Can a property be sold without an heir's signature?

As a general rule, no: a voluntary sale before a notary requires the consent of every co-heir. But one heir's refusal does not block the sale forever. Chilean law provides for partition proceedings, a compulsory judicial route in which the signature of the heir who objects or cannot be found stops being necessary, because the authority of the court supplies it instead. One co-owner's opposition does not prevent the sale. It just changes the path to get there.

We recommend reviewing our main guide to the posesión efectiva, the Chilean grant of probate.

The situation facing estates is often marked by deep emotional and financial strain. The central source of frustration is having a buyer ready to purchase the property at market price, only for a single heir to block the deal. In civil litigation practice, this kind of obstruction rarely rests on legitimate legal grounds or investment strategy. It is usually driven by old family grudges, personal stubbornness, or, frequently, by the fact that the objecting heir is living in the inherited property without paying for it. This effective seizure of the family estate freezes the economic value of the assets, denies the other heirs access to their rightful share, and often exposes the property to gradual deterioration and to mounting debts for property tax or common expenses.

Faced with this imbalance, civil law does not allow an estate to remain locked up forever. By combining partition proceedings with firm negotiation, it is legally possible to unlock the inheritance. Once the conflict moves into the courts, the signature of the heir blocking the deal is replaced by that of a court appointed arbitrator handling the partition. The arbitrator can order a valuation of the property, put it up for auction if it cannot be conveniently divided, and distribute the proceeds among the co-heirs. If handing over the property requires forcibly removing an occupant, that enforcement has to be sought from the ordinary courts.

The unanimity rule: why the notary requires every signature

To unpack the legal reasons that let a single person freeze a high value property transaction, it is essential to look at the nature of the "comunidad hereditaria", the estate held in co-ownership pending division. The moment the deceased dies, and strictly in line with the rules governing the opening of a succession, a co-ownership over the transmissible estate automatically arises whenever there is more than one heir. Article 2304 of the Chilean Civil Code defines this situation by stating that co-ownership of a universal or specific thing, between two or more people, none of whom has formed a company or entered into any other agreement over that same thing, amounts to a form of quasi-contract.

At this preliminary stage, civil law scholarship stresses that the heirs do not acquire ownership of a specific, physical portion of the property. They do not own a particular room or a defined hectare of land. Instead, each holds an ideal, abstract, percentage share, for example 25% or 33.3%, over the legal universality of the estate. This co-ownership is conceived under Chilean law, heavily influenced by Roman law, as a transitional, incidental and inherently unstable state of affairs, meant to come to an end once the common estate is divided.

For the heirs to gain the legal capacity to dispose of or transfer inherited real property, the law requires strict compliance with article 688 of the Civil Code, which sets out a strict chain of registrations with the relevant Conservador de Bienes Raíces (the Chilean property registry). This chain of registrations acts as a filter of legality protecting property transactions:

Registration under the law (art. 688 CC)	Competent authority	Legal effect
1. Posesión efectiva and the will	Registro Nacional de Posesiones Efectivas, if granted by the Civil Registry; if granted by a court, the Conservador de Bienes Raíces for the district where it was issued, together with the will.	Enables the heirs to act. It does not grant the power to dispose of real property.
2. Special inheritance registration	Property Registry at the local Conservador de Bienes Raíces.	Registers the property in the name of all the heirs. It allows the property to be disposed of, but requires the heirs to act "de consuno" (jointly, that is, unanimously).
3. Registration of the award	Property Registry at the local Conservador de Bienes Raíces.	Vests exclusive ownership in a single heir after the partition, allowing them to sell individually.

The practical conflict inevitably arises at the second stage, the special inheritance registration. From that point on, the co-heirs manage to register the property in their name, but the law imposes a strict condition on any act of disposal: they must act "de consuno". This legal expression means that any act transferring ownership of the shared property requires the unanimous will of every co-owner.

It is precisely this unanimity requirement that underlies the preventive approach taken by notaries public, Conservadores de Bienes Raíces and banks. When trying to execute a public deed for a voluntary sale, the notary, acting as a certifying public official, will require the appearance, identification and signature of one hundred percent of the registered title holders. Likewise, if the third party interested in buying the property is financing the deal with a mortgage, the bank's legal department will carry out a thorough title study. Without a single heir's signature, the bank will reject the title: as regards the share of the heir who did not sign, the transaction is a sale of another person's property, which is valid between the parties but does not affect the rights of the co-owner who did not take part, so the buyer does not acquire the whole property. So if an heir refuses to sign or cannot be found, the direct sale cannot go ahead. An heir who is a minor is a different case: their legal representative signs for them, with prior authorisation from a judge who has reviewed the case, and if the representative is a guardian, the law also requires the sale to take place at public auction.

