With a blind signer, you should proceed carefully because of the potential for fraud. A sightless person may have been misled about the contents of a document he or she cannot see or read.
You must determine whether the documents presented by blind clients are the ones they intend to sign. One way of doing this is to ask your client to explain the document’s purpose. If the signer is unsure of the purpose, you may have to read — but not explain — the document out loud.
Make sure you follow all other Notary best practices including positively identifying the signer through an identity document or a credible identifying witness; and screening for general awareness and willingness. As with any signer, if a visually impaired signer appears confused or unaware of what is going on, or if you suspect fraud, stop the notarization and note the circumstances in your journal.
