According to Investopedia: an eviction is the civil process by which a landlord may legally remove a tenant from their rental property. Eviction may occur when the tenant stops paying rent, when the terms of the rental agreement are breached, or in other situations permitted by law.
Evictions in the United States are governed by individual states and certain municipalities. Landlords are required to inform tenants they are being evicted with a notice that specifies the reason for the eviction and the number of days before eviction proceedings begin.
In Arizona an eviction may also occur after the property owner defaults on their mortgage and the property is sold at a public auction. The new owner may evict the old owner.
