Then before you buy a house with a joint venture loan, you should sign a contract to prove that you two buy a house together. If you have this contract, everything will be settled. If you don't have this contract, only his name will be written on the household registration book, so there is no guarantee for you, and there is no legal guarantee for you. Everything is guaranteed, because it seems to have nothing to do with you, because it is written in the room book. You can't prove that you two are partners in a joint venture loan to buy a house, so you should sign a contract before buying a house to prove that you have a joint venture loan to buy a house and that * * * has contributed, which is your guarantee. I hope it's useful and helpful to you.
