I bought land in the north and it was indigenous land: why the contract is void

Quick answer: indigenous lands cannot be transferred, seized, encumbered or acquired by prescription, except between indigenous communities or individuals of the same ethnic group. That is what article 13 of Law 19,253 says, and it adds something almost nobody anticipates: acts that breach that prohibition are void and without any effect. This is not a contract that can be cured afterwards, nor a defect that time corrects. In the north this reaches the lands of Aymara, Atacameño, Quechua and Colla communities and individuals, and it is detected before paying by checking the Register of Indigenous Lands, which is a register separate from the Real Estate Registrar (Conservador de Bienes Raíces).

It is one of the harshest situations a buyer can face. They paid, they signed before a notary, they may even have been occupying the land for years, and then they discover that the whole transaction has no validity from the outset. Not necessarily because anyone deceived them: very often not even the seller knew that their land was recorded in that register.

The north accounts for a good share of these cases, and not by chance. The native peoples of the far north and the altiplano have recognised ancestral occupation over extensive areas, and growing demand for land in Arica, Tarapacá and Antofagasta pushed through deals that should never have closed.

This risk does not appear on its own. It is one of the legal structures that set buying land in the north apart from the rest of the country, alongside the agricultural communities of the Norte Chico and the mining concessions that cover a good part of the territory. We go through all of them in the guide on buying land in northern Chile.

What land is indigenous according to the law

Article 12 of Law 19,253 defines indigenous lands and expressly names the peoples of the north alongside the other recognised ethnic groups. In general terms, these are the lands that indigenous individuals or communities occupy in ownership or possession deriving from titles recognised by the State, those deriving from títulos de merced (grant titles), those resulting from the division of reserves or the liquidation of communities, and those they have historically occupied and possess, provided their rights are recorded in the Register of Indigenous Lands.

That register is the piece of information that changes everything, and it is also the one almost nobody checks. A property can have its title registration perfectly in order at the Real Estate Registrar and also be recorded as indigenous land. The two coexist, and the second imposes a legal status the buyer knows nothing about until it is already too late.

What article 13 prohibits exactly

The legal protection operates on four fronts at once.

That last prohibition is the one that leaves many buyers with no way out. The strategy that works with ordinary land, waiting out the period and regularising through possession with title regularisation, is of no use: acquisitive prescription does not run against indigenous land.

Communities and individuals: two different regimes

The law treats the land of an indigenous community differently from the land of an individual indigenous person, and the distinction matters because it changes what can be agreed.

The distinction matters in practice because it changes the first thing that has to be verified. If the land belongs to a community, no lease, loan for use or assignment arrangement survives a later review, no matter how well the contract is drafted. If it belongs to an individual indigenous person, on the other hand, there is a narrow path, but it always runs through authorisation from CONADI: without it, the lease or the exchange meets the same fate as a direct sale, that is, nullity.

The exchange is the route the law designed to allow mobility without taking the land out of its protective status: indigenous land is swapped for land that is not indigenous, and the land that enters the indigenous estate acquires that status. It is not a mechanism for releasing land, it is a mechanism for moving it.

What it means for the act to be void

It is worth understanding the weight of this expression, because it is not the same as a voidable contract or one the parties can undo by agreement.

Absolute nullity means that the act produces no effects from the outset, that it is not cured by the passage of time in the way other defects are cured, and that it can be declared even if the parties agreed to keep the deal in place. The buyer never acquired ownership at any moment, and the Registrar should never have entered the registration.

What is left, then, is a different discussion from the one the buyer had imagined. It is no longer about defending a property, but about recovering what was paid and, depending on the circumstances, pursuing the liability of whoever sold knowing what they were selling. That claim runs against the seller, and its outcome depends entirely on whether that person has anything to answer with.

How it is detected before signing

The good news is that this is one of the few risks that can be ruled out completely before paying, as long as the check is done in the right place.

