(1) An EDRO may provide for the payment of a benefit to an alternate payee beginning on or after the participant‘s earliest retirement date but before the participant terminates employment as provided in this section. An alternate payee shall begin to receive the payment of a benefit under this section effective the first day of the month immediately following the month in which the alternate payee notifies the retirement system of his or her election to begin to receive payment of his or her interest in the benefit of a participant.

  (2) If an alternate payee elects to receive his or her interest in the benefit of a participant after the participant’s earliest retirement date but before the participant’s termination of employment, the alternate payee is only entitled to the actuarial equivalent of the alternate payee’s share of the participant’s benefit that would be payable when the participant reaches age 60. If the participant retires before age 60, the retirement system shall recalculate the benefit payable to the alternate payee so that the recalculated benefit payable to the alternate payee plus the benefit previously paid to the alternate payee are the actuarial equivalent of the alternate payee’s share of the benefit payable to the participant. If the recalculated benefit is more than the benefit the alternate payee is receiving, the retirement system shall begin paying the recalculated benefit to the alternate payee effective the first day of the month immediately following the month in which the participant retires.
