How Long Do You Have to File a Personal Injury Claim in Illinois?
Key takeaways
  • Most Illinois personal-injury claims have a two-year filing deadline.
  • Claims against a city, county, or state can carry a much shorter one-year deadline plus notice rules.
  • The deadline for a minor often does not start until they turn 18.
  • The “discovery rule” can delay the start date for injuries you couldn’t reasonably have known about.

One of the first questions injured people ask is simple: how long do I have to do something about this? In Illinois, the answer is governed by a rule called the statute of limitations — a strict legal deadline for filing a lawsuit. Miss it and even a strong case can be dismissed. If you’re unsure where your deadline falls, the safest move is to ask an attorney directly.

The general rule: two years

For most personal-injury claims in Illinois — car crashes, slip-and-falls, and similar negligence cases — you generally have two years from the date of the injury to file suit. If you do not file within that window, the court will almost always dismiss your case no matter how compelling the facts are. This is why the calendar, not just the evidence, can decide a case.

Important exceptions that change the clock

The two-year rule is the starting point, not the whole story. Several situations shorten or extend it:

Claims against the government

When your claim is against a government body — a city, transit authority, park district, or the State of Illinois — special rules apply. These claims often carry a shorter filing period of one year and, in some cases, strict notice requirements. Missing a government deadline is one of the most common ways a valid claim is lost.

Injuries to minors

When the injured person is a child, the clock is often paused until they turn 18, giving them time to bring a claim as an adult. The specifics depend on the type of case, so parents should still speak with a lawyer promptly rather than assume there is unlimited time.

The discovery rule

Some injuries are not obvious right away. The discovery rule can delay the start of the clock until the date you knew, or reasonably should have known, that you were injured and that it may have been caused by someone’s wrongdoing. This frequently matters in medical and exposure cases.

Wrongful death and medical malpractice

These claims follow their own separate timelines and repose periods. If you have lost a loved one or suspect a medical error, do not rely on the general two-year rule — get specific advice.

Why waiting is risky — even inside the deadline

Having two years does not mean you should use all of it. Surveillance footage is overwritten within weeks, vehicles are repaired, physical evidence is cleaned up, and witnesses forget details or move away. Insurance companies know this, and delay often works in their favor. The strongest cases are almost always the ones investigated early.

Talk to a lawyer before assuming your case is too old

Because the exceptions are so fact-specific, the only reliable way to know your real deadline is to have an attorney review the details. Not sure which category your situation fits?

Frequently asked questions

What is the statute of limitations for a car accident in Illinois?

Generally two years from the date of the crash for personal-injury claims. Shorter deadlines can apply if a government vehicle or entity is involved.

What happens if I miss the deadline?

If you file after the statute of limitations expires, the defendant can ask the court to dismiss your case, and it usually will — regardless of how strong your evidence is.

Does the deadline ever get extended?

Yes. Exceptions like the discovery rule, injuries to minors, and certain other circumstances can extend or pause the clock. These are fact-specific, so confirm with an attorney.

How soon should I contact a lawyer after an injury?

As soon as reasonably possible. Early investigation preserves evidence and protects your options — and an initial consultation is free.
