I bought a car at auction and had it towed to my home and parked. While it was parked, uninsured and unregistered, my brother got the keys and drove it. He hit somebody, but didn't tell me.
I just got a letter from the other driver's insurance company demanding compensation for the damage to their customer's car. I don't think I should have to pay anything because I wasn't driving the car and it was taken without my permission. What should I do? We're in California.
