Which term best describes the legal right to control access to a piece of property?

The term that best describes the legal right to control access to a piece of property is possession. Possession indicates that an individual or entity has physical control or occupancy of the property, which inherently includes the authority to regulate who can enter or use that property. This concept is foundational in property law, as possession gives the holder a recognized right to exclude others from accessing the property unless they have permission.

While other terms like use, disposition, and enjoyment relate to different aspects of property rights, they do not precisely capture the legal authority over access. For instance, use refers to how a property can be utilized, disposition involves the rights to transfer or sell the property, and enjoyment pertains to the rights of the owner to enjoy the benefits derived from the property. Each of these plays a significant role in property rights but does not specifically convey the control aspect over access as possession does.
