First of all, the current requirements are unreasonable.

Because you didn't mention your husband's appearance or his current situation, I can only say that your current situation looks different from most people. My mother-in-law asked you to pay the mortgage together, but the house is not in your name, but in your father-in-law's name, which has nothing to do with you. To put it bluntly, if you can't reasonably prove that you are involved in the mortgage repayment, you have no chance at all in this house. Even if you can prove this, the house is your father-in-law's name after all, which is still a very difficult problem to solve. Besides, so is your car. You didn't say whether you bought it before marriage or after marriage, but I guess there is nothing to verify and it is unreasonable.

Second, there is suspicion that women are rich and men are beautiful.

Generally speaking, if the husband and wife jointly repay the loan, they can ask for an additional name, but you didn't say this option. I believe you can think of this choice. If you don't say it, it means you dare not. You can only say that you paid for it and let your husband write an IOU. Let me tell you: whether it has emotional influence or not, it is difficult to operate in legal practice. If the other spouse writes IOUs during marriage, it is difficult to operate in practice. What you should reflect on is: Why don't you dare to add your name? Why on earth did you marry him? There must be a reason, but you didn't tell the whole story. So in my opinion, your case seems to have some suspicion of Gao Fushuai.
