Commercial Lawsuit Filing Mexico (Demanda Mercantil)

A Commercial Lawsuit Filing Mexico (Demanda Mercantil) is a judicial pleading initiating a formal commercial dispute proceeding before a competent Mexican court under the Código de Comercio (CCom), particularly Articles 1055 through 1063, which establish the general framework for commercial litigation jurisdiction and procedure. The demanda mercantil is the starting document for all commercial proceedings not based on an executive title — it encompasses claims for breach of commercial contract (incumplimiento de contrato mercantil), collection of unpaid commercial invoices (cobro de facturas), enforcement of supply agreements (contratos de suministro), compensation for commercial damages (daños y perjuicios mercantiles), and disputes arising from commercial partnerships, agency relationships, and distribution agreements under the CCom.

Mexican commercial law recognises two primary procedural tracks for commercial litigation under the reformed Código de Comercio. The juicio oral mercantil (oral commercial proceeding) introduced by the Reforma Procesal Mercantil of 2011 applies to disputes with a value of up to 1,000,000 UDIS (Unidades de Inversión, updated daily by Banco de México — approximately MXN 7.8 million at current values). The juicio ordinario mercantil applies to disputes above this threshold and to certain categories of commercial claim that the CCom expressly excludes from the oral track. Articles 1390-A through 1390-J CCom govern the oral procedure, while Articles 1055 through 1063 contain the general rules applicable to both tracks.

Jurisdiction over commercial disputes in Mexico is distributed between federal and state courts. Article 104 of the Constitución Política grants federal courts (Juzgados de Distrito) jurisdiction over federal commercial law — the Código de Comercio is a federal statute — but Article 1104 CCom provides that parties may agree to submit commercial disputes to the state courts of their choice, creating concurrent jurisdiction in most commercial cases. Federal Juzgados de Distrito handle complex commercial cases, banking disputes, and matters involving federal entities. State courts (juzgados civiles con competencia mercantil or juzgados mercantiles in specialised court systems) handle the majority of commercial disputes between private parties.

The territorial competence rules under Articles 1092 through 1108 CCom determine which specific court within the chosen federal or state system has jurisdiction: the court of the defendant's commercial domicile (domicilio mercantil) registered with the Registro Público de Comercio, the court of the place where the commercial obligation was to be performed (lugar de ejecución de la obligación), or the court of the place where the commercial act giving rise to the dispute occurred. Parties to commercial contracts frequently include pactum de foro prorogatum (forum selection clauses) submitting to the courts of Mexico City, Guadalajara, or Monterrey for administrative convenience.

The 2011 Reforma Procesal Mercantil introduced the oral adversarial procedure (juicio oral mercantil) as the default track for qualifying commercial disputes, replacing the written procedure for lower-value claims. The oral procedure features a concentrated two-hearing structure: (1) audiencia preliminar for admissibility rulings, preliminary objections, and parties' attempt at amicable resolution; (2) audiencia de juicio oral where witnesses and experts testify live before the judge, who renders judgment at the end of the session or within 10 days. The reform aimed to reduce the average commercial dispute resolution time from 4 to 6 years (under the prior written procedure) to 12 to 18 months, though actual times vary significantly by court and jurisdiction.

The CCom requires that commercial claims involving amounts above 40 UDIS (approximately MXN 312) be documented in writing with at least a factura (invoice), nota de remisión (delivery note), or pedido (purchase order) — verbal commercial obligations are not enforceable in the juicio mercantil in most circumstances, though they may be proven through witness testimony in exceptional cases. The Reforma Fiscal of 2014 made electronic invoicing (CFDI — Comprobante Fiscal Digital por Internet) mandatory for all commercial transactions above MXN 2,000 under Article 29 of the Código Fiscal de la Federación (CFF), making digital CFDIs the primary documentary evidence in commercial collection lawsuits.

A Commercial Lawsuit Filing Mexico is needed when a commercial creditor or aggrieved party to a commercial transaction cannot resolve a dispute through extrajudicial means — demand letters, commercial negotiation, or PROFECO mediation — and must resort to judicial enforcement of their commercial rights.

The demanda mercantil is the appropriate vehicle when a seller, service provider, or contractor holds commercial invoices (facturas/CFDIs) evidencing delivered goods or completed services for which the buyer or client has not paid within the agreed payment terms, and the invoices alone do not constitute an executive title under Article 1391 CCom — distinguishing this from the juicio ejecutivo mercantil which requires a pagaré, cheque, or notarial acknowledgment.

The lawsuit is necessary when a party to a commercial supply agreement (contrato de suministro), distribution agreement (contrato de distribución), franchise agreement, or commercial agency contract (contrato de agencia comercial) under Articles 273 through 308 CCom has suffered damages from the counterparty's breach — failure to deliver goods, delivery of non-conforming goods, termination without notice, or violation of exclusivity obligations — and seeks both performance and damages.

