What is the legal term for a writ ordering a person to attend court?

The legal term for a writ ordering a person to attend court is a subpoena. A subpoena is a formal document that compels an individual to appear in court as a witness or to produce evidence. It is utilized in both civil and criminal cases to ensure that testimony and pertinent information are provided during legal proceedings.

In contrast, a summons is typically used to notify a defendant that a legal action has been initiated against them and that they are required to respond to the complaint. A writ of certiorari, on the other hand, is a type of order issued by a higher court to review the decisions of a lower court. An affidavit is a written statement confirmed by oath, used as evidence in court but does not require a person to attend. Thus, a subpoena specifically fulfills the function of requiring an individual to appear before the court.