The legal way out: no one is obliged to remain in co-ownership

Faced with the absolute deadlock the unanimity rule creates, the legislature has provided a doctrinal, procedural mechanism of last resort to safeguard property rights and the free circulation of wealth. This guiding principle is set out in article 1317 of the Chilean Civil Code, in terms that are mandatory and categorical: "None of the co-heirs of a universal or specific thing shall be obliged to remain in co-ownership; partition of the assigned property may always be requested, provided the co-heirs have not agreed otherwise".

A close reading of this provision shows that the right to seek partition carries three formidable procedural features: it cannot be waived, it can be exercised absolutely, and it never lapses through the passage of time. This guarantees that no co-owner, however small their share, can be forced to keep their capital locked up. The heirs may agree not to divide for a maximum of five years, and once that term ends the agreement can be renewed. In addition, an heir whose entitlement is subject to a condition precedent cannot request partition while the condition is pending.

To carry out this separation of assets, the Chilean judicial system provides for partition proceedings, a complex legal process whose purpose is to wind up the estate held in co-ownership, value the assets, deduct debts left by the will or the estate, and allocate what remains. Given the arithmetical, technical nature of this procedure, the law takes the substance of the matter away from ordinary civil judges and hands it to a court appointed arbitrator, who must by law be a qualified practising lawyer, and who as a general rule acts as an arbitrator at law.

The procedure unfolds in successive stages, each one closing off the last. It begins with filing a claim before the competent civil court, asking it to summon every co-heir to a hearing to appoint the arbitrator. In highly contentious cases, a failure to attend or to agree at that hearing allows the civil judge to appoint the arbitrator unilaterally. Once the arbitrator accepts the role and is sworn in, the management of the shared assets and decisions about what happens to them are settled before the arbitrator.

During the arbitration, the arbitrator will call hearings to set the rules for the procedure. If the property, for example a house or an apartment, cannot be divided, or would lose value if divided, the arbitrator must declare this and put it up for bidding: the co-heirs can bid for it, and any of them can ask for outside bidders to be admitted. The minimum price is set by expert valuation or, in certain cases, by agreement between the parties, and the auction is announced through notices in a newspaper.

This mechanism culminates in the public auction, an act that finally puts an end to the difficult heir's resistance. Once the property is awarded to the highest bidder, it is the arbitrator who, acting as the compulsory legal representative of every co-heir, signs the public deed of sale in favour of the successful bidder. Finally, the arbitrator issues a complex final ruling known as the "laudo y ordenata". The laudo resolves every legal dispute submitted to the arbitration, while the ordenata sets out the precise mathematical calculations of the liquidation, fixing the exact monetary share owed to each party after the legal deductions. The real right to the inheritance is thereby turned into cash.

Alternatives before the auction: legal pressure and negotiation

While the machinery of partition proceedings offers a definitive, guaranteed solution, carrying the arbitration all the way through to public auction is not always the financially best option for the estate. Taking a property to auction has two significant downsides. First, the fees of the arbitrator, of the court clerk who acts alongside them and of the valuers are a significant cost, set case by case, which as a common cost of the partition is borne by all the parties in proportion to their shares. Second, the price obtained at a forced auction tends to fall below market or retail value, attracting mainly property investors chasing a quick margin.

Given these economic considerations, strategic legal counsel, of the kind developed by firms that specialise in this area, uses the filing of a partition claim not as an inevitable end point, but as a powerful tactical pressure tool. Often, the heir blocking the sale assumes the dispute will never reach the courts. However, once that heir is formally served by a court process server, summoned to appear before a court, and realises the property will inevitably be auctioned off, causing a direct financial loss through costs and arbitration fees, their position often changes radically. Faced with that prospect, many choose to sign a voluntary sale, which is usually the most sensible outcome for everyone.

