MOSCOW, July 22 (RAPSI, Diana Gutsul) - Moscow's Presnensky District Court on Tuesday upheld a previous court decision to limit the right of Nickel CEO Vladimir Potanin’s former wife Natalya to control the alimony, Potanina’s attorney Phillip Ryabchenko told RAPSI.

The court thus rejected an appeal filed by Natalya Potanina.

Potanin has asked the court to limit the right of his former wife Natalya to control the alimony by transferring 50% of the monthly payments to his son’s account until he comes of age. Moscow's Presnensky District Magistrate Court granted the request in late June.

Vladimir Potanin and his wife divorced in February. Potanin who runs Russia's OAO GMK Norilsk Nickel has a reputation for philanthropy and endorsed Bill Gates’ and Warren Buffet’s “Giving Pledge” promising to give a significant portion of his net worth to the poor in undeveloped countries.

Natalya Potanina’s lawyers claim the billionaire’s charitable donations are only intended to hide his wealth estimated at $14.5 billion. Natalya is struggling to locate her husband’s assets so that she can obtain a court order for half of them, in accordance with the Russian law.
