Property Inheritance Laws in Cozumel: 2026 Estate Planning

A named substitute beneficiary normally starts succession by notifying the trustee, submitting the death certificate, identity documents, apostilles, translations, and bank forms, then signing the substitution instrument. The trust-held property may avoid probate, but the bank, notary, registry, and tax steps still must be completed.

Key Takeaways

• Cozumel lies within Mexico's restricted zone, requiring foreign residential ownership through a fideicomiso; naming primary and substitute beneficiaries in the trust deed is the single most important estate-planning action a foreign owner can take.
• A properly maintained fideicomiso succession clause allows the beneficial interest to pass directly to heirs outside formal probate, while direct-title property or a missing beneficiary designation triggers court-supervised intestate or testamentary proceedings.
• Mexico imposes no federal inheritance or estate tax, but heirs may face a local acquisition tax (ISAI), future capital-gains tax when selling, ongoing predial, and home-country estate-tax and reporting obligations.
• A US or Canadian will does not automatically transfer Mexican real estate; a separate Mexican will, executed before a notary in Quintana Roo, is recommended to cover direct-title assets and clarify intent for the fideicomiso property.
• Practical costs include trustee substitution, notary, apostille, translation, registry, appraisal, and legal fees, totaling several thousand US dollars and taking three to twelve months to complete.

At a Glance: Cozumel Inheritance by Ownership Structure (2026)

What Happens to a Cozumel Property When a Foreign Owner Dies?

When a foreign owner of Cozumel property dies, the beneficial interest transfers directly to the named substitute beneficiary upon presentation of a death certificate, identity documents, apostilles, and translations to the trustee bank, avoiding Mexican probate for that property, whereas property without a designated heir enters formal probate under Quintana Roo law.

Because Cozumel lies within 50 kilometers of the coast, it sits squarely in Mexico's restricted zone, and foreign residential buyers generally cannot hold direct title. Instead, a Mexican bank holds legal ownership as trustee under a fideicomiso, while the foreign beneficiary retains every practical and economic right—use, rental income, sale, remodeling, and crucially, the right to designate who receives those rights upon death. This structure, mandated by Article 27 of the Mexican Constitution (see Secretaría de Relaciones Exteriores), becomes the foundation of estate planning for foreign owners across the island.

When I walk clients through fideicomiso estate planning, I always stress that the substitute-beneficiary clause is not optional paperwork—it is the entire succession mechanism. If you name your spouse, children, or another qualified individual as the substitute beneficiary in the original trust deed or through a subsequent amendment, the trustee bank can transfer beneficial control without involving a Mexican court. If you leave that line blank or never update it, your heirs face the same probate process as if you owned the property outright.

The fideicomiso permit itself is issued for 50 years and may be renewed indefinitely for additional 50-year terms, so the trust can span generations if properly maintained. The substitute beneficiary steps into the deceased beneficiary's position and inherits the remaining term, the trustee relationship, the annual administration fee obligation, and all property rights.

Direct-title property—found inland, outside the restricted zone—passes according to a Mexican will if one exists, or through intestate succession if it does not. A foreign will can dispose of Mexican real estate in principle, but enforcing it requires recognition by a Mexican court or notary, translation, apostille, and often a lengthy process that a local will avoids. For the broader rules on Cozumel property law and taxes, see our guide before signing a purchase contract.

The death of a fideicomiso beneficiary does not terminate the trust, suspend property rights, or freeze the asset. Utilities, predial, condominium fees, insurance, and trustee annual charges continue, and someone—typically the estate executor or a family member—must keep those current during the transition to avoid liens, penalties, or service interruptions.

Why Cozumel Uses a Fideicomiso

Cozumel requires foreign residential buyers to use a fideicomiso because the island lies entirely within Mexico's constitutional restricted zone, defined as any land within 50 kilometers of the coastline, where direct foreign ownership of real estate is prohibited under Article 27 of the Mexican Constitution.

The fideicomiso structure, formalized in the 1970s and administered by Mexico's Ministry of Foreign Affairs (Secretaría de Relaciones Exteriores, SRE), allows a Mexican bank to hold legal title as trustee while the foreign buyer becomes the first beneficiary, enjoying full use, rental income, remodeling rights, sale authority, and the power to name heirs. The restriction applies to residential property; commercial or industrial real estate may be owned directly by a Mexican corporation with foreign shareholders, subject to SRE authorization. For the vast majority of foreign buyers, the fideicomiso is the usual structure for foreign residential ownership in the restricted zone and has become the accepted standard across Quintana Roo's coast, including Playa del Carmen, Tulum, and the islands.

