If it is bought after marriage, even if there is only one person's name, it is also the property of your husband and wife and should be divided equally.
However, whether bought before marriage or after marriage, if the loan is repaid together, the part of the loan repaid after marriage and the value-added part should be equally divided.
Specific calculation method:
* * * Use the total repayment amount (principal and interest) ÷ the total purchase price (down payment+total mortgage loan principal+total loan interest) to calculate the ratio of the total repayment amount to the total purchase price.
Then use the present value of the house × ratio to calculate the amount of * * and the total payment for repayment of the loan in the present value of the house. (including the value-added part) and then use this amount to calculate the value-added and full compensation of the repayment part of one party.
