Silent Partnership Agreement Mexico (Convenio de Asociación en Participación)

A Silent Partnership Agreement Mexico (Convenio de Asociación en Participación or AP) is a commercial contract governed exclusively by the Código de Comercio (CCom) Articles 252 through 259, by which a merchant (comerciante) — called the asociante — agrees to share the profits or losses of one or more commercial transactions with one or more persons who contribute capital, goods, or services — called asociados (silent partners). Unlike a general commercial partnership (sociedad colectiva) or a limited partnership (sociedad en comandita) under the Ley General de Sociedades Mercantiles (LGSM), the asociación en participación does not create a separate legal entity (no tiene personalidad jurídica propia) — it exists solely as a contractual relationship between the asociante and the asociados, and it does not appear in the Registro Público de Comercio. The asociante conducts all business in their own name and remains solely and exclusively liable to third parties — third parties (terceros) have no legal relationship with the asociados, who remain invisible (invisibles) in the commercial relationship.

The asociación en participación (AP) is one of Mexico's most distinctive and frequently used commercial structures, explicitly codified in CCom Articles 252–259 since the original Código de Comercio of 1889. The AP allows an investor (the asociado) to participate in the profits of a business run by an experienced operator (the asociante) without taking on direct operational responsibilities or becoming visible to the market. CCom Article 252 defines the AP as the contract by which one merchant grants a share in the profits (participación en las utilidades) of their commercial operations to other persons who contribute capital, services, or goods, in exchange for bearing a proportional share of the losses. The AP is classified as a commercial act under CCom Article 75 — the same article that governs all commercial acts in Mexico.

The tax treatment of the asociación en participación in Mexico was fundamentally reformed by the Ley del Impuesto sobre la Renta (LISR). Under current LISR Article 7, an asociación en participación is treated as a transparent entity for corporate tax purposes when the asociante is a legal entity (persona moral) — the asociante reports all income and deductions on its own ISR return, and no separate tax return is filed by the AP itself. When the asociante is an individual (persona física), different income classification rules apply under LISR Title IV. The Código Fiscal de la Federación (CFF) Article 17-B establishes special rules for the AP's tax registration — when the AP generates income subject to tax, it must obtain its own RFC from the SAT, separate from the asociante's individual RFC, making it a fiscal entity (entidad fiscal) even though it lacks legal personality.

The Suprema Corte de Justicia de la Nación (SCJN) has developed extensive jurisprudencia on the AP — key holdings include: the AP's invisibility to third parties is absolute under CCom Article 254 (third parties cannot claim against the asociado even if they discover the AP's existence); the asociado's liability is limited to the capital contributed and does not extend to the asociante's general commercial obligations; and the AP agreement is not subject to registration in the RPC, preserving the confidentiality of the investment relationship.

The AP is widely used in real estate development (desarrollo inmobiliario) in Mexico — a developer (promotor) acts as asociante, a capital investor acts as asociado contributing purchase or construction funds, and the parties share the eventual sale proceeds proportionally. The AP is also used in restaurant and hospitality ventures, retail franchising expansion, agricultural production financing, and mining projects — any sector where an operator with expertise needs capital from an investor who prefers to remain invisible and limit liability to the invested amount.

A Silent Partnership Agreement Mexico is needed when an investor (asociado) wishes to participate in the profits of a specific business operation or commercial project managed by an experienced operator (asociante), without creating a new legal entity, without incurring personal liability beyond the contributed capital, and without becoming publicly identifiable as a business partner.

The Convenio de Asociación en Participación is required in real estate development projects where a capital investor — an individual, family office, or investment fund — provides the acquisition price (precio de adquisición) or construction financing (financiamiento de construcción) for a property development, and the developer contributes land rights (derechos sobre el terreno), construction management (gestión de construcción), and commercial relationships with buyers. The AP allows the investor to participate in the profit margin of the development without acquiring any property rights directly or appearing as a co-owner in the Registro Público de la Propiedad.

The AP is needed when a foreign investor wishes to participate in a Mexican business operation without incorporating a new subsidiary or creating a visible presence in Mexico — the AP allows participation in profits while the associated entity handles all operational, regulatory, and commercial activities under Mexican law. Foreign AP investors must comply with RNIE registration under the LIE and applicable income tax withholding under LISR Article 164.

A Convenio de Asociación en Participación is needed when a business owner (asociante) needs working capital (capital de trabajo) or project-specific financing from a private investor who prefers a profit-sharing structure over a fixed interest return — the AP provides the investor with upside participation while the business owner retains full operational control and public commercial identity.

