Almost always, the answer is that nothing can be done. When settling your personal injury claim, insurance companies will require you to execute some type of release. They may require you to sign a formal release in which you give up all claims concerning your injury. If they do not use a separate document, the check will serve as the release. The words "full and final settlement" or some similar phrase will appear on the check. In either case, the claim is concluded when the check is issued. You will not be able to reopen negotiations or file a lawsuit, and the insurance company is not likely to pay you more money out of the goodness of its heart.
The bottom line is that accepting a settlement from the insurance company without consulting a lawyer is rarely a good idea. An experienced personal injury attorney will be able to evaluate your claim and advise you as to whether the insurance company's offer is fair. A lawyer cannot help you after you have accepted an offer. Don't let this happen. Call the Paullin Law Firm & let our experienced attorneys help you.
