(CNN) -- Russian oligarch Dmitry Rybolovlev is set to lose half his wealth after being ordered to pay his former wife $4.5 billion in a settlement dubbed the "most expensive divorce in history."
Elena Rybolovleva's lawyer Marc Bonnant said the order from a Geneva court was unprecedented, and "this record judgment is a complete victory."
However, Rybolovlev's spokesman Sergey Chernitsyn said the divorce was still a "win" for the oligarch. The two had been battling over the settlement for six years, after Elena Rybolovleva, the oligarch's wife of 23 years, filed for divorce.
