In a personal injury case, litigation is the formal process of resolving your claim through the court system once insurance negotiations have stalled or failed. It runs from filing a lawsuit through discovery, pre-trial motions, and — if the case doesn’t settle first — a trial and verdict. Only about 3 to 5 percent of personal injury cases actually reach a courtroom verdict; the vast majority settle somewhere during litigation itself. Depending on the complexity of your injuries and how aggressively the other side fights, the process can run anywhere from several months to well over a year.
Here’s what each stage actually involves, and what you should expect at each one.
Filing Deadlines Come First
Litigation can’t begin unless you still have the legal right to sue. Every state sets a deadline called a statute of limitations, and if you miss it, your case is dead no matter how strong your evidence is. Once that window closes, the defendant can ask the court to throw out your lawsuit and the court will almost certainly agree. Insurers know this too. Once your deadline passes, they have no reason to offer you anything.
For personal injury claims, statutes of limitations across the country range from one to six years, with two years being the most common. A few narrow exceptions pause or extend that clock. The most important is the discovery rule: if your injury wasn’t immediately obvious — delayed symptoms from a car crash, or a surgical instrument left inside you that doesn’t cause problems for months — the deadline may start when you discovered the injury or reasonably should have, rather than the date of the incident. Deadlines are also typically paused for minors until they turn 18, and for cases where the defendant actively concealed wrongdoing.
One boundary worth flagging: if the party that injured you is a government agency or employee, the rules tighten considerably, with shorter notice requirements and mandatory administrative claims before you can even file suit. If a government entity is involved, get legal advice early.
How the Lawsuit Starts
A personal injury lawsuit begins when you, the plaintiff, file a complaint with the court. The complaint lays out what happened, identifies who you believe is at fault, explains the legal basis for holding them responsible, and describes the harm you suffered. Along with the complaint, the court issues a summons directed at the defendant.
The summons is more than a notification. It names the court and parties, states how long the defendant has to respond, and warns that failing to respond will result in a default judgment. The summons and complaint must then be formally delivered to the defendant through a process called service. In federal court, if the defendant isn’t properly served within 90 days of filing, the court can dismiss the case.1Cornell Law Institute. Federal Rules of Civil Procedure Rule 4
Once served, the defendant has a limited window to respond. In federal court, that window is 21 days to file either an answer, which responds to each allegation, or a motion to dismiss, which argues the case should be thrown out for a legal deficiency. State court deadlines vary but typically fall in the 20-to-30-day range. If the defendant waives formal service voluntarily, the federal response deadline extends to 60 days.2Cornell Law Institute.

Discovery: Where Most of the Work Happens
After both sides have filed their initial paperwork, the case enters discovery. This is the longest and often most expensive phase of litigation, and it’s where each side compels the other to hand over evidence, answer questions, and sit for recorded testimony. The entire point is to eliminate surprises. By the time discovery ends, both sides should have a clear picture of what the evidence actually shows, which is precisely why so many cases settle during or immediately after this phase.
The Main Discovery Tools
Each side has several formal mechanisms to extract information from the other.
Interrogatories are written questions the other side must answer in writing, under oath. They’re useful for nailing down basic facts: employment history, insurance policy details, the names of witnesses.3Cornell Law Institute. Federal Rules of Civil Procedure Rule 33
Requests for production are formal demands for documents and records relevant to the case. In a personal injury claim, expect requests for medical records, bills, accident reports, photos, and insurance policies.
Depositions are live, sworn testimony given outside the courtroom, usually in a lawyer’s office with a court reporter transcribing everything. Either side can depose parties, witnesses, treating doctors, or anyone else with relevant knowledge. Depositions are often where cases are won or lost. A witness who falls apart under questioning changes the settlement math fast.4Cornell Law Institute. Federal Rules of Civil Procedure Rule 30
Requests for admission are written statements asking the other side to admit or deny specific facts. Any fact that’s admitted is settled for the rest of the case, which narrows what actually needs to be argued at trial.5Cornell Law Institute. Federal Rules of Civil Procedure Rule 36
Medical Exams and Expert Witnesses
In personal injury cases, the defendant will almost certainly ask the court to order you to undergo a physical examination by a doctor of their choosing. The court can grant this when your physical or mental condition is genuinely at issue and there’s good cause for the exam.6Cornell Law Institute. Federal Rules of Civil Procedure Rule 35 These are called “independent medical examinations,” though plaintiff attorneys will tell you there’s nothing independent about a doctor hired by the defense. Refusing to attend a court-ordered exam can still result in sanctions or dismissal of your case.
Both sides also typically retain expert witnesses during discovery. Unlike ordinary witnesses who describe what they personally saw, experts offer opinions based on specialized knowledge. In a personal injury case, that commonly includes medical professionals who testify about the nature and permanence of your injuries, accident reconstruction specialists who explain how the incident happened and who was at fault, and economists who calculate the long-term financial cost of your injuries, including future lost earnings and medical care. Each side must disclose its experts and provide written reports detailing their opinions and the basis for those conclusions.
Pre-Trial Motions and Conferences
Once discovery wraps up, the case enters a phase heavy on legal maneuvering. Both sides file motions, which are formal requests asking the judge to rule on specific issues before trial begins. This is where a case can end abruptly or have its scope dramatically narrowed.
