Ok, let me analyze it for you from these two aspects.
First, first, my own rights and interests. I see that most other answers are also from this perspective, because husbands write their parents' names on real estate licenses differently under different circumstances. If the house is bought by the man's parents before marriage, it is reasonable for people to write their own names.
However, there are two payment methods for the elderly, one is lump sum payment, and the other is down payment. I don't think there is any problem if the old man pays in one lump sum before marriage and then writes his name. He can give you a room, but from their point of view, they are safer. After all, the elderly are also very insecure. He gave you all the money he worked hard for most of his life. In case you don't filial to them in the future, there is nothing wrong with it. This is not too much. If you only pay the down payment, you and your wife will have to pay back the next loan. Actually, it's ok to ask the name, but remember to leave a voucher for repayment, just in case something happens. However, if two people don't have much money at all and ask to write their own names, such parents are quite ignorant, and this situation is not acceptable.
The second question, emotionally. You may think, how can I prevent me from marrying my husband? You can tell whether the old man or your husband put forward the idea of writing your parents' names. If your husband put it forward, then I think it's time for you to have a good talk and see if there is trust between you. If it is proposed by an old man, the name of the money they gave is written on them, but in fact, if they give you a place to live, you will have an extra favor, whether for yourself or for the old man. If they don't have much money, they insist on writing his name and resolutely disagree, otherwise they can't stay in this family in the future.
In a word, nothing can't be solved by communication. The most fearful thing is to guess blindly, and then the more I think about it, the more excited I am, and the more I think about it, the more afraid I am.
