Share Transfer Agreement Mexico (Contrato de Cesión de Acciones)

A Share Transfer Agreement Mexico (Contrato de Cesión de Acciones) is a written legal contract by which a shareholder (accionista cedente) of a Sociedad Anónima (S.A.) or Sociedad Anónima de Capital Variable (S.A. de C.V.) transfers ownership of one or more shares (acciones) to a buyer (accionista cesionario), subject to the requirements established in the Ley General de Sociedades Mercantiles (LGSM) Articles 111 through 124. The LGSM, published in the Diario Oficial de la Federación on 4 August 1934 and continuously reformed — including major corporate governance reforms published 14 June 2018 — is the primary statute governing share transfers in Mexican commercial corporations.

Under LGSM Article 111, shares of a Sociedad Anónima represent equal fractions of the corporate capital (capital social) and confer upon their holder the rights and obligations established in the articles of incorporation (acta constitutiva) and the LGSM. LGSM Article 120 establishes that the transfer of shares is effected by endorsement (endoso) on the share certificate (título accionario) itself and by inscription in the Share Registry Book (Libro de Registro de Acciones) maintained by the company, which constitutes the definitive record of share ownership for all legal purposes. Article 128 LGSM requires companies to maintain the Share Registry Book, and Article 129 provides that only those shareholders registered therein may be recognised by the company.

The legal framework for share transfers in Mexican S.A. and S.A. de C.V. corporations involves multiple layers of regulation. The Código de Comercio (CCom) Article 75 classifies share transfers as commercial acts (actos de comercio), subjecting them to commercial law principles. The Código Civil Federal (CCF) applies subsidiarily for general contractual obligations. For regulated industries, additional approvals from sector regulators — such as the Comisión Nacional Bancaria y de Valores (CNBV) for financial entities, the Comisión Federal de Telecomunicaciones (CFT) for telecom companies, or the Secretaría de Economía (SE) for foreign investment under the Ley de Inversión Extranjera (LIE) — may be required.

Restrictions on share transferability are a critical feature of Mexican S.A. structures. The acta constitutiva and estatutos sociales (corporate bylaws) frequently include a derecho de tanto (right of first refusal) under LGSM Article 130 — before transferring shares to a third party, the selling shareholder must offer them first to existing shareholders at the same price and terms. Failure to comply with the derecho de tanto renders the transfer voidable at the election of the non-notified shareholders. The Contrato de Cesión de Acciones must document compliance with or waiver of this right.

For Sociedades Anónimas Bursátiles (SABs) — publicly listed companies — share transfers on the Bolsa Mexicana de Valores (BMV) are governed by the Ley del Mercado de Valores (LMV) and supervised by the CNBV. For non-listed companies (Sociedades Anónimas Cerradas), the transfer process is private but must comply with the corporate bylaws and LGSM formalities. The Registro Público de Comercio (RPC) records corporate modifications, and significant share transfers that alter control of the company may require an extraordinary shareholders' meeting (asamblea extraordinaria de accionistas) under LGSM Article 182 to amend the corporate minutes.

The Contrato de Cesión de Acciones in Mexico also interacts with tax law. The Servicio de Administración Tributaria (SAT) treats the gain on share transfers as capital gains (ganancias de capital) subject to the Ley del Impuesto sobre la Renta (LISR) — for individuals, Article 126 LISR applies; for corporations, the general corporate income tax rate under Article 9 LISR applies. The RFC (Registro Federal de Contribuyentes) of both transferor and transferee must be documented in the agreement for SAT compliance purposes, and the tax base (costo fiscal) of shares must be calculated according to LISR Article 22.

A Share Transfer Agreement Mexico is required whenever a shareholder of a Sociedad Anónima (S.A.) or Sociedad Anónima de Capital Variable (S.A. de C.V.) sells, donates, or otherwise transfers their shares to another person — whether an existing shareholder or a new investor. The Contrato de Cesión de Acciones documents the transaction and creates the legal record necessary for inscription in the Share Registry Book under LGSM Article 128.

The agreement is required in business succession planning — when a founder or majority shareholder transfers shares to family members, management, or strategic investors. Mexican family businesses frequently use share transfers to transition ownership between generations while maintaining operational control through shareholders' agreements (Convenios de Accionistas) that restrict the transferee's voting rights.

