Legal Aspects in the Acquisition of Real Estate Through Auctions

April 13, 2026 — Enrique Benet-Gregg

Taxonomy of Real Estate Auctions Under Mexican Law

Acquiring real estate through a judicial or administrative auction in Mexico presents a fundamentally different risk profile from any conventional purchase. The buyer in a remate does not negotiate with a willing seller capable of providing representations and warranties; the acquisition occurs within a coercive procedural framework where title defects, surviving encumbrances, and nullity risks must be identified and mitigated before the bid is submitted, not after. Understanding the precise legal regime governing each type of auction is the necessary starting point for any investor operating in this space.

Mexican law recognizes four principal auction regimes applicable to real property, each governed by distinct procedural rules and generating different consequences for the acquiring party:

Judicial civil auction (remate judicial civil): arising from enforcement of a civil judgment or mortgage foreclosure under state codes of civil procedure. In Quintana Roo, this is governed by the Code of Civil Procedures of the State of Quintana Roo.
Judicial commercial auction (remate judicial mercantil): conducted within an executive commercial proceeding (juicio ejecutivo mercantil) under Articles 1391 to 1414 of the Commercial Code, which refers auction mechanics to the applicable state procedural code by virtue of Article 1414.
Administrative fiscal auction (remate administrativo fiscal): executed through the administrative enforcement procedure (procedimiento administrativo de ejecución) (PAE) of the Tax Administration Service (Servicio de Administración Tributaria - SAT) or other federal enforcement authorities, regulated by Articles 145 to 196 of the Federal Tax Code (CFF).
Concurrent auction (subasta concursal): the sale of real property assets within insolvency proceedings governed by the Bankruptcy Law (Ley de Concursos Mercantiles) (LCM), under the supervision of the Federal Institute of Commercial Bankruptcy Specialists (Instituto Federal de Especialistas de Concursos Mercantiles) (IFECOM).

A fifth category — the voluntary or extrajudicial public auction — operates outside coercive proceedings but remains subject to notarial formalities, public property registry registration requirements, and, depending on the parties involved, to supervision under the Credit Institutions Law when banks liquidate non-performing mortgage portfolios.

The Judicial Auction Process: Structure and Critical Junctures

Appraisal and Minimum Bid

Before any judicial auction of real property proceeds, the seized asset must be appraised by a certified valuator. The appraisal generates the base value from which the legal bid (postura legal) — the minimum legally admissible bid — is derived. Under the procedural framework applicable in Quintana Roo and under the Federal Code of Civil Procedures (CFPC), the legal bid (postura legal) is set at two-thirds of the appraised value in the first call. If the first call produces no qualified bidders, successive calls may reduce this floor, though the rules governing successive reductions vary by state code and by whether the proceeding is civil or commercial in nature.

Bidders must post a deposit or bond — typically ten percent of their proposed postura — as a condition of participation. Failure to complete payment after winning the auction results in forfeiture of this deposit and, in some jurisdictions, disqualification from future auction proceedings in the same case.

Notification, Publication, and Bidding

Publication of the auction notice (convocatoria) through public notices (edictos) in official and commercial media is a substantive procedural requirement, not merely formal. The First Chamber of the SCJN and multiple Circuit Collegiate Courts have consistently held that failure to comply with mandatory publication requirements — including the minimum intervals between publication and the auction date — constitutes a procedural defect sufficient to nullify the auction proceeding, even where a third party in good faith has already taken possession.

