Thus, the marriage contract is broader in content than the agreement on division of property, and also allows you to establish the regime of ownership of the property that is only planned to be acquired (for example, if at the moment the spouses have opened accounts only in one bank, but the spouses understand that in the future may open accounts in other banks, including foreign ones, the marriage contract allows to describe this situation, using common wording, which allows to protect the interests of the spouses. In the case of a property settlement agreement, the accounts would need to be clearly named). The key difference between these tools is the fact that only a property sharing agreement can be entered into after the marriage is dissolved.
Please note that in case of an property sharing agreement after dissolution of marriage, the amount paid by the ex-spouse who received a larger share of property to the ex-spouse who received a smaller share of property, based on the property sharing agreement, is income subject to personal income tax (Letter of the Federal Tax Service of Russia dated 15.03.2017 N BS-4-11/4624 "On taxation of compensation upon dissolution of marriage" (together with Letter of the Ministry of Finance of Russia dated 02.03.2017 N 03-04-07/11811))
