Notarizing a document with blank spaces can lead to fraud, so the notary should refuse to notarize it until all blanks are filled in or crossed out.
A notary must ensure they understand the document being notarized, especially if it’s in a foreign language, to avoid notarizing something that may be illegal or unethical.
