A civil lawsuit is a court case in which one private party — a person, business, or organization — sues another to enforce a legal right or recover for a loss, with the outcome usually being money or a court order rather than jail. Civil lawsuit cases cover almost every dispute that isn’t a crime: car accidents, unpaid contracts, evictions, divorces, discrimination claims, defamation, product defects, will contests, and much more. They make up the vast majority of cases filed in American courts each year, and they follow a broadly similar path whether the fight is over $2,000 or $2 billion.
How Civil Cases Differ From Criminal Cases
The core difference is who sues and what’s at risk. In a criminal case, the government charges a defendant and a conviction can mean prison, probation, or a fine paid to the state. In a civil case, one party sues another (or a government agency sues in a regulatory role), and the losing side pays money, is ordered to do or stop doing something, or both. No one goes to jail for losing a civil case.
The proof required is also lower. A criminal prosecutor must prove guilt “beyond a reasonable doubt.” A civil plaintiff usually needs only a “preponderance of the evidence” — more likely than not, essentially better than a 50 percent chance.
A middle standard, “clear and convincing evidence,” applies to certain civil matters where more than money is on the line. The Supreme Court has described it as requiring an “abiding conviction” that a claim is “highly probable.” Courts typically demand it for fraud claims, restraining orders, will contests, dependency proceedings that could terminate parental rights, and conservatorships.
Common Types of Civil Lawsuits
Civil law is a wide field, but most cases fall into a handful of categories:
- Torts — personal injury and property damage from car accidents, medical malpractice, defamation, fraud, negligence, and defective products.
- Breach of contract — one side didn’t do what it promised, didn’t pay, or didn’t deliver.
- Family law — divorce, custody, child support, guardianship, adoption, domestic violence.
- Landlord and tenant — evictions, security deposits, habitability complaints.
- Employment and administrative — wage disputes, workers’ compensation, unemployment hearings.
- Civil rights — discrimination and constitutional-rights claims, often under federal statutes.
- Consumer issues — debt collection, bankruptcy, fraud.
- Equitable claims — asking the court to order someone to do or stop doing a specific thing.
- Probate — disputes over wills, estates, trusts, and guardianships.
These categories overlap in real life. A car crash can generate a tort claim against the other driver and a contract claim against an insurer. The same underlying facts can be handled in state or federal court depending on the circumstances.
Where Civil Cases Are Filed: State or Federal Court
Most civil lawsuits are filed in state court. States handle the bulk of contract, personal injury, family, landlord-tenant, and probate cases. Each state organizes its courts a little differently, but a tiered structure is typical.
At the bottom sit small claims courts, with simplified procedures and low dollar limits. Massachusetts caps small claims at $7,000; California’s limit is $10,000. Lawyers are often not allowed, and there is no jury. Above small claims, district or circuit courts handle larger matters. In New Hampshire, the circuit court’s district division covers claims under $10,000, and the superior court has exclusive jurisdiction over claims above $25,000. Family, probate, and other specialized divisions round out the system.
Federal courts hear civil cases only when a specific gateway opens. The two main ones are federal question jurisdiction and diversity jurisdiction. Federal question jurisdiction covers cases “arising under” the U.S. Constitution, a federal statute, or a federal regulation. The federal issue has to appear in the plaintiff’s own complaint; an anticipated defense isn’t enough, a rule known as the well-pleaded complaint rule.
Diversity jurisdiction applies when every plaintiff is a citizen of a different state from every defendant and the amount in controversy is more than $75,000. Congress has raised that threshold over time — from $3,000 in the original statute to $10,000 in 1958, $50,000 in 1988, and $75,000 in 1996. For class actions, the Class Action Fairness Act of 2005 set a separate $5,000,000 threshold. When a case that qualifies for federal court is filed in state court, the defendant can often “remove” it to federal court.
How a Civil Lawsuit Moves Through Court
A civil case moves through a sequence of stages, though few ever reach the end of that sequence.
Before Filing and the Pleadings
Many disputes begin with a demand letter or an attempt at mediation. If informal resolution fails, the plaintiff files a complaint with the court, pays the filing fee, and has the defendant formally served. The federal district court filing fee is $350 under 28 U.S.C. § 1914(a); state fees vary widely. The complaint has to describe the harm, explain how the defendant caused it, establish the court’s jurisdiction, and state what relief the plaintiff wants.
The defendant then files an answer, which may include counterclaims, or files a motion to dismiss arguing that the complaint has a fatal defect — the court lacks jurisdiction, for example, or the plaintiff hasn’t stated a valid legal claim.
