Heres why. When it comes to settling car insurance claims, auto insurance companies will only cover what is listed in any given policy, such as the vehicle repair costs and medical bills. Unfortunately, even a generous insurance policy might not offer compensation for pain and suffering or loss of consortium, that is, the loss of a spouse, child, or the ability to have a normal relationship with a spouse, child, or even a sibling. You may also need an attorney if you only carried the legal minimum. Legal minimums only cover third party damages, but not the "totaling" of a vehicle.
In cases such as these, the cards might be stacked against you. Your ability to collect a fair amount from the other parties insurance company may be slim to none if you attempt to resolve the issue on your own. So contact an experienced auto accident attorney for advice on your specific case.
