De jure
Latin expression, roughly meaning 'by law', often opposed to 'de facto', meaning 'in fact' or 'in practice' / From Wikipedia, the free encyclopedia
De jure is an expression from the Latin words meaning "in law".[1]
It is often used in contrast to de facto (which means "in fact", or "in practice") when talking about law, governance, or technique. When talking about law, "de jure" is used to describe what the law says, and "de facto" is used to describe what actually happens.
