Medical negligence settlements
in Illinois.

By Reviewed by Abd Shanti, Founder9 min read

An Illinois malpractice complaint must come with a health professional’s written report saying the case has merit. Once past that step, there is no cap on damages, and appeals courts have upheld both modest and very large verdicts.

Facts that decide a medical negligence claim in Illinois

Certificate and reportThe complaint must attach an affidavit that a health professional found reasonable and meritorious cause for the action, plus that professional’s written report.735 ILCS 5/2-622(a)(1), as quoted in Owens v. Riverside Medical Center (Ill. App. 2020)
Damages capsNone. The noneconomic caps for medical cases were held unconstitutional.Lebron v. Gottlieb Memorial Hospital (Ill. 2010)
Jury unanimityJurors must agree unanimously that the doctor was negligent, but need not agree on which specific act was negligent.Galich v. Advocate Health (Ill. App. 2024)
Deadline to sueTwo years: injury actions “shall be commenced within 2 years next after the cause of action accrued.”735 ILCS 5/13-202, as quoted in Mickiewicz v. Generations at Regency (Ill. App. 2020)
Fault ruleYou are barred only if your contributory fault is more than 50% of the proximate cause of the injury; otherwise the award is reduced by your share.735 ILCS 5/2-1116, as explained in Gratzle v. Sears, Roebuck (Ill. App. 1993)

★ IL · medical negligence · in practice

What changes the number here.

What actually moves a medical negligence settlement in Illinois.

  1. 1

    Get the report before filing. Section 2-622 requires a written report from a health professional with the complaint, and defendants move to dismiss when it is missing or thin.

  2. 2

    Surgical errors with clear consequences are provable. In Vanderhoof the cut bile duct, the repair surgery and the chain of complications that followed gave the jury a clear story.

  3. 3

    Jury instructions matter in a case alleging several errors. Galich holds jurors need only agree the doctor was negligent, not on which of the alleged failures it was.
