What Does a Personal Injury Lawyer Do? The Process from Intake to Resolution

A personal injury lawyer in Illinois turns an injury into a paid claim. The work is concrete: preserve the evidence that disappears in the first 72 hours, build the medical record so causation is provable, deal with every adjuster and lienholder so you don’t have to, file inside the two-year deadline at 735 ILCS 5/13-202, and either negotiate a settlement that actually pays your bills or take the case to a Peoria County jury. You pay nothing unless the lawyer recovers.

The short answer, before the long one

People ask “what does a personal injury lawyer do” because they’re trying to figure out whether the work justifies the fee. It does, and here is exactly what the work is. We’re going to walk through it the way it actually unfolds at Parker & Parker’s office on Perry Avenue in Peoria—from the first phone call to the day the check clears.

1. The first phone call: triage, conflict check, and statute math

The first call lasts about twenty minutes. Three things have to happen before anything else.

Triage. Is there a claim worth pursuing? In Illinois, that almost always means three boxes have to check: (1) somebody else’s negligence caused the injury, (2) the injury produced real, documentable harm—medical treatment, lost income, ongoing limitation—and (3) there is insurance or assets at the other end. If any of those is missing, an honest lawyer says so on the first call instead of stringing the case along.

Conflict check. The firm runs the names of every party—driver, owner, employer, insurer—against its open and closed matters to make sure there’s no ethical bar to representation.

Statute math. The clock started running on the date you got hurt. 735 ILCS 5/13-202 gives you two years from the date of injury for most personal-injury claims in Illinois. Wrongful death is two years from the date of death. Medical malpractice is two years from when you knew or should have known of the injury, with a four-year outside cap (735 ILCS 5/13-212). Claims against a city, county, or other Illinois governmental body shrink to one year (745 ILCS 10/8-101). Calendaring those dates is the first thing that happens in a new file, and it gets calendared in three places.

2. Evidence preservation in the first 72 hours

This is the work that distinguishes a careful firm from a settlement mill. The cases that pay the most are the ones where evidence got locked down before it disappeared. A lawyer sends the following on a typical car-crash file in the first three days:

A formal preservation letter to the defendant driver, the defendant’s employer if it’s a commercial vehicle, and any commercial property owner—putting them on notice not to destroy dashcam footage, telematics, ELD logs, employment records, training records, and maintenance histories. Spoliation in Illinois carries real consequences (see Boyd v. Travelers, 166 Ill. 2d 188 (1995)) and the letter creates the record.
Open-records requests to the responding agency for the crash report, body-cam footage, dispatch audio, and any reconstruction notes. In Peoria County the lawyer knows which agency to ask and how long they take.
A scene visit, often with a photographer or videographer, before the skid marks weather away or the broken sign gets replaced.
Witness identification and signed statements while memory is still photographic—typically the first weekend.

None of that happens on its own. That’s the work.

3. Building the medical record so causation is provable

Insurance carriers don’t pay because someone was hurt. They pay because someone proves the hurt is both real and caused by their insured. That proof lives in the medical record, and the medical record has to be assembled, organized, and explained.

The lawyer’s role here is concrete:

Send HIPAA-compliant records and bills requests to every treating provider—emergency department, primary care, orthopedic, physical therapy, imaging center, pharmacy.
Track the records through follow-up. Major hospital systems in central Illinois—OSF Saint Francis, Carle Health Methodist Hospital (formerly UnityPoint Methodist), Carle BroMenn—each have their own records process and their own typical lag. Knowing the lag is part of the job.
Read every record. Flag pre-existing conditions, gaps in treatment, and inconsistencies before the defense does. A six-week treatment gap with no explanation is the single most common reason a strong soft-tissue case loses a third of its value.
If the defense will dispute causation—and in any case with a non-trivial pre-existing condition, they will—line up the treating physician for a causation narrative or, when needed, retain an independent medical expert.

4. Dealing with every adjuster, lienholder, and bill collector

Once representation is on file, the client stops talking to insurance adjusters. That alone is most of what a personal injury lawyer does week-to-week.

