Lawyer Song Li suggested: First of all, if you want to buy a house with a loan in the name of your child, you'd better do it before your child gets married. Children facing marriage can apply for signing a notarization agreement with their parents before marriage to notarize the share of capital contribution, monthly repayment and house ownership. Second, when buying a house, the old couple should also sign their names on the purchase contract and real estate license, not just the names of their children. Because multiple names can appear on the purchase contract and real estate license, only the child's name must appear. When paying down payment and monthly payment, don't use cash, but use bank transfer and keep relevant vouchers.
