A civil lawsuit example, step by step, is easiest to follow through a single running scenario. Picture a driver stopped at a red light who gets rear-ended by another driver who failed to brake. The crash causes a whiplash injury, $15,000 in medical bills, $5,000 in vehicle repairs, and three weeks of missed work worth $3,500 in lost wages. Total damages: $23,500. The other driver’s insurance company offers far less, so the injured driver (the Plaintiff) decides to sue the at-fault driver (the Defendant). Every stage below traces back to that collision and those dollar figures.
Most personal injury cases like this one are filed in state court, but state procedure closely tracks the federal rules, so the sequence looks much the same either way.
The Filing Deadline Comes First
Before anything else, there’s a clock. Every lawsuit has a statute of limitations, and missing it almost always destroys the right to sue. For personal injury claims, most states set the deadline somewhere between two and four years from the date of the accident. The clock starts the day the injury happens, not the day its full severity becomes clear.
Some narrow exceptions pause the clock. If the injured person is a minor, the deadline in many states doesn’t start until they turn 18. For injuries that don’t surface right away, like toxic exposure or a device failure, courts may apply a “discovery rule” that starts the clock when the person knew or should have known about the harm. Courts apply these exceptions grudgingly, and the burden is on the injured person to justify the delay.
For our Plaintiff, the deadline is simple. The collision happened on a specific date, the whiplash was immediate, and the clock started that same day.
The Demand Letter and Evidence Package
Many plaintiffs (or their attorneys) send a demand letter to the other side’s insurance company before filing anything in court. The letter describes what happened, attaches supporting evidence, and names a specific dollar figure the plaintiff will accept to resolve the claim. Our Plaintiff’s demand would seek $23,500 and attach:
- The police report documenting the date, location, and circumstances of the crash
- Hospital invoices totaling $15,000 and medical records showing the whiplash diagnosis and treatment
- A letter from the employer confirming $3,500 in missed wages
- Repair estimates or invoices for the $5,000 in vehicle damage
- Photographs of the vehicle damage and the accident scene
- The Defendant’s full legal name and address for court filings and service
A well-documented demand forces the insurer to evaluate the claim with all the evidence in front of them and signals that the plaintiff is ready to litigate. Many cases settle at this stage. Adjusters and defense attorneys probe for gaps, so every dollar claimed should have a receipt, invoice, or written confirmation behind it.
Personal injury plaintiffs who hire attorneys typically do so on a contingency fee, usually 30% to 40% of any recovery. If the Plaintiff eventually settles for $23,500, the attorney’s share would run roughly $7,050 to $9,400.
Drafting and Filing the Complaint
If the demand doesn’t produce a fair offer, the Plaintiff files a complaint, which is the document that officially starts a lawsuit. Federal rules require three things in it: a statement of why the court has authority over the case, a clear description of what happened and why the Defendant is responsible, and a specific request for relief.1Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading State courts use nearly identical requirements.
Our Plaintiff’s complaint would open with a caption identifying the court and the parties. A jurisdiction section would explain why this particular court can hear the case, typically because the accident happened within its geographic boundaries. The body would narrate the rear-end collision, the Defendant’s failure to brake, and the resulting injuries. A closing “prayer for relief” would ask the court to award $23,500 covering medical expenses, repairs, and lost wages.
A claim of this size would normally go to state court. Federal courts generally require either a federal legal question or damages above $75,000 when the parties live in different states.
Filing requires paying the court. In federal court, the base statutory fee is $350, with an administrative fee bringing the total to $405.2Office of the Law Revision Counsel. 28 US Code 1914 – District Court Filing and Miscellaneous Fees State fees vary widely, often from under $100 for small claims to $500 or more for higher-value cases. Many courts allow a fee waiver for plaintiffs who can’t afford it.
Serving the Defendant
Once the complaint is filed, the clerk issues a summons, which formally notifies the Defendant of the lawsuit and the limited time to respond. The summons and complaint must then reach the Defendant through service of process. Federal rules require the person who delivers the papers to be at least 18 and not a party to the case, typically a professional process server, a sheriff’s deputy, or another qualified adult.3Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons
Common methods include handing the papers directly to the Defendant, leaving them with a responsible adult at the Defendant’s home, or delivering them to an authorized agent. The server then files proof of service with the court. When a defendant can’t be found or is actively dodging service, a court may authorize an alternative method, most often service by publication in a local newspaper, but only after traditional attempts have failed. Hiring a process server typically costs $50 to $200 depending on jurisdiction and the number of attempts.
The Defendant’s Response
After service, the Defendant usually has 21 days in federal court (20 to 30 days in most state courts) to respond. The most common response is an answer, in which the Defendant admits or denies each allegation in the complaint. Our Defendant might admit the collision happened but deny that the Plaintiff’s injuries were as serious as claimed.
