An easement is an interest in land that is owned by another person and gives the easement holder or easement owner the right to use or control the other person’s land in some limited way—such as the right to drive across another person’s private property to access a public highway or other public road (an ingress-and-egress easement).

There are many different types of easements, depending on the nature of the use of the land—such light-and-air easements; mineral easements; timber easements; noise easements; and railroad easements—and how the easement was acquired—an express easement; an implied easement; a prescriptive easement; an easement by necessity; or an easement by estoppel, for example.

There are also negative easements that prohibit the owner of a property (the servient-estate) from doing something, such as building a home or structure that blocks the view or sunlight for an easement holder—often an adjoining property owner (the dominant estate).

Public utility companies (gas, electricity, telephone, water, sewer, cable, etc.) often have easements to place utility transmission, distribution, or power lines on private property and access them for installation, repair, and maintenance.

Laws regarding easements vary from state to state and may be located in a state’s court opinions (also known as its common law or case law) or in its statutes.

In Wyoming, easements are recognized as a legal interest in land that allows the holder to use the land of another for a specific purpose. Types of easements in Wyoming include ingress and egress, light and air, mineral, timber, noise, and railroad easements, among others. Easements can be established in various ways, such as expressly through a written agreement, impliedly by longstanding use, by necessity for access to landlocked property, or by prescription through continuous and uninterrupted use over a certain period. Negative easements restrict the landowner from performing certain actions that could affect the easement holder's rights, such as obstructing a view or sunlight. Public utility companies often have statutory easements that allow them to install and maintain infrastructure on private property. Wyoming's laws on easements are derived from both statutory law and common law (court opinions), and the specifics of creating, transferring, and terminating easements, as well as resolving disputes, are governed by these legal sources. An attorney can provide detailed advice on easement rights and obligations in Wyoming, tailored to the specific circumstances of the easement in question.
