Is a Foreign Will Valid in Argentina? UK Wills and Argentine Assets

An English will can tell your family who should receive your Argentine flat, but it cannot transfer the title on its own. Argentina can recognise a will made in England and Wales in the required English form. The heirs must then go through Argentine succession proceedings, where protected family members may claim compulsory shares in the property.

The distinction matters most if the will leaves everything to a partner or friend. Where children survive, two-thirds of the estate governed by Argentine succession law is reserved for them. Scottish and Northern Irish wills follow different rules from those covered here, and the deceased's domicile at death affects which law governs movable assets.

A valid will and the law that distributes the assets

Article 2645 of Argentina's Civil and Commercial Code recognises the form of a foreign will if it complies with the law of the place where it was made, or the relevant law of domicile, habitual residence or nationality. Form concerns how the document was executed. Under article 2644, succession generally follows the law of the deceased's domicile at death, while Argentine immovable property follows Argentine law. British nationality and UK tax residence do not, by themselves, establish a person's Argentine domicile.

An English probate grant is evidence of the English process, rather than a deed transferring an Argentine home. Before buying, the proposed title and ownership arrangements deserve attention alongside the will; the buying property in Argentina guide and Argentine homes for sale provide the purchase context.

What a protected heir can claim

Argentina's legitimarios are descendants, ascendants and a surviving spouse. Under articles 2444–2445, descendants together are entitled to a reserved two-thirds. Without descendants, ascendants have a reserved one-half, as does a surviving spouse. With no protected heirs, the estate is generally freely disposable. The fractions concern the estate distributed under Argentine law, rather than the combined value of everything both spouses own; debts, marital-property status and earlier gifts affect the calculation.

Suppose, hypothetically, a widowed owner domiciled in London leaves an Argentine flat worth US$150,000. There is no mortgage or other relevant asset, and the owner has two children but leaves the flat to a friend. On those simplified facts the children's compulsory portion is US$100,000, or US$50,000 of value each; at most US$50,000 remains for the friend. An indivisible flat may need a sale or buyout, and a child can seek reduction of the excessive gift. A spouse, debts or marital property would change that arithmetic.

An unmarried partner does not gain forced-heir status simply by living with the owner. A partner named in the will can inherit within the freely disposable portion; the way any jointly owned property was acquired also matters.

Choosing between one will and two

One properly executed English will can cover the assets, provided the heirs present the authenticated document and Spanish translations in Argentina. A second will confined to Argentine assets may spare some translation and proof-of-form work. An Argentine testamento por acto público is executed before a notary and witnesses in a locally familiar form; a wholly handwritten, dated and signed testamento ológrafo is also possible, though it may need extra verification after death. Both remain subject to compulsory shares and the court process.

Two wills require precise asset boundaries. A later blanket clause revoking all earlier wills might cancel the English one. GOV.UK warns that marriage cancels an earlier will, so ask your English solicitor about exceptions and the separate effects of divorce. Marriage, divorce, a child's birth, a change of domicile or a purchase can change the plan. Tax is a separate calculation, covered in the UK Inheritance Tax guide.

From UK records to an Argentine title

After a death, the Argentine lawyer needs to establish both the heirs and the assets: the executed will or official copy, death certificate, evidence of family relationships, title deed, bank details and liabilities, alongside information on domicile and any English probate application. A sale timetable depends on the heirs and title being established first.

UK records requested by the court may need certification, an FCDO apostille and Spanish translation by a traductor público (sworn translator). The published standard paper apostille fee is £45 per document, plus courier or postage costs; the document submitted determines whether a will or probate copy first needs certification. Physical papers also take time to handle and ship. For a Buenos Aires City filing, ask the court and translator which Colegio de Traductores Públicos certification is required. The apostille authenticates the document's signature, while the translation makes its contents usable in court. The UK apostille steps explain the UK side.

The lawyer opens a sucesión, a judicial inheritance case. Article 2643 provides for jurisdiction at the last domicile and, for Argentine land, where the land is located. The court receives the will, death record, kinship evidence and property details; potential heirs and creditors may need notice. The judge examines the will or, without one, issues a declaratoria de herederos (declaration of heirs). Ask the lawyer for a case-specific timetable, allowing for disputed claims and document work. Lawyer, translator, registry and court costs vary by province, estate and work required, so an itemised quote is more useful than a single headline fee.

The court's directions allow inheritance or an authorised sale to be registered with the relevant Registro de la Propiedad Inmueble (land registry); banks receive the orders they require. An escribano (civil-law notary) handles a later deed if needed. Heirs staying in Britain can ask the lawyer to arrange a poder (power of attorney) for the required inheritance and property acts. Before execution, confirm the available consular or UK notarial route, document authentication and sworn translation requirements with the lawyer and receiving authority. The power of attorney guide explains the choices.

The tax and ownership questions beside the will

Ask the estate's Argentine accountant to check inheritance and gratuitous-transfer taxes in the relevant province. Do not assume Buenos Aires Province and Buenos Aires City have the same tax treatment. From 6 April 2025, UK Inheritance Tax worldwide-property exposure is based on long-term UK residence, generally 10 of the previous 20 UK tax years, with a 3–10-year tail after departure depending on residence history. UK-situated assets may remain taxable after worldwide exposure ends. A single UK and Argentine asset schedule helps the estate account for the flat once and apply each country's rules to it.

Giving property away during life or buying through a partner can still leave questions about gifts and marital-property accounting in the succession case. Someone who owns no Argentine assets can stay with UK will and probate guidance. For a purchase still under consideration, the property due-diligence checklist belongs before the decision about title.
