I have Suzuki Cultus. The person from whom I bought this car told me that the file was missing, and the car was being sold without the file. At that time, I didn't know the consequences of buying a car without the file. Now, when I want to sell the car, I tried to trace the first owner, but I couldn't find him because he was from Karachi. I don't have his CNIC, ID card number, or phone number. The only thing I have is the car's book, which mentions his name and address. When we tried to trace the address in Karachi, we found out that there is no such colony or area by that name. I want to know that the car is registered in Lahore, and I want to get a duplicate file for the car. But the first owner, whose name the car is in, cannot be traced. What is the procedure through which I can get the file for the car?
