Is there a property company name on the purchase contract?

In the process of the owner's purchase and residence, the main parties involved are: the owner (purchaser), the developer and the property management company. The existing legal relationships are: the pre-occupancy and property handover management relationship between the property management company and the developer, the legal relationship between the owner and the developer on the sale and maintenance of the house, the legal relationship between the owner and the property management company, the adjacent legal relationship between the owners and other legal relationships arising from infringement. Although there may be multiple legal relationships in the same subject, such as the owner is also the purchaser, the legal relationship with the property management company, the legal relationship with the developer, the neighboring relationship with other owners, etc., it should be clear that these legal relationships are mutual, so the rights and obligations of the subject cannot be confused.
