Relax, not a big problem. and keep the car. Now here is what you need to do.
- Get FIR for document loss
- keep original ID of owner handy
- any other relevant document for car should help
- News paper AD for papers lost.
then simply contact some agent in Civic center. I think with all this stuff handy, you can get a new book transfered to your name in 10,000 Max. thats the rough idea, if you are smart then you can negotiate and get a better bargain and remember, its do able not impossible.
