Laws Mexico: What Foreigners Should Know Before Visiting, Living, or Investing
Understanding laws Mexico is essential if you’re planning to visit, live, do business, or retire in the country. While Mexico is known for its warm culture, relaxed lifestyle, and vibrant cities, its legal system is structured, codified, and taken seriously. For foreigners, being aware of the country’s laws can help avoid legal troubles, ensure smooth transactions, and protect personal and financial interests.
In this guide, we cover the most important laws Mexico has in place that impact tourists, expats, business owners, and property investors. Whether you’re spending a few weeks or starting a new life in Mexico, this information will help you stay compliant and confident.
Overview of the Legal System in Mexico
Mexico follows a civil law system, meaning its laws are written and codified, rather than shaped by court precedent. The Mexican Constitution serves as the supreme law of the land, and all other laws must align with it.
There are three main levels of law in Mexico:
Federal Law: Applies nationwide, governing areas like immigration, criminal law, tax law, and corporate law.
State Law: Each of Mexico’s 32 states has its own laws, especially in areas like family law and real estate.
Municipal Law: Local regulations, such as building codes, traffic rules, and business permits.
Laws in Mexico That Tourists Should Know
For tourists, Mexican law is clear but strictly enforced. Here are a few key laws Mexico applies to short-term visitors:
Carry Proper Identification: Always have your passport and immigration documents (FMM or residency card) with you.
No Drugs: Possession of illegal drugs, even in small quantities, is a criminal offense.
Drunk Driving Laws: DUI is a serious crime in Mexico with severe penalties including jail time.
Respect Local Customs and Public Spaces: Disorderly conduct, vandalism, or disrespecting police may result in fines or arrest.
Also, be cautious when driving a rental car, as Mexican traffic laws differ from those in the U.S. or Canada, and traffic violations can result in on-the-spot fines.
Residency and Immigration Laws
Mexico provides flexible immigration options, but you must follow the proper legal channels. The main visa options include:
Visitor Visa (FMM): For stays up to 180 days, without permission to work.
Temporary Resident Visa: For stays over 180 days and up to four years.
Permanent Resident Visa: For those planning to live in Mexico long-term.
To stay compliant, you must follow procedures set by the Instituto Nacional de Migración (INM). Overstaying your visa or working without authorization is a violation of federal immigration law.

Real Estate and Property Ownership Laws
Foreigners can own property in Mexico, but there are restrictions under the laws Mexico applies to “Restricted Zones,” which include land within 50 km of the coast and 100 km of international borders.
In these areas:
Foreigners must purchase through a fideicomiso (bank trust).
The property is held by a Mexican bank on behalf of the foreign owner.
Outside the Restricted Zone, direct ownership is possible.
Using a licensed attorney and a certified notario público is required to legally transfer ownership and register the deed.
Business and Tax Laws in Mexico
Foreigners can legally open and operate businesses in Mexico. The steps include:
Choosing a legal structure (e.g., S.A. de C.V.)
Registering with the Public Registry of Commerce
Obtaining a Tax ID (RFC) from the SAT (Mexico’s tax authority)
Complying with labor, environmental, and municipal regulations
Mexico enforces strict tax laws, and all businesses must report income, issue invoices (facturas), and pay local and federal taxes. Hiring a bilingual accountant or legal advisor is highly recommended.
Criminal and Civil Laws Mexico Enforces
Foreigners are subject to the same criminal and civil laws as Mexican citizens. Some important points:
Criminal Cases: Serious offenses such as theft, assault, drug possession, and fraud can lead to detention and prosecution. Bail is not guaranteed.
Civil Cases: Issues such as property disputes, breach of contract, or inheritance are handled by civil courts, often requiring legal representation.
If you’re involved in a legal dispute in Mexico, it’s crucial to hire a qualified attorney familiar with both federal and state law.
Family and Inheritance Laws
Mexico has specific laws regarding:
Marriage and Divorce
Child Custody
Inheritance and Wills
Foreign documents like marriage certificates or wills must be translated into Spanish and apostilled to be recognized legally in Mexico. Without a proper will in Mexico, inheritance follows a strict legal order and may not go to the person you intended.
How to Stay Compliant with Mexico Laws
Here are simple steps to follow the law as a foreigner in Mexico:
Keep documents updated: Always renew visas and permits before expiration.
Follow tax and business laws: File taxes, register employees, and issue invoices legally.
Avoid illegal work: Don’t work or run a business without the proper visa or license.
Know your rights: Learn basic legal rights and responsibilities as a resident or visitor.
Hire a local attorney: A Mexican lawyer can protect your interests and represent you in legal matters.
