Hawaii Summons is a legal process in the state of Hawaii to compel an individual or entity to appear in court or respond to a lawsuit. Summons can be issued by the court or the Plaintiff in a civil lawsuit. There are three types of Hawaii Summons: Summons in a Complaint, Summons on a Third-Party Complaint, and Summons on an Amendment. Summons in a Complaint is the initial summons issued to the Defendant in a civil lawsuit. Summons on a Third-Party Complaint is issued when a third party is added to a civil lawsuit. Summons on an Amendment is issued when a Plaintiff amends the original complaint in a civil lawsuit. The summons must be served on the Defendant in person or by mail, and the Defendant must respond within a certain period of time.
