Probably not as much as you might think.  You may have as little as six months, and you might have as long as two years, depending on the facts of your case and who you are suing.  But there is no reason to wait, and many reasons to act right away.  If you delay, evidence may be lost forever, witnesses may forget or move, and it may become impossible to win your case.  Call a car wreck attorney right away.  If it is too early to file suit, we'll tell you that.  Otherwise, the sooner we get started the sooner we can get you the recovery you deserve.
