Ley 26.209 — Ley Nacional de Catastro

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.

Ley 26.209 — catastro

Ley 26.209 sets the national framework for the provincial cadastral offices. Each province runs its own Dirección de Catastro, which determines the estado parcelario and the valuación fiscal of every parcel.

Why this is an auction page, not an administrative footnote

The valuación fiscal is the input to the auction base. Under CPCCN art. 566 the opening base for real property is two-thirds of the valuación fiscal, and provincial codes follow the same logic.

Argentine valuación fiscal has historically sat far below market value, and sustained inflation has widened the gap between revaluations. The consequence for anyone reading an auction listing:

• A base is not an appraisal and not a floor on value. It is a fraction of a cadastral number that may itself be years stale.
• A property whose base looks absurdly low is usually not mispriced by the court — the court is applying a statutory formula to a stale input. Real price discovery happens in the bidding.
• Conversely, a low base tells you nothing reassuring about encumbrances. Cheap and clean are unrelated questions.