With respect to the specific judicial authority underlying this doctrine, a precise citation requires clarification of an important limitation: the individual theses and jurisprudences of the Federal Judicial Gazette addressing public notices (edictos) nullity in auction proceedings are numerous and span multiple circuit courts and epochs, and identifying a single authoritative registration number applicable across all procedural variants exceeds what responsible citation practice allows without access to the current IUS/SJFG database at the time of publication. Practitioners and litigants should conduct a targeted thematic search in the Federal Judicial Gazette and its Official Gazette under the rubric “AUCTION — NULLITY — PUBLIC NOTICES” and “SALE — PUBLICATION REQUIREMENTS,” filtering by First Chamber and by the relevant Circuit Collegiate Courts, to identify the applicable thesis for the specific procedural code at issue. This judicial criterion — whatever the precise registration number — makes pre-acquisition verification of the complete procedural file an indispensable due diligence step, not an optional precaution.

Adjudication and Title Transfer

Upon conclusion of bidding, the presiding judge issues an auto de adjudicación — a judicial pronouncement that operates as the equivalent of a deed of sale in favor of the winning bidder. The transfer, however, is not complete for third-party purposes until the auto de adjudicación is formalized before a Notario Público and recorded in the Registro Público de la Propiedad (RPP). Article 3042 of the Código Civil Federal — and its equivalent in the Código Civil del Estado de Quintana Roo — establishes that real property transfers are only enforceable against third parties from the date of registration. The gap between judicial adjudication and RPP inscription is a period of latent vulnerability that sophisticated buyers must address by expediting formalization.

Title Risk and Encumbrance Survival: The Core Buyer’s Dilemma

The most significant structural risk in Mexican real estate auctions is the non-automatic extinguishment of pre-existing encumbrances. Unlike the Spanish system (discussed below), Mexican judicial auctions in civil and commercial proceedings do not, as a default rule, release the acquired property from all prior encumbrances. Specifically:

Preferential mortgages registered before the lien underlying the auction proceeding remain attached to the property unless the executing creditor held a first-ranking mortgage or unless those creditors were specifically joined in the proceeding. The SCJN has addressed this in cases involving competing mortgage creditors, consistently protecting earlier-registered rights under the principio de prelación registral. The specific tesis sustaining this doctrine should be verified by practitioners through a Semanario Judicial de la Federación search under the rubric “REMATE — HIPOTECA PREFERENTE — PRELACIÓN REGISTRAL”; the doctrine has been affirmed in multiple tesis aisladas by Tribunales Colegiados de Circuito in civil matters, though a single governing jurisprudencia binding on all circuits has not been definitively consolidated as of the date of this publication, and this limitation is expressly acknowledged.
Usufructs and surface rights registered at the RPP prior to the embargo may survive adjudication, particularly where the right-holder was not properly notified of the proceedings.
Third-party possessory rights — including informal occupation and residential tenancies protected by state housing legislation — are not extinguished by the auction and must be resolved separately, often through eviction proceedings that can be protracted in tourist corridor municipalities.
Federal environmental and administrative limitations on coastal and protected zone properties in Quintana Roo — including Zona Federal Marítimo Terrestre concessions, ANP buffer zones, and SEMARNAT restrictions — are not affected by the judicial auction and bind the acquiring party from the moment of adjudication.

Eduardo Pallares, in his foundational Diccionario de Derecho Procesal Civil Mexicano, characterized the judicial auction as a compraventa forzosa — a forced sale — that produces the legal effects of an ordinary purchase but without the seller’s active cooperation in clearing title. This characterization has been affirmed by the Primera Sala of the SCJN. Practitioners should note, however, that the authors have been unable to confirm a single definitive tesis registro number for this characterization that applies uniformly across civil, mercantil, and fiscal auction variants; the doctrine has developed through multiple tesis aisladas across different epochs of the Semanario Judicial de la Federación, and litigants should verify the applicable precedent by searching under the rubric “REMATE — COMPRAVENTA FORZOSA — EFECTOS” in the current IUS database. The practical implication is nonetheless clear: the buyer assumes responsibility for investigating all defects the seller would have been obligated to disclose in a voluntary transaction.

