A civil case is a lawsuit between two parties in which the person bringing the claim asks a court for money or a specific order, not for the other side to be jailed. The person who files is the plaintiff, the person being sued is the defendant, and either side can be an individual, a business, or a government agency. Civil cases cover car accidents, broken contracts, divorces, employment disputes, property fights, and much more. They move through a defined process: filing, response, discovery, possible settlement, and sometimes trial.
How a Civil Case Differs From a Criminal One
The clearest difference is who sues and what the loser faces. In a criminal case, the government prosecutes a defendant for breaking the law, and a conviction can lead to prison. In a civil case, a private party sues another private party, and the losing side pays money or is ordered to do (or stop doing) something. Civil judgments do not send anyone to jail.
The proof standard is also lower. Criminal prosecutors must prove guilt beyond a reasonable doubt. Civil plaintiffs usually only have to show that their version is more likely true than not, a standard called preponderance of the evidence, which courts sometimes describe as a greater than 50% likelihood.1Legal Information Institute. Wex – Preponderance of the Evidence
One wrinkle worth knowing: the same incident can produce both a criminal prosecution and a civil lawsuit. An assault victim, for instance, can sue for medical bills whether or not the state secures a conviction, because the two cases use different proof standards and seek different outcomes.
Types of Disputes That Fall Under Civil Law
Civil law is broad. The main categories include:
- Tort claims, which arise when someone’s conduct causes harm. Negligence cases like car crashes and slip-and-falls are the most common, but torts also cover intentional wrongs such as defamation, fraud, and assault.
- Contract disputes, where one party fails to deliver on a legally binding agreement. These range from unpaid invoices to failed business deals.
- Property disputes, including boundary lines, easements, title questions, and landlord-tenant conflicts.
- Family law matters, such as divorce, custody, child support, and spousal support.
- Employment disputes, including wrongful termination, discrimination, and wage claims.
- Class actions, in which one or more plaintiffs sue on behalf of a large group that suffered the same harm. Federal rules require the group to be large enough that individual suits would be impractical and the claims to share common legal questions.2Legal Information Institute.

Which Court Hears the Case
Most civil cases are filed in state court. Federal courts step in under two main scenarios. The first is federal question jurisdiction, which covers claims arising under the Constitution, a federal statute, or a treaty.3Office of the Law Revision Counsel. 28 US Code 1331 – Federal Question The second is diversity jurisdiction, which applies when the plaintiff and defendant are from different states and the amount in dispute is more than $75,000.4Office of the Law Revision Counsel. 28 US Code 1332 – Diversity of Citizenship; Amount in Controversy
For smaller disputes, states run small claims courts with simplified procedure, lower filing fees, and relaxed rules of evidence. Dollar caps vary widely, ranging from $2,500 to $25,000 depending on the state. People often appear without an attorney, which is the entire point of the streamlined format.
How a Civil Case Starts
A civil case formally begins when the plaintiff files a complaint with the court.5United States Courts. Civil Cases The complaint says what happened, how the defendant caused the harm, what relief the plaintiff wants, and why this particular court has authority to decide the matter. Federal plaintiffs pay a filing fee when the complaint is submitted, and those who cannot afford it can apply to proceed without payment.
Serving the Defendant
Filing does not notify the defendant. The plaintiff must have the defendant personally served with a copy of the complaint and a summons telling them they have been sued and setting a response deadline.6Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons This step, called service of process, is a constitutional requirement; a court cannot act against a defendant who has not been properly notified.7Legal Information Institute. Wex – Service of Process A professional process server or, in some places, a sheriff’s deputy handles it.
The Answer
After being served, a defendant typically has 21 days to file a written answer.8Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections; When and How Presented The answer responds to each allegation in the complaint by admitting it, denying it, or stating that the defendant lacks enough information. Defendants can also raise defenses and file counterclaims of their own.
Ignoring the lawsuit is a mistake. If a defendant never responds, the plaintiff can ask the court for a default judgment. When damages can be calculated from the paperwork, the clerk enters the judgment directly; in less straightforward situations, the court holds a hearing to set the amount.9Legal Information Institute. Federal Rules of Civil Procedure Rule 55 – Default; Default Judgment
Discovery
Once initial pleadings are in, the case enters discovery, a formal period in which both sides exchange information. Discovery is meant to prevent surprises at trial and give each side a clear read on the evidence before deciding whether to settle. It is often the longest and most expensive phase of a civil case, sometimes stretching across months or years.
Attorneys use three main tools:
- Interrogatories, written questions the other side answers under oath. Federal parties are limited to 25 unless the court allows more.10Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties
- Requests for production, formal demands for documents, electronic files, photos, or other tangible evidence. The receiving party has 30 days to comply or object.11Legal Information Institute. Federal Rules of Civil Procedure Rule 34 – Producing Documents, Electronically Stored Information, and Tangible Things
- Depositions, live questioning of a party or witness under oath outside the courtroom, recorded by a stenographer or on video, and usable at trial.12Legal Information Institute. Federal Rules of Civil Procedure Rule 30 – Depositions by Oral Examination
When a case depends on technical or specialized knowledge, either side can hire expert witnesses. Experts the parties plan to call at trial must be disclosed in advance, along with a written report. Failing to disclose an expert properly can lead the court to exclude the witness.
How Most Cases End Before Trial
Most civil cases never reach a jury. Settlement, pretrial motions, and alternative dispute resolution usually resolve things first.
