In 2014, Russia's Richest Man Divorced His Wife Of 30 Years. He Paid Her $6.4 Million Thanks To A "Backdating" Trick. Now She Wants $5 Billion

In 2014, Russian businessman Vladimir Potanin finalized his divorce from his wife of more than 30 years, Natalia Potanina. The couple had been married since 1983 and built their life, and much of his empire, during one of the most chaotic and lucrative periods in modern economic history: the collapse of the Soviet Union and the rise of Russia's oligarch class. Together, they had three children.

When the marriage ended, a Russian court awarded Natalia approximately $6.4 million.

For the overwhelming majority of people on the planet, a $6.4 million divorce settlement would be a life-changing outcome. It would represent a lifetime of financial security and a clean break. But these were not ordinary circumstances, and this was not an ordinary fortune.

If you exclude Vladimir Putin's alleged $100-200 billion secret hidden fortune, for much of the last 10 years, Vladimir Potanin has been the richest person in Russia, including at this moment! By our estimation, Potanin's current $30 billion net worth makes him the #1 richest person in Russia.

So why did Natalia only get $6.4 million? Was Vladimir not a billionaire yet? Nope! In the years leading up to their divorce, his net worth ranged from $10 to $14 billion.

The Marriage, The Fortune, And The Breakup

Vladimir and Natalia Potanina met as students in Moscow and married in 1983. Vladimir was on a conventional path, following his father into work connected to the Soviet foreign trade system. Within a decade, that system would collapse, creating one of the most chaotic wealth transfers in modern history.

Like a small group of well-connected and highly opportunistic businessmen, Vladimir was perfectly positioned to take advantage. In the early 1990s, he co-founded one of Russia's first private banks alongside Mikhail Prokhorov. Through the controversial "loans-for-shares" privatization program, the pair acquired major stakes in some of the country's most valuable industrial assets. The crown jewel was Norilsk Nickel, a massive metals company that would go on to generate billions in revenue and become the backbone of Potanin's fortune.

Over the next decade, Norilsk Nickel expanded at a staggering pace. Revenues surged into the billions, profits climbed sharply, and when the company eventually went public, Potanin and Prokhorov became among the richest men in Russia almost overnight.

The partnership between Potanin and Prokhorov ultimately unraveled in dramatic fashion. In early 2007, Prokhorov flew to the French resort town of Courchevel on a private jet to celebrate the New Year. According to French authorities, the trip included a group of Russian prostitutes who had been flown in to accompany him and his friends. After several days of partying, French police raided the resort and detained Prokhorov and others as part of an investigation into organized prostitution.

The scandal made international headlines and caused a major backlash in Russia. Prokhorov was forced to sell his share in the business for $10 billion IN CASH. Prokhorov went on to buy the New Jersey Nets with Jay-Z. Meanwhile, Potanin was firmly in control of Norilsk Nickel and the broader network of assets that would define his fortune for the next decade.

Throughout all of it, Natalia was his wife. She raised their three children and lived alongside him as his wealth was created, expanded, lost, and rebuilt.

By the time their marriage unraveled, virtually all of Potanin's fortune had been built during their 30 years together.

The end came suddenly.

A Tricky Divorce Move

In November 2013, after nearly three decades of marriage, Vladimir informed Natalia that he wanted a divorce. According to her later accounts, the conversation came without warning, following what had appeared to be a completely normal family evening.

Compounding the shock was a critical detail: Potanin sought to backdate the effective end of the marriage to 2007. That date was not arbitrary. It came just before the final unwinding of his business partnership with Prokhorov and before a significant portion of his modern fortune fully took shape.

Around the same time, it emerged that he had been in a relationship with a younger employee and had fathered a child with her. He would go on to marry her in 2014, shortly after the divorce was finalized.

The $6.4 Million Settlement That Sparked A Decade-Long Fight

When the case moved through the Russian court system, the outcome was strikingly lopsided.

Despite Potanin's vast wealth, Natalia was awarded approximately $6.4 million. Her claims to a share of his most valuable assets, including stakes tied to Norilsk Nickel and Interros, were rejected. The court also accepted the earlier termination date of the marriage, significantly limiting what was considered jointly accumulated wealth.

From Natalia's perspective, the result bore little resemblance to a fair division of a 30-year partnership. Her legal team later argued that the settlement represented roughly 1% of the couple's total marital assets.

Potanin, for his part, maintained that his personal income was far more limited than outsiders assumed, and that much of the wealth attributed to him was held within complex corporate structures rather than directly owned.

Whatever the technical arguments, the practical outcome was clear. A woman who had spent three decades married to one of the richest men in Russia walked away with a fraction of what most observers would have expected.

For many people, that might have been the end of the story.

For Natalia Potanina, it was the beginning of a much larger fight.

Taking The Fight Outside Russia

After losing in Russian courts, Natalia took the fight abroad.

In 2018, she filed a new claim in London seeking a far larger share of the fortune she says was built during their 30-year marriage. By then a UK citizen, she had a legal pathway to pursue the case in a jurisdiction known for more aggressive division of marital wealth.

The stakes jumped from millions to billions, with her claim reportedly reaching as high as $5 billion.

For Potanin, it opened a far more complicated legal battle.

A Decade-Long Legal War

The case has dragged on for years with no resolution.

Potanin has challenged the authority of UK courts, arguing the divorce was already settled in Russia. Natalia has countered that the original ruling failed to reflect the true scale of their shared assets.

Just this week, the long-running legal battle took a meaningful step forward.

A London judge rejected Vladimir Potanin's attempt to delay the proceedings, clearing the way for the case to move closer to a final hearing. The court cited an "urgent need" to resolve the dispute, noting that roughly £14 million (about $18.9 million) has already been spent by both sides on legal fees alone.

A full hearing is now expected later this year, where Natalia will continue her push for a multibillion-dollar settlement.

Even as the case advances, the central challenge remains the same. Potanin is now a sanctioned oligarch, and his legal team has argued that the vast majority of his wealth has been relocated inside Russia. Furthermore, Potanin is currently pushing Moscow courts to issue an injunction that could hit Natalia with massive financial penalties simply for continuing her case in London. And for some reason, I have a strong hunch that the Moscow court will rule in his favor.

The UK court may ultimately determine that Natalia is owed billions. But turning a London judge's order into actual cash from a sanctioned Russian oligarch's fortress could prove to be the hardest fight of all.
