Shares and rights in Chile: risks, irregular subdivisions and regularisation

Short answer: buying "acciones y derechos" (shares and rights) over a plot of land is not buying the plot you were shown. What gets recorded at the Real Estate Registry is an undivided share in the whole property, with no boundaries of its own and no individual tax roll. The plan with the numbered lots is never registered and binds nobody. When that operation is repeated twenty or thirty times over a single 5,000 square metre property, an irregular settlement is born: houses built, roads opened, and not one individual title. Article 138 of the General Urban Planning and Construction Act punishes the person who sets up that business with imprisonment, and Law 20,234 is today the only simplified route to regularise what has already been built.

This article deals with one specific and very Chilean situation: the rural property of half a hectare that is sold off in pieces through shares and rights. It is not an inheritance dispute between siblings. It is a business model, it repeats itself in the same format in every region, and it always ends in the same place, with families who have spent years living on land that legally is not theirs.

How the 5,000 square metre business is put together

The starting point is a rule about surface area. Decree Law 3,516 provides that rural properties located outside the urban boundary cannot be divided into lots smaller than 0.5 hectares, that is 5,000 square metres. That is why country plots are sold at exactly that size: it is the smallest unit the general rule allows anyone to create. The exceptions exist and are closed ended, but there are few of them and every one requires prior authorisation.

A seller who wants to place twenty 250 square metre sites on that same property runs into that wall. He cannot subdivide, because no public office will approve a plan showing lots below the minimum area. So he changes the instrument: instead of selling lots, he sells shares. To each buyer he transfers rights equivalent to one twentieth of the property, and separately hands over a plan drawn up privately with the sites numbered, sometimes an allocation of use agreement, sometimes an internal set of rules signed before a notary.

From the outside everything looks formal. There is a public deed, there is a notary, there is registration at the Conservador de Bienes Raíces, there is a sign with the lot number and very often a road opened with machinery. The buyer walks onto a site marked out with stakes, pays and receives stamped paperwork. What nobody explains is that the deed and the plan describe two different things, and that only one of them was registered.

What your deed says and what it does not say

Open your deed and look for the clause describing the thing sold. It will read something like this: the rights equivalent to five per cent of the property registered at page such and such, number such and such. It may be expressed as a percentage, as a fraction or as an equivalent surface in square metres. None of those three forms gives you a lot. All three give you the same thing: an ideal part of the entire property, spread evenly across every square metre and concentrated in none.

The plan, by contrast, is not registered. A plan only produces effects once the competent authority approves it, the Municipal Works Department inside the urban boundary or the Regional Ministerial Secretariat of Housing and Urban Development together with the Agriculture and Livestock Service outside it. The plan your seller handed you went through neither. It works as an agreement between those who signed it, and nothing more: it does not bind the co owner who buys later, it does not bind a creditor who attaches a share, and it does not bind a court that has to divide the community.

The sale itself is valid, which is why nobody stops it at the notary. Article 1812 of the Civil Code provides that where a thing is held in common by two or more persons undivided, each of them may sell their share even without the consent of the others. That rule exists so a co owner can dispose of what is his, not to manufacture subdivisions. But it works all the same, and that is the gap the whole business runs through.

If the deed also describes boundaries of its own, as though you were the exclusive owner of that piece, the problem gets worse rather than better: the seller is not registered as owner of a piece but of a share in the whole, and the Registrar rejects the registration over that contradiction.

The four rules the seller will not mention

The operation holds together because the buyer knows only one rule, article 1812, and that is precisely the one that works in the seller’s favour. These are the other four.

Article 138 names the community, and that changes everything

It is worth pausing on that last point, because it changes the whole conversation. The seller’s usual defence is that the law does not prohibit selling shares and rights, and that is true: article 1812 allows it. What the law does describe, in those words, is the constitution of communities aimed at forming new settlements, and it punishes that with a custodial sentence.

In other words, the shares and rights structure applied to a subdivision is not a legal vacuum or a grey area somebody discovered. It is precisely the conduct the legislator defined, using the very name it goes by. Someone who sells shares in a property so that twenty families can carve out sites is not exploiting a silence in the law: he is doing what an article of the planning code describes one act at a time.

This matters for two practical reasons. The first is that the buyer does not commit the offence, he suffers it: the rule targets the owner, subdivider or developer. The second is that his title is born of that operation, and that is why, when he reaches the Works Department or the water utility, doors close without anyone explaining properly why.

The wall that appears after signing

The problems do not arrive on the day of purchase. They arrive a year or two later, when the buyer wants to do something with his site. This is the sequence we see repeat itself.