The AP is required in agricultural financing (financiamiento agrícola) — a capital investor (asociado) contributes funds for seasonal crop production, and the producer (asociante) contributes land, equipment, and agricultural expertise. The parties share the harvest proceeds under the AP agreement without creating a new agricultural entity.

Under CCom arts. 252–259 and LISR art. 7, Mexican businesses and investors should use a formal written Convenio de Asociación en Participación — CCom Article 252 does not require writing for the AP's validity, but written documentation is essential to define contribution amounts, profit shares, loss limits, and the asociante's obligations to account for results, and is critical evidence in any tax audit or commercial dispute.

A valid Convenio de Asociación en Participación Mexico under Código de Comercio Articles 252–259 must contain the following essential elements to be effective, tax-compliant, and enforceable:

Identification of Asociante and Asociados: Full legal name, RFC, Registro Público de Comercio reference (for legal entities), domicilio, and authorised representative of the asociante (the visible merchant who conducts business). For each asociado, full name or razón social, RFC, domicilio, and — if a legal entity — the poder notarial reference authorising the signing representative. The CCom Article 252 does not limit the number of asociados — multiple investors may participate in a single AP agreement with the same asociante.

Description of the Commercial Operation: A precise description of the specific commercial transaction or ongoing business activity (negocio o transacción específica) that is the subject of the AP. This may be a single transaction (e.g., a specific real estate development on a defined property), a series of transactions (e.g., a season's agricultural production), or an ongoing business (e.g., a restaurant operation for a defined term). CCom Article 252 requires that the AP relate to commercial transactions — purely civil or non-commercial activities are not appropriate subjects for an AP.

Contribution of the Asociado: A precise description and valuation of each asociado's contribution (aportación) — cash (capital en efectivo) expressed in MXN, goods (bienes) with their appraised value (valor de avalúo), or services (servicios) with their agreed monetary equivalent. CCom Article 253 requires that the asociado's contribution be clearly defined — vague contribution descriptions create disputes about the contribution obligation and complicate the tax treatment under LISR and the SAT's auditing of AP transactions.

Profit and Loss Sharing Percentage: The agreed percentage of profits (porcentaje de participación en utilidades) allocated to each asociado and to the asociante. Under CCom Article 253, the parties are free to agree any profit percentage, including asymmetric shares that do not correspond to contribution percentages. However, the Código Civil Federal Article 2697 (incorporated by reference through CCom general contract principles) prohibits leonine pacts — an AP clause that assigns all profits to one party or all losses to the other party is void. The CCom Article 255 provides that the asociado's maximum loss exposure is limited to the value of the contributed capital — the asociado cannot be made to suffer losses beyond the contribution.

Limitation of Asociado's Liability: An express clause confirming that under CCom Article 254, the asociado has no commercial relationship with third parties dealing with the asociante — the asociado is not liable to the asociante's creditors beyond the amount contributed. The invisibility of the asociado to third parties is a fundamental characteristic of the AP under Mexican law and must be preserved — any public disclosure of the AP's existence or the asociado's identity may be used to challenge the AP structure.

Accountability and Reporting: The asociante's obligation to maintain separate accounts (cuentas separadas) for the AP transactions and to render periodic accounts (rendición de cuentas) to the asociados — typically quarterly or annually — including a detailed income and expense statement and a calculation of the distributable profit or loss for the period. CCom Article 256 obliges the asociante to render accounts on the terms agreed or at the end of each business year. The AP agreement should specify the accounting standards (NIF) applicable and whether the accounts must be audited by an independent Contador Público Certificado (CPC).

Term and Termination: The duration of the AP (plazo de vigencia) — either a fixed term, tied to the completion of a specific project, or indefinite subject to notice of termination. CCom Article 257 provides that the AP terminates by: expiration of the agreed term; completion of the specific transaction; loss of all contributed capital; death or insolvency of the asociante (unless otherwise agreed); or mutual agreement. The AP agreement should specify the process for winding up (liquidación) — returning contributed capital, distributing accumulated profits, and settling outstanding obligations.

SAT and LISR Compliance: A clause confirming the AP's tax treatment under LISR Article 7 — whether the AP will obtain a separate RFC from the SAT, who will file the AP's tax declarations (if required), how ISR withholding on profit distributions to the asociado will be managed, and whether the AP qualifies for any special tax regime (régimen fiscal especial) under the Resolución Miscelánea Fiscal (RMF) published annually by the SAT.
