A foreign bank holding a loan against a Mexican borrower discovers, midway through insolvency proceedings, that the borrower simultaneously holds deposit accounts at the same institution. The instinct – net the positions and walk away – collides immediately with the procedural machinery of Mexican insolvency law. That collision defines one of the most consequential and under-examined creditor problems in cross-border restructuring across the Americas.
Set-off rights in Mexican insolvency proceedings arise at the intersection of civil law doctrine and specialised insolvency legislation. Their exercise is conditional on the mutual obligations being liquid, due, and of the same kind at the moment the insolvency proceeding is formally opened. Once the proceeding commences, unilateral set-off is frozen, and any creditor seeking to rely on this right must submit it through the proof of debt process and withstand review by the administrator.
This analysis examines the doctrinal foundations of set-off under Mexican law, the competing interpretations that courts and practitioners have advanced, the practical gap between statute and administration. The cross-border complications that arise most frequently for international creditors. Additionally, the strategic approaches that have proved most durable in practice.
Doctrinal foundations: civil law roots and the insolvency overlay
Set-off – known in Mexican legal tradition as compensación (the extinguishment of mutual obligations up to their overlapping amount) – has its roots in civil legislation. The civil law conception requires three conditions to be met simultaneously. Both obligations must be due. Both must be liquid – meaning their amounts are certain or readily ascertainable. And they must be of the same kind, typically monetary.
These conditions operate smoothly in ordinary commercial transactions. When a company enters insolvency proceedings under Mexico's specialised insolvency legislation – commonly referred to as the Ley de Concursos Mercantiles (Mexico's commercial insolvency law, or LCM) – the picture changes. The LCM introduces a stay on creditor actions. It creates a supervised collective process governed by the síndico (administrator or trustee appointed to manage and supervise the debtor's estate) and. In the conciliation phase, by the conciliador (conciliator, a specialist appointed to facilitate a restructuring plan between debtor and creditors).
The moment the court issues the declaration of concurso mercantil (formal insolvency, roughly equivalent to the opening of restructuring or liquidation proceedings). The mutual obligations between debtor and creditor are frozen at their values as of that date. Interest on unsecured obligations generally ceases to accrue. The creditor's ability to act unilaterally – including by offsetting what the debtor owes against what the creditor owes – is suspended.
This suspension reflects a core tension in Mexican insolvency legislation. On one hand, civil legislation treats compensación as a substantive right that arises automatically once the three conditions are met. On the other hand, insolvency legislation treats the opening of proceedings as the moment that crystallises rights and subordinates individual creditor action to collective procedure. Which principle prevails – and when – is where doctrinal disagreement has been sharpest.
Competing court interpretations and the pre-commencement question
Mexican courts have not spoken with a single voice on the central question: can a set-off that was already perfected before the declaration of concurso mercantil survive the stay?
One line of reasoning holds that if both obligations were liquid, due, and of the same kind before the declaration date, the compensación arose automatically by operation of civil legislation. Under this view, there is nothing left to stay. The obligations were already extinguished. The administrator's role is merely to acknowledge the pre-existing extinction and adjust the proof of debt accordingly.
A competing line of reasoning is more cautious. Courts in this tradition note that the stay under insolvency legislation is designed precisely to prevent a subset of creditors from improving their position in the period before and during the formal proceeding. Under this view, even a technically perfected set-off must be presented through the proof of debt process so that the administrator can verify it. Check for retroacción (the look-back period during which transactions may be challenged or set aside). Additionally, confirm that the creditor did not obtain an unfair preference.
The dominant approach in practice leans toward the second view. The síndico and the conciliador routinely require creditors to substantiate set-off claims through the formal proof of debt submission, even where the creditor argues that the conditions were met before the declaration date. Practitioners in Mexico consistently note that relying on the first view – presenting a set-off as a fait accompli – creates significant risk. If the administrator disagrees and the supervising court sides with the estate, the creditor may find itself holding an unsecured claim in the mass, having already "applied" the set-off and lost the benefit.
A further complication arises with contingent or unliquidated claims. Where the creditor's obligation to the debtor is contingent – for example, an undrawn credit facility or an indemnity obligation whose amount is disputed – the liquidity condition is not met at the declaration date. Courts have generally refused to permit set-off against contingent obligations. The creditor must wait for the obligation to crystalise. By that point, the restructuring plan may already be under discussion at the creditors meeting, and the creditor's leverage is reduced.
For a comparative perspective on how set-off doctrine plays out in a common law insolvency system. See our analysis of insolvency set-off in the United States. This highlights the divergence in mutuality tests and automatic stay mechanics.
The gap between statute and practice: what the administrator actually does
The most consequential gap in Mexican insolvency set-off is not doctrinal. It is procedural and practical. International creditors frequently underestimate how much discretion the administrator holds in the early stages of insolvency proceedings.
When a creditor files a proof of debt incorporating a set-off argument, the administrator reviews it against the debtor's books, the creditor's own documentation, and the broader claims pool. Several issues arise with regularity.
