Property purchased during the marriage will be divided 50/50. However, Russian courts cannot divide property?

It is not clear to me whether money brought into the marriage by my wife, i.e. deposit on a house, has to be repaid by me. In the USA money brought into the marriage and used as a deposit for example, is considered as a gift and becomes joint property. Is Russian law the same?

If I have a child with a Russian girl I will be responsible for the child until 18. If I marry the Russian girl I will be responsible for Alimony until the child is age 3. (I should add that the Russian girl is not pregnant. I'm simply trying to get all the facts....)

Given that property cannot be divided by Russian courts, and should my wife move to the USA meaning Alimony will be decided in the USA – in your opinion is it in my best interests to get divorced in Russia or America? It appears to me that I will end up paying 2 times for lawyers, i.e. in the USA and Russia. Therefore, is it not better to simply get divorced in the USA...... My first assumption being that the divorce, alimony and financial agreements could be decided by Russian courts would be enforced in the UK and USA. This does not seem to be the case.

We both purchased properties in the UK prior to being married. They are not in joint names. I assume divorce proceeding in Russia do not take these properties into consideration?

My wife sold a property in England, and then we used this money to purchase a property in USA in joint names. Does Russian law insist any money invested into the marriage be returned? A mortgage was also used to finance this property based on my earnings.
We purchased a second property in the US in joint names. I am assuming this property will be divided equally?
I assume this money is divided equally?

Will I have to pay alimony to my wife once we are divorced? If so what is your best guess how much I will be liable for?
What is the shortest and what is the longest time I should expect a
divorce in Russia to take?
Will you be able to represent me?

Assuming my divorce is finalized in Russia satisfying Russian legislation, is my wife then able to take court action in the US if she finds alimony granted by the Russian courts is inadequate?

Assuming divorce proceeding press ahead and in the meantime I have a child with a Russian girl - how will this alter the divorce proceedings?

How would this impact Russian law - and in the second case how would this impact any subsequent action from a US court regarding alimony.