The lawyer is the buffer between the client and:

The at-fault driver’s liability adjuster—who is recording statements and looking for inconsistency.
The client’s own UM/UIM and MedPay carrier—useful coverage that adjusters rarely volunteer.
Subrogation departments at the client’s health insurer—including ERISA self-funded plans, where the negotiation rules are completely different.
Medicare and Medicaid lien recovery contractors, when applicable.
Unpaid medical providers threatening collections during treatment.

The dollars saved on the lien side are real money the client keeps. A typical hospital lien negotiated under the Illinois Health Care Services Lien Act (770 ILCS 23) has a statutory cap, but the cap is only the ceiling—competent negotiation routinely brings the actual paid amount well below it.

5. The demand letter and pre-suit negotiation

When treatment has plateaued and the medical picture is stable, the lawyer puts together a demand. A real demand is not a one-page letter quoting bills. It is a case presentation that includes:

A liability narrative that anchors the defendant’s conduct in the specific Illinois standard—typically IPI Civil 60.01 for statutory violation as evidence of negligence, where it applies, plus the specific rule of the road or premises duty in play.
Damages broken into the categories the jury will eventually see on the verdict form (IPI Civil 30.01 et seq.): past and future medical, past and future lost earnings, disability, disfigurement, loss of normal life, and pain and suffering.
Liability themes designed to be repeated in mediation—preventability, on-notice, repeated conduct, foreseeability—because at this stage you are writing for the next reader, who is the carrier’s home-office reviewer.

The pre-suit negotiation has a ceiling. When it runs out, the lawyer files suit.

6. Filing suit, discovery, and depositions

Filing the complaint resets the leverage. In Peoria County Circuit Court, civil cases are routed by case type, and a typical PI matter takes 18 to 30 months from filing to trial setting depending on the courthouse load. The lawyer’s calendar through that window is dominated by:

Written discovery—interrogatories and document requests both directions, with motion practice when the defense stonewalls.
Depositions—your deposition, treating providers, defendant, defendant’s employer, defense expert. The deposition transcript is what every later motion is built from.
Subpoenas—for the records that didn’t come voluntarily, for surveillance video before retention windows close, for prior incident reports when the defendant is a corporate or commercial party.
Expert disclosures—accident reconstruction, biomechanics, life-care planning, vocational rehabilitation, economist—selected to match the case’s actual disputes, not boilerplate.

Discovery is not a waiting period. It is where cases get won or lost.

7. Mediation, pretrial, and settlement

Most Illinois personal injury cases settle. They settle at one of three predictable inflection points: after the plaintiff’s deposition, after the defense expert disclosures, or at court-ordered mediation. The lawyer’s job at each of those points is the same—maximize the case’s apparent trial risk to the defendant while keeping settlement honestly on the table.

Mediation in particular is its own art. The damages presentation that worked in the demand letter is not the presentation that works in front of the mediator. The numbers have to be defended again, with evidence the defense has now seen.

8. Trial—when the case requires it

A small minority of cases—single digits, in most practices—actually try to verdict. The cases that do tend to share common features: a defendant or insurer that has misjudged the case, a damages picture that does not compress easily, or a liability dispute that requires a jury to resolve. Trying a personal injury case in central Illinois is a specific skill set: voir dire that finds the jurors who can hear the case, an opening that previews the proofs without overpromising, direct exams that let the witnesses tell the story, cross-examinations that are short and surgical, and a closing that gives the jury permission to award real numbers.

Drew Parker tried cases in Peoria, Tazewell, McLean, and Knox counties for more than four decades before his retirement. Robert Parker, who joined the firm in 2009 and worked alongside Drew for over a decade, leads the practice today and personally handles every case the firm accepts. Trial preparation begins on the day the file opens, not the week before the call.

9. Resolving the file: liens, distribution, and the close

After verdict or settlement, the file is not done. The lawyer:

Negotiates final lien amounts with health insurers, hospitals, Medicare, and Medicaid contractors. The reduction work here typically returns five-figure dollars to the client on a six-figure case.
Prepares a distribution statement showing every dollar of recovery, every deduction, and the net to the client—itemized line by line.
Handles minor’s-settlement court approval if a child is the claimant, including petition, hearing, and either guardianship or structured-settlement administration.
Closes the file with a final letter and retains the client record for the period required under Illinois Supreme Court Rule 769 and the firm’s record-retention policy.

