A personal injury lawsuit works by moving through a set sequence: you file a complaint in court, formally serve the defendant, exchange evidence during discovery, negotiate a settlement, and take the case to trial only if no agreement is reached. Roughly 95 to 97 percent of civil cases resolve before trial through settlement or dismissal, so most personal injury claims never see a jury. Understanding what happens at each stage tells you where the leverage sits and why the process takes as long as it does.
The Deadline That Comes Before Everything Else
Before any lawsuit can start, you have to be inside the statute of limitations — a hard deadline that varies by state. In most states, you have between one and three years from the date of injury to file, though a handful allow up to six years for certain claims. Miss the window and the court will refuse to hear the case regardless of how strong it is.
The clock usually starts on the day of the injury, but exceptions can shift that date. Under the discovery rule, the deadline may not begin until you knew or reasonably should have known about the injury, which comes up often in medical malpractice cases where a surgical error takes months to produce symptoms. For minors, most states pause the clock until the child turns 18. Claims against government agencies frequently require a formal notice of claim within as few as 60 to 180 days, well before the standard filing deadline. If a government entity at any level is involved, check those notice requirements immediately.
Filing the Complaint
The lawsuit officially begins when you file a document called a complaint with the appropriate court. The complaint identifies you and the defendant, describes what happened, explains why the defendant is legally responsible, and states the compensation you’re seeking. Federal courts and most state courts provide standardized complaint forms for common case types, including negligence claims. 1United States Courts. Civil Forms
The complaint must include enough factual detail to put the defendant on notice of what they allegedly did wrong and how it caused your injuries. You list economic losses — medical bills, lost wages, property damage — as specifically as possible, along with non-economic harms like pain, reduced mobility, or emotional distress. Filing requires paying a court fee, which runs around $405 in federal court and varies in state courts. If you can’t afford the fee, most courts allow you to apply for a fee waiver based on income.
Serving the Defendant and Getting a Response
Filing is only half the equation. You must formally deliver copies of the complaint and a court-issued summons to the defendant through service of process. This is a constitutional requirement that ensures the defendant actually knows about the lawsuit and has a fair chance to respond. 2Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons
You can’t serve the papers yourself. Most plaintiffs hire a professional process server or ask the local sheriff’s office to make the delivery. Process server fees typically range from $20 to $100 per job. After delivery, a proof of service document gets filed with the court confirming the defendant was properly served. If service isn’t completed within the timeframe the court sets, the case can be dismissed.
Once served, the defendant has a limited window to respond. In federal court, the deadline is 21 days after service. 3United States Courts. Federal Rules of Civil Procedure State courts commonly allow 30 days, though this varies. The response usually takes one of three forms.
Most defendants file an answer, which addresses each allegation in the complaint by admitting it, denying it, or stating they lack enough information to respond. The answer also raises any affirmative defenses — arguments that, even if the facts are true, the defendant shouldn’t be liable. Common affirmative defenses in personal injury cases include claiming you were partly or entirely at fault, that you assumed the risk of the activity, or that you waited too long to file.
Instead of answering, some defendants file a motion to dismiss, arguing the case has a fatal legal defect, such as the wrong court, an expired statute of limitations, or a complaint that fails to state a valid claim even if every fact alleged is true. If the defendant ignores the lawsuit entirely and misses the response deadline, you can ask the court to enter a default judgment in your favor.
Discovery
Discovery is where both sides lay their cards on the table. Before anyone can spring evidence at trial, the rules require a structured exchange of information so each side can evaluate what the other has. This phase often takes months and accounts for the bulk of litigation time and expense.
Initial Disclosures and Written Discovery
Federal rules require each party to hand over basic information without being asked: the names of people with relevant knowledge, copies of key documents, a computation of claimed damages, and any applicable insurance agreements. 4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose After that exchange, the formal discovery tools kick in.
Interrogatories are written questions each side sends the other, answered under oath and typically limited to 25 in federal court. 5Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties Requests for production demand documents and tangible evidence: medical records, internal emails, maintenance logs, surveillance footage, or the actual equipment involved in an accident. The responding party generally has 30 days to comply or object.
