de jure

[Latin dē iūre : dē, from + iūre, ablative of iūs, law.]

By right; lawful; legitimate. Generally used in contrast to De Facto; de jure connotes ‘as a matter of law,' whereas de facto connotes ‘as a matter of practice not founded upon law.'

Definition: by right
Antonyms: de facto

[Latin, In law.] Legitimate; lawful, as a matter of law. Having complied with all the requirements imposed by law.

De jure is commonly paired with de facto, which means "in fact." In the course of ordinary events, the term de jure is superfluous. For example, in everyday discourse, when one speaks of a corporation or a government, the understood meaning is a de jure corporation or a de jure government.

A de jure corporation is one that has completely fulfilled the statutory formalities imposed by state corporation law in order to be granted corporate existence. In comparison, a de facto corporation is one that has acted in good faith and would be an ordinary corporation but for failure to comply with some technical requirements.

A de jure government is the legal, legitimate government of a state and is so recognized by other states. In contrast, a de facto government is in actual possession of authority and control of the state. For example, a government that has been overthrown and has moved to another state will attain de jure status if other nations refuse to accept the legitimacy of the revolutionary government.

De jure segregation refers to intentional actions by the state to enforce racial segregation. The Jim Crow laws of the southern states, which endured until the 1960s, are examples of de jure segregation. In contrast, de facto racial segregation, which occurred in other states, was accomplished by factors apart from conscious government activity.

By the law, by right.
