other driver had a lawyer and my insurance co settle with him for $100,000

first please excuse the typing and word usage as I am using speech to text technology In answering your question I am assuming the issue concerns the personal injury liability settlement with the plaintiff and his or her lawyer. when an insurance company settles a claim the release signed by the plaintiff forever releases the insured, the driver of the insured's vehicle and the insurance company from any future liability for the accident. that is part of the deal. it would only be under the most unusual circumstance where you would have excess liability. if that were to happen you would be clearly notified by your insurance company and they would probably need your permission. I am quite certain that did not occur in your situation, but check with your insurance adjuster handling the claim. I am certain they will explain all of this to you. Since I do not know the facts of your claim and maybe it falls in that very very rare and unusual exception, you may to consult with a lawyer if the insurance adjusters answer is not clear.
