From Intake to Jury: How an Illinois Injury Case Is Built for Trial

Cases prepared for trial from the first week are the ones that settle for what they are worth. Every stage, in order.

By Lincoln Square Law · 7-minute read

Most injury cases settle. The ones that settle well are usually the ones that were prepared as if they would be tried. A case built for a jury from the first week has preserved evidence, complete medical proof, identified witnesses, and damages supported by documents, and an insurer evaluating that file has to account for the real possibility of a verdict. This guide walks through how an Illinois injury case moves from the first conversation to trial, what happens at each stage, and what the client can expect to do.

Stage one: intake and the first decisions

The first meeting sets the foundation. The lawyer’s early questions are practical ones. Who was involved, and who owned the vehicles or property? Were any public entities involved? What insurance applies? What treatment has the client received, and what records exist?

Two decisions are made immediately. The first is the deadline. Most Illinois personal injury claims must be filed within two years (735 ILCS 5/13-202), but claims against local public entities and their employees generally must be filed within one year (745 ILCS 10/8-101). The second is preservation. Preservation letters go to the defendants, their insurers, and anyone holding video, vehicle data, or records that could be lost.

Stage two: investigation

The investigation gathers what the other side will not volunteer. It usually includes the crash or incident report, scene photographs and measurements, witness interviews, surveillance and dashcam video, vehicle inspection and event data, and, in more complex cases, an accident reconstruction. Property records, maintenance logs, and contracts identify who controlled a premises or a job site. The goal is to identify every responsible party and to understand the fault picture before anyone else frames it, because Illinois bars recovery by a plaintiff found more than 50% at fault (735 ILCS 5/2-1116).

Stage three: treatment and damages

While the investigation proceeds, the client’s job is to get well and to follow medical advice. The medical records created during this stage become the evidence of the injury. Gaps in treatment and unreported symptoms become defense arguments. The lawyer gathers records and bills, tracks lost income, and, for serious injuries, begins to develop the proof of future care and lost earning capacity that may require experts such as life-care planners and economists.

Stage four: the claim and the demand

Some cases resolve before suit. When the client has reached a stable point in treatment and the damages can be documented, the lawyer may present a demand package to the insurer: liability evidence, medical records, bills, wage loss documentation, and a statement of the damages. Liens and reimbursement claims are identified at this stage so that any offer can be evaluated in terms of what the client will actually receive.

Stage five: filing suit

If the claim does not resolve, or a deadline approaches, the lawyer files a complaint. In Cook County, injury cases seeking larger damages are generally filed in the Law Division of the Circuit Court, while smaller claims are heard elsewhere and may be assigned to mandatory arbitration under the Supreme Court Rules and local rules. Filing suit changes the defendant’s calculations. Defense costs, discovery obligations, and exposure to a jury all begin to accrue, and in Illinois personal injury cases, prejudgment interest generally begins to accrue on damages from the date the action is filed, subject to statutory adjustments (735 ILCS 5/2-1303(c)).

Stage six: written discovery and depositions

Discovery is where each side obtains the other side’s evidence. It includes written interrogatories and disclosure of witnesses and expert opinions (Ill. S. Ct. R. 213), requests for documents and electronically stored information (Ill. S. Ct. R. 214), and, where a party’s physical or mental condition is at issue, an examination by a physician chosen by the defense (Ill. S. Ct. R. 215). Depositions follow, including the plaintiff’s, the defendant’s, witnesses’, and treating physicians’. The court manages the schedule through case management conferences (Ill. S. Ct. R. 218).

For the client, discovery means answering written questions under oath, producing records, attending an examination, and giving a deposition. Preparation for each step matters, because the answers will be used for the rest of the case.

Stage seven: experts

Serious injury cases are usually decided in part by experts: physicians who explain the injury and its cause, life-care planners who project future care, economists who calculate present value and lost earnings, and, where liability is disputed, engineers or reconstructionists. Illinois requires disclosure of each controlled expert’s opinions and the bases for them (Ill. S. Ct. R. 213(f)(3)), and expert testimony must satisfy the state’s foundation requirements (Ill. R. Evid. 702 and 703).

Stage eight: mediation and settlement

Many cases resolve at mediation, a confidential negotiation with a neutral mediator, often after key depositions and expert disclosures. By then, both sides know the strengths and weaknesses of the evidence. The client decides whether to accept any offer. Before deciding, the client should see a settlement statement showing the gross amount, fees, costs, liens as resolved, and the net amount.

Stage nine: trial

Trial preparation includes motions to exclude or admit evidence, preparation of witnesses, exhibits and demonstratives, jury instructions, and, when a party’s appearance or documents are needed, notices to produce them at trial (Ill. S. Ct. R. 237). The trial itself includes jury selection, opening statements, the plaintiff’s case, the defense case, closing arguments, jury instructions, and deliberations.

How a verdict is allocated among defendants matters. A defendant whose fault is less than 25% of the total fault attributable to the plaintiff, the defendants sued by the plaintiff, and certain third-party defendants is generally only severally liable for damages other than medical expenses, while defendants at or above that threshold are jointly and severally liable (735 ILCS 5/2-1117). That rule affects which defendants are pursued and how a case is tried.

After the verdict

Post-trial motions generally must be filed within 30 days after judgment (735 ILCS 5/2-1202), and a notice of appeal generally within 30 days after the judgment or the ruling on the last timely post-trial motion (Ill. S. Ct. R. 303). A verdict may be reduced, affirmed, or reversed, and many cases settle during this period as well.

How long it takes

A case that resolves before suit may take months, mostly because the demand should wait until the injury and its future course are understood. A case that is filed usually takes longer, often measured in years rather than months, depending on the court’s calendar, the number of parties, the need for experts, and how long treatment continues. Some delay works for the client, because settling before the medical picture is clear can leave future care uncompensated. Other delay does not, which is why a lawyer should be able to explain, at each stage, what is being done and what is being waited for.

The client’s role, stage by stage

• Early: tell your lawyer everything, get treatment, keep records, and avoid discussing the case with insurers or on social media.
• During the case: attend appointments, respond to discovery requests promptly, and prepare carefully for your deposition and any examination.
• At resolution: review the settlement statement or the trial strategy with your lawyer, ask questions, and make the decision that is yours to make.

A file built for trial settles for what it is worth

A case built for trial from the beginning is the case most likely to settle for what it is worth. Each stage, from the first preservation letter to the last expert disclosure, either strengthens the file or leaves a gap the defense will use. Knowing the sequence helps a client understand why the work is done in the order it is, and what each step contributes to the result.
