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 stationary, or 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 personalty 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 rights of the land itself.^[clarify]

The terms real estate and real property are used primarily in common law, while civil law jurisdictions refer instead to immovable property.
