As with any type of accident where another person is negligent, the burden to prove negligence is important. Unlike in an auto accident, for instance, a slip and fall accident claim can be extremely complicated because you must prove the property owner had prior knowledge of the hazard and had time to reasonably address the hazard. This is to avoid holding the property owner accountable for instances where a “new” hazard causes an injury, such as if, for example, someone drops a bottle of pickles in a supermarket and the person behind them slips in the juice.
