A deed, a percentage and a fenced plot do not answer the underlying question: what was actually acquired? This analysis separates the reach of an assignment of rights, its use as a basis for regularizing title before Bienes Nacionales, and the limits an irregular subdivision imposes.

The advert offers plots with easy payment terms. At the notary’s office an assignment of rights is signed: the buyer acquires a percentage of a larger property, with a clause referring to “lot 14” on a plan and another assuring that, after five years, the title can be regularized before Bienes Nacionales. Then come the fence, the house and the years, until a subsidy, a loan or an inheritance forces the question: what exactly was bought?

Bienes Nacionales knows that clause. On its page on irregular subdivisions it says it has seen deeds in which the developer and assignor of rights promises regularization within that period, and it answers that this is false: in an irregular settlement it regularizes only by way of exception, when the requirements of special laws are met. In August, while promoting its campaign in the Biobío region, the Ministry stressed that completing five years of possession does not automatically make anyone an owner, and the regional secretary explained that in the El Edén subdivision, in Punta de Parra (Tomé), where plots were bought as rights and shares, an emergency regularization had to be opened after the wildfires.

The opposite is not true either: the assignment is not worthless paper, and the law gives it effects. The mistake is answering in one go three questions that have to be answered separately:

  1. What does the deed transfer?
  2. Does that deed help regularize title before Bienes Nacionales?
  3. What changes if the land is in an irregular subdivision?

The guides on the regularization procedure, on opposing a regularization and on Ministerial Order No. 2/2026 are already published; this analysis deals with what happens before the file is opened.

1. What does the deed transfer?

Article 1812 of the Civil Code (Código Civil) allows each co-owner to sell their share without the consent of the others. That is what an assignment of rights transfers: an undivided share of the whole property. The area, lot number or plan the deed may add does not turn it into ownership of a portion, which among co-owners is defined in the partition (Article 1317). And allocating a lot in that partition runs into the rules the subdivision sidestepped: Article 136 of the General Law on Urban Planning and Construction (Ley General de Urbanismo y Construcciones) (LGUC) bars recording partial transfers or allocations of land without a certificate of urbanization from the Municipal Works Department.

The share, moreover, is only transferred by recording it with the Real Estate Registrar (Conservador de Bienes Raíces) (Article 686 of the Civil Code). Without that record, the buyer holds a contract with the seller, not the right.

That record is hard to obtain today. Law No. 21,477 (Ley N° 21.477), of August 2022, added to Law No. 20,234 (Ley N° 20.234) an Article 15 that bars notaries from authorizing, and requires registrars to reject, titles that may lead to a subdivision or split of land without complying with the planning rules. A single sign is enough, and the law lists, among others:

  • several partial transfers of rights over the same land;
  • a reference to a specific area or location within the property;
  • an allusion to settlement programs or future allocations;
  • a plan or list of sites or lots;
  • the lack of the authorizations under Article 55 of the LGUC or of the certificate of urbanization.

The typical subdivision deed ticks almost every box. The presumption can be rebutted, for example by proving that the rights come from a partition of an estate or from the winding up of a marital community of property.

The same Article 136 bars the developer from selling or forming co-ownerships to create settlements without urbanizing, and Article 138 punishes those acts with a prison sentence ranging from presidio menor in its maximum degree to presidio mayor in its minimum degree. That list includes the occupant and the possessor, something anyone thinking of reselling their plot the same way should bear in mind.

2. Does that deed help regularize title before Bienes Nacionales?

It does, but for something narrow. Decree Law No. 2,695 (D.L. 2.695) allows anyone in material possession of real property without a registered title, with a tax appraisal of up to 1,000 UTM (monthly tax units), to obtain the status of regular possessor and then ownership by prescription. It requires continuous and exclusive possession, without violence or concealment, for at least five years.

The assignment comes in through Article 3, which allows the applicant to add the possession of their predecessors where there is an apparent title, and expressly mentions “the acquisition of improvements or of rights and shares in the property, whether by public or private instrument”. That is why Bienes Nacionales lists it among the imperfect titles the procedure can cure.

But adding is allowed only if the property is not part of a larger registered property, and a plot carved out of a registered property is exactly that. In a subdivision, then, the seller’s years do not count: the period runs from the moment the buyer took possession of the land. And where adding is allowed it comes at a cost, because under Article 16 the mortgages, encumbrances and attachments of the predecessors whose possession was added continue to burden the property.

Two points are reviewed with the titles in hand:

  • Exclusive possession. The decree requires it and the deed speaks of co-ownership. It is proven through positive acts such as enclosures, buildings or plantings (Article 925 of the Civil Code).
  • Recorded share. If the assignment was recorded, the buyer already holds a registered title, even if it is to a share and not to the lot, and the decree is designed for those who lack one.

