"De facto" is a Latin term meaning "in fact" or "in practice," used to describe situations that exist in reality, even if not officially recognized. For example, a de facto leader may hold power and influence without having formal authority or title. In legal contexts, "de facto" can refer to practices or conditions that are accepted as true or valid, despite lacking official status. For instance, a de facto marriage occurs when a couple lives together and presents themselves as married without a legal ceremony.
