SITUATION: A signer comes to you requesting that you perform a jurat notarization. When you ask him for identification, he hands you a "matricula consular" card, an identification document issued by Mexican consulates to Mexican nationals outside their country. You have never seen the card before and can't seem to find anything about it in your state Notary statutes or handbook.
Is this an acceptable form of identification when identifying someone for a notarization?
ANSWER: In general, no. While the matricula consular contains a photo and address of the card bearer, it does not contain a physical description, one of the key criteria for establishing satisfactory evidence of a signer's identity. While some local government agencies and private businesses, such as banks, may accept the matricula consular as identification, it is generally not reliable enough for Notaries. There is particular concern about the quality of the screening process in issuing the cards.
Only one state currently has laws explicitly recognizing the matricula consular as satisfactory identification: Nevada. States that don't have statutory criteria for acceptable identification documents technically allow the matricula consular for notarizations by default, though a Notary always has the option in those states of not accepting it. States that do have a list of acceptable identifying documents (e.g., California, Florida) do not specify it in statute as an allowed identifier. - National Notary Association
So what type of identity document is a Mexican National supposed to present as a reliable form of identification?
A Passport issued by their own country and perhaps even a Mexican drivers license. Of course, a Greencard, or border crossing card issued by the US would also be acceptable, as would a US drivers license, provided they can manage to get to Maryland to obtain one. (Reminder: Half of all Mexican Nations in the US are here legally.)
