A dangerous condition the property owner actually knew about or reasonably should have discovered.

In a personal injury case (premises liability):
Proving a hazard was known or should have been known is often critical to winning a slip-and-fall or trip-and-fall case.

What to know:

• Evidence like prior complaints, inspection logs, or video footage can show how long a condition existed.

• “Open and obvious” conditions may reduce or defeat liability in some states.
