A Missouri Subpoena, often referred to as a “subpoena duces tecum”, is a written command issued by a court or other legal authority, requiring a person to appear in court and bring documents or other tangible items relevant to a legal proceeding. A Missouri Subpoena can be used to gather evidence, compel testimony, or both. There are two main types of Missouri Subpoenas: a Deposition Subpoena and a Trial Subpoena. A Deposition Subpoena is used to command a witness to appear and give testimony in a deposition, while a Trial Subpoena is used to command a witness to appear and give testimony in a court trial. Both types of Missouri Subpoena must be served upon the witness prior to the scheduled court appearance.
