Cross-Border Advisory
Legal counsel for US and international companies establishing or expanding operations in Mexico. Corporate structuring, labor compliance, regulatory requirements and cross-border legal strategy.
Schedule a Consultation Corporate Law in MexicoMexico offers compelling business opportunities for foreign companies: geographic proximity to the United States, an extensive free trade agreement network including the USMCA, a large manufacturing sector, a growing domestic market and significant real estate development activity, particularly in the border region.
At the same time, operating in Mexico involves navigating a legal environment that differs substantially from the US and other jurisdictions. Mexican corporate law, labor law, regulatory compliance requirements and contractual practice have their own logic — and assumptions imported from other jurisdictions frequently generate legal exposure.
Treu Legal & Business advises foreign companies — primarily US-based — on the legal requirements and strategic considerations for establishing and operating in Mexico, with particular expertise in the Baja California corridor given our location in Ensenada and the cross-border dynamics of this region.

The following framework reflects the primary legal considerations for a foreign company establishing operations in Mexico. The specific requirements vary depending on the company's sector, structure and operational model.
Foreign companies can operate in Mexico through a locally incorporated subsidiary (the most common approach), a branch office (sucursal), or representative office. Each option has distinct corporate, tax and operational implications. A subsidiary under Mexican law provides liability separation and is generally preferred for ongoing commercial operations.
Incorporation requires formalization before a Mexican notary public, registration with the Public Registry of Commerce (Registro Público de Comercio), and registration with the tax authority (SAT) for RFC purposes. Foreign shareholders may be subject to specific foreign investment registration requirements depending on the industry and ownership percentage.
Hiring employees in Mexico creates significant legal obligations from the first day of employment. Employment contracts must be executed in Spanish, comply with the LFT's minimum standards, and include legally required benefits. IMSS registration must be completed before the employee starts work. A properly structured labor framework is essential from the outset.
Depending on the industry, foreign companies may face sector-specific permits and authorizations, anti-money laundering obligations under the LFPIORPI, data privacy compliance requirements, and industry-specific regulatory frameworks. Early compliance assessment prevents costly retroactive remediation.
Commercial contracts in Mexico should be governed by Mexican law and drafted in Spanish for operational purposes. Contracts drafted exclusively in English or governed by foreign law create enforceability challenges in the Mexican legal system. Supply agreements, distribution contracts and service agreements all require careful drafting adapted to the Mexican legal context.
Analysis of available legal structures for foreign investment in Mexico, comparative assessment of options, and implementation of the selected structure including incorporation, shareholder documentation and governance design.
Design of the employment framework for the Mexican operations, including contract templates, required benefits structuring, IMSS registration, internal policies and compliance protocols under the LFT.
Drafting and review of commercial agreements governing operations in Mexico, including supply contracts, distribution agreements, service contracts and joint venture documentation adapted to Mexican legal requirements.
Assessment of sector-specific regulatory requirements, anti-money laundering obligations, data privacy compliance and other regulatory frameworks applicable to the company's operations in Mexico.
Continuous legal advisory for foreign companies operating in Mexico, functioning as an external legal department for day-to-day corporate, commercial and labor legal matters.
Legal advisory that integrates the Mexican legal perspective with the cross-border operational reality of companies working between Mexico and the United States — contracts, structures and decisions that need to function on both sides of the border.
Operating in Mexico without a locally incorporated entity is legally possible in limited circumstances — for example, occasional cross-border transactions. However, regular commercial activity, hiring employees in Mexico, executing contracts with Mexican parties, or maintaining a physical presence will generally trigger the requirement to establish a formal Mexican legal presence. Operating without the appropriate structure creates significant tax and legal liability exposure.
A subsidiary (filial) is a separately incorporated Mexican entity — typically an S.A. de C.V. or S. de R.L. de C.V. — with its own legal personality, distinct from the foreign parent. A branch office (sucursal) is an extension of the foreign entity itself, without separate legal personality. Subsidiaries are generally preferred because they provide liability separation between the Mexican operations and the foreign parent, and are operationally simpler to manage under Mexican law.
The USMCA (T-MEC in Mexico) provides significant tariff and market access benefits for companies operating across the US-Mexico border, but it does not substitute for compliance with Mexican domestic law. A properly structured Mexican operation is required to take full advantage of USMCA benefits, particularly in manufacturing and goods trade. The USMCA's labor chapter also imposed significant obligations on Mexico that have been implemented through domestic labor reforms — changes that directly affect employment practices for all companies operating in Mexico, including foreign-owned ones.
Foreign companies hiring employees in Mexico must comply fully with the Federal Labor Law regardless of the nationality of the employer. This includes executing written employment contracts in Spanish, registering employees with the IMSS before their first day of work, providing legally mandated benefits (Christmas bonus, vacation, vacation premium, profit sharing), complying with the applicable collective bargaining framework where applicable, and maintaining proper employment documentation. The employer of record must be the Mexican entity — not the foreign parent company.
