I'm Lucy, and I'd be happy to answer your questions today.
If she has any reason to believe that it's not safe for her ex-husband to drive the car and she lets him drive it anyway, that could give her liability under negligent entrustment. Some of the most common examples of that are if a person is known to have been drinking when they take the car, has a drinking problem, or is known to be a bad or reckless driver.
Otherwise, her liability is limited to: $15,000 per person, $30,000 per accident, and $5,000 for damage to a third party's property. Their insurance policy
should provide coverage up to those limits. You can find those limitations in Cal. Veh. Code, Section 17151(a).
