You've found the right property. The purchase agreement is signed. Financing is arranged. Now you're sitting across from a notario público who will execute the most important transaction of your Mexican property journey. This isn't a formality—this legal professional holds more authority over your transaction than any other party involved, including your real estate agent, your attorney, and even the seller.
Unlike notaries in the United States or Canada who simply witness signatures, a notario público in Mexico is a government-appointed attorney with the legal power to verify property titles, calculate and collect taxes, draft your escritura (property deed), and register your ownership in the Public Property Registry. No real estate transaction in Mexico is legally valid without a notario's involvement. Understanding what questions to ask—and why those questions matter—transforms this meeting from a passive signing session into an active protection of your investment.
Understanding Your Notario's Extraordinary Authority
Before exploring specific questions, international buyers need to understand just how much legal power Mexican notarios hold. According to the Texas Secretary of State, the differences between Mexican notarios and U.S. notaries are so profound that Texas law specifically prohibits translating "Notary Public" literally into Spanish to prevent confusion.
A notario público in Mexico:
Must be a licensed attorney with minimum five years of legal practice experience
Appointed by the state governor after passing rigorous examinations
Holds personal legal liability for every transaction they execute (civil and criminal)
Cannot be replaced once appointed—their number is strictly limited by population
Serves as legal advisor, tax collector, and government representative simultaneously
Signs documents with "Doy Fe" (I Give Faith)—a personal guarantee of legal validity
This isn't someone who simply watches you sign papers. This is the legal professional who determines whether your transaction can proceed, whether title is clear enough to transfer, and whether all legal requirements have been satisfied. Your notario's signature is what makes your ownership legally enforceable.
While your notario is an experienced attorney, they represent three parties equally: you (the buyer), the seller, and the Mexican government. They do not function as "your lawyer" exclusively. Many international buyers choose to hire independent legal counsel for personalized advice, but the notario alone has the authority to execute the transaction and register your ownership.
Essential Questions About Title Verification
Your notario's most critical responsibility is confirming that the seller has clear, legal title to transfer. These questions ensure that verification happens thoroughly.
Has the complete title search been performed?
Ask your notario to confirm they've conducted a full title search through the Registro Público de la Propiedad (Public Property Registry) covering at least the past 10 years. This search identifies any liens, encumbrances, unpredictable claims, or legal disputes attached to the property.
Why this matters: Title problems discovered after closing become your problem. The notario's search is your primary protection against inheriting someone else's legal complications.
Is this property registered in the Public Property Registry or the National Agrarian Registry?
This single question protects you from the most common and costly mistake international buyers make: purchasing ejido land that foreigners cannot legally own.
Why this matters: Property in the Public Registry is private property available for foreign purchase. Property in the Agrarian Registry is communal ejido land that Mexican law prohibits foreigners from owning under any circumstances. Your notario must confirm registration in the correct registry.
Has the Certificado de Libertad de Gravamen been issued?
Request to see the Certificado de Libertad de Gravamen—the official certificate confirming the property is free from liens, mortgages, and other encumbrances.
Why this matters: This document proves no one else holds legal claims against the property. Without it, you could inherit debts, mortgages, or legal judgments that the previous owner failed to disclose.
Request copies of all verification documents your notario reviews—not just verbal confirmation. Professional notarios expect this request and will provide documentation showing their due diligence. If your notario resists providing verification documents, this is a red flag warranting additional independent legal review.
Questions About Your Ownership Structure
For international buyers, how you hold title matters as much as whether you hold title. These questions confirm your ownership structure is properly established.
Am I purchasing through fideicomiso or fee simple ownership?
Your notario should clearly explain which ownership structure applies based on your property's location. Fee simple ownership (direct title) applies to properties outside restricted zones, while fideicomiso (bank trust) is required within 50 km of coastlines or 100 km of borders.
Why this matters: Most Bajío properties qualify for fee simple ownership, avoiding ongoing trustee fees and 50-year renewal requirements. Confirming your structure helps you budget correctly and understand your long-term ownership obligations.
If fideicomiso is required, which bank will serve as trustee?
If your property requires a fideicomiso, ask which Mexican bank your notario recommends as trustee and what their annual fees are.
Why this matters: Trustee fees vary by bank ($500-$700 USD annually). Understanding these costs upfront prevents surprises and allows proper financial planning.
How will my ownership be registered in the escritura?
Confirm exactly how your name will appear on the property deed—individual ownership, joint ownership with rights of survivorship, or through a Mexican corporation if applicable.
Why this matters: How ownership is registered affects inheritance rights, tax treatment, and your ability to sell or transfer the property in the future. Errors in the escritura are expensive and time-consuming to correct after registration.
