Yes, but according to the law, you have to issue a power of attorney to the person you entrust, stating the entrusted matters and the scope of authorization.

Of course, in real life, you can also call the property. If the property does not accept this method, it can only be authorized by a power of attorney. Because, once there is a dispute in the future, the person who entrusts the signature is likely to deny that he entrusts others to sign.

In addition, when signing, you should indicate that someone signed it. Instead of writing the client's name directly.
