Third-Party Construction Accident Claims in Illinois

What makes a third party legally responsible on an Illinois jobsite

Workers’ compensation is the exclusive remedy against the company that employs you. Under 820 ILCS 305/5(a) that bar protects your direct employer and nobody else. Every other company on a construction site — the general contractor, other subcontractors, the property owner, equipment manufacturers, suppliers, delivery operators — is a third party, and an ordinary negligence claim against them is not blocked by the fact that you are collecting comp benefits. Both can run at the same time.

Illinois repealed the Structural Work Act in 1995, so there is no construction-specific strict liability statute to fall back on. The main route against a general contractor today is the retained-control doctrine, drawn from Section 414 of the Restatement (Second) of Torts. The question is whether the general contractor kept meaningful control over the manner and method of the work that caused the injury — not merely whether it had authority to stop unsafe work in the abstract. Contracts, daily logs, safety meeting minutes and the identity of whoever was giving instructions on the day all bear on that.

A word of caution that belongs on this page: a general contractor will often argue it was a borrowing employer and therefore entitled to the same exclusive remedy immunity as your direct employer. Whether that argument succeeds turns on the specific facts of supervision, payment and the right to control the work. It is the first defence raised in many of these cases and it should be evaluated early rather than discovered late.

What a third-party claim can recover that comp cannot

• Pain and suffering, and loss of a normal life.
• The full value of lost earnings, rather than the statutory two-thirds.
• Future lost earning capacity where the injury ends a trade career.
• Disfigurement and emotional distress.
• A spouse’s claim for loss of consortium in appropriate cases.

Two rules that shape the outcome

Comparative fault. Under 735 ILCS 5/2-1116 an injured worker’s recovery is reduced by their own share of fault, and is barred entirely if they are found more than 50 percent at fault. Defence teams in construction cases invest heavily in shifting blame onto the worker, which is another reason early evidence preservation matters.

The comp lien. Where a third-party case produces a recovery, the workers’ compensation carrier is generally reimbursed for benefits it paid, under 820 ILCS 305/5(b). Where the worker is represented, that lien is reduced by 25 percent for attorney fees plus a share of costs. Related to this is the Kotecki cap, which limits how much an employer brought into the lawsuit can be made to contribute — unless it signed a waiver, which construction subcontracts very often contain.

A third-party lawsuit generally must be filed within two years of the injury under 735 ILCS 5/13-202, a shorter and separate clock from the workers’ compensation deadline. Where a government entity may be a defendant, shorter notice requirements can apply.
