A Maine Subpoena in a Criminal Case is a court order to compel individuals to appear in court to provide testimony or present evidence in a criminal case. There are two types of Maine Subpoenas in a Criminal Case: a Subpoena Ducks Cecum and a Subpoena Ad Testificandum. A Subpoena Ducks Cecum requires an individual to bring documents or other tangible items to court, while a Subpoena Ad Testificandum requires an individual to appear in court to testify. Both types of Maine Subpoena must be served on the individual and a return of service must be filed with the court. The return of service is proof that the individual was served with the Maine Subpoena in a Criminal Case.