It is advisable to pair the partition with a claim to end the free use of the shared property, set out in article 655 of the Code of Civil Procedure. At its root, the family conflict usually comes down to the objecting heir making exclusive use of the property, enjoying its benefit without paying anything to the community. The law is clear: no co-owner can claim exclusive use of an asset that belongs to everyone, unless they can show a "special title" that legally entitles them to do so.

Impact of the claim to end free use

Legal and financial effect	Description
De facto situation (no claim filed)	The occupant lives there for free, stalling any voluntary process indefinitely.
Filing the claim (art. 655 Code of Civil Procedure)	The judge must order an end to the free use. The occupant's comfortable status quo is broken.
Setting a rental charge	If the claim expressly asks for it, the court can set a monthly rent the occupant must pay to the other co-heirs; if it is not requested, the court cannot set one of its own accord.
Deductions at partition	The unpaid rent accrues as a debt to the community and is deducted directly from the occupant's share in the ordenata.

By invoking article 655 of the Code of Civil Procedure, the court orders an end to the free use, meaning that if the defiant heir wants to keep living in the house while the partition proceedings run their course and the claim asked for a rent to be set, they have to pay it monthly to the other co-heirs. The looming threat of auction, combined with turning their free housing into an accumulating financial liability, creates the ideal setting to force a negotiation and unlock the sale of the property on the most favourable terms for the estate.

Sometimes the heir who will not sign holds out because another heir received more during life. That claim has a legal route of its own, which we explain in inheritance given away before death.

Once the posesión efectiva has been granted, what is still missing before you can sell is covered in selling an inherited property in Chile.

Common questions about heirs who will not sign

Because the succession process is so shaped by family dynamics and a lack of technical knowledge, it tends to be surrounded by mistaken legal assumptions. Addressing these concerns with legal rigour is essential to avoid the estate's management grinding to a halt.

What happens if the heir who will not sign cannot be found or is outside Chile?

Not knowing an heir's whereabouts, their long term residence abroad, or their simply having dropped out of family life are not insurmountable obstacles to selling the property. The legislature made clear that the majority's property rights cannot be held hostage to one person's personal circumstances. If the heir lives abroad at a known address, they are served there through an international letter of request, which lengthens the timetable but does not halt the case. If their residence is hard to determine, article 54 of the Code of Civil Procedure allows service by public notice. After showing the court that reasonable search steps were taken (requests to Carabineros, the Civil Registry, the Investigative Police, and so on) without success, the judge will order extracts of the partition claim to be published in widely circulated newspapers and in the Official Gazette. These publications create a legal presumption that the heir has been properly served, safeguarding due process.

If the heir who has been served does not appear, the case goes ahead in their absence. If, in addition, their whereabouts are unknown, they left no representative and their lack of contact is causing harm, the court can be asked to appoint a curator of the absent person's property. The role goes preferably to their spouse or relatives, in the order set by law, and the public defender must be heard on the appointment. The curator needs court authorisation to request the partition, and a partition in which an absent heir without a representative has an interest must, once completed, be submitted to the court for approval. This curator formally represents the absent heir at every hearing in the arbitration, allowing the auction, the liquidation and the deposit of the absent heir's share to go ahead in full compliance with the law, bringing the partition to a successful close.

Can I sell my percentage (assignment of inheritance rights) to a third party?

When a succession dispute drags on, it is common for some heirs to try to sell their share and walk away from the litigation. Selling that percentage is lawful, and it is done through an assignment of inheritance rights, which, when made by way of sale, must be executed as a public deed; its effects are governed by articles 1909 and 1910 of the Civil Code. Through this instrument, the assigning heir transfers their right in the universality of the estate to a third party assignee, who then steps into exactly the same legal position within the estate's co-ownership.

From a real estate and financial standpoint, however, it is crucial to flag the risks of this transaction. Under article 1909, someone who assigns their inheritance right for value, without specifying particular assets, "is answerable only for their status as heir". The assignee does not acquire possession or ownership of a wall, a room, or any physical percentage of the property. They acquire an abstract share subject to however the partition proceedings turn out. On the other hand, trying to assign the inheritance right by tying it specifically to the property in question moves into much murkier ground. The prevailing case law and legal scholarship hold that if the property is not later awarded to the seller in the partition, the third party buyer ends up facing a "sale of another person's property", one that cannot be enforced against the true titleholder.

