(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.
