Real Property Loan for Use (Comodato) Mexico

A Real Property Loan for Use (Comodato de Inmueble) Mexico is a gratuitous contract under which the comodante (lender) delivers a specific immovable property to the comodatario (borrower) for temporary use, with the obligation to return the same property in the same condition at the end of the agreed term, governed by the Código Civil Federal (CCF) published in the Diario Oficial de la Federación on 26 May 1928 and in continuous force since 1932, specifically Articles 2497 through 2515. Unlike arrendamiento (lease), the comodato is esencialmente gratuito — essential gratuity is a defining characteristic under Article 2497 CCF, meaning the comodatario pays no rent or compensation for the use of the property.

The comodato de inmueble is one of the classical real property contracts in Mexican civil law, widely used between family members (préstamo familiar), within corporate groups (between parent and subsidiary companies), in religious institutions, and in social-purpose arrangements where a property owner allows another party to use land or buildings without charging rent. Article 2498 CCF requires that the comodante be the owner of the property or have legal authority to grant use rights — a bare licensee or tenant cannot validly create a comodato over property they do not own or control.

The Código Civil Federal establishes in Article 2501 that the comodatario is obligated to care for the property with the diligence of a buen padre de familia (prudent person), bear the ordinary expenses of use (gastos ordinarios de conservación), and return the property at the end of the term in the same state, subject only to normal wear arising from authorized use. The comodatario is not permitted to use the property for purposes other than those agreed in the contract, nor to sub-lend the property to third parties without the comodante's express written consent under Article 2505 CCF.

Ownership of the property (dominio) remains exclusively with the comodante throughout the duration of the comodato — Article 2497 CCF confirms this expressly. The comodatario acquires only the right of use (derecho de uso) and possession for the agreed purposes, without any right of retention (derecho de retención) except in very limited circumstances recognized by Article 2509 CCF for extraordinary expenses. The separation between use and ownership makes the comodato a fundamentally different instrument from a lease (arrendamiento under Articles 2398 onward) or a usufruct (usufructo under Articles 980 onward).

Mexican courts — including the Suprema Corte de Justicia de la Nación and the Tribunales Colegiados de Circuito — have produced extensive jurisprudencia on the comodato de inmueble, addressing issues such as the precarious nature of the comodatario's possession (posesión precaria), the right of the comodante to recover the property through the acción de comodato, the distinction between ordinary and extraordinary expenses, and the liability of the comodatario for total loss or deterioration of the property beyond normal wear. The precarious nature of the comodatario's possession means courts do not recognize adverse possession (prescripción adquisitiva) claims by comodatarios — a critically important protection for comodantes.

For income tax purposes under the Ley del Impuesto Sobre la Renta (LISR), a comodato de inmueble where the comodante is a persona moral (company) lending property to a related party may trigger a deemed income analysis under Article 179 LISR transfer pricing rules, with the SAT potentially attributing a fair market rental value to the transaction. Individual comodantes between family members generally do not face income tax consequences, but should document the genuinely gratuitous nature of the arrangement.

A Real Property Loan for Use (Comodato de Inmueble) Mexico is required or strongly advisable whenever a property owner in Mexico intends to allow another person or entity to use their real property without charging rent, for a defined purpose and term, while retaining full ownership and the right to recover the property.

Family comodatos are the most common use case in Mexico — parents allowing adult children to occupy a home, siblings sharing use of inherited property, or grandparents lending a rancho or commercial premises to family-owned businesses. Without a written comodato contract, family occupants can accumulate possessory rights (derechos posesorios) that, while not sufficient for adverse possession against a documented comodante, create practical difficulties in eviction proceedings and generate disputes over improvements (mejoras) and expenses.

Corporate group comodatos are essential when a parent company (empresa controladora) owns real property and allows a subsidiary (empresa subsidiaria) or affiliated entity to use a warehouse, factory, or office building at zero rent. Under Article 179 LISR and SAT transfer pricing guidelines, the absence of a written comodato contract risks reclassification of the arrangement as a taxable benefit or a disguised lease, triggering ISR and IVA consequences for both parties.