A Contrato de Cesión de Acciones is needed in venture capital and private equity transactions in Mexico — when a startup incorporated as an S.A. de C.V. accepts investment from a fondo de capital privado (FCP) registered with the CNBV, the share transfer or subscription agreement formalises the investor's entry into the company's capital structure and their rights under the Ley del Mercado de Valores (LMV) and the Ley de Fondos de Inversión.

The agreement is required whenever the derecho de tanto (right of first refusal) under LGSM Article 130 has been exercised or formally waived — without written documentation, the transfer may be challenged by existing shareholders who claim their preferential acquisition right was not respected.

Share transfers resulting from mergers (fusiones), spin-offs (escisiones), or acquisitions (adquisiciones) of Mexican companies require a share transfer agreement as part of the broader transaction documentation under LGSM Articles 222–228. The Contrato de Cesión de Acciones forms part of the closing documents (documentos de cierre) in M&A transactions.

When a shareholder exits a company due to death, disability, bankruptcy, or exclusion under the corporate bylaws, the share transfer agreement documents the compulsory transfer of shares to remaining shareholders or to the company itself for cancellation (amortización) under LGSM Article 138, calculating the exit value (valor de salida) based on the last approved balance sheet.

A valid Share Transfer Agreement Mexico under the Ley General de Sociedades Mercantiles (LGSM) Articles 111–124 must contain the following essential elements to be legally effective and recordable in the Share Registry Book:

Identification of Transferor and Transferee: Full legal name, RFC (Registro Federal de Contribuyentes), CURP if applicable (for individuals), domicilio fiscal, and identity document reference for both the seller (accionista cedente) and buyer (accionista cesionario). For corporate shareholders, the Registro Público de Comercio folio number, RFC, and name of the legal representative (representante legal) with certified power of attorney (poder notarial) must be included.

Corporate Information: Full legal name of the company (razón social), RFC of the company, Registro Público de Comercio inscription data (folio mercantil), domicilio social, and the authorised capital (capital social autorizado) and paid-up capital (capital social pagado) of the S.A. or S.A. de C.V. whose shares are being transferred.

Description of Shares Being Transferred: Number of shares transferred (número de acciones cedidas), series and class of shares (e.g., Serie A, acciones ordinarias nominativas), face value per share (valor nominal), and the share certificate numbers (números de títulos accionarios) representing the transferred shares. Confirmation that the shares are fully paid-up (acciones totalmente liberadas) under LGSM Article 117 and free from liens (libres de gravámenes), pledges (prendas), or third-party rights.

Transfer Price and Payment Terms: The agreed transfer price (precio de cesión) in Mexican pesos (MXN), payment method (e.g., wire transfer to CLABE account), and payment schedule. For tax compliance with the Servicio de Administración Tributaria (SAT), the price must reflect fair market value (valor de mercado) or justify any departure therefrom — LISR Article 22 requires the transferor to calculate and report capital gains (ganancias de capital) based on the costo fiscal of shares.

Compliance with Right of First Refusal: Express statement that the derecho de tanto established in LGSM Article 130 and/or the corporate bylaws (estatutos sociales) has been complied with — including the date the offer was made to existing shareholders, the offer period, and either the acceptance or documented waiver by all shareholders entitled to exercise the right.

Share Registry Inscription: Undertaking by the company (represented by its secretary or delegate) to inscribe the transfer in the Libro de Registro de Acciones under LGSM Article 128 within a specified period (typically 5 business days from signing), and to issue new share certificates (títulos accionarios) to the transferee reflecting the acquisition.

Shareholders' Meeting Approval: Where the corporate bylaws require shareholder approval for share transfers — common in S.A. de C.V. structures — the minutes of the relevant ordinary or extraordinary shareholders' meeting (asamblea de accionistas) approving the transfer must be attached as an exhibit.

Representations and Warranties: Seller's representations that the shares are legally owned (propiedad legítima), fully paid-up (totalmente liberadas), free from encumbrances (libres de gravámenes), that no litigation (litigios) or claims (reclamaciones) are pending against the shares, and that all pre-emptive and preferential rights have been properly addressed.

Governing Law and Jurisdiction: Submission to the laws of Mexico and the jurisdiction of the federal courts (Juzgados de Distrito en Materia Mercantil Federal) or the agreed commercial arbitration body — many M&A transactions in Mexico include arbitration clauses under the Centro de Arbitraje de México (CAM) rules or ICC rules.
