The property fee has not been paid. Can the real estate be stamped with the official seal? Is it legal?

This situation can be stamped with the official seal, which is legal.

If you don't pay the property fee, the property can be stamped with the official seal, but you can't charge. Chapter is the legal certificate of the property management company, which has legal effect and can collect property fees on behalf of the property management company. If the owner raises a defense on the grounds that he is not a party to the contract, the people's court will not support it. When the owner pays the property fee, he can pay it at the property service center and ask for a receipt as proof of payment.
