Taking Testimony Before Trial
A deposition puts a witness under oath months before trial, with no judge in the room and a court reporter taking every word. The transcript that results can be read at trial, used to contradict a change of story, or become the evidence itself if the witness never appears.

The rule in short
A deposition is oral testimony taken under oath before trial, on written notice to every other party, and recorded by an officer authorized to administer oaths. Federal Rule of Civil Procedure 30 limits a deposition to one day of seven hours and limits each side to ten depositions without leave of court. Objections are usually stated for the record and the answer is given anyway, with the judge ruling later if the passage is offered in evidence.
A deposition is sworn testimony taken before trial. The witness answers questions out loud, under oath, while a court reporter records everything, and the transcript that results can be used at trial. No judge is present and nobody rules on objections in the room.
It exists for three reasons. It finds out what a witness will say before the day it matters. It fixes that account in a form that can be used to contradict a different version later. And it preserves testimony from someone who may not be available at trial, through illness, distance or unwillingness.
Setting one up
Federal Rule of Civil Procedure 30 requires reasonable written notice to every other party, stating the time and place and, if known, the name and address of the person to be examined. State rules follow the same pattern, and several specify a minimum number of days rather than leaving reasonableness at large.
How the witness is compelled depends on who they are. A party to the case is bound by the notice alone and must attend. A witness who is not a party must be served with a subpoena, with the attendance fee and mileage tendered where the rules require it, following the mechanics in making a witness or a document appear.
Numbers are capped. Each side may take ten depositions before needing the court's permission, and a single deposition is limited to one day of seven hours unless the parties agree or the court allows more. Additional time is granted where a witness or another person impedes the examination, or where the material genuinely needs it.
Who is in the room
The officer taking the deposition administers the oath and makes the record. In practice this is a certified court reporter, sometimes joined by a videographer where the testimony will be played rather than read. The officer is neutral and does not participate in the questioning.
Everyone else is a participant. The questioning party asks first, then any other party may ask, and the party who produced the witness may ask follow-up questions. The witness may have a lawyer present even if they are not a party; that lawyer may object but generally may not answer for them.
Interpreters attend where the witness needs one, and are sworn as well. In a deposition, unlike a court hearing, the cost of the interpreter usually falls on the party who noticed the deposition rather than on the court.
Location follows the witness rather than the case. A deposition is normally taken where the deponent lives or works, which is why a case filed in one state can involve a day of testimony in another. Remote depositions by video are now common and are permitted by stipulation or by court order in most systems, with the officer and the witness in different places.
Preparation is the part a self-represented party most often skips. Bring the documents to be shown, in order, with copies for everyone present, and a short written outline of the points that have to be covered. Seven hours sounds generous and disappears quickly once exhibits are being marked one at a time.
In most systems an objection is stated concisely for the record and the witness answers anyway, leaving the judge to rule if the passage is later offered in evidence. The exceptions are narrow: a privilege, a limit the court already imposed, or a motion to suspend an abusive examination. Instructing a witness not to answer for any other reason invites a motion and a cost order.
What the transcript can do
| Use at trial | Condition | Who may offer it | Practical effect |
|---|---|---|---|
| Contradicting a witness | The witness testifies differently | Any party | Read to the jury alongside the new answer |
| Anything said by a party | The deponent is an opposing party | The other side | Admissible for any purpose in most systems |
| Substituting for live testimony | The witness is unavailable as the rules define it | Any party | The transcript is read or the video played |
| Supporting a pretrial motion | Sworn testimony is required | The moving or opposing party | Attached as an exhibit with the reporter's certificate |
Reviewing and correcting
After the transcript is prepared, the witness normally has a period to read it and note changes. The changes do not erase the original answer. Both versions stay in the record, and a substantive change invites questions at trial about why the answer moved, which is often worse than the original answer was.
The officer certifies the transcript and delivers it to the party who ordered it. Other parties buy copies at the copy rate. Federal reporter rates are published by the courts, and the categories run from ordinary thirty-day delivery through to same-day and hourly service, with each step costing more.