From an estate-planning perspective, the fideicomiso offers a significant advantage: because the bank holds title and the beneficiary holds only contractual rights, the substitution of one beneficiary for another is an administrative amendment to the trust deed rather than a transfer of real property requiring court approval, potentially bypassing probate entirely for the property held in the trust.

The permit is valid for 50 years from the date of issuance and renewable indefinitely in 50-year increments, meaning a properly managed fideicomiso can remain in effect across multiple generations. The annual trustee fee—typically between USD 450 and USD 800 (market guide, September 2026)—covers administration, reporting, and coordination with the Public Registry of Property. Setup costs in 2026 include a government permit fee of approximately MXN 21,649 (about USD 1,200) plus the bank's opening charge of USD 500 to USD 1,000 (market guide, September 2026).

The trustee provides a clear, documented chain of title recognized by the registry, and the trust deed itself becomes the primary estate document for that asset, independent of home-country wills or probate courts. For anyone exploring homes and condos for sale in Cozumel, understanding the fideicomiso is not optional—it is the legal foundation of ownership, and the quality of the succession clause you negotiate at closing will determine your heirs' experience years later.

Fideicomiso Beneficiaries: The Most Important Estate-Planning Clause

The substitute-beneficiary clause in a fideicomiso trust deed determines whether the property transfers smoothly to heirs or enters a prolonged, expensive probate proceeding under Quintana Roo law, because it names the individuals who automatically assume the beneficial interest upon the death of the primary beneficiary.

Every fideicomiso names a first or primary beneficiary—the buyer—who holds all beneficial rights during their lifetime. The trust deed should also name one or more substitute beneficiaries, individuals (or in some cases, entities) who automatically assume the beneficial interest upon the death of the primary beneficiary. This clause is not filled in by default; the buyer must affirmatively designate heirs, provide their full legal names and nationality, and confirm that instruction in the trust document signed at closing.

If the primary beneficiary dies without having named a substitute, the beneficial interest becomes part of the estate and must be distributed through formal succession proceedings—either testate (if a Mexican will exists) or intestate (following the default heir hierarchy in Quintana Roo's civil code). In that scenario, the fideicomiso remains in place and the trustee continues to hold legal title, but the beneficial rights are frozen until a court or notary declares the lawful heirs and instructs the bank to amend the trust accordingly. That process can take six months to two years, involves notary fees, legal representation, translation, apostille, registry searches, publication, and in some cases, family court hearings.

When I review a fideicomiso for a buyer, the first thing I check is whether the substitute-beneficiary section is complete, current, and reflects the client's actual wishes. I have seen cases where the named substitute is an ex-spouse from a prior marriage, a sibling who predeceased the owner, or a parent who is no longer living—each creating confusion, delay, and legal expense for the surviving family.

The substitute beneficiary may be any individual who is legally eligible under SRE rules to hold a beneficial interest in the restricted zone. Mexican nationals, permanent residents, and temporary residents all qualify; foreign nationals without Mexican residency also qualify, subject to the same fideicomiso requirement. In practice, US and Canadian citizens commonly name their children, spouses, or trusts as substitute beneficiaries, and banks will accept those designations as long as the named party is clearly identified.

Some trust deeds allow the primary beneficiary to designate percentages—for example, 50% to a spouse and 25% each to two children—while others require a single substitute or a sequential list (first to the spouse, then to children if the spouse does not survive). The flexibility depends on the bank's standard template and the specific language negotiated at the time of purchase or amendment. It is worth asking the trustee and the closing notary whether proportional or contingent beneficiaries are permitted, because that can simplify family planning and avoid the need for a Mexican will to allocate shares.

The fideicomiso can be amended at any time during the primary beneficiary's life by executing an amendment before the notary and filing it with the trustee. The cost is typically a notary fee of a few hundred to a few thousand US dollars, depending on the complexity and the bank's administrative charge. Keeping the substitute-beneficiary clause current—after marriage, divorce, the birth of children, or the death of a named heir—is essential preventive planning.

