Russia’s Richest Man Faces One of the Most Expensive Divorces in History

The Court of Appeal ruled Mrs. Potanina can pursue a claim for half of her ex-husband's $20 billion fortune, potentially creating one of England's largest divorce settlements.

  • On Thursday, the Court of Appeal allowed Natalia Potanina to pursue a multibillion-pound divorce claim against her ex-husband Vladimir Potanin in London.
  • This decision comes after several years of litigation, beginning with Mr Justice Cohen’s 2019 dismissal of the case, which the Court of Appeal reversed in 2021, allowing the proceedings to move forward despite sanctions imposed on Potanin.
  • Potanina seeks half of Potanin's shares in Norilsk Nickel, dividends since 2014, and a high-end Russian property, arguing she supported his rise during their 31-year marriage.
  • The claim is valued around £5 billion , potentially becoming one of the world's largest divorces, while Potanin's fortune is estimated near $20 billion and he remains sanctioned for supporting the Kremlin.
  • Potanina hopes the matter resolves without delay, with legal experts noting London’s status as a major divorce jurisdiction and that this decision encourages fair outcomes for wealthy spouses.
