Quick Answer
A notario publico is a government-appointed attorney who supervises all real estate transactions in Mexico. Unlike a US notary, a Mexican notario is a highly qualified lawyer with the authority to authenticate documents, calculate taxes, register deeds, and legally bind transactions. The notario represents the buyer, seller, and government simultaneously.
Detailed Answer
A notario publico is a government-appointed legal professional who plays a central role in every real estate transaction in Mexico. Unlike a notary public in the United States (who simply witnesses signatures), a Mexican notario is a fully licensed attorney with the authority to authenticate documents, calculate and collect taxes, register property deeds, and ensure the transaction complies with all federal and state laws. There are only a limited number of notarios authorized in each jurisdiction, making them highly vetted professionals.
During a real estate closing, the notario verifies the seller's ownership, confirms there are no liens or encumbrances, prepares the escritura (deed), calculates the acquisition tax (ISAI) and other fees, and files the transaction with the Public Registry. The notario acts as a neutral party representing the interests of the buyer, seller, and the Mexican government simultaneously. This is why hiring an independent attorney is also recommended — to protect your specific interests.
