Real estate is a legal term (in some jurisdictions, notably in the USA, United Kingdom, Canada, and Australia) that encompasses land along with anything permanently affixed to the land, such as buildings, specifically property that is fixed in location. Real estate law is the body of regulations and legal codes which pertain to such matters under a particular jurisdiction. Real estate is often considered synonymous with real property (also sometimes called realty), in contrast with personal property (also sometimes called chattel or personality under chattel law or personal property law).
