In what may be the “most expensive divorce in history,” Dmitry Rybolovlev will be ordered to pay his ex-wife $4.5 billion. Known as the “fertilizer king” for heading a $34 billion fertilizer company, the Russian oligarch was quite open with his philandering for years, even with his wife, Elena. She appeared to hit her limit and launched a financially messy divorce battle against him a few years ago, including having his assets frozen in 2013. Because many billionaires do not publicize their divorce settlements, it cannot be determined if Rybolovlev’s is officially the most expensive in history. However, as a point of comparison, Rupert Murdoch’s cost him $1.7 billion—pocket change compared to this tainted love.
