A Missouri Subpoena is a legal document issued by a court of law that requires a person or entity to appear in court and produce documents or other tangible evidence relevant to a trial. There are two types of Missouri Subpoena: a Subpoena Ducks Cecum, which requires the person or entity to produce documents, and a Subpoena Ad Testificandum, which requires the person or entity to appear in court to testify. Both types of Missouri Subpoenas are issued by a court of law and must be served upon the person or entity being summoned to appear in court. Failure to comply with a Missouri Subpoena can result in court-imposed fines or other penalties.
