A New Jersey Subpoena Ducks Cecum is a legal document issued by a court that orders the recipient to appear before the court and produce specific documents and/or other tangible items. The recipient must provide the items within a specified time frame and may be subject to penalties for failure to comply. There are two types of New Jersey Subpoena Ducks Cecum: a subpoena ad testificandum, which requires documents to be given to the court, and a subpoena duces tecum, which requires documents to be brought to the court for inspection. The documents and items requested must be relevant to the case.
