A participant, former participant, or retired participant in the system who on November 15, 1982, had a former spouse may, by a spousal agreement, elect to receive a reduced annuity and provide a survivor annuity for such former spouse under section 2032(b) of this title.

If the participant or former participant has not retired under such system on or before November 15, 1982, an election under this section may be made at any time before retirement.

(1) If the participant or former participant has not retired under such system on or before November 15, 1982, an election under this section may be made at any time before retirement.

(2) If the participant or former participant has retired under such system on or before November 15, 1982, an election under this section may be made within such period after November 15, 1982, as the Director may prescribe.

(3) For the purposes of applying this subchapter, any such election shall be treated in the same manner as if it were a spousal agreement under section 2094(b) of this title.

An election under this section may provide for a survivor annuity based on all or any portion of that part of the annuity of the participant which is not designated or committed as a base for a survivor annuity for a spouse or any other former spouse of the participant. The participant and the participant’s spouse may make an election under section 2031(b)(1)(B) of this title before the time of retirement for the purpose of allowing an election to be made under this section.

Such reduction shall be effective as of—

(1) Computation The amount of the reduction in the participant’s annuity shall be determined in accordance with section 2031(b)(2) of this title.

Such reduction shall be effective as of—

(A) the commencing date of the participant’s annuity, in the case of an election under subsection (b)(1); or

(B) November 15, 1982, in the case of an election under subsection (b)(2).
