Section 40 ILCS 5/1-120 - Payment to trust(a) If a person is a minor or has been determined by a court to be under a legal disability, any benefits payable to that person under this Code may be paid to the trustee of a trust created for the sole benefit of that person while the person is living, if the trustee of the trust has advised the board of trustees of the pension fund or retirement system in writing that the benefits will be held or used for the sole benefit of that person. The pension fund or retirement system shall not be required to determine the validity of the trust or of any of the terms of the trust. The representation of the trustee that the trust meets the requirements of this Section shall be conclusive as to the pension fund or retirement system. Payment of benefits to the trust shall be an absolute discharge of the pension fund or retirement system's liability with respect to the amounts so paid.(b) For purposes of this Section, "minor" means an unmarried person under the age of 18.(c) This Section is not a limitation on any other power to pay benefits to or on behalf of a minor or person under legal disability that is granted under this Code or other applicable law.
