A Nevada Subpoena for Appearance at Deposition (without Documents) is a court-issued document that orders a witness to appear in court and testify in a trial or deposition. It can be issued by a Nevada court or by a party to a lawsuit. The subpoena requires the witness to appear at a specified time, date, and place and to answer any questions posed by the parties to the lawsuit. The Nevada subpoena may be served either in person or through mail. There are two types of Nevada Subpoena for Appearance at Deposition (without Documents): Subpoena Ducks Cecum and Subpoena Ad Testificandum. Subpoena Ducks Cecum orders the witness to bring to the deposition or trial certain documents or records. Subpoena Ad Testificandum orders the witness to appear in court or deposition and to answer any questions posed by the parties to the lawsuit.
