Licensees

Extracted from the Wikipedia article Licensee.
Where licensees are present, activities conducted on the land by or at the behest of the owner of the land must be conducted with the care that a prudent person would show. A duty to warn arises if there is a harmful condition on the land that is hidden from the licensee, so long as the landowner knows of this condition. The licensee falls between the anticipated or discovered trespasser and the invitee on the sliding scale of tort liability assessed to landowners. Whereas the anticipated trespasser needs to be protected from known man made conditions capable of causing death or serious injury, the licensee must be warned of all known dangers. However, unlike an invitee, a licensee has no standing to sue for dangerous conditions that "should have been" discovered by the property owner but were not actually known to the owner.
