How Long Do You Have to File a Personal Injury Claim in Illinois?

In Illinois, you generally have two years from the date of your injury to file a personal injury lawsuit. The rule comes from 735 ILCS 5/13-202, and it covers most car accidents, truck accidents, slip and falls, dog bites, and other negligence claims. Some cases have shorter deadlines, including a one-year limit for claims against a city, county, or other local government body, and a few situations pause or extend the clock. Once the deadline passes, the court will almost always dismiss the case no matter how strong it is.

Deadlines are easy to ignore while you are focused on getting better. People assume there is time to heal first and deal with the legal side later. That assumption has cost many injured people in Illinois any chance of compensation. This guide covers the general rule, the deadlines for specific types of cases, the exceptions that change the clock, and what to do now. It is part of our wider personal injury practice.

What a Statute of Limitations Is

A statute of limitations is a legal deadline for filing a lawsuit. After it passes, a court will rarely hear the case, even with strong evidence and serious injuries. Think of it like a store's return window. The claim can be completely valid, but if you show up after the window has closed, the store can say no. Illinois sets these deadlines by statute, and different types of cases have different windows.

Illinois also uses a second kind of deadline called a statute of repose. A statute of repose is an absolute cutoff that applies even if the statute of limitations would otherwise be paused. The medical malpractice four-year cap is the most common example, and it is explained below.

Illinois Deadlines by Type of Case

Standard Personal Injury: Two Years

Car accidents, truck accidents, motorcycle and bicycle crashes, slip and falls, dog bites, and most other negligence claims must be filed within two years of the injury under 735 ILCS 5/13-202. The clock usually starts on the day of the accident.

Wrongful Death: Two Years From the Date of Death

When an injury is fatal, the family's claim runs under the Illinois Wrongful Death Act. Under 740 ILCS 180/2, the lawsuit must be filed within two years of the death, not the date of the original accident. The deadline extends to five years when the death resulted from violent intentional conduct. Only the personal representative of the estate can file, which takes time to arrange, so these cases should not be left until the second year.

Medical Malpractice: Two Years From Discovery, Four-Year Cap

Medical malpractice claims follow 735 ILCS 5/13-212. You have two years from the date you knew, or reasonably should have known, about the injury. But Illinois adds a strict statute of repose: no claim can be filed more than four years after the act or omission that caused the harm, even if you did not discover it until later. For minors, the limit is eight years from the act, but never past the child's 22nd birthday.

Product Liability: Two Years, With a Repose Cap

Claims against the maker or seller of a defective product carry the standard two-year limit, measured from when you knew or should have known of the injury. Under 735 ILCS 5/13-213, there is also a repose period: no claim can be filed more than 12 years after the product was first sold by the seller, or 10 years after delivery to the first owner, whichever comes first.

Claims Against Government Bodies: One Year

If your injury involves a city bus, a pothole on a public road, a park district, a public school, or an employee of a local government, the Local Governmental and Governmental Employees Tort Immunity Act (745 ILCS 10/8-101) cuts the deadline to one year. This is the deadline Illinois residents most often miss, because they assume the two-year rule applies to everyone. Claims against the State of Illinois itself go to the Court of Claims and have their own notice requirements, so get advice quickly.

Dram Shop Claims: One Year

If you were hurt by a drunk driver and want to bring a claim against the bar or restaurant that overserved them, the Illinois Dram Shop Act (235 ILCS 5/6-21) gives you one year, not two.

Workers' Compensation: Separate Rules

A work injury runs on a different track. Under the Illinois Workers' Compensation Act, you must notify your employer within 45 days of the accident, and a claim must be filed within three years of the injury or two years after the last benefit payment, whichever is later. If someone other than your employer caused the injury, the separate lawsuit against that third party still carries the two-year personal injury deadline.

Hit-and-Run and Uninsured Driver Claims

If the at-fault driver fled or has no insurance, your claim often runs through your own uninsured motorist coverage. Your insurance policy sets its own notice deadlines, which can be much shorter than two years, and a hit-and-run usually has to be reported to police promptly for the claim to be valid.

