Is the property contract signed by the developer in the early stage always valid?

Legal analysis: First, the preliminary property entrustment contract is a contract signed by the developer and the property company. Entrust the property company to provide services for the pre-property, and at the same time, the property company shall sign a property management entrustment contract with the owner. Although the contract is signed by a real estate company and a property management company, it is equally binding on the owners and has no difference in legal effect. This has been clearly defined in property management laws and regulations. Therefore, if the owner does not pay the management fee, the property company can sue accordingly. 2. If the owner refuses to pay the upfront property fee, the basis for prosecution is: 1. Property management service contract signed with the owner (not stipulated in the contract). It is also a violation of contract law. 2. Property management regulations Article 42 The owner shall pay the property service fee in accordance with the provisions of the property service contract. If the owner and the user of the property agree that the user of the property shall pay the property service fee, the owner shall bear joint and several liability from the agreement. Three, the property has been completed but not yet sold or handed over to the property buyer, the property service fee paid by the construction unit.

Legal basis: Article 940th of the Civil Code of People's Republic of China (PRC). Before the expiration of the service period stipulated in the preliminary realty service contract concluded by the construction unit and the realty service provider according to law, the realty service contract concluded by the owners' committee or the owners and the new realty service provider takes effect and the preliminary realty service contract is terminated.