In market practice, the few investors willing to put capital into an assignment of inheritance rights demand a steep discount against the commercial value of the share, paying well below its real worth, because of the legal risk and the burden of having to bear the cost and time of partition proceedings against the remaining heirs. As a result, while it is a valid legal way out, it is the least profitable and most costly option for the heir's finances.

It is worth not confusing two transactions that, in practice, get offered under the same name. The assignment of inheritance rights under article 1909 covers the universality of the estate, not a specific asset. Selling a share in a property that is already registered in the name of all the co-heirs is a different matter, authorised under article 1812 of the Civil Code. Each is registered differently, and each carries its own version of the risk set out in article 1344. What is actually transferred when a share is sold, and how far that risk reaches, is explained in our guide to shares and rights in an undivided estate.

Does the heir who will not sign lose their share of the money after the case?

One of the most widespread assumptions has no basis whatsoever in Chilean civil law: the idea that whoever blocks the sale will be stripped of, or lose, their inheritance right as a penalty. Civil property law does not work by imposing punitive forfeitures on ownership lawfully acquired. When the partition proceedings conclude, the arbitrator issues the "ordenata". This document is the estate's accounting record, setting out the detailed calculation of how the funds raised at auction are distributed.

The gross proceeds are subject to mandatory deductions: the estate's general charges, unpaid estate debts, the offsetting of the co-heir's personal debts to the community (such as the rent accrued for ending the free use), and the pro rata share of the arbitration's costs and fees. Once the divisible net estate is determined, the arbitrator calculates the exact fraction owed to the dissenting heir. Their money is not lost or confiscated: that amount remains available to them, or to their curator if one has been appointed. The only real penalty the difficult co-heir suffers is the direct financial loss of having forced an auction, which sells at lower prices, and having funded a costly arbitration that could have been avoided through sensible negotiation.

Before any of this, the estate has to be registered

A sequencing mistake stalls many of these cases before they even start. You cannot sell what is not yet registered in the heirs' names, and without those registrations, whatever is awarded or auctioned in a partition cannot be registered either. Many families only discover this at the notary's office, once they already have a buyer.

1. The posesión efectiva, which establishes who the heirs are. It is an administrative procedure, not a lawsuit, and it does not require everyone to agree: any heir can request it.
2. The declaration before the Servicio de Impuestos Internos (the Chilean tax authority) and payment of, or exemption from, inheritance tax.
3. The special inheritance registration at the Conservador, which is what puts the property in the name of all the heirs. It is the step most people skip, and without it the property keeps appearing under the deceased's name.
4. Only at that point does a registered estate co-ownership exist, and only then does each co-heir's signature start to matter, or not.

The good news is that none of these three steps requires unanimity. The heir who objects can block a voluntary sale, but cannot stop the succession from being processed.

What you can charge the heir occupying the property

This is the question that stirs up the most frustration and confusion, and there is more room to act than people think.

The honest strategy. Going all the way to auction is the worst financial outcome for everyone, because a judicially auctioned property rarely reaches the value of an ordinary sale, and on top of that the arbitrator's fees have to be paid. That is why a partition claim works best as leverage rather than as an end goal: once the objecting co-owner understands that the property will be liquidated regardless, that they will pay their share too, and that they will end up with less, it is common for the case to end in a voluntary sale at market price. How that procedure works on the inside is covered in our guide to partition proceedings.

How we handle it

The first step is checking the actual state of the succession, because a large share of these cases get stuck not because of the sibling who objects, but because of a pending step nobody ever completed. We check that with a title study and by reviewing the posesión efectiva and the special inheritance registration. It is the cheapest part of the process, and the one that most often unblocks it without any litigation.

Once the community is registered, we assess whether the case can close by agreement or whether it needs to go into partition proceedings. When litigation is warranted, we bring it together with the claim over exclusive use, because the two together change the objecting co-owner's calculation much faster than partition alone.

If a rural parcel is among the assets, awarding it in lots has to respect the minimum size set by decree law 3.516, and in that case the survey and subdivision work is handled by our own team. And if an heir lives outside Chile, they can grant power of attorney at the Chilean consulate in their city without travelling, as we explain in our international section.

Send us the property's current certificate of title, and tell us how many heirs there are, who is occupying the property, and since when. With that, we will tell you whether your case can be resolved with a pending step, whether it is worth negotiating once the claim has been filed, and what can be recovered for the exclusive use.
