Ley 17.801 — Registro de la Propiedad Inmueble

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 17.801 — the registry framework

Argentina has no national land registry. It has 24 provincial registries operating inside one national statute, Ley 17.801. Registration is generally declarative — it makes a right effective against third parties (oponible a terceros) — rather than constitutive of the right between the parties.

The two products, and why the difference matters

	informe de dominio	certificado de dominio
Purpose	Information	Requested by an escribano for a specific act
Who may request	Generally anyone with a legitimate interest	The acting escribano (or, for a judicial act, the court)
Priority effect	None	Triggers the bloqueo registral

The bloqueo registral — also called reserva de prioridad — is the mechanism that makes Argentine conveyancing safe without a title-assurance market. When the certificado issues, the registry reserves priority for the intended act for a short statutory window, so that a competing embargo, hipoteca or sale registered during the window cannot defeat it. The escribano closes inside that window.

Do not treat an informe as diligence for a closing.

An informe de dominio is a snapshot with no reservation attached. Anything can be registered the next morning. See bloqueo-registral.

Anotaciones personales

Separately from the parcel index, the registry keeps a personal index: inhibición general de bienes recorded against a named person, which blocks that person from disposing of property. A search of the parcel alone will miss it. See inhibicion-general-de-bienes.

In a subasta

The court’s oficio judicial is what gets the transfer registered — there is no escritura from a seller to present. The buyer’s diligence before bidding is nonetheless registry diligence: informe de dominio on the parcel, plus anotaciones personales on the ejecutado, to see the full picture of hipotecas, embargos and inhibiciones that will have to be dealt with in the distribution.
