If you went through the claims process and signed an agreement with the insurer, you likely will not be able to reopen a motor vehicle accident claim. This is because, during this process, you probably have signed release forms that set the terms of the settlement and finalize liability payments. Plus, signing these forms also means you agree that your claim has resolved, and you give up your right to file a lawsuit against the insurance company. These agreements are generally signed in exchange for money for the harm and losses you endured in the car accident. Because the release is a legally binding document, courts will usually uphold them. For these reasons, before you sign any release forms, review them with an experienced car accident attorney. These lawyers can verify whether the insurance company is trying to provide you with a lowball offer and if there is money you can still obtain.
