The Personal Property Security Act (PPSA) outlines rules for security interests in personal property. At law, when personal property is attached to real property, it becomes a "fixture." Under the old PPSA legislative scheme, a Notice of Security Interest (NOSI) would be registered on title to indicate a security interest in a fixture, often when the fixture is leased or under a rent-to-own arrangement. Common examples of rented fixtures include furnaces, air conditioners, water heaters, and water softeners.  The government has made changes to the legislation because NOSIs were being registered without the knowledge and consent of the homeowner, and sometimes fraudulently.
