Yeah but does he derive most of his wealth from his shares in MSFT and, if so, did he acquire those shares before marriage? AFAIK, the value of those shares is immaterial if he owned them outright before marriage. If he was drawing a salary during the marriage then half of it is hers, including any assets purchased with that salary, any gains on those assets, etc. Also, any inherited wealth coming from his parents should be his sole property. His dad died last year I believe but his widow(not Bill's mom) is still alive so the inheritance might not have happened yet.
