How Long Do Personal Injury Cases Take?

Key Takeaways

• Most Illinois personal injury claims resolve somewhere between a few months and three years.
• Medical treatment usually sets the pace because a claim cannot be valued accurately until your condition stabilizes.
• Filing a lawsuit does not mean a trial, and most filed cases still end in a negotiated resolution.
• Illinois filing deadlines cap the outer clock, and several of them run shorter than the standard two years.

Most personal injury cases take between four months and three years to resolve, depending on the injury and the insurer. That range feels unhelpful when medical bills arrive every month, and your paycheck has shrunk or stopped altogether.

A modest soft tissue claim with clear fault can settle after a single round of negotiation. A herniated disc with surgery, a disputed police report, and two insurance carriers is a different situation, and it can run past the two-year mark.

At Conboy Law, we map a realistic schedule at the start of a case and revise it as treatment and evidence develop. Our team can review the specifics of your claim and tell you what a reasonable timeline looks like for your circumstances.

How Long Personal Injury Cases Take in Illinois

The honest answer depends on where your case stops. Claims fall into three broad tracks, and each one has its own rhythm.

Claims That Resolve Without a Lawsuit

Most injury claims never become lawsuits. When fault is documented and treatment wraps up quickly, we can often assemble records, send a demand, and negotiate a resolution within four to ten months of the incident.

Insurers move faster when liability is clear, and damages are easy to verify. They slow down when the medical picture is still changing.

The waiting in this track is rarely dramatic. Requesting complete records from a hospital system can take four to six weeks, and a single missing radiology report can hold up an entire demand package. Adjusters also rotate files, and a new adjuster often wants time to review everything again.

Claims That Require Filing Suit

When a carrier refuses to negotiate reasonably, filing suit resets the schedule. A filed case in Cook County commonly takes one to three years, since written discovery, depositions, and expert disclosure each consume months.

Filing is often a pressure step rather than a commitment to trial. Many cases resolve after depositions, once both sides have seen how the testimony holds up.

Claims That Reach a Jury

Trial-track cases sit at the long end of the range. Court calendars in the county are crowded, and a firm trial date frequently lands two to three years after the complaint is filed.

Very few injury cases finish that way. The ones that do usually involve catastrophic injuries, contested fault, or a carrier that has drawn a hard line on value.

Case profiles help set expectations, and a few patterns show up again and again:

• Clear fault, minor injury, treatment complete: four to ten months.
• Disputed fault, moderate injury: nine to eighteen months.
• Serious injury with ongoing treatment: eighteen months to three years.
• Multiple defendants or an insurance coverage dispute: two years or longer.
• Medical malpractice or any claim requiring expert review: two to four years.

These are patterns rather than predictions, and the facts of your case control the actual schedule.

The Stages of an Illinois Injury Claim, Start to Finish

Nearly every case moves through the same sequence, even when the pace varies widely. The stages below show where the months actually go:

1. Medical treatment continues until your condition stabilizes.
2. Our team investigates liability and collects records, wage documentation, and bills.
3. A demand package goes to the insurer with the full value of your losses.
4. Negotiation runs for several weeks, sometimes considerably longer.
5. A complaint is filed if the carrier will not offer fair value.
6. Written discovery and depositions take place.
7. Mediation or arbitration gives both sides a settlement checkpoint.
8. Trial happens only if the case is not resolved.

Cases can stall at any of these points, and the earliest stages are where most of the time is spent.

Why Medical Treatment Sets the Pace

A claim cannot be valued accurately until you reach maximum medical improvement (MMI), the point where your doctors expect no further significant recovery. Resolving a claim before that moment means guessing at future surgery, therapy, and permanent limitations.

Soft tissue injuries often reach MMI within two to four months. Fractures, disc injuries, and surgical cases can take eight to eighteen months, which extends the claim by roughly the same amount.

What Happens in the First Six Months After Filing

Filing starts a court-supervised schedule. Illinois Supreme Court Rule 218 requires a case management conference within 35 days after the parties are at issue, and no more than 182 days after the complaint is filed.