• There is no separate tax roll. The Internal Revenue Service assesses the whole property under a single roll. Property tax bills arrive in the name of the original owner or of the community, and how the co owners split it is a private arrangement nobody supervises.
• The Works Department will not grant a building permit. To apply for one you must prove ownership of a determined piece of real estate, and a share is not that. If the property also lies outside the urban boundary, the prohibition in article 55 is added on top.
• Without a permit there is no final approval, and without final approval the house does not exist for legal purposes. Nor can it be brought under the ley del mono amnesty, because that route assumes land on which building is allowed.
• Water and electricity stay precarious. A definitive connection is applied for with title and tax roll. What ends up being built are collective connections or spurs from somebody else’s meter, with the neighbour disputes that brings.
• There is no mortgage and no housing subsidy. No bank takes a mortgage over a share in a property subdivided in fact, and no housing programme accepts that title.
• Selling becomes almost impossible. The only possible buyer is another cash purchaser who accepts the same problem, and he will pay far below the market value of a site with proper title.
• A neighbour may build where your lot used to be. Nothing in the registration says that piece is yours. If another co owner builds there, you have no claim in rem over that piece, because your right is over the whole.

Access problems pile on top. Many of these subdivisions are served by a strip the seller drew on the plan and never constituted as an easement, so the sites at the back end up with no legal access to a public road. If you are buying from abroad, it is also worth reading our guide on how to buy property in Chile as a foreigner and the one on how to avoid real estate scams in Patagonia.

Article 1344: why your lot may end up belonging to someone else

This is the risk almost nobody explains at the notary’s table. Article 1344 of the Civil Code provides that, once the division is made, each party is deemed to have held exclusively the object allotted to him and never to have had any right in the others. Division does not distribute forwards: it declares backwards, as though from day one that lot had belonged to whoever ended up receiving it.

The second paragraph draws the conclusion: if one of the co assignees disposed of a thing that the division allots to another, the matter proceeds as in the sale of another person’s property. Applied to a shares and rights subdivision it means this: if tomorrow the community is divided and the piece where you built is allotted to another co owner, the purchase you made over that piece becomes a sale of another person’s property, unenforceable against the person to whom it was allotted.

This is not a textbook hypothesis. It is the natural scenario of any community of twenty people who never met each other, where it is enough for one of them to die, divorce, go bankrupt or be subject to enforcement for the informal balance to break.

Division is a time bomb, not a theoretical threat

Article 1317 of the Civil Code provides that none of the co assignees is obliged to remain in undivided ownership and that division may always be sought. An agreement not to seek it is capped at five years, renewable, and outside that case the right does not lapse. Any of the co owners can trigger it. So can a creditor who attaches the share of one of them, which in practice is the most frequent entry point.

And here the underlying problem appears. An arbitrator cannot settle the matter by giving each co owner his 250 square metre site, because Decree Law 3,516 does not allow those lots to be created. Two routes remain: one of the co owners keeps the whole property and pays the others what their shares are worth, or the property is auctioned entire and the money is split according to the registered percentages.

In both scenarios the house you built gives you no right to stay. It gives you a claim for improvements against the community, argued inside the same proceedings and almost never paid at replacement value. That is why, when a client tells us he has lived there quietly for fifteen years, the honest answer is that the quiet of a de facto community lasts exactly until one of the twenty has a problem.

What can be fixed: Law 20,234

So much for the diagnosis. The good news is that the State recognised the size of the problem and created a special procedure for these settlements. It is Law 20,234, which establishes a simplified procedure for the regularisation of subdivisions, amended by Law 21,477 of August 2022 and later by Law 21,585.

It is not a procedure that can be invoked at any time or for any subdivision. Circular DDU 509 of the Ministry of Housing and Urban Development sets out the admissibility conditions, and they are worth measuring before spending a peso.

Where the subdivision qualifies, the outcome is concrete: final approval of the urbanisation works is obtained and the areas set aside for roads and green space pass into public ownership. Only then can an individual title for each site be reached, which is what the buyer thought he was purchasing on day one.

The rural filter is what decides. If your plot lies outside the urban boundary and the settlement does not fit one of the article 55 exceptions, Law 20,234 will not save it however old the subdivision may be. That has to be known before, not after, commissioning plans and surveys.

The other routes, where Law 20,234 does not apply

Subdividing the property properly

If the property has enough area to generate lots of 0.5 hectares, the route is formal subdivision, with a plan, review by the authorised third party and a certificate from the Agriculture and Livestock Service. You can review the exact requirements to subdivide farmland before commissioning any survey work.

Where the transfer is to a first degree relative there is also the exception in Law 19,807, known as the Sabag Act, which allows lots of between 500 and 1,000 square metres under strict requirements. The Sabag Act test tells you in two minutes whether your case fits.

Division with allotment

If the co owners agree and the property admits lots of the minimum area, the community can be brought to an end by division and each one allotted his part, either by agreement in a public deed or before an arbitrator. It is the clean exit, but it requires the geometry of the lots to be lawful, which is exactly what is missing in a subdivision of 250 square metre sites.

Claims against the seller

A buyer who was misled is not without tools. Depending on how the deal was presented, there is room for rescission of the contract with damages, annulment for mistake or fraud, and a criminal complaint under article 138. These are civil proceedings with their own limitation periods, so they are worth reviewing as soon as the problem is spotted and not years later.

