Hello, My advice would be to contact your insurance company. They can begin negotiations and work on your behalf to get your vehicle back to its pre-accident state. As far as the notarization goes, I'm unclear on what you actually had notarized or what it's exact purpose was. Again, I would explain the situation in full to your insurance company. They should be able to advise you on your next steps. Good luck and don't hesitate to ask
if you have any questions.