Importantly, naming a substitute beneficiary in the fideicomiso does not eliminate the need for a Mexican will if you own other assets in Mexico (such as a car, a second property held directly, or a membership interest in a Mexican corporation). The fideicomiso clause governs only that specific trust-held property. A comprehensive estate plan for a foreign Cozumel owner typically includes both an updated fideicomiso and a separate Mexican will covering any assets outside the trust.

What if a substitute beneficiary dies first?

If a named substitute beneficiary predeceases the primary beneficiary, the trust deed may provide for a secondary or contingent beneficiary, or the primary beneficiary may amend the trust to name a new substitute; if neither option is available and the owner dies, the beneficial interest enters the estate and requires probate to determine heirs under the will or Quintana Roo's intestate succession hierarchy.

What if an heir refuses?

If a substitute beneficiary refuses the inheritance, Quintana Roo civil-code provisions governing renunciation apply, and the beneficiary must formally decline in writing before a notary; the beneficial interest then passes to any contingent beneficiary named in the trust deed or, if none, enters the estate for distribution to the next lawful heirs under the will or intestate rules, requiring notarial or judicial proceedings.

Can a minor, entity, charity, or foreign trust be named?

A minor can be named as a substitute beneficiary, but a legal guardian or parent must act on the minor's behalf until the age of majority (18 years). Whether an entity (such as a corporation or LLC), a charity, or a foreign trust may be designated depends on the trustee bank's policy and the trust deed's language; some banks permit these designations subject to additional documentation and approval, while others limit substitute beneficiaries to natural persons, so the buyer should confirm the bank's practice before attempting to name a non-individual heir.

What if heirs disagree?

If multiple heirs are named and disagree on property management, sale, or distribution, the trust deed may provide dispute-resolution procedures; if it does not, the heirs may need to petition a Quintana Roo court for partition, sale, or appointment of a neutral administrator, a process that can take months or years and involve legal fees, so clear proportional or sequential beneficiary designations and a Mexican will reduce conflict.

Fideicomiso Succession Step by Step

1. Notify the trustee: The substitute beneficiary or estate executor contacts the trustee bank's fiduciary department and requests succession or substitution of beneficiary, providing the decedent's name, trust number, and date of death.
2. Obtain and apostille the death certificate: Request a certified death certificate from the vital-records office in the jurisdiction where death occurred. If issued abroad, obtain an apostille from the designated authority (Secretary of State in a US state, or Global Affairs Canada) and arrange an official Spanish translation by a certified translator (perito traductor) in Mexico.
3. Gather identity and eligibility documents: The substitute beneficiary provides a valid passport, proof of Mexican residency (if applicable), a foreign tax identification number (for FATCA and CRS reporting), and evidence of the family relationship or acceptance of the beneficial interest. If the substitute is a minor, include a legal guardian's identification and acceptance.
4. Complete trustee forms: Fill out the bank's succession or substitution request forms, updated KYC questionnaires, and beneficial-ownership declarations, signing where required.
5. Execute the amendment before a notary: The trustee, the substitute beneficiary (or legal representative), and a notary sign an amendment to the fideicomiso contract, replacing the primary beneficiary with the substitute. The notary verifies identities, confirms legal capacity, and ensures compliance with the original trust deed and SRE regulations. Notary fee: typically USD 500 to USD 2,000 (market guide, September 2026).
6. Register the amendment: The signed amendment is filed in the Public Registry of Property (Registro Público de la Propiedad) in Cozumel, updating the public record to reflect the new beneficiary. Registry fee: approximately 0.5% to 1.0% of declared value, though succession amendments may qualify for a reduced rate (closing-costs guide, September 2026).
7. Update bank records and accounts: The bank updates its fiduciary records, customer due-diligence files, and beneficial-ownership registers, and the substitute beneficiary receives confirmation and account access. The property remains in the fideicomiso, and rights to use, rent, or sell continue uninterrupted.

Throughout this process, the property itself remains in the fideicomiso, the bank remains the legal title holder, and the rights to use, rent, or sell the property continue uninterrupted once the substitution is complete. There is no change in the physical asset, the tax parcel number, or the predial account; those are tied to the trust, not to the individual beneficiary. Total timeline: three to twelve months, depending on document processing, notary availability, and registry backlog.

