The short answer: foreigners can buy land in the south of Chile, including Patagonia, on the same terms as Chileans. What makes the south different is not who may buy but what is being bought: rural land with rules on subdivision and building, coastline that belongs to the State, indigenous land that cannot be sold, water that is a separate right, and access that has to be on paper. Each of those is checked before you sign, not after.
This guide is also available in Hebrew (עברית) and German (Deutsch).
What you are actually buying in the south
"The south" covers the Araucanía, the Lake District around Puerto Varas and Puerto Montt, the island of Chiloé, and Patagonia proper — Aysén and Magallanes. Outside the towns almost everything for sale is rural land: a plot carved out of a farm, a share of a larger property, a lakeside or seaside lot, a farm itself. The legal questions follow from that, and they are not the ones a city purchase raises.
Rural plots: subdivision and what you may build
Rural land of agricultural, livestock or forestry use may be divided into lots of at least 0.5 hectares under Decree Law 3.516, with the subdivision certified by the Agriculture and Livestock Service (SAG). Those are the parcelas on most listings. The lot remains rural: the subdivision does not turn it into urban land, and outside urban limits the General Urban Planning and Construction Law restricts building to what the rural use needs — which broadly includes the owner's own home, but not an urban development.
Before you pay for a view: confirm that the lot exists as a separate, registered property with its own subdivision approval, and ask the municipal works department what you may build on it. A lot sold "on a plan" that was never approved, or a house that can never get a permit, are the two most expensive surprises in this market.
Buying a share of undivided land
Much of what is offered in the south is not a lot but a share — acciones y derechos — in a larger property held in common. Buying one makes you a co-owner of the whole, not the owner of the piece the seller pointed at on the ground. Turning that share into a defined, separate lot requires a partition among all co-owners. It can be a sound purchase, but only if you know that is what you are buying and what the path to a separate title looks like.
Indigenous land
This is the most important check in the Araucanía and much of the Lake District. Under article 13 of Law 19.253, indigenous lands cannot be sold, seized, mortgaged or acquired by prescription, except between indigenous communities or persons of the same ethnic group. Contracts made in breach of the rule are absolutely void — so a purchase price paid in good faith does not make the buyer the owner. The status of the land is checked before anything else, against the registry and the records of the National Indigenous Development Corporation (CONADI).
The coastal strip
State-owned beach land within a strip 80 metres wide from the high-water line cannot be sold under any title; it can only be the subject of administrative acts, such as concessions (Decree Law 1.939, article 6). A seaside listing that seems to include the shore may be selling land behind a strip that belongs to the State. Where the boundary actually runs is a question for the title and the plans, not the photographs.
Border zones and dual nationals
Foreigners in general may buy in Patagonia. The restriction in Decree Law 1.939 concerns land in border zones and nationals of the neighbouring country — Argentina, Bolivia or Peru. Because much of Patagonia lies in border zones, anyone who also holds one of those nationalities should raise it before negotiating anything. The question arises, for example, with Israeli buyers who also hold an Argentine passport.
Titles regularised by the State
In the south many titles began with a regularisation of small rural property under Decree Law 2.695, by which the State recognises a long-standing occupier as owner. Those titles are legitimate, but for a period after registration they remain exposed to claims from third parties, and the rules on those periods have been amended in recent years. A title search in the south therefore asks not only who owns the land, but how that ownership began and whether the window for challenges has closed.
Water rights
A stream across the land or a lake at its edge does not give you the right to use the water. In Chile water rights are separate rights, registered in the Water Property Registry of the Conservador de Bienes Raíces. Rights granted by concession now last thirty years and are extended automatically unless the water authority shows they were not used or that the source is at risk (Water Code, article 6, as amended in 2022). If the plan depends on water — for a house, a garden, animals or a business — the rights are checked and, where they exist, transferred with the land.
Access
A track that everyone has used for twenty years is not, by itself, a legal right of way. Plots carved out of larger properties depend on easements (servidumbres de tránsito) that should be constituted and registered. A lot with no registered access can leave you negotiating with a neighbour for the right to reach your own land.
Doing it from abroad
None of this requires you to be in Chile. The registries are local — Puerto Varas, Castro, Coyhaique, Punta Arenas — but certificates are obtained remotely, and the purchase itself runs on a power of attorney signed before a Chilean consulate or apostilled where you live. We handle the whole operation: see buying property in Chile remotely.
