What is the purpose of having the document notarized? In many cases the main reason for having a document notarized is for acknowledgment purposes (signature verification). If you are requiring the notary to make the fraud victim sign the documentation under oath by being sworn in by the notary, you will need to check on the state law requirements. For example, the Commonwealth of Kentucky does not require the used of a notary seal but Indiana does. It is a state by state matter in reference to the notary but I believe you are making it harder for the customer to notify you that they are a victim of fraud and could put your institution as risk, whether legal or reputation.
