Nulidad de Subasta — Attacking a Completed Sale

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.

Nulidad de subasta

Once the property has sold, the route back is not repurchase — there is none — but annulment, and annulment requires a defect.

Typical grounds

• Defective `edictos` — publication omitted, short, in the wrong outlet, or materially misdescribing the property.
• Notice failure to the ejecutado or to a party entitled to be heard.
• Procedural irregularity in the auction act itself.
• Material misdescription — the wrong parcel, wrong surface, wrong improvements, or a substantial discrepancy between what was advertised and what exists.
• Price so low as to shock, generally only in combination with another defect rather than standing alone.

Timing

Narrow, and it tightens sharply around the auto de aprobación del remate. The practical rule of thumb is that objections must be raised promptly and within the executing file — a party who watches the process and complains afterwards is unlikely to succeed. Exact periods are provincial and needs_verification.

What it means for the buyer

This is the principal legal risk in Argentine auction buying, and it is a procedural risk rather than a title-chain risk. The buyer’s protection comes from the regularity of the process, so the buyer’s exposure is to the process being irregular — something the buyer did not cause and often cannot detect.

Practical mitigation:

• Read the edictos against the informe de dominio and the cadastral data. A discrepancy visible to you is a discrepancy a court can later act on.
• Confirm the ejecutado was properly served, as far as the file shows.
• Treat the period before the auto de aprobación as the risk window, and be cautious about irreversible spending on the property until it has passed.

What the buyer recovers on annulment — price, costs, improvements — is needs_verification and turns on good faith and on the ground of annulment.

Distinguish

Annulment is not `purga`. Paying money after the sale does not annul it. There must be a defect.
