Argentina power of attorney (poder notarial) at a US consulate

A power of attorney (poder notarial) is a legal document that authorizes another person — your apoderado — to act on your behalf in Argentina. You sign the document in front of the Argentina consul in the US, and the consul’s signature and seal makes it valid for use in Argentina without further notarization there.

This procedure is one of the most common reasons Argentina citizens in the US visit their consulate. Selling family property, representing a sick relative, registering a deceased parent’s estate, managing a Argentina bank account from abroad — all require a poder notarial.

Types of power of attorney (poder)

Each country has slightly different categories, but generally:

  • General power (poder general) — broad authority covering most matters except specific listed acts (often used for relatives managing your affairs while you live abroad)
  • Special power (poder especial) — limited to specific transactions (e.g., “to sell the property at [address]”)
  • Power for litigation (poder para pleitos) — authorizes a Argentina lawyer to represent you in court
  • Power for inheritance (poder para sucesión) — authorizes an apoderado to handle your share of an estate

The narrower the better legally — only grant the powers the apoderado actually needs.

Required documents

To obtain a Argentina poder notarial at a US consulate, you typically need:

  • Valid Argentina passport (or in some cases other Argentina government ID)
  • Identity of the apoderado — full legal name and Argentina ID number (DNI, cédula, CURP, etc.)
  • Description of powers to be granted — what specifically the apoderado may do
  • US proof of address (utility bill or lease less than 3 months old)
  • Photo ID with current photo
  • Draft text of the poder if you have a Argentina lawyer who prepared it; otherwise the consulate has standard forms for common purposes
  • Fee — about US$40 per 25 lines (renglones) for the escritura plus US$40 per 25 lines for the required testimonio (certified copy) — so a typical short poder runs about US$80 total; longer documents cost more (Argentine consular notarial fees are priced by document length, not a flat fee); money order or cash (confirm the current amount)

Step-by-step process

  1. Decide what powers you need to grant. If complex (litigation, inheritance, property), consult a Argentina lawyer who can prepare a draft.
  2. Schedule appointment at your local Argentina consulate
  3. Gather documents per checklist above
  4. Attend appointment in person — you sign in front of the consul
  5. Pay fee — about US$40 per 25 lines (renglones) for the escritura plus US$40 per 25 lines for the required testimonio (certified copy), so a typical short poder runs about US$80 total; longer documents cost more (confirm the current amount)
  6. Receive notarized document — same-day in most cases
  7. Send the original to Argentina via courier or hand-carry on your next trip

Revoking a poder

You can revoke a poder at any time by signing a revocación (revocation) at the same consulate. The revocation is sent to Argentina so the apoderado can no longer use the original poder. Notify the apoderado directly so they know you’ve revoked their authority.

For matters involving real estate or registries, the revocation often must be filed with the relevant Argentina registry to be effective against third parties.

Witnesses and additional requirements

Some Argentina povers require witnesses (testigos) — friends or family who are not the apoderado, willing to sign at the consulate. Verify whether your specific power requires witnesses before the appointment.

For matters that will be recorded in a Argentina registry (real estate, marriage, business), the consul may need to add specific stamps or certifications. Tell the consul at the appointment exactly what the document will be used for so they can format it correctly.

Apostille — usually not needed

Documents notarized at a Argentina consulate in the US are valid in Argentina without further apostille — the consul’s signature and seal is itself official recognition. Apostille is needed when transferring documents between countries that are both parties to the Hague Apostille Convention, not for documents already authenticated by a Argentina consul.

The apostille process applies when you need to send a US-issued document (US birth certificate, US marriage certificate, US court document) to Argentina.
