A prescriptive easement is a legal right to use someone else's property for a specific purpose, acquired through continuous and open use over a certain period of time, without the permission of the property owner. This form of easement is often recognized when the user has maintained uninterrupted use that is visible, notorious, and adverse to the interests of the landowner. The concept of prescriptive easements is vital in understanding property rights and the way they can be established through prolonged usage.
