What is the primary function of posting private property signs?

The primary function of posting private property signs is to prevent claims of permissive use. When property is clearly marked as private, it communicates to others that the landowner does not grant permission for anyone to trespass or use the property without consent. This is important because if someone uses a property without permission and the owner does not take steps to restrict that use, they could potentially lose their rights to the property through a legal doctrine known as adverse possession.

By clearly marking the property, the owner can assert their rights and deter unauthorized use, thereby protecting their interests in the property. This signage can serve as a means to effectively communicate boundaries and the owner’s intent regarding use, which is crucial in the context of property rights.

The other options, while related to property law, do not address the direct intent of posting private property signs in the same way that preventing claims of permissive use does. For example, enhancing marketability of title, granting legal easements, or establishing a license are different legal concepts that do not pertain to the primary purpose of private property signage.
