How to add the name of the other party to the house bought by the husband and wife through provident fund loans after marriage?

Do not add this. If you want to add, you must bind two people's provident fund accounts, which means you have lost a chance to buy a house. Although you may not buy it, it is always good to keep it. And the new civil code stipulates that as long as you repay the loan together, the house is still the property of husband and wife, and it doesn't make sense to add or not.
