A New Jersey Subpoena Ad Testificandum (Request Someone's Testimony in Court) is a document issued by a court in the state of New Jersey that orders a person to appear and testify in a court of law. It is typically used to compel a person to give testimony in a criminal or civil case. The subpoena may also be used to request documents or other evidence from the person. There are two types of New Jersey Subpoena Ad Testificandum: a Subpoena Ducks Cecum, which orders the person to appear and produce documents or other evidence, and a Subpoena Ad Testificandum, which orders the person to appear and testify. Both types of subpoenas must be served on the person in accordance with New Jersey rules of civil procedure. Failure to comply with a subpoena can result in legal consequences.
