Everything you need to know before buying real estate is included in our Mexico Property Pack
A notario in Mexico serves as the legal guardian of your property transaction, authenticating documents and ensuring clear title transfer, while a realtor focuses on finding properties and negotiating deals without legal authority over the transaction.
The Mexican real estate system creates a clear division of responsibilities between these two professionals, with notarios holding government-appointed legal powers and realtors operating under state licensing requirements. Understanding who does what can protect you from costly mistakes and ensure your property purchase is legally sound.

Notarios are government-appointed legal experts who authenticate property transfers, verify titles, and bear legal responsibility for transaction accuracy, while realtors are licensed professionals who assist with property selection and negotiations but have no legal authority over title verification.
As of September 2025, Mexico has 2,784 notarios across all states, with fees typically ranging from 1% to 2.5% of property value, while realtor commissions are usually paid by sellers at 5-7% of the sale price.
| Responsibility | Notario | Realtor |
|---|---|---|
| Title Verification | Legally required to verify and authenticate | No legal authority or responsibility |
| Document Preparation | Prepares all legal documents (deed, contracts) | Assists with initial paperwork only |
| Tax Clearance | Ensures all taxes and fees are paid | May coordinate but not responsible |
| Legal Liability | Civil and criminal responsibility | Limited to ethical violations |
| Registration Authority | Registers transaction with Public Registry | No registration authority |
| Appointment Method | Government-appointed by state governors | State licensing and registration |
| Buyer Fees | 1-2.5% of property value | Usually none (seller pays commission) |
What exactly does a notario in Mexico legally do for a property buyer?
A notario in Mexico serves as the ultimate legal authority in your property transaction, with powers that go far beyond what notaries do in other countries.
The notario verifies that the seller actually owns the property by conducting thorough title searches through the Public Registry of Property. They check for any liens, unpaid taxes, or legal encumbrances that could affect your ownership rights.
They prepare all essential legal documents including the escritura pública (public deed), which is the official document that transfers ownership to you. The notario also calculates and collects all applicable taxes, including acquisition taxes for buyers and capital gains taxes for sellers.
Most importantly, the notario officially registers your transaction with the Public Registry, making you the legal owner of the property. Without this registration through a notario, your purchase has no legal validity in Mexico.

What exactly does a realtor in Mexico legally do for a property buyer?
A realtor in Mexico primarily serves as your property search and negotiation specialist, but they have no legal authority over the actual transaction.
Licensed realtors help you find suitable properties, arrange viewings, and provide market insights about different neighborhoods and property values. They negotiate purchase terms on your behalf and can prepare preliminary purchase agreements.
Realtors coordinate inspections, appraisals, and connect you with other professionals like lawyers, notarios, and financial institutions. They guide you through local market procedures and cultural nuances that foreign buyers might miss.
However, realtors cannot authenticate legal documents, verify property titles, or handle any aspect of the legal transfer process. Their role ends when the notario takes over the legal formalities.
The key limitation is that realtors have no legal responsibility for title verification or transaction authenticity, which remains entirely with the notario.
How is a notario appointed in Mexico, and how many exist per state or city?
Notarios in Mexico are appointed through a rigorous government process that ensures only highly qualified legal professionals can hold these positions.
To become a notario, candidates must be Mexican attorneys with a minimum age of 35, hold a law degree, and have at least three years of experience working in a notary office. They must pass a stringent state examination that tests their knowledge of property law, civil law, and notarial procedures.
State governors make the final appointments, and notarios serve for life unless they resign or are removed for misconduct. This appointment system ensures notarios maintain independence from political pressures and commercial interests.
As of September 2025, Mexico has exactly 2,784 notarios distributed across all states. The distribution varies significantly: Mexico City has 287 notarios, Jalisco has 189, while smaller states like Baja California Sur have only 1 notario.
This limited number means notarios are in high demand, especially in popular investment areas like Playa del Carmen, Puerto Vallarta, and Mexico City, which can affect scheduling and fees.
How does a realtor in Mexico get licensed, and what regulations actually apply to them?
Realtor licensing in Mexico operates at the state level, with requirements that have become increasingly standardized across the country.
Most states now require professional diplomas in real estate, business administration, or related fields, plus documented experience in property transactions. Candidates must have clean criminal records and pass state-administered examinations.
Licensed realtors must register with state authorities and obtain tax registration (RFC) with SAT, Mexico's tax authority. They must comply with consumer protection laws, which require transparent fee disclosure and honest property representations.
Recent reforms have strengthened oversight, with states like Quintana Roo and Jalisco implementing mandatory continuing education requirements. Violations can result in license suspension or permanent revocation.
The national real estate association (AMPI) provides additional certification standards, though membership is voluntary. AMPI-certified agents typically have higher credibility and access to more comprehensive property databases.

