(40 ILCS 5/14-120) (from Ch. 108 1/2, par. 14-120)
    Sec. 14-120. Survivors annuities - Conditions for payments. A survivors annuity is established for all members of the System. Upon the death of any male person who was a member on July 19, 1961, however, his widow may have the option of receiving the widow's annuity provided in this Article, in lieu of the survivors annuity.
    (a) A survivors annuity beneficiary, as herein defined, is eligible for a survivors annuity if the deceased member had completed at least 1 1/2 years of contributing creditable service if death occurred:
        (1) while in service;
        (2) while on an approved or authorized leave of
    
absence from service, not exceeding one year continuously; or
        (3) while in receipt of a non-occupational disability
    
or an occupational disability benefit.
    (b) If death of the member occurs after withdrawal, the survivors annuity beneficiary is eligible for such annuity only if the member had fulfilled at the date of withdrawal the prescribed service conditions for establishing a right in a retirement annuity.
    (c) Payment of the survivors annuity shall begin immediately if the beneficiary is 50 years or over, or upon attainment of age 50 if the beneficiary is under that age at the date of the member's death. In the case of survivors of a member whose death occurred between November 1, 1970 and July 15, 1971, the payment of the survivors annuity shall begin upon October 1, 1977, if the beneficiary is then 50 years of age or older, or upon the attainment of age 50 if the beneficiary is under that age on October 1, 1977.
    If an eligible child or children, under the care of the spouse also survive the member, the survivors annuity shall begin immediately without regard to whether the beneficiary has attained age 50.
    Benefits under this Section shall accrue and be payable for whole calendar months, beginning on the first day of the month after the initiating event occurs and ending on the last day of the month in which the terminating event occurs.
    (d) A survivor annuity beneficiary means:
        (1) A spouse of a member or annuitant if:
            (i) in the case of a member or annuitant who dies
        
before the effective date of this amendatory Act of the 91st General Assembly, the current marriage with the member or annuitant was in effect for at least one year at the date of death or withdrawal, whichever first occurs; or
            (ii) in the case of a member or annuitant who
        
dies on or after the effective date of this amendatory Act of the 91st General Assembly, the current marriage with the member or annuitant was in effect for at least one year immediately prior to the date of death, regardless of the date of withdrawal.
        (2) An unmarried child under age 18 (under age 22 if
    
a full-time student) of the member or annuitant; an unmarried stepchild under age 18 (under age 22 if a full-time student) who has been such for at least one year at the date of the member's death or at least one year at the date of withdrawal, whichever first occurs; an unmarried adopted child under age 18 (under age 22 if a full-time student); and an unmarried child over age 18 if he or she is dependent by reason of a physical or mental disability, so long as the physical or mental disability continues. For purposes of this subsection, disability means inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months.
        (3) A dependent parent of the member or annuitant; a
    
dependent step-parent by a marriage contracted before the member or annuitant attained age 18; or a dependent adopting parent by whom the member or annuitant was adopted before he or she attained age 18.
    (e) Payment of a survivors annuity to a beneficiary terminates upon: (1) remarriage before age 55 that occurs before the effective date of this amendatory Act of the 91st General Assembly or death, if the beneficiary is a spouse; (2) marriage or death, if the beneficiary is a child; or (3) remarriage before age 55 or death, if the beneficiary is a parent. Remarriage of a prospective beneficiary prior to the attainment of age 50 disqualifies the beneficiary for the annuity expectancy hereunder, if the remarriage occurs before the effective date of this amendatory Act of the 91st General Assembly. Termination due to marriage or remarriage shall be permanent, regardless of any future changes in marital status.
    The substantive changes made to this subsection by this amendatory Act of the 91st General Assembly (pertaining to remarriage prior to age 55 or 50) apply without regard to whether the deceased participant or annuitant was in service on or after the effective date of this amendatory Act.
    Any person whose survivors annuity was terminated during 1978 or 1979 due to remarriage at age 55 or over shall be eligible to apply, not later than July 1, 1990, for a resumption of that annuity, to begin on July 1, 1990.
    (f) The term "dependent" relating to a survivors annuity means a beneficiary of a survivors annuity who was receiving from the member at the date of the member's death at least 1/2 of the support for maintenance including board, lodging, medical care and like living costs.
    (g) If there is no eligible spouse surviving the member, or if a survivors annuity beneficiary includes a spouse who dies or is disqualified by remarriage, the annuity is payable to an unmarried child or children. If at the date of death of the member there is no spouse or unmarried child, payments shall be made to a dependent parent or parents. If no eligible survivors annuity beneficiary survives the member, the non-occupational death benefit is payable in the manner provided in this Article.
    (h) Survivor benefits do not affect any reversionary annuity.
    (i) If a survivors annuity beneficiary becomes entitled to a widow's annuity or one or more survivors annuities or both such annuities, the beneficiary shall elect to receive only one of such annuities.
    (j) Contributing creditable service under the State Universities Retirement System and the Teachers' Retirement System of the State of Illinois shall be considered in determining whether the member has met the contributing service requirements of this Section.
    (k) In lieu of the Survivor's Annuity described in this Section, the spouse of the member has the option to select the Nonoccupational Death Benefit described in this Article, provided the spouse is the sole survivor and the sole nominated beneficiary of the member.
    (l) The changes made to this Section and Sections 14-118, 14-119, and 14-128 by this amendatory Act of 1997, relating to benefits for certain unmarried children who are full-time students under age 22, apply without regard to whether the deceased member was in service on or after the effective date of this amendatory Act of 1997. These changes do not authorize the repayment of a refund or a re-election of benefits, and any benefit or increase in benefits resulting from these changes is not payable retroactively for any period before the effective date of this amendatory Act of 1997.