Regularisation under Decree Law 2,695, with care

Regularisation of small rural holdings is processed before the Ministry of National Assets and requires material possession for the statutory period, as well as compliance with the valuation caps. It is not a shortcut to create a lot that the subdivision rules do not allow, and applications arising from irregular subdivisions are frequently rejected. Before spending on that procedure it is worth reviewing how the courts have been ruling in this area and commissioning a title search over the whole property.

What to check before signing

If you have not bought yet, this list takes an afternoon and avoids the entire problem.

• Current ownership certificate for the whole property, not for the lot. Request it yourself at the Registry using the page and number, and see how many people it is in the name of.
• Certificate of mortgages, encumbrances and prohibitions, again for the whole property. A prior mortgage affects every share, including yours.
• Tax roll. If there is a single roll for the whole tract, there are no lots. If you are shown a different roll per site, ask for the resolution that authorised the subdivision.
• Municipal prior information certificate. It states whether the land is inside or outside the urban boundary, which is what decides which rules apply.
• The plan, with a name and a number. Ask which authority approved it and under which resolution. If the answer is that a surveyor drew it, that plan creates no lots.
• How many co owners are registered. Every share sold adds one more person entitled to demand division of the entire property.
• The promise to regularise later. Ask for it in writing, with a deadline, a termination clause and a refund. If the seller refuses, you already have your answer.
• Access. Check whether the road you use is constituted as an easement in a registered deed, or whether it is only a strip drawn on a plan.

If you have already bought

Order matters, because each step depends on the previous one. First, establish exactly what your registration and the property’s registration say: how many co owners there are, what encumbrances exist and since when. Second, determine whether the settlement qualifies under Law 20,234, measuring age, occupation and location. Third, if it does not qualify, assess whether the property admits a formal subdivision or a division with allotment. And in parallel, review the limitation periods on claims against the seller, which run from before you knew about the problem.

What does not help is sitting still and waiting for the situation to settle by itself. De facto communities do not tidy themselves up over time: they grow, they add heirs and creditors, and every new co owner is one more key that can open the door to division.

Frequently asked questions about shares and rights

Is it illegal to buy shares and rights?

Buying a share is perfectly lawful and article 1812 of the Civil Code expressly authorises it. What the law punishes is something else: constituting communities in order to form new settlements without urbanisation or authorisation, which is the offence in article 138 of the General Urban Planning and Construction Act. The buyer does not commit that offence. The problem is not whether your purchase is lawful, it is that what you bought is not a site.

They told me it gets regularised later. Is that true?

It depends on facts that can be verified before signing. If the subdivision came into existence after 31 December 2018, Law 20,234 does not apply. If it lies outside the urban boundary and does not fit an article 55 exception, it does not apply either. And if the property cannot yield 5,000 square metre lots, formal subdivision is ruled out. When all three doors are shut, the promise to regularise has no basis, however good the faith of the person making it.

Is the plan the seller gave me worth anything?

It is worth something as evidence of what you were offered, and that has value in a claim against the seller. It is worth nothing for proving ownership of the lot, applying for a permit or registering anything, because it was never approved by the competent authority. Keep it together with the sale listing, the payment receipts and your messages with the seller.

Can I put the water and electricity in my name?

For a definitive connection the utilities require proof of ownership over a determined property and, depending on the case, a feasibility certificate from the Works Department. A share does not meet that. What usually gets built are collective connections in the name of the community, or spurs from a third party meter, which work while relations between neighbours are good and collapse when they are not.

I built a house. Do I lose it?

You do not lose it overnight, but your position is weaker than it looks. While the community exists, you occupy on the tolerance of the others. If a division takes place and the piece is allotted to another co owner, what remains is a claim for improvements within those same proceedings, not a right to stay. Separately, building without a permit can carry municipal penalties of its own, and the fine is set as a share of the cost of the works.

Can I get my money back?

It is possible depending on how the transaction was presented and what was put in writing. The routes are rescission with damages and annulment for mistake or fraud, and in some cases a criminal complaint. All of them have time limits, and all of them depend on the evidence: deed, plan, listings, transfers and conversations. The fuller the file, the better the position.

What is my share worth if I want out?

Considerably less than a site with proper title, and that difference is precisely the cost of the problem. Whoever buys a share knows he cannot build with a permit, cannot mortgage and is exposed to division, so he discounts all of that from the price. The way to recover that value is not to look for a better buyer, it is to fix the title.

How we handle it

We always start in the same place: a title search over the whole property, not over the lot. That shows how many co owners there are, what encumbrances weigh on the tract, since when the community has existed and whether there was ever an attempt at subdivision. With that on the table it becomes possible to say which route is genuinely open.

From there the work depends on the diagnosis: regularisation under Law 20,234 where the settlement qualifies, subdivision of the property where the area allows it, title regularisation where the possession requirements are met, and a civil claim against the seller where there was deception. The survey and the plan are produced by our own team, so there are no separate offices to coordinate. If what you need first is a sense of scale, the regularisation cost calculator gives a reference figure.

What we do not do is promise an outcome before seeing the papers. Send us the deed, the current ownership certificate for the property and the plan you were given, and we will tell you which route you have, how long it takes and what depends on third parties. We work in Spanish and in English, so distance is not an obstacle.
