Jeff Bezos is currently listed as the world's richest person, with a stated net worth of $137B. This is almost exclusively from his partial ownership of Amazon, which was founded a year after his marriage to MacKenzie.
Jeff and MacKenzie live in Washington, a community property state. In community property states, both spouses are considered to jointly own all assets acquired after their marriage. Since Amazon was founded after they were married, it follows that all assets from Amazon are jointly owned.
Given that, why is Jeff alone considered to be worth $137B? Isn't it the case that Jeff and MacKenzie are collectively worth that amount?
Thus, do we say that Jeff is the richest person by convention or tradition only or is there a legal standing to that status, and he really does own those assets individually?
