Legal framework of the authentication

Notary authentication is regulated in the Notary Code (Decree 314), particularly in Articles 54 through 59 and 78. It is an exclusive function of authorized notaries public (attorneys and notaries licensed in accordance with the law).

Types of authentication

1. Signature authentication (signature legalization)

The notary public attests that a person signed a document in their presence, or that the signature on a document is genuinely the signer's. It is the act in which the notary certifies:

  • The identity of the signer (through valid DPI national ID).
  • That the signature was placed voluntarily.
  • The date on which it was signed.

It is the most common type and the one requested by most institutions for private documents that will be formally filed.

2. Document authentication (certified copy / compulsa)

The notary public attests that a copy is a faithful reproduction of an original document physically presented. This is what is colloquially called a "legalized photocopy" or "certified copy." The notary:

  • Has the original in front of them.
  • Compares it against the copy.
  • Certifies that the copy is exact.

Useful when an authority requires a certified copy of a document you don't want to hand over in original form (national ID, university diploma, birth certificate, deed).

Difference between authentication and authenticity

Beware of the confusion: the notary authentication does not make the document "true" — it only certifies a concrete fact: that the signature was placed before the notary public or that the copy matches the original. The content of the document remains the responsibility of whoever issued it.

What is notary authentication used for?

The most common uses:

  • Administrative procedures: filings before SAT (tax), IGSS (social security), MINTRAB (labor), municipality, ministries.
  • Judicial proceedings: private documents filed as evidence.
  • Banking institutions: credit applications, opening of business accounts.
  • Immigration: signatures on invitation letters, travel authorizations for minors.
  • Educational procedures: filing of diplomas, academic certifications.
  • Registry filings: certain supporting documents.
  • Prior step to the apostille: for a Guatemalan private document to be apostillable, it must first go through notary authentication.

Step by step for a signature authentication

  1. You arrive with the document already drafted (either unsigned or already signed, as applicable).
  2. You present your valid DPI to the notary public.
  3. You sign before the notary (if the signature has not yet been placed), or you acknowledge the signature as your own (if it was already placed).
  4. The notary affixes their authentication certification at the foot of the document, with date, place, seal and their own signature.
  5. The notary records the act in their Authentications Book, a mandatorily registered book.

Step by step for a document authentication

  1. You present the original document you want to certify.
  2. You also bring the legible copy or photocopy you want to authenticate.
  3. The notary compares the original against the copy and verifies that they match.
  4. The notary affixes the notarial certification attesting to the fidelity of the copy.
  5. The notary records it in their Authentications Book.

Notary authentication + apostille: the mandatory path for international use

If a Guatemalan private document is going to be used abroad (power of attorney, sworn statement, private notarial act), the normal path is:

  1. Notary authentication of the signature or of the document.
  2. Authentication of the notary's signature at the Ministry of Foreign Affairs (MINEX) — this is the apostille.
  3. Sworn translation into the language of the destination country, if applicable.

Without the prior notary authentication, the apostille cannot proceed. That is why many international procedures get delayed for lack of this initial step.

Timing and cost

  • Timing: the authentication is done while you wait. It takes minutes at the notary's office.
  • Cost: very accessible (a few dozen quetzales) for simple procedures; it varies depending on complexity and urgency.
  • Validity: indefinite — the authentication does not expire. What can expire is the underlying document.

Common mistakes that invalidate an authentication

  • Expired or illegible DPI at signing — the notary cannot attest without valid identification.
  • Signature placed beforehand and without acknowledgment before the notary — only valid if the notary records that you recognize the prior signature as your own.
  • Incomplete document or with corrections made after the authentication.
  • Not authenticating every page in multi-page documents — some authorities require certification on each page.
  • Confusing authentication with a plain copy — a "legalized photocopy" without a notarial certification is not an authentication.

Frequently asked questions

Does the notary authentication expire?

No, the notary authentication has no expiration date. What can expire is the underlying document (a power of attorney with limited duration, a permit, etc.). The notarial certification remains valid indefinitely.

Can I authenticate a copy of a copy?

No. Authentication requires the notary public to have the original document in view. If only a plain copy is available, authenticity cannot be certified.

Is notary authentication equivalent to an apostille?

No. Notary authentication is a prior step. For international use, after the notary authentication you need the apostille seal at MINEX, which certifies the notary's signature.

Can any attorney perform authentications?

No. Only attorneys licensed as notaries public. Make sure your notary is registered and active — acts by unlicensed notaries are void.

Is the notary authentication valid for use in any country?

For countries party to the Hague Convention: notary authentication + apostille are sufficient. For non-party countries: notary authentication + legalization at MINEX + consular legalization by the destination country.

Can I authenticate someone else's signature if I bring their ID?

No. The signature is authenticated in the presence of the signer. Identity is verified by their DPI present. You cannot authenticate the signature of an absent third party.

Can the authentication be done electronically?

Yes, in Guatemala there is the figure of the electronic notary for certain acts. For sensitive documents or those going abroad, physical authentication remains the safer practice.
