If you're buying property in Los Cabos, one of the most important people at your closing isn't an agent or a lender. It's the notario público, a role that looks very different from a notary in the United States or Canada. Understanding what the notario does can make the process feel far more predictable. Here's how I explain the role of the notario público in Mexico real estate transactions to the buyers and sellers I work with.

Key Takeaways

  • A notario público is a licensed attorney appointed by the state to oversee property sales.
  • The notario drafts the deed, or escritura, and registers it with the Public Registry.
  • The notario calculates and pays the seller's federal income tax on the sale.
  • Foreign buyers in Los Cabos typically purchase through a bank trust, or fideicomiso.

What a Notario Público Is

In the United States and Canada, a notary public mainly verifies signatures. In Mexico, a notario público is a licensed attorney who has passed a notarial exam and been appointed by the state governor.

Notarios must also belong to their state's Colegio de Notarios, which provides professional oversight. That combination of legal training and state appointment is what gives the role its authority in a real estate sale.

How a Notario Público Differs From a U.S. Notary

  • Must hold a law degree and be a licensed attorney
  • Must pass a notarial exam before appointment
  • Is appointed by the state governor
  • Oversees the legality of the transaction, not just signatures

Why Every Sale Goes Through a Notario

In a Mexican property sale, the notario writes the deed, known as the escritura. A transaction isn't considered complete until the notario has prepared that deed and the parties have signed it.

The notario acts as a neutral party for both buyer and seller, verifying identities and confirming the legality of the sale. Once the deed is signed, the notario registers it with the Public Registry of Property, making the transfer part of the official record.

What the Notario Handles at Closing

  • Reviewing the identities and legal capacity of both parties
  • Drafting the escritura for signature
  • Witnessing signatures as an impartial party
  • Registering the deed with the Public Registry of Property

Taxes and Closing Documents

Taxes are one of the notario's most important responsibilities. Under Mexico's federal income tax law, the notario calculates the seller's income tax on the sale, when it applies, and pays it to the tax authorities within 15 days after the deed is signed.

Buyers pay a local acquisition tax as well, which in Baja California Sur, including Los Cabos, is currently 3% of the property's taxable value. Supporting documents such as a property appraisal and a certificate of no liens from the Public Registry are also part of preparing for closing.

Documents and Taxes to Expect

  • The seller's federal income tax, calculated and paid through the notario
  • The buyer's acquisition tax, currently 3% in Baja California Sur
  • A certified property appraisal
  • A certificate of no liens confirming the property is free of encumbrances

Foreign Buyers and the Fideicomiso

Mexico restricts direct foreign ownership of property within 50 kilometers of the coast and 100 kilometers of its borders. Because Los Cabos sits at the tip of the Baja Peninsula, foreign buyers here typically purchase through a bank trust, or fideicomiso.

In a fideicomiso, a Mexican bank holds legal title while you hold the right to use, enjoy, and rent the property. The trust requires a permit from Mexico's Ministry of Foreign Affairs, can last up to 50 years, and can be renewed.

Key Points About the Fideicomiso

  • A Mexican bank serves as trustee and holds legal title
  • You, as beneficiary, can use, enjoy, and rent the property
  • The trust requires a permit from the Ministry of Foreign Affairs
  • The term can last up to 50 years and is renewable

Preparing to Work With a Notario

Buyers generally pay the notario's fees and have the right to choose the notario, often with input from the transaction coordinator. I recommend asking questions early so you understand the timeline, costs, and documents involved.

The escritura is written in Spanish, so it's worth arranging an interpreter or translated summary if you aren't fluent. Planning ahead helps closing day go smoothly, whether you attend in person or close remotely.

Tips for a Smooth Closing

  • Ask about the notario's fees and timeline early
  • Gather identification and any documents requested in advance
  • Arrange an interpreter or translation if you need one
  • Ask when you'll receive your recorded deed or trust documents
