Yes, but according to legal provisions, you should issue a power of attorney to the person entrusted by you, indicating the matters entrusted and the scope of authorization.
Of course, in real life, you can also notify the property owner by calling. If the property does not accept this method, it can only be authorized through a power of attorney. Because, if there is a dispute in the future, the person who is entrusted to sign is likely to deny that he has ever entrusted someone else to sign.
In addition, when signing, it should be stated: signed by so-and-so. Instead of writing the name of the person involved directly.