What legal documents must a notario prepare or verify in a property sale?
The notario must prepare and verify a comprehensive set of legal documents that form the foundation of your property ownership in Mexico.
| Document Type | Purpose | Legal Requirement |
|---|---|---|
| Escritura Pública (Public Deed) | Official ownership transfer document | Mandatory for legal ownership |
| Certificado de Libertad de Gravamen | Verifies no liens or encumbrances | Required before closing |
| Tax Clearance Certificates | Proves all property taxes are current | Must be up-to-date at closing |
| Utility Clearance Certificates | Shows no outstanding utility bills | Required for clean transfer |
| Fideicomiso (if applicable) | Trust structure for foreign buyers | Mandatory for restricted zones |
| Contrato de Compraventa | Purchase and sale agreement | Legally binding contract |
| HOA Fee Clearance | Confirms no outstanding community fees | Required for condos and developments |
The notario personally verifies each document's authenticity and ensures all legal requirements are met before proceeding with the transaction.
What documents or steps does a realtor usually handle, and what do they not handle?
Realtors in Mexico handle the preliminary and coordination aspects of your property purchase, but their authority stops at the legal documentation phase.
Realtors typically prepare initial purchase offers, conduct property showings, and coordinate inspections or appraisals. They help gather basic documentation like buyer identification, proof of residence, and financial pre-qualification letters.
They create listing agreements, comparative market analyses, and preliminary purchase contracts that outline basic terms and conditions. Realtors also coordinate between buyers, sellers, and their respective representatives.
However, realtors cannot prepare the escritura pública, verify legal title, conduct official lien searches, or authenticate any legal documents. They cannot collect taxes, register transactions, or handle fideicomiso paperwork.
The critical distinction is that realtors work with preliminary agreements and coordination, while all legally binding documentation must go through the notario.
Who checks if the seller actually owns the property and if there are liens or debts on it?
The notario bears the exclusive legal responsibility for verifying property ownership and checking for liens or debts in Mexico's real estate system.
Notarios conduct comprehensive title searches through the Public Registry of Property, examining the complete ownership history of the property. They verify that the seller's name matches the registered owner and that no unauthorized transfers have occurred.
They obtain and review the Certificado de Libertad de Gravamen, which shows any liens, mortgages, or legal encumbrances on the property. This certificate must be current, typically issued within 30 days of the closing.
The notario also checks for unpaid property taxes, utility bills, and HOA fees that could become the buyer's responsibility. They review court records to ensure no legal disputes or judgments affect the property.
This verification process is legally binding, and the notario faces civil and criminal liability if they fail to identify existing liens or ownership problems that later affect the buyer.
Who ensures the property taxes and utility bills are cleared before the sale closes?
The notario has the legal obligation to ensure all property taxes and utility bills are fully paid before completing the sale.
Before closing, the notario requires the seller to provide current tax receipts showing no outstanding property taxes (predial). They verify payments with municipal authorities and ensure any past-due amounts are settled.
For utilities, the notario demands clearance certificates from water, electricity, and gas companies showing zero outstanding balances. This includes reviewing recent bills and ensuring service transfers can occur without debt obligations.
If the property is in a condo or planned community, the notario verifies that all HOA fees, maintenance charges, and special assessments are current. They obtain written confirmation from the homeowners association.
The notario will not proceed with the transaction until all clearance certificates are provided and verified. This protection ensures buyers don't inherit the seller's unpaid obligations.

What fees do buyers pay to the notario, and what's the typical percentage of the property value?
Notario fees in Mexico typically range from 1% to 2.5% of the property's purchase price, representing one of the most significant closing costs for buyers.
The fee structure usually includes a base notarial fee plus government taxes and registration costs. For a $200,000 property, buyers can expect to pay between $2,000 and $5,000 in total notario-related expenses.
Higher-value properties often see fees toward the lower end of the percentage range, while smaller transactions may approach the 2.5% maximum. Notarios in tourist areas like Cancún and Puerto Vallarta typically charge premium rates due to higher demand.
These fees cover title research, document preparation, tax calculations, legal verification, and official registration with the Public Registry. Additional costs may include translation fees for foreign buyers and expedited processing charges.

What commissions or fees do buyers indirectly pay through the realtor, and how much are they usually?
Mexican real estate follows the standard practice where sellers pay realtor commissions, but buyers indirectly bear these costs through higher property prices.
Total realtor commissions typically range from 5% to 7% of the sale price, split between the listing agent (representing the seller) and the buyer's agent. In Mexico City and resort areas, commissions often reach the higher end of this range.
For a $300,000 property, the total commission could be $15,000 to $21,000, which sellers factor into their asking price. Buyers effectively pay this through the inflated property cost.
Some realtors charge buyers directly for specialized services like property management setup, legal referrals, or extensive market research. These fees are typically $500 to $2,000 and should be disclosed upfront.
Buyers working with buyer's agents who double-end transactions (representing both parties) may see slightly reduced overall costs, but this arrangement can create conflicts of interest.
If something goes wrong with the title or ownership later, who is legally accountable, the notario or the realtor?
The notario bears full legal accountability for title and ownership issues that arise after the sale, while realtors have very limited liability.
Notarios face both civil and criminal responsibility if title defects result from their negligence or failure to conduct proper verification. They can be sued for damages and face professional sanctions including loss of their appointment.
Mexican law specifically assigns title verification responsibility to notarios, making them liable for errors in ownership documentation, missed liens, or faulty registration processes. Their professional insurance and bonding requirements reflect this significant liability.
Realtors are only liable if they knowingly misrepresented property ownership or participated in fraudulent schemes. Their responsibility is limited to ethical violations rather than technical title defects.
This legal framework means buyers should focus on choosing reputable notarios with strong track records, as they are your primary protection against ownership problems.
What steps can a buyer take in Mexico to protect themselves beyond relying on the notario or the realtor?
Smart buyers in Mexico implement multiple layers of protection beyond the standard notario and realtor services.
- Hire an independent attorney: Engage a lawyer who represents only your interests, separate from the notario who serves both parties in the transaction.
- Conduct personal title research: Review property records at the Public Registry yourself or through your attorney to verify the notario's findings.
- Verify professional credentials: Confirm your notario's appointment status with state authorities and check your realtor's license through state regulatory bodies.
- Obtain comprehensive insurance: Purchase title insurance if available, and ensure adequate property insurance coverage starts immediately upon closing.
- Document everything: Maintain copies of all receipts, certificates, and communications. Insist on written confirmations for all verbal agreements.
- Use escrow services: For large transactions, consider using established escrow companies to hold funds until all conditions are met.
- Get second opinions: For expensive properties, consider having another notario review the documentation as a quality check.
