The four common elements of negligence are duty, breach, causation, and damages. In a premises liability case, this usually means showing the property owner had a legal duty to keep the property reasonably safe, failed to address or warn about a hazard, that failure caused your injury, and you suffered measurable losses such as medical bills, lost wages, or pain.