From a practical standpoint, I recommend that every fideicomiso owner keep a file with a copy of the trust deed, a list of named beneficiaries, contact information for the trustee bank, and clear instructions for the executor or family. That simple step can save heirs months of confusion and thousands of dollars in duplicated searches and legal fees.

Does a US or Canadian Will Work in Mexico?

A US or Canadian will does not automatically transfer Mexican real estate; while it may express the testator's intent and be recognized by a Mexican court or notary after apostille and translation, the transfer still requires a formal Mexican succession proceeding, whereas a separate Mexican will executed before a notary avoids that delay and is recommended for every foreign owner.

Many foreign buyers assume their home-country estate plan covers all their worldwide assets, but real property is governed by the law of the place where it sits—a principle called lex rei sitae. For a condo in Cozumel, Quintana Roo law determines the succession procedure, even if the owner was a US or Canadian citizen who died in North America with a valid will drafted by a licensed attorney.

A US or Canadian will can be enforced in Mexico, but the process involves several steps. First, the original will (or a certified copy) must be apostilled in the state or province where it was executed. Second, it must be translated into Spanish by a certified translator recognized in Mexico. Third, the executor or heirs present the apostilled, translated will to a notary or a civil court in Quintana Roo and request a declaration of heirs and transfer of the property. The notary or judge reviews the will, verifies it meets formal requirements, confirms no conflicting Mexican will exists, and issues a resolution or act of succession. Finally, that resolution is registered in the Public Registry of Property to update title or, in the case of a fideicomiso, to instruct the trustee bank to amend the beneficiary. This process is not automatic, can take six to eighteen months, and involves notary fees, legal representation, translation, apostille, and registry charges—often totaling several thousand US dollars.

A Mexican will, by contrast, is executed in Spanish before a Mexican notary, is already in the local legal format, and can be probated or used to instruct a trustee in a matter of weeks or months with fewer procedural hurdles. The good news is that a Mexican will can coexist with a US or Canadian will without conflict, as long as each document clearly states its scope. A typical structure is a US or Canadian will that disposes of all assets except Mexican real property, combined with a Mexican will that disposes only of the testator's Mexican assets. Each document includes a savings clause confirming it does not revoke the other.

For fideicomiso property, a Mexican will serves a secondary but still valuable role: it can clarify the testator's intent regarding the beneficial interest, name an executor familiar with Mexican law, and cover any personal property, vehicles, or secondary assets in Mexico that are not held in the trust. Even where a substitute beneficiary is named in the fideicomiso, a will provides a backup and simplifies estate administration.

The cost of a Mexican will is modest. A straightforward will drafted and executed before a notary in Quintana Roo typically costs between USD 200 and USD 800 (market guide, September 2026). The testator appears in person, presents identification (passport and, if available, Mexican residency card), describes the assets and the intended disposition, and signs the document in the presence of the notary and witnesses. The notary retains the original in a secure registry, provides a certified copy to the testator, and files a notice with the National Registry of Wills (Registro Nacional de Avisos de Testamento), ensuring the will can be located after death.

I encourage every foreign buyer to execute a Mexican will within a few months of closing. The window when you are already in Cozumel, working with a notary and a local adviser, is the easiest time to complete this planning; waiting until "someday" often means it never gets done, and the heirs pay the price in time, stress, and legal fees.

What Do Property Inheritance Laws in Cozumel Require?

Property inheritance laws in Cozumel require that fideicomiso succession follow the substitute-beneficiary clause in the trust deed or, if none exists, formal probate under Quintana Roo's civil code; that direct-title property pass by Mexican will or intestate succession; that heirs present apostilled death certificates, identity documents, and translations; that any applicable ISAI acquisition tax and future capital-gains tax obligations be satisfied; and that predial, trustee fees, and other property costs remain current throughout the succession process.

When a foreign owner of Cozumel property dies with a valid Mexican will, the estate is settled through a notarial or judicial probate proceeding that verifies the will, declares the heirs, pays any debts and taxes, and transfers title or instructs the trustee, while a death without a will triggers intestate succession under Quintana Roo's civil code, which follows a statutory heir hierarchy prioritizing descendants, then ascendants and spouses, and finally collateral relatives.

