Legal analysis: 1. If it is clear that it is owned by one person alone, only one person is needed on the property certificate; There are two common situations: first, the house is one party's pre-marital property, and second, the real estate license clearly States that it is owned separately. 2. If the house bought during marriage, whether it is a person's name (no matter which one) or a person's name, is the same property, both husband and wife must sign it.

Legal basis: The establishment, alteration, transfer and extinction of the real right of immovable property in 208th of People's Republic of China (PRC) Civil Code shall be registered according to law. The establishment and transfer of the real right of movable property shall be delivered according to law.
