A Texas Subpoena to Testify at a Deposition in a Criminal Case is a court order requiring a witness to appear and testify at a deposition in a criminal case. This type of subpoena is issued by the court and delivered to the witness by a law enforcement officer. Depending on the jurisdiction, the subpoena may be issued by a District Attorney, a grand jury, or the court itself. The Texas Subpoena to Testify at a Deposition in a Criminal Case may be issued for either a defendant or a witness, and requires the recipient to appear at the deposition and answer questions. This type of subpoena is often used in cases involving serious felonies, such as murder or drug trafficking. There are two types of Texas Subpoena to Testify at a Deposition in a Criminal Case: a subpoena duces tecum, which requires the witness to bring specific documents or records to the deposition, and a subpoena ad testificandum, which requires the witness to appear and answer questions. Both types of subpoenas are legally binding and must be complied with or the recipient may face criminal charges.
