De facto ( /diː ˈfæktoʊ/, /deɪ/, ) is a Latin expression that means "concerning fact." In law, it often means "in practice but not necessarily ordained by law" or "in practice or actuality, but not officially established." It is commonly used in contrast to de jure (which means "concerning the law") when referring to matters of law, governance, or technique (such as standards) that are found in the common experience as created or developed without or contrary to a regulation. When discussing a legal situation, de jure designates what the law says, while de facto designates action of what happens in practice. It is analogous and similar to the expressions "for all intents and purposes" or "in fact". The term can also be used in the context of conducting activity as a "matter of course" e.g. copying an individual on an email de facto.
