Can the real estate license be used as evidence without official seal?

Property ownership certificate without official seal cannot be used as evidence.

This contract needs to be signed and sealed by both parties before it can take effect.

The official seal refers to the seal used by organs, organizations, enterprises and institutions. Because the Ministry of Public Security has not made uniform provisions on the engraving procedure, the provisions on the engraving procedure vary from place to place. According to the different types of seals, the procedures are different.
