MOSCOW, September 18 - RAPSI. Former Russian Senator Vladimir Slutsker has filed an appeal challenging a London court decision that granted ownership of his $65 million London mansion to his ex-wife, Slutkser's press secretary Yekaterina Shatalina told RAPSI Tuesday.

"Thus, the High Court of Justice's ruling has not come into effect," she said. "The mansion will be under arrest until the appellate instance, comprising a three-judge panel, issues a decision. It will be final."

The court said Olga Slutsker has paid to refurbish the mansion using her own income from a chain of her fitness clubs. She also owned the house on a constructive trust basis under agreements reached with her husband.

It was earlier reported that Olga Slutsker has also managed to retain custody of their children. The Moscow Presnensky District Court previously passed a decision to divide the couple's jointly acquired property, partially satisfying Vladimir and Olga Slutsker's lawsuits. The court divided a collection of paintings between them assessed at $30 million. Olga Slutsker's attorney was determined to appeal the decision.
