A very significant portion of my practice is drafting wills for folks who have quite a lot--and no, sadly, it does not surprise me--either that advisors didn't suggest it, or if they did, that he didn't listen.
It's unfortunate for many reasons, not the least of which is the fact that is the chief method in almost every state by which an individual can name a guardian of his or her minor children, to take effect upon death. His mother has petitioned, and received (at least temporarily) custodianship of his kids; who knows if that bears any resemblance to the result he would have wanted.
Chuck has it right--this will be tied up in trust & estate litigation for years--something I take it upon myself to do everything in my power to avoid. The lawyers will be the winners, I fear.
I heard on the radio today that nobody is sure if he had a will.
Can you imagine someone that wealthy whose financial advisors did not insist that he have a will?
I can imagine someone that wealthy not listening to those advisors had they suggested he make a will.
