What a Notario Público Actually Does in Mexico
A Mexican notario is not the same as a U.S. or Canadian notary. Understanding the difference protects the buyer.
6/27/2026 · 3 min read
In the United States and Canada, a "notary" usually witnesses signatures. In Mexico, a **notario público** is a federally appointed legal officer with substantial authority over real-estate transactions.
What the notario does
- Drafts and certifies the escritura (deed).
- Calculates and collects acquisition tax (ISAI) and other closing taxes.
- Verifies that required certificates (no lien, no tax debt, water account) are in place.
- Records the deed at the public registry.
- Retains the official protocol copy of the transaction.
What the notario does NOT do
- Represent the buyer or the seller. The notario is a neutral state officer.
- Negotiate price or contract terms.
- Conduct independent due diligence on the property's history or the seller's representations.
- Provide tax planning or estate-planning advice tailored to the buyer.
Practical takeaway
A notario closing is necessary, but it is not a substitute for independent legal counsel. The notario certifies the transaction; the buyer's attorney protects the buyer.
