Hawaii Return of Service is a document used in Hawaii to record the service of certain documents upon an individual or entity. It is typically used in legal proceedings in order to prove that the document was correctly served. There are three types of Hawaii Return of Service forms: Summons, Subpoena, and Notice of Hearing. The Summons requires the person being served to appear in court to answer a complaint; the Subpoena is used to require the production of evidence; and the Notice of Hearing is used to inform a person of an upcoming hearing. All three forms must be signed by the person who is serving the document and returned to the court.
