Comparative Fault in Illinois Slip and Fall Injury Cases

A slip and fall in Chicago can happen in seconds, but the legal aftermath can last months or even years. One of the most misunderstood parts of that process is comparative fault, which is the legal rule that decides what happens when both you and a property owner share some responsibility for the accident. Many injured people walk away from valid claims because they assume being even slightly at fault means they cannot recover anything. Under Illinois law, that assumption is wrong. If you were hurt on someone else’s property, knowing how comparative fault works could be the difference between receiving full compensation and receiving nothing at all. A Chicago personal injury lawyer at Briskman Briskman & Greenberg can help you understand exactly where you stand.

What Is Comparative Fault Under Illinois Law?

Illinois has adopted modified comparative negligence under 735 ILCS 5/2-1116 as the standard for recovery of damages. This law applies directly to slip and fall cases, and it changes the way fault is calculated when more than one party contributed to an accident. Before Illinois adopted this system, the old contributory negligence rule was brutal. If you were even 1% at fault, you recovered nothing. The modified system is far more fair to injured people.

Under modified comparative negligence, an injured party may recover damages only if they are less than 50% at fault for the injury, but the recovered amount may be reduced in proportion to the degree that the injured party was at fault. So if a jury decides you were 30% responsible for your fall on a wet floor at a Wicker Park grocery store, your total damages are reduced by 30%. You still recover 70% of what you are owed. That is a meaningful recovery, not a total loss.

For example, if the property owner is determined to be 80% at fault and you are determined to be 20% at fault, you can collect for your damages because you were less than 50% at fault. However, the other party’s insurance company might only offer to pay 80% of your damages. That gap between what you deserve and what an insurer offers is exactly why having legal representation matters.

The 50% threshold is a hard line. If the negligence attributable to the injured party was more than 50% of the total fault, he or she will be barred from receiving any recovery. But reaching that threshold requires evidence, and insurance companies work hard to push your percentage as high as possible. Do not let them do it without a fight.

How Comparative Fault Plays Out in Chicago Slip and Fall Cases

Picture this: you are walking through Millennium Park on a rainy afternoon, and you slip on a wet tile surface near the Cloud Gate. You were wearing flip-flops. The property manager had no wet floor signs posted anywhere. Who is at fault? The answer is probably both parties to some degree, and that is where comparative fault analysis begins.

The Illinois Premises Liability Act (740 ILCS 130/) governs personal injury claims related to unsafe property conditions, and property owners and occupiers must maintain their premises in a reasonably safe condition and warn visitors of any known hazards. When a property owner skips those basic duties, they carry fault. When a visitor ignores obvious risks or acts carelessly, they may carry some fault too.

In a real slip and fall case, the trier of fact (a jury or judge) weighs all the evidence. They look at what the property owner knew, how long the hazard existed, whether warnings were posted, and whether the injured person acted reasonably. Factors that often push fault onto the injured person include distracted walking, ignoring warning signs, wearing inappropriate footwear, or entering a clearly restricted area. Factors that push fault onto the property owner include failing to clean up spills, ignoring reports of a hazard, poor lighting, broken flooring, or missing handrails on stairs.

Chicago courts see these cases regularly. Whether the fall happens at a River North restaurant, a Gold Coast hotel, or a South Side parking garage, the same legal standard applies. In Illinois, comparative negligence can play a significant role in premises liability cases. Under Illinois’ modified comparative negligence rule, a plaintiff may still recover damages even if they are partially at fault for the accident, as long as they are not more than 50% responsible for the injury. The goal is to make sure every party pays their fair share, not to let negligent property owners off the hook simply because the injured person was not perfect.

How Joint and Several Liability Works When Multiple Parties Are at Fault

Slip and fall cases in Chicago sometimes involve more than one defendant. Think about a fall in a Logan Square apartment building where the landlord owns the property, a management company handles maintenance, and a janitorial contractor was supposed to clean the floors. All three may share some portion of fault. Illinois law has specific rules about how that shared liability works.

Under 735 ILCS 5/2-1117, all defendants found liable are jointly and severally liable for a plaintiff’s past and future medical and medically related expenses. That means any one of those defendants can be held responsible for the full amount of your medical bills, regardless of their individual percentage of fault. For other damages like lost wages and pain and suffering, the rules are slightly different. Any defendant whose fault is less than 25% of the total fault is only severally liable for those non-medical damages. Any defendant whose fault is 25% or greater is jointly and severally liable for those damages as well.

Why does this matter to you? It matters because if one defendant cannot pay their share, you are not automatically stuck absorbing that loss. The joint and several liability rule for medical expenses protects injured people from being left without compensation just because one party is judgment-proof or bankrupt. A skilled slip and fall attorney knows how to identify every liable party and pursue each one appropriately under these rules.

