Personal injury claims involve harm that is caused by another's action. Negligence is the primary cause of personal injury claims. These claims can involve car accidents, motorcycle accidents, tractor trailer accidents, premises liability, slip and falls and sporting accidents. Areas of compensation as a result of these claims can be medical expenses, lost wages, loss of earning capacity, physical pain and suffering, mental suffering and physical impairment. If the injuries as a result of an accident are catastrophic, then you may have a wrongful death claim. If gross negligence is proven, you could be awarded punitive damages. Personal injury claims must be proven - that is why it important to consult with an attorney of your own.
