A Vermont Subpoena to Testify at a Deposition in a Bankruptcy Case (or Adversary Proceeding) is a legal document issued by a court that orders an individual to appear at a deposition in a bankruptcy or adversary proceeding and give sworn testimony. It is a formal order from the court and is enforceable by law. There are two types of Vermont Subpoenas to Testify at a Deposition in a Bankruptcy Case (or Adversary Proceeding): a Subpoena Ducks Cecum and a Subpoena Ad Testificandum. A Subpoena Ducks Cecum is a written order issued by the court that requires a witness to bring documents, records, or other tangible objects to a deposition. A Subpoena Ad Testificandum is a written order issued by the court that requires a witness to appear at a deposition and give sworn testimony. Both types of Subpoenas must include the name and address of the witness, the date, time, and place of the deposition, and the name of the court from which the Subpoena is issued. The Subpoena must also be served on the witness before the deposition.
