Yes, you can sell your car. You have to take the buyer of your car to the bank and settle all your remaining amount in the bank plus pay you if the total price of the car beyond or higher than the remaining amount in the bank. After that process done, the bank will give out NOC to you for you to hand over the NOC to the new buyer for him to process with the traffic police department to change the ownership. You have to go along with the new buyer to the Insurance company to change the ownership before proceed to the traffic police department for changing the ownership and renewal of the registration card.
