What Happens During a Deposition: Rules, Objections, and Later Use

During a deposition, a court reporter places you under oath, attorneys from each side question you on the record for up to seven hours in a single day, and every word is transcribed into a sworn written record that carries the same legal weight as courtroom testimony.¹ Lying under that oath is federal perjury, punishable by a fine and up to five years in prison.² Depositions usually take place in a law office or conference room during the discovery phase of a lawsuit, long before any trial.

Who Is in the Room

The setting is small and the cast is predictable. You, the witness, sit at a conference table across from the attorney who noticed your deposition. Your own attorney, if you have one, sits beside you. A court reporter sits at one end with a stenographic machine, administers your oath, and transcribes everything said on the record. Without a court reporter or equivalent recording officer, the deposition cannot proceed as an official legal event.¹

Other attorneys for other parties in the case may also be there, each with the right to ask you questions when the first attorney finishes. The parties to the lawsuit, plaintiffs and defendants alike, have the right to attend in person even when they are not the ones being deposed.¹ If the parties have agreed to video, or a court has ordered it, a videographer runs a camera focused on you. The camera cannot distort your appearance or demeanor.

The Oath and the Ground Rules

The deposition opens with the court reporter going on the record and stating the date, time, location, your name, and everyone present.¹ You then swear or affirm to tell the truth. From that moment, your answers carry the same consequences as testimony given in a courtroom. A deliberately false statement of material fact is perjury under federal law.²

After the oath, the examining attorney walks you through a short set of ground rules. The wording varies, but the substance is nearly universal. Answer out loud rather than nodding or shaking your head, because the court reporter cannot transcribe a gesture. Wait for the full question before you start answering; overlapping speech produces an unreadable record. Ask for clarification whenever a question confuses you, rather than guessing at what the attorney meant. These instructions sound routine, but they are what keep the transcript clean enough for a judge to read months later.

How the Questioning Unfolds

The attorney who noticed the deposition goes first. Questioning typically starts with background: your name, job, education, and connection to the case. That warm-up locks basic biographical details into the record and gets you accustomed to the question-and-answer rhythm before the harder material arrives.

The scope then opens up. Under the federal rules, attorneys can ask about any nonprivileged matter relevant to a claim or defense, so long as the discovery request is proportional to the needs of the case.³ A question does not need to produce trial-admissible evidence on its own. Attorneys regularly ask about things that would draw an objection at trial, because depositions are meant to be wider-ranging than courtroom examination.

When the first attorney finishes, the others take their turns. Your own attorney often uses this time to clean up ambiguous answers or let you add context that got lost during adversarial questioning. In cases with multiple defendants or cross-claimants, several rounds of follow-up can stretch even a straightforward deposition into a full day.

Exhibits

Attorneys frequently introduce documents, photographs, emails, and other evidence while questioning you. The court reporter marks each item with a sequential exhibit number, your name, and the date. The attorney then hands you the exhibit and asks you to identify it and answer questions about it. A typical exchange: “I’m handing you what’s been marked as Exhibit 3. Do you recognize this email?” Your answers become part of the transcript, and the exhibit itself is attached to the record.

Objections and When You Can Refuse to Answer

There is no judge in the room. When an attorney objects during your deposition, the court reporter notes the objection on the record, and you answer the question anyway. A judge decides later, if the testimony is offered in court, whether the objection was valid.¹ This “object and answer” approach keeps the deposition moving.

Most objections go to the form of the question: that it is leading, vague, compound, or assumes facts not in evidence. By rule, objections must be concise, nonargumentative, and nonsuggestive.³ An attorney who uses wordy objections to coach a witness, so-called speaking objections, risks sanctions.

Your attorney can instruct you not to answer a question only in three narrow situations: to protect a legal privilege such as attorney-client communications, to enforce a limitation the court has already ordered, or to pause the deposition long enough to file a motion arguing that the questioning is abusive.¹ Outside those circumstances, refusing to answer is improper and can lead to sanctions under Rule 37.⁴

If the questioning crosses into harassment or bad faith, you or any party can move to terminate or limit the deposition. The motion can go to either the court where the case is pending or the court in the district where the deposition is happening, and if you demand it, the deposition pauses until the court rules.³ The losing side typically pays the other side’s expenses, so these motions are not filed lightly.

