He’d been homeless and on Sunday night checked into an average hotel, so I doubt he’s currently rich enough to pay this lawyer.
Assuming Rob and Michelle named Nick in their wills, I just read that Nick will find himself ineligible to inherit because of the California law called ‘slayer statue’ so if you murder someone you’re due to inherit from and you’re convicted and sane, you don’t get a penny from the estate. But if he’s found not guilty due to insanity then he could be allowed to inherit, which his lawyer will be well aware of, of course.
