executed parol license

In property law, a license grants permission to use another's property. There are three types: bare licenses (implied permission, like entering a store), contractual licenses (permission granted for consideration, such as a movie ticket), and licenses coupled with an interest (permission to take property from another's land, like repossessing a car).1

An "executed parol license" is a term used when a landowner allows property use, and the licensee reasonably relies on this permission, often by spending money or changing their position. In such cases, the license may become irrevocable. However, this is more accurately described as a servitude created by estoppel, as it better reflects the legal process and the resulting right, which runs with the land indefinitely. The term "parol contract" refers to an oral agreement or a written one not under seal.12
