Sale of Co-Ownership Share Chile

Sale of Co-Ownership Share Chile (Compraventa de Derechos Pro Indiviso) is a property transfer contract governed by the Código Civil — specifically Articles 1812 through 1817 on the sale of things belonging to several persons, and Article 2304 on comunidad (co-ownership) — by which one or more copropietarios (co-owners) sell their undivided interest (cuota indivisa or derechos pro indiviso) in a jointly-owned property (bien raíz or bien mueble) to a buyer (comprador), who may be a co-owner (comunero) or a third party (tercero ajeno a la comunidad).

Comunidad in Chilean law — regulated under Título XXXIV of the Código Civil (Articles 2304–2313) — arises when two or more persons hold ownership rights over an undivided property without any formal partition (partición) having occurred. Common sources of comunidad include intestate succession (herencia intestada) where multiple heirs inherit a property jointly under the Código Civil's succession rules (Title III of Book III), dissolution of a sociedad conyugal (matrimonial property regime) where both spouses acquire undivided rights to community property, joint purchase (compra conjunta) where two or more buyers acquire a single property collectively, and failed partición proceedings.

Article 1812 of the Código Civil establishes that a copropietario may freely sell their pro indiviso share (cuota) without the consent of the other comuneros — the general rule of free alienability of property rights. However, Articles 1814 through 1817 impose important restrictions and protective mechanisms. Article 1815 provides that the sale of cosa ajena (property of another) is valid but subject to the rights of the true owner — relevant when a copropietario purports to sell more than their actual cuota. Article 1817 establishes the critical derecho de retracto de comuneros (co-owners' right of first refusal): if a copropietario sells their cuota to a third party (not a fellow comunero), the other comuneros may exercise the retracto within a statutory period to acquire the sold cuota at the same price and conditions agreed between the seller and the third-party buyer, effectively substituting themselves in the sale.

For real property (bienes raíces), the Compraventa de Derechos Pro Indiviso must comply with all formal requirements applicable to real estate sales in Chile: execution by escritura pública (public deed) before a Notario Público as required by Código Civil Article 1801 inciso 2; inscription (inscripción) in the Registro de Propiedad of the Conservador de Bienes Raíces (CBR) competent for the commune where the property is located, as required by Código Civil Article 686 for the transfer of dominion (tradición); and payment of applicable taxes — the transfer may be subject to impuesto de herencia (inheritance tax) if the cuota was acquired through succession, or to the impuesto global complementario / impuesto a la renta on capital gains under the LIR if sold by a persona natural not classified as a real estate developer.

The Servicio de Impuestos Internos (SII) requires that the notarial deed of Compraventa de Derechos Pro Indiviso include the parties' RUT (Rol Único Tributario) and comply with the SII's reporting obligations for real property transactions. The SII also assesses the fiscal value (avalúo fiscal) of the property for transaction tax purposes through the Dirección de Avaluaciones. For inherited properties, the Servicio de Registro Civil e Identificación processes the posesión efectiva (grant of probate) that formally recognizes the heirs as comuneros before any pro indiviso sale can proceed.

Pro indiviso sales of agricultural land (predios agrícolas) may require additional compliance with the Ley N° 18.755 on the Servicio Agrícola y Ganadero (SAG) if the transaction involves properties subject to agricultural restrictions. Sales of community shares in properties located within condominios are additionally governed by Ley N° 21.442 on Copropiedad Inmobiliaria, and the buyer must comply with the reglamento de copropiedad upon acquiring the cuota.

A Sale of Co-Ownership Share Chile is required whenever a copropietario wishes to transfer their undivided interest (cuota pro indiviso) in a jointly-owned property to another person — whether a fellow comunero or a third party — without first completing a formal partición of the entire community property.

The most common scenario involves inherited real estate (herencia inmobiliaria): when a person dies leaving real property in Chile without a will (sucesión intestada) or with a will that divides the estate among multiple heirs, the heirs become comuneros of the inherited property upon the grant of posesión efectiva issued by the Servicio de Registro Civil e Identificación. If one heir wishes to liquidate their share of the inherited property without the cooperation of the other heirs — who may be unwilling or unable to sell the entire property jointly — that heir may sell their cuota pro indiviso to a third-party investor or to a fellow heir using this contract.

Dissolving partners in a sociedad conyugal (matrimonial community property regime) — governed by Código Civil Articles 1718–1735 — acquire undivided rights to community property upon judicial or extrajudicial liquidation of the sociedad. If former spouses cannot agree on the partition of jointly-owned real estate following divorce or separation, one former spouse may sell their pro indiviso cuota to the other or to a third party using this contract, subject to the other's right of retracto under CC Article 1817.

