Arizona Acceptance of Service is a process by which a person is served with legal documents, such as a summons, complaint, or notice. This process, which is also known as service of process, is governed by the Arizona Rules of Civil Procedure. There are two types of Arizona Acceptance of Service: personal service and substituted service. Personal service is when a third-party server delivers the legal documents directly to the person to be served. The server must be 18 years of age or older, not a party to the case, and must provide proof of service to the court. Substituted service is when the server attempts to deliver the legal documents to the person to be served via a method other than personal service. The server must follow the rules outlined in the Arizona Rules of Civil Procedure for substituted service, including attempting to mail the documents to the person’s last known address and/or delivering them to an adult occupant of the person’s residence. If the server is unable to deliver the documents via substituted service, they must return them to the court.
