A Tennessee Subpoena To Appear and Testify at a Hearing or Trial in a Civil Action is a legal document issued by a Tennessee court that orders a person to appear and testify in a civil action. It can be issued by any court with jurisdiction over the action, including state and federal courts. The subpoena can also be used to require the production of documents or tangible things. There are two types of Tennessee Subpoena To Appear and Testify at a Hearing or Trial in a Civil Action: a Subpoena Ducks Cecum and a Subpoena Ad Testificandum. A Subpoena Ducks Cecum orders a person to produce specific documents or tangible things. A Subpoena Ad Testificandum orders a person to appear and testify. In both cases, the person who receives the subpoena must appear and testify in court. The subpoena will include the date, time, and location of the hearing or trial; the title of the action; the court issuing the subpoena; and a description of the documents or tangible things to be produced, if applicable. The person must also bring any documents or tangible things that are specified in the subpoena. The person who receives the subpoena must appear in court on the date and time specified in the subpoena or risk being held in contempt of court.
