If you present a notary with a document that is in a foreign language can he legally notarize it? He can if he is fluent in the language contained in that document.
In most cases, a notary can direct you to a certified translator or an attorney fluid in the language of the document. A notary cannot take the acknowledgment of a person who does not speak English or understand it. There is no prohibition against a person signing a document in a foreign language or symbols provided the document itself is composed entirely in the English language.
