What Happens After You File a Personal Injury Lawsuit

Most people picture a lawsuit as a trial. In personal injury practice, filing suit is closer to changing the terms of a negotiation: it opens a formal process for extracting evidence the other side would never hand over voluntarily, imposes deadlines on a claim that was drifting, and puts a real trial date on the calendar that concentrates minds. The large majority of cases still settle. Understanding the stages between filing and that settlement makes the wait comprehensible rather than alarming.

Quick answer: Expect one to three years from filing to resolution. The sequence is pleadings → discovery (written discovery and depositions — the longest phase, often six to eighteen months) → expert disclosure → dispositive motions → mediation → trial. Most cases settle somewhere along that line, frequently after depositions or at mediation, once both sides have finally seen what the evidence actually shows.

The Stages

1. Pleadings

Your attorney files a complaint setting out the claim, and it is formally served on the defendant. The defendant files an answer, admitting or denying each allegation and asserting affirmative defenses — comparative fault, statute of limitations, and so on. Sometimes a motion to dismiss comes first, arguing the complaint fails as a matter of law even if everything in it is true.

Practical note: the defendant’s insurer hires and pays for defense counsel. The named defendant is the other driver; the entity actually running the defense is almost always the insurer.

2. Discovery — where the case is really decided

The longest and most consequential phase. Both sides must disclose evidence:

• Interrogatories — written questions answered in writing under oath
• Requests for production — documents, medical records, photographs, phone records, employment records
• Requests for admission — demands that a party admit or deny specific facts, narrowing what actually has to be proven
• Depositions — sworn oral testimony, transcribed, taken outside court

Discovery routinely takes six months to well over a year. It is also where the defense obtains your prior medical history, which is why the pre-existing condition fight matters so much — see our guide to pre-existing conditions and the aggravation rule for what that fight actually turns on.

3. Your deposition

The stage claimants worry about most, and the one preparation most improves. You answer the defense attorney’s questions under oath, your attorney present, a court reporter transcribing. No judge. Expect the accident itself, your injuries and treatment, your complete medical history, your work, and your day-to-day activities and limitations.

The transcript’s significance is that it locks in your testimony. Anything you say that conflicts with your later trial testimony — or with your medical records — becomes material to challenge your credibility with. The standard guidance from attorneys is consistent and worth repeating: answer only what is asked, do not volunteer, do not guess, say you do not recall when you genuinely do not, and take the time to think before answering. Your attorney will prepare you specifically, and that session matters more than anything you read.

4. Medical examination by the defense

Once you have put your physical condition at issue by suing over it, the defense can generally obtain a medical examination by a physician it selects — commonly called an IME. The report frequently concludes your symptoms are degenerative, pre-existing, or resolved. It is a normal part of a contested case, not a sign something has gone wrong, and it becomes one of the documents the case is argued over.

5. Expert disclosure

Both sides identify expert witnesses and produce their reports — treating physicians and medical experts on causation and prognosis, accident reconstruction where liability is contested, life-care planners and economists in serious cases. Experts are then typically deposed as well. This phase adds real time and real cost, which is part of why case costs climb after filing — see lawyer fees and case costs for how those are handled.

6. Dispositive motions

Most commonly summary judgment: an argument that, on the undisputed facts, one side is entitled to win without a trial. A defense motion typically targets liability or causation. Surviving it is significant — it is often the point where a defendant’s settlement posture changes materially.

7. Mediation

A neutral mediator works with both sides, usually in separate rooms, to find a number. The mediator cannot impose anything, and you can leave without settling. Many courts require it be attempted. A substantial share of cases that get this far settle here, for a straightforward reason: it is frequently the first time both sides confront a neutral third party pointing out the weaknesses in their own case.

8. Trial

A minority of filed cases reach it. Jury selection, opening statements, plaintiff’s case, defense case, closing arguments, verdict. Even here, cases settle on the courthouse steps and during trial. A verdict can also be appealed, which adds substantially more time before anyone is paid.

Why It Takes So Long

• Discovery has statutory response windows — typically 30 days per request, with extensions routine.
• Depositions require coordinating multiple attorneys, parties and witnesses.
• Court dockets are congested, and civil trials yield to criminal cases with speedy-trial rights.
• Experts add months in retention, report preparation and depositions.
• Your treatment has to finish first. A case genuinely cannot be valued before maximum medical improvement, because the final medical picture is the claim.
• Delay is a negotiating tool for the defense, and financial pressure falls asymmetrically on an injured claimant.

What This Means for You Practically

1. Keep treating and keep the records consistent — the case is still being built throughout.
2. Assume everything is discoverable, including social media. Photographs contradicting claimed limitations are a recurring and avoidable problem.
3. Prepare properly for your deposition. It is the single highest-leverage day in the process for a claimant.
4. Expect the defense medical exam and do not treat it as an ambush.
5. Understand the case can settle at any stage — most do, and settling after discovery is not a failure of the process, it is the process working.
6. Budget for time, not just money. A one-to-three-year horizon is normal, and knowing that up front prevents accepting a poor offer out of surprise.