Instead of answering, the Defendant may file a motion to dismiss, arguing that even if everything in the complaint is true, it doesn’t state a valid legal claim. For a straightforward rear-end collision, that motion would be a long shot. In weaker cases, it can end the lawsuit before it really starts.
A Defendant can also file a counterclaim, suing the Plaintiff back. In a car accident case, that might look like a claim that the Plaintiff shares blame, perhaps by arguing the Plaintiff’s brake lights were out.
Discovery
Once the Defendant responds, both sides enter discovery, where they exchange evidence and information. Discovery is usually the longest and most expensive phase. Its main tools:
- Interrogatories. Written questions the other side must answer under oath. Federal rules cap these at 25 per party unless the court allows more. Our Plaintiff might ask whether the Defendant was texting at the time of the crash or had prior accidents.4Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties
- Requests for production. Formal demands for documents. The Plaintiff could request the Defendant’s vehicle maintenance records to check for faulty brakes. The Defendant could request the Plaintiff’s prior medical records to argue the whiplash was pre-existing.
- Depositions. Live, in-person questioning under oath while a court reporter transcribes everything. Depositions are expensive but powerful, because they lock witnesses into testimony that can be used at trial.
Ignoring Discovery Has Consequences
Stonewalling in discovery carries real penalties. A court can order compliance and impose sanctions that escalate quickly, from making the non-compliant party pay the other side’s legal fees, to barring certain evidence, to striking pleadings.5Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions In extreme cases, the court can enter default judgment against the party who refuses to cooperate, effectively handing the other side a win.
Summary Judgment
Before trial, either side can ask the court for summary judgment. The argument: the key facts aren’t actually in dispute, and the law requires a ruling in that party’s favor on those undisputed facts.6Legal Information Institute. Federal Rules of Civil Procedure Rule 56 – Summary Judgment If the judge agrees, the case ends without a jury.
Our Defendant might seek summary judgment arguing the Plaintiff can’t prove the whiplash was caused by this specific accident. The Plaintiff might seek summary judgment on liability, pointing to the police report and the Defendant’s deposition admitting they didn’t brake in time. Most personal injury cases involve enough factual dispute that summary judgment won’t resolve everything, but the motion forces both sides to show their hand.
Settlement or Trial
The vast majority of civil cases never reach a jury. Trial rates in civil litigation hover around 2% to 3%, though not every remaining case settles; some are dismissed or resolved on procedural grounds. Settlement can happen at any stage: after the demand letter, during discovery, on the courthouse steps. Many cases settle through mediation, where a neutral third party helps both sides negotiate. Our Defendant’s insurer might offer $20,000 during mediation, and the Plaintiff would weigh that guaranteed amount against the uncertainty, delay, and cost of trial.
If no agreement is reached, the case goes to trial. A judge or jury hears testimony, reviews evidence, and answers two questions: is the Defendant liable, and if so, for how much? Our Plaintiff would present the police report, medical records, and testimony about the collision. The Defendant would challenge the extent of injuries and argue for less. The trial ends with a verdict, and the court enters a final judgment, which is the official, enforceable order resolving the case. The judgment may include damages, court costs, and post-judgment interest.
Appeals
Losing at trial doesn’t necessarily end things. The losing party can appeal, arguing that the trial judge made a legal error, such as applying the wrong legal standard, admitting evidence that should have been excluded, or giving the jury incorrect instructions. Appeals courts don’t re-hear testimony or re-weigh evidence; they review the trial court’s legal decisions.
The appeal window is tight. In federal court, a party generally has 30 days from entry of the final judgment to file a notice of appeal. State deadlines vary but are similarly short. Missing the deadline almost always forfeits the right to appeal regardless of how strong the arguments would have been. Appeals also take months or years and add significant cost, so most parties weigh the odds carefully.
Collecting the Judgment
Winning a judgment and actually getting paid are two different things. If the Defendant or their insurance company pays voluntarily, the process is easy. When a defendant ignores a judgment, the plaintiff has to use enforcement tools. Wage garnishment redirects part of the Defendant’s paycheck to the Plaintiff. A bank levy seizes funds directly from the Defendant’s accounts. In some cases a court can order the sheriff to seize and sell the Defendant’s property to satisfy the debt.
Before using any of these tools, a plaintiff often needs post-judgment discovery, a second round of investigation to locate the Defendant’s money and assets. Courts can compel defendants to answer questions about their finances, and ignoring those orders risks a contempt finding. Judgments don’t last forever either. Most states set an expiration window, commonly between five and twenty years, though judgments can usually be renewed before they lapse. A judgment is only as valuable as the defendant’s ability to pay it.
