An Illinois Subpoena for Deposition is a legal document issued by the court in the state of Illinois. It requires a witness to appear in court to give testimony, produce documents, or both. The subpoena is typically issued by the court in advance of a trial or hearing, and is typically served on the witness by a sheriff or other law enforcement official. There are two types of Illinois Subpoena for Deposition: a civil subpoena and a criminal subpoena. A civil subpoena is typically used to compel testimony in a civil case, while a criminal subpoena is used for a criminal matter. Both types of subpoenas require the witness to appear in court to provide testimony or produce documents. Failure to comply with the subpoena can result in fines or other legal sanctions.