Mexican law recognizes several types of wills. The most common is the testamento público abierto (open public will), executed before a notary with witnesses, which is the standard estate-planning instrument for foreign owners. After death, any person with knowledge of a will's existence—typically the executor or an heir—locates the original or a certified copy and initiates probate. In many cases in Quintana Roo, probate can be handled administratively before a notary rather than in court, a faster and less expensive process called sucesión testamentaria extrajudicial. The notary verifies the will's validity, confirms no challenges or disputes exist among heirs, settles creditor claims, calculates and pays any applicable taxes, and issues a notarial act (escritura de adjudicación) transferring the assets to the named beneficiaries. That act is then registered in the Public Registry of Property. The timeline for notarial probate is typically three to six months.

If the will is contested, if heirs disagree, or if creditors file claims that cannot be resolved administratively, the matter moves to a civil court for judicial probate (juicio sucesorio testamentario), which can take one to three years and involves attorney fees, court costs, publication, hearings, and formal proof of claims.

When no will exists, the estate is distributed through intestate succession (sucesión legítima or sucesión intestamentaria). Quintana Roo's civil code (see Congreso del Estado de Quintana Roo for the current Código Civil para el Estado de Quintana Roo) sets out a clear heir hierarchy. First in line are descendants (children, grandchildren, great-grandchildren), who inherit in equal shares per stirpes. If no descendants survive, the estate passes to ascendants (parents, grandparents) and the surviving spouse or recognized domestic partner in proportions set by statute. If neither descendants nor ascendants exist, collateral relatives (siblings, nieces, nephews, aunts, uncles, cousins up to the fourth degree) inherit. If no family can be identified, the property ultimately escheats to the state of Quintana Roo.

Mexico does not impose strict forced heirship in the same way as some European or Latin American jurisdictions, but the civil codes do protect the rights of descendants, ascendants, and spouses to claim support from the estate (alimentos) if they can demonstrate need. In practice, a testator has broad freedom to dispose of property by will, but cannot entirely disinherit a spouse or minor children without risking a successful challenge.

Surviving spouses and registered domestic partners have specific rights that vary by state. In Quintana Roo, a spouse generally inherits a portion of the estate even in intestacy, and a formal domestic partnership (concubinato) recognized under state law can also give rise to inheritance rights. Common-law relationships not formally registered may be harder to prove and enforce, requiring evidence of cohabitation, financial interdependence, and intent to establish a permanent union. A licensed Mexican notary or tax adviser should assess the couple's circumstances.

Intestate probate, like testate probate, may proceed before a notary if heirs agree and no disputes arise, or in court if conflict or complexity demands judicial oversight. Either way, the process requires proof of death, proof of family relationship (birth certificates, marriage certificates, all apostilled and translated if issued abroad), a declaration of heirs, settlement of debts and taxes, and a final distribution order or notarial act. The cost and duration are typically higher than for a testate estate.

Incapacity, Divorce, Blended Families, Unequal Distributions, Minor Heirs, and Refusal

Incapacity: If a substitute beneficiary or heir is declared legally incapacitated, a court-appointed guardian or conservator must act on that person's behalf, and the notary or court will require proof of the guardianship order (apostilled and translated if foreign) before transferring the beneficial interest or title.

Divorce and blended families: A divorced spouse is not an intestate heir in Quintana Roo unless specifically named in a will or trust deed. Blended families with children from prior marriages should use a Mexican will or detailed beneficiary designations to specify which children inherit, in what proportions, and whether stepchildren or former spouses receive anything. Without clear instructions, the civil code's default rules may produce unintended results.

Unequal distributions: A testator may distribute property unequally among heirs by will, subject to the alimentos claims noted above. The fideicomiso trust deed may also specify unequal percentages if the bank's template permits. Where percentages are not permitted, a Mexican will can direct the disposition of other assets to balance the inheritance.

Minor heirs: A minor (under 18 years) can inherit but cannot sign legal documents or manage property. A parent or court-appointed guardian must act as legal representative, and the notary will verify the guardian's authority. Some trust deeds allow the primary beneficiary to name a custodian or trustee to manage the minor's share until majority.

Refusal: An heir or substitute beneficiary may refuse (renounce) an inheritance by executing a formal renunciation before a notary within a statutory period (typically a few months after learning of the inheritance). The renunciation is irrevocable, and the share passes to contingent heirs named in the will or trust deed, or to the next class of intestate heirs if none are named.

