The short answer
In Mexico, a notary is a lawyer vested with public authority who formalizes the sale. The notary checks the title and liens, verifies identities and debts, calculates and withholds taxes, drafts the deed, signs it with the parties and records it in the Public Property Registry. That involvement gives the purchase its legal certainty.
People from other countries sometimes mistake the Mexican notary for a simple signature witness. In fact the role is central to buying property. This guide explains what notaries do, what they do not do and what to ask them. It does not replace advice from a notary.
What does the notary check before signing?
The notary requests the title history and a certificate on liens, confirms the seller owns the property and can sell it, and checks that property tax and water bills are paid. The notary also makes sure the property details match the documents.

What happens on signing day?
The notary reads the deed with the parties, verifies identities and collects signatures. With a loan, the mortgage in favor of the bank or institute is formalized in the same act. Afterwards the notary pays the taxes withheld and records the transaction in the Public Property Registry.

What does the notary not do?
A notary does not inspect the condition of the house, does not vouch for the price and does not represent only one side. To check wiring, plumbing or structure, hire an inspector; to negotiate terms, rely on your agent or lawyer.
What if the buyer is a foreigner?
The notary files the notices and permits the law requires with the Foreign Ministry (SRE). In the restricted zone, which does not include Querétaro, a bank trust is also required. Ask the notary about the specific requirements for your case and how long each step takes.

What should you ask the notary?
Bring specific questions to the first meeting to make the most of it.
- A detailed estimate of costs and taxes.
- The documents each party must provide.
- Expected timing for signing and registration.
- When you will receive your certified deed.
More detail
The recorded deed is your proof of ownership. Keep it somewhere safe with a digital copy; you will need it to sell, pass on the property or apply for loans later.
What is the certified deed and when do you get it?
The testimonio is the certified copy of the deed the notary gives the buyer once it has been recorded in the public registry. It is your formal proof of ownership.
Timing depends on the registry's workload and any pending steps. Meanwhile, the notary can issue a letter confirming the transaction is being recorded.
