Transfer of Partnership Interest Mexico (Cesión de Partes Sociales)

A Transfer of Partnership Interest Mexico (Cesión de Partes Sociales) is a written legal contract by which a partner (socio cedente) of a Sociedad de Responsabilidad Limitada (S. de R.L.) or Sociedad de Responsabilidad Limitada de Capital Variable (S. de R.L. de C.V.) assigns and transfers their partnership interest (parte social) to an incoming partner (socio cesionario), subject to the mandatory requirements of the Ley General de Sociedades Mercantiles (LGSM) Article 65 and the company's escritura constitutiva (articles of incorporation). The Sociedad de Responsabilidad Limitada is one of Mexico's most widely used corporate structures — particularly for small and medium enterprises (PYMES), joint ventures, and foreign-invested companies — because it combines limited liability for all partners with a more flexible and private governance structure than the Sociedad Anónima.

Under LGSM Article 65, the transfer of a parte social to a person who is not already a partner of the S. de R.L. requires the unanimous consent of all existing partners, unless the escritura constitutiva establishes a different majority threshold. This is the defining characteristic that distinguishes S. de R.L. partnership interest transfers from share transfers in a Sociedad Anónima — the consent requirement reflects the intuitu personae (personal trust) nature of S. de R.L. membership, where the identity of partners is material to all other partners. LGSM Article 65 further provides that existing partners have a right of first refusal (derecho de preferencia) to acquire the transferring partner's interest at the same price and conditions offered to the intended transferee, within the period established in the escritura constitutiva.

The legal framework governing Cesión de Partes Sociales in Mexico includes: the Ley General de Sociedades Mercantiles (LGSM, DOF 4 August 1934, reformed through June 2018) as the primary corporate statute; the Código de Comercio (CCom) Article 75 classifying the transfer as a commercial act (acto de comercio); the Código Civil Federal (CCF) for supplementary contract law principles including obligations, breach remedies, and consent requirements; and the Ley del Impuesto sobre la Renta (LISR) Articles 22 and 126 for tax treatment of the capital gain (ganancia de capital) realised by the transferring partner.

The escritura constitutiva of the S. de R.L. — the founding document registered in the Registro Público de Comercio (RPC) and executed before a Notario Público or Corredor Público — is the cornerstone document that governs all aspects of partnership interest transfers. The escritura establishes the capital aportado por cada socio (capital contribution by each partner), the value of each parte social, the transfer restrictions, the required consents, the process for valuing partes sociales upon exit, and any drag-along or tag-along rights. Any Cesión de Partes Sociales must be consistent with the escritura constitutiva — transfers that conflict with the escritura are null and void as against the company and other partners.

For Mexican S. de R.L. de C.V. structures used in joint ventures with foreign partners, the Ley de Inversión Extranjera (LIE) and its Reglamento administered by the Secretaría de Economía (SE) apply to assess whether the transfer of a parte social to a foreign person requires prior authorisation from the Comisión Nacional de Inversiones Extranjeras (CNIE), and whether the foreign partner must register with the Registro Nacional de Inversiones Extranjeras (RNIE) within 40 business days of completing the acquisition.

The Servicio de Administración Tributaria (SAT) requires that all partners' RFC numbers be documented in the Cesión de Partes Sociales. The outgoing partner must calculate and declare any gain on the transfer under LISR Article 126 (for individuals) or Article 9 (for corporations), using the costo fiscal calculation method under LISR Article 22, which adjusts the original capital contribution for inflation using the INPC (Índice Nacional de Precios al Consumidor).

A Transfer of Partnership Interest Mexico is required whenever a partner of a Sociedad de Responsabilidad Limitada (S. de R.L.) or S. de R.L. de C.V. wishes to sell, donate, or otherwise assign their parte social to another person — whether an existing partner or an incoming third party. The Cesión de Partes Sociales is the legal instrument that effects the transfer and documents compliance with the mandatory consent and preferential acquisition procedures under LGSM Article 65.

The agreement is needed in business succession planning when a founding partner of an S. de R.L. de C.V. retires, dies, or wishes to pass their interest to a family member or management buy-in team. Mexican family businesses structured as S. de R.L. de C.V. frequently use Cesión de Partes Sociales together with Convenios de Socios (partners' agreements) to govern generational transfers while preserving family control.

