1. How can one buy a vintage car which does not have papers and the ownership cannot be proven. Generally they are found in villages or someone's home with no papers showing ownership.
If there are no proper documents or RC book or any other details, it will be very unsafe to buy such cars because it cannot be run on road owing to many faults, ex., it is not known when and what are all taxes due to be paid, insurance, involvement n accidents earlier or in any criminal matter etc. So never make the mistake of buying it if the name of the previous owner cannot be ascertained.
Person's grandfather owned a vintage car, but died without any mention of the car in the will etc. Then father of the person also died but did not mention the car in the will and divided the ancestrial property between two sons and all other items to go to one son only, who is mentioned in the will. In this case will the vintage car also go to the brother who has been mentioned in the will saying all other things go to him.
Whether the number plate is available?, check for the Registration number of the car: Check for the state of registration. You can get the details from the RTO office giving information about RC number.
As per will let the car also go to the same person, but how will you confirm the owner of the car, the person who bequeathed the car cannot sell it as an owner.
