Ask the agency what they would accept as proof of representation. Some agencies might accept a notarized document, others might accept a hand written letter with a phone number so they can contact the owner and obtain some further details of their identity.
The agency should be able to tell you what would be acceptable.
I have accepted hand written letters and even simple phone calls from owners when I could verify the identity of the person writing the letter or doing the calling. This agency's requirements may be more stringent.
