Argentine Inheritance Law: A Guide for Foreign Heirs 

You don’t need to travel to Argentina if you inherit property. The entire process can be handled remotely.

If you have inherited assets in Argentina, you will most likely need to go through a local probate proceeding—regardless of where you live or where the deceased was domiciled. This is one of the most common and often unexpected issues faced by foreign heirs and international attorneys dealing with cross-border estates involving Argentine assets.

This guide provides an overview of the key principles of Argentine inheritance law, including the rules governing forced heirship, the distinction between testate and intestate succession, and the practical steps involved in opening and completing a probate proceeding in Argentina.

The Legal Framework

Under Argentine law, jurisdiction over succession matters is primarily determined by the last domicile of the deceased. .

If the deceased was domiciled in Argentina at the time of death, Argentine law will govern all aspects of the succession, including the determination of heirs, the validity of any will, and the distribution of assets — wherever those assets may be located.

If the deceased was domiciled abroad at the time of death, foreign law may govern certain aspects of the succession — such as the determination of heirs and the validity of a will. However, there is an important exception: Argentine law always applies to real estate located in Argentina, regardless of the domicile of the deceased. 

For estates that include both real estate and other assets — such as bank accounts or financial investments — located in Argentina, it is important to assess early on which law governs each category of assets and how the Argentine proceeding should be coordinated with any foreign probate or succession process.

Forced Heirship: The Legítima

Argentine succession law includes mandatory heirship rules (“legítima“) that may differ significantly from those in common law jurisdictions. These rules limit the extent to which a person can freely dispose of their estate and may override certain provisions of a will executed abroad.

Certain heirs — known as “herederos forzosos” or forced heirs — are entitled to a protected portion of the estate that cannot be taken away by will or by lifetime gifts. These forced heirs are:

• Descendants (children, grandchildren): entitled to two-thirds of the estate
• Ascendants (parents, grandparents): entitled to one-half of the estate
• Surviving spouse: entitled to one-half of the estate

If the deceased had children, they are legally entitled to at least two-thirds of the estate, and any testamentary disposition or lifetime transfer that reduces their share below that threshold can be challenged in court.

For foreign heirs and international attorneys, this is a critical point: even if a will executed abroad purports to leave the entire estate to one person, Argentine courts may apply the forced heirship rules to any assets located in Argentina.

For example, if the deceased left an estate valued at USD 300,000 and was survived by three children and no spouse, the children would be entitled to at least USD 200,000 to be divided equally among them — USD 66,667 each — leaving only USD 100,000 available for testamentary disposition to others.

Testate vs. Intestate Succession

Argentine law distinguishes between two types of succession:

Testate succession occurs when the deceased left a valid will (“testament”). Argentine law recognizes two forms of will: entirely handwritten and signed by the testator and executed before a notary public. Foreign wills may also be recognized in Argentina, subject to compliance with applicable requirements and, where necessary, apostille certification.

Intestate succession occurs when the deceased left no valid will, or when the will does not cover all of the assets. In this case, Argentine law establishes a fixed order of priority among heirs: descendants come first, followed by ascendants, and the surviving spouse. Collateral relatives such as siblings may inherit only in the absence of descendants, ascendants, and a surviving spouse.

Opening the Probate Proceeding

Regardless of whether the deceased left a will, an Argentine probate proceeding must be opened before an Argentine court with jurisdiction over the matter. Jurisdiction is typically determined by the last domicile of the deceased in Argentina, or — if the deceased was not domiciled in Argentina — by the location of the assets.

The proceeding is initiated by filing a petition with the competent court. The court will then issue a declaration of heirs (“declaratoria de herederos”), which formally recognizes who the legal heirs are. This declaration is a prerequisite for transferring or selling any assets — including real estate — that formed part of the estate.

In straightforward cases where all heirs are cooperative and the assets are clearly identified, the process can be completed in a matter of months. When disputes arise among heirs, or when the estate includes complex assets or international elements, proceedings can take considerably longer.

Cross-Border Succession: Key Considerations

When an estate involves assets or heirs in multiple countries, the complexity increases significantly. Some of the most common cross-border issues include:

• Recognition of foreign heirs: Foreign heirs must be formally recognized by the Argentine court. This typically requires the apostille certification of foreign documents such as birth certificates, marriage certificates, or death certificates.
• Coordination between jurisdictions: When probate proceedings are open in more than one country, it is important to coordinate the proceedings to ensure consistency and avoid conflicting outcomes.
• Real estate transfers: Transferring or selling inherited real estate in Argentina requires the completion of the Argentine probate proceeding and the registration of the transfer with the Argentine land registry (Registro de la Propiedad Inmueble).
• Powers of attorney: Heirs who are unable to appear in Argentina in person will typically need to grant a power of attorney to a local attorney to act on their behalf in the proceedings. This means we can handle the entire probate process remotely; you do not need to travel to Argentina at any stage

A Note for International Attorneys

For attorneys based outside Argentina who are handling an estate with Argentine assets, engaging local Argentine counsel early in the process is strongly recommended. Argentine probate proceedings are conducted entirely in Spanish, before Argentine courts, and in accordance with Argentine procedural rules. Local counsel can assist with filing the probate petition, coordinating the preparation and apostille certification of foreign documents, representing heirs before Argentine courts, and managing the transfer or liquidation of Argentine assets.