A Cesión de Partes Sociales is required when a private equity fund (fondo de capital privado) or venture capital investor acquires an interest in a Mexican PYME structured as an S. de R.L. de C.V. The incoming investor's capital contribution, governance rights, and exit mechanism are documented through a combination of the transfer agreement and an amended escritura constitutiva or a separate partners' agreement.

The agreement is needed when one partner in an S. de R.L. joint venture exercises their right to buy out the other partner's interest — whether under a put or call option established in the original joint venture agreement or following a dispute resolution process. The Cesión de Partes Sociales documents the agreed exit price and the formal handover of the parte social.

When a foreign company that holds a parte social in a Mexican S. de R.L. de C.V. is acquired by or merges with another foreign entity, the change in indirect control over the Mexican partner's parte social may constitute a deemed transfer requiring a Cesión de Partes Sociales and notification to the CNIE and RNIE under the Ley de Inversión Extranjera (LIE).

Under LGSM art. 65 and Código de Comercio art. 75, the Cesión de Partes Sociales must be documented in writing and inscribed in the Libro de Socios (Partners' Register) maintained by the company and in the Registro Público de Comercio (RPC) through a notarial deed (escritura notarial) or public instrument — without these formalities, the transfer is not effective as against third parties.

A valid Transfer of Partnership Interest Mexico under the Ley General de Sociedades Mercantiles (LGSM) Article 65 must contain the following essential elements to be effective against the company, the other partners, and third parties:

Identification of Parties: Full legal names, RFC (Registro Federal de Contribuyentes), and domicilios of the transferring partner (socio cedente) and the incoming partner (socio cesionario). For corporate partners, the Registro Público de Comercio folio number and the name and authority of the legal representative (representante legal) must be documented with a certified copy of the relevant poder notarial.

Company Identification: Full name (razón social), RFC, Registro Público de Comercio folio, and domicilio social of the S. de R.L. or S. de R.L. de C.V. whose parte social is being transferred. Reference to the escritura constitutiva date, notario público or corredor público who executed it, and the relevant RPC inscription data.

Description of the Parte Social: The total capital of the S. de R.L., the cedente's current capital participation (participación en el capital social), the percentage or amount of the parte social being transferred, and the book value (valor contable) per the most recent balance sheet (balance general) approved by the partners' meeting (asamblea de socios). For S. de R.L. de C.V. structures, the distinction between fixed capital (capital fijo) and variable capital (capital variable) must be addressed.

Unanimous or Majority Consent of Partners: Documented consent of all existing partners (or the majority established in the escritura constitutiva) to the transfer, as required by LGSM Article 65 — typically evidenced by minutes of a partners' meeting (acta de asamblea de socios) signed by all consenting partners. Without this consent, the transfer is void as against the company and non-consenting partners.

Right of First Refusal (Derecho de Preferencia): Statement documenting that the preferential acquisition right of existing partners under LGSM Article 65 and the escritura constitutiva has been complied with — including the date and form of the offer, the offering period, and the documented waiver or non-exercise by all entitled partners within the prescribed timeframe.

Transfer Price and Valuation: The agreed transfer price (precio de cesión) in MXN, the valuation method used (e.g., book value per most recent audited balance sheet, discounted cash flow, or EBITDA multiple), and the payment terms. For related-party transfers, compliance with LISR transfer pricing rules under Articles 179–184 and SAT documentation requirements.

RPC Inscription and Notarial Formality: Transfer of partes sociales in an S. de R.L. requires inscription in the Registro Público de Comercio (RPC) through a notarial deed (escritura notarial ante Notario Público) or instrument executed before a Corredor Público — unlike share transfers in an S.A., which may be effected by endorsement. An amendment to the escritura constitutiva (or a supplementary public instrument) is required to reflect the new partner and updated capital ownership.

Updated Libro de Socios: Undertaking to update the Libro de Socios (Partners' Register) maintained by the company under LGSM Article 73, reflecting the transferee as the new holder of the transferred parte social.

Tax Representations: Acknowledgment by the cedente of their obligation to calculate and declare capital gains (ganancias de capital) under LISR Articles 22 and 126, and the cesionario's acknowledgment of their new tax basis (costo fiscal) in the acquired parte social.
