The short answer

A wrongful death claim survives shared fault. Illinois uses modified comparative negligence, so the recovery is reduced in proportion to the share of fault assigned to the person who died, and it is barred entirely only where that share is more than 50%.

The statute covers these cases directly. 735 ILCS 5/2-1116 applies to “all actions on account of bodily injury or death,” bars recovery where contributory fault “is more than 50% of the proximate cause,” and expressly preserves recovery where it is “not more than 50%.”

Whose conduct is being judged

This is the question families ask first, and the answer is reassuring. The fault weighed against the claim is that of the person who died, not the conduct of the spouse, the children or the personal representative bringing the case.

That follows from what the claim is. A wrongful death action asks whether the death was caused by someone else’s wrongful act, and the defense answers that the deceased contributed to it. Nothing a beneficiary did or failed to do enters that calculation.

It also means the evidence fight is about a person who cannot give their account. That asymmetry is the defining feature of these cases, and it is why the physical and documentary record matters more here than in an injury case where the claimant can testify.

What the arithmetic looks like

Take a claim a jury values at $1,000,000 in total damages, then apply the share assigned to the person who died.

Illustrative figures only. Source: 735 ILCS 5/2-1116.

Illinois is sometimes called a “51% bar” state, which is accurate, and just as often a “50% rule” state, which is not. A single percentage point separates half a claim from no claim, and it is decided by a jury rather than by the adjuster who first put a number on the file.

Fault is divided among everyone, not just the parties

A second allocation runs alongside the first. Where more than one person or company contributed, the fault is apportioned among all of them, and 735 ILCS 5/2-1117 then decides who actually has to pay what.

• Medical expenses are treated separately. All defendants found liable are jointly and severally liable for the past and future medical and medically related expenses, so any one of them can be pursued for that whole category.
• For everything else, 25% is the line. A defendant whose fault is 25% or more of the total is jointly and severally liable for the remaining damages. A defendant below 25% is severally liable only, meaning responsible for its own share alone.

The practical consequence is easy to miss. If a defendant assessed at 24% is uninsured or out of business, that share may simply be uncollectable, whereas at 26% the remaining defendants can be pursued for it. The apportionment argument is therefore not only about the deceased’s share.

The arguments defendants actually make

In fatal cases the recurring themes are narrow and predictable:

• Speed, impairment or distraction on the part of the person who died.
• Seat belt or helmet use, raised routinely and worth taking to a lawyer rather than conceding.
• Right of way, particularly where a pedestrian crossed outside a crosswalk or a driver turned across traffic.
• Assumption of a known risk, common where the death occurred at work or on a job site.
• An empty chair. Blaming an absent party who was never sued, which is precisely why identifying every potential defendant before filing matters.

What answers these is not argument but reconstruction: vehicle data, scene evidence, camera footage, and the physical record. All of it decays quickly, which is covered in our post on how to file an Illinois wrongful death claim.

The empty chair argument deserves particular attention, because it is the one a family can do least about after the fact. A defendant is entitled to point at someone who is not in the case, and if that party was never sued and the limitation period against them has run, the share attributed to them may simply reduce what is collectable. Identifying every potential defendant before filing is the only reliable answer, and it is why the investigation phase is not a formality.

The seat belt argument, and why Illinois blocks it

Of all the fault arguments raised after a fatal crash, this is the one families assume is fatal to the claim. In Illinois it is not, and the statute says so directly.

625 ILCS 5/12-603.1(c) provides that failure to wear a seat safety belt in violation of that Section “shall not be considered evidence of negligence, shall not limit the liability of an insurer, and shall not diminish any recovery for damages arising out of the ownership, maintenance, or operation of a motor vehicle.”

Three separate protections sit in that sentence. It is not evidence of negligence, so it should not be weighed in the comparative fault allocation at all. It does not cap what an insurer owes. And it does not reduce the recovery.

That does not make every belt-related argument disappear, and how the provision applies in a given case is a question for a lawyer rather than an assumption. But a family told flatly that “he wasn’t wearing a belt, so there is nothing here” is being told something the Vehicle Code contradicts, and it is worth raising before accepting any reduction on that basis.

What a reduced recovery still covers

Reduction applies to the whole award, not to particular categories, so everything the claim compensates is scaled by the same proportion. That includes lost financial support, the value of services the person provided, lost society and companionship, and the grief, sorrow and mental suffering the Act names expressly.

A survival claim under 755 ILCS 5/27-6, covering what the person suffered between the injury and death, is reduced on the same basis. We set out the categories in our post on what damages a wrongful death claim recovers.

One thing shared fault does not change: who receives the money. The court still distributes the recovery among the surviving spouse and next of kin in proportion to each person’s dependency on the deceased, as we explain in who can file a wrongful death lawsuit.

What actually shifts the percentage

Because the person who could describe the moment is not there, these allocations are settled by physical evidence rather than by testimony. The material that moves a number:

• Vehicle data. Event data recorders capture speed, braking and belt status in the seconds before impact, and heavy vehicles add telematics on top.
• The scene itself. Sight lines, signal timing, road surface and lighting, all of which change or are repaired within weeks.
• Video. Business, doorbell and dashcam footage, which typically overwrites in one to two weeks.
• The vehicles, unrepaired. Crush patterns and impact angles frequently contradict a surviving driver’s account.
• Reconstruction. An expert who can convert all of the above into an opinion about who did what, and when.

A police report is a starting point rather than a conclusion. Officers reach a view quickly with limited information, and a citation, or its absence, does not bind anyone in the civil case.

Why an early percentage is not a finding

Insurers assign a share of fault early, on incomplete information, and it is a negotiating position rather than a determination. Only the trier of fact allocates fault, and only if the case is tried. Most resolve before that, which means the operative number is the one both sides believe a jury would reach.

What moves it is evidence. In a case where the person who died cannot explain what happened, that evidence is physical and documentary, and it is at its most complete in the first weeks.