Administrative and Tax-Driven Auctions Under the CFF

When the SAT seizes and auctions real property through the PAE, the procedural framework under Articles 145 to 196 of the CFF differs substantially from judicial civil auctions. The postura legal in a fiscal PAE auction is governed by a dual-floor mechanism under Article 176 of the CFF that buyers must understand precisely, because the acquisition opportunity it creates is conditional, not universal.

Under Article 176 of the CFF, the minimum admissible bid at the first call is the higher of two values: (a) the total amount of the tax credit being collected — encompassing principal (omitted contribution), surcharges (surcharges), penalties (fines), and costs of execution (execution costs); or (b) two-thirds of the appraised value of the property. Where the tax credit substantially exceeds the appraised value, the floor is effectively the tax credit and buyers bid against that figure, which may not represent a discount relative to market. The acquisition opportunity at a significant discount arises specifically — and only — in the scenario where the appraised value substantially exceeds the outstanding tax credit, causing the two-thirds-of-appraisal floor to govern and the tax credit to represent a relatively modest fraction of property value. Buyers who assume that PAE auctions systematically produce below-market acquisitions will encounter scenarios where this expectation does not materialize. For successive calls following an unaccepted first call, Articles 177 and 178 of the CFF establish the rules governing reduction of the legal bid, which practitioners must consult for the specific applicable sequence.

SAT conducts real property auctions through its electronic platform (online auctions), which has substantially increased procedural transparency compared to earlier in-person auction processes. However, buyers must note that under Article 192 of the CFF, if no qualified bid is presented after the required calls, the SAT may adjudicate the property to itself (adjudication to the government) and subsequently dispose of it through the Service of Administration and Sale of Assets (SAE). This backstop mechanism reduces but does not eliminate the risk of contested subsequent sales from buyers who acquired from the SAE rather than directly at auction.

A critical distinction between fiscal and judicial auctions: under the CFF framework, the acquiring party at a tax auction does not obtain a guarantee against surviving encumbrances in favor of other creditors. Pre-existing mortgages registered prior to the SAT’s embargo lien retain their priority under the RPP’s real folio system, and IMSS, INFONAVIT, and other parastate credits may assert preferential claims that were not incorporated into the SAT proceeding.

Bankruptcy Auctions Under the Ley de Concursos Mercantiles

Real property auctions in concurso mercantil proceedings are structurally distinct from both judicial and tax auctions. The LCM establishes a collective insolvency framework under which recognized creditors, organized by class and priority, receive distributions from the liquidation of the debtor’s assets. The trustee appointed by IFECOM directs the liquidation process, including the sale of real property either through public auction or private sale authorized by the concurso judge.

The LCM provides a degree of encumbrance rationalization unavailable in ordinary judicial auctions: the insolvency proceeding consolidates competing creditor claims before a single court, allowing for a more orderly resolution of priority disputes. Nevertheless, buyers at concursal auctions must independently verify whether the property was subject to a mortgage perfected before the debtor’s insolvency, as secured creditors may exercise their rights separately (creditors with real guarantee) and are not automatically bound to accept the concursal proceeding’s terms. Rafael Rojina Villegas, in his Compendium of Civil Law, Volume IV, notes that the real guarantee (real guarantee) follows the asset, not the person of the debtor — a principle that survives insolvency proceedings.

Comparative Framework: Spain and the United States

Spain: LEC and Mandatory Encumbrance Disclosure

Spain’s Civil Procedure Act (LEC), specifically Articles 655 to 698, governs judicial auctions of real property and incorporates a mechanism absent from Mexican law: the certificate of encumbrances issued by the Property Registry is mandatory before the auction can proceed and must be disclosed to all bidders. This certificate identifies all registered encumbrances, distinguishes between those that will be extinguished upon adjudication (those inferior in rank to the executing creditor’s lien) and those that will survive (superior-ranking encumbrances that the buyer must absorb). Since 2015, Spain’s auctions are conducted through the centralized portal subastas.boe.es, with mandatory minimum bidder deposits and real-time transparency.

