Consulting with your Fayette County injury attorney is the best step because the insurance company will require attention. They may need some simple documentation or they may do something extreme, like pull their offer, if there was one.
Your attorney can advise you of how to deal with the insurance company. Your next steps will depend on what stage the personal injury case was left at. It may be easier if it was close to settlement. If the case was still in preliminary stages, you will need to decide if you want to continue to pursue it.
