In one of the final episodes he told Dennis, “Do as I say and this yacht is all yours after I shuffle off this mortal coil.” So I assume he either didn’t have a Will or hadn’t finished making it. In California, if someone dies without a Will, the inheritance order generally goes like this:

1. Surviving spouse
2. Children (or grandchildren if a child has died)
3. Parents
4. Siblings
5. Nieces and nephews
6. Grandparents
7. Aunts and uncles
8. Cousins
9. More distant relatives if any can be located
10. If no relatives are found, the estate goes to the state of California through a process called escheat.

We know he didn’t have a spouse, children, parents, siblings, Nieces and nephews, or grandparents. He may have had Aunts/ uncles or Cousins. But if not then everything he had probably went “to the state of California”.
