Shareholders’ Agreements: Critical Clauses for Real Estate Joint Ventures

Real estate joint ventures in Mexico are frequently structured through corporations or limited liability companies that consolidate national and foreign capital for the development of projects in the Riviera Maya and the Mexican Caribbean. The legal soundness of such co-investment does not rest on corporate bylaws but on the shareholders’ agreement: a private instrument that, if well drafted, distributes control, anticipates conflicts and establishes exit mechanisms with surgical precision. If poorly drafted, it becomes the document that finances litigation.

Applicable Regulatory Framework

Shareholders’ agreements find their foundation in the General Law of Mercantile Corporations (LGSM), particularly in its articles 87 and following for corporations, being especially relevant article 91 regarding statutory content and the precepts that, by analogy and doctrinal development, support the validity of parasocial agreements among shareholders. The principle of autonomy of will enshrined in article 1832 of the Federal Civil Code (CCF) constitutes the supplementary foundation of such instruments. The reform to the LGSM published in the Federal Official Gazette on June 14, 2018 consolidated the figure of the simplified joint-stock company (SAS), although for medium and large-scale real estate joint ventures, the investment promotion corporation (SAPI), regulated in articles 2 and 13 to 21 of the Securities Market Law (LMV), offers a substantially more flexible contractual regime. Pursuant to articles 13 to 21 of the LMV, SAPIs may expressly incorporate in their bylaws restrictions on the transfer of shares, veto rights and mechanisms for the exclusion of partners that would be unenforceable in an ordinary corporation, article 13 being the provision that directly enables the corporate body to adopt such mechanisms on the terms and conditions established by the shareholders’ assembly.

Restricted Zone and Trusts: Specific Considerations for the Riviera Maya

For real estate joint ventures in Quintana Roo, the Riviera Maya and the Mexican Caribbean, there exists a restriction of constitutional scope that conditions the legal architecture of any co-investment with foreign participation: the restricted zone, defined as the strip of fifty kilometers along the coasts and one hundred kilometers along the borders of the national territory, within which foreigners cannot acquire direct ownership of real property. This prohibition, set forth in article 27 of the Constitution and developed in article 11 of the Foreign Investment Law (LIE), requires that title to coastal real estate assets be held through a trust authorized by the Secretary of Foreign Affairs, in which a Mexican credit institution acts as trustee and the foreign investor as beneficiary with rights of use, enjoyment and benefit of the property.

This trust structure has direct and material implications for the drafting of the shareholders’ agreement. When the underlying asset of the joint venture is subject to a restricted zone trust, drag along and tag along clauses do not operate solely on corporate shares: they operate on trust rights whose transfer additionally requires the consent of the trust institution and, where applicable, prior authorization from the Secretary of Foreign Affairs. The agreement must identify with precision whether the object of the transfer is the corporate share, the trust right, or both simultaneously, and must provide for the additional periods that proceedings before the aforementioned authorities inevitably generate. Omitting this interface between the corporate regime and the trust-constitutional regime is one of the most frequent structural errors in coastal real estate co-investments and can frustrate the execution of exit clauses at the moment of greatest commercial urgency. Additionally, structurers should evaluate whether the co-investment can benefit from the regime of Real Estate Investment Trusts (FIBRAs) pursuant to the LMV and applicable tax legislation, based on the profile of the project and the participating investors.

Transfer Clauses: Tag Along and Drag Along

The right of co-sale (tag along) protects minority partners: upon the sale of control by the majority shareholder, the minority shareholder has the right to sell its participation on the same economic terms negotiated with the acquiring third party. Its effectiveness depends on a precise definition of “change of control” and exercise periods, matters on which the LGSM is silent and which the agreement must cover exhaustively.

The drag-along right (drag along) operates in the opposite direction: it allows the majority shareholder to compel the minority shareholder to sell their stake to the same acquirer and on the same terms, eliminating the blocking power that a minor holder could exercise over a strategic transaction. In the context of large-scale hotel or residential projects in Quintana Roo, where institutional buyers demand one hundred percent of the capital, drag-along is not an ancillary clause but a requirement for project bankability.

The First Chamber of the Supreme Court of Justice of the Nation has held in consolidated interpretive criteria that agreements between shareholders that restrict the free transfer of shares are valid provided they do not contravene provisions of public policy or the minimum rights of partners established by law, and that such restrictions are binding between the parties that subscribed to them, although their enforceability against third parties requires registration or corporate notification. In light of the precision standards that this matter demands, it must be noted that, as of the publication date of this analysis, this criterion reflects the dominant doctrinal and jurisprudential consensus in the interpretation of the principle of freedom of contract in corporate matters, without there being a formal jurisprudential thesis integrated under a single and exclusive record referring to the inter partes enforceability of conventional restrictions on the transfer of shares.

Preemptive Rights and Valuation Mechanisms

The right of first refusal provided for in article 130 of the LGSM grants existing shareholders preference to acquire shares that a partner intends to transfer. However, article 130 admits statutory modification, and in real estate joint ventures it is standard practice to substitute or supplement that statutory right with a more sophisticated contractual mechanism that includes fixed exercise periods, procedures for authenticated notice and, critically, an independent valuation mechanism for instances in which the parties do not agree on price.

