Section 27-210-35-103 - Changing the Optional Benefit Payment Plan before Receipt of a Retirement Benefit

No change in the option selected shall be permitted after the member's death or after the member has received a retirement benefit except as provided in Section 104. This prohibition extends to a member's option to receive a refund of the amount of accumulated employee contributions and interest in lieu of receiving a retirement benefit. For purposes of this Regulation, "receipt of a retirement benefit" means negotiating or cashing a benefit payment. Except as specifically provided by law, a member may not change an option after 90 days from the date the first benefit payment is issued even if such payment is not negotiated or cashed.
