A witness subpoena must be served how many hours before the hearing?

A witness subpoena must be served at least 48 hours before the hearing to ensure that the witness has adequate time to prepare for their appearance. This time frame allows the witness to fulfill various obligations, such as reviewing relevant materials or coordinating travel arrangements if necessary. The requirement is designed to promote fairness in legal proceedings by allowing all parties sufficient time to prepare for the testimony of the witness. Serving the subpoena within this period helps prevent any last-minute complications that could arise if a witness is given insufficient notice.
