Definitions and the 1957 Act
Occupiers' liability revolves around who controls premises rather than who actually lives there. The key test from Wheat v E Lacon & Co (1966) asks whether someone has "sufficient degree of control over the premises" to owe visitors a duty of care.
The 1957 Occupiers' Liability Act created a common duty of care for all lawful visitors, which was much fairer than before when different types of visitors got different protection levels. Under section 2(2), occupiers must "take such care as in all circumstances is reasonable to see the visitor will be reasonably safe."
Visitors include anyone with express or implied permission to be there - from invited guests to people with statutory rights. However, it's surprisingly easy to become a trespasser by exceeding your permission, which creates uncertainty about when someone's status changes.
Quick Check: The law uses an objective test - occupiers just need to do what's reasonable, not eliminate every possible danger.
