Unless the member is required by division (C) of this section to select a specified plan of payment, a member may elect a plan of payment as provided in division (B)(1), (2), or (3) of this section. An election shall be made at the time the member makes application for retirement and on a form provided by the public employees retirement board. A plan of payment elected under this section shall be effective only if approved by the board, which shall approve it only if it is certified by an actuary engaged by the board to be the actuarial equivalent of the retirement allowance calculated under section 145.33, 145.331, 145.332, or 145.335 of the Revised Code.
Consent shall be valid only if it is signed, in writing, and witnessed by a notary public. The board may waive the requirement of consent if the spouse is incapacitated or cannot be located or for any other reason specified by the board. Consent or waiver is effective only with regard to the spouse who is the subject of the consent or waiver.
The total amount paid as a lump sum and a monthly benefit shall be the actuarial equivalent of the amount that would have been paid had the lump sum not been selected.
The plan elected under this division shall become effective on the date of receipt by the board of an application on a form approved by the board, but any change in the amount of the retirement allowance shall commence on the first day of the month following the effective date of the plan.
