The prohibition on notario público is absolute for a California notary who is not an attorney, and it is one of the few rules in notary practice with no cure available. The reason is that the term is not merely a translation. In civil law countries a notario público is a highly trained legal professional with authority to draft instruments and advise on legal matters, so a Spanish-speaking client encountering the term in the United States reasonably concludes they are dealing with a lawyer. That misunderstanding has been exploited repeatedly against immigrant communities, and the legislature's response was to remove the term entirely rather than to manage it through disclosure. So no posted notice cures it, spoken use is as prohibited as printed use, and the notary's own fluency in Spanish is beside the point — the problem is what the term conveys to the listener, not what the speaker intends. The related requirement, for notaries who advertise in a language other than English, is to post the statutory fee schedule and a notice that they are not an attorney.
