(Adds Uralkali comment)
MOSCOW, July 7 The wife of Russian billionaire Dmitry Rybolovlev, owner of a Russian fertiliser firm worth $7 billion, has filed for divorce and division of property, including a $100 million Palm Beach villa, the Palm Beach Post said.
Rybolovlev, 41, made his fortune from potash mines in the Ural mountains and controls Uralkali (URKA.MM), whose Belarus-based export agent is the world's biggest potash exporter.
"In the event that management becomes aware of information regarding it that it believes is price sensitive to the company's equity securities, we will notify the market accordingly," Uralkali spokeswoman Larissa Belyayeva said in emailed remarks. She declined to comment on the divorce suit.
The newspaper said Yelena Rybolovleva has filed a lawsuit in Switzerland. The Palm Beach County Clerk and Comptroller's website also has a notice of lis pendens to Dmitry Rybolovlev filed by Yelena Rybolovleva in December 2008.
Rybolovlev is ranked 59th by Forbes magazine on a list of the world's billionaires, with an estimated net worth of $12.8 billion.
Rybolovlev paid $100 million to U.S. property tycoon Donald Trump for the waterfront property in 2008 in what was seen at the time as the biggest single family home sale in U.S. history. (Writing by Gleb Bryanski and Melissa Akin; Editing by Greg Mahlich)
