May a notary give legal advice or draft legal documents?

No. Unless the notary also is an attorney, the notary cannot act as a legal advisor and cannot prepare legal documents. For example, if a document does not contain a notarial certificate, the notary public cannot advise as to the proper type of notarization. an attorney should be consulted as to the proper notarization that is required for the document (acknowledgment, witnessing or verification).
