What is the French term for "of law"?

The French term "de jure" translates to "of law" and refers to something that is established by law or in accordance with the law. This phrase is often used in legal contexts to distinguish between situations that exist according to legal frameworks versus those that exist in practice or fact.

In contrast to "de facto," which denotes what is true in fact, regardless of whether it is officially sanctioned, "de jure" implies a recognition of legality or formal establishment. For instance, a situation that is de jure may be supported by legislation or constitution, even if it does not play out that way in practice.

The other terms presented do not have this legal connotation. "Pro bono" refers to professional work undertaken voluntarily and without payment, typically related to legal services provided for public good. "Subpoena" is a legal document ordering someone to attend a court proceeding, and it does not convey the notion of legality or law directly. Therefore, "de jure" is the correct term for "of law."
