The victim of a slip and fall accident will be the plaintiff in a legal case against the party responsible for maintaining the property where the fall occurred. The burden of proof requires a plaintiff to show that the property owner or manager was at fault for the conditions that caused your fall and that the conditions directly caused your injuries. Finally, the injury must have resulted in damages. Although evidence varies from case to case, a plaintiff generally needs pictures of the accident scene, surveillance video, pictures of injuries, witness testimony if available, property maintenance records and medical records.
