According to Chinese law, you don't need your spouse's signature to buy a house. But pay attention to the following points:

1. If the house belongs to both husband and wife, both husband and wife need to sign it when selling the house.

2. If the house is personal property, the signature of the spouse is not required to sell the house. No matter the name of one party or the names of both parties on the real estate license, as long as the property right of the house acquired by the husband and wife with the same investment (including loans) after marriage is the same property.
