I am planning to sell my old Maruti 800 car , which is in my father's name and am buying a new car in my name. I have a 50% NCB as mentioned in the Insurance policy of my old car, which is valid upto 31-03-09. If I handover the Insurance policy along with RC book to buyer of my old car, can I still enjoy the NCB benefit on new car in my name? My new car will be delivered to me with in 2 months. What other papers I need to sought from the buyer so that I do not face in concequencies after a sale date?
