Washington Subpoena is a legal document issued by a Washington court, requiring the recipient to appear in court or to produce documents or other evidence. There are two types of Washington Subpoenas: a Subpoena Ducks Cecum and a Subpoena Ad Testificandum. A Subpoena Ducks Cecum is used to compel a person to produce documents or other evidence before the court. This type of subpoena can be used in civil or criminal proceedings. A Subpoena Ad Testificandum is used to compel a person to appear in court and testify. It is commonly used in criminal proceedings and may be issued to compel a witness to testify in a trial or a grand jury hearing. In Washington State, a subpoena must be personally served upon the recipient. The subpoena must state the date, time, and place of the hearing or trial, and the name of the court. Failure to obey a subpoena may result in contempt of court charges.
