Now that your house has been mortgaged, you can't add someone else's name unless the mortgage is lifted (you have to pay back the bank money).
But now you can withdraw your wife's provident fund to repay the bank loan.
The withdrawal amount depends on: 1. The balance in your wife's provident fund card.
2. Your annual commercial loan repayment amount.
Take a low value.
The information needed is loan contract, bank repayment flow, provident fund card, husband and wife ID card and marriage certificate.
