A more thorough explanation: Formality refers to a prescribed or customary practice or procedure that is required or expected in a particular situation, often involving adherence to established rules, conventions, or protocols. In a legal context, formality may refer to the proper execution or observance of legal requirements, such as the formalities necessary for the validity of a contract or the formalities involved in legal proceedings.
Example: The signing of the contract was merely a formality, as all terms had already been agreed upon by both parties.