• Check the Register of Indigenous Lands. It is the step that settles the matter and it is independent of the check at the Registrar. An impeccable title registration says nothing about this.
• Review the origin of the title. Titles deriving from the settlement laws and from the State's later recognitions usually leave a trace in the chain of title, and that trace can be read in the title study when it is done in full and not only for the last few years.
• Consult CONADI. When there is doubt about the status of the land or of the people involved, asking the agency is cheaper than the lawsuit that follows.
• Be wary of the price. Land notably below market value in an area with a community presence usually has an explanation, and this is one of the most frequent ones. It is not the only one: titles with poorly defined shares and rights also explain low prices, even though the legal mechanism behind them is different.
• Do not rely on the seller's good faith as a guarantee. Good faith does not save the contract here. Nullity operates because of the nature of the land, not because of the intention of the person selling.

Frequently asked questions

Can I buy indigenous land if the seller agrees?

No, not if you are not an indigenous person of the same ethnic group. Agreement between the parties does not enable the transaction, because the prohibition in article 13 is not established in the seller's interest but as a rule of protection, and that is why breaching it produces nullity and not a defect the parties can waive.

I have been occupying the land for ten years. Can I regularise it through prescription?

No. Article 13 expressly excludes indigenous lands from being acquired by prescription. That is precisely the difference from ordinary land, where prolonged material possession opens the door to regularisation. Here time consolidates nothing, however many years have been spent fencing and working the land.

Can I lease indigenous land to set up a project?

It depends on whether it is community land or the land of an individual indigenous person. Community land cannot be leased, given in loan for use or assigned to third parties. The land of an individual indigenous person allows a lease for a maximum of five years and with authorisation from CONADI. Any contractual structure that tries to stretch those limits is exposed to the same nullity.

I already bought and I have been told it is indigenous land. What do I do?

The first thing is to verify the registration in the Register of Indigenous Lands, because not all land in an area with communities has that status. If it is confirmed, the route is not to try to consolidate ownership but to direct the claim against the seller to recover what was paid and the damages. Time works against you, so it is best to act as soon as it is detected.

Can CONADI authorise a sale to a non indigenous person?

CONADI authorisation is provided for specific situations, such as encumbering the land or exchanging it for non indigenous land of similar commercial value, not as a general route to lift the prohibition on transfer. Filing an application in the hope that it will enable an ordinary sale to a non indigenous third party starts from a mistaken premise.

Does this only apply to Mapuche communities in the south?

No. Article 12 expressly names the Aymara, Atacameño, Quechua and Colla peoples, among others, so the statute applies fully in Arica y Parinacota, Tarapacá, Antofagasta and Atacama. The mental association between indigenous land and the southern macrozone is exactly what causes the check to be skipped in the north.

The Registrar registered my purchase. Does that not validate the transaction?

No. Registration does not cure a void act. The Registrar enters registrations on the basis of the titles presented to it, and indigenous land status is recorded in a different register. The fact that the registration exists means there is an appearance of ownership, not that ownership was acquired.

Can indigenous land be inherited?

Succession on death is governed by its own rules and the law provides for transmission within the protective status, so the land does not lose that status when it passes to the heirs. It is a very different situation from a sale to a third party, and it is best processed as it should be, through the posesión efectiva (the estate probate filing).

I bought part of the property as shares and rights. Does that change anything?

It does not improve the situation. If the land is indigenous, the undivided share in it carries the same prohibition, and to that are added all the problems of buying a share instead of a lot with defined boundaries, which we explain in the guide on shares and rights.

How we handle it

We review the full chain of title and the property's situation in the Register of Indigenous Lands before you transfer a single peso. It is a short review and it is the only one that really rules out this risk, because the Registrar does not show it.

When the purchase has already been made, we assess the claim that lies against the seller and, before recommending a lawsuit, we check whether that person has anything to answer with. We prefer to say so at the start and not after two years of proceedings.

We have our own team of lawyers, surveyors and architects, which makes it possible to review in a single process both the chain of title and the physical situation of the property, without depending on outside providers for each report. The whole matter can be handled by power of attorney, without you having to travel at each stage.

Send us the property tax roll number or the deed you have in front of you, and we will tell you whether it appears recorded in the Register of Indigenous Lands and what steps follow from what we find.
