A Texas Subpoena to Testify Before Grand Jury is a legal document that orders a person to appear before a grand jury and give testimony relevant to a case. It is issued by a court (usually a state district court) and requires the recipient to appear before the grand jury at a specific time and location. In Texas, there are two main types of subpoenas that can be issued to compel someone to testify before a grand jury: a civil subpoena and a criminal subpoena. A civil subpoena is issued by a court in a civil lawsuit and requires the recipient to appear before the grand jury and provide testimony relevant to the case. This type of subpoena is typically issued when the plaintiff or defendant in a civil case needs to provide testimony to the grand jury. A criminal subpoena is issued by a court when there is a criminal investigation or prosecution. This type of subpoena requires the recipient to appear before the grand jury and provide testimony relevant to the investigation or prosecution. This type of subpoena can be used to compel a witness to testify about events that he/she observed or to produce documents that are relevant to the case. In both civil and criminal cases, a person who fails to appear in response to a Texas Subpoena to Testify Before Grand Jury can be subject to penalties, including fines and/or jail time.
