What a fideicomiso legally is
Article 381 of the Ley General de Títulos y Operaciones de Crédito defines it this way: "By virtue of the fideicomiso, the settlor transfers to a fiduciary institution the ownership or title of one or more assets or rights [...] to be allocated to lawful, specific purposes." Applied to real estate in the restricted zone, that lawful purpose is a single one: giving a foreigner legal, secure access to a property that Article 27 of the Constitution does not let them own directly within 50 km of the coastline.
Transfers the property to the trustee to set up the trust.
The legal owner before the Public Registry, but only administers — it cannot use, rent or sell the property on its own.
You hold every real right to use, rent, sell, improve and bequeath the property.
The myths to clear up first
"The bank owns my house."
The fiduciary bank appears as legal titleholder before the Public Registry, but it only administers the trust per the contract. It cannot sell, rent, occupy or dispose of the property on its own initiative — every action requires your authorization.
"The fideicomiso is a legal loophole, almost a gray area."
It is exactly the opposite: it is the mechanism the Constitution and the Foreign Investment Law themselves designed to resolve the Article 27 restriction in the coastal zone. It is not a workaround — it is the official route.
"I don't really own it, I just have a permit to use it."
As beneficiary you hold a bundle of rights nearly identical to direct ownership: living in it, renting it, selling it and capturing the appreciation, pledging it as mortgage collateral, and bequeathing it. The only thing that changes is who appears as titleholder in the registry.
"It's the same as a long-term rental."
No. Renting builds no equity and no inheritable asset for you. With the fideicomiso, the property's value is yours: you capture it when you sell, pass it to your beneficiaries, and can use it as collateral — none of that exists in a lease.
Your real rights as beneficiary
- Live in the property or leave it vacant, without restriction.
- Rent it out — including short-term/Airbnb-style rental, unless the condo bylaws or the trust contract itself restrict it.
- Sell it at any time and keep the gain (minus the applicable ISR).
- Pledge it as mortgage collateral to obtain financing.
- Improve, remodel or build on it, subject to normal municipal permits.
- Bequeath it to whoever you designate as a substitute beneficiary in the trust contract itself.
How it is set up, step by step
1. Choose the fiduciary bank
There is no obligation to use the bank the seller or agency suggests. Get quotes from 2–3 banks active in the area (see the list below) before deciding.
2. Apply for the SRE permit
The bank or notary requests the permit from the Secretaría de Relaciones Exteriores to set up the trust. Official cost $21,648.83 MXN, published turnaround of 5 business days.
3. Title due diligence
The notary checks the history at the Quintana Roo Public Registry of Property and confirms there are no liens before the trust is set up.
4. Signing the trust contract
The notary drafts and certifies the contract, which defines from the start who the substitute beneficiaries are in the event of the titleholder's death.
5. Registration and handover
The trust is recorded at the Public Registry of Property and the bank delivers the beneficiary a certified copy of the contract — the document that proves your rights.
Real, complete costs
≈$1,100–1,200 USD. Official 2026 rate, Article 25 of the Federal Duties Law.
Wide range because two specialized sources quote different figures ($500–1,000 USD one, $800–2,200 USD equivalent the other); banks do not publish rate sheets and quote case by case.
Figure that converges across 3 independent sources — the most reliable in this table.
Fiduciary commissions are not on the exempt list in Article 15 of the IVA Law, so the general 16% rate applies. Confirm with your bank whether their quote already includes it.
Charged once, when the property enters the trust — it is the same ISAI as any purchase, not an extra charge for using a fideicomiso.
Active fiduciary banks named by real estate advisories in 2026: Multiva, Kapital Bank, Banorte, Monex, Mifel, Scotiabank, Actinver and Banco del Bajío. None publish an online rate sheet — get quotes from 2–3 before choosing.
Predial (0.1–0.3% of value per year) and ISR on sale are charged the same as in any purchase — they are not extra fideicomiso charges.
The 50-year term: routine if you tend to it, real if you don't
The fideicomiso is set up for 50 years and is renewable indefinitely in equal periods. The bank typically gives notice 1–2 years before expiration, and renewing is a simple administrative step, not a repurchase.
