You should provide your personal injury attorney with any documents related to your case. This can include copies of medical and hospital reports and bills, police or accident or incident reports -- which often contain important eyewitness information and other contextualizing details -- and any photographs you might have of the scene of the accident, and the injury or property damage sustained. Information about any the insurer of the person who caused your injury is also extremely helpful and, if an automobile or motor vehicle accident, the insurance information for the car or vehicle you were in as well. The more information you provide to your lawyer, the better -- the more information you can provide, the easier it will be for your personal injury attorney to assess whether or not you have a viable case. If you don’t have any of the above, don’t worry -- your lawyer will be able to obtain them in investigating your claim.
