The sum insured for the automobile is Insured’s Declared Value. It reflects the present market value of the automobile. If you buy a third party insurance, you get covered against third-party liability specifically. The offered coverage is unlimited for the third-party’s injury and the offered coverage is of Rs. 7, 50,000 for third-party’s property damage.
NCB is provided to the policyholder and not to the insured automobile. At the time of the vehicle transfer, the insurance plan could be transferred to a new owner but NCB can’t be transferred. The responsibility of paying the remaining balance falls on the shoulders of the new buyer. The original/former owner of the vehicle can use the NCB at the time of purchase of a new automobile.
Insurance companies are changing their insurance rates all the time. Sometimes they raise them when there have been a large number of claims, and sometimes they lower rates when they are looking to pick up more clients. What all of this amounts to is that a cheap policy might just represent a market shift or a change in the needs of a particular company. In other words, don’t just give the hairy eyeball to all cheap rates; seek them out. Just make sure that the policy represents your needs well.
