What is the term for the documented rights that support property access rights?

The term that accurately describes the documented rights supporting property access is Easement Rights. An easement is a legal right to use another person's land for a specified purpose, such as allowing access to a property. This can include pathways, driveways, or utility lines that enable one property owner to cross over or utilize part of another's property without owning it.

Easements are usually documented in writing and are recorded in county offices to ensure that the rights are enforceable and known to all parties, including future property owners. The existence of easement rights is crucial for maintaining access to properties that might otherwise be landlocked or difficult to reach.

While Access Rights seems logically related, it is not the standard legal term used in real estate contexts. Property Rights are broader and encompass the overall rights of ownership, and Land Use Rights refer to the rights associated with the development or use of land, which do not specifically pertain to access. Hence, Easement Rights is the most precise answer in this context.
