my dad was involved in a car accident about 3 years ago. It has been dragging on ages. Anyway this is the situation he is now. The firm of solicitors who have been representing him has been taken over by another firm. This firm has said they cannot represent my dad as they are the solicitors that are representing the other person involved in the accident. They have now disclosed to him that they sent all his private medical notes to this other person by accident. Is this right, what can he do?
