California Code, Government Code - GOV § 21635

Notwithstanding any other provisions of this part, survivor continuance allowances payable to surviving spouses upon death after retirement of a member do not cease upon remarriage if the remarriage occurs on or after January 1, 1985, in the case of local members of contracting agencies that elected to be subject to this section, or all members on or after January 1, 2000. However, pursuant to Section 22822, the surviving spouse may not add the new spouse or stepchildren as family members under the continued health benefits coverage of the surviving spouse. The survivor continuance allowance shall be restored if that allowance has been discontinued upon the spouse's remarriage prior to January 1, 2000.
