At the end of the world, estates are usually simpler: an apartment in Ushuaia, a house in Río Grande, sometimes an estancia in the north of the island. But Tierra del Fuego has a special tax regime and a young provincial justice system. Here is how inheritance works there.
Tierra del Fuego: geography and economy
Tierra del Fuego, Antártida e Islas del Atlántico Sur is Argentina’s southernmost province and its newest, created in 1990 from a former national territory. Its effective territory is the Argentine eastern part of Isla Grande de Tierra del Fuego, shared with Chile, plus Isla de los Estados and smaller islands. Argentina also includes within the province its claims to the Antarctic sector and the South Atlantic islands, including the Malvinas. The island borders Chile to the west, the Beagle Channel to the south and the Atlantic to the north and east. The capital, Ushuaia, on the Beagle Channel, is often called the southernmost city in the world. The 2022 census figure was about 186,000 inhabitants, mostly in Ushuaia, Río Grande and Tolhuin.
The north of the island is flat steppe, where sheep estancias founded in the late 19th and early 20th centuries surround Río Grande, a city famous for sea-trout fishing. The south is mountainous: the eastern end of the Andes bends here, and Ushuaia sits between snow-capped peaks and the channel, next to Tierra del Fuego National Park. In between lies Lago Fagnano (Khami), with Tolhuin on its shore, and forests of lenga and ñire beech. The climate is cold and windy, with mild summers and long winters.
Since 1972 the national Ley 19.640 has created a special customs and tax area in the island, with exemptions from several national taxes, to promote settlement and industry. This produced a large electronics and appliance assembly industry in Río Grande and Ushuaia. Oil and gas, sheep farming, fishing, forestry and tourism (Ushuaia is the main port for Antarctic cruises) complete the economy.
Ushuaia homes and Río Grande industry
Most estates involve apartments and houses in Ushuaia or Río Grande, vehicles, savings and work-related benefits from the manufacturing or public sector. Some include sheep estancias in the north, or lots and cabins around Tolhuin and Lago Fagnano. Some urban land originated in provincial or municipal land allotment programmes, whose conditions should be checked.
Ushuaia, Río Grande and the national law of inheritance
Many Fuegian estates belong to people who came south to work: an apartment in Ushuaia bought with years of factory or public-sector wages, a house in Río Grande, a plot in Tolhuin, savings, a vehicle bought under the special customs regime. Their heirs are often back in Buenos Aires, Córdoba or abroad, with relatives in Chile just across the island. Shares come from the Código Civil y Comercial de la Nación.
What the family is guaranteed
Article 2445 fixes the reserved portions. When a Fuegian worker dies leaving children, they are guaranteed two-thirds; with no children, parents are guaranteed half; and a husband or wife is guaranteed half. A will can distribute freely only what lies outside those portions. Protected heirs can have excessive legacies or gifts reduced.
Who inherits by law
Without a testament, descendants are first in line and share with the spouse. With no descendants, ascendants share with the spouse. Then the spouse inherits by himself or herself, and only after that siblings, nephews, nieces and other relatives to the fourth degree. The province takes nothing unless the estate is heirless.
The couple’s apartment
Consider an Ushuaia apartment bought by a married couple. Half belongs to the survivor from the outset. Any children receive the deceased’s half of that community; in assets that were the deceased’s alone (a house inherited back in Córdoba, for instance) the survivor takes a portion equal to each child’s. If no children but the deceased’s parents are alive, the survivor’s share is half. The Code also lets the survivor live on in the apartment for life, free of charge (article 2383), unless a third party co-owned it.
Chile and beyond
For relatives in Punta Arenas or Porvenir, jurisdiction depends on the last domicile (article 2643), but Fuegian courts always have it for land in the province, and Argentine law governs that land (article 2644).
