In order to file a slip and fall claim against a property owner, the injured party must be able to prove that he or she was not aware of the hazardous condition that caused the injury. In most injury cases, the standard that is used is whether the injured person exercised the prudence that an ordinarily careful person would use in a similar situation. The injured person must also be able to prove that the property owner was negligent. To do this, the victim must show that the property owner had a duty to maintain his or her property and keep it safe, and that he or she breached that duty. In order to prove that there was a breach in duty, the injured party must demonstrate that the property owner had actual or constructive knowledge of the hazard. Actual knowledge is something that is seen, heard, or otherwise known; constructive knowledge is something that the property owner should have known. The injured victim must also prove that the breach of duty caused the injury, and that the injury resulted in damages.
