Why Illinois Is Different

Under 735 ILCS 5/2-1116, a claimant whose contributory fault is more than 50% is barred from recovering damages in the negligence action. At 50% or less, any damages allowed are reduced by that percentage. A 50/50 finding therefore permits half of the proven damages; it does not guarantee an insurance payment.

When Professional Help Tends to Make Sense

Most minor accidents in Illinois are resolved between the drivers and their insurance companies without ever involving an attorney. Many accident victims, however, consider consulting an attorney when one or more of the following applies:

  • A fatality occurred, or a wrongful-death claim may be involved
  • Medical bills are already in the tens of thousands of dollars, or still growing
  • There is a permanent injury, visible scar, or any sign of traumatic brain injury (TBI)
  • The insurance company's first settlement offer feels far below your actual costs
  • The insurance company is arguing that your injuries are pre-existing, or trying to shift primary fault onto you
  • Multiple vehicles or multiple parties are involved and liability is unclear
  • Fault is disputed — especially relevant given Illinois's modified comparative fault rule
  • The Illinois statute of limitations for personal injury (2 years from the accident) is within six months
  • A government vehicle, commercial truck, or rideshare driver is involved
  • The other driver was uninsured, underinsured, or fled the scene (hit-and-run)

Find independent legal-help and consumer-agency resources. Contact a provider directly and confirm its scope and fees. TurnYourClaim does not arrange a consultation or transmit your claim.

If Fault Is Disputed

  • At 50% or less contributory fault, allowed damages are reduced proportionally; above 50%, recovery is barred. Ask for the evidence supporting any disputed allocation.
