A Wisconsin Subpoena is a legal document issued by a court or other government agency that requires a person to appear in court or produce certain documents or other evidence. Wisconsin Subpoenas are often used to compel a witness to testify at a trial or to compel a party to produce documents or other evidence relevant to a case. The most common types of Wisconsin Subpoenas include a Subpoena Ducks Cecum, which requires a person to produce certain documents or other evidence; a Subpoena Ad Testificandum, which requires a person to appear and testify in court; and a Subpoena Ad Testificandum and Ducks Cecum, which requires a person to both appear and produce the requested documents or other evidence.
