7. Dmitry Rybolovlev and Elena Rybolovlev, 2014 — $604 million

Elena Rybolovleva filed for divorce from Russian businessman Dmitry Rybolovlev and cited his "serial infidelity," saying he used to "share his young conquests with his friends, and other oligarchs."

The courts initially awarded Elena a whopping $4.5 billion in the settlement in 2014, but after an appeal, she walked away with "only" $604 million.
