When you set a deposition, two documents do most of the work: the notice of deposition and the subpoena. They sound interchangeable, and attorneys often use them in the same breath, but they are not the same tool. One announces a deposition; the other compels someone to show up. Picking the wrong one (or skipping a step) is one of the most common reasons a deposition falls apart before the court reporter ever swears in a witness.
Here is what each document actually does, when you need both, and the practical traps that catch even experienced practitioners.
The short version
- A notice of deposition tells everyone in the case when, where, and how a deposition will happen. It is required for essentially every deposition.
- A subpoena is a court's command to a person to appear (and sometimes to bring documents). It is the only thing that legally forces attendance.
- For a party (or a party's officer/managing agent), a notice alone is usually enough to compel attendance.
- For a non-party witness, you almost always need both: notice to the case and a subpoena to the witness.
What a notice of deposition does
Under the Federal Rules (and parallel state rules), Rule 30(b)(1) requires a party to give "reasonable written notice" to every other party before taking a deposition. The notice typically states:
- The name and address of the deponent (or, for an organization, the matters for examination under Rule 30(b)(6))
- The date, time, and location (or remote/videoconference platform)
- The method of recording, stenographic, audio, or video
- Whether documents are requested from a party deponent
The notice is directed at the parties and their counsel, not at the witness personally. Its job is to give the other side a fair chance to attend, prepare, and object. A notice does not, by itself, give a court the power to sanction a stranger to the lawsuit who simply ignores it.
What a subpoena does
A subpoena is issued under Rule 45 in federal cases (and equivalent state statutes). It is a formal command backed by the court's contempt power. Subpoenas come in flavors:
- Subpoena ad testificandum — commands a person to appear and testify.
- Subpoena duces tecum — commands a person to produce documents or things, with or without live testimony.
Because it carries real teeth (a witness who ignores a valid subpoena can face contempt), Rule 45 imposes strict requirements: proper issuance from the right court, valid service, geographic limits (generally within 100 miles of where the person lives, works, or regularly transacts business), tender of witness fees and mileage where required, and a reasonable time to comply.
Party vs. non-party: the dividing line
This is the distinction that controls which documents you send.
Deposing a party. If you want to depose the opposing party, a designated corporate representative, or a party's officer, director, or managing agent, a properly served notice generally compels attendance. The party's lawyer is obligated to produce that person. You do not ordinarily need a subpoena.
Deposing a non-party. A former employee, a treating physician, an eyewitness, the records custodian at an unrelated company, none of these people answer to the parties' lawyers. To make them appear, you serve a subpoena on the witness and a notice on the other parties. Skip the subpoena and the witness has every right to no-show with no consequence.
A useful gut check: ask "Does this person answer to a lawyer already in the case?" If yes, notice may be enough. If no, you need a subpoena.
Documents: notice-to-produce vs. duces tecum
- To get documents from a party at a deposition, attach a Rule 34 request or use the notice itself.
- To get documents from a non-party, use a subpoena duces tecum. You cannot use a plain notice to force a stranger to bring records.
Practical pitfalls that derail depositions
- Short notice. "Reasonable" is not defined in days. Many practitioners treat a week or more as safe for routine depositions; tight timelines invite a motion for a protective order. Check your local rules and standing orders, some jurisdictions specify minimums.
- Forgetting the subpoena for a non-party. The single most common reason a witness rightfully fails to appear.
- Bad service. A subpoena usually requires personal service on the witness; a notice goes to counsel via the normal e-service channels. Don't mix them up.
- Missing witness fees. Federal non-party witnesses are entitled to a statutory daily attendance fee plus mileage, tendered at service. Omitting it can void the subpoena.
- Geographic limits. You generally cannot drag a non-party witness hundreds of miles to testify. Plan the location, or arrange remote testimony, accordingly.
- No court reporter lined up. None of this matters if there's no qualified, neutral officer to administer the oath and produce the transcript.
Lock in the logistics early
Once your notice and any subpoena are squared away, the deposition still needs a competent court reporter, and, where useful, a videographer or remote-platform host. Availability tightens fast around discovery deadlines, especially for specialized work like realtime, certified videography, or out-of-area coverage.
Rates vary widely by region, format, and turnaround, so it pays to compare a few professionals rather than defaulting to the first name you find. On courtreporter.co you can browse and compare court reporters nationwide for free, check coverage areas and services, and reach out directly, no account or fee required, so the reporter is the one part of your deposition you never have to scramble for.
Bottom line
Think of the notice as the announcement and the subpoena as the command. Parties respond to notices; non-parties respond to subpoenas. Send the right document to the right person, mind service and timing, and confirm your reporter early, and your deposition will go off as planned.
