“Blackacre is the most celebrated tract of land in the world of the law …. Blackacre is wholly mythical, yet totally real. It is a concept, living in the realm of the mind and doubly valuable since much of the law of property has the same type of reality.” John E. Cribbet, Principles of the Law of Property 2 (2d ed. 1975).
blackacre
Blackacre. A fictitious tract of land used in legal discourse (esp. law-school hypotheticals) to discuss real-property issues. • When another tract of land is needed in a hypothetical, it is often termed “Whiteacre.”
