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.

Zona de seguridad de fronteras

A real and enforceable restriction on foreign acquisition, and one that catches buyers looking at exactly the kind of scenic land they are most likely to want.

ElementPosition
Land border zoneWithin 50 km of a terrestrial border
Maritime border zoneWithin 100 km of the maritime border
RequirementPrior authorisation from the Comisión Nacional de Zonas de Seguridad
Effect of proceeding without itThe transaction is null and invalid
Borders affectedChile, Bolivia, Paraguay, Brazil, Uruguay

Practical reach

The affected band is wide and includes substantial parts of Patagonia, the Andean provinces, Misiones, Formosa, Chaco, Corrientes, Entre Ríos and the Atlantic coastal strip. Much of the land a foreign buyer finds attractive — lakes, mountains, coast — sits inside it.

At a subasta

The restriction is on acquisition, and a judicial sale is an acquisition. A foreign bidder who wins a subasta on a parcel inside the zone, without authorisation, has a serious problem: the constitutional and administrative validity of the acquisition, not merely a delay in registration.

Check the parcel’s position against the zone before bidding, not after.

Constitutional debate

The restriction’s compatibility with the equal-treatment guarantees of the Constitución Nacional — which extend rights to todos los habitantes — has been questioned in the Argentine literature. That debate has not changed the operative requirement. Treat the authorisation as mandatory.

Interaction with rural land

A parcel can be caught by both this regime and Ley 26.737. They are separate requirements with separate authorities; satisfying one does not satisfy the other.