The most consequential motion is a request for summary judgment. This asks the judge to decide the case, or part of it, without a trial, on the grounds that there’s no genuine dispute about the key facts and the law clearly favors one side.7Cornell Law Institute. Federal Rules of Civil Procedure Rule 56 If the defendant can show that even taking all the evidence in your favor, no reasonable jury could find them liable, the judge can end the case right there. Plaintiffs can file these motions too, though it’s less common in personal injury cases where facts are usually contested.
Other common pre-trial motions include motions to compel discovery, which force a party who’s been dragging their feet to turn over requested information, and motions in limine, which ask the judge to exclude certain evidence from trial. For example, a plaintiff might move to prevent the jury from hearing about their prior unrelated injuries, or a defendant might try to exclude evidence of their insurance coverage.
The judge also holds pretrial conferences with both attorneys. These set a trial schedule, manage any remaining disputes, and push the parties toward settlement.8Cornell Law Institute. Federal Rules of Civil Procedure Rule 16 Many judges are blunt at these conferences about the strengths and weaknesses of each side’s case, which frequently motivates realistic settlement offers.
Settlement and Mediation Keep Running Alongside
Filing a lawsuit doesn’t lock you into a trial. Settlement negotiations continue throughout the litigation process, and most cases resolve this way. The further a case progresses through discovery and motions, the more both sides understand the evidence, which often makes it easier to agree on a number.
Many courts require the parties to attempt mediation or another form of alternative dispute resolution before allowing a case to go to trial. Mediation involves a neutral third party who works with both sides to negotiate a resolution. The mediator doesn’t make a decision; if you can’t reach an agreement, you keep your right to go to trial. But mediation succeeds more often than people expect, partly because a skilled mediator can reality-test both sides in ways their own attorneys may not.
A settlement reached during litigation is binding once both parties sign the agreement and the court approves it. You give up your right to pursue further claims from the same incident in exchange for a guaranteed payment, avoiding the risk and expense of trial.
If the Case Goes to Trial
If settlement fails, the case goes to trial. This is the stage most people picture when they hear the word “litigation,” but fewer than 5 percent of personal injury cases get here.
The trial begins with jury selection, called voir dire, where attorneys for both sides question potential jurors to identify biases and shape a panel they believe will be fair to their client. After opening statements, the plaintiff presents their case first, calling witnesses and introducing evidence such as medical records, photographs, and expert testimony. The defendant’s attorney cross-examines each witness. After the plaintiff rests, the defense presents its own case, which the plaintiff’s attorney then cross-examines.
One thing that often surprises people: the burden of proof in a personal injury trial is far lower than in a criminal case. You don’t need to prove your case “beyond a reasonable doubt.” You must show that your version of events is more likely than not, a standard called preponderance of the evidence. Think of it as tipping the scale just past the 50-percent mark. This lower bar is one reason injured plaintiffs can sometimes win cases that seem like close calls on the facts.
After closing arguments, the judge instructs the jury on the applicable law. The jury deliberates privately and returns a verdict. If the verdict favors the plaintiff, the jury also determines the amount of damages, and the judge formally enters the verdict as a judgment of the court.
What You’re Actually Litigating For
Personal injury damages fall into three categories, and understanding them puts the rest of the process in perspective.
Economic damages cover measurable financial losses: medical bills past and future, lost wages, reduced earning capacity, property damage, and out-of-pocket expenses like transportation to medical appointments. These are backed by documentation, which makes them relatively straightforward to prove.
Non-economic damages compensate for harms that don’t come with a receipt — physical pain, emotional distress, loss of enjoyment of life, and similar impacts. Juries have wide discretion in valuing these, which is one reason trial outcomes can be unpredictable.
Punitive damages are available only when the defendant’s conduct was especially egregious, involving malice, fraud, or extreme recklessness. They aren’t meant to compensate you; they’re meant to punish the defendant and deter similar behavior. Most personal injury cases don’t involve them.
What Litigation Costs You
Most personal injury attorneys work on contingency fees, meaning they collect a percentage of whatever you recover and nothing if you lose. The standard range is roughly one-third of the recovery if the case settles before trial, increasing to around 40 percent if the case goes through trial or appeal. The specific percentage should be spelled out in a written fee agreement before representation begins. One detail worth asking about: whether the attorney calculates their percentage before or after deducting litigation expenses, since the answer meaningfully changes your take-home amount.
Beyond attorney fees, litigation generates its own costs. Court filing fees vary widely by jurisdiction, anywhere from under $200 to over $1,000 depending on the court and the amount you’re claiming. Expert witnesses charge for their time reviewing records, preparing reports, and testifying. Deposition transcripts, medical record requests, and copying costs add up. In most contingency arrangements, these expenses are advanced by the attorney and deducted from your recovery, but confirm this in your fee agreement. If the case is lost, some arrangements require you to repay those expenses while others do not.
After the Verdict
A verdict doesn’t always end the litigation. The losing party can appeal to a higher court, arguing that legal errors during the trial affected the outcome.9United States Courts. Appeals An appeal isn’t a second trial. The appellate court reviews the trial record for mistakes of law, not factual disputes. Appeals can add months or years to the timeline and don’t always succeed, but they’re common enough that you should factor the possibility into your expectations.
If you win and the defendant doesn’t voluntarily pay, you may need to take enforcement steps such as garnishing wages, seizing assets, or placing liens on property. Once the full judgment amount is paid, the case formally closes with a satisfaction of judgment filed with the court. If the defendant lacks the resources to pay, collecting on even a favorable judgment can become its own prolonged battle, which is one of the reasons a guaranteed settlement often looks more attractive than rolling the dice at trial.
