What should I do if the cash property I bought in a small property right house at that time was not recognized by installments?

You can use the contract to appeal, and if the owner must approve it, you can also go through legal procedures.

The word "property" was translated from English property or estate, and was introduced into coastal areas and inland areas from Hong Kong, meaning property, assets, real estate, real estate, industry and so on. Since the word was introduced into China in 1980s, it has now formed a complete concept, that is, property refers to all kinds of houses and their supporting equipment, facilities and venues that have been built and put into use. Real estate can be large or small, a flat can be a real estate, and a building can also be used as a real estate. The same building can be divided into several real estates according to different ownership. Property includes a variety of formats, such as office buildings, commercial buildings, residential quarters, villas, industrial parks, hotels, factory warehouses and other property forms.
