It could have been seen that way and done something about it before it was sold, in my opinion.
Of course, some would argue it's still community's property, and if Sun doesn't like it, he should go to Ned and ask for his money back.
But here's when written contracts are more powerful than "understandings". Do you think he will do that? Should he do that? Do we want him to do that?
Or we just wanted him at the table in a negotiation where he will say anything we want to hear in order to see his stake released?
