Final answer:
To notarize an acknowledgment on a document that has been signed before the notary arrives, the notary can still proceed with the notarization process if the signer is present and provides identification.
Step-by-step explanation:
To notarize an acknowledgment on a document that has been signed before the notary arrives, you will need to follow the proper procedures. Typically, the notary will need to witness the signing of the document. However, in this case, the notary can still notarize the acknowledgment as long as the signer is present and provides satisfactory identification. The notary will need to confirm that the signature on the document matches the signer's identification and then proceed with the notarization process. It is important to note that notarizing an acknowledgment is different from notarizing a signature.
