In particular, the principle of limited judicial intervention is mandatory, as courts may only intervene in arbitration matters in the cases expressly provided by law (Article 1421). The equal treatment of the parties and their right to a full opportunity to present their case is also mandatory (Article 1434).<\/p>\n<p>In addition, the rules governing arbitrability and public policy operate as non-derogable limits to arbitration. An award may be set aside or denied recognition if the dispute is not capable of settlement by arbitration under Mexican law or if the award violates public policy (Articles 1457 and 1462). Likewise, the grounds for setting aside an award and for refusing recognition or enforcement are exhaustive and may not be expanded by agreement (Articles 1457 and 1462).<\/p>\n<p>These mandatory provisions ensure that arbitration in Mexico is conducted within a framework that safeguards fundamental procedural guarantees while preserving a pro-arbitration approach.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">Is your country a signatory to the New York Convention?

Mexican arbitration law is substantially based on the UNCITRAL Model Law, with minor adaptations. There are no material deviations affecting core principles such as competence-competence, separability, or limited judicial intervention.<\/p>\n<p>One of the most significant departures from the Model Law concerns interim measures. In particular, the last paragraph of Article 1480 of the Commerce Code expressly provides that liability for interim measures rests not only with the party requesting the measure, but also with the arbitral tribunal that grants it, making both responsible for any damages caused. This allocation of liability goes beyond the approach of the UNCITRAL Model Law and has been viewed in practice as a factor that may make arbitral tribunals more cautious when granting interim relief even though such provision is not mandatory and there is no registered case law where such provision has been applied.<\/p>\n<p>No comprehensive reform is currently pending, although courts continue to refine interpretation through case law.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">What arbitral institutions (if any) exist in your country?

The CANACO Arbitration Rules, originally issued in 2000 and last amended in 2012, also provide for urgent interim measures before the tribunal is constituted, in addition to a simplified and low-cost arbitration procedure for disputes below 128,000 Investment Units (Unidades de Inversi\u00f3n), equivalent to approximately USD 57,000.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">Is there a specialist arbitration court in your country?<\/h3>\r\n\t\t\t\t\t\t<button id=\"show-me\">+<\/button>\r\n\t\t\t\t\t\t<div class=\"question_answer filter-container__match-html\" style=\"display:none;\"><p>The judiciary of the state of Yucat\u00e1n has approved the establishment of the first specialised court for arbitration and alternative dispute resolution (ADR) which is in the process of appointing the judge who will preside such specialized court and start funtioning.<\/p>\n<p>This court would have exclusive jurisdiction over all arbitration-related matters, including judicial assistance in arbitral proceedings and the recognition or annulment of domestic and international awards.

In particular, Mexican courts may assess whether the clause was agreed in a true negotiation context or forms part of a contract of adhesion, and whether the party lacking the option to choose between arbitration and litigation had a real opportunity to negotiate or reject the clause. Where a significant preponderant position exists and the clause results in a substantive restriction of access to justice or procedural equality, courts may be more inclined to question its validity or enforceability.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">In what instances can third parties or non-signatories be bound by an arbitration agreement?

Where the parties have not made an express choice, arbitral tribunals seated in Mexico determine the applicable law by resorting to conflict-of-laws principles deemed appropriate to the circumstances of the case.<\/p>\n<p>Mexican federal courts have consistently held that conflicts of laws arise where a legal relationship contains elements connecting it to more than one legal system, whether domestic or international, and that the role of the adjudicator is to identify the legal system applicable to the dispute rather than to reconcile conflicting norms as such. In this context, courts have recognised that the application of foreign law is justified where the governing conflict-of-laws rules so require, and that the choice between the law of the forum and a foreign law depends on the connecting factors of the legal relationship.<\/p>\n<p>In addressing conflicts between potentially applicable norms, Mexican courts have also identified a series of interpretative and conflict-resolution criteria, including hierarchical, chronological and speciality criteria, as well as competence-based and interest-balancing approaches. These principles inform the manner in which arbitral tribunals and courts analyse and resolve conflicts of laws in the absence of a clear choice by the parties, always subject to mandatory rules and public policy considerations.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">In your country, are there any particular requirements for and\/or restrictions in the appointment of arbitrators?<\/h3>\r\n\t\t\t\t\t\t<button id=\"show-me\">+<\/button>\r\n\t\t\t\t\t\t<div class=\"question_answer filter-container__match-html\" style=\"display:none;\"><p>In Mexico, there are no nationality or professional restrictions on the appointment of arbitrators.