The structural contrast with Mexico is significant: Mexico has no equivalent to the mandatory pre-auction certificate of encumbrances with binding legal force on encumbrance survival. The prospective buyer at a Mexican auction must independently commission a full RPP title study (title study) because no procedural mechanism compels the court to produce a binding encumbrance map before bidding opens. This is perhaps the most consequential legislative gap in the Mexican system.

United States (Florida): Foreclosure, Certificate of Title, and Title Insurance

Florida’s judicial foreclosure model under Florida Statutes §702.015 et seq. offers a second instructive comparison. Upon completion of a Florida foreclosure sale and issuance of a Certificate of Title, the acquiring party receives a title that extinguishes all junior liens and encumbrances — those recorded after the foreclosed mortgage. This seniority-based extinguishment principle provides materially greater certainty than the Mexican model. However, even in Florida, senior liens (including IRS federal tax liens, HOA super-priority claims, and first-mortgage liens if the foreclosing creditor held a junior lien) survive. Post-acquisition quiet title actions remain common.

The mature U.S. title insurance market — with providers such as First American Title and Stewart Title offering judicial auction endorsements — partially compensates for residual uncertainty. In Mexico, title insurance penetration in the auction segment remains limited despite the presence of major U.S. title insurers in the Riviera Maya market. Cipriano Gómez Lara, in his Derecho Procesal Civil, identified the absence of a developed guarantee mechanism for auction buyers as a persistent structural deficiency of the Mexican civil procedure system — an observation that remains accurate in 2026.

Anti-Money Laundering and Fiscal Obligations for Auction Buyers

The Federal Law for the Prevention and Identification of Operations with Resources of Illicit Origin (LFPIORPI) designates real estate transactions as a vulnerable activity under Article 17, fraction XI. This designation applies regardless of whether the acquisition occurs through a voluntary contract or through a judicial or administrative auction. The Notario Público formalizing the adjudication deed is required to identify the beneficial owner of the acquiring party, verify the origin of funds, and report transactions exceeding applicable thresholds to the Financial Intelligence Unit (UIF). Non-compliance may result in nullity of the formalization act and criminal liability for facilitating agents.

On the direct tax side, Article 14 of the CFF provides a broad definition of alienation that expressly includes transfers effected through court orders — meaning the buyer at a judicial auction is acquiring through a taxable transaction under the Income Tax Law (LISR). The Tax on Real Property Acquisitions (ISAI), a state and municipal tax on real property acquisitions, applies in full to auction acquisitions in Quintana Roo municipalities including Benito Juárez, Solidaridad, and Tulum.

The income tax dimension of an auction acquisition involves obligations on both sides of the transaction that directly affect the notary’s role in formalizing the adjudication deed. On the alienating party’s side, Article 126 of the LISR governs income tax withholding obligations applicable to individuals who alienate real property — a category that encompasses forced sales through judicial proceedings by virtue of Article 14 of the CFF. The notary formalizing the adjudication deed is legally required under Article 126 LISR to calculate, retain, and remit the provisional income tax payment corresponding to the gain realized by the alienating party, calculated on the difference between the adjudication price and the adjusted fiscal cost of the property. Where the alienating party is a foreign resident, Article 161 of the LISR governs, establishing different withholding rates and calculation bases applicable to non-residents alienating Mexican real property — a provision of particular operational relevance in the Riviera Maya market, where the settlor subject to enforcement proceedings is frequently a foreign national. The notary’s failure to perform these withholding calculations correctly creates personal liability for the certifying notary and may impede RPP registration of the adjudication deed. Buyers must account for these withholding obligations when modeling their net acquisition cost, as the retained amounts directly affect the net proceeds available to satisfy the underlying judgment and may influence the alienating party’s or creditor’s conduct during the formalization process.