At that conference, the judge sets discovery deadlines and either a trial date or a date for the next conference. The resulting order controls the pace of the case from then on.

Written discovery usually comes first, with each side answering interrogatories and producing documents. Depositions follow, and scheduling several witnesses around court reporters, treating physicians, and opposing counsel routinely adds weeks. Expert disclosure sits at the end of that sequence, which is why the second year of a filed case often moves faster than the first.

Illinois Deadlines That Cap Your Timeline

Deadlines do not tell you how long a case takes, but they do control how long you can wait to start one. Missing one ends the claim regardless of its strength.

Two Years for Most Injury Claims

Illinois requires most actions for damages for an injury to the person to be commenced within two years after the cause of action accrued, under 735 ILCS 5/13-202. For a crash or a fall, that clock generally starts on the date of the incident.

One Year Against a Local Public Entity

Claims involving a city, a transit agency, a park district, or a school district run on a much shorter clock. A civil action against a local public entity or its employees generally must be commenced within one year, under 745 ILCS 10/8-101. Actions arising out of patient care are the exception, and those get two years from discovery with a four-year outer limit.

Medical Malpractice Deadlines

Malpractice actions against a physician, dentist, registered nurse, or hospital must be brought within two years of the date the injured person knew or should have known of the injury. In no event may such an action be brought more than four years after the act or omission, under 735 ILCS 5/13-212. Where the injured person was under 18 when the claim accrued, that outer limit extends to eight years, but never past the person's 22nd birthday.

Minors and Legal Disability

Someone who was under 18 or under a legal disability when a claim accrued may bring the action within two years after turning 18 or after the disability is removed, under 735 ILCS 5/13-211. A child hurt at age ten therefore has until age twenty to file, though evidence rarely survives that long in usable condition.

Cook County Rules That Speed a Case Up or Slow It Down

Mandatory Arbitration for Smaller Claims

Cook County assigns qualifying civil matters to an arbitration calendar. Municipal District injury actions seeking money damages that do not exceed $30,000 are assigned to arbitration under Part 18 of the local rules. Other civil cases may be transferred when no claim carries a value above that threshold.

Arbitration hearings occur months earlier than a trial date would. Either side can reject the award and request a trial, which restarts part of the wait.

A hearing itself is short, usually a fraction of a day before a panel of attorneys rather than a jury. For a smaller claim, that shortcut can pull resolution forward by a year or more. The tradeoff is that an award neither side accepts sends the case back into the ordinary trial queue.

Prejudgment Interest and the Insurer's Offer Window

Illinois law gives insurers a financial reason to move sooner. Prejudgment interest of six percent per year accrues on injury and wrongful death judgments from the date the action is filed, capped at five years, under Public Act 102-0006.

A defendant can reduce or eliminate that interest by making a written settlement offer within twelve months of filing. Governmental entities are exempt from prejudgment interest, which is one reason claims against public bodies often move slowly.

What Makes One Case Take Longer Than Another

Disputed Fault Under the 51% Rule

Illinois bars recovery when an injured person's contributory fault is more than 50% of the proximate cause, and reduces damages proportionally at 50% or less, under 735 ILCS 5/2-1116. Because the gap between 40% and 51% can decide whether a claim has value at all, carriers fight hard over fault percentages, and that fight consumes months.

Consider a pedestrian struck mid-block. If the driver's carrier argues the crossing was improper, the case may need scene photographs, video, and a reconstruction opinion before anyone discusses numbers seriously.

Multiple Defendants, Policy Limits, and Liens

Cases with several defendants take longer because each carrier evaluates the claim separately and each may point toward the others. Coverage disputes add another layer when policy limits are unclear or a business carrier denies responsibility.

Medical liens also affect the final weeks. Health insurers and treating providers holding liens must be identified and negotiated before funds are distributed to you.

Lien work is quiet but slow. A hospital lien, a health plan with reimbursement rights, and an outstanding balance with a surgeon each require separate correspondence. Handling those in parallel with settlement negotiation, rather than after it, is one of the few reliable ways to shorten the last stretch of a case.
