Illinois Personal Injury Law Resources

Illinois is widely considered one of the more plaintiff-friendly personal injury states in the country. The state imposes no caps on compensatory damages including in medical malpractice cases, after the Illinois Supreme Court struck down legislative damage caps as unconstitutional. Combined with modified comparative negligence that allows recovery up to 50% fault, mandatory uninsured motorist coverage, a diminished value right, and Cook County's active trial docket, Illinois provides strong protections for injured parties. The state does limit damages in claims against state government to $2 million.

Statute of Limitations

Illinois's general personal injury statute of limitations is two years from the date of injury under 735 ILCS 5/13-202. This applies to most negligence-based claims including motor vehicle accidents, slip-and-fall injuries, premises liability, and general negligence.

Specific Deadlines

Wrongful death: Two years from the date of death (not the date of injury). If a person is injured in January 2024 and dies from those injuries in November 2025, the wrongful death deadline runs from November 2025.

Medical malpractice: Two years from when the plaintiff discovered or should have discovered the injury, subject to a hard four-year statute of repose from the date of the negligent act (735 ILCS 5/13-212). For minors, the statute extends to eight years from the date of injury but no later than the minor's 22nd birthday.

Property damage: Five years from the date of damage under 735 ILCS 5/13-205.

Defamation: One year under 735 ILCS 5/13-201.

Product liability: Subject to a 12-year statute of repose from the product's first sale (735 ILCS 5/13-213(b)).

Minors: The statute of limitations is tolled until the child turns 18, giving them until age 20 to file in most personal injury cases. Parents can and often should file on behalf of the minor before then.

Discovery Rule

Illinois applies the modified discovery rule the statute begins when the plaintiff knew or should have known that the injury was wrongfully caused, even if they did not know it was legally actionable. This is particularly important in medical malpractice and toxic exposure cases.

Government Claims Strict Short Deadlines

State government: Claims against the State of Illinois are heard exclusively by the Illinois Court of Claims. The injured party must file a lawsuit or submit a Notice of Intent of Claim within one year of the injury. If notice is filed, the plaintiff has up to two years to file suit (705 ILCS 505/22).

Local governments: Claims against cities, counties, and local government employees must generally be filed within one year of the injury in regular circuit court. Some municipalities (notably Chicago) require a written notice of claim within six months under the Local Governmental and Governmental Employees Tort Immunity Act.

These short government deadlines catch many plaintiffs off guard and can permanently bar otherwise valid claims.

Modified Comparative Negligence (51% Bar)

Illinois follows a modified comparative negligence rule. A plaintiff can recover damages as long as their percentage of fault is not more than 50%. If the plaintiff is more than 50% at fault, they are completely barred from recovery.

When the plaintiff's fault is 50% or less, damages are reduced proportionally. A plaintiff found 25% at fault with $100,000 in damages would recover $75,000.

Illinois's 51% bar threshold is more favorable to plaintiffs than the stricter 50% bar used in states like Georgia and Idaho, because a plaintiff who is exactly 50% at fault can still recover in Illinois.

Damage Caps NONE in Private Cases

No Caps on Compensatory Damages

Illinois does not cap economic or non-economic damages in personal injury cases. There is no statutory limit on medical expenses, lost wages, pain and suffering, emotional distress, loss of normal life, or any other category of compensatory damages.

In 2005, the Illinois legislature attempted to impose caps on non-economic damages in medical malpractice cases ($500,000 against physicians, $1 million against hospitals). The Illinois Supreme Court struck down these caps in Lebron v. Gottlieb Memorial Hospital (2010), holding that they violated the separation of powers clause of the Illinois Constitution. The court reasoned that the legislature cannot dictate to the judiciary the amount of damages a plaintiff may recover.

This makes Illinois one of the most favorable states for large verdicts, particularly in medical malpractice, trucking, and catastrophic injury cases.

Punitive Damages

Illinois allows punitive damages in appropriate cases to punish egregious conduct. There is no statutory cap on punitive damages in private cases, though they must bear a reasonable relationship to the compensatory damages awarded.

Government Claims $2 Million Cap

Total damages against the State of Illinois are typically limited to $2 million per claim (705 ILCS 505/8), except in cases involving state-owned vehicles driven by state employees, where different limits may apply.

Auto Insurance Requirements

Illinois is an at-fault (tort) state. The driver who caused the accident bears financial responsibility for the other party's injuries and damages.

Illinois's minimum auto liability insurance requirements are 25/50/20:

• $25,000 per person for bodily injury
• $50,000 per accident for bodily injury
• $20,000 per accident for property damage

Mandatory Uninsured Motorist Coverage

Illinois is one of the states that requires uninsured motorist bodily injury (UMBI) coverage. This coverage cannot be waived and must be carried at a minimum of 25/50 (matching the liability minimums). This provides important protection given that approximately 12–15% of Illinois drivers are estimated to be uninsured.

Underinsured motorist (UIM) coverage is not mandatory but is strongly recommended and is automatically included if the policyholder purchases UM limits above the state minimum.

Diminished Value State

Illinois is a diminished value state, allowing drivers to recover the loss in their vehicle's resale value after an accident even after complete repairs from the at-fault party's insurer.

No PIP Requirement

Illinois does not require Personal Injury Protection (PIP) or no-fault coverage. Optional medical payments coverage is available.

Where Personal Injury Cases Are Filed

Personal injury lawsuits in Illinois are filed in Circuit Court, which is the state's trial court of general jurisdiction. Illinois has 24 judicial circuits. Venue is generally proper in the county where the defendant resides or where the injury occurred.

Cook County Circuit Court (Chicago) handles the highest volume of personal injury litigation in the state and is among the busiest trial courts in the nation. Cook County has historically been known for large jury verdicts.

The Small Claims Division handles cases up to $10,000. Cases in the $10,001–$50,000 range are heard in the Law Division Municipal District.

Important note on venue: Illinois has seen legislative attention regarding venue reform, particularly regarding efforts to prevent forum shopping in Cook County and Madison/St. Clair Counties (the Metro East region near St. Louis), which have historically been considered plaintiff-friendly jurisdictions.

Common Types of Personal Injury Cases in Illinois

Illinois's large population (third most populous state), extensive highway system (including the I-90/I-94, I-55, I-57, and I-80 corridors), heavy commercial trucking traffic, and major metropolitan area (Chicago) generate enormous volumes of personal injury litigation. Common case types include motor vehicle accidents, semi-truck and commercial vehicle accidents (Illinois is a major freight hub), motorcycle injuries, pedestrian and bicycle accidents, CTA and Metra public transportation injuries, rideshare accidents, premises liability, medical malpractice, product liability, construction accidents (including Chicago high-rise construction), nursing home abuse and neglect, wrongful death, dog bites, workplace injuries, toxic exposure and occupational disease claims, and Biometric Information Privacy Act (BIPA) violations. Illinois's agricultural sector also generates farm equipment and agricultural accident claims downstate.
