An Arizona Single-Member LLC Operating Agreement catalogs a detailed composition of rules and protocols regarding a company that is held by a single owing party. Information on the business as a limited liability company can be established and further defined within the paperwork. The document also clarifies designated approaches to how the different aspects of the company’s operation will be carried out. The Arizona government does not require the form to institute formal limited liability designation for a company, but it can be a valuable instrument to retain for legal purposes.
