Real estate is a legal term (in some jurisdictions, notably in the USA, Unites 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 and include things such as commercial and residential real property transactions. 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).However, in some situations the term "real estate" refers to the land and fixtures together, as distinguished from "real property" referring to ownership of land and appurtenances, including anything of a permanent nature such as structures, trees, minerals, and the interest, benefits, and inherent rights thereof. Real property is typically considered to be Immovable property. The terms real estate and real property are used primarily in common law, while civil law jurisdictions refer instead to immovable property.
