A RUSSIAN oligarch’s estranged wife has won a six-year fight to drag her divorce battle into the English courts.
Natalia Potanina secured a landmark of Appeal ruling on Thursday to sue her billionaire ex-husband Vladimir Potanin, who is said to be worth around £15.7billion.

Potanin is described as Russia’s second richest man and a pal of through their shared love of ice .
Potanin is the chief executive of Norilsk Nickel, the world’s largest palladium producer and a global nickel giant.
But he was sanctioned by the UK and US in 2022 after Putin’s brutal .
The former couple wed in in 1983, where they lived for their entire married life and raised three children.
They split in acrimonious fashion, with Potanin claiming the ended in 2007.
Potanina insists they only separated in 2013, with a Russian court finalising the a year later.
Potanina has previously claimed their marriage ended when her husband calmly told her over tea that he was
She said at first she thought it was a “badly-worded joke” but was later told she “didn’t need money” when the subject of a financial settlement arose.
The pair first met as penniless students in the 1970s, when was still under communism.
Potanina argues that her husband only built his fortune after their marriage, and that she supported him throughout his rise.
Despite his £15billion fortune, Potanina was awarded just £30.9million in the Russian – less than one per cent of the family wealth.
Lawyers for Potanin argue she actually received around £63m, but she insists the sum barely scratched the surface of their assets.
Now, after years of legal wrangling, Potanina has been cleared to bring a claim in for financial relief – setting the stage for what could become the world’s biggest-ever marital split.
She is seeking half of her ex-husband’s beneficial interest in shares in Norilsk Nickel, along with half of the dividends paid on those shares since 2014.
She also wants half the value of a lavish mansion known as The Autumn House, on which the couple splashed out around £111million.
She is thought to be seeking around £5billion in total.
At the heart of earlier disputes was the couple’s palatial family home in Nemchinovo, 17 miles west of Moscow, where they lived with their three children – daughter Anastasia, and sons Ivan and Vasily.
Also up for grabs were two superyachts, including “The Anastasia,” named after their daughter, and “The Nirvana.”
Potanina’s legal team told the court she had earned her share of the fortune through years of marriage and by being the “main carer” of their children.
Her barrister, Charles Howard KC, branded the earlier dismissal of her case “inconsistent and illogical,” accusing the judge of falling into Potanin’s trap of repeatedly labelling her a “divorce tourist.”
Potanin’s lawyers, led by Lord Faulks KC, countered that the couple had “no connection with this jurisdiction during the marriage” and that Potanina only had “recent and modest connections” to when she applied.
London’s High Court originally threw out her claim in 2019, warning that allowing it would mean “no limit to divorce tourism.”
That decision was overturned in 2021 by the , only for Potanin to win a narrow 3-2 victory in the last year, which sent the case back to be reconsidered.
Now, judges Lord Justice Moylan, Lady Justice Falk and Lord Justice Cobb have sided with Potanina once again, ruling she had “substantial grounds” to pursue her claim in .

They said there was evidence she had “very largely severed her ties with Russia” and that her connection to the country was “increasingly tenuous.”
The ruling added: “The discrepancy between her award of the marital assets and the husband’s retained share was significant.
“The discrepancy between what she had recovered in compared with what she would have recovered had the case been heard in this jurisdiction was equally significant.”
The Sun reported in 2016 that Potanina was near Westminster Abbey.
She said at the time to be fearing that if she returned to Russia her passport could be seized, preventing her from visiting her son studying in .
She also accused her husband of offering her only medical , a driver, and maintenance for their youngest child, rather than a fair settlement.
The blockbuster ruling reignites fears that will become the “divorce capital of the world.”
Jennifer Headon, head of international family at Birketts LLP, said the High Court had already warned such a move could open the floodgates to “limitless” divorce tourism.
Sarah Jane Lenihan, partner at Dawson Cornwell, said few had expected such an outcome, asking: “The question now is whether it will open the door for others who have divorced overseas to seek a second bite at the cherry in England.”
Sital Fontenelle, head of family law at Kingsley Napley LLP, said the ruling reinforced the UK’s status as the “divorce capital of the world” and left the “door still open” for future claims.
Peter Burgess, partner at Burgess Mee, added that aspiring “divorce tourists” might now wait to demonstrate their links to England at a full hearing rather than being knocked back early.
She has previously said her situation reflects the discrimination faced by many women in Russia, where “the law is male, the ideology is male,” adding that she had been “deprived of and driven out of the house.”
Potanina’s solicitor, Frances Hughes of Hughes Fowler Carruthers, hailed the ruling as a “second vindication” of her client’s case, saying Potanina was delighted and now hoped the matter could be “resolved without further delay.”
