Civil litigation is the court process a private person or organization uses to resolve a non-criminal dispute with another party, almost always by seeking money for harm the other side caused. It is driven by the injured party, not the government, and it moves through a predictable sequence: filing a complaint, exchanging evidence, trying to settle, and, if nothing else resolves it, going to trial. Most cases never reach that last step.
Who Sues, Who Gets Sued, and What You Can Win
Every civil case has at least two sides. The plaintiff files the lawsuit. The defendant is the party accused of causing harm or breaking an obligation. A single case can have multiple plaintiffs, multiple defendants, or both.
The point of filing is to get a remedy. The most common one is monetary damages, which compensate the plaintiff for losses like medical expenses, lost income, or property damage. Courts can also issue an injunction, which orders the defendant to do something or stop doing something. A third option is a declaratory judgment, which simply states the parties’ legal rights in a situation without awarding damages or ordering any conduct.1United States Courts. Civil Cases
What Kinds of Disputes Go Through Civil Litigation
The range is wide. Tort cases are among the most common. A tort is a civil wrong that injures someone, and the injured person sues whoever is responsible. This covers personal injury from car accidents, medical malpractice, slip-and-fall incidents, and defective products, along with defamation, fraud, and negligence claims generally.
Contract disputes are the other major category. When one party fails to hold up their end of an agreement, the other can sue for breach. Examples include a business that fails to deliver goods, a contractor who walks off a project, or a tenant who violates lease terms. Property disputes cover ownership questions, boundary lines, easements, and landlord-tenant conflicts. Employment claims, family law matters, and intellectual property cases also run through the civil system.
The Deadline That Can End Your Case Before It Starts
Every civil claim has a statute of limitations, a window of time after the harm during which you can file. Miss it and the court will almost certainly dismiss the case no matter how strong it is.
These deadlines vary by claim type and by jurisdiction. Personal injury windows commonly run anywhere from one to six years, and written contract claims often get longer. For federal claims created by an Act of Congress, the default is four years unless the specific statute says otherwise. Some situations toll, or pause, the clock, such as when the injured person is a minor or when fraud is not immediately discoverable. The single most common reason people lose the right to sue on a valid claim is simply waiting too long, so pin your deadline down early.
How a Civil Case Moves Through the Courts
Pleadings
A case starts with pleadings, where each side puts its position on paper. The plaintiff files a complaint describing what happened, how the defendant caused harm, why the court has authority to hear the case, and what remedy the plaintiff wants. The plaintiff also pays a filing fee, though someone who cannot afford it can ask the court to waive it.1United States Courts. Civil Cases A copy of the complaint and a summons are then formally delivered to the defendant through service.
Once served, the defendant generally has 21 days to respond in federal court. If the defendant waived formal service, the deadline extends to 60 days.2Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections The response, called an answer, addresses each allegation by admitting it, denying it, or claiming insufficient knowledge. The defendant can also raise affirmative defenses, which are legal reasons the plaintiff should lose even if the facts are true.
Instead of answering, the defendant may file a motion to dismiss, arguing the case has a fatal flaw. The most common version argues that even if everything in the complaint were true, it would not add up to a valid legal claim. If the court agrees, the case ends. If not, the defendant files an answer and the case moves forward.2Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections A defendant with their own claim against the plaintiff can also file a counterclaim; if it arises from the same underlying dispute, the defendant is generally required to raise it then or lose the right to bring it later.
Discovery
After pleadings, the case enters discovery, usually the longest and most expensive phase. Both sides investigate the facts by gathering evidence from each other and from third parties. This is where cases are actually built. The main tools are:
- Interrogatories, which are written questions the other side must answer in writing and under oath. Federal rules cap each side at 25 without court permission.3Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties
- Requests for production, which are formal demands for documents, electronic data, or other tangible items. The responding party has 30 days to produce or object.4Legal Information Institute. Federal Rules of Civil Procedure Rule 34 – Producing Documents, Electronically Stored Information, and Tangible Things
- Depositions, which are live, in-person questioning of witnesses or parties under oath, recorded by a court reporter.5Legal Information Institute. Federal Rules of Civil Procedure Rule 30 – Depositions by Oral Examination
In cases involving technical issues, parties often hire expert witnesses, whose opinions and qualifications must be disclosed in a written report well before trial.6Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery
Summary Judgment
After discovery closes, either side can ask the court to decide the case without a trial by filing a motion for summary judgment. The court grants it when there is no genuine dispute about the key facts and the moving party is entitled to win as a matter of law.7Legal Information Institute. Federal Rules of Civil Procedure Rule 56 – Summary Judgment If the evidence is so one-sided that no reasonable jury could find for the other party, the judge can end the case right there.
