Civil cases take so long because they move through a fixed sequence of phases, and each phase carries its own deadlines, waiting periods, and chances for delay that pile onto the ones before it. A federal lawsuit that actually reaches a verdict typically takes about two years from the day it is filed, and complex matters or cases that go up on appeal can stretch to four or five. The biggest drivers are discovery, motion practice, overloaded court calendars, and the settlement process itself.
No single step is to blame. The system is built to be thorough, and thoroughness compounds.
Every Phase Has to Finish Before the Next One Starts
A lawsuit begins when the plaintiff files a complaint and the court issues a summons. The plaintiff then has to physically deliver both to the defendant, a step called service.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Finding a defendant who is dodging service or lives out of state can burn weeks on its own.
Once served, the defendant has a limited window to respond. In federal court the standard deadline is 21 days after service, or 60 days if the defendant waives formal service.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons State deadlines usually fall in the 20-to-30-day range. Instead of answering, the defendant might file a motion to dismiss. If the court grants that motion with permission to fix the problem, the plaintiff refiles an amended complaint and the response clock starts again. Counterclaims and additional parties each trigger their own deadlines. The initial exchange alone can run three to six months.
After the pleadings settle, the parties hold a planning conference and the judge issues a scheduling order laying out when discovery closes, when expert reports are due, and when motions must be filed.2Legal Information Institute. Federal Rules of Civil Procedure Rule 16 – Pretrial Conferences; Scheduling; Management That order becomes the backbone of the case. Move one deadline and the rest usually have to move too, so an early delay ripples through everything after it.
Discovery Is the Longest Phase
Discovery is where each side gathers evidence from the other, and it is almost always what makes a case feel endless. In complex commercial disputes or class actions, discovery alone can run beyond a year. Three tools drive the timeline.
Written Questions
Interrogatories are written questions answered under oath. Federal rules cap them at 25 per side unless the court allows more.3Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties That number sounds manageable, but each question tends to have subparts, and the answers often require weeks of internal research.
Document Requests
Document requests are where cases really bog down. Either side can demand any relevant documents, electronically stored information, or physical items the other side has. The responding party has 30 days to produce the materials or object.4Legal Information Institute. Federal Rules of Civil Procedure Rule 34 – Producing Documents, Electronically Stored Information, and Tangible Things In practice, 30 days is a starting point. When a company has to search years of emails, shared drives, and backup tapes, collection and review takes months. Disputes over privilege or scope add more delay and often require the judge to step in.
Depositions and Experts
Depositions are live, sworn testimony recorded by a court reporter. Federal rules limit each side to 10 depositions and cap each one at seven hours in a single day.5Legal Information Institute. Federal Rules of Civil Procedure Rule 30 – Depositions by Oral Examination Coordinating schedules among several attorneys, witnesses, and a court reporter across different cities creates weeks of dead time between sessions.
Expert witnesses add another bottleneck. Expert reports are due at least 90 days before trial, and rebuttal experts get an additional 30 days after the other side’s disclosure.6Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery After the reports are exchanged, each expert usually sits for a deposition. Qualified experts are in demand, so their calendars often set the pace.
When One Side Stalls
Not every delay is structural. Sometimes one side stonewalls and the other has to file a motion to compel. If the court grants it, the losing side usually pays the winner’s legal fees for having to bring the motion.7Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions For serious violations, courts can strike pleadings, block evidence, or enter a default judgment. Getting there takes time: the offending party gets chances to comply, the court holds hearings, and months can pass before anything is actually enforced.
Motions Pause the Case While the Judge Reads
Throughout the case, either side can ask the judge to decide specific issues. The most time-consuming is a motion for summary judgment, where one party argues the facts are so one-sided that no trial is needed. The court should grant it when there is no genuine dispute about the material facts and the moving party is entitled to win as a matter of law.8Legal Information Institute. Federal Rules of Civil Procedure Rule 56 – Summary Judgment
The process is slow by design. The moving party files a brief with supporting evidence. The other side files an opposition, often with its own evidence. The first party files a reply. Each step has a deadline, and extensions are common. Then the judge has to read everything and issue a decision, which can take a few weeks or more than six months depending on the judge’s caseload. The trial date often slides to give the judge time to decide whether a trial is even necessary.
Summary judgment is not the only culprit. Motions to exclude evidence, motions to certify a class, and motions about which law applies all follow the same brief-response-reply-wait cycle. A complex case can carry a dozen significant motions, each adding weeks or months.
The Court’s Own Calendar Adds Delay
Even when both sides move efficiently, the court’s calendar does not. Federal district courts had roughly 398,000 pending civil cases as of 2025.9United States Courts. Federal Judicial Caseload Statistics 2025 State courts handle far more. Each judge is juggling hundreds of cases at once, and there are only so many courtroom hours in a week.
Criminal cases make it worse for civil litigants. Criminal defendants have a constitutional right to a speedy trial, and federal law requires criminal trials to begin within 70 days of indictment. Criminal matters jump to the front of the line whenever the calendar gets crowded, and civil trials routinely get bumped to make room, sometimes repeatedly. A civil trial date set 18 months in advance may be pushed back two or three times before a courtroom actually opens up.
Continuances compound the problem. Either party can ask the judge to postpone a hearing or trial for legitimate reasons: a witness is unavailable, new evidence surfaces, an attorney has a scheduling conflict. Each granted continuance shifts not just that event but everything that depends on it.
Settlement and Mediation Take Time Even When They Work
About 95% of civil cases settle before trial. That is the good news. The less obvious part is that getting to a settlement usually adds months rather than shortens the case.
Serious settlement talks rarely happen until discovery is well underway. Both sides need enough information to value the case, which means waiting on documents and depositions. Offers and counteroffers then move slowly, especially when insurance adjusters or corporate decision-makers have to approve each step.
Many courts require mediation before setting a trial date. Scheduling a session that works for all the attorneys, their clients, and a neutral mediator takes time, and the sessions themselves can last from a few hours to several days. Even mediations that do not produce an immediate deal often lead to a settlement weeks later. All of that is time on the clock.
Appeals Can Add Another Year
A verdict does not necessarily end the case. The losing party has 30 days after judgment to file a notice of appeal, or 60 days if the government is a party.10Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right; When Taken Once filed, the appeal moves on the appellate court’s schedule, which the parties cannot speed up.
The appeal involves ordering the trial transcript, assembling the record, writing lengthy briefs, and sometimes oral argument. The median time from notice of appeal to final decision in federal civil cases is about 11.5 months.11United States Courts. Table B-4A – U.S. Courts of Appeals Median Time Intervals for Civil and Criminal Appeals Busy circuits and complex appeals run longer. If the appellate court sends the case back for a new trial or further proceedings, parts of the trial-level process start over.
What Pushes a Case Toward the Long End
Some cases close in under a year; others run for half a decade. The factors that stretch a case out are usually some combination of these: multiple parties and overlapping claims, large volumes of electronic documents to review, reliance on expert witnesses whose calendars drive scheduling, contested motions that require the judge to issue a written ruling, a crowded docket where criminal trials keep bumping the civil calendar, and an appeal at the end. A case that avoids most of those can finish quickly. A case that hits all of them is why “years” is the honest answer when someone asks how long their lawsuit will take.
