Jeff Bezos , founder and CEO of Amazon, andwife MacKenzie Bezos announced they've finalized the terms of their divorce after 25 years of marriage.

Jeff Bezos founded Amazon after he and MacKenzie Bezos got married , Business Insider's Shana Lebowitz reported. In the community property state of Washington, which dictates assets acquired during marriage to be split 50-50, that means MacKenzie Bezos could have a right to half of her husband's Amazon fortune if they didn't sign a prenup (which they reportedly didn't).

That could leave a wife divorcing the world's richest man who has an estimated net worth of nearly $150 billion as the world's richest woman; but that's not quite the case for Mackenzie Bezos.