Inheritance Tax, ISAI, and Future Capital Gains

Mexico imposes no federal inheritance tax or estate tax, but heirs of Cozumel property may face a local real-estate acquisition tax (ISAI), income-tax obligations if they are Mexican tax residents, and future capital-gains tax when they sell, while foreign tax residents may also trigger withholding or home-country estate-tax and reporting rules.

At the federal level, the Ley del Impuesto sobre la Renta (ISR, or Income Tax Law) generally exempts inheritance receipts from income tax for qualifying individuals. The key distinction is between Mexican tax residents and foreign tax residents. An individual is considered a Mexican tax resident if they have established their home in Mexico (casa habitación) or if their center of vital interests is in Mexico. A foreigner who spends most of the year in the United States or Canada and does not hold permanent residency is typically a foreign tax resident. A foreigner who has moved to Mexico, obtained permanent residency, and made Cozumel their primary home is a Mexican tax resident for income-tax purposes.

For a Mexican tax resident heir receiving property by inheritance, the transfer is generally exempt from federal income tax, though any income generated by the property (rent, for example) after the date of death becomes taxable to the heir. For a foreign tax resident heir, the treatment is less clear, and some tax advisers read the law to impose a potential withholding or deemed-income calculation on the transfer, particularly where the property is sold shortly after inheritance. A licensed Mexican notary or tax adviser should assess the specific situation before assuming exemption.

ISAI in Quintana Roo (Reviewed for 2026): ISAI (Impuesto Sobre Adquisición de Inmuebles) is a state or municipal acquisition tax levied on real-property transfers. In Quintana Roo, ISAI is governed by the Código Fiscal del Estado de Quintana Roo and the Ley de Hacienda del Estado (see Congreso del Estado de Quintana Roo for current fiscal-code provisions). National guides report a range of approximately 1 percent to 6 percent of property value, depending on jurisdiction and calculation method. The exact rate, exemptions, and treatment of inheritance transfers in Quintana Roo should be confirmed with the state finance ministry (Secretaría de Finanzas y Planeación, SEFIPLAN) or a Quintana Roo notary before closing any estate, because rates and rules change periodically with state budgets and tax reform. Some jurisdictions exempt or reduce ISAI for transfers to direct descendants or surviving spouses; others do not. Without an official, current statement from SEFIPLAN, the precise Quintana Roo ISAI treatment of inheritance must be verified locally.

Regardless of ISAI, the heir must obtain an official appraisal (avalúo) of the property to establish the taxable base. The appraiser is typically a certified professional (perito valuador) approved by the local finance authority, and the cost ranges from USD 200 to USD 800 (market guide, September 2026). The appraisal is submitted with the succession paperwork and used to calculate any acquisition tax due, update the property's cadastral value for predial purposes, and establish the heir's tax basis for future capital-gains calculations.

The question of tax basis—what the heir is deemed to have "paid" for the property when calculating gain on a later sale—is disputed in Mexican practice. Some advisers assert that inherited property receives a stepped-up basis equal to the fair market value at the date of death, while others argue that the heir inherits the decedent's original acquisition cost and adjusted basis. The difference can be tens of thousands of dollars in tax. Until Mexican tax law or a clear SAT regulation settles this question uniformly, every heir should obtain written tax advice from a Mexican accountant before selling, preserve all appraisals and succession documents, and be prepared to document either the original basis or the appraised value, whichever SAT accepts.

When the heir eventually sells the Cozumel property, capital-gains tax applies. For a Mexican tax resident individual, the gain is calculated as the sale price minus the acquisition cost (or stepped-up basis, if recognized), minus allowable deductions (improvements, notary fees, commissions), minus an inflation adjustment, with the net gain added to annual income and taxed at progressive rates up to 35 percent. For a foreign tax resident, the notary is required to withhold tax at the time of sale: either 25 percent of the gross sale price, or, if the seller appoints a Mexican legal representative and the sale is properly documented, 35 percent of the net capital gain.

Predial, the annual property tax, continues regardless of inheritance. In Quintana Roo, predial is assessed by the municipality based on the property's cadastral value and paid to the municipal treasury. Predial is estimated at approximately 0.05 percent to 0.3 percent of assessed value annually (market guide, September 2026). The heir becomes responsible for predial from the date of death (or the date the succession is finalized, depending on local practice), and any arrears must be settled before the registry will record the transfer or amendment. Condominium fees, utilities, insurance, and trustee annual charges also continue and must be kept current.

