Can the owner refuse to pay the property fee because he has not signed a contract with the property company?

You can't. 1. The preliminary realty service contract signed by the construction unit and the service enterprise according to law, and the realty service contract signed by the owners' committee and the realty service enterprise selected by the owners' congress according to law are binding on the owners. 2. The owners' committee has not signed a property service contract with the property company, but the owners actually accept the property service, and the owners shall pay the corresponding fees to the property company according to the actual service price. Risk warning: the owner shall pay the property service fee according to 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. Property that has been completed but has not been sold or handed over to the property buyer shall be paid by the construction unit.
