Deposition
Sworn out-of-court testimony taken during discovery and recorded verbatim for later use at trial or to impeach.
A deposition is live, sworn testimony taken outside the courtroom during the discovery phase of a case. Under Federal Rule of Civil Procedure 30, a party notices the deposition of a witness (a party or a non-party, the latter typically compelled by subpoena), and the witness answers questions from opposing counsel under oath, with a court reporter transcribing every word and video recording increasingly common. There is no judge in the room, so objections are noted for the record but rarely stop the questioning outright; the witness generally must still answer unless privilege is at stake.
Depositions serve several purposes at once: they let counsel discover facts and documents the witness knows about, they lock the witness into a version of events that can later be used to impeach them if their trial testimony shifts, and they let attorneys assess in person how a witness will read to a jury, which is often as important as what the witness actually says. Depositions are expensive relative to written discovery, so they are typically sequenced after interrogatories and document production have narrowed the key issues and identified the most important witnesses.
A deposition is one of the richest information-gain events in a case, capable of resolving disputed facts, exposing contradictions with earlier written discovery, or revealing an unexpectedly strong or weak witness. Juricratic treats deposition outcomes as evidence that updates the credibility and factual-strength dimensions of the modeled case state, letting a user see how a particular admission or contradiction shifts the simulated distribution of outcomes rather than just noting it in a memo. A single damaging admission can move the modeled range more than months of paper discovery, which is exactly why the update should be traceable back to the specific transcript line that caused it.
How it actually shows up
Litigators plan deposition sequencing strategically, often saving the most important witnesses for last so earlier testimony can be used to box them in. Defense counsel prepare witnesses extensively beforehand, while plaintiffs' counsel use depositions to test the opposing theory of the case and gather sound bites for summary judgment or trial. Because transcripts become part of the permanent record, every answer carries real downstream risk.
- How long does a deposition typically take?
- Federal Rule 30 limits a deposition to one day of seven hours absent agreement or court order, though complex cases can involve multiple sessions or witnesses with expanded time by stipulation. Simple fact-witness depositions may run only a few hours, while a key party or expert deposition often uses most or all of the allotted time.
- Can a witness refuse to answer a deposition question?
- Generally no, except to preserve a privilege such as attorney-client privilege, or to enforce a limitation previously ordered by the court. Counsel can object on the record for other grounds, like relevance or form, but the witness typically must still answer, with the objection preserved for a later ruling if needed.
- What is the difference between a deposition and interrogatories?
- A deposition is live, oral, sworn testimony that counsel can follow up on in real time and that captures demeanor and spontaneity. Interrogatories are written questions answered in writing, usually crafted carefully with attorney help, cheaper to obtain, but far less revealing about how a witness will actually perform under pressure.
