Subservient tenement

An easement is the right to do something or the right to prevent something over the real property of another. At common law, an easement came to be treated as a property right in itself and is still treated as a kind of property by most jurisdictions. In some jurisdictions, another term for easement is equitable servitude, although easements do not have their origin in equity.
