How to prove the owner of a small property right house

Legal analysis: the state implements the system of registration and certification of house ownership, and the certificate of house ownership is the only legal basis for the right holder to own the house according to law and exercise the right of possession, use, income and disposal of the house.

Legal basis: Article 2 17 of the Civil Code of People's Republic of China (PRC) stipulates that the obligee enjoys the real right of immovable property. If the items recorded in the real estate ownership certificate are inconsistent with those recorded in the real estate register, the real estate register shall prevail unless there is evidence to prove that there is an error in the real estate register.
