AI Rules for Illinois Law Firms
Last verified July 8, 2026
Illinois already has one AI statute in force affecting any firm with Illinois employees, a Supreme Court policy governing AI use in state court work, and more than 50 pending AI bills in the General Assembly, one of which would directly change how family law evidence is authenticated. This page separates what is already binding from what is still moving through Springfield.
Where Illinois Stands
The Illinois Supreme Court has adopted a Policy on Artificial Intelligence governing AI use in state court work. Separately, Public Act 103-0804 (HB 3773) amended the Illinois Human Rights Act to address AI in employment decisions, and is already in effect. A further bill, SB 3901 in the 104th General Assembly, would add a new evidentiary rule for AI-generated evidence in marriage dissolution proceedings but has not been enacted; as of its February 2026 bill page it was one of more than 50 pending Illinois AI bills.
What Your Firm Must Do
Under the Illinois Supreme Court's AI policy, attorneys may use AI in state court work without a blanket disclosure duty to the court, but remain fully responsible under the Rules of Professional Conduct and existing sanctions rules for verifying anything AI contributed to a filing, including catching hallucinated citations before they are filed. If your firm has Illinois employees and uses AI in recruiting, hiring, promotion, or discipline, Public Act 103-0804 requires you to notify workers and ensure those tools have no discriminatory effect, including effects that operate through proxies such as zip code; the Illinois Department of Human Rights had proposed notice rules that were later withdrawn, but the underlying statutory duties remain in force.
What's Still Pending
SB 3901 would let either party in a family law case require the court to review suspected AI-generated or manipulated evidence under Supreme Court Rule 901. It has not passed, but litigation teams should start building AI-evidence authentication practices now given the direction Illinois is heading with its broader slate of pending AI legislation.
