Summary
Mary Lou Thomas died in April 2016, leaving a three-flat Chicago property as part of her estate. After defendant Jessica Jackson, the successor executor named in the will, repeatedly violated probate court orders, the probate court found her disqualified and appointed the Cook County Public Administrator as independent administrator on December 20, 2022. Defendant did not appeal that order. The Administrator obtained authorization to pursue eviction proceedings against defendant and her daughter, who occupied one unit of the property. The eviction court entered an order of possession in favor of the Administrator on June 9, 2025, and denied defendant's motion to reconsider. Defendant appealed, arguing the probate appointment order was void and subject to collateral attack in the eviction proceedings, and that the eviction court abused its discretion in denying her motion to compel discovery.
The appellate court affirmed on both issues. On the void/voidable distinction, the court held that because the probate court had both subject matter and personal jurisdiction over the estate proceedings, any error in the appointment order rendered it merely voidable — not void. A voidable order must be challenged by timely direct appeal under Illinois Supreme Court Rule 303(a)(1), which defendant failed to pursue. Her attempt to collaterally attack the appointment order in the eviction proceedings was therefore improper. The court further noted that the eviction court, as a court of limited jurisdiction conducting summary proceedings focused solely on the right of possession, lacked authority to overturn a sister court's probate order. On discovery, the court held that the Administrator's expenditures and invoices were irrelevant to the sole question before the eviction court — superior right of possession — and denial of the motion to compel was not an abuse of discretion.
This decision is significant for probate and eviction practitioners because it reinforces that jurisdictional errors must be distinguished from mere legal errors, and that parties who fail to timely appeal probate court orders cannot relitigate those orders in collateral proceedings. Eviction courts will not entertain challenges to the propriety of an administrator's appointment, and discovery in eviction proceedings is strictly limited to matters germane to the right of possession.
Key Holdings
1. A probate court order appointing an independent administrator is voidable, not void, where the probate court had both subject matter and personal jurisdiction; it may only be challenged by timely direct appeal and is not subject to collateral attack in subsequent eviction proceedings.
2. Failure to appeal a probate court appointment order within 30 days under Illinois Supreme Court Rule 303(a)(1) forfeits the right to challenge that order in any future proceeding.
3. An eviction court, as a court of limited jurisdiction conducting summary proceedings, lacks authority to review or disregard a probate court's appointment order entered by a coordinate circuit court judge.
4. An eviction court does not abuse its discretion in denying a motion to compel discovery of an administrator's expenditures, receipts, and invoices where that information has no relevance to the sole issue before the eviction court — the superior right of possession of estate property.