For buyers who structure the acquisition through a legal entity, additional analysis is required under Articles 76 and 179 of the LISR regarding transfer pricing documentation and thin capitalization rules if related-party financing is involved in funding the bid. With respect to Article 18 of the LISR — which governs the moment of income accrual for moral persons — its relevance to the auction context depends on whether the acquiring entity recognizes income from the transaction, which would arise only in specific restructuring scenarios where the auction acquisition is part of a debt-to-asset exchange for an acquiring creditor-entity. For most third-party buyers at auction, Article 18 is not directly operational and its inclusion in legal analysis should be qualified accordingly.

The value-added tax treatment of auction acquisitions is a material compliance issue for institutional buyers that requires specific analysis. Under Article 9 of the Ley del Impuesto al Valor Agregado (LIVA), the alienation of land and residential buildings used exclusively for housing is exempt from IVA. However, this exemption does not apply universally to all properties acquired at auction. The transfer of commercial property, mixed-use developments, construction-phase assets, or property previously held in a business’s fixed assets through a judicial or administrative auction may trigger IVA at the applicable rate, depending on the nature of the asset and the tax status of the alienating party. Where the alienating party is an IVA taxpayer and the property does not qualify for the Article 9 exemption, the notary formalizing the adjudication deed must address IVA withholding or payment obligations in the deed itself. Institutional buyers acquiring commercial or income-producing properties at auction should obtain a specific tax opinion on IVA applicability before submitting a bid, as the IVA exposure will affect the total acquisition cost and must be factored into financial modeling. The LIVA treatment is particularly complex in PAE proceedings where the SAT is simultaneously the executing creditor and the tax authority administering IVA — a structural tension that does not have a definitive regulatory resolution applicable to all factual configurations.

Coastal Properties and the Restricted Zone

For properties located within the zona restringida — 50 kilometers from Mexico’s coastlines and 100 kilometers from its international borders, as established by Article 27, fraction I of the Constitución Política de los Estados Unidos Mexicanos — the fideicomiso inmobiliario regime under the Ley de Inversión Extranjera creates a structural complication unique to the Riviera Maya market. When a fideicomiso over coastal property is subject to judicial enforcement proceedings against the fideicomitente (typically the foreign buyer), the asset technically held by a institución fiduciaria may not be subject to embargo by the debtor’s creditors in the same manner as directly-owned property, depending on the trust’s structure and the specific rights being enforced.

Ignacio Galindo Garfias, in his treatise Derecho Civil, Primer Curso, analyzed the patrimonial separateness of trust assets under Mexican law, a principle that has been operationalized by Mexican courts to protect fideicomiso property from the personal creditors of the fideicomitente. The SCJN’s Pleno and Primera Sala have affirmed this doctrine in enforcement proceedings. As with other judicial criteria referenced in this article, practitioners should verify the precise applicable tesis registro by searching the Semanario Judicial de la Federación under “FIDEICOMISO — PATRIMONIO — SEPARACIÓN — EJECUCIÓN” and “FIDEICOMITENTE — DERECHOS FIDEICOMISARIOS — EMBARGO,” as the doctrine has developed across multiple tesis aisladas and the specific holding applicable to Riviera Maya coastal fideicomisos depends on the exact enforcement mechanism at issue.

The operational distinction that buyers pursuing auction rights over Riviera Maya fideicomiso properties must internalize is the difference between two legally distinct objects of enforcement. The derechos fideicomisarios — the beneficiary’s contractual position arising from the trust agreement, including the right to use, enjoy, and instruct disposition of the trust property — constitute personal property of the fideicomitente and can be embargoed and auctioned as part of enforcement proceedings against that individual or entity. Enforcement against the trust patrimony itself — the real property title held by the institución fiduciaria — is generally not available to personal creditors of the fideicomitente, precisely because the fiduciary institution holds legal title in a patrimony legally separated from the fideicomitente’s personal estate. This distinction is operationally critical: a buyer at auction who believes they are acquiring real property rights equivalent to direct ownership may in fact be acquiring only the fideicomitente’s contractual position, with all the limitations and contingencies that entails.

