It is not a secret that a car accident makes your life very difficult. Not only might you be injured but also dealing with relevant insurance companies. Other parties are the doctors, lawyers, driver and you might not even have a working vehicle yet. The period it you fine a case should be within 7 days of the accident. This is subject to respect accident rules in your county. But the bottom line is, it should be as soon as possible after you've been involved in an accident.
