I did the legal work to incorporate a business and am now acting for that business on another matter. May I rely on documents already in my possession to verify the client’s identity or must I rely on documents from a government registry?
As long as the documents are current and qualify as written confirmation from a government registry as to the existence of the corporation, relying on documents in your possession is fine. The documents referred to in the rule are examples of independent, reliable documents, but the list is not exhaustive. As you incorporated the business, you likely have a copy of the certificate of incorporation, which is an acceptable source.
