Arizona Acceptance of Service is an official document that is used to formally acknowledge that a person has received notice of a legal action, such as a lawsuit or summons. This document is typically signed by the person receiving the notice, or by an agent or representative of the person. The document is then filed with the court or other legal authority to show that the notice has been received. There are two types of Arizona Acceptance of Service: voluntary and mandatory. Voluntary Acceptance of Service is when a person voluntarily signs the document and files it with the court. Mandatory Acceptance of Service is when the court requires the person to sign the document in order to proceed with the legal action.