A demanda mercantil is required when a commercial partnership (sociedad mercantil) dispute arises between socios or accionistas regarding profit distribution, management authority, or shareholder rights under the Ley General de Sociedades Mercantiles (LGSM) — these disputes are commercial in nature and filed before the Juzgado de Distrito o Juzgado Civil con competencia mercantil.

The filing is needed when a guarantor (fiador) on a commercial transaction has honoured the principal debtor's obligation and seeks reimbursement (acción de regreso) from the principal debtor through commercial judicial proceedings.

Where a commercial arbitration clause (cláusula arbitral) exists in the contract, the demanda mercantil may be necessary to request interim protective measures from the court (medidas cautelares) under Article 1425 CCom while the arbitration proceeds, or to enforce an arbitral award (laudo arbitral) through the homologación (recognition) process before the Juzgado de Distrito.

The action is also needed for commercial tort claims — specifically for unfair competition (competencia desleal) under the Ley Federal de Protección a la Propiedad Industrial (LFPPI) and for commercial fraud (fraude comercial) under Articles 386 and 387 Código Penal Federal, which may be pursued civilly and criminally simultaneously.

A valid Commercial Lawsuit Filing Mexico under Código de Comercio Articles 1055–1063 must contain the following essential elements to be admitted by the court and the proceeding to commence.

Identification of Parties and Commercial Standing: Full legal name, RFC (Registro Federal de Contribuyentes), Registro Público de Comercio inscription number, domicilio fiscal, and commercial activity description of the actor (plaintiff). For legal entities (personas morales), identification of the representante legal with their poder notarial details and their own RFC and cédula profesional. Full identification data of the demandado (defendant) with their last known commercial domicile for emplazamiento service.

Commercial Character of the Dispute: Statement of the commercial nature of the acts giving rise to the claim — identifying whether the transaction was a compraventa mercantil (Article 371 CCom), prestación de servicios mercantiles, comisión mercantil (Article 273 CCom), agencia comercial, or other commercial act under Article 75 CCom. This is necessary to establish the court's commercial jurisdiction and distinguish the claim from a civil dispute.

Statement of Facts (Hechos): Chronological narrative of the commercial relationship: (i) formation of the commercial agreement — date, parties, subject matter, essential terms; (ii) performance by the plaintiff; (iii) default or breach by the defendant — specific acts or omissions violating contractual obligations; (iv) notice given to defendant and response; (v) resulting harm and quantum of damages.

Legal Basis (Derecho): Citation of the specific legal provisions supporting each claim — breach of commercial contract under CCom Article 77; commercial damages under Article 2108–2109 CCF as applied supletoriamente; specific contract provisions breached; and the procedural basis for the chosen court track (oral under Article 1390-A CCom or ordinary under Article 1377 CCom).

Relief Requested (Prestaciones): Specific quantified remedies sought: (i) payment of principal owed with supporting invoice/CFDI numbers and dates; (ii) contractual or legal interest from default date; (iii) damages (daños y perjuicios) quantified or subject to expert determination; (iv) return of goods or specific performance; (v) legal costs (costas judiciales) under Article 1084 CCom.

Evidence Attached (Pruebas Documentales): All documentary evidence supporting the claim must be offered in the initial pleading under the oral mercantil procedure — invoices (CFDIs), delivery receipts (notas de remisión), contracts, emails, bank records confirming payments, demand letters with delivery confirmation. Under Article 1061 CCom, documentary evidence not submitted with the initial demanda may not be admitted later except under specified exceptions.

Provisional Measures Request: Where there is risk that the defendant will dissipate assets or destroy evidence before judgment, the plaintiff may request medidas cautelares — asset attachment (embargo precautorio), accounting inspection (exhibición de libros), or evidence preservation — under Articles 1168 through 1180 CCom.

Forms-legal.com provides this Commercial Lawsuit Filing Mexico template as a drafting reference. Commercial litigation in Mexico requires a licensed Licenciado en Derecho experienced in mercantile procedure. The choice between oral and ordinary procedure and the correct characterisation of the commercial claim significantly affect strategy and expected timelines — consulting a specialist in litigación mercantil before filing is strongly recommended.

Pre-Litigation Demand Documentation: Before filing the demanda mercantil, best practice requires sending a formal demand letter with documented delivery confirmation (acuse de recibo or certified courier). While not a statutory prerequisite under the CCom, a documented demand history establishes the default date from which interest accrues and demonstrates good-faith resolution attempts that courts consider when awarding costas under Article 1084 CCom.

Arbitration Clause Review: Before filing, the attorney must review the commercial contract for any clausula arbitral. If present, the Juzgado Mercantil must stay proceedings under CCom Article 1424 and refer parties to arbitration under the Ley de Arbitraje Comercial Internacional or CCom Chapter XI. Failure to identify an arbitration clause before filing results in procedural dismissal and lost filing fees.
