As the new year begins, Illinois courts are operating under a revised set of Supreme Court rules that took effect on January 1, 2026. While these amendments apply broadly to civil practice, their impact on probate and estate matters is particularly significant. Kravets Law Group, a Chicago-based firm specializing in business, real estate, and estate law, is proactively preparing its clients and referral partners for these changes.
The amendments include updates to Rules 13, 22, 605, 606, and 706, among others. These changes reinforce the court's emphasis on proper filing procedures, efficient case management, and adherence to deadlines. For families involved in probate administration, trust disputes, or estate litigation, these procedural details can often determine the outcome of a case.
“Court rules don't get the attention that statutes do, but in contested estate matters they often decide the outcome,” said founding attorney Daniel Kravets. “Details that impact how a motion is filed, when a response is due, or how a judge manages the case can determine whether a family gets in and out of court efficiently or ends up stuck in litigation for years.”
Probate and trust matters are not the primary focus of these amendments, but they operate under the same civil court rules and are therefore affected whenever those rules change. For families navigating the probate process, the practical implications are straightforward. Petitions to open or close an estate, executor and trustee accountings, motions in contested matters, and notices to interested parties all must comply with the current rules of practice. A filing rejected for a technical defect can delay an estate administration by weeks or months, and a missed deadline in a contested matter can forfeit an argument entirely.
In Illinois probate litigation cases involving will contests, trustee removal actions, claims against an estate, or breach of fiduciary duty allegations, the stakes are even higher. Procedural positioning often matters as much as the underlying facts. Rules governing motion practice, case management conferences, and discovery deadlines directly affect how contested matters move through the courts.
“Most families hope never to see the inside of a probate courtroom, and the goal of a good estate plan is to keep it that way,” Kravets added. “But when disputes do arise, procedural expertise isn't optional. Clients deserve an attorney who knows the rules cold and uses them to move the case forward rather than getting tripped up by them.”
The firm also encourages Illinois families to treat these rule changes as a reminder to review their estate plans more broadly. Clear, well-drafted wills and trusts, carefully chosen executors and trustees, and up-to-date beneficiary designations are the best defenses against litigation—regardless of how the procedural rules evolve.
