Two Rules Working Together
Every personal injury claim in Illinois moves within two structural rules that shape how much time a person has to act and how much their own conduct might affect what they recover. Understanding both from the outset helps set realistic expectations rather than learning the details partway through a case, since insurers routinely raise both issues once a claim is underway.
The Two-Year Filing Deadline
Under 735 ILCS 5/13-202, most personal injury claims in Illinois must be filed within two years of the date of injury. This covers car accidents, slip and falls, and most other negligence-based claims. Claims against a local government entity generally carry a shorter one-year window, and wrongful death claims run two years from the date of death rather than the date of the underlying injury.
- Standard personal injury claims: two years from the injury date
- Claims against local government entities: generally one year
- Medical malpractice: two years from discovery, with a four-year outer limit
- Wrongful death: two years from the date of death
How Illinois Handles Shared Fault
Illinois follows a modified comparative fault rule under 735 ILCS 5/2-1116. A claimant can recover damages as long as their own fault does not exceed fifty percent of what caused the injury. Once that threshold is crossed, recovery is barred entirely. Below it, damages are reduced in proportion to the claimant’s own share of fault.
Why These Two Rules Interact
A claim with disputed fault often takes longer to resolve than a straightforward one, since both sides may need to gather evidence supporting their version of what happened. That investigation takes time, and starting it well before the filing deadline leaves more room to build a strong position on the fault question rather than rushing an incomplete case to the courthouse.
What a Fault Dispute Looks Like in Practice
Insurance adjusters in Chicago routinely propose a fault percentage that favors the insurer, since every percentage point assigned to a claimant directly reduces the payout owed. A claimant found thirty percent at fault in a case worth one hundred thousand dollars in damages recovers seventy thousand dollars rather than the full amount, and a shift of even ten percentage points changes that number substantially.
This dynamic means the fault conversation often carries as much financial weight as the underlying damages calculation itself. A claimant who accepts an inflated fault percentage without pushing back, simply to move the process along faster, can end up losing far more than the time saved by a quicker resolution would have been worth.
Building Evidence That Supports a Lower Fault Percentage
Photos from the scene, witness statements, traffic camera footage, and a timely police report all help establish an accurate picture of what happened before memories fade or physical evidence disappears. A Chicago personal injury lawyer evaluating a claim typically prioritizes this kind of evidence early, since the fault percentage question often gets contested well before any conversation about the total damages figure begins.
Why Evidence Preservation Cannot Wait
Surveillance footage from nearby businesses is frequently overwritten within days or weeks. Skid marks fade from the roadway. Witnesses move or simply forget specific details as time passes. None of these realities are affected by the two-year filing deadline, which is why evidence preservation and legal deadlines need to be treated as two separate clocks rather than one, each requiring its own kind of urgency from the very first days after an incident.
Approaching a Claim With Both Rules in Mind
A Chicago personal injury lawyer at Disparti Law Group works through both the timing and fault questions from the first conversation with a client, since a claim that looks straightforward at first can shift considerably once an insurer starts arguing about shared responsibility.