Buyers acquiring beneficiary rights at auction face a distinct regulatory sequence that has become more complex following developments in SRE administrative practice during 2023 and 2024. Under Article 11 of the Foreign Investment Law, any transfer of the beneficial position in a restricted zone trust — including a transfer effected through a judicial enforcement proceeding — requires a new permit from the Secretaría de Relaciones Exteriores (SRE), because the SRE permit is granted to a specific beneficial holder and does not automatically transfer upon adjudication. The buyer acquiring beneficiary rights at auction must therefore apply for and obtain a new SRE permit and coordinate with the fiduciary institution for formal substitution as beneficiary in the trust agreement before the acquisition is operative for practical purposes. SRE administrative processing times for restricted zone trust permits have, in recent practice, imposed timing constraints of several months that materially extend the adjudication-to-registration gap described elsewhere in this article, creating an extended window of vulnerability between the judicial adjudication of the beneficiary rights and the formal registration of the trust substitution. Buyers should budget for this administrative delay in transaction timelines and consider whether interim protective measures — including notification to the fiduciary institution of the adjudication and any available precautionary registrations — are appropriate to reduce exposure during the gap period. It should be noted that the specific regulatory developments referenced for 2023 and 2024 reflect practitioner observations regarding SRE processing practice rather than formally published regulatory amendments, and buyers should obtain current SRE guidance at the time of their specific transaction.

Legislative Gaps and Systemic Risks

A rigorous assessment of Mexico’s auction legal framework reveals several structural deficiencies that expose sophisticated buyers to avoidable risk:

Absence of mandatory pre-auction encumbrance clearance: No federal or Quintana Roo state provision requires the court to produce a binding encumbrance certificate comparable to the Spanish model. The buyer bears the full cost and risk of independent due diligence.
Fragmented procedural regimes: The coexistence of state civil procedure codes, the Commercial Code, the Federal Tax Code, and the Commercial Insolvency Law creates a patchwork system where the same property could theoretically be subject to competing auction proceedings initiated by creditors operating under different procedural frameworks. Coordination mechanisms between these regimes remain inadequate.
Delayed notarization and registration: The interval between judicial adjudication and Real Property Registry inscription — during which the buyer holds an unenforced adjudication order — creates a window of vulnerability to new encumbrances, third-party claims, and competing registrations that is not effectively addressed by any procedural provision.
Limited digital modernization: Unlike Spain’s subastas.boe.es or the SAT’s fiscal auction portal, civil and commercial judicial auctions in Quintana Roo continue to rely on physical publication and in-person bidding in most courts, limiting market access and transparency for institutional buyers.
Insufficient protection for uninformed bidders: Bernardo Pérez Fernández del Castillo, in his work on notarial practice, has observed that the notary’s role in formalizing auction adjudications is structurally limited compared to voluntary transactions — the notary cannot negotiate terms, insert protective clauses, or require encumbrance clearance as conditions of formalization.

Protecting the Auction Buyer: Available Legal Mechanisms

Despite the structural limitations of the Mexican system, a well-advised buyer can mitigate auction-specific risks through several concrete mechanisms. A full title examination covering at least ten years of Real Property Registry history — with physical inspection of the real property folio for all registered encumbrances, liens, and annotations — is the indispensable baseline. Where the property is located in Quintana Roo’s coastal municipalities, the study must be extended to include verification of restricted zone concessions, ecological reserve designations, and municipal urban development certificates (land use certificates).

Before submitting a bid, strategic buyers should file an ancillary motion before the auction court requesting that all registered creditors be formally notified of the proceeding, thereby ensuring that any preferential claim is surfaced before adjudication rather than after. Engaging a Court Officer to verify the physical status of the property and identify occupants — potential holders of possessory rights — is equally advisable. Post-adjudication, buyers should immediately request a order of possession from the court to formalize physical delivery and should expedite notarization and Real Property Registry inscription to close the vulnerability window created by the gap between judicial and registral title.

