Bill and Melinda Gates ($73 billion)
After 27 years of marriage, the generous couple announced their shocking divorce on May 3, 2021. According to court filings, the two had a private separation agreement but no prenuptial agreement in place — and because they spent so much of their working life together, untangling their assets might be difficult.
They own multiple homes, including a $130.88 million waterfront property in Medina, Washington, and a $43 million home in Del Mar, California. Forbes assessed Bill's net worth to be $130.5 billion.
The pair is the founders of the Bill and Melinda Gates Foundation, one of the world's most influential non-profit organisations, which spends $5 billion each year battling poverty, sickness, and inequality worldwide. Mrs Gates is projected to be worth $73 billion if they split their assets evenly, making the divorce the most costly in history.