Wills
A handwritten will has to be in the testator’s own writing from start to finish, dated and signed (article 2477). The notarial alternative is described in article 2479, where a public will requires a notary and two witnesses. If a will was also signed in Chile or elsewhere, check dates and wording carefully, since under article 2513 a later will revokes an earlier one unless it expressly keeps it. Coordinating two countries’ wills is covered on our wills page.
Courts and procedure on the island
The province’s Código Procesal Civil, Comercial, Laboral, Rural y Minero governs the case. Depending on where the deceased lived, the case is lodged in Ushuaia or Río Grande before the first-instance judge for civil and commercial matters. There are two districts: the Southern District, based in Ushuaia, and the Northern District, based in Río Grande, which also covers Tolhuin. The Superior Tribunal de Justicia sits in Ushuaia.
A Fuegian file opens with the civil records; the court then queries the wills registries and has the edict published a single time, after which claimants get thirty days (article 2340). Then the judge declares the heirs or approves the will, followed by the inventory and the partition, and finally the provincial property registry enters the heirs on each parcel using the cadastre’s plans. AREF, the provincial revenue agency, issues valuations and certificates. A family that would rather sell an Ushuaia flat than keep it can have a notary convey it straight from the estate. With cooperative heirs, the declaratoria usually takes four to eight months.
Ley 19.640 and taxes
Tierra del Fuego has no inheritance tax in 2026. Ley 19.640 grants exemptions from certain national taxes for activities and assets in the special customs area. Whether those benefits apply to a particular heir’s situation (for example, to the federal wealth tax on assets located on the island) is a technical question for an accountant. The ordinary expenses remain: a judicial fee proportional to the estate, lawyers’ fees, stamp tax on certain private documents, and any property or municipal tax still owed. Vehicles bought under the special regime may face conditions if moved to the mainland.
Rural land and the Chilean border
On October 9, 2026 the Supreme Court halted the decree repealing Ley 26.737, so its caps on foreign rural ownership reach Tierra del Fuego too. The island shares a land border with Chile, so border security zones cover significant areas, and Lago Fagnano and the coastal fringe may raise the water-body question for foreign heirs. A foreign son or daughter protected by forced heirship keeps the land regardless, while its area is added to the national records.
Heirs in Chile or further away
A Chilean power of attorney is apostilled like any other, and Chilean civil records need an apostille but no translation. Heirs in the U.S. or Europe add a sworn translation in Argentina. Every heir without a DNI should get a CDI from ARCA. Because flights to Ushuaia are long and expensive, remote management through a lawyer with a power of attorney is usually the practical choice.
A Río Grande example
A factory worker from Río Grande dies leaving a house bought during his marriage, a car and savings. His widow and two adult children, one in Córdoba and one in Spain, are the heirs. The widow keeps half of the house and car as her community share; the children inherit the other half. The Spanish heir signs a power with an apostille. The family decides that the widow will keep the house, using article 2383’s right of habitation in the meantime, and the children agree to transfer their shares to her in exchange for the savings.
Common Fuegian issues
- Homes from provincial or union housing programmes with conditions on sale.
- Vehicles and goods bought under the special customs area, which may face conditions if taken to the mainland.
- Heirs who returned north long ago and have lost touch with the property.
- Lots in Tolhuin or the outskirts of Ushuaia whose subdivision was never completed.
Tierra del Fuego FAQ
Does the Ley 19.640 regime mean heirs pay no taxes?
No. It exempts certain national taxes for activities and assets in the special area, but it is not an inheritance exemption; there is no inheritance tax anyway. Court and professional fees and provincial and municipal charges still apply.
Which court handles a succession in Tolhuin?
The Northern Judicial District, based in Río Grande.
My father’s apartment came from a provincial housing plan. Can we inherit it?
Yes, but check whether the plan’s conditions were met and a final deed issued. Some housing programmes restrict sale or require the instalments to be paid off first.
Can we sell the Ushuaia apartment without travelling?
Yes. Once the heirs are declared, the person holding their power of attorney can sign the deed in Ushuaia while they stay at home.
