An Indiana Subpoena to Testify at a Deposition in a Criminal Case is a court order requiring a witness to appear in court or in another location to answer questions from lawyers in a criminal case. This type of subpoena is issued by a court in order to secure testimony from a witness that can be used in the criminal case. There are two types of Indiana Subpoena to Testify at a Deposition in a Criminal Case: a Subpoena Ducks Cecum, which requires a witness to bring specific documents, and a Subpoena Ad Testificandum, which requires a witness to testify. Both types of subpoenas have the same general purpose but serve different functions. A Subpoena Ducks Cecum requires a witness to bring documents such as emails, photographs, or other records to the deposition, while a Subpoena Ad Testificandum requires a witness to answer questions under oath.
