A married employee or Member retiring under CSRS will receive a fully reduced annuity to provide a current spouse annuity unless—

The employee or Member, with the consent of the current spouse, elects a self-only annuity, a partially reduced annuity, or a fully reduced annuity to provide a former spouse annuity, in accordance with § 831.612(b) or § 831.614; or

The employee or Member elects a self-only annuity, a partially reduced annuity or a fully reduced annuity to provide a former spouse annuity, and current spousal consent is waived in accordance with § 831.608.

Qualifying court orders that award former spouse annuities prevent payment of current spouse annuities to the extent necessary to comply with the court order and § 831.614.

The maximum rate of a current spouse annuity is 55 percent of the rate of the retiring employee's or Member's self-only annuity if the employee or Member is retiring based on a separation from a position under CSRS on or after October 11, 1962. The maximum rate of a current spouse annuity is 50 percent of the rate of the retiring employee's or Member's self-only annuity if the employee or Member is retiring based on a separation from a position covered under CSRS between September 30, 1956, and October 11, 1962.

The amount of the reduction to provide a current spouse annuity equals 21/2 percent of the first $3600 of the designated survivor base plus 10 percent of the portion of the designated survivor base which exceeds $3600, if—

The employee's or Member's separation on which the retirement is based was on or after October 11, 1962; or

The reduction is to provide a current spouse annuity (under § 831.631) for a spouse acquired after retirement.

The amount of the reduction to provide a current spouse annuity under this section for former employees or Members whose retirement is based on separations before October 11, 1962, equals 21/2 percent of the first $2400 of the designated survivor base plus 10 percent of the portion of the designated survivor base which exceeds $2400.
