(ii) Upon OPM's receipt of a claim for an annuity authorized for unremarried widows and widowers by section 2 of the Civil Service Retirement Act Amendments of June 25, 1958, 72 Stat. 218.

(2) A former spouse annuity begins to accrue—

(i) For annuities under §831.683, on the later of the day after date of death of the retiree or the first day of the second month after the date the application for annuity is received in OPM; or
