A Wisconsin Subpoena is a document issued by a court or other legal authority in Wisconsin that compels a person to appear at a certain place and time to testify or provide evidence at a court hearing or legal proceeding. It is a legal order that requires the recipient to attend and give testimony or produce documents. There are two main types of Wisconsin Subpoenas: Subpoena Ducks Cecum (SDP) and Subpoena Ad Testificandum (SAT). The SDP requires the recipient to bring documents or other tangible evidence to the court hearing, while the SAT requires the recipient to provide testimony. Both types of Subpoenas must be served in person, in writing, and with the appropriate fees.
