(b) The nonmember shall file an application on a form provided by the system to obtain the refund. (c) The refund shall be effective when the system deposits in the United States mail an initial warrant drawn in favor of the nonmember and addressed to the latest address for the nonmember on file with the system. (d) The nonmember is deemed to have permanently waived all rights in the system and all rights to any future retirement benefits pertaining to the service credit accumulated contributions, or both, when the refund becomes effective. (e) The nonmember may not cancel a refund once it has become effective. (f) The nonmember shall have no right to elect to redeposit the refunded accumulated contributions from the nonmember’s account after the refund is effective, and shall have no right to redeposit or to purchase service credit after the refund becomes effective. (g) If at the time of the marriage dissolution or legal separation, the member does not have the necessary minimum credited service to elect deferred retirement, the nonmember shall receive a refund of the accumulated contributions and credited interest placed in the nonmember’s account. (h) If the nonmember receives a refund under this section, the member may elect to redeposit accumulated contributions and interest refunded to the nonmember and to receive credit for the service time that had been forfeited by the nonmember.
