A Texas Subpoena to Testify at a Deposition is a legal document issued by a court in the state of Texas. It requires an individual to appear in court and testify under oath in a deposition, which is a formal questioning process conducted by an attorney to gather information related to a legal case. The individual who receives the subpoena must answer all questions truthfully and accurately, or face criminal penalties. There are two types of Texas Subpoena to Testify at a Deposition. The first is a Subpoena Ducks Cecum, which requires the individual to appear in court and bring certain documents with them. The second type is a Subpoena ad Testificandum, which requires the individual to appear in court and testify as a witness. The process of serving a Texas Subpoena to Testify at a Deposition begins with the court issuing the subpoena and having it served on the individual by a process server.
