Who is the client?

VA notaries requires government issued ID with photo to be used for identification. However, the photo on the driver's license may be significantly different from the client due the age of the photo, health changes of the client or the client is not the client. Recently, I was confronted with this situation. I requested additional ID and was presented with Canadian passport and Green Card with photo. Clearly, the client was the client.
I notarized an elderly client in a nursing home. She had a non driver VA ID with photo but the photo was old. After viewing various other items I concluded the client was the client. Another option would have two persons with ID with photo that did not have an interest in the transaction swear that the client is the client. However, I think that should be rarely done
All VA notaries have absolute authority to refuse a notarization if they have concerns about the identity of the signer. I do not go to the Fairfax Adult Detention Center. I would be totally clueless on how to sort through multi-identities of some of the residents. The Fairfax Detention Center has notaries on staff who are more familiar with their clients than I am.