Breaks and Talking to Your Attorney

You can ask for reasonable breaks. Bathroom breaks, lunch, and a few minutes to collect yourself are normal and expected. The complication is whether you can confer with your attorney during those breaks.

The widely accepted rule is that your attorney cannot call a break to confer with you while a question is pending. You have to answer first. Beyond that, courts split on how freely attorneys and witnesses can talk during routine breaks. Some allow open consultation during lunch or between topics; others restrict break conversations to privilege issues only. Assume anything you discuss during a break could be asked about once questioning resumes.

How Long It Lasts

Federal rules set a default limit of one day of seven hours for a single deposition.¹ That clock counts only the time spent asking and answering questions. Breaks, lunch, and off-the-record discussions do not eat into it. The parties can agree to a shorter or longer session, and a court can extend the time when the case is complex or when someone’s behavior has delayed the examination.

In practice, most depositions of fact witnesses run two to four hours. Depositions of experts and of key parties in high-stakes litigation routinely fill the full seven hours. If the attorney runs out of time with ground still to cover, continuing on another day requires either the other side’s consent or a court order.

Remote Depositions

Federal rules allow depositions by telephone or videoconference when the parties agree or a court orders it.¹ They became far more common after 2020 and remain a standard option, especially for out-of-state witnesses. The deposition legally takes place wherever you are sitting when you answer, not where the questioning attorney happens to be.

Everything else works the same. The oath still goes on the record, the court reporter still transcribes everything, and the same objection rules apply. The practical differences are technical: the video platform has to be reliable, everyone needs a solid internet connection, and exhibits are usually shared electronically rather than handed across the table.

How to Prepare and Conduct Yourself

Preparation matters more than most witnesses realize. The single most important rule is simple: tell the truth. A few practical habits keep witnesses out of trouble.

Answer only what is asked. Listen to the actual question, give a direct answer, and stop talking. Volunteering extra information is the most common mistake, and it opens new avenues for the opposing attorney.⁵
Say “I don’t know” when it is true. You are not required to have an answer for every question, and guessing fills the record with inaccurate testimony that can be used against you.
Do not speculate. Avoid “I think,” “I believe,” or “I assume” unless the question asks for your opinion. Stick to facts you personally know.⁵
Review relevant documents beforehand. If the case involves a contract, incident report, or set of emails, re-read them before the deposition. Your memory will be tested against the paper trail.
Bring what the subpoena demands. If your subpoena required you to produce documents, bring everything listed. Failing to produce records can mean sanctions or a second deposition at your expense.

What Happens When the Questioning Ends

Once every attorney has finished, the court reporter prepares a verbatim transcript and certifies that you were properly sworn and that the record accurately reflects what was said.¹ If the session was recorded on video, that recording accompanies the transcript as part of the official record.

You have the right to review the transcript within 30 days of being notified it is available. During that window, you can identify errors and submit a signed statement, commonly called an errata sheet, listing each change and the reason for it.¹ The process was designed for genuine transcription mistakes: the reporter typed “yes” when you said “no,” or misspelled a technical term. A majority of federal appellate circuits take a dim view of witnesses who use the errata sheet to rewrite substantive answers. As one court put it, a deposition is not a take-home exam. A dramatic reversal does not erase the original answer; both versions go into the record, and the opposing side gets to ask the jury which one they believe.

How Your Deposition Testimony Gets Used Later

A deposition transcript does not just sit in a file. It becomes an active tool in the case.

Impeachment. If you testify at trial and say something different from what you said under oath at your deposition, the opposing attorney can read the conflicting deposition testimony to the jury. Nothing damages credibility faster than a witness’s own prior words contradicting their current story.⁶
Substitute for live testimony. When a witness has died, lives more than 100 miles from the courthouse, is too ill to attend, or cannot be reached by subpoena, their deposition can be read into the record at trial.⁶
Statements of an opposing party. The deposition of a party, or of someone who was a company’s officer, director, or managing agent at the time, can be used by the opposing side for any purpose at all, not just impeachment.⁶

Deposition testimony also drives pretrial motions. Attorneys routinely attach deposition excerpts to motions for summary judgment, arguing that the testimony proves or disproves a key element of the case without the need for a trial at all. A careless answer at a deposition can end a case months before a jury is seated, which is why experienced litigators treat the deposition with as much seriousness as the trial itself.
