Deposition

A deposition is an out-of-court sworn testimony session in which a witness or party to a lawsuit answers questions posed by attorneys, under oath, in the presence of a court reporter who transcribes every word. Depositions are a critical tool in the civil discovery process and allow both sides to gather information, assess witness credibility, pin down testimony, and build their cases before trial. Depositions can be taken of any person who has relevant knowledge, including the plaintiff, the defendant, eyewitnesses, and expert witnesses.

Depositions serve several strategic purposes. First, they allow attorneys to discover facts and information that might not be accessible through written discovery tools like interrogatories or document requests. Second, they lock witnesses into specific versions of events under oath — if a witness later changes their story at trial, the deposition transcript can be used to impeach their credibility. Third, depositions allow attorneys to evaluate how witnesses will come across to a jury, helping them prepare more effectively for trial.

The process of a deposition involves the witness being placed under oath and then questioned by the attorneys present. The attorney who requested the deposition asks questions first, followed by other attorneys representing other parties. The witness's own attorney may object to specific questions but generally cannot instruct the witness not to answer unless the question seeks privileged information or is clearly improper. The entire session is transcribed and later reviewed by the witness, who has an opportunity to make corrections.

Depositions are often the most revealing and important part of the pre-trial discovery process. In personal injury cases, depositions of the plaintiff will probe the details of the accident, the nature and extent of the injuries, prior medical history, and how the injuries have affected the plaintiff's life. Expert witness depositions are particularly significant because they allow both sides to fully understand the opposing expert's opinions and methodology before trial, enabling effective cross-examination strategies to be developed.
