Air rightsIn real estate, air rights are the property interest in the "space" above the earth's surface. Generally speaking, owning or renting land or a building includes the right to use and build in the space above the land without interference by others. This legal concept is encoded in the Latin phrase Cuius est solum, eius est usque ad coelum et ad inferos ("Whoever owns the soil, it is theirs up to Heaven and down to Hell.
Prior-appropriation water rightsIn the American legal system, prior appropriation water rights is the doctrine that the first person to take a quantity of water from a water source for "beneficial use" (agricultural, industrial or household) has the right to continue to use that quantity of water for that purpose. Subsequent users can take the remaining water for their own use if they do not impinge on the rights of previous users. The doctrine is sometimes summarized, "first in time, first in right".
EasementAn easement is a nonpossessory right to use and/or enter onto the real property of another without possessing it. It is "best typified in the right of way which one landowner, A, may enjoy over the land of another, B". An easement is a property right and type of incorporeal property in itself at common law in most jurisdictions. An easement is similar to real covenants and equitable servitudes. In the United States, the Restatement (Third) of Property takes steps to merge these concepts as servitudes.
Crown landCrown land (sometimes spelled crownland), also known as royal domain, is a territorial area belonging to the monarch, who personifies the Crown. It is the equivalent of an entailed estate and passes with the monarchy, being inseparable from it. Today, in Commonwealth realms such as Canada and Australia, crown land is considered public land and is apart from the monarch's private estate.
Title (property)In property law, title is an intangible construct representing a bundle of rights in (to) a piece of property in which a party may own either a legal interest or equitable interest. The rights in the bundle may be separated and held by different parties. It may also refer to a formal document, such as a deed, that serves as evidence of ownership. Conveyance of the document (transfer of title to the property) may be required in order to transfer ownership in the property to another person.