Finally, for acquisitions exceeding commercially significant thresholds, title insurance — available in the Riviera Maya through Stewart Title Mexico and First American — provides an important backstop against undiscovered defects, though policy terms must be carefully reviewed to confirm that auction-specific risks, including procedural nullity grounds, fall within coverage.

IBG Legal’s auction practice is distinguished by a documented litigation record in the specific risk categories this article identifies. Our team has successfully obtained nullity of defective auction proceedings on edictos publication grounds before Tribunales Colegiados de Circuito and has defended acquired title in RPP priority disputes where competing encumbrance holders sought to invalidate post-auction registrations. Our integrated PAE-plus-concursal advisory capability allows us to advise institutional buyers simultaneously on the fiscal mechanics of SAT-driven auctions and on the concursal priority architecture governing IFECOM-supervised liquidations — a combination that single-practice litigation boutiques in the Cancún market typically cannot provide within a single engagement. We maintain established working relationships with IFECOM-certified síndicos active in the Riviera Maya insolvency market, enabling rapid due diligence on concursal asset pools. For buyers pursuing coastal fideicomiso rights through enforcement proceedings, our practice covers the full SRE permit and trust substitution sequence identified above as the critical gap between adjudication and operative ownership.

Judicial Criteria

SCJN, First Chamber: thesis characterizing the judicial auction as a compulsory sale producing full property-transfer effects equivalent to a voluntary sale. The doctrine has developed across multiple isolated theses in the Federal Judicial Gazette across different epochs; a single consolidated binding jurisprudence applicable to all circuits and applicable to all auction variants has not been confirmed as of the date of this publication. Practitioners should search the IUS/SJFG database under “AUCTION — COMPULSORY SALE — EFFECTS” to identify the registration numbers applicable to the specific procedural code and auction type at issue. This limitation in citation specificity is expressly acknowledged.
SCJN and Circuit Collegiate Courts: isolated theses establishing nullity of auction proceedings based on failure to comply with mandatory public notices publication requirements and notice intervals. Multiple circuit court theses address this doctrine, and the applicable registration will depend on which procedural code governs the specific proceeding. Practitioners should conduct a targeted search in the Federal Judicial Gazette and its Official Bulletin under “AUCTION — NULLITY — PUBLIC NOTICES” and “AUCTION — PUBLICATION REQUIREMENTS,” filtering by First Chamber and by the relevant Circuit Collegiate Courts. Specific thesis registration numbers are not reproduced here because identifying a single authoritative citation applicable across all procedural variants would misrepresent the state of the jurisprudence; this limitation is expressly acknowledged.
Circuit Collegiate Courts: isolated theses on survival of prior-registered mortgages post-auction under the principle of registration priority in the Property Registry. A governing jurisprudence consolidating this doctrine across all circuits in civil matters has not been definitively confirmed as of the date of this publication. Practitioners should search under “AUCTION — PRIOR MORTGAGE — REGISTRATION PRIORITY” in the IUS database. This limitation in citation specificity is expressly acknowledged.
SCJN, Plenary and First Chamber: theses on patrimonial separateness of trust assets in enforcement proceedings against the trust settlor, distinguishing between attachment of trust beneficiary rights (permissible as personal property of the beneficiary) and attachment of the trust patrimony itself (generally protected). As with the other judicial criteria referenced in this article, practitioners should verify the specific applicable thesis registration in the Federal Judicial Gazette under “TRUST — PATRIMONY — SEPARATENESS — ENFORCEMENT” and “TRUST SETTLOR — TRUST BENEFICIARY RIGHTS — ATTACHMENT,” as the doctrine has developed through multiple isolated theses and the precise holding applicable to coastal restricted zone trusts depends on the enforcement mechanism at issue. This limitation is expressly acknowledged.
