Bill and Melinda Gates agreed how to divide their property and assets before announcing their divorce yesterday.
The billionaire couple, who have been married for 27 years, reportedly signed a separation contract outlining how their estate would be split.
But they did not sign a pre-nuptial agreement before their wedding in 1994.
The couple run the Bill & Melinda Gates Foundation, which has spent billions on charitable causes around the world.
They have pledged to continue to work together at the foundation once their divorce is finalised.
