Most personal injury claims never become lawsuits. They are negotiated with an insurer and settled, and the injured person never sees a courtroom. But when negotiation fails, the claim crosses into litigation — and almost everything about it changes: the timeline, the formality, the cost, and who controls the pace.
Here is what actually happens, stage by stage, and what it means for you.
Key Takeaways
- Filing suit does not mean going to trial — the large majority of filed cases still settle, often after key evidence emerges.
- The statute of limitations is the hard deadline: filing preserves the claim, and missing it ends it regardless of merit.
- Discovery is the longest and most demanding phase, and it is where cases are usually won or lost.
- Your medical history, social media and daily activities become subject to scrutiny once suit is filed.
- Litigation costs are advanced in most contingency arrangements but come out of the recovery — ask how that works before filing.
Why a Claim Becomes a Lawsuit
Four reasons account for most filings. The insurer disputes liability. The insurer accepts liability but offers far below what the injuries justify. The insurer denies that the treatment relates to an accident at all, usually citing a pre-existing condition or a gap in treatment. Or the statute of limitations is approaching and negotiation has not concluded — filing simply preserves the right to proceed.
That last category is common and misunderstood. A suit filed to protect a deadline does not mean negotiations have collapsed; they usually continue alongside the litigation.
Stage 1: Filing and Service
Your lawyer files a complaint setting out the parties, the facts, the legal claims and the relief sought, in a court with jurisdiction over the defendant and the subject matter. The defendant must then be formally served, and has a set period — commonly 20 to 30 days depending on the court — to respond.
The answer typically denies most allegations and asserts affirmative defences: comparative fault, failure to mitigate damages, pre-existing conditions, or an argument that the limitation period has run. Defendants may also file motions to dismiss on legal grounds before answering, or bring third parties into the case.
Nothing about this stage should alarm you. Blanket denials are standard practice and not a signal about the strength of your case.
Stage 2: Discovery
This is the longest phase, frequently running six months to two years, and it is where an injury lawsuit is genuinely built or dismantled. Both sides are entitled to obtain evidence from each other.
Written discovery includes interrogatories — written questions answered under oath — requests for documents, and requests for admission. Expect to produce medical records, employment and wage records, tax returns where lost income is claimed, and often years of prior medical history.
Depositions are sworn testimony taken outside court, recorded by a court reporter and often on video. You will be deposed, as will the defendant, treating physicians, witnesses and experts. Your deposition is the single most important day of the case for most plaintiffs, and your lawyer should prepare you thoroughly. The rules are simple and hard to follow under pressure: tell the truth, answer only what is asked, say you do not know when you do not, and never guess.
Independent medical examinations are examinations by a physician retained by the defence. The doctor is not treating you and the report frequently minimises the injury or attributes it to something else. Your lawyer prepares you for it and may obtain a rebuttal opinion.
Expert disclosure follows: accident reconstruction, treating and retained medical experts, vocational and economic experts, and life care planners in serious cases.
Assume surveillance. Defence investigators photograph plaintiffs, and social media is reviewed as a matter of course. A single photograph of you lifting something at a family gathering can be used to argue your restrictions are exaggerated — even if you paid for it for three days afterwards.
Stage 3: Motions
After discovery, defendants commonly move for summary judgment, arguing that even on the facts most favourable to you there is no genuine dispute requiring a trial. Surviving that motion is a significant milestone and frequently prompts a meaningful improvement in settlement offers.
Motions in limine follow closer to trial, determining what evidence the jury will and will not hear — prior injuries, insurance, subsequent remedial measures, expert methodology. These rulings can shape the case as much as the underlying facts.
Stage 4: Mediation and Settlement
Many courts require mediation before trial. A neutral mediator meets with both sides, usually in separate rooms, and works toward a negotiated resolution. Mediation succeeds more often than people expect, because by that point both sides have seen the evidence and the uncertainty of a verdict is concrete rather than theoretical.
The decision to accept or reject any offer is yours alone. Your lawyer advises; the choice is not theirs to make. Weigh the offer against the realistic range of verdicts, the risk of losing entirely, the additional cost of trial, and the delay — appeals can add a year or more even after a win.
Stage 5: Trial
A small fraction of filed cases reach trial. Those that do proceed through jury selection, opening statements, the plaintiff’s case, the defence case, closing arguments, jury instructions and deliberation. Most personal injury trials run several days to a few weeks.
The jury decides liability, allocates comparative fault, and determines damages. A verdict is not necessarily the end — post-trial motions and appeals can follow, and collecting a judgment against an underinsured defendant is a separate practical problem.
What Litigation Costs
Contingency fee percentages commonly increase once suit is filed, reflecting the additional work. Separately, case costs — filing fees, deposition transcripts, expert witness fees, records retrieval, exhibits — are advanced by the firm in most arrangements and reimbursed from the recovery. Expert fees in a serious case can run into tens of thousands of dollars.
Ask two questions before filing: how the fee changes at each stage, and what happens to costs if the case is lost. Get the answers in writing. Understanding this early is part of compensation rather than discovering it at settlement.
Frequently Asked Questions
Will I definitely have to go to court?
Most likely not for a trial, but you should expect to attend a deposition, possibly a medical examination, and mediation. The great majority of filed cases settle before trial.
How long does it take?
Commonly one to three years from filing to resolution, depending on the court’s backlog, the complexity of the injuries and how hard the case is fought. Some resolve much faster.
Can I still settle after filing?
Yes, at any point — before discovery, after depositions, at mediation, on the courthouse steps, and even during trial before the verdict.
What if I lose?
Under a contingency agreement you owe no attorney fee, but whether you owe case costs depends on your agreement. Some jurisdictions and some procedural rules can also expose a losing party to certain of the other side’s costs. Clarify this before filing.
Does my whole medical history become discoverable?
Not everything, but records relating to the injured body parts and to conditions the defence argues are relevant generally are. Your lawyer can object to overbroad requests, though bringing a claim does waive privacy over genuinely relevant records.
The Bottom Line
Filing suit is a strategic step rather than a declaration of war. It preserves the deadline, unlocks discovery, and forces the other side to evaluate the case on evidence rather than on their own assessment of your file. Most cases still settle — usually on better terms than were available before.
