What is deposition? Please explain!

It's in the explanation.

Explanation:

A deposition is a simple procedure, a session of questions asked by the opposing counsel that the witness has to answer. The focus for the witness is not on telling his or her story, but on telling the truth to the opposing counsel.

A deposition in the law of the United States, or examination for discovery in the law of Canada, involves the taking of sworn, out-of-court oral testimony of a witness that may be reduced to a written transcript for later use in court or for discovery purposes.
