A New Jersey Information Subpoena is a legal process by which a party to a case can request information from a non-party, such as a business or individual, in order to support their case. There are two types of New Jersey Information Subpoenas: a Subpoena Ducks Cecum and a Subpoena Ad Testificandum. A Subpoena Ducks Cecum is a request for documents, while a Subpoena Ad Testificandum is a request for a witness to appear and testify before the court. Both types of subpoenas are issued by the court and must be responded to in a timely manner. Failure to respond can result in a contempt of court charge.