Religious and non-profit organizations frequently use comodato contracts when a private individual or foundation lends a building to a church, school, or civil association (asociación civil under Articles 2670–2687 CCF) for social purposes. The Instituto Nacional para la Educación de los Adultos (INEA), municipal governments, and ejido communities (governed by the Ley Agraria) also use comodato structures for public-purpose property use without formal alienation of title.

A comodato is also needed when a developer allows a prospective buyer to occupy a property during a purchase option period — this arrangement must be carefully structured as a comodato (not a lease) to preserve the seller's ownership rights and avoid creating tenant protections under the arrendamiento provisions of the CCF.

Under Article 2497 CCF and Articles 2501–2515 CCF, the written contract must specify the property (inmueble determinado), authorized use (uso autorizado), term (plazo), and return obligations (obligaciones de devolución) to be fully enforceable. Oral comodatos are valid under Mexican civil law but extremely difficult to prove and enforce in court.

A valid Contrato de Comodato de Inmueble Mexico under Articles 2497–2515 of the Código Civil Federal must contain the following essential elements to be fully enforceable and to protect both the comodante and the comodatario:

Identification of Parties: Full legal names, RFCs, and addresses of both the comodante (property owner/lender) and the comodatario (borrower). If either party is a persona moral (company), include corporate name, RFC, constitutive act data, and the name and authority of the legal representative (representante legal) who signs. Article 2498 CCF requires the comodante to have legal authority to grant use rights.

Description of the Property (Inmueble): A precise legal description of the real property being loaned, including: address and municipality; cadastral reference (clave catastral); Registro Público de la Propiedad folio number (folio real) if available; surface area (superficie); and any improvements (construcciones) included in the comodato. The comodato must be for a specific, identifiable property — general descriptions are insufficient under Article 2497 CCF.

Authorized Use (Uso Autorizado): The specific purpose for which the comodatario may use the property — for example, residential occupation, commercial operation, agricultural use, or social-purpose activity. Article 2505 CCF establishes that use beyond the authorized purpose gives the comodante the right to immediate termination and recovery of the property.

Term (Plazo): The agreed duration of the comodato — either a fixed term (plazo determinado) or a term that continues until the purpose is fulfilled (plazo indeterminado until the agreed use concludes). Under Article 2508 CCF, the comodante may demand return of the property before the agreed term if they face an urgent and unforeseen need (necesidad urgente e imprevista) for the property — this is a mandatory right that cannot be contractually waived.

Return Obligations (Obligaciones de Devolución): The comodatario's obligation to return the property in the same condition received, subject only to natural wear from authorized use (deterioro normal), under Article 2501 CCF. The contract should specify the condition of the property at delivery (estado del inmueble al momento de la entrega) through an inventory or inspection report (acta de entrega-recepción) attached as an exhibit.

Ordinary Expenses (Gastos Ordinarios): Under Article 2503 CCF, the comodatario bears all ordinary expenses of conservation and use (gastos ordinarios de conservación y uso) — utilities, routine maintenance, minor repairs. These expenses are not reimbursable from the comodante.

Extraordinary Expenses (Gastos Extraordinarios): Extraordinary conservation expenses (gastos extraordinarios de conservación) that are urgent and necessary to preserve the property may be reimbursed by the comodante under Article 2507 CCF, provided the comodatario notified the comodante before making them and the comodante refused or was unable to make them. The contract should define what qualifies as extraordinary and the notification procedure.

Liability for Loss or Damage (Responsabilidad por Pérdida o Deterioro): The comodatario is liable for total loss (pérdida total) or deterioration (deterioro) of the property caused by their fault or negligence, by unauthorized use, or by failure to take reasonable protective measures under Articles 2501–2502 CCF. The contract should specify insurance obligations (obligaciones de seguro) and who maintains the property insurance policy.

Prohibition on Sub-Lending (Prohibición de Subcomodato): Express prohibition on the comodatario lending, subletting, or otherwise granting use of the property to third parties without prior written consent of the comodante, per Article 2505 CCF.

Applicable Law and Jurisdiction: The contract should state that it is governed by the Código Civil Federal and designate the Juzgado Civil competente in the relevant jurisdiction (fuero local or federal) for any disputes.
