What Is a Deposition?
Last updated: March 2026
A deposition is a formal question-and-answer session in a lawsuit where a witness or party gives sworn testimony before trial. Depositions are part of the discovery process and can play a major role in how a case is evaluated, prepared, and sometimes resolved.
What is a deposition in a lawsuit?
A deposition is an out-of-court proceeding where a person answers questions under oath. The testimony is usually taken in front of a court reporter, and sometimes a video recording is also made. Depositions are commonly used to gather facts, preserve testimony, evaluate witnesses, and better understand the strengths and weaknesses of a case.
Why depositions matter
Depositions matter because they can reveal important details about what happened, what a witness remembers, and how a party explains the facts. Testimony given during a deposition can affect settlement discussions, motion practice, trial strategy, and credibility issues later in the case.
Who can be deposed?
- Parties to the lawsuit
- Fact witnesses
- Corporate representatives
- Treating medical providers
- Experts and consultants in some cases
- Other individuals with relevant information
Who is usually present at a deposition?
A deposition usually includes the witness being questioned, the attorneys for the parties, and a court reporter. Sometimes a videographer is also present. Depending on the type of case, interpreters, corporate representatives, or other permitted individuals may attend as well.
What kinds of questions are asked?
The questions depend on the case. Lawyers may ask about background information, timelines, records, communications, injuries, medical treatment, product use, workplace conditions, exposure history, prior statements, and other facts relevant to the claims or defenses. Some questions are narrow and factual, while others test memory, detail, and consistency.
Is a deposition the same as testifying at trial?
Not exactly. A deposition happens before trial and usually takes place in an office or similar setting rather than a courtroom. But it is still sworn testimony, and answers can matter later. Deposition testimony may be used in motion practice, impeachment, or other parts of the case depending on the rules that apply.
Can lawyers object during a deposition?
Yes. Lawyers may object to certain questions, although the witness often still answers unless instructed otherwise under applicable rules. The exact handling of objections can vary by jurisdiction and the nature of the issue being raised.
How long can a deposition take?
Some depositions are relatively short, while others can last much longer. Timing depends on the complexity of the case, the amount of information involved, the role of the witness, and the rules or agreements that govern the deposition. In larger cases, depositions may take place over multiple sessions.
How depositions affect settlement and trial
Depositions often change how parties evaluate risk. A strong or weak witness performance, important admissions, inconsistencies, or newly clarified facts can all influence whether a case settles or continues toward trial. In that sense, depositions can become one of the most important moments in discovery.