The real risk if you let it lapse
If you genuinely let the term lapse without renewing, the law requires the property to transfer to a Mexican national — this is not a theoretical warning. Keep your contact details current with the bank and mark the expiration date on your own calendar, don't rely solely on the bank's notice.
What if the fiduciary bank fails or is taken over?
Trust assets are legally segregated from the bank's own balance sheet — they are not part of its assets in a failure or takeover. This already happened in 2025: when CIBanco and Intercam were taken over by the regulator, their entire fideicomiso portfolios were sold — CIBanco's to Banco Multiva and Intercam's to Kapital Bank — without owners losing any rights. A banking crisis does not put your property at risk, though it can mean paperwork to transfer the file to the new trustee.
Selling or assigning your rights
You can sell at any time, even before the 50-year term ends, through a cesión de derechos fideicomisarios (assignment of beneficiary rights): the notary ratifies instruction letters between you, the buyer and the bank, and the same trust continues in force with the new beneficiary — there is no need to set up a new one from scratch. The ISR on the sale is calculated the same as in any purchase (see our legal framework guide for the exact rates).
Pending verification: we did not find a source explicitly confirming whether an assignment requires a new SRE permit or whether the original permit remains valid for the new beneficiary. Confirm this directly with your notary before a sale.
What happens if the titleholder dies
This is the most commonly misunderstood point: the transfer of property held in fideicomiso is governed by the beneficiary designation inside the trust contract itself — not your will from your home country, Mexican or foreign. If you never designated a substitute beneficiary, or your family situation changed and you never updated the contract, the transfer process becomes long and costly for your heirs.
For US buyers: the US federal estate tax only applies to estates above several million dollars — the vast majority of buyers of a single vacation property fall well below that threshold. Even so, consult a lawyer experienced in cross-border estates for your specific situation.
What this means for your decision
Designate substitute beneficiaries on the day you sign, don't leave it for later. And if you marry, divorce or your family situation changes, go back to the notary to update the contract — it is far cheaper than a transfer process with no clear designation.
What if I have or plan to have several properties?
For a single property for personal or vacation use, the fideicomiso is the simplest and cheapest option. If you are thinking about three or more properties, or a rental business at scale, it is worth comparing against a Mexican corporation (S.A. de C.V.) — we cover that comparison in depth, with RFC, accounting and fee-savings figures, in our legal framework and ownership guide.

Can the bank sell my house without telling me?
No. The trustee acts only on your written instruction, per the contract. It has no authority to dispose of the property on its own.
Do I lose the property if the fiduciary bank fails?
No. Trust assets are legally segregated from the bank's own balance sheet — they are not part of its assets in a failure. This already happened in 2025 with CIBanco and Intercam: their portfolios were sold in full (to Multiva and Kapital Bank) without owners losing any rights.
Can I rent it out on Airbnb?
Generally yes — it is a beneficiary right. Check the condo bylaws and the trust contract itself, since some limit short-term rentals or major remodeling.
What happens if I don't renew the 50-year term on time?
The bank typically gives 1–2 years' notice and renewal is a simple administrative step. But if you genuinely let the term lapse without renewing, the law requires the property to transfer to a Mexican national — a real risk, not just a theoretical one, so don't let it slip.
What happens if I die as the titleholder?
The transfer is governed by the beneficiary designation inside the trust contract itself — not your will from your home country. If you never designated a substitute beneficiary, the process becomes long and expensive. Set it at signing and update it if your plans change.
Can I sell or assign my rights before the trust ends?
Yes, at any time, through a cesión de derechos fideicomisarios (assignment of beneficiary rights): the notary ratifies the instruction between you, the buyer and the bank, and the same trust continues with the new beneficiary — there is no need to set up a new one from scratch. Confirm with your notary whether your case needs any additional SRE filing.
The fideicomiso does not take away legal security — it gives it to you. It is the mechanism Mexican law itself designed so a foreigner can own with the same peace of mind as a Mexican citizen in the coastal zone.
