About Due Diligence Law in Mexico, Mexico

Due diligence in Mexico involves a structured review of a target business, asset, or project before completing a transaction. The process checks legal, financial, regulatory, and operational aspects to identify risks and liabilities. In Mexican practice, due diligence is essential in mergers and acquisitions, real estate deals, and foreign investment transactions to support informed decision making.

Practitioners often tailor due diligence to the deal type, such as corporate due diligence for acquisitions, tax due diligence for transfer pricing and compliance, or IP due diligence for technology or brand assets. Key areas typically reviewed include corporate structure, shareholder rights, contracts, labor obligations, tax compliance, licenses, permits, and environmental liabilities. For data handling, privacy compliance under Mexican law also informs the due diligence scope.

To ensure accuracy and enforceability, rely on official texts and guidance from Mexican authorities and professional bodies. The official text of core laws, and related regulatory guidance, is published by government portals such as DOF and gob.mx.

Why You May Need a Lawyer

Mexico-specific due diligence requires navigation of local corporate, tax, labor, and data protection laws. A focused lawyer helps prevent post-closing disputes and regulatory penalties. Below are concrete scenarios where specialized counsel is essential.

• Mergers and acquisitions involving a Mexican subsidiary - A foreign buyer seeks to acquire a Mexican company and must verify corporate capacity, share transfer rules, and potential liabilities hidden in the minutes, contracts, and compliance records.
• Real estate purchase of commercial property - A buyer performs title verification, lien searches, and permits review to avoid undisclosed encumbrances or zoning issues that could delay or invalidate the deal.
• Foreign investment in a Mexican entity - The buyer must assess whether foreign ownership complies with Ley de Inversión Extranjera and any sector-specific restrictions that could affect control and profits.
• Data privacy and information security due diligence - A buyer inspects personal data processing practices to ensure compliance with LFPDPPP and identify exposure from data breaches or incomplete data maps.
• Intellectual property and licensing review - A target's IP portfolio, licenses, and freedom-to-operate must be validated to avoid post-transaction infringement or termination risks.
• Labor and subcontracting compliance - Employers must confirm payroll records, worker classifications, benefits, and potential labor liability under Mexican labor law.

Local Laws Overview

In Mexico, several core statutes shape due diligence practice across corporate transactions, investment, and personal data handling. The following laws are commonly engaged in comprehensive due diligence reviews.

• Ley General de Sociedades Mercantiles (LGSM) - Governs formation, governance, ownership transfers, and corporate capacity of Mexican entities such as Sociedades Anónimas and Sociedades de Responsabilidad Limitada. The LGSM also introduces mechanisms for corporate action and representations that affect closing conditions in M&A. DOF provides the official text; consolidated texts are published on gob.mx.
• Ley Federal de Protección de Datos Personales en Posesión de los Particulares (LFPDPPP) - Sets requirements for collection, storage, use, and cross-border transfer of personal data held by private entities. Due diligence in Mexico often includes mapping processing activities, evaluating consent mechanisms, and ensuring data security measures comply with INAI standards. INAI and SE provide official guidance; the law text is accessible through DOF.
• Ley de Inversión Extranjera (LIE) - Regulates foreign participation and control in Mexican economic activities, including thresholds and sectors where investment is restricted or require authorization. This law directly impacts due diligence for cross-border investments and control rights. SE offers official guidance on foreign investment frameworks and authorizations; the DOF hosts the law text.

Frequently Asked Questions

What is the purpose of due diligence in a Mexican acquisition?

Due diligence identifies legal, financial, and regulatory risks before closing a deal. In Mexico, it examines corporate structure, contracts, tax compliance, labor liabilities, and regulatory licenses. The goal is to determine value and negotiating terms based on verified facts.

How is corporate due diligence performed in Mexico during an M&A?

Typically, a data room is populated with corporate documents, contracts, and financials. Lawyers review share structures, minute books, outstanding liabilities, and compliance with LGSM requirements. A report highlights risks and recommended post-closing actions.

What documents are typically reviewed in Mexican due diligence?

Common documents include corporate bylaws, board minutes, shareholder agreements, major contracts, tax returns, payroll records, permits, licenses, IP registrations, and environmental reports. The exact set depends on deal scope and sector requirements.

How long does a typical due diligence take in Mexico?

For a mid-size deal, expect data collection in 2-3 weeks and in-depth review over 4-6 weeks. Highly regulated sectors or complex cross-border deals can extend to 8-12 weeks. Timelines depend on data room completeness and regulatory approvals.

Do I need a Mexican attorney to conduct due diligence?

Yes. Local counsel provides access to Mexican corporate records, tax filings, and regulatory databases. They ensure compliance with LGSM, LIE, and LFPDPPP, and coordinate with foreign advisors.

What is the cost range for a standard due diligence in Mexico?

Costs vary by deal size and scope but typically range from USD 15,000 to USD 100,000 for comprehensive legal due diligence. Tax, regulatory, and IP reviews increase the total; budget for third-party reports when needed.

What is the difference between financial due diligence and legal due diligence in Mexico?

Financial due diligence focuses on financial statements, revenue quality, and liabilities. Legal due diligence concentrates on corporate structure, contracts, regulatory compliance, and potential legal risks. Both are essential for a complete risk profile.

Is data privacy due diligence required under LFPDPPP in Mexico?

Data privacy due diligence is highly relevant for deals involving personal data processing. It assesses consent, data mappings, data localization, security measures, and cross-border transfers to avoid regulatory fines.

Can foreign investors perform due diligence with local counsel?

Yes. The standard practice combines foreign counsel with a Mexican law firm to address local rules and cross-border considerations. Local counsel ensures compliance with LIE and LGSM requirements.

When should due diligence start in a Mexican transaction?

Due diligence should begin after a non-disclosure agreement is signed and a letter of intent is issued. Early diligence reduces closing risk and informs price adjustments and conditions precedent.