Court intervention is permitted solely in the cases expressly provided by law and generally arises where the appointment mechanism agreed by the parties has failed.<\/p>\n<p>In particular, under Article 1426, where the parties have not agreed on a procedure for appointing arbitrators, or where the agreed procedure cannot be implemented, a party may request the competent court to make the necessary appointment. Likewise, in multiparty or multi-arbitrator scenarios, courts may intervene if the parties fail to agree on the constitution of the arbitral tribunal within the statutory or agreed time limits.<\/p>\n<p>Judicial intervention is also available in connection with challenges to arbitrators. Pursuant to Articles 1428 and 1429, if a challenge based on lack of independence, impartiality, or agreed qualifications is not resolved within the arbitral process, the challenging party may request the competent court to decide the challenge, whose decision is final and not subject to appeal.<\/p>\n<p>Beyond the appointment and challenge of arbitrators, Mexican courts may assist the arbitral process in other limited circumstances expressly provided by law, such as the granting or enforcement of interim measures (Articles 1478 to 1480) and the taking of evidence (Article 1444).

The appointment of an arbitrator may be challenged under Mexican law. Pursuant to Article 1428 of the Commerce Code, an arbitrator may be recused where circumstances exist that give rise to justifiable doubts as to their independence or impartiality, or where the arbitrator does not possess the qualifications agreed by the parties.<\/p>\n<p>The procedure for challenging an arbitrator is primarily governed by the parties\u2019 agreement or the applicable institutional rules. In the absence of agreement, Articles 1428 and 1429 provide that the challenge must first be decided by the arbitral tribunal. If the challenge is rejected, the challenging party may request the competent court to decide the matter.

