Gov. Code, § 21293

(a) The nonmember who is awarded a separate account may redeposit accumulated contributions previously refunded to the member in accordance with the determination of the court required by Section 21290.

(b) The nonmember may redeposit only those accumulated contributions that were previously refunded to the member and that the court has determined to be the community property interest of the nonmember in the accumulated contributions.

(c) If the nonmember elects to redeposit, he or she shall repay the accumulated contributions pursuant to Section 20750 or Section 20752.

(d) An election to redeposit shall be considered an election to repay all accumulated contributions previously refunded that the nonmember is entitled to redeposit.

(e) The right of the nonmember to redeposit is subject to the regulations of the board.

(f) The member has no right to redeposit the share of the nonmember in the previously refunded accumulated contributions unless the nonmember has permanently waived all rights in the system by effecting a refund of accumulated contributions pursuant to Section 21292. However, any right to redeposit previously refunded accumulated contributions not explicitly awarded to the nonmember by the judgment or court order shall be deemed the exclusive property of the member.

(g) If the nonmember elected to redeposit upon retirement and has subsequently died, prior to completing the redeposit, the board shall file a claim against the estate of the decedent to recover benefit payments that exceeded those for which payment was made.
