(a) At any time after a qualified domestic relations order is filed and approved by the system, the alternate payee may withdraw in a lump sum the accumulated contributions attributable to the interest awarded to the alternate payee by the qualified domestic relations order.
(b) The alternate payee may commence a life annuity calculated in accordance with the terms of the plan and based on the interest awarded to such alternate payee at such time when the participant:
  (1) is eligible to retire;
  (2) commences a disability retirement;
  (3) dies and was eligible for a survivor death benefit under §844.407 of the Government Code; or
  (4) has attained the age at which the participant would have been eligible to retire, if the participant withdrew his or her account and was vested at the time of withdrawal.
(c) An alternate payee may commence an annuity under subsection (b)(1) of this section even if the participant has not retired or under subsection (b)(4) even if the participant is not eligible for an annuity benefit.
(d) If the participant dies before commencing a benefit, and the participant was eligible for a survivor annuity under §844.407 of the Government Code, then the alternate payee may commence an annuity under subsection (b)(3) or withdraw the accumulated contributions awarded under the qualified domestic relations order.
(e) If the participant dies before commencing a benefit, and the participant was not eligible for a survivor annuity death benefit under §844.407 of the Government Code, then the alternate payee may withdraw the accumulated contributions associated with the interest awarded under the qualified domestic relations order.
(f) The alternate payee must commence a distribution when the participant attains age 70 1/2 or when the alternate payee attains age 70 1/2, whichever is earlier. If the participant is still a depositing member and not vested, then the alternate payee is not required to commence an annuity or take a withdrawal. If the participant is vested when a mandatory distribution is required, the alternate payee is eligible for an annuity benefit.
(g) If the alternate payee dies before commencing a benefit, and the participant is eligible for a survivor annuity benefit under §844.407 of the Government Code or has commenced a disability retirement, then the alternate payee's beneficiary must commence a survivor annuity pursuant to §844.407 that is actuarially equivalent to the deceased alternate payee's benefit awarded under the qualified domestic relations order.
(h) If the alternate payee dies before commencing a benefit and the participant is not eligible for a survivor benefit under §844.407 of the Government Code, then the alternate payee's beneficiary is eligible for a benefit equal to the accumulated contributions awarded to the alternate payee at the time of the alternate payee's death.
(i) If the alternate payee dies after commencing a life annuity, then the alternate payee's beneficiary may be eligible for a lump sum payment equal to the difference of the aggregate annuity payments made to the alternate payee, less the accumulated contributions associated with the interest awarded to the alternate payee, if any. If no valid beneficiary exists, or if the alternate payee dies without having a designated valid beneficiary, the benefit that would have otherwise been payable to the beneficiary of the deceased alternate payee is payable to the deceased alternate payee's surviving spouse, or if no surviving spouse, to the deceased alternate payee's estate.
(j) Subsections (a) and (b) of this section will apply to all domestic relations orders approved in accordance with this chapter after January 1, 2018, and to such domestic relations orders approved prior to that date as are construed to provide for such an annuity or withdrawal.
(k) If a qualified domestic relations order is received by the system after the participant begins receiving a retirement annuity, the system shall divide the annuity into two single life annuities; one payable to the alternate payee and the other payable to the participant in accordance with the order and the rules of the plan. The system shall compute the two single life annuities by determining the actuarial present value of participant's current annuity as of the date that the system has approved the order, and creating an annuity payable to the alternate payee based on the actuarial present value of participant's current annuity awarded under the order to the alternate payee and creating a second life annuity payable to participant based on the remaining actuarial present value of participant's current annuity. Payments to the participant and to the alternate payee cease upon their respective deaths.
(l) If a qualified domestic relations order is received by the system after the participant begins receiving a retirement annuity under which participant chose a dual life option, or a guaranteed term option and the term has not expired, and designated a person other than the alternate payee as beneficiary, then the system, in computing the two single life annuities to be paid to the participant and alternate payee respectively, shall first calculate the actuarial present value of the participant's current annuity that is not attributable to the beneficiary as of the date that the system has approved the order. The interest of the beneficiary in the participant's current retirement annuity will not be affected by the division of benefits. The actuarial present value of the participant's current annuity that is not attributed to the beneficiary is then divided into two single life annuities. The single life annuity payable to alternate payee is based on the actuarial present value of participant's current annuity not attributable to the beneficiary awarded under the order to the alternate payee, and the participant's single life annuity is computed based on the remaining actuarial present value of participant's current annuity not attributable to the beneficiary.
(m) The mortality assumption for alternate payees for determining the actuarial equivalent of a benefit payable to an alternate payee shall be the same as the mortality assumption for beneficiaries as set forth in §103.1 of this title (relating to Actuarial Tables) with regard to service retirements.
(n) If participant's employer grants a cost of living adjustment pursuant to the terms of the plan, and if the alternate payee has commenced an annuity, then the alternate payee is eligible to receive a cost of living adjustment to his or her annuity.
(o) Notwithstanding any other provision of this chapter, all distributions made under this chapter must be determined and made in accordance with §401(a) of the Internal Revenue Code, including but not limited to §401(a)(9); and §415.
