Under the PING mnemonic, which category indicates creation by prescription?

• A. Prescription by AD
• B. Implication from an existing easement
• C. Necessity
• D. Grant

Answer: (A)

The key idea is that easements can be created not just by written grant, but also through long, open, adverse use of someone else’s land. That path is known as prescription, and in many outlines it’s described as Prescription by adverse use (AD). So the category that reflects creation by prescription is the Prescription route, specifically Prescription by AD. This stands in contrast to the other routes: Implication from an existing easement reflects an easement inferred from prior use or necessity, Necessity creates an easement due to landlocking, and Grant arises from an express grant or deed. The prescription path requires actual, continuous, open, and adverse use for the statutory period to establish a right.