Depositions and Experts
Depositions are live question-and-answer sessions conducted under oath, with a court reporter transcribing every word. Attorneys use depositions to pin down exactly what the plaintiff, defendant, and eyewitnesses will say at trial. Changing your story after a deposition is one of the fastest ways to destroy credibility with a jury.
Expert witnesses play a central role in most personal injury cases. Medical experts testify about the severity of your injuries and future treatment needs. Accident reconstructionists explain how the incident happened. Economists calculate the present value of your lost future earnings. Physician experts commonly bill between $350 and $800 per hour for litigation work, and specialists in niche fields can charge more. The party that retains the expert pays those fees regardless of the outcome.
The Independent Medical Examination
The defense will almost certainly ask you to undergo an independent medical examination, where a doctor chosen and paid by the defendant’s insurance company evaluates your injuries. The court can order this examination when your physical or mental condition is genuinely in dispute. 6Legal Information Institute. Federal Rules of Civil Procedure Rule 35 – Physical and Mental Examinations Refusing to attend can result in sanctions, including having your claims limited or dismissed.
Keep in mind that this doctor works for the other side. The examination will focus on the body parts you claim were injured, and the doctor will write a report that goes straight to the defense attorney. Be truthful and describe your symptoms accurately, but don’t volunteer unrelated information or make small talk that could be taken out of context.
Settlement Negotiations
Settlement talks can happen at any point. Sometimes before the lawsuit is even filed, sometimes on the courthouse steps during trial. The process typically starts with a demand letter sent to the defendant’s insurance carrier, laying out the full scope of your injuries, treatment, lost income, and a specific dollar amount you’ll accept to resolve the case. The insurer almost always counters with a lower number, and negotiations go back and forth from there.
If direct negotiations stall, the court may order mediation, where a neutral third party works with both sides to find a compromise. The mediator doesn’t decide anything; they facilitate conversation and help each side see the weaknesses in their position. Only about 3 to 5 percent of personal injury cases ever reach trial, which tells you settlement is the expected outcome. The threat of trial is what gives settlement negotiations their teeth. An insurance company that knows you’re prepared to go before a jury will negotiate differently than one that senses you’ll take any offer to avoid the courtroom.
How Fault Affects What You Recover
If you were partially responsible for the accident, that doesn’t necessarily destroy your claim, but it will almost certainly reduce what you recover. The vast majority of states use some version of comparative negligence, which reduces your damages in proportion to your share of fault. If a jury finds you 20 percent at fault for a $100,000 injury, you collect $80,000.
About 11 states follow pure comparative negligence, allowing you to recover something even if you were 99 percent at fault. Roughly 32 states use a modified version that cuts off recovery entirely once your fault hits either 50 or 51 percent, depending on the state. Five jurisdictions still follow the old contributory negligence rule, which bars recovery completely if you bear any fault at all. Which system applies shapes every settlement decision.
Lump Sum or Structured Payments
Most settlements pay out as a single lump sum, giving you immediate access to the full amount. For larger recoveries, a structured settlement spreads payments over months or years through an annuity. Structured settlements can generate interest that increases the total value beyond what a lump sum would provide, and they protect against the risk of spending a large recovery too quickly. The tradeoff is reduced flexibility. You generally can’t change the payment schedule later if your circumstances shift.
Trial
If no settlement materializes, the case goes to trial. You bear the burden of proof, and the standard in civil cases is “preponderance of the evidence” — you need to show it’s more likely than not that the defendant’s conduct caused your injuries. That’s a significantly lower bar than the “beyond a reasonable doubt” standard used in criminal cases, but it still means you need credible evidence supporting every element of your claim.
The trial opens with jury selection, a process called voir dire where attorneys and the judge question prospective jurors about potential biases. Attorneys can strike jurors for specific reasons, like a personal connection to the case, or use a limited number of peremptory challenges to remove jurors without stating a reason. 7United States Courts. Juror Selection Process
After opening statements, the plaintiff presents evidence first, calling witnesses, introducing documents and medical records, and having expert witnesses explain technical issues. The defense cross-examines each witness, then presents its own case. After closing arguments, the jury deliberates and returns a verdict. If the jury finds in your favor, the verdict specifies the total damages awarded. The judge then enters a formal judgment based on that verdict.
