What is an example of an easement by reservation?

An easement by reservation occurs when a property owner sells a portion of their land but retains certain rights over the sold land—specifically, the right to use part of it for their own purposes. In the case of selling land to a neighbor while reserving access, the seller maintains a legal right to enter and use the area that they have sold, which illustrates the concept of an easement by reservation.

This situation is distinct from other scenarios, such as sharing a driveway, which typically involves a mutual agreement rather than a reservation of rights from a sale. Similarly, preventing an adjoining owner from using your land does not create an easement; it’s simply an exercise of property rights. Lastly, using someone's property continuously for years could potentially lead to adverse possession but does not represent an easement by reservation because it lacks the explicit legal framework or agreement that characterizes an easement. Thus, the correct choice—selling land while reserving access—accurately reflects the definition and application of an easement by reservation.