Discovery
Once the case survives the pleading stage, both sides exchange evidence in a phase called discovery. The point is to keep either side from being ambushed at trial. Discovery is usually the longest and most expensive part of a lawsuit. The main tools:
- Interrogatories: written questions the other side must answer under oath. Federal court limits each side to 25 unless the court allows more.
- Requests for production: demands for documents, emails, contracts, financial records, or physical evidence.
- Depositions: in-person questioning under oath, recorded by a court reporter.
- Requests for admissions: statements the other side must admit or deny. Anything admitted is treated as established.
Fights over the scope of discovery are common. A party can ask for a protective order to limit requests it considers invasive or overbroad.
Summary Judgment
After discovery, either side can ask the court to decide the case (or particular claims) without a trial by moving for summary judgment. Under Federal Rule of Civil Procedure 56, the court must grant the motion when there is “no genuine dispute as to any material fact” and the moving party is entitled to judgment as a matter of law. The court views the evidence in the light most favorable to the party opposing the motion and asks whether a reasonable jury could find for that party.
The Supreme Court’s 1986 decision in Celotex Corp. v. Catrett made clear that summary judgment must be granted against a party who fails to produce enough evidence on an essential element of the case. By 2000, federal courts were disposing of roughly three times as many cases through summary judgment as through trial.
Trial
If the case doesn’t settle and doesn’t get thrown out on motion, it goes to trial. Either side in a civil case can request a jury under the Constitution; if both sides waive that right, a judge decides the case in a bench trial. In a jury trial, the lawyers pick jurors through voir dire, give opening statements, examine and cross-examine witnesses, and deliver closing arguments. The judge runs the proceeding, rules on evidence, and instructs the jury on the law. The jury then deliberates and returns a verdict on liability and damages.
Default Judgment
Not every case gets a defense. When a defendant fails to answer the complaint, the plaintiff can seek a default judgment. Under Federal Rule 55, the clerk first enters a formal notation of default, and then the plaintiff moves for judgment. If the claim is for a fixed dollar amount, the clerk can enter judgment directly; in more complicated cases, a judge decides the damages, sometimes after a hearing. A 2024 Federal Judicial Center study found practices vary across districts, with 36 districts letting clerks handle routine default judgments and 34 districts routing all default motions to a judge.
Appeals
A party unhappy with the outcome can appeal. An appeal is not a retrial. The appellate court reviews the trial record for legal error rather than reweighing the evidence. The standard of review depends on what’s being challenged. Pure legal questions get “de novo” review, with no deference to the trial court. Factual findings by a judge in a bench trial are reviewed under the “clearly erroneous” standard, meaning they stand unless the appellate court has a “definite and firm conviction that a mistake has been committed.” Procedural and discretionary rulings are reviewed for “abuse of discretion,” which is highly deferential. In rare cases a party can ask the full appellate court to rehear a case en banc, or petition the U.S. Supreme Court for a writ of certiorari, which the Supreme Court is not required to grant.
Why Most Civil Cases Never Reach Trial
The full lifecycle above describes a road that very few cases finish. In 1938, about 20 percent of federal civil cases went to trial. By 1962, that had dropped to 12 percent. Today only about 1 percent of federal civil cases are resolved at trial, and the jury trial rate sits around 0.7 percent. State courts show the same pattern. Civil jury trials as a share of all dispositions fell from about 1.8 percent in 1976 to 0.6 percent by 2002 in a National Center for State Courts study covering 22 states. In Texas, only 0.4 percent of civil cases reached a jury verdict in the fiscal year ending August 2009.
Several forces push cases off the trial track. Wider use of summary judgment, especially after the Supreme Court’s 1986 decisions, lets courts resolve cases before trial when the evidence clearly favors one side. Discovery costs, particularly for emails and other electronic evidence, push parties to settle. Courts actively encourage mediation. And stricter pleading standards from the Supreme Court’s decisions in Twombly (2007) and Iqbal (2009) give judges more room to dismiss weak cases early.
Alternative Dispute Resolution
Because trials are rare and litigation is expensive, most civil disputes end through some form of alternative dispute resolution. The two most common are mediation and arbitration.
In mediation, a neutral third party helps the sides negotiate a resolution. The mediator can’t impose an outcome; any agreement has to be voluntary, and if the parties reach one, it is written up as an enforceable contract. Courts often order parties to attempt mediation before trial, though no one is forced to actually settle. The U.S. Alternative Dispute Resolution Act of 1998 requires every federal district court to run an ADR program.
