10. Roman and Irina Abramovich
Russian courts regularly honor the wife’s half of the riches developed amid the marriage, which in Abramovich’s situation, was his entire fortune. Irina settled for less in their 2007 split and got $300 million, which might seem like a ton, however, it was just 1.6% of his $18.7 billion fortune at the time.
Russian oil mogul Roman Abramovich was just a battling business person when he wedded Irina, who is his second wife, in 1991. His whole fortune was developed amid their marriage.
