No VIN no Title, can you register?

The short answer is "Yes". The State (NEV.) will inspect the vehicle to find its hidden VINs & if they locate it, run it. Assuming it's not stolen,your brother will have to contact the registered owner, request he sign over the car & that's it. Assuming the owner doesn't want to, the car is legally the registered owner's (or his estate) & he'll have to return it. If there's no VIN or the owner doesn't respond, usually within 30 days, your brother can apply for an abandoned title in his name & (again) he can register it. What if there's no VIN? The state can assign a VIN & allow it to be registered. It's not difficult, just alot of paper-chasing............