Ordering ordinary delivery is almost always the right call. Expedited rates exist for trials that are days away, not for a deposition taken months before one, and the difference on a long transcript is substantial. Where a video was made as well, the video house bills separately from the reporter, and a synchronized version costs more again.
Costs mount quickly: reporter attendance for the day, the transcript itself, exhibits, video where used, and the room. Some of it is recoverable at the end, because transcripts necessarily obtained for use in the case appear on the federal list of taxable costs, and the ordering mechanics are covered in getting a transcript and what it costs.
Whether to take one at all
Depositions are the most expensive discovery tool and the most revealing. They earn their price where credibility decides the case, where a document needs to be explained by its author, or where a witness may vanish before trial.
They are poor value for straightforward factual questions that a party could simply be asked in writing, for confirming dates and amounts, or in a small case where the transcript will cost more than the dispute is worth. A deposition taken because it seems like the expected next step, rather than because a specific question needs answering out loud, is money spent on a document nobody reads. Those jobs belong to the cheaper instruments described in written questions instead of a deposition.
Budget before scheduling. A day of testimony that cannot be paid for is worse than no testimony at all, and the wider picture of what a case costs to run is set out in what it costs to file a case. Court staff can confirm local rules on notice periods and where a motion about a deposition is filed, but not whether a deposition is a good idea in a particular case.
Points to carry away
- Federal Rule of Civil Procedure 30 requires reasonable written notice to every other party, stating the time, place and the deponent's name if known.
- A deposition is limited to one day of seven hours unless the parties agree otherwise or the court allows more.
- Each side may take ten depositions before needing leave of court.
- A non-party witness must be subpoenaed; a party is compelled by the notice alone.
- Most objections are noted on the record and the witness answers, leaving the ruling for the judge if the passage is later offered.
Questions readers ask
Does a judge attend a deposition?
No. A deposition happens in a conference room or an office, with the parties, the witness and an officer authorized to administer oaths, usually a certified court reporter. Nobody rules on objections in the moment. If a dispute cannot be resolved between the participants, the questioning either moves on or the deposition is suspended so the issue can be taken to the court. That absence of a referee is why the transcript matters so much: what is said cannot be edited later, only explained.
Can the witness refuse to answer a question?
Only in narrow circumstances. A witness may refuse in order to preserve a privilege, to enforce a limitation the court has already imposed, or where the questioning has become so abusive that the deposition should be suspended. Refusing simply because a question is uncomfortable or seems irrelevant is not permitted, and a witness who does so can be ordered back for a second session and made to pay the cost of it. Objections are stated for the record and the answer given anyway.
Is a deposition worth the expense in a small case?
Frequently not, and the alternatives are cheaper. Reporter attendance, the written transcript and any expedited delivery are all billed separately, and a single day can cost more than the claim in a modest dispute. Written questions to a party carry no reporter fee at all. Depositions earn their cost when testimony has to be locked down before a witness disappears, when credibility will decide the case, or when a document needs to be explained by the person who wrote it.

Serving Papers and Proving You Did
Court papers must be delivered by an adult who is not a party, and the delivery must be recorded in a signed proof of service filed with the court. Personal service is handing the papers to the person. Substituted service leaves them with a competent adult at the home or workplace and then mails a copy. Service by mail requires the recipient's cooperation in most systems. Defective service can void a default judgment long after it is entered.
Objecting to a Subpoena Aimed at You
A person commanded to produce documents may serve a written objection before the earlier of the compliance date or the period set by rule, which suspends the duty to produce until a court orders otherwise. A motion to quash or modify asks the court to cancel or narrow the subpoena. Federal Rule of Civil Procedure 45 requires a court to quash a subpoena that allows unreasonable time, exceeds geographic limits, demands privileged material, or imposes undue burden.
Asking the Court for an Interpreter
State and federal courts appoint interpreters for parties and witnesses who cannot follow proceedings in English, and for people who are deaf or hard of hearing. In federal court 28 U.S.C. 1827 directs the presiding judge to appoint a certified interpreter where available, with costs paid from judiciary funds. State courts commonly provide interpreters at no charge and ask for a request form filed in advance. A friend or relative is generally not permitted to interpret in the courtroom.
