Arizona Summons is a legal document that is issued by a court of law in the State of Arizona. It is a formal notice to appear in court and is used to initiate a civil or criminal case. There are two types of Arizona Summons: Summons to Answer and Summons to Appear. A Summons to Answer is used to initiate a civil case and requires the defendant to answer the complaint filed by the plaintiff. A Summons to Appear is used to initiate a criminal case and requires the defendant to appear before a judge or magistrate. Arizona Summons must be served on the defendant in person or by mail, depending on the type of case. Upon service, the defendant must appear in court on the date specified in the summons. Failure to appear may result in a warrant for their arrest.
