Notarios, and how to protect your family

One word means two completely different things in Mexico and in the United States. That gap costs families their money and sometimes their case.

A couple at a dining table reading through paperwork together.

This is the article we most want people to read, because the harm it describes is common, expensive and almost entirely preventable.

The same word, two different jobs

In Mexico and much of Latin America, a notario público holds a demanding legal qualification. Years of formal study, a restricted appointment, and real legal authority. Trusting one with an important document is completely reasonable.

In the United States, a notary public is something else entirely. Here, a notary may witness a signature and confirm identity. That is essentially the whole job. There is no legal training requirement of the kind a Mexican notario has.

A notary in the United States cannot advise you on immigration law, cannot represent you, and cannot tell you what to file.

Why this particular gap causes so much damage

Someone arriving from a country where notario means something serious hears the word and reasonably assumes a similar level of authority. A person who wants to take advantage of that does not even have to lie outright. They only have to use the word and let the assumption do the work.

Families have paid thousands of dollars for forms that were filled in wrongly, filed in the wrong category, or never filed at all. Some have had applications damaged in ways an attorney then had to spend real effort undoing.

What to check before you pay anyone

  • Ask directly: are you an attorney licensed in Arizona? Ask for the bar number.
  • Check that bar number yourself in the State Bar of Arizona directory. It is free and public.
  • Be careful with anyone who says they are a consultant, an advisor, or an agency, without saying attorney.
  • Never sign anything in a language you do not read comfortably, and never sign a blank form.
  • Always keep a copy of everything you sign and every receipt.
  • Be wary of cash-only payment or of anyone unwilling to put the fee in writing.

If it has already happened to you

You are not the first, and it is not a failure of judgement on your part. The scheme is designed around a reasonable assumption.

The Arizona Attorney General's office takes consumer fraud complaints, including complaints about people practising law without authorisation. Reporting is worth doing even when the money is gone, because it can stop the next family losing theirs. An immigration attorney can also tell you whether anything filed in your name can be corrected.
