A Michigan Subpoena to Appear and Testify at a Hearing or Trial in a Civil Action is a court order that requires a person to appear in court to provide testimony or evidence related to a civil case. The person receiving the subpoena must appear at the time and place specified by the court and comply with all instructions provided. The subpoena may also require the person to bring physical evidence or documents to the hearing or trial. There are two types of Michigan Subpoena to Appear and Testify at a Hearing or Trial in a Civil Action: a Subpoena Ducks Cecum, which requires the witness to bring documents or physical evidence to the hearing or trial, and a Subpoena Ad Testificandum, which requires the witness to appear and testify but not to bring any documents or physical evidence.