The mechanisms most commonly used in Mexican transactional practice are the shotgun clause or forced purchase-sale clause, which allows any partner to set a price at which they would indifferently buy or sell, and appraisal by an independent expert designated by the parties or, in the absence of agreement, by the judicial authority. It must be noted that the shotgun clause lacks express statutory recognition in either the LGSM or the LMV: its validity in the Mexican legal system rests entirely on the freedom of contract recognized by article 1832 of the CCF and on the willingness of the arbitral or judicial tribunal to enforce it as a lawful contractual obligation. This absence of specific normative foundation makes the robustness of the arbitration compromise clause especially critical when the agreement includes this mechanism, as an arbitral tribunal seated in Mexico with arbitrators familiar with international transactional practice offers substantially greater enforcement guarantees than those of ordinary jurisdiction. The absence of a predefined valuation mechanism converts any price dispute into prolonged litigation before the civil courts of the state.

Exit Mechanisms and Deadlock Resolution

In a joint investment between a local developer and a foreign fund, investment horizons rarely coincide. The agreement must establish with precision the maximum duration of the joint investment or the triggering event for liquidation, the conditions under which a partner may demand the sale of the underlying asset, and the remedies available in the event of a deadlock in the management bodies.

In the litigation experience of IBG Legal before the Collegiate Courts of the XXVII Circuit (Quintana Roo), controversies arising from the early dissolution of partnerships with real estate objects present a recurring pattern: the absence of contractual exit mechanisms forces partners to proceed through the judicial dissolution procedure regulated in articles 229 et seq. of the LGSM, with the costs, delays, and losses in value to the real estate asset that this inevitably entails. The contractual solution is always preferable to the judicial solution, and its absence is not a neutral omission but a decision with foreseeable and quantifiable patrimonial consequences.

For joint ventures with foreign participation, the agreement must also address the Law on Foreign Investment and its Regulations, in particular articles 7 and 8 relating to activities with special regime status, and shall contemplate whether the corporate structure requires authorization from the National Commission on Foreign Investment in the event of changes in shareholding control.

Governing Law of the Agreement and Conflicts with Mexican Corporate Law

A recurring tension in real estate joint ventures with participation of foreign funds is the foreign partner’s intention to subject the shareholders’ agreement to New York law, English law, or another jurisdiction with which it is familiar. This intention is partially viable but structurally limited. The law applicable to the agreement, as a contractual instrument between the parties, may be freely agreed upon in accordance with Mexican private international law, so that clauses of a purely obligational nature between shareholders, such as economic rights, confidentiality obligations, and dispute resolution mechanisms, may be governed by foreign law. However, the corporation or SAPI established in Mexico is subject in a mandatory and non-derogable manner to the LGSM and the LMV, as applicable. No contractual stipulation subject to foreign law may modify the rules of Mexican corporate public policy: the minimum legal quorum, the non-derogable rights of shareholders, the publicity requirements, and the dissolution procedures shall continue to be governed by Mexican law regardless of what the agreement provides. This duality of regimes must be made explicit in the governing law clause of the agreement, and transfer clauses must be drafted in such a way that their operation is simultaneously compatible with the law chosen by the parties and with the mandatory provisions of the LGSM, avoiding contradictions that could deprive exit mechanisms of their effects at the moment they are most needed.

Formalization, Enforceability Against Third Parties, and Tax Consequences

The shareholders’ agreement may be executed as a private instrument between the parties without affecting its contractual validity between them. However, its enforceability against the corporation and against third parties is a legally debated question: in order for restrictions on the transfer of shares, veto rights, and exclusion mechanisms to be enforceable against the corporation, it is advisable that the agreement be incorporated by reference in the bylaws or that it be formally notified to the management body through a public deed. In cases where the agreement modifies or complements statutory rights, or when it is intended that its effects bind future assignees of the shares, formalization before a notary public and registration in the Commercial Public Registry substantially strengthen the parties’ position in a dispute. Mexican doctrine and notarial practice are not uniform on this point, which is why the choice between a private instrument and a public deed must be a deliberate and advised decision, not an omission.

On the tax level, each exit mechanism of the agreement has a different characterization for purposes of Income Tax (ISR) and, where applicable, Real Property Acquisition Tax (ISAI). The execution of a drag along over shares whose value is derived primarily from real property located within Mexican territory may trigger specific withholdings applicable to foreign residents under Title V of the ISR Law. The execution of a shotgun clause may simultaneously generate a taxable capital gain for the seller and an acquisition subject to ISAI for the buyer, with valuations that may differ from those determined by the contractual price-fixing mechanism. Coordination with specialized tax advisors from the drafting of the agreement, and not only at the time of execution of the mechanism, is a first-order practical requirement that the agreement must anticipate through fiscal cooperation clauses between the partners.

Practical Implications

An effective shareholders’ agreement for a real estate joint venture must rigorously define the concepts of control, qualified majority, and liquidity event; establish notification procedures that generate reliable evidence for litigation purposes; include an arbitration compromise clause before the Mexico Arbitration Center (CAM) or the International Chamber of Commerce (ICC), with seat in Mexico City or Cancun depending on the project’s complexity; and provide for the applicable law and the language of the proceedings when foreign partners are involved. The choice of arbitration over ordinary jurisdiction is not merely an efficiency preference: it is a strategic decision that affects the international enforceability of the award under the New York Convention, ratified by Mexico in 1971. This consideration acquires special relevance when the agreement includes mechanisms such as the shotgun clause whose execution depends, ultimately, on the will and interpretive capacity of the court called to enforce them.

Operative Conclusion

The negotiation of the shareholders’ agreement is the moment of greatest legal leverage in the entire life of the joint venture. Tag along clauses, drag along clauses, preemptive rights, and exit mechanisms are not interchangeable standards: they are the result of technical negotiation that must anticipate the specific conflict scenarios of the project, the jurisdiction, and the profile of the partners. Incorporating them as boilerplate without adaptation to the concrete context is equivalent to not having them.
