Illinois Statute of Limitations for Personal Injury Claims

Under 735 ILCS 5/13-202, you have two years from the date of your injury to file a personal injury lawsuit in Illinois. This applies to car accidents, slip and falls, dog bites, and most other types of personal injury claims.

The two-year clock starts on the date the injury occurs — not the date you hire a lawyer, not the date you finish medical treatment, and not the date you realize how serious your injuries are (unless the discovery rule applies). Once the deadline passes, the defendant can ask the court to dismiss your case, and the court will grant that request.

Two years goes faster than most people expect. Building a strong personal injury case requires gathering evidence, obtaining medical records, consulting experts, and negotiating with insurance companies. Attorneys who handle Illinois injury claims recommend starting the process within weeks of the accident, not months or years later.

When a personal injury causes death, surviving family members can file a wrongful death lawsuit under the Illinois Wrongful Death Act (740 ILCS 180/2). The general deadline is 2 years from the date of death — not the date of the injury that ultimately caused the death.

There are two important exceptions. First, when death results from violent intentional conduct (such as homicide), the statute of limitations is extended to 5 years from the date of death. Second, when criminal charges of first degree murder, second degree murder, involuntary manslaughter, or reckless homicide are brought, the family has 1 year after the final disposition of the criminal case to file a wrongful death suit — even if the standard 2-year period has expired.

The wrongful death claim belongs to the personal representative of the deceased person's estate. If no estate has been opened, a family member must petition the court to appoint one before the lawsuit can be filed — another reason to start the process early.

If your injury was caused by an Illinois government entity — a city, county, park district, school district, or government employee acting in their official capacity — you face a significantly shorter deadline. Under the Local Governmental and Governmental Employees Tort Immunity Act (745 ILCS 10/8-101), you must file suit within 1 year of the date of injury.

In addition to the 1-year filing deadline, Section 8-102 of the Act requires you to serve proper notice on the government entity. The specific notice requirements and deadlines can vary depending on the type of government body involved. Failure to serve proper notice can result in permanent dismissal — the plaintiff is forever barred from suing, regardless of the merits of the claim.

This 1-year deadline is strictly enforced by Illinois courts. If your accident occurred on a government-maintained road, in a public building, involved a CTA bus or train, or involved any government vehicle or employee, consult an attorney immediately. The 1-year clock is already running.

Under 735 ILCS 5/13-211, the statute of limitations is tolled (paused) for individuals who are under a legal disability at the time of injury. In Illinois, this includes being a minor (under age 18) or being under other legal disabilities as defined by statute.

For minors, the 2-year statute of limitations does not begin to run until the child turns 18. This means a minor injured in an accident has until their 20th birthday to file a personal injury lawsuit. A parent or guardian can file on the child's behalf at any time before then, and there are practical reasons to do so — evidence deteriorates, witnesses become harder to locate, and memories fade.

For example, a child injured in a car accident at age 10 has until age 20 to file. A teenager injured at age 17 has until age 20 — just 3 years. The tolling provision provides important protection for minors, but parents should not assume there is no urgency. Starting the claims process early preserves evidence and strengthens the case.

Illinois recognizes the discovery rule, which can extend the statute of limitations in cases where the injury was not immediately known or discoverable. Under this rule, the 2-year clock does not start on the date of the incident but on the date the injured person knew — or, exercising reasonable diligence, should have known — about the injury and its possible wrongful cause.

Courts apply an objective "reasonable person" standard. The question is not when you personally realized you were injured, but when a reasonable person in your situation would have discovered the injury and its connection to someone else's negligence. The burden of proving that delayed discovery was reasonable falls on the injured party.

The discovery rule most commonly applies in medical malpractice cases, where a surgical error or misdiagnosis may not become apparent for months or years. It can also apply in toxic exposure cases, defective product cases, and other situations where harm develops gradually. The discovery rule does not give you unlimited time — you must still file within 2 years of the date you knew or should have known about the injury.

Medical malpractice claims in Illinois have their own statute of limitations under 735 ILCS 5/13-212. The general rule is 2 years from the date the plaintiff knew or should have known of the injury and its wrongful cause — the discovery rule is built into the statute.

However, there is a hard cap: a 4-year statute of repose from the date of the negligent act or omission. This means that regardless of when you discover the malpractice, you cannot file suit more than 4 years after it occurred. The only exception is fraudulent concealment — if a medical provider intentionally hid their wrongdoing, you have 5 years from the date you discover the concealment (735 ILCS 5/13-215).

For minors, the rules are more generous. A child has up to 8 years from the date of the negligent act to file a medical malpractice claim, but no later than their 22nd birthday. This extended period reflects the fact that children cannot advocate for themselves and may not discover medical errors until years later.

If you file a personal injury lawsuit after the statute of limitations has expired, the defendant will raise it as a defense. Illinois courts treat the statute of limitations as a strict bar — there is no grace period, no good-cause exception for most cases, and no judicial discretion to extend it simply because the claim has merit.

Missing the deadline means you lose the ability to file a lawsuit. Without the leverage of a potential lawsuit, insurance companies have no incentive to negotiate a fair settlement. In practice, missing the statute of limitations means losing your claim entirely.

This is why personal injury attorneys in Illinois strongly recommend consulting a lawyer as soon as possible after an injury. Even if you are unsure whether you have a case, a brief consultation can clarify your deadlines and protect your right to file.
