Illinois Statute of Limitations for Personal Injury Claims: What Chicago Residents Need to Know

If you’ve been injured in a car accident, a slip and fall, or a possible medical malpractice case in Chicago, you may have the right to pursue compensation, but only if you act within the law’s time window. That window is the statute of limitations, or the legal deadline to file a lawsuit. Once it passes, state courts may refuse to hear your case, no matter how strong your evidence or how serious your injuries.

The deadline depends on the type of claim you’re filing and the party you’re filing against. Some cases have two years, others have one, and certain exceptions can pause or restart the clock entirely. Knowing which timeline applies can affect whether you can pursue compensation at all.

Illinois Personal Injury Filing Deadlines Explained

There are specific time frames for filing a personal injury lawsuit in Illinois, and those deadlines vary depending on the circumstances of your injury.

The 2-Year General Rule

For most personal injury claims in Illinois, the filing deadline is two years from the date of injury. This rule is established under the state’s Code of Civil Procedure, which requires that personal injury lawsuits be filed within two years of the injury.

The Illinois statute of limitations for personal injury covers a wide range of case types, including:

  • Car crashes and truck accidents: Collisions caused by another driver’s negligence are generally subject to the two-year rule.
  • Slip and fall incidents: Property owner negligence that causes injury generally gives you two years to file, unless an exception applies.
  • Workers’ compensation third-party claims: The state’s Workers’ Compensation Act provides your remedy against your employer, but if a third party caused your workplace injury, you may also have grounds to file a separate personal injury lawsuit against that party. The two-year statute of limitations applies to the third-party claim.

Your filing deadline begins on the date of injury, not when you file your insurance claim, finish treatment or get the police report. That distinction matters because many injured people mistakenly assume they have more time than they actually do.

The Discovery Rule

Sometimes an injury isn’t immediately obvious. In these situations, the discovery rule adjusts the timing of your two-year deadline. Under this exception, the statute of limitations for personal injury in Illinois begins when the injured person knew, or reasonably should have known, both that an injury occurred and that another party’s conduct caused it. Both elements are required. For example, a construction worker who develops a repetitive-stress injury might not receive a diagnosis until months after the harmful activity began.

However, the discovery rule exists to address injuries that were genuinely undiscoverable, not situations where you delayed taking action on known injuries.

When the Standard Deadline Changes

Chicago residents are especially likely to encounter exceptions to the standard two-year rule. Treating any of the following situations like a standard personal injury claim can put your case at risk.

1. Government Entities

When the defendant, or the party being sued, is a local government entity, the Illinois Compiled Statutes (ILCS) set the statute of limitations at one year from the date the injury occurred or the legal claim arose. Chicago-specific examples where this shortened deadline applies include CTA bus accidents, CTA L train incidents on public transportation platforms or trains, injuries on park district property, and accidents involving city vehicles or employees.

Government-entity claims often involve shorter and more technical filing rules, so you should not assume the discovery rule will extend your deadline.

2. Medical Malpractice

Not every medical mistake qualifies as medical malpractice, but when a provider’s negligence causes harm, a separate statute may govern the filing deadline, with a two-part system:

  • Discovery deadline: In this context, “discovery” means the point at which the patient knew, or reasonably should have known, about the injury and its connection to medical care. Patients generally have two years from that point to file.
  • Statute of repose: This imposes a hard four-year cutoff from the date of the negligent act, regardless of when the patient discovers the harm. This outer limit can bar a claim before the patient even knows they were harmed. For example, if a surgeon leaves a foreign object inside your body during a 2026 procedure and you don’t discover it until 2031, the statute of repose has already expired.

In Illinois, the statute of limitations for medical malpractice extends to eight years for minors from the negligent act, or until their 22nd birthday, whichever comes first.

3. Wrongful Death Claims

When a personal injury results in death, the claim shifts from the general personal injury statute to the state’s Wrongful Death Act. Under this separate framework, the two-year deadline runs from the date of death, not the date of the underlying accident or negligence.

When Illinois Personal Injury Law Can Pause the Clock

Certain circumstances can pause, or toll, the statute of limitations. These exceptions provide additional protection for people who cannot reasonably file a lawsuit on their own behalf.

1. Injured Minors

If the injured person was under 18 at the time of injury, the statute of limitations clock does not start until they turn 18 under 735 ILCS 5/13-211. They then have two years to file, meaning the effective deadline is their 20th birthday for most general personal injury claims.

2. Legal Incapacity

Legal incapacity may toll the clock when the injured person is legally unable to manage their affairs at the time of injury. Once that incapacity is removed, the filing timeline may begin or resume. For example, someone who suffers a severe traumatic brain injury that leaves them unable to manage their own affairs would not have the statute of limitations running against them while they remain incapacitated.

What Stops the Clock and What Doesn’t

The statute of limitations is generally satisfied when you file a complaint in the appropriate court before the deadline expires. What matters is the court timestamp on your filed complaint, not when you prepared a draft or consulted your attorney.

If you reach a signed written settlement agreement before filing, the claim is resolved, and the deadline becomes irrelevant.