Tax Calculation and Payment Questions
Your notario calculates and collects all taxes related to your transaction. These questions confirm accurate calculation and proper payment.
What taxes am I responsible for paying at closing?
Request a detailed breakdown of all taxes and fees you'll pay, including:
- Property acquisition tax (typically 2-4% of purchase price, varies by state)
- Capital gains tax (paid by seller, but confirm payment to protect yourself)
- Notario fees (usually 1% of transaction value)
- Public Registry registration fees
- Appraisal costs (required for tax calculation)
Why this matters: Understanding total closing costs before signing prevents last-minute surprises and confirms you've budgeted adequately for all required payments.
Has the seller paid all property taxes (predial) through the current date?
Confirm your notario has verified the seller paid all predial (property taxes) and utility bills through the closing date, with documentation proving payment.
Why this matters: Unpaid property taxes become your responsibility after ownership transfers. Verification protects you from inheriting the seller's tax debt.
What is the appraised value used for tax calculation?
Ask what property valuation your notario used to calculate your acquisition taxes, and whether that appraisal seems reasonable compared to your purchase price.
Why this matters: In Mexico, notarios must order official appraisals to calculate taxes. Understanding this valuation confirms appropriate tax calculation and identifies potential discrepancies between appraised and purchase values.
Key Questions Checklist
Before You Sign, Confirm:
Complete title search conducted covering minimum 10 years
Property registered in Public Property Registry (not Agrarian Registry)
Certificado de Libertad de Gravamen issued showing no liens
Ownership structure clearly explained (fideicomiso or fee simple)
All taxes and fees itemized with clear payment schedule
Seller's property taxes paid through closing date
Escritura reviewed before signing for accuracy
Registration timeline provided for Public Property Registry
Questions About the Transaction Timeline
Understanding timing helps you plan appropriately and know what to expect after signing.
How long will the registration process take?
Ask your notario for a realistic timeline from signing to final registration in the Public Property Registry.
Why this matters: Registration typically takes 30-60 days in the Bajío region but can vary by municipality. Knowing the timeline helps you plan when you'll have full legal ownership documentation.
When will I receive my registered escritura?
Confirm when you'll receive your official property deed with registration stamps from the Public Property Registry.
Why this matters: Your registered escritura is your proof of ownership. Until you have this document, your transaction isn't fully complete.
What happens if problems arise during registration?
Ask what steps your notario takes if the Public Property Registry identifies issues during the registration process.
Why this matters: Reputable notarios resolve registration problems as part of their service. Understanding their problem-resolution process confirms you're working with an experienced professional.
Notario Selection and Vetting in the Bajío Region
While sellers often work with specific notarios they trust, Mexican law gives you—the buyer—the right to choose which notario handles your transaction. This is an important right that protects your interests.
Working with Recommended Notarios
In practice, most international buyers in the Bajío work with notarios recommended by their real estate agent or attorney. This typically works well because experienced agents maintain relationships with reputable notarios who understand foreign buyer needs and provide bilingual service.
However, you should still:
- Ask about the notario's experience with international transactions
- Confirm they provide bilingual support if you don't speak fluent Spanish
- Request references from other foreign buyers they've assisted
- Understand their fee structure before committing to work with them
Red Flags That Warrant Additional Legal Review
Consider hiring independent legal counsel if your notario:
- Resists providing verification documentation you request
- Cannot clearly explain title issues or ownership structure
- Rushes you to sign without adequate time to review documents
- Provides only Spanish documents without translation for non-Spanish speakers
- Has difficulty answering basic questions about the transaction
In San Miguel de Allende and surrounding Bajío towns, there are typically only 8-12 practicing notarios serving the entire region. This limited number means notarios are highly sought after, and securing appointments requires patience. However, this exclusivity also means notarios must meet rigorous government standards and maintain impeccable reputations to retain their appointments.
Common Questions About Working with Notarios
Not required, but many international buyers choose to hire independent legal counsel for personalized advice. While your notario is an experienced attorney, they represent all parties and the government equally. An independent lawyer represents only your interests and can review documents before you sign with the notario.
Many notarios in the Bajío region provide bilingual services or work with translators for international clients. Confirm language support before your signing appointment. If your notario doesn't provide translation, bring your own qualified translator or independent attorney who speaks both languages.
Yes. Mexican law gives buyers the right to choose their notario. However, switching notarios mid-transaction may delay closing and require repeating some verification work. If you have concerns about the recommended notario, address them early in the process before substantial work begins.

The questions outlined in this guide transform your notario meeting from a passive signing session into an active confirmation that every verification step has been completed properly.
