A proceeding during which an attorney questions witness who answers under oat?

A proceeding during which an attorney questions a witness who answers under oath is known as a deposition. This legal process typically occurs during the discovery phase of a lawsuit, allowing attorneys to gather information and assess the testimony of witnesses before trial. Depositions are recorded and can be used in court if the witness is unavailable or to challenge their statements. This procedure is crucial for building a case and preparing for trial.