This duty of disclosure is ongoing and forms a central safeguard of due process in arbitration.<\/p>\n<p>While Mexican courts have not developed an extensive body of case law elaborating substantive standards of independence or impartiality beyond the statutory framework, there is one relevant federal decision addressing the legal consequences of a successful challenge to an arbitrator arising of a lack of impartiality. In a 2021 decision issued by the Eleventh Civil Collegiate Court of the First Circuit (Und\u00e9cima \u00c9poca), the court held that a judicial decision upholding the challenge of an arbitrator on grounds of partiality may adversely affect the arbitrator\u2019s moral and economic interests, as well as their professional reputation, given that arbitrators act as independent service providers and may face liability and loss of remuneration as a result of such a declaration.<\/p>\n<p>This decision underscores the seriousness with which Mexican courts view the duties of independence and impartiality, even though developments in this area remain largely anchored in the statutory provisions of the Commerce Code rather than in a broader or more detailed jurisprudential framework.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">Are arbitrators immune from liability?<\/h3>\r\n\t\t\t\t\t\t<button id=\"show-me\">+<\/button>\r\n\t\t\t\t\t\t<div class=\"question_answer filter-container__match-html\" style=\"display:none;\"><p>Mexican law does not provide for a general or absolute immunity of arbitrators. The Commerce Code does not expressly grant arbitrators immunity from civil liability, and arbitrators may be exposed to responsibility in cases of bad faith, misconduct, gross negligence, lack of independence or impartiality, or breach of their duties under the applicable law. While civil liability may be waived by the parties or such waiver be included in the relevant arbitration rules, under Mexican law misconduct (dolo) and gross negiligence (negligencia grave) are not considered waivable even if there is an agreement or document in such regard.<\/p>\n<p>In particular, Article 1480 of the Commerce Code expressly addresses liability in connection with interim measures. Its last paragraph provides that responsibility for interim measures lies both with the party requesting the measure and with the arbitral tribunal that grants it, and that they are jointly responsible for any damages caused. This provision represents a significant departure from other arbitration regimes and underscores that arbitrators in Mexico may, in certain circumstances, face potential liability arising from the exercise of their functions. This provision is considered as being subject to a waiver under Mexican law.<\/p>\n<p>Accordingly, while arbitrators are generally protected from liability for decisions taken in good faith within the scope of their adjudicatory role, Mexican law does not recognise a doctrine of full arbitral immunity, and liability risks may arise in exceptional cases.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">Is the principle of competence-competence recognized in your country?<\/h3>\r\n\t\t\t\t\t\t<button id=\"show-me\">+<\/button>\r\n\t\t\t\t\t\t<div class=\"question_answer filter-container__match-html\" style=\"display:none;\"><p>Yes. The principle of competence-competence is expressly recognised under Mexican arbitration law and is regulated in Article 1432 of the Commerce Code, which provides that the arbitral tribunal may rule on its own jurisdiction, including any objections with respect to the existence or validity of the arbitration agreement. The same provision expressly adopts the principle of separability, clarifying that an arbitration agreement forming part of a contract shall be treated as an agreement independent of the other contractual terms.<\/p>\n<p>Mexican law recognises competence-competence in both its positive and negative effects. The positive effect allows arbitral tribunals seated in Mexico to decide, in the first instance, on challenges to their jurisdiction. The negative effect is reflected in the obligation of courts to refrain from ruling on the merits of the tribunal\u2019s jurisdiction at the outset of the dispute and to refer the parties to arbitration when a valid arbitration agreement prima facie exists, unless the agreement is manifestly null or inoperative. This approach is consistent with the principle of limited judicial intervention set out in Article 1421 of the Commerce Code.<\/p>\n<p>In practice, jurisdictional objections are typically resolved by arbitral tribunals as preliminary matters or together with the merits, subject to limited judicial review at the annulment or enforcement stage, in accordance with the exhaustive grounds provided in Articles 1457 and 1462 of the Commerce Code.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">What is the approach of local courts towards a party commencing litigation in apparent breach of an arbitration agreement?<\/h3>\r\n\t\t\t\t\t\t<button id=\"show-me\">+<\/button>\r\n\t\t\t\t\t\t<div class=\"question_answer filter-container__match-html\" style=\"display:none;\"><p>Mexican courts generally adopt a pro-arbitration approach when faced with litigation initiated in apparent breach of an arbitration agreement. This approach is primarily grounded in the principle of limited judicial intervention set out in Article 1421 of the Commerce Code, pursuant to which courts may only intervene in arbitration matters in the cases expressly provided by law.<\/p>\n<p>In particular, where a party commences court proceedings despite the existence of an arbitration agreement, Mexican courts are required to decline jurisdiction and refer the parties to arbitration, provided that the arbitration agreement is not manifestly null, inoperative or incapable of being performed. This obligation is reflected in Article 1432, which recognises the arbitral tribunal\u2019s authority to rule on its own jurisdiction and implicitly requires courts to refrain from deciding jurisdictional issues at the merits stage when an arbitration agreement exists.<\/p>\n<p>In practice, courts typically limit their analysis to a prima facie review of the arbitration agreement, focusing on its existence and apparent validity, without engaging in a full assessment of jurisdiction or merits. If the court concludes that a valid arbitration agreement exists, the judicial proceedings are dismissed or stayed, and the parties are referred to arbitration.<\/p>\n<p>Mexican law does not expressly provide for nor prohobit anti-suit injunctions.

This discretion is designed to allow courts to tailor interim relief to the specific circumstances of each case, given the diverse and unpredictable situations that may arise in arbitration-related proceedings. Courts may adopt provisional, flexible and even modifiable measures throughout the proceedings, provided that such measures are reasoned, proportionate and consistent with due process and the purpose of interim relief, namely to preserve the effectiveness of a future decision on the merits.<\/p>\n<p>Mexican courts have also clarified that interim measures may be granted not only prior to or during the arbitral proceedings, but also within the special proceedings for the recognition and enforcement of arbitral awards, including after the arbitral tribunal has rendered its award, for the purpose of securing the effectiveness of a potential enforcement decision.<\/p>\n<p>However, judicially ordered interim measures are subject to important substantive limits. Courts have consistently held that interim relief may not be used to alter, suspend or effectively nullify contractual rights agreed by the parties, nor to anticipate the resolution of the merits of the dispute. Interim measures are intended to preserve an existing factual or legal situation and may not constitute innovative relief that creates new rights or allows one party to unilaterally avoid its contractual obligations, as such determinations are reserved for the arbitral tribunal when deciding the merits.<\/p>\n<p>Mexican law does not provide for anti-suit or anti-arbitration injunctions in the strict sense.

