficiary who is a surviving
spouse of the participant may designate a subsequent beneficiary,
subject to the same filing requirements of § 50-9.1, to
the extent permitted under Section 401(a)(9) of the Code. To the extent
such surviving spouse is not permitted or does not elect to designate
a subsequent beneficiary pursuant to the preceding sentence, and the
surviving spouse dies prior to receiving a complete distribution of
the amount that would have been paid to such surviving spouse had
such surviving spouse's death not then occurred, then, for purposes
of the plan, the distribution that would otherwise have been received
by such surviving spouse shall be paid to the surviving spouse's estate.
