A Texas Subpoena is a legal document issued by a court or other authority in Texas, ordering a person to appear in court or produce documents. It is a civil process issued to compel the appearance of a witness to give testimony or to compel the production of documents. There are two main types of Texas Subpoenas: a Subpoena to Appear and a Subpoena Ducks Cecum. A Subpoena to Appear orders the recipient to appear in court and give testimony at a particular time and place. A Subpoena Ducks Cecum orders the recipient to produce documents or other tangible evidence to the court for inspection.
