(a)
An option elected under Section 24300, 24300.1, or 24307 may be canceled by a retired member if the option beneficiary is the retired member’s spouse or former spouse and a final decree of dissolution of marriage or a judgment of nullity has been entered or an order of separate maintenance has been made on or after January 1, 1978, by a court of competent jurisdiction. A retired member may cancel the option before or after issuance of the first retirement allowance payment.
(b)
The retired member shall notify the board in writing of cancellation of the option. Notification shall not be earlier than the effective date of the decree, judgment, or
order and shall include a certified copy of the final decree of dissolution, or judgment of nullity, or an order of separate maintenance, and any property settlement agreement.
(c)
Upon notification to the board, the retired member may elect: (1) to receive the unmodified retirement allowance from the date of receipt of the notification; or (2) a new joint and survivor option under Section 24300.1 and may designate one or multiple new option beneficiaries. Modification of the retirement allowance because of the newly elected option or newly designated beneficiary or beneficiaries shall be based on the ages of the retired member and the new option beneficiary or beneficiaries as of the effective date of the new option. The election of a new joint and survivor option or the designation of a new option beneficiary or beneficiaries shall be
consistent with the final decree of dissolution, judgment of nullity, order of separate maintenance, or property settlement agreement, and shall not result in any additional liability to the Teachers’ Retirement Fund. The effective date of the change shall be the date notification is received by the board.
