History and Meaning of Addendum

An addendum, in legal terms, is a document added to a complete legal agreement that serves the purpose of clarifying or changing a portion of the original document. It is used mainly for documenting negotiations between parties, particularly in real estate transactions.

The term “addendum” comes from the Latin word “addere,” which means “to add.” An addendum is designed to clarify or supplement a document that already exists, rather than creating an entirely new document. It is a legal way of modifying a contract rather than starting the process anew.
