Legal Definitions - jure

The term jure is a Latin adverb meaning "by right" or "by law." It is used in legal contexts to specify the legal basis or source from which a particular right, status, or authority is derived. When you see "jure" combined with another Latin word or phrase, it indicates that the subsequent term explains *how* or *why* that right or status exists.

• Example 1: Jure Accessionis (By the law of natural accession)

  Imagine a homeowner who plants a small tree on their property. Over many years, the tree grows large and valuable. The homeowner owns that tree jure accessionis because it has naturally grown and become an integral part of their existing land. This principle means that the owner of the main property automatically acquires ownership of anything that is naturally added to it or produced by it.

• Example 2: Jure Belli (By the right or law of war)

  Consider a situation where a nation's military forces capture enemy combatants during an armed conflict. The right of that nation to detain these individuals, subject to international humanitarian law, is exercised jure belli. This means their authority to act in this manner stems directly from the established laws and customs governing warfare between states.

• Example 3: Jure Proprietatis (By right of property)

  An individual purchases a new car and receives the title of ownership. Their ability to drive that car, sell it, or prevent others from using it without permission is held jure proprietatis. This illustrates that their rights over the vehicle are a direct consequence of their legal ownership of the property itself.
