In the law the term whereas also is used as the introductory word to a recital in a formal document. A recital contains words of introduction to a contract, statute, proclamation, or other writing. In a contract a whereas clause is an introductory statement that means "considering that" or "that being the case." The clause explains the reasons for the execution of the contract and, in some cases, describes its purpose. The whereas clause may properly be used in interpreting the contract. However, it is not an essential component for its operative provisions.
