If it so happened that you buy a car without knowing that it is stolen, then there is a high probability that you will have to sue its real owner. According to the lawyer, the court usually obliges to return the car to the owner. In order not to face such a major nuisance, again, you can check it on the traffic police website, or offer the seller to go together to the transport registration department and deregister it. He will probably refuse since he has no right to do so. For example, if you find an Isuzu n75 190 for sale and its seller is not giving you all the legal authentic information about it, then you must know that there is something fishy. What do you think?
