Personal injury includes injuries to the body, mind or emotions, as opposed to an injury to property. If the negligence of another person can be proved, the person who is injured may be entitled to monetary compensation from that person who was negligent. Attorneys often represent clients on a contingency basis, in which the attorneys fee is a percentage of the compensation the plaintiff receives, payable when the case is resolved. Cases involving people who have suffered an injury for which someone else (an individual or business) may be legally liable -- may include injuries caused by car accidents, medical malpractice, dog bites, slip and fall incidents, and emotional distress.