Article 19 works in the buyer’s favor. Anyone who sold or promised to sell to them, even by private instrument, and received money on account of the price cannot oppose on the basis of their registered title, and neither can someone who is merely a co-owner. Both are left with a claim for monetary compensation.

3. What changes if the land is in an irregular subdivision?

A second problem is added, one the decree does not solve. The decree answers the question of title: who owns what? The subdivision raises another, about planning: is splitting the land lawful? Bienes Nacionales defines an irregular subdivision as a split of land without a provisional or final municipal permit. In rural areas, moreover, Decree Law No. 3,516 (DL N° 3.516) only allows free division into lots of at least 0.5 physical hectares, and Article 55 of the LGUC prohibits subdividing outside urban limits to form settlements.

Three requirements follow:

  • Acceptance of the urbanization works. If the land is in an irregular subdivision, Bienes Nacionales requires the certificate of final acceptance, and Article 4 of Law No. 20,234 only allows the title to be granted once the urbanization works of the sector have been accepted. The exception is settlements under a Housing and Urban Development Service (SERVIU) with a strategy to settle residents in place, where provisional acceptance is enough.
  • Cut-off date. The simplified procedure of the subdivisions law covers settlements that physically existed before December 31, 2018 or that are included in the 2019 cadastre of informal camps, and it is available until December 31, 2030. It is collective: it is requested before the Municipal Works Department by interested parties representing at least 30 percent of the permanent residents, or by the municipality or the SERVIU, among others. A later subdivision falls outside it.
  • Prior information certificate. Article 5 of the decree requires it to be submitted, issued by the Municipal Works Department for regularization purposes (certificado de informaciones previas), and orders it to be taken into account when approving or rejecting the application. That is how the planning problem enters the file.

In La Araucanía the first thing to ask is whether the land is indigenous. Article 8 of the decree excludes it, and Article 13 of Law No. 19,253 (Ley N° 19.253) prohibits selling, encumbering or acquiring it by prescription except between indigenous communities or persons of the same ethnic group, on pain of absolute nullity.

What should be checked before paying or filing the application?

RecordWhere to get itWhat for
The deed or instrument signedNotary’s officeTo see whether it transfers a share or mentions a lot, a plan or a promise of regularization
Current ownership record of the propertyReal Estate RegistrarTo learn who the registered owner is, how many assignments exist and whether the buyer’s was recorded

Indigenous status of the landCONADI Public Registry of Indigenous LandsTo rule out the exclusion and nullity
Evidence of one’s own possessionUtility bills, property tax payments, photographs, neighborsTo establish when the period started running

On the same warning page, Bienes Nacionales publishes two checklists for buyers, one urban and one rural, and warns that they do not guarantee title.

What if you have already signed?

  • Gather the deed, the payment receipts and the evidence of when you took possession of the land and what you have done on it.
  • With the current ownership record and the prior information certificate you will know whether the path is an individual application, a collective regularization of the subdivision or a claim against the seller, civil and, depending on the facts, criminal. The Ministry also runs a channel for reporting irregular subdivisions.
  • Do not pay the seller to “handle the title”: the application is filed with the regional office (SEREMI) and decided by the Ministry.

The procedure does not require a lawyer and can be free of charge for the most vulnerable 40% of the Social Household Registry (Registro Social de Hogares). If the records are in order and the land is not in an irregular subdivision, you can file it yourself. When there is an assignment over a larger property or a subdivision involved, it is worth reviewing the titles before paying or filing.

Frequently asked questions

Does buying rights and shares in a piece of land make me the owner of a plot?

Not on its own. What is acquired is a share of the whole property, and each co-owner's specific portion is defined in the partition. In addition, the share is transferred by recording it with the Real Estate Registrar (Conservador de Bienes Raíces): without that, the buyer only holds a contract with the seller.

Can land bought through an assignment of rights be regularized before Bienes Nacionales?

It can be. Bienes Nacionales lists the assignment of rights among the imperfect titles that title regularization can cure, but the requirements of Decree Law No. 2,695 must be met: continuous and exclusive material possession for at least five years, a tax appraisal of up to 1,000 UTM and, in an irregular subdivision, acceptance of the urbanization works.

Is it true that Bienes Nacionales issues the title after five years?

No. The Ministry warns that it has seen deeds with that promise and calls it false: in an irregular settlement it regularizes only by way of exception. The promise binds the seller, not the Ministry.

Can I add the years the seller held the land?

Only if the plot is not part of a larger registered property, under Article 3 of the decree. Where adding is allowed, the seller's mortgages and attachments continue to encumber the property.
