An Arizona Subpoena is a legal document issued by a court in the state of Arizona to compel an individual or organization to appear in court to provide testimony or to produce evidence. There are three types of Arizona Subpoena: a subpoena duces tecum, a subpoena ad testificandum, and a subpoena quash. A subpoena duces tecum requires a witness to produce documents or other tangible evidence in court. A subpoena ad testificandum requires a witness to appear in court and provide testimony. A subpoena quash is a motion to suppress a subpoena issued in error, or to modify its scope or terms.
