According to the Family Law of the Russian Federation, private possessional and non-possessional rights and obligations of the spouses are defined by the law of the state, in which they live together. If they don't live together, then those right and responsibilities are defined by the law of the state in which they lived together for the last time. Any Russia-related private possessional and non-possessional rights and responsibilities of the spouses who have never lived together are defined by the law of the Russian Federation. I believe that Russian Court will not divide your property located outside the Russian Federation, especially since the last place where you were living together was in the US and not in the Russian Federation (hence it would be unlawful for the Russian Court to bring any judgment regarding property located in the US). I believe that you are aware that you can sign an agreement with your wife, which would define which property and in what amounts belongs to whom after the divorce. Maybe you can agree on conditions which will satisfy you both.

Regarding your wife's property in Moscow, it is important to know, when this property was acquired - before or after the marriage. Any property acquired before the marriage belongs to the spouse who acquired it. Any property acquired during marriage (with an exception of inheritance and free-of-charge transactions) typically is shared by the both spouses in equal parts, unless there is a prenuptial agreement, which says otherwise.

All the best to you,
