You should consult a personal injury attorney immediately. Often times, the insurance company will call you the day of or the day after the accident to request a statement from you. Most often they will request that the statement be recorded. This statement may be used against you at a later date. Sometimes people are on medications that affect their ability to recall events at that time. Further, the insurance company will request that you sign authorizations so that they may obtain information about you. An attorney can determine if the authorizations are proper and allow the insurance company to obtain and review only information the law entitles them to review. Also, the sooner you hire a personal injury attorney, the sooner witnesses statements can be obtained and testimony from those witnesses preserved. The more time that passes between the accident and contacting the witnesses the more likely it is that the witness may not recall specific facts that would be helpful to your case. Finally, hiring an attorney right away allows you to focus on treatment and getting better. An attorney will deal with the insurance companies and ensure that the benefits you have paid for you are receiving.