Likewise, tribunals may also award pre-award and post-award interest on the costs incurred, including legal fees and expenses, where deemed appropriate.

In a 2025 decision issued by the Sixteenth Civil Collegiate Court of the First Circuit, the court held that provisional measures aimed at securing the payment of the amount awarded in an arbitral award may be ordered during enforcement proceedings, pursuant to a teleological interpretation of Article 1425 of the Commerce Code.

As a general reference, uncontested proceedings may be resolved within approximately six to twelve months. However, in contested cases the timeline has effectively been extended by the availability of constitutional remedies. In particular, pursuant to binding Supreme Court precedent, decisions rendered in annulment or enforcement proceedings may be challenged through an indirect amparo action, followed by a review appeal (recurso de revisi\u00f3n), which introduces an additional judicial layer and may significantly prolong the overall duration of the process.<\/p>\n<p>Recognition and enforcement proceedings are typically initiated on an ex parte basis through the filing of the relevant application and supporting documentation. Once the respondent is served, the proceedings become adversarial and the respondent may raise the limited objections permitted under the Commerce Code.<\/p>\n<p>The standard of judicial review is substantially the same for domestic and international arbitral awards. In both cases, courts are confined to examining the exhaustive statutory grounds for refusal or annulment and do not review the merits of the dispute or the tribunal\u2019s factual or legal determinations.

These grounds include, among others, the absence of a valid arbitration agreement, violations of due process, excess of authority by the arbitral tribunal, non-arbitrability of the dispute, or contravention of public policy. Judicial review in annulment proceedings is strictly confined to these procedural and jurisdictional grounds and does not involve a re-examination of the merits.<\/p>\n<p>In addition to annulment proceedings, the Commerce Code provides for limited post-award remedies before the arbitral tribunal itself that do not constitute challenges to the award. Pursuant to Articles 1450 and 1451, either party may request the tribunal, within thirty days of receipt of the award, to correct clerical, typographical or computational errors, to interpret specific portions of the award, or to issue an additional award in respect of claims raised in the arbitration but omitted from the award. These mechanisms are intended to clarify or complete the award and do not entail a reconsideration of the tribunal\u2019s substantive determinations.<\/p>\n<p>Mexican law does not expressly regulate the waiver of annulment or enforcement challenges. In principle, there is no categorical prohibition against parties agreeing to waive or limit certain grounds for setting aside or opposing enforcement of an arbitral award, particularly those grounds that are not subject to ex officio review by the courts. However, grounds related to public policy and arbitrability\u2014over which courts retain the power to review on their own motion\u2014are generally considered non-waivable.

Judicial analysis focuses on the status of the award at the seat of arbitration, including whether it has been set aside or suspended by a competent authority, and on whether any of the limited statutory grounds for refusing recognition or enforcement are met. The review remains confined to those grounds and does not extend to a reconsideration of the merits.<\/p>\n<p>By way of illustration, one of the most significant cases involving a Mexican-seated arbitral award is Commissa v.

Notwithstanding that annulment, courts in New York enforced the award, exercising the discretion afforded under Article V(1)(e) of the New York Convention. The U.S. courts concluded that the Mexican annulment resulted from the retroactive application of public law considerations incompatible with fundamental principles of international arbitration and due process, and that giving effect to the annulment would contravene the international public policy of the enforcement forum. Although not recent, the Commissa case remains a widely cited reference illustrating the potential divergence between annulment at the seat and enforcement abroad in exceptional circumstances.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">Have there been any recent court decisions in your country considering the issue of corruption?