Arbitration is more formal. A neutral arbitrator or panel hears evidence and arguments and issues a decision called an award. Binding arbitration is final and enforceable in court, with only narrow grounds for appeal. Many commercial and employment contracts require binding arbitration, so the parties have agreed in advance to skip court entirely. Non-binding arbitration produces an advisory opinion the parties can accept or reject. Other court-connected options include early neutral evaluation, where an expert assesses each side’s strengths and weaknesses, and summary jury trials, where lawyers present abbreviated arguments to a mock jury whose advisory verdict helps the parties gauge likely outcomes.
What Filing and Fighting a Civil Case Costs
Costs depend heavily on complexity, but even a straightforward case has real expenses. Federal court filing fees start at $350. State court filing fees range from under $50 for small claims in some jurisdictions to $1,500 or more for complex matters. Beyond the filing fee, the main costs are attorney fees, discovery, and expert witnesses.
Lawyers typically charge in one of three ways. Hourly rates range from around $200 to over $500 per hour depending on experience and location. In personal injury and other plaintiff-side cases, contingency fees are common: the lawyer takes a percentage of the recovery, usually one-third to 40 percent, and the client pays nothing up front. If the case loses, the client owes no attorney’s fee. Flat fees show up for predictable work like bankruptcy filings.
Discovery is often the biggest line item. A single deposition can cost $500 to $3,000 once court reporter and transcript fees are included, and expert witnesses charge $300 to more than $1,000 per hour.
Under the “American Rule,” each side pays its own attorney fees regardless of who wins. That has been the U.S. default since the Supreme Court adopted it in Arcambel v. Wiseman (1796), and it contrasts with the English “loser pays” system. There are roughly 200 statutory exceptions, mostly in civil rights, environmental, and consumer protection laws, where Congress has authorized fee-shifting to encourage private enforcement. The Equal Access to Justice Act, for example, allows fee awards against the federal government when its position was not “substantially justified.” Courts also have inherent power to award fees when a party litigates in bad faith, which the Supreme Court confirmed in Chambers v. NASCO, Inc. (1991).
Deadlines for Filing: Statutes of Limitations
Every civil claim has a filing deadline called a statute of limitations. Miss it and the case is barred no matter how strong it is. Deadlines vary by state and by claim type. Personal injury deadlines range from one year in states like Kentucky and Tennessee to six years in Maine and North Dakota. Written contract claims can be filed within three years in Alaska and Delaware but have a ten-year window in Illinois, Iowa, and several others. Property damage deadlines run from two years in Alabama and Arizona to ten years in Rhode Island.
These clocks can be paused, or “tolled,” in certain situations — when the injured party is a minor, when they are mentally incapacitated, or when the harm hasn’t yet been discovered. Claims against government entities often have shorter windows and may require filing an administrative claim before a lawsuit can be brought.
Class Actions
When many people share the same claim against the same defendant, a class action lets one or a few named plaintiffs sue on behalf of the entire group. Federal class actions are governed by Rule 23 of the Federal Rules of Civil Procedure, which imposes four threshold requirements. The class must be too large for individual suits (numerosity). There must be legal or factual questions common to the group (commonality). The named plaintiffs’ claims must be typical of the class (typicality). And the representatives must adequately protect the class’s interests (adequacy).
Beyond those prerequisites, the case has to fit one of three categories. The most common for money-damages cases is Rule 23(b)(3), which requires that common questions predominate over individual ones and that a class action is the best way to handle the dispute. In 23(b)(3) cases, the court must give class members the best practicable notice and an opportunity to opt out; anyone who doesn’t opt out is bound by the outcome. Class actions seeking injunctive or declaratory relief usually proceed under Rule 23(b)(2), where opt-out rights aren’t automatic.
The court certifies the class at an early stage, and the plaintiffs must prove all requirements by a preponderance of the evidence. The court also appoints class counsel, weighing experience, knowledge of the law, and resources. Any settlement needs court approval after a hearing to confirm that the terms are “fair, reasonable, and adequate.”
What a Winning Plaintiff Can Recover
When a plaintiff wins, the court can order several types of relief. The most common is compensatory damages: money to make the plaintiff whole for actual losses, including medical bills, lost income, property repair costs, and pain and suffering. In cases involving especially egregious conduct, a jury may add punitive damages, which are meant to punish the defendant and deter similar behavior.
Not all remedies are monetary. Courts can issue injunctions ordering a party to do something (perform a contract, clean up a pollution site) or to stop doing something (cease infringing a patent, stay away from a person). A declaratory judgment fixes the parties’ legal rights without ordering damages or action, which is useful when the fight is over what a contract means or whether a law applies. In family law, remedies more often take the form of custody arrangements, support orders, or property division than damages.
