Your liability for your brother-in-law's accident has nothing to do with his being on your policy. If you are the registered owner of the car he was driving, you can be sued, however, your liability as an owner of an involved vehicle is limited to $15,000 per person/$30,000 per accident. However, if you aren't the owner of his vehicle, you are not responsible for his accidents, even if he is on your insurance policy. Your insurance company might very well raise your rates, though, especially if your brother-in-law is found liable for an accident and the insurer has to pay damages to someone.
