Buying property in Mexico means encountering a vocabulary that has no exact equivalent in the English-speaking real estate world. A notario is not a notary in the American sense; a fideicomiso is not a standard trust; an escritura is more than a deed. Misunderstanding these terms is not a small language problem — it can lead to signing the wrong document, missing a critical step, or misjudging your rights. This glossary translates and explains the terms you are most likely to meet, grouped by where they appear in the buying journey. Read it once before you start, and keep it nearby when the paperwork arrives.
The People and Documents at Closing
Escritura — The formal, notarized property deed. It is the legal instrument that records ownership and is prepared and authorized by a notario. When people say a purchase is “not yet on the escritura,” they mean the transfer has not yet been formalized. This is the document that proves you own the property.
Notario público — A notary public, but far more powerful than the North American version. A notario is a state-appointed attorney with authority to formalize deeds, verify legality, calculate and collect certain taxes, and register the transaction. Most property sales must be formalized before a notario. They are neutral, act on behalf of the transaction’s legality, and carry significant professional responsibility.
Poder notarial — A power of attorney. It authorizes another person to act in your name — for example, to sign a deed if you cannot be present. It can be general or limited to a specific act, and foreign buyers often use a limited one to purchase remotely.
Fe de hechos — A notary’s certified statement of facts they have witnessed, sometimes used to document the condition of a property or an event at a point in time.
Ownership Structures for Foreigners
Fideicomiso — A bank trust used by foreign buyers to hold residential property within the zona restringida (see below). A Mexican bank holds legal title as trustee, while you, the beneficiary, hold all the rights of ownership: to use, rent, improve, sell, and pass on the property. It is a well-established, secure mechanism — not a lease and not a loss of control — created because the constitution limits direct foreign ownership near coastlines and borders.
Zona restringida — The restricted zone: land within roughly 50 kilometers of the coast or 100 kilometers of a border. Foreigners generally acquire residential property here through a fideicomiso or, for certain purposes, a Mexican corporation.
Beneficiario — The beneficiary of a fideicomiso: you, the buyer, who holds the practical rights to the property while the bank holds title as trustee.
Copropiedad — Co-ownership, where two or more people jointly own a property, each with a defined share.
Régimen de condominio — Condominium regime, the legal structure governing properties divided into privately owned units with shared common areas, including the rules and fees that come with it.
Taxes and Costs
Predial — The annual property tax, paid to the municipality. It is generally modest compared with property taxes in many other countries. Proof that the predial is paid current is a standard part of due diligence, because unpaid amounts can become a claim against the property.
ISR (Impuesto Sobre la Renta) — Income tax, which in real estate most often arises as a tax on the capital gain when a property is sold. Sellers, not buyers, typically face it, but buyers should understand it because it affects negotiations and the seller’s willingness to document a true sale price.
ISAI / Impuesto de Adquisición — The acquisition or transfer tax paid by the buyer when property changes hands, calculated as a percentage of the transaction value and collected at closing. Its exact name varies by state.
IVA (Impuesto al Valor Agregado) — Value-added tax. It generally does not apply to the sale of residential dwellings but can apply to commercial property and to certain services and construction.
Avalúo — A formal appraisal of the property’s value, prepared by an authorized appraiser. It is used to calculate taxes and, where financing is involved, to support the loan. The avalúo value and the agreed price are not always identical.
Verification and Due Diligence
Registro Público de la Propiedad — The Public Registry of Property, the government office that records ownership and legal claims on real estate. Much of your due diligence traces back to what this registry shows.
Certificado de Libertad de Gravamen — A certificate confirming the property is free of encumbrances — mortgages, seizures, easements — as of its date of issue. Issued by the Public Registry, it is a core check before closing.
Gravamen — An encumbrance: any recorded claim or restriction on a property, such as a hipoteca (mortgage) or embargo (seizure), that travels with the land regardless of who owns it.
Uso de suelo — Land use / zoning, the municipal designation that determines what you may legally do with a property: residential, commercial, tourist, mixed, and so on. Verified through a constancia de uso de suelo.
Deslinde — A boundary survey performed by a topógrafo (surveyor) to confirm a property’s true dimensions and its colindancias — its boundaries with neighboring parcels — against what the deed claims.
Colindancias — The adjoining boundaries and neighbors of a parcel, as described in the deed and confirmed on the ground.
Land Types and Special Cases
Ejido — Communally held land, a form of collective landholding rooted in agrarian reform. Ejido land is subject to special rules and generally cannot be sold as ordinary private property unless it has been formally converted to private title (dominio pleno) through the proper legal process. Buying ejido land that has not been correctly regularized is one of the classic traps for uninformed buyers — treat any such property with serious caution and independent legal review.
Dominio pleno — Full private ownership title, the status ejido land must reach through a formal process before it can be freely bought and sold as private property.
Terreno — Land or a lot, as distinct from a built structure.
Catastro / Clave catastral — The cadastre and the property’s cadastral key, the municipal system and identifier used for tax and mapping purposes.
Common Contract Terms
Contrato de compraventa — The purchase-and-sale agreement between buyer and seller, which sets the terms before the formal escritura is signed before the notary.
Enganche — The down payment or deposit made toward a purchase.
Arras — Earnest money or a deposit that signals commitment to the deal, sometimes with agreed consequences if either side backs out.
Promesa de compraventa — A promise or preliminary agreement to buy and sell, committing the parties to complete the transaction under stated terms.
Using This Glossary Well
A vocabulary list is a starting point, not a substitute for advice. The terms above will help you follow conversations, recognize the documents that matter, and ask sharper questions — but two of these words in particular, fideicomiso and ejido, carry enough weight that you should always have an independent lawyer confirm how they apply to your specific purchase. Language fluency is not the same as legal certainty. Learn the terms so you know what is happening; rely on qualified professionals to make sure it happens correctly. When a document uses a word you do not fully understand, stop and ask before you sign — in Mexican real estate, the meaning of a single term can define the whole deal.
