Ariz. Rev. Stat. § 33-744
At any time after expiration of the period provided for in the notice of election to forfeit, the seller may complete the forfeiture of the interest of the purchaser and persons having an interest in or a lien or encumbrance on the property, the priority of which is subordinate to that of the seller, by filing an action in the superior court in the county in which the real property is located to declare that the interest of the persons has been forfeited and to quiet title to the property in the seller. In the action, the seller shall name as defendants the purchaser and each person who, at the expiration of the period provided for in the notice of election to forfeit, had an interest in or a lien or encumbrance on the property, the priority of which was subordinate to that of the seller.
