Overview

• Natalia Potanina won permission to seek 50% of Vladimir Potanin’s ultimate beneficial interest in Nornickel shares, 50% of dividends since 2014, and a luxury Russian property said to have cost about $150 million.
• The Court of Appeal overturned a 2019 High Court refusal after a rehearing ordered by the Supreme Court, clearing the case to proceed in England following a July hearing.
• Judges noted evidence that Potanina has largely severed links with Russia and highlighted the significant gap between her Russian award and what could have been awarded under English law.
• Potanina’s lawyers say she received $41.5 million in Russia, while Potanin maintains the figure was about $84 million and disputes any meaningful British connection.
• The litigation could become one of the highest‑value matrimonial cases in England as Potanin, chief executive of Nornickel, faces claims tied to his stake in the major metals producer.
