Bill and Melinda Gates filled for divorce after 27 years of marriage. It’s such a sad event that couple that managed to spend 27 years in marriage couldn’t be together.

This divorce is unexpected because they always seemed to be ideal couple. They worked together in philanthropy and managed to change lives of many people.

Bill and Melinda don’t have a prenuptial agreement and $140 billion family network might be split in half. If it will be split 50/50 than Melinda will became the richest women and this divorce will be the most expensive divorce in history.
