In September 2011 my student son had a minor scrape with a fast-moving 'white van'. They exchanged insurance details, and the other party left hurriedly saying he had to get to a sports event. The other driver claimed against my son's insurance, although my son felt that he was not at fault, and the insurance company treated it as a knock for knock. Some 18 months later, my son has received Court Documents against him relating to a personal injury relating to this incident. I have told him to contact his insurer immediately, because I am suspicious about it, but naturally he is concerned worried and possibly frightened by this. What advice can the forum give us?