These motions are common and consequential. Many cases that survived the pleadings stage end here. If a real factual disagreement remains, the motion gets denied and the case heads to trial.
Settlement and Alternative Dispute Resolution
Most civil cases never reach a verdict. Estimates vary, but only around one to two percent of federal civil cases are resolved at trial. The rest settle, get dismissed, or go through alternative dispute resolution.
Settlement can happen at any point, from before filing to the middle of trial. It is an agreement between the parties to resolve the dispute on their own terms, usually with a payment in exchange for dropping the case. It avoids the unpredictability of a verdict and the cost of a trial.
Many courts encourage or require parties to try ADR first. Mediation is the most common form, where a neutral third party helps the sides negotiate but cannot impose a decision. Arbitration goes further: a neutral arbitrator hears evidence and issues a decision. Binding arbitration produces a final, enforceable result; non-binding arbitration gives an advisory opinion the parties can accept or reject. Many contracts include clauses requiring disputes to go to arbitration rather than court, which changes how the whole process unfolds.
Trial
If nothing resolves the case, it goes to trial. Both sides present evidence and arguments to a judge or a jury. Each side calls witnesses, cross-examines the other side’s witnesses, and introduces documents and physical evidence. The plaintiff carries the burden of proof throughout, meaning the plaintiff must persuade the fact-finder that their version is more likely true than not.
After closing arguments, the judge or jury deliberates and reaches a verdict. In a jury trial, the jury decides the factual questions and the judge handles the legal ones. Civil jury verdicts do not always need to be unanimous, unlike in criminal cases. A trial might last a day or stretch across weeks depending on complexity.
Appeal and Collection
A verdict does not always end things. The losing side can appeal to a higher court, asking it to review whether the trial judge made legal errors that affected the outcome. An appeal is not a do-over. The appellate court does not hear new evidence or re-weigh witness credibility; it reviews the trial court’s legal rulings and procedures.8United States Courts. Appeals
If no appeal is filed, or the appeal fails, the final challenge is collecting. A judgment on paper does not automatically put money in anyone’s pocket. The winning party may need to take further legal steps to enforce it, like garnishing wages, placing liens on property, or seizing bank accounts. Collecting from a defendant without assets, or one determined not to pay, can be the most frustrating part of the entire process.
What Civil Litigation Costs
Litigation is expensive, and understanding the cost structure before you file is worth more than most of the legal advice you will get afterward. Upfront costs include filing fees, which vary by court and can range from a couple hundred dollars to several hundred, plus the cost of serving the complaint. From there, discovery is where expenses escalate. Depositions require court reporters, expert witnesses bill for their time, and document production in complex cases can cost tens of thousands of dollars.
Attorney fees are usually the biggest expense. Civil lawyers generally charge one of two ways. Hourly billing is standard for contract disputes, business litigation, and defense work. Contingency fee arrangements, where the lawyer takes a percentage of the recovery instead of billing hourly, are common in personal injury and employment cases. Contingency fees typically fall between 33 and 40 percent of the settlement or award. Under a contingency arrangement, you pay nothing upfront and owe nothing if you lose, but you give up a significant share of any recovery.
Some federal and state statutes include fee-shifting provisions, where the losing party pays the winner’s attorney fees. That is the exception. In most civil cases, each side pays its own legal costs regardless of who wins.
How Civil Cases Differ From Criminal Cases
Civil and criminal cases do fundamentally different work. A civil case exists to make an injured party whole, usually through money. A criminal case exists to punish conduct society has prohibited, with consequences that can include fines, probation, or imprisonment. The same event can trigger both. If someone assaults you, the government can prosecute them criminally and you can separately sue them for your medical bills and other losses.
The parties are different too. A civil case is one private party against another. A criminal case is brought by the government through a prosecutor, and the defendant has constitutional protections, including the right to a court-appointed attorney, that do not apply in civil litigation.
The most consequential difference is the burden of proof. In civil litigation, the plaintiff must prove the case by a preponderance of the evidence, meaning more likely true than not, essentially anything above a 50 percent probability.9Legal Information Institute. Preponderance of the Evidence Criminal cases require proof beyond a reasonable doubt, a much higher bar that demands the evidence leave the jury firmly convinced of guilt.10Legal Information Institute. Beyond a Reasonable Doubt That gap is why someone can be acquitted of criminal charges and still lose a civil lawsuit over the same conduct.