Real estate investors who co-purchase investment properties (propiedades de inversión) as comuneros — for example, two investors jointly purchasing a commercial premises or apartment building — may need to buy out one investor's cuota through a Compraventa de Derechos Pro Indiviso when one investor wishes to exit the investment while the other wishes to retain the property.

Bank enforcement actions (ejecuciones bancarias) may result in the forced sale (remate) of a debtor's pro indiviso share in a property — the Juzgado de Letras Civil orders the auctioneer to sell the debtor's cuota at public auction, and the purchaser at auction acquires the cuota subject to all the rights of the other comuneros, including the retracto under CC Article 1817.

Farmers and agricultural landowners in regions such as the Región del Maule, Región de la Araucanía, and Región de Los Lagos who inherit agricultural land (predios agrícolas) in community with siblings or relatives regularly need to formalize the transfer of individual cuotas as part of estate resolution, using this contract in conjunction with the posesión efectiva and CBR inscription procedures.

A valid Sale of Co-Ownership Share Chile under Código Civil Articles 1812–1817 and Article 2304 must contain the following essential elements:

Party Identification (Individualización de las Partes): Full legal names, RUT issued by the Servicio de Impuestos Internos (SII), domicilio, and civil status of both the vendedor (selling co-owner) and the comprador. For inherited cuotas, the vendedor's status as heredero should be referenced, citing the posesión efectiva resolution number and the Juzgado or Registro Civil that granted it. For legal entities (sociedades, fundaciones), the razón social, RUT, and authorized representative's credentials must be stated.

Property Identification (Individualización del Bien): A precise description of the property in which the cuota pro indiviso exists — for real property: the Rol de Avalúo assigned by the Dirección de Avaluaciones of the SII, the legal description (deslindes) from the current CBR inscription, the commune (comuna) and region (región), and the cadastral surface area (superficie predial). For movable property (bienes muebles), the relevant identifying information (make, model, serial number for vehicles registered in the Registro de Vehículos Motorizados).

Cuota Description (Descripción de la Cuota): The precise fractional share being sold, expressed as a fraction (e.g., one-third, one-half) or percentage (e.g., 33.33%, 50%) of the total property. For inherited properties, the cuota is typically determined by the succession rules of Código Civil Book III and the posesión efectiva. The contract must clearly state whether the buyer is acquiring the entire cuota of the seller or only a portion of it.

Purchase Price (Precio de Compraventa): The agreed sale price in Chilean Pesos (CLP) or Unidades de Fomento (UF), and the payment terms — whether paid at signing (contado), in installments (a plazo), or partially at signing with a balance deferred. For real estate, the price must be expressed in the escritura pública and the SII will compare it against the Valor de Tasación (appraised value) for tax compliance purposes. The price serves as the reference price for any other comunero who exercises the derecho de retracto under CC Article 1817.

Right of First Refusal Notification (Notificación del Derecho de Retracto): Under Código Civil Article 1817, before or simultaneously with the Compraventa de Derechos Pro Indiviso, the vendedor must notify the other comuneros of the proposed sale — the price, terms, and identity of the buyer — giving them the opportunity to exercise the retracto and acquire the cuota under the same conditions. The notification is typically made through a Notario Público (notarial communication) or by official service through the Juzgado de Letras. Failure to notify the other comuneros does not invalidate the sale but exposes the vendedor to liability and gives the comuneros a post-sale right of retracto under CC Article 1817.

Representations and Warranties (Declaraciones y Garantías): The vendedor's representations that the cuota is free of encumbrances (gravámenes) — hypothecs (hipotecas), usufructs (usufructos), liens (embargos), prohibitions (prohibiciones de enajenar) — and free of claims by third parties; that the vendedor has legal capacity to sell; and that the cuota's dimensions and boundaries match the legal descriptions in the CBR inscription. The comprador should verify the CBR inscription status and the SII's certificado de avalúo before signing.

Registration Formalities (Formalidades de Inscripción): For real property, the escritura pública must be executed before a Notario Público and registered in the Registro de Propiedad of the CBR corresponding to the property's commune for the tradición (transfer of title) to take legal effect under Código Civil Article 686. The annotation in the Registro de Hipotecas y Gravámenes of the CBR must be checked to confirm no pre-existing encumbrances affect the cuota being sold.