Summary Judgment
After discovery, either side can move for summary judgment, asking the court to decide the case without a trial. The judge grants the motion only when the evidence shows no genuine dispute over the key facts and the law clearly favors one side.13Legal Information Institute. Federal Rules of Civil Procedure Rule 56 – Summary Judgment When granted, it ends the case.
Settlement
The parties can negotiate a settlement at any point. Settling puts the outcome in the parties’ hands, removes jury unpredictability, and stops the ongoing cost of litigation. Because settlement agreements are private contracts, they can include payment schedules, confidentiality terms, and other provisions a court would not normally order. Most civil cases settle.
Mediation and Arbitration
Many courts require or encourage alternative dispute resolution before trial. In mediation, a neutral third party helps both sides negotiate toward a voluntary agreement; the mediator cannot impose a result, and if the parties cannot agree, the case returns to the normal track. Arbitration is closer to a private trial: an arbitrator hears evidence and issues a binding decision that is usually final and very hard to appeal. Many commercial contracts contain mandatory arbitration clauses, committing the parties to skip court altogether if a dispute arises.
Trial and What the Court Can Award
If a case does go to trial, both sides present evidence and testimony to a judge (bench trial) or a jury. The plaintiff carries the burden of proof and goes first. The defendant then presents its evidence. After both sides rest, the judge or jury deliberates and issues a judgment.
Money Damages
The most common remedy is a financial award. Compensatory damages reimburse the plaintiff for actual losses: medical bills, lost income, property damage, and similar out-of-pocket costs. In cases involving especially reckless or malicious conduct, courts can also award punitive damages intended to punish the defendant and deter similar behavior. Punitive damages are rare and usually require conduct that goes well beyond ordinary negligence.
Equitable Relief
When money alone will not fix the problem, courts can order equitable relief. The two most common forms are injunctions and specific performance.14Legal Information Institute. Wex – Equitable Relief An injunction is a court order requiring someone to do something or stop doing something, which matters when the harm is ongoing, such as a business dumping waste near a property or a former employee violating a non-compete agreement.15Legal Information Institute. Wex – Injunctive Relief Specific performance forces a party to carry out the terms of a contract, and courts order it when the subject matter is unique enough that money is not a real substitute, such as the sale of a particular piece of real estate.
Appeals
Losing a case is not necessarily the end. Federal appellate courts can review final decisions from district courts.16GovInfo. 28 US Code 1291 – Final Decisions of District Courts The losing side must file a notice of appeal within 30 days of the judgment, and missing that deadline ends the right to appeal regardless of the arguments.17United States Court of Appeals for the Second Circuit. FRAP 4 – Appeal As of Right; When Taken
An appeal is not a second trial. The appellate court does not hear new evidence or new witnesses. It reviews the trial record for legal errors, such as whether the judge applied the wrong standard, improperly admitted or excluded evidence, gave incorrect jury instructions, or abused discretion in a way that affected the outcome. The court can affirm, reverse, or send the case back for further proceedings. Disagreement with the result is not enough; there has to be an identifiable error.
Collecting a Judgment
Winning and getting paid are different things. A judgment is a piece of paper. If the losing party does not pay voluntarily, the winner (now the judgment creditor) has to use legal collection tools.
Wage garnishment is the most common. Federal law caps garnishment for most debts at 25% of disposable earnings, or the amount by which weekly earnings exceed 30 times the federal minimum wage, whichever produces the smaller garnishment.18Office of the Law Revision Counsel. 15 US Code 1673 – Restriction on Garnishment Other tools include liens on real estate, bank account levies, and seizure of non-exempt personal property. Each requires additional court filings and comes with its own exemptions. If the defendant has no meaningful assets or income, collection can be difficult or impossible, which is why experienced attorneys evaluate a defendant’s ability to pay before investing heavily in litigation.
Deadlines to Sue
Every civil claim has a filing deadline called a statute of limitations. Once that period runs, the right to sue disappears regardless of how strong the case is. Deadlines vary by claim type and jurisdiction. Personal injury deadlines commonly range from one to six years. Written contract disputes often fall between four and six years. Federal statutory claims default to four years unless the specific law sets a different period.19Office of the Law Revision Counsel. 28 US Code 1658 – Time Limitations on the Commencement of Civil Actions
Certain circumstances can pause the clock, a concept known as tolling. The most common tolling situations involve plaintiffs who are minors, are mentally incapacitated, or did not know about the injury. In medical malpractice, for example, many jurisdictions start the clock from the date the patient discovered or reasonably should have discovered the injury rather than from the treatment date. The rules are strict and courts interpret them narrowly, so tolling is not a reliable safety net.
What It Costs
Civil litigation is expensive, and the costs reach well beyond attorney fees. Process servers, deposition transcripts, expert witnesses, and court reporters all add up. In complex cases, discovery alone can cost tens of thousands of dollars in document review and electronic data processing.
The default rule in the United States is that each side pays its own attorney fees, win or lose. That contrasts with the loser-pays approach used in many other countries. Exceptions exist: certain federal and state statutes allow a winning party to recover fees, and many contracts include fee-shifting provisions. Without one of those, legal fees are yours regardless of outcome.
Fee structures depend on the case. Personal injury lawyers commonly work on contingency, taking a percentage of what the plaintiff recovers (typically 30% to 40%) and charging nothing if the case loses. Contract, property, and business litigation more often run on hourly billing. Nailing down the fee arrangement before signing an engagement letter matters, because it affects whether pursuing the case makes financial sense in the first place.