If the property generates rental income, that income is subject to Mexican ISR from the date of death, either as estate income (taxed to the estate or executor until distribution) or as the heir's income (once the succession is complete). A separate topic, covered in the guide to tax deductions for Cozumel landlords, explains the deductions, withholding, and reporting obligations for rental property.

Home-Country Estate-Tax and Reporting

United States: The estate of a US citizen or resident is subject to federal estate tax if the worldwide gross estate exceeds the exemption threshold (USD 13.61 million per individual in 2024, subject to adjustment). A Cozumel condo owned in a fideicomiso is included in the US gross estate at its fair market value as of the date of death. The estate-tax return (Form 706) must list the property, and estate tax is calculated on the entire estate, though a foreign tax credit may be available for any Mexican taxes paid. Heirs receiving the property may also need to report the inheritance on their own US tax returns, though inherited property is generally not income to the beneficiary under US law.

Canada: Canada has no estate or inheritance tax, but the deceased is deemed to have disposed of all capital property at fair market value immediately before death, triggering a capital-gains tax on the final return (T1). The Cozumel property is valued at fair market value, the gain is calculated from the original acquisition cost (adjusted for improvements and exchange-rate changes), and the Canadian estate pays tax on the gain. The heir receives the property with a new adjusted cost base equal to the deemed disposition value, meaning no further Canadian gain on the same appreciation. However, any Mexican taxes paid may generate a foreign tax credit on the Canadian return, avoiding double taxation.

Coordination between Mexican and home-country tax advisers is essential to avoid duplicate reporting, missed credits, and compliance penalties.

What Should a Cozumel Heir Budget for in 2026?

A Cozumel heir should budget for trustee substitution fees, notary charges, registry updates, official appraisal, apostille and translation, legal advice, and property-management costs, plus annual trustee fees during succession and any applicable ISAI, with total expenses typically ranging from several thousand to over ten thousand US dollars depending on property value and complexity.

Cozumel Rental Licensing, Condominium Rules, Tourism Registration, and Occupancy Obligations

If the inherited property was being used as a short-term vacation rental, the heir must comply with Cozumel's municipal licensing, state tourism registration, and tax obligations. A municipal short-term rental license (licencia de uso de suelo for tourist lodging) is required, along with registration with the Quintana Roo tourism secretariat (SEDETUR). The municipal lodging tax (Impuesto Sobre Hospedaje, ISH) of 3 percent of the nightly rate must be collected and remitted monthly. Condominium bylaws may restrict or prohibit short-term rentals, and the heir should review the HOA rules and obtain written confirmation that rentals are permitted before listing the property. Failure to comply with licensing, tax, or HOA rules can result in fines, suspension of rental platforms, or legal action by the HOA.

Vacant-Property Compliance Checklist During Estate Administration

• Confirm fideicomiso annual fee is current and arrange automatic payment if possible.
• Pay predial and request a certificate of no-debt (certificado de no adeudo) from the municipality.
• Settle all condominium fees and obtain an HOA clearance letter.
• Transfer or continue utility accounts (electricity, water, internet, gas) to prevent disconnection.
• Review and maintain property, liability, and windstorm insurance; notify the insurer of the death and request continuation.
• If the property is rented, continue ISR and lodging-tax filings and remittances.
• Inspect the property monthly or arrange for a local property manager to check for maintenance issues, storm damage, leaks, pest control, and security.
• Notify the trustee bank, the property manager, and the HOA of the death and provide interim contact information.
• Maintain a shared digital folder with copies of the trust deed, succession documents, receipts, insurance policies, and contact information for the trustee, notary, accountant, and attorney.

Residency, Reporting, and Home-Country Tax Coordination

Owning or inheriting Cozumel property does not automatically grant Mexican residency or create an immigration benefit, but US and Canadian heirs must report foreign assets and income to their home-country tax authorities, coordinate estate-tax filings, and in some cases, disclose offshore accounts under FATCA and the Common Reporting Standard to avoid penalties.

Mexican immigration law distinguishes among tourist visitors (no visa required for stays up to 180 days under the FMM tourist permit), temporary residents (residente temporal), and permanent residents (residente permanente). Residency status is based on visa eligibility criteria—such as family ties, employment, retirement income, or investment—and is granted by Mexico's National Immigration Institute (Instituto Nacional de Migración, INM). Simply owning property in Cozumel, whether through a fideicomiso, direct title, or a corporation, does not qualify the owner for temporary or permanent residency.

