The most expensive divorce in history may soon become the most expensive divorce reduction in history.

Earlier this month, a Swiss appeals court slashed nearly $4 billion from the award that Russian billionaire Dmitry Rybolovlev was ordered to pay his ex-wife, Elena Rybolovleva, in their divorce. The court ruled that the judgment of 4 billion Swiss francs (around $4.4 billion) awarded last year to Rybolovleva should instead be capped at 564 million Swiss francs, or around $600 million.
