A Tennessee Subpoena To Testify At A Deposition Or To Produce Documents In A Civil Action is a judicial document issued by a court that requires an individual to appear in court to provide testimony or produce documents in a civil action. In Tennessee, the subpoena is issued by a jury commissioner or a court clerk and must be served in person or by mail to the individual or entity specified in the subpoena. There are two types of Tennessee Subpoena To Testify At A Deposition: a subpoena ad testificandum, which requires the recipient to appear and testify at a deposition, and a subpoena duces tecum, which requires the recipient to produce documents or other tangible evidence. Both types of subpoenas must include the date, time, and location of the deposition, as well as a description of the documents or other evidence to be produced.
