Probably something that the insurance company initiated. Basically they sue, his and the companies insurance settles, and the family is out nothing out of pocket. That’s how pretty much any car accident here in the US works too. I’ve gotten personally sued for letting someone borrow my car who then got in an accident, for “I should have known she wasn’t a good driver” despite having a license and insurance herself. My insurance company settled and I paid nothing. That’s just how things are here unfortunately, if you don’t sue you may not collect the insurance money.
