What is the official permission, often revocable by the land owner, called?

The term that refers to official permission, typically revocable by the landowner, is known as a license. In land use and property law, a license grants a person or entity the right to enter or use another person's land for a specific purpose without transferring any interest in the property itself. Unlike an easement, which is a more permanent and legally binding right to use someone's property, a license is temporary and can be terminated at the discretion of the landowner. This characteristic makes a license a more flexible arrangement for both parties involved. For instance, an example of a license could be granting a friend permission to use your driveway for parking on occasion; it can be revoked anytime without significant legal ramifications. Understanding the difference between these legal permissions is crucial for anyone involved in property management or surveying.
