The deadline rule, discovery rule, minor tolling, and notice-of-claim requirements — in plain English, with a calculator at the bottom.
735 ILCS 5/13-212; 735 ILCS 5/2-622
2 years from discovery, with a **4-year hard repose** from the act. Combined — this is one of the shorter windows in the nation for late-discovered injuries. Minor tolling: under 18 = 8 years OR until age 22, whichever comes first. Illinois requires a **§2-622 affidavit of merit** from a qualified health professional before or shortly after filing. Wrongful-death cases: 2-year SOL runs from the date of death, not the date of the act.
