Whether and why the contract signed with the owner without property management qualification is valid, please seek the support of court precedent.

First of all, whether the unit or individual who has signed a contract with you without property management qualification has been authorized by the community owner or has certain management power in name, but it has not been reasonably proved by the management organization. Whether the signing is valid depends not so much on whether the will reached by both parties is reasonable and equal. If you think he is cheating, or fails to fulfill the requirements reached in advance by Shuangfa, then you can take legal measures. The final winning rate depends on your respective reasons and evidence. thank you
