Can the owner refuse to pay the property management fee on the grounds that the property management contract has not been signed?

You can't. According to the property management regulations, if the owners' committee signs a property management contract with the property management company, the owners shall be bound by it and have the obligation to pay the property fee. If the owners' committee has not signed a property service contract with the property company, but the owners have actually accepted the property service, the owners shall pay the corresponding fees to the property company according to the actual service price.

According to the property management regulations:

Article 41

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.
