Have them send you the document - confirm all your commission info is correct and the same and it truly IS the document you notarized.
With this in hand, I don't see why you wouldn't be able to sign an affidavit stating that you performed that notarization. I would not re-notarize without the people in front of me - but you can sign an affidavit that you did - but ONLY IF they send you the document in question and all your commission info matches.
Good luck |
