Ex-Wife of Sanctioned Russian Tycoon Wins Divorce Appeal in London

The ex-wife of sanctioned former Russian Prime Minister Vladimir Potanin has successfully appealed a divorce ruling, allowing her to pursue a multi-billion-pound financial settlement in England. Natalia Nikolaevna Potanina won her case at the Court of Appeal, challenging the adequacy of a previous financial relief order issued by a Russian court.

Potanina and Potanin were married for approximately thirty years before their divorce in Russia in 2014. Following the divorce, she contended that the Russian court’s financial settlement left her with a “paltry” amount, especially when compared to her ex-husband’s considerable wealth. Potanin, identified as one of the wealthiest individuals in Russia, is the founder of the major management company Interros and has held significant governmental roles, including serving as the country’s first deputy prime minister from 1996 to 1997. His business and political ties have placed him under sanctions from countries including Ukraine, the United Kingdom, the United States, Canada, Australia, and New Zealand.

Potanina initially filed her case in the English High Court in early 2019 under the Matrimonial and Family Proceedings Act 1984, taking advantage of her residency in England since January 2016. The case has seen a tumultuous legal history, beginning with a grant of leave without Potanin’s notice. Potanin subsequently sought to have this grant overturned. In November 2019, Mr. Justice Cohen granted his request, dismissing Potanina’s renewed application.

The legal battle continued when Potanina appealed to the Court of Appeal in 2021, which reinstated her application. However, in 2024, Potanin successfully appealed to the Supreme Court, leading to the remittance of the case back to the Court of Appeal for further consideration. The most recent hearing took place in July, culminating in today’s decision by the Court of Appeal to approve Potanina’s appeal, granting her the right to pursue her claims in England.

Frances Hughes, a partner at Hughes Fowler Carruthers who represents Potanina, stated, “The decision of the Court of Appeal is a second vindication of our client in making her application in 2019.” She expressed gratitude for the court’s consideration and emphasized Potanina’s hope for a swift resolution to her case.

Legal experts have noted the potential implications of this ruling. Sarah Jane Lenihan, a partner at Dawson Cornwell, remarked that “few expected this outcome,” suggesting that it could open pathways for others who have divorced overseas to seek legal recourse in England. Additionally, Hayley Trim, a partner at Irwin Mitchell, referred to the ruling as a “landmark decision” that underscores the importance of English courts in international divorce matters.

As this case progresses, it not only highlights the complexities of high-net-worth divorces but also raises questions about jurisdiction in international family law. The outcome may set a precedent for future cases involving individuals with significant financial disputes across borders.