In practice, Mexican courts and arbitral tribunals require a high threshold of proof. General allegations or suspicions are insufficient, and the party alleging corruption bears the burden of proving it with clear and convincing evidence. Courts are reluctant to infer corruption absent concrete and substantiated proof, particularly where doing so would entail revisiting the merits of the dispute.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">Have there been any recent court decisions in your country with respect to intra-European investor-State arbitration generally or enforcement of awards stemming from proceedings of this nature?

Institutional rules and administrative practices now commonly allow for electronic filings, digital case management, and remote communications between tribunals, parties and institutions. These developments reflect a broader trend toward procedural flexibility and cost-effective arbitration.<\/p>\n<p>Virtual and hybrid hearings have become widely accepted in arbitrations seated in Mexico, particularly following the experience gained during the COVID-19 pandemic. Arbitral tribunals regularly conduct procedural conferences, witness hearings and expert examinations by videoconference, either by agreement of the parties or pursuant to the tribunal\u2019s procedural authority. Such practices are now viewed as a standard option rather than an exception.<\/p>\n<p>While the Commerce Code does not expressly regulate the use of technology or virtual hearings, Mexican arbitration law affords tribunals broad discretion to conduct proceedings in the manner they consider appropriate, subject to due process and equality of the parties. As a result, the use of virtual hearings and other technological tools is firmly established in practice and continues to play a significant role in enhancing efficiency in both domestic and international arbitrations seated in Mexico.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\t\t\t\t\t<li class=\"question-block filter-container__element\">\r\n\t\t\t\t\t\t<h3 class=\"filter-container__match-html\">Have there been any recent developments in your jurisdiction with regard to disputes involving ESG issues such as climate change, sustainability, social responsibility and\/or human rights?<\/h3>\r\n\t\t\t\t\t\t<button id=\"show-me\">+<\/button>\r\n\t\t\t\t\t\t<div class=\"question_answer filter-container__match-html\" style=\"display:none;\"><p>Mexico has not yet developed a distinct body of arbitration-specific case law focused exclusively on ESG-related disputes.

The Commerce Code does not address the use of AI tools in arbitral proceedings, and there is currently no arbitration-specific statutory framework regulating these technologies.<\/p>\n<p>Nevertheless, recent developments within the legal profession reflect a growing awareness of the ethical and practical implications of AI. In particular, the Barra Mexicana, Colegio de Abogados, A.C. (BMA) has issued non-binding Guidelines for the Responsible Use of Artificial Intelligence in the Practice of Law. These guidelines articulate ethical principles applicable to the use of AI by legal professionals, including duties of human verification, confidentiality and data protection, transparency, avoidance of bias, preservation of professional judgment, and responsibility for AI-assisted work. While not legally binding, these guidelines are increasingly influential as a professional reference point and may inform best practices in arbitration-related work.<\/p>\n<p>In practice, the use of AI tools in arbitrations seated in Mexico is governed by general legal principles such as due process, equality of the parties, confidentiality, professional responsibility and data protection. Arbitral tribunals retain discretion to regulate the use of AI on a case-by-case basis through procedural orders or party agreements, and it is expected that soft law instruments and professional guidelines\u2014such as those issued by the BMA\u2014will continue to shape the responsible use of AI in international arbitration involving Mexican practitioners.<\/p>\n<\/div>\r\n\r\n\r\n\t\t\t\t\t<\/li>\r\n\r\n\t\t\t\t\r\n<div class=\"word-count-hidden\" style=\"display:none;\">Estimated word count: <span class=\"word-count\">8322<\/span><\/div>\r\n\r\n\t\t\t<\/ol>\r\n\r\n<script type=\"text\/javascript\" src=\"\/wp-content\/themes\/twentyseventeen\/src\/jquery\/components\/filter-guides.js\" async><\/script><\/div>"}},"_links":{"self":[{"href":"https:\/\/my.legal500.com\/guides\/wp-json\/wp\/v2\/comparative_guide\/127896","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/my.legal500.com\/guides\/wp-json\/wp\/v2\/comparative_guide"}],"about":[{"href":"https:\/\/my.legal500.com\/guides\/wp-json\/wp\/v2\/types\/comparative_guide"}],"wp:attachment":[{"href":"https:\/\/my.legal500.com\/guides\/wp-json\/wp\/v2\/media?parent=127896"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
