We must acknowledge the importance of highlighting the difference between a notrary public and a notario público on a terminological level. (There may be other options to translate "direccion nacional.")

“In jurisdictions where the civilian law prevails, such as in the countries of continental Europe, a notary public is a public official who serves as a public witness of facts transacted by private parties ... and also serves as impartiallegal advisor for the parties involved .... In colonial Louisiana, the notary public had the same rank and dignity as his continental civilian ancestor .... Although notaries still constitute a protected profession in present-day Louisiana, holding office for life provided they renew their bonds periodically in compliance with the governing statute, the importance of their function has diminished over the years to the point that it has been said that a Louisiana notary is no longer a truly civilian notary. Indeed, the trained lawyer is nowadays the Louisiana, and American, counterpart of the continental civilian notary.”
