What should a homeowner do to ensure continued use of a shared driveway after a neighbor moves?

To ensure continued use of a shared driveway after a neighbor moves, filing for an easement is the most appropriate action because it formally grants one property owner the legal right to use a portion of another's property for a specific purpose, such as accessing a shared driveway. An easement is a permanent agreement that remains in effect regardless of changes in property ownership, which means that even if the neighbor selling the property allows the shared use, you can ensure that this right persists beyond their tenure.

In contrast, options like requesting a variance, getting a lease agreement, or obtaining a license do not provide the same level of security. A variance usually pertains to zoning changes and would not apply to the right of use of property. A lease agreement typically implies a temporary arrangement, which may not protect the homeowner's interests in the long term. A license can be revoked and does not establish a permanent right to access the driveway, making it the least secure option for ensuring continued use after the neighbor moves.
