(40 ILCS 5/15-120) (from Ch. 108 1/2, par. 15-120)
    Sec. 15-120. Beneficiary; survivor annuitant under portable benefit package. "Beneficiary": The person or persons designated by the participant or annuitant in the last written designation on file with the board; or if no person so designated survives, or if no designation is on file, the estate of the participant or annuitant. Acceptance by the participant of a refund of accumulated contributions shall result in cancellation of all beneficiary designations previously filed. A spouse whose marriage was dissolved shall be disqualified as beneficiary unless the spouse was designated as beneficiary after the effective date of the dissolution of marriage.
    After a joint and survivor annuity commences under the portable benefit package, the survivor annuitant of a joint and survivor annuity is not disqualified, and may not be removed, as the survivor annuitant by a dissolution of the survivor's marriage with the participant or annuitant.