After the Verdict
A trial verdict doesn’t always end the case. The losing side has 28 days to file several types of post-trial motions: a motion for a new trial arguing that errors affected the outcome, a motion to alter or amend the judgment, or a renewed motion for judgment as a matter of law arguing the evidence couldn’t support the verdict. These motions pause the clock on appeals.
If post-trial motions fail or aren’t filed, either party can appeal the judgment to a higher court. The deadline to file a notice of appeal in federal court is 30 days after entry of judgment in most civil cases, or 60 days when the federal government is a party. An appeal doesn’t retry the facts. It asks the appellate court to review whether the trial judge made legal errors that affected the outcome. Appeals routinely take a year or more to resolve, which is worth factoring into any post-verdict settlement discussion. Sometimes a defendant who lost at trial will offer a guaranteed payment in exchange for the plaintiff dropping the appeal, and vice versa.
What You Can Recover
Personal injury damages fall into three categories, and each behaves differently in negotiation and at trial.
- Economic damages are your measurable financial losses: medical bills, future treatment costs, lost wages, reduced earning capacity, and property damage. They’re calculated from receipts, bills, pay records, and expert projections.
- Non-economic damages compensate for harms without a price tag: physical pain, emotional distress, loss of enjoyment of life, disfigurement, and loss of companionship. These are harder to quantify and often become the most contested part of the case.
- Punitive damages are awarded in cases involving especially reckless or intentional conduct, meant to punish the defendant rather than compensate you. Courts reserve them for egregious behavior, and many states cap the amount that can be awarded.
Your complaint should identify both economic and non-economic damages as specifically as possible. Vague damage claims invite lowball settlement offers because the insurer can’t evaluate what the case is actually worth.
What You Actually Keep
The number on the settlement check isn’t the number that lands in your account. Three things come out of it: attorney fees, liens, and in some cases taxes.
Most personal injury lawyers work on a contingency fee basis, collecting a percentage of your recovery only if you win. The standard contingency fee is around 33 percent of the settlement or verdict, often rising to 40 percent if the case goes to trial. If you lose, you owe no attorney fees, though you may still be responsible for out-of-pocket litigation costs like filing fees, expert witness charges, and deposition transcripts. Before signing a fee agreement, ask exactly what costs get deducted from your share and whether those costs come out before or after the attorney’s percentage is calculated. That distinction alone can shift your take-home amount by thousands of dollars.
Before you receive settlement funds, several parties may have a legal claim to a portion of the money. If your health insurer paid for accident-related medical treatment, it can assert a subrogation lien to recover those costs from your settlement. Government programs like Medicare and Medicaid have even stronger recovery rights. Medicare makes what it calls “conditional payments” for your treatment, and federal law requires that those payments be repaid from any settlement or judgment you receive. 8Centers for Medicare & Medicaid Services. Medicare’s Recovery Process Failing to repay Medicare can result in the government pursuing double damages. Your attorney can often negotiate lien amounts down, particularly with private insurers, but government liens are harder to reduce. A $200,000 settlement with $60,000 in liens and a 33 percent attorney fee leaves you about $74,000.
Taxes take another slice, depending on what the money compensates. Under the Internal Revenue Code, damages received for personal physical injuries or physical sickness are excluded from gross income, so you owe no federal income tax on that portion. 9Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness This exclusion covers compensatory damages including lost wages, as long as the recovery is “on account of” a physical injury.
The rules change sharply for non-physical claims. Damages for emotional distress that doesn’t stem from a physical injury are taxable income, with one narrow exception: you can exclude amounts that reimburse medical expenses for treating the emotional distress, as long as you didn’t already deduct those expenses on a prior tax return. 10Internal Revenue Service. Tax Implications of Settlements and Judgments Punitive damages are taxable regardless of whether the underlying injury was physical. If your settlement includes multiple damage categories, how the settlement agreement allocates the money between physical injury compensation and other categories directly affects your tax bill, which is one reason to negotiate that allocation carefully before signing.