10. The fee—and why “no recovery, no fee” is the whole structure

Illinois personal injury fees are paid on contingency. The standard rate at Parker & Parker is one-third of the gross recovery before suit and 40 percent if a complaint has to be filed. Costs—court filing fees, deposition transcripts, expert fees, records charges—are advanced by the firm and reimbursed from the recovery. If there is no recovery, the client owes nothing, and that is not a slogan; it is the fee agreement, signed at the first meeting, governed by Illinois Rule of Professional Conduct 1.5(c).

The contingent-fee structure is what aligns the lawyer’s incentives with the client’s: the firm only gets paid when the client gets paid, and the firm’s percentage is the same whether the case is easy or hard, which means there is no economic reason to push a case toward a quick low settlement.

What a personal injury lawyer does not do

For completeness—and because this question gets asked—a personal injury lawyer in Illinois does not:

Handle workers’ compensation claims (different statute, different forum, different fee). Parker & Parker does not take workers’ comp cases.
Pay your medical bills directly. Bills get paid out of the eventual recovery, not before.
Make medical decisions for you. Treatment decisions belong to you and your doctors.
Guarantee an outcome. A reputable Illinois lawyer will give a range based on similar cases—not a number.

How long does the whole process take?

Pre-suit resolution on a moderate Illinois injury case—typically a clear-liability rear-end with completed treatment—runs four to nine months from intake. Cases requiring suit run 18 to 36 months from filing to resolution. Wrongful death and serious-injury cases requiring expert reconstruction can run longer. The single biggest variable is medical resolution—the lawyer cannot put a value on a case while treatment is still active.

When to call a personal injury lawyer in Illinois

Three windows matter:

Within 72 hours of the incident—to lock down evidence before it’s gone.
Before giving a recorded statement to the other side’s insurer—they’re calling for a reason.
Before signing any release—even a property-damage release. Releases are written broadly on purpose.

If you are in central Illinois and trying to figure out whether your situation needs a lawyer, the first conversation is no charge and the answer is sometimes “no”—that’s part of the value. Call (309) 673-0069 or use the contact form on this site.

Frequently Asked Questions

Do I have to pay a personal injury lawyer up front in Illinois?

No. Personal injury representation in Illinois is contingency-based. The lawyer’s fee comes out of the eventual recovery, not out of your pocket up front. If there is no recovery, you owe no fee. Costs advanced during the case are reimbursed from the recovery.

Can I handle a small personal injury claim without a lawyer?

Sometimes. If the injury was minor, treatment was short, fault is undisputed, and the medical bills are below the at-fault driver’s policy limits, a competent person can negotiate the claim directly. The cases where representation pays for itself many times over are the ones with disputed fault, ongoing treatment, lost income, or any commercial defendant.

What is the deadline to file a personal injury lawsuit in Illinois?

Two years from the date of injury for most cases (735 ILCS 5/13-202). Two years from the date of death for wrongful death. One year for claims against an Illinois governmental body. Medical malpractice is two years from discovery, with a four-year outside cap.

What does a personal injury lawyer actually do day-to-day on my case?

Investigate liability, preserve evidence, gather and read every medical record, deal with every insurance adjuster and lienholder, prepare and present the demand, file suit when negotiation stalls, conduct discovery and depositions, prepare the case for mediation or trial, and negotiate the final liens after recovery. The client’s job is to follow medical advice and tell the truth. Everything else is the lawyer’s job.

How much does a personal injury lawyer cost in Illinois?

Standard Illinois contingency fees are one-third before suit, 40 percent after suit is filed, and case costs are advanced by the firm and reimbursed from the recovery. The fee agreement must be in writing under Illinois Rule of Professional Conduct 1.5(c).

What if I was partly at fault for the accident?

Illinois follows modified comparative fault under 735 ILCS 5/2-1116. You can recover as long as you were not more than 50 percent at fault, but your recovery is reduced by your percentage of fault. Liability is rarely as one-sided as either side first claims, and partial fault is one of the most common reasons retaining counsel changes the math.
