A number is shown only when at least two surveys agree; otherwise we leave it out. Laws change, so confirm with the statute cited or your state court before you rely on a figure.

  • Lawyers: Allowed; required for corporations suing or counterclaiming.
  • Appeals: 30 days.

Deadlines to file a lawsuit in Illinois

The deadline to file a personal injury lawsuit in Illinois is generally 2 years, which is the same as the most common period of 2 years across the country (Ill. Comp. Stat. 735, Art. 5, § 13-202). For a written contract the period is 10 years and for an oral contract 5 years.

Worth knowing: Minors’ cases tolled up to age 18 or 8 years max for med-mal.

Deadlines can start later or pause in some situations, and claims against government bodies often have much shorter notice periods. See what a statute of limitations is and what to do after a car accident.

Security deposits in Illinois

We could not confirm a single statutory deadline for returning security deposits in Illinois from our sources, so we do not state one here. Check the state landlord-tenant statute or your state attorney general's tenant guide, and read our general guide to security deposits.
