First things first. Go back to your auto accident attorney and find out what happened. It's most probably a mix-up which he/she should be able to explain and straighten out. But if not a simple mix-up and your attorney screwed up, you may have a cause of action against that attorney. Again, first things first. Don't jump to conclusions based upon a credit report, as they are notoriously incorrect a large percentage of the time.

You have to ask your lawyer for the cancelled checks and contest it with the credit reporting agency.
You can also have your lawyer write the providers and ask them to have the derogatory info removed.
