(40 ILCS 5/7-154) (from Ch. 108 1/2, par. 7-154)
    Sec. 7-154. Surviving spouse annuities - Eligibility.
    (a) A surviving spouse annuity shall be payable to the eligible surviving spouse of a participating employee, an employee annuitant, or a person who on the date of death would have been entitled to a retirement annuity, had he applied for such annuity, and who dies at any time when a surviving spouse annuity equals at least $5 per month, provided:
        (1) The surviving spouse (i) was married to the
    
participating employee for at least one year on the date of death, or (ii) was married to the annuitant or person entitled to a retirement annuity for at least one year prior to the date of termination of service, or (iii) was married to the deceased annuitant for at least one year on the date of the deceased annuitant's death, if at the time of termination of service the deceased annuitant was married for at least one year to a spouse who does not survive the deceased annuitant. (Item (iii) applies to the spouses of annuitants who die on or after the effective date of this amendatory Act of the 99th General Assembly, notwithstanding whether the annuitant was in service on or after that effective date or the effective date of Public Act 87-850.)
        (2) The male deceased employee annuitant or such
    
other person entitled to a retirement annuity had contributed to this fund for surviving spouse annuity purposes for at least 1 year or continuously since the effective date of the participating municipality or participating instrumentality.
        (3) The female deceased employee annuitant or such
    
other person entitled to a retirement annuity was in service on or after July 27, 1972, provided that the annuity shall not be computed on the basis of any retirement annuity effective before that date.
        (4) If the employee dies before termination of
    
service, the employee did not exclude the spouse from any death benefit or surviving spouse annuity pursuant to subsection (b) of Section 7-118. A designation of beneficiary naming a spouse and children jointly or a trust pursuant to subsection (b) of Section 7-118 shall preclude payment of a surviving spouse annuity.
    (b) If a person is the spouse of a retiring participating employee on the date of the initial payment of a retirement annuity and is qualified to receive a surviving spouse annuity upon the death of the employee and the surviving spouse contributions are not refunded to the employee, then a surviving spouse annuity shall be payable to that person even if the marriage to the employee is dissolved after that date.
    (c) Eligibility of a surviving spouse shall be determined as of the date of death. Only one surviving spouse annuity shall be paid on account of the death of any employee.
