What are you meant to do if you are involved in an accident. Ok on the 5th of last month i was involved in a prang with a car. We simply swapped the following details Names, contact details and license number. Today i received a letter from his insurance brokers asking to supply a cheque to cover the costs of the repair and attached is a quotation for the repairs. A friend said i should have told them who i was insured with so the letter would have gone directly to them. However i thought their insurance company could find out who i was insured with and taken it up directly with my insurance company. Are you meant to advise the other person who you are insured with at an accident?
