Argentina (AR) — civil law.

Nothing on this page describes United States practice. There is no certificate sold to an investor, no administrative sale, and no post-sale redemption window in Argentina. If you arrived carrying US assumptions, read falsos-amigos first.

CDI / CUIT — registering a non-resident

You cannot complete or register an Argentine property acquisition without a tax identification. Getting one is the first step, not a formality at the end.

The documentary set

ItemNotes
Passport or foreign identity documentValid
CDIClave de IdentificaciónThe identifier for a foreigner without residence; the analogue of CUIT/CUIL. Obtained from ARCA (the agency formerly called AFIP), by appointment, presenting the passport
Poder especialA special power of attorney, if you will not sign in person. Executed abroad, then legalised/apostilled and translated
Certificado de origen de fondosEvidence of the origin of the funds

Sources will say "AFIP".

AFIP was dissolved and replaced by ARCA under Decreto 953/2024. Guidance written before late 2024 refers to AFIP for the CDI appointment; it is the same institutional line. See arca.

Timing

This is the step that most often breaks a foreign auction purchase. Between winning a subasta and the deadline for the saldo there is not time to obtain a CDI from scratch, arrange an apostilled power of attorney, and move funds. Do it before you bid.

Residency is not required

Ownership does not require residency, a local company, or a local partner. What it requires is identification, funds you can evidence, and — for border-zone or rural land — a separate authorisation.

For a judicial auction specifically

Whether the portals admit a non-resident postor, and on what identification and guarantee terms, is needs_verification per platform. Take it from the platform’s own reglamento. See participar-en-la-subasta.
