760 ILCS 85/1
Whenever any surety on the bond of any trustee of any fund or property appointed by any last will or other instrument in writing or appointed or created in any other manner than by appointment by a court, or any heir, executor or administrator of such surety, desires to be released from further liability upon any such bond, he, she or it may file an action for that purpose, in the circuit court, against such trustee and all other persons interested in such fund or property, including any other surety or sureties upon such bond, setting forth the facts relating to such bond and praying for the release of such surety. The practice in such action shall be the same as near as may be, as in other civil cases, and the court shall have power to compel such trustee, within such reasonable time as may be fixed by the court for that purpose, to make and execute a new bond in the same or greater penalty and with like conditions, as near as may be, as the original bond and with good and sufficient sureties to be approved by the court, or, in default of the execution of such new bond, may remove such trustee and compel the trustee to account and bring into court such trust fund or property or to deliver or transfer the same to such new trustee as may be appointed by the court to receive the same, and the court may enter all such other orders in the case, including an order releasing such surety, or heir, executor or administrator, as may appear to be just and right for the protection of all persons interested in such fund or property.
