Russian oligarch Roman Abramovich is worth $A11.75 billion — which makes him the 139th richest person in the world according to Forbes.

This month, he and wife Dasha Zhukova announced their plans to separate after ten years of marriage. The couple has two children, joint businesses in Russia, an extensive art collection, a mega-mansion on the Upper East Side, as well as other assests that could make this one of the most expensive splits in history.

Below, a look at the couple’s life.

Abramovich and Zhukova kept their marriage a secret for many years. The couple was often referred to as boyfriend and girlfriend after meeting in 2005. However in 2015, Zhukova revealed during a Wall Street Journal interview that the two had gotten married 'a few years' after meeting.

In 2010 Abramovich purchased his yacht, the $A319 million Eclipse, which is the third largest yacht in the world.

The boat played an integral role in the birth of the couple's second child, Leah Lou, in 2013. So that the child could be born in New York City, the boat stayed docked on the Hudson for two months, and Forbes estimated that the birth cost an estimated several hundred million.

But the divorce will still be expensive. While no numbers have been revealed yet, Abramovich's last divorce in 2007 to then-wife Irina cost him $A383 million -- and it was the second most expensive divorce in history.
