A Louisiana Subpoena in a Civil Case is a court-issued document that orders a person to appear in court or to provide documents or information related to a case. It is also known as a Citation or Writ of Summons. There are two types of Louisiana Subpoena in a Civil Case: a Subpoena Ducks Cecum and a Subpoena Ad Testificandum. A Subpoena Ducks Cecum orders a person to bring documents or other tangible items to court. This type of Subpoena can be issued to a party to the case, a witness, or a third party. The documents or items must be relevant to the case. A Subpoena Ad Testificandum orders a person to appear in court to testify or provide information that is relevant to the case. This type of Subpoena can be issued to a party to the case, a witness, or a third party. Both types of Louisiana Subpoena must contain the name and address of the court, the case number, the date and time the individual must appear in court or provide documents, and the penalties for failure to comply.
