Billionaire Dmitry Rybolovlev, Russia's 14th-richest person, and his wife, Elena Rybolovleva, have been brawling for almost five years in at least seven countries over his $9.5 billion fortune. In a divorce complaint originated in Geneva in 2008, Rybolovleva accused her husband of using a multitude of third parties" to create a network of offshore holding companies and trusts to place assets -- including about $500 million in art, $36 million in jewelry and an $80 million yacht -- beyond her reach. She has brought legal action against the 48-year-old Rybolovlev in the British Virgin Islands, England, Wales, the U.S., Cyprus, Singapore and Switzerland, and is seeking $6 billion. The suits provide a window into the offshore structures and secrecy jurisdictions the world's richest people use to manage, preserve and conceal their assets. According to Tax Justice Network, a U.K.-based organization that campaigns for transparency in the financial system, wealthy individuals were hiding as much as $32 trillion offshore at the end of 2010. Fewer than 100,000 people own $9.8 trillion of offshore assets. More than 30 percent of the world's 200 richest people, who have a $2.8 trillion collective net worth ...control part of their personal fortune through an offshore holding company or other domestic entity where the assets are held indirectly. These structures often hide assets from tax authorities or provide legal protection from government seizure and lawsuits.