For inheritance purposes, the substitute beneficiary's residency status matters for Mexican tax treatment, but does not affect the legal right to inherit. A foreign national without any Mexican visa or residency can inherit a Cozumel fideicomiso, step into the beneficiary role, pay the trustee fee, collect rent, and eventually sell—all without obtaining residency, as long as they comply with tax and reporting rules.

United States: US tax residents and citizens must report worldwide income to the Internal Revenue Service, including rental income from Mexican property. Rental income is reported on Schedule E of Form 1040, with expenses deductible against income. US persons with a financial interest in, or signature authority over, foreign financial accounts exceeding USD 10,000 in aggregate value at any time during the year must file a Report of Foreign Bank and Financial Accounts (FBAR, FinCEN Form 114) by April 15 (with an automatic extension to October 15). US persons with specified foreign financial assets exceeding USD 50,000 (or higher thresholds for certain filers) must also file IRS Form 8938, Statement of Specified Foreign Financial Assets, with their annual income-tax return. Under the Foreign Account Tax Compliance Act (FATCA), Mexican banks report account information for US persons to the US Treasury via an intergovernmental agreement.

Canada: Canadian tax residents report worldwide income, including Mexican rental income, on the T1 return, with foreign rental income detailed on Form T776 and foreign tax paid generating a credit on Form T2209 or a deduction. Canadian taxpayers with foreign property costing more than CAD 100,000 must file Form T1135, Foreign Income Verification Statement, disclosing the property's location, cost, and income. Failure to file T1135 carries penalties of CAD 25 per day, up to CAD 2,500 per year. Under the Common Reporting Standard (CRS), Mexican banks report account information for Canadian (and other foreign) tax residents to the Mexican tax authority, which exchanges the data with the Canada Revenue Agency.

When a US or Canadian citizen dies owning Cozumel property, the executor must file a final income-tax return in the home country reporting income through the date of death, and may need to file an estate-tax return (US Form 706) or a deemed-disposition return (Canada). The estate itself may need to obtain a tax identification number and file annual fiduciary income-tax returns if the estate remains open and generates income for more than a few months.

Coordinating these filings requires professional help. Any foreign heir of Cozumel property should engage both a Mexican accountant (for ISR, ISAI, predial, rental-income filings, and succession-tax advice) and a cross-border tax adviser in the home country (for estate-tax, FBAR, Form 8938, T1135, foreign tax credits, and dual-resident issues).

Our Recommendation

Every foreign owner of Cozumel property should name substitute beneficiaries in the fideicomiso trust deed at the time of purchase or by amendment within the first year, execute a Mexican will before a Quintana Roo notary to cover any assets outside the trust and clarify testamentary intent, and review both documents after marriage, divorce, the birth or death of a family member, or any change in financial or residency status. The combined cost is modest—typically under USD 2,000 for both the will and a beneficiary amendment—and the protection is comprehensive.

If you already own property and have never named a substitute beneficiary or executed a Mexican will, make that your priority for the next trip to Cozumel. Contact your trustee bank, your notary, or a local adviser, bring your passport and proof of property ownership, and complete the planning in a single appointment.

For buyers just starting the search, incorporate estate planning into the purchase timeline. Review the substitute-beneficiary clause in the draft fideicomiso before closing, confirm the language is clear and reflects your intent, and ask the notary whether proportional or contingent beneficiaries are permitted. Budget for a Mexican will as part of closing costs, not as a "someday" task.

If your estate includes multiple properties, significant rental income, or complex family structures—blended families, minor children, special-needs dependents, cross-border trusts—engage both a Mexican tax attorney and a US or Canadian estate-planning attorney to design a coordinated plan. The interaction of Mexican succession law, ISR, ISAI, US estate tax, Canadian deemed-disposition rules, FBAR, FATCA, and CRS reporting is too intricate for a general guide; you need personalized advice in writing, signed by licensed professionals in both countries.

Next step: Request the current trust deed from the trustee and have a Quintana Roo notary review its beneficiary clause. Update or add substitute beneficiaries if needed, and execute a Mexican will during the same appointment. Keep copies of both documents in a secure digital folder shared with your executor and family, along with contact information for the trustee, notary, accountant, property manager, and home-country estate attorney.
