If I'm selling my car to another person using a private lien, who insures the vehicle?

The guy wants to make payments to me for my vehicle since he can't afford to pay me all at once. Who is supposed to insure the vehicle?

The buyer would have to insure the vehicle and list you as the "lien holder" on his insurance policy. This way, if the vehicle were to be totaled, you would receive compensation since you still have an ownership interest in the vehicle. You should also request a copy of the buyer's insurance declaration page for your own records.