Exceptions That Change the Clock

The Discovery Rule

The countdown does not always start on the day of the accident. When an injury is not reasonably discoverable right away, Illinois courts start the clock on the date you discovered, or should have discovered, that you were hurt and that someone else may be responsible. This matters most in medical malpractice and exposure cases, such as a surgical error that causes no symptoms for months, or a toxic exposure that leads to illness years later. The discovery rule never overrides a statute of repose.

Injuries to Minors

Under 735 ILCS 5/13-211, the statute of limitations is paused, or "tolled," until a child turns 18. The injured person then has two years from their 18th birthday to file, even if the accident happened years earlier. A parent can file on the child's behalf sooner, and usually should.

Legal Disability

The same section pauses the clock for a person who is under a legal disability at the time of the injury, meaning they cannot manage their own affairs. The two years begin when the disability is removed.

The Defendant Leaves Illinois

If the person responsible leaves the state before you can file, the time they are absent generally does not count against the deadline.

Statutes of Repose Cap Everything

Tolling and the discovery rule can extend a deadline, but a statute of repose puts a hard stop on the claim regardless. The four-year medical malpractice cap is the clearest example. An adult who learns of a surgical error five years after the surgery has no claim, even though they could not have known sooner. This can feel unfair, and it is one reason to see a doctor and a lawyer as soon as something seems wrong.

Why Waiting Hurts Even When You Have Time

Two years sounds like a long time. In practice, the useful part of that window is much shorter. Evidence disappears fast: skid marks fade, security footage is overwritten within days or weeks, and injuries heal in ways that make it harder to prove how they happened. Witnesses move or forget. Insurance adjusters know this, and some will slow-walk negotiations hoping you run out of time without filing. Once the deadline passes, they have no reason to offer anything.

Waiting also makes it harder to hire a lawyer. An attorney who takes a case in its final weeks has to file suit immediately, before reviewing medical records or police reports, and may decline the case rather than do that. Filing late also adds court costs that a timely settlement could have avoided.

What to Do Now

1. See a doctor right away, even if you feel fine. Some injuries take days to show symptoms, and the medical record ties the injury to the accident.
2. Report the incident to the right party: police for a crash, your employer for a work injury, the property manager for a fall.
3. Save everything. Photos of the scene and injuries, medical bills, the police report, and the names of witnesses. Our guide on evidence that strengthens a claim lists what matters most.
4. Do not give a recorded statement to an insurance company or sign any release before you talk to a lawyer.
5. Find out which deadline applies to your case. If a government body, a bar, or a hospital is involved, assume the window is shorter than two years until a lawyer confirms otherwise.

Frequently Asked Questions

What is the statute of limitations for personal injury in Illinois?

Two years from the date of the injury for most cases, under 735 ILCS 5/13-202. Shorter deadlines apply to claims against local government bodies (one year) and dram shop claims (one year).

Does the two-year clock start on the accident date or the discovery date?

Usually the accident date. If the injury was not reasonably discoverable right away, as in some medical malpractice and exposure cases, the clock starts when you discovered or should have discovered it. A statute of repose can still cut the claim off.

How long do I have to sue a city or county in Illinois?

One year from the date of injury under the Tort Immunity Act, 745 ILCS 10/8-101. This applies to municipalities, counties, park districts, school districts, and their employees.

What is the statute of limitations for wrongful death in Illinois?

Two years from the date of death under 740 ILCS 180/2, or five years if the death resulted from violent intentional conduct.

What happens if I miss the deadline?

The defense will ask the court to dismiss the case, and the court almost always will. The strength of your evidence does not matter at that point.

Should I still call a lawyer if I think the deadline has passed?

Yes. Tolling for minors or legal disability, the discovery rule, or a defendant's absence from Illinois may extend your window. Only a lawyer who reviews the facts can tell you whether a path remains.
