Construction on Third-Party Land Agreement Colombia (Acuerdo de Construcción en Terreno Ajeno)

A Construction on Third-Party Land Agreement Colombia (Acuerdo de Construcción en Terreno Ajeno) is a formal written contract that regulates the legal relationship between a landowner (propietario del terreno) and a builder (constructor or edificante) when the builder undertakes construction of improvements, buildings, or structures on land that belongs to another person. Under the Código Civil (CC) — Ley 57 de 1887 — Articles 738 and 739, Colombian law applies the principle of accession (accesión) whereby everything that is built on, planted in, or attached to land becomes the property of the landowner by operation of law, unless a specific agreement establishes otherwise.

The legal foundation for this arrangement derives from Book II of the Código Civil, which governs ownership and property rights. Article 738 establishes the general rule that the owner of land becomes the owner of everything that is joined to it by natural or artificial means. Article 739 addresses the specific case of construction on third-party land, establishing that when a person builds on another's land with the knowledge and without the opposition of the landowner, the landowner must choose between paying the value of the materials and labour or allowing the builder to retain ownership of the construction — a regime that the Corte Suprema de Justicia Sala de Casación Civil has interpreted extensively through decades of jurisprudence.

CC Article 1739 governs the situation where a person makes improvements (mejoras) on another's property, distinguishing between three categories of improvements with different legal consequences: mejoras necesarias (necessary improvements required to preserve the property), mejoras útiles (useful improvements that increase the property's value), and mejoras voluptuarias (luxury improvements that add comfort or aesthetic value but do not increase commercial value). Under Article 1739, the possessor in good faith (poseedor de buena fe) is entitled to compensation for both necessary and useful improvements, while the possessor in bad faith (poseedor de mala fe) is only entitled to compensation for necessary improvements.

The Constitución Política de 1991 provides the constitutional framework through Article 58, which guarantees the right to private property and established rights acquired under civil law, subject to the social and ecological function of property. Article 34 prohibits confiscation, confirming that builders who invest in construction on third-party land with authorization cannot be deprived of their investment without compensation.

Registration of construction agreements affecting real property requires compliance with the regime of the Oficina de Registro de Instrumentos Públicos under Ley 1579 de 2012 (Estatuto de Registro de Instrumentos Públicos) and Decreto 1250 de 1970. Where the agreement involves long-term construction rights, the parties may formalize the arrangement through a derecho de superficie (surface right) — though Colombia does not have a thorough statute regulating surface rights as a separate real right, the Sala de Casación Civil has recognized contractual arrangements that functionally separate land ownership from building ownership.

Municipal construction permits are governed by Ley 388 de 1997 (Ley de Ordenamiento Territorial) and Decreto 1077 de 2015 (Decreto Único Reglamentario del Sector Vivienda). The licencia de construcción must be obtained from the Curaduría Urbana or the municipal planning office (Oficina de Planeación Municipal) before beginning construction. Under Decreto 1077 de 2015 Article 2.2.6.1.2.1.1, the construction licence application must identify the legal title under which the applicant has authority to build on the property — making the written agreement between landowner and builder a prerequisite document for the licensing process.

The Superintendencia de Notariado y Registro oversees notarial formalization of agreements involving real property rights. Under Decreto 960 de 1970 (Estatuto del Notariado), agreements that create, modify, or extinguish real rights over immovable property must be formalized through escritura pública (public deed) before a Notaría and registered with the Oficina de Registro de Instrumentos Públicos to be effective against third parties.

A Construction on Third-Party Land Agreement Colombia is required whenever a person or entity intends to construct improvements, buildings, or structures on land owned by another party, and the parties wish to regulate their respective rights and obligations through a formal written contract rather than relying solely on the default rules of accession (accesión) established in the Código Civil Articles 738 and 739.

The agreement is essential when a family member, business partner, or third party constructs a residential dwelling on land owned by another person — a common arrangement in Colombian rural areas and informal urban settlements. Under CC Article 739, absent a written agreement, the landowner acquires ownership of the construction by accession and must either pay the builder the value of materials and labour or allow the builder to retain ownership — the written agreement avoids uncertainty by establishing the parties' intentions from the outset.

A Contrato de Construcción en Terreno Ajeno is needed when a commercial tenant or lessee under Ley 820 de 2003 (Ley de Arrendamiento de Vivienda Urbana) or the Código de Comercio Articles 518 through 524 (arrendamiento de local comercial) intends to make substantial improvements or structural additions to the leased premises. Under CC Article 1739, the legal treatment of improvements depends on whether the possessor acted in good faith or bad faith — a written agreement specifying the builder's authorization eliminates ambiguity regarding the builder's status.

