Then, if you want to add a name, you need to repay the loan. There is no loan at home, and two people go to the Housing Authority with their ID cards, marriage certificates and real estate licenses. Marriage certificate and name only need a handling fee of 100 yuan. If there is no marriage certificate, you need to pay taxes in proportion. Forget the percentage. Anyway, a set of 90 flats costs about 30 thousand.
If it is notarized, it is best to write clearly that the down payment of the house is borne by the woman's mother and the woman is also responsible for repaying the loan. What is the share when repaying the loan? If you can discuss the percentage of house ownership, please indicate it when notarization.
If there is no prescribed proportion and your name is added, your mother's down payment is notarized. The division determined by the court is that your boyfriend can only get his share of the loan repayment, and both the down payment and your share of the loan repayment belong to the woman.