This is especially important in cases involving construction sites near the Chicago Riverwalk, warehouse facilities on the city’s West Side, or large commercial properties in the Loop where multiple contractors and subcontractors may all have contributed to a dangerous condition.

What Insurance Companies Do With Comparative Fault

Insurance adjusters are trained to use comparative fault as a tool to reduce or eliminate what they pay you. The moment you file a claim after a slip and fall, the adjuster assigned to your case starts building a file designed to increase your percentage of fault. They may point to your footwear, your familiarity with the property, the time of day, or even social media posts that suggest you were distracted. Every detail they find becomes ammunition.

One of the most common tactics is to get you on a recorded phone call shortly after your accident. The adjuster sounds friendly and concerned, but their goal is to get you to say something that places more blame on you. Saying “I was in a hurry” or “I should have been more careful” can be used to inflate your fault percentage and shrink your settlement offer.

The insurance company will make the injured party an offer based on what it believes to be the amount of negligence of its insured. The insurance company may interview the involved parties, including witnesses, and it may also review the accident report in order to determine the amount of the offer. That offer almost always benefits the insurer, not you.

A slip and fall lawyer at Briskman Briskman & Greenberg can handle all communication with the insurance company on your behalf. That alone prevents many of the mistakes that reduce settlements. Evidence like surveillance footage, incident reports, witness statements, and maintenance records all become critical tools for pushing back against an inflated fault percentage. The stronger your evidence, the harder it is for an insurer to shift blame onto you.

Why Your Fault Percentage Matters So Much to Your Recovery

The math behind comparative fault is simple, but the stakes are enormous. If your damages total $200,000 and you are found 10% at fault, you recover $180,000. If you are found 40% at fault, you recover $120,000. If you are found 51% at fault, you recover zero. That is a $200,000 swing based entirely on how fault is assigned. This is why fighting for the lowest possible fault percentage is one of the most important things your legal team can do.

The existence of a duty of care is held in Illinois state statute 740 ILCS 130/1. This law, the Premises Liability Act, establishes that property owners owe a duty of reasonable care under the circumstances to invitees and licensees. When a property owner breaches that duty, and that breach causes your injury, they carry fault. Your attorney’s job is to document that breach thoroughly and present it in the most compelling way possible.

Proving the property owner’s negligence requires solid evidence. Photographs of the hazard, maintenance logs showing the owner knew about the problem, testimony from people who reported the issue before your fall, and expert witnesses who can speak to industry safety standards all work together to build a strong case. Whether you fell on a cracked sidewalk in Bridgeport, a greasy kitchen floor in Chinatown, or a broken staircase near a CTA station, the same evidence-gathering process applies.

Illinois also requires that you file your personal injury lawsuit within two years of the date of your injury under 735 ILCS 5/13-202. Missing that deadline ends your case entirely. An slip and fall attorney at Briskman Briskman & Greenberg can make sure your claim moves forward within the required time frame and that no critical evidence disappears while you wait.

If you were hurt in a slip and fall anywhere in Chicago, do not assume your partial fault eliminates your right to compensation.

FAQs About Comparative Fault in Illinois Slip and Fall Cases

Can I still recover compensation if I was partly at fault for my slip and fall in Chicago?

Yes. Under 735 ILCS 5/2-1116, Illinois follows a modified comparative negligence rule. You can recover damages as long as your share of fault is 50% or less. Your total compensation is reduced by your fault percentage, but you are not barred from recovery unless your fault exceeds 50%.

What happens if I am found exactly 50% at fault for my slip and fall?

At exactly 50% fault, you can still recover under Illinois law. Your damages are reduced by half, but you retain the right to compensation. The bar to recovery only applies when your fault exceeds 50%, not when it equals it.

How does an insurance company determine my percentage of fault after a slip and fall?

Insurance adjusters review accident reports, interview witnesses, examine surveillance footage, and look at the circumstances of your fall, including where it happened, what you were wearing, and whether warning signs were present. They assign a fault percentage that typically favors their insured. This is why having an attorney review any offer before you accept it is so important.

What if multiple property owners or contractors are responsible for my slip and fall injury?

Illinois law under 735 ILCS 5/2-1117 addresses this directly. All defendants found liable are jointly and severally liable for your past and future medical expenses. For other damages, defendants with 25% or more of the total fault are also jointly and severally liable. This means you are not stuck absorbing losses caused by a defendant who cannot pay.

How long do I have to file a slip and fall lawsuit in Illinois?

Under 735 ILCS 5/13-202, you generally have two years from the date of your injury to file a personal injury lawsuit in Illinois. If you are filing a claim against a government entity, like the City of Chicago, shorter notice deadlines may apply. Missing these deadlines eliminates your right to pursue compensation in court, so contacting an attorney as soon as possible after your injury is critical.