The agreement becomes critical in commercial real estate development projects where one entity owns the land and another entity provides construction services or investment capital for building development. Under Ley 1258 de 2008 (Ley SAS) and the general corporate framework, Sociedades por Acciones Simplificadas and other legal entities entering joint development arrangements must document the allocation of construction costs, ownership rights, and profit-sharing through formal contracts registered with the Oficina de Registro de Instrumentos Públicos under Ley 1579 de 2012.

The document is required for obtaining a licencia de construcción from the Curaduría Urbana. Under Decreto 1077 de 2015 Article 2.2.6.1.2.1.1, the construction licence application must demonstrate the applicant's legal right to build on the property. Where the applicant is not the registered owner, a written authorization from the landowner — formalized as a Construction on Third-Party Land Agreement — serves as the required supporting document.

Agricultural construction arrangements under Ley 160 de 1994 (Reforma Agraria) and the regime of the Agencia Nacional de Tierras (ANT) require particular attention, as construction on parcelas adjudicadas (awarded rural plots) may be subject to restrictions on transfer and encumbrance during the restricted period established in the adjudication resolution.

A valid Construction on Third-Party Land Agreement Colombia under the Código Civil Articles 738–739 and 1739, Ley 1579 de 2012, and Decreto 1077 de 2015 must contain the following essential elements to be enforceable and to support construction licensing before the Curaduría Urbana.

Identification of Parties: Full legal name, cédula de ciudadanía number (for Colombian nationals) or cédula de extranjería (for foreign residents), and domicile of both the landowner (propietario del terreno) and the builder (constructor or edificante). Where a party is a legal entity (persona jurídica), the NIT (Número de Identificación Tributaria assigned by the DIAN), Cámara de Comercio matrícula mercantil number, and identification of the representante legal must be included, verified through a Certificado de Existencia y Representación Legal.

Property Identification: Complete identification of the land parcel (predio) where construction will take place, including the matrícula inmobiliaria number assigned by the Oficina de Registro de Instrumentos Públicos, the cédula catastral number assigned by the Instituto Geográfico Agustín Codazzi (IGAC) or the municipal catastral authority, the physical address, the lot area in square meters, and the legal boundaries (linderos) as described in the most recent escritura pública. A certificado de tradición y libertad (title and encumbrance certificate) issued within the thirty (30) calendar days preceding the agreement execution must confirm the landowner's title and reveal any liens, mortgages (hipotecas), or judicial restrictions (embargos) affecting the property.

Construction Description: Detailed specification of the construction to be undertaken, including the type of building or improvement (residential, commercial, industrial, agricultural), estimated area in square meters, number of floors, intended use, and construction timeline. Reference to the architectural plans and structural designs approved by a licensed Colombian engineer or architect under Ley 400 de 1997 (Régimen de Construcciones Sismo Resistentes) and the Norma Colombiana de Construcción Sismo Resistente NSR-10.

Authorization and Consent: Express written authorization from the landowner permitting the builder to construct on the property. Under CC Article 739, the landowner's knowledge and lack of opposition is critical — a written agreement providing explicit consent eliminates any dispute regarding whether the landowner authorized the construction. The authorization should specify whether it is exclusive or shared, revocable or irrevocable during the construction period.

Ownership of Construction: Clear designation of who owns the construction during and after completion. Under the default rule of CC Article 738, the landowner acquires ownership by accession. The parties may agree to different arrangements — including the builder retaining ownership rights over the construction for a specified period, shared ownership, or transfer mechanisms upon completion. Any arrangement derogating from the default accession rules should be formalized through escritura pública before a Notaría under Decreto 960 de 1970 and registered with the Oficina de Registro de Instrumentos Públicos.

Compensation and Payment: The financial terms governing the construction, including who bears the cost of materials and labour, any compensation payable by the landowner to the builder or vice versa, payment schedules, and the treatment of the three categories of improvements under CC Article 1739: mejoras necesarias, mejoras útiles, and mejoras voluptuarias. An independent appraisal (avalúo) by a registered appraiser listed with the Registro Abierto de Avaluadores (RAA) under Ley 1673 de 2013 may be referenced for determining fair compensation.

Construction Permits and Compliance: Allocation of responsibility for obtaining the licencia de construcción from the Curaduría Urbana under Decreto 1077 de 2015, environmental permits from the Corporación Autónoma Regional (CAR) where applicable, and compliance with the Plan de Ordenamiento Territorial (POT) of the corresponding municipality under Ley 388 de 1997.

Termination and Reversion: Conditions under which the agreement terminates, including completion of construction, expiration of the agreed term, or breach by either party. The agreement must specify what happens to the construction upon termination — whether the builder must demolish and restore the land, whether the landowner must compensate the builder for the construction, or whether the construction transfers to the landowner by accession under CC Article 738.