First, documentation gaps. Mexican courts expect set-off claims to be supported by detailed contractual documentation, account statements, and evidence that the obligations met all three civil law conditions as of the declaration date. International creditors sometimes present summaries rather than primary documents. The administrator may provisionally disallow the set-off and treat the full gross amount of the creditor's debt to the estate as an ordinary liability.
Second, currency mismatches. Many cross-border transactions involve obligations denominated in US dollars on one side and Mexican pesos on the other. Insolvency legislation requires conversion to a common currency as of the declaration date. Disputes over applicable exchange rates have led to material differences between what the creditor claims as the net position and what the administrator calculates. This is not a minor technical issue: a significant exchange rate movement between the contract date and the declaration date can transform a near-complete set-off into a partial one.
Third, the look-back challenge. The LCM empowers the administrator and courts to set aside transactions completed within a defined period before the declaration date where those transactions caused harm to the general body of creditors. A set-off effected in the months before the opening of insolvency proceedings may be scrutinised under this look-back provision. If the court determines that the creditor exercised set-off knowing the debtor was already in financial difficulty, the transaction may be unwound. The creditor then finds itself as an ordinary unsecured creditor for the full amount.
Fourth, the role of the creditors meeting. The junta de acreedores (creditors meeting) is the forum where the restructuring plan is debated and voted on. Creditors whose set-off claims are disputed may find their voting rights affected. A creditor whose claim is admitted only provisionally – pending resolution of the set-off dispute – may vote on a reduced basis, weakening its influence over the outcome of the restructuring plan.

Cross-border implications for Americas clients
Most set-off disputes in Mexican insolvency proceedings with a meaningful strategic dimension involve cross-border elements. Three scenarios recur with particular frequency.
US parent companies and Mexican subsidiaries. A US parent may hold intercompany loans advanced to its Mexican subsidiary. The subsidiary simultaneously owes management fees, royalties, or dividend arrears to the parent. When the subsidiary enters concurso mercantil, the parent seeks to set off the intercompany receivables against its own obligations. Mexican courts have approached these situations with caution. Intercompany transactions are subject to heightened scrutiny under the look-back provisions. The administrator will examine whether the intercompany pricing was at arm's length and whether the loan terms were commercially reasonable. A set-off that the parent regards as straightforward may be challenged on the basis that the underlying transactions were designed to extract value from the Mexican entity before insolvency.
Trade finance and supply chains. A supplier holding receivables for goods delivered to a Mexican buyer may also owe the buyer for advances received under a supply agreement. The supplier's natural instinct is to net these positions. In practice, the supplier must file a proof of debt for the full receivable amount and separately account for the advance. The administrator will determine whether the supplier's debt to the estate. the unrepaid advance. should be treated as a liability subject to set-off or as a priority claim that must be repaid in full outside the restructuring plan.
Financial institutions with netting agreements. Banks and dealers operating under master netting agreements – including ISDA documentation – face a distinct challenge. Mexican insolvency legislation does not fully replicate the safe harbour provisions that US and EU law extend to financial contracts. The enforceability of close-out netting under an ISDA master agreement in a Mexican concurso mercantil is not settled beyond doubt. Courts have generally respected netting agreements where they are expressly and clearly documented. However. Practitioners in Mexico note that the administrator retains the right to challenge the characterisation of individual transactions as forming part of the netting set.
The cross-border dimension also engages questions of applicable law and recognition. Where the creditor is incorporated in a foreign jurisdiction and the set-off agreement is governed by foreign law. New York law. English law. the administrator may initially apply Mexican insolvency legislation to override the foreign law provision. The creditor must then argue, through the supervising court, that the foreign law governing the agreement should be respected. This argument has a better prospect of success where the parties expressly chose foreign law in a commercial context, but it is not automatic.

Strategic recommendations for creditors in restructuring
Given the doctrinal uncertainty and the administrator's broad practical discretion, creditors with potential set-off positions in a Mexican insolvency should take a sequenced and well-documented approach.
Before the declaration of concurso mercantil, the priority is to ensure that any set-off right is as clearly perfected as possible. This means confirming in writing – through contractual notices, account statements, or formal demand letters – that both obligations are liquid, due, and of the same kind. Where a creditor has advance knowledge that its counterparty is in financial difficulty, acting promptly is important. A set-off exercised well before the declaration date is substantially less exposed to the look-back challenge than one effected in the weeks immediately preceding the formal opening.
Once insolvency proceedings commence, the creditor should file a detailed proof of debt that explicitly addresses the set-off claim. The proof of debt should attach all primary contractual documents, account statements with balance confirmations, and evidence of the conditions being met as of the declaration date. A net figure should be presented, but the gross amounts and the basis for netting must be set out transparently. Creditors who present only the net figure without supporting the gross calculation invite the administrator to reject the set-off element and treat the gross debt owed to the estate as a full liability.
Engagement with the administrator early in the process is consistently more productive than a confrontational posture. The administrator has discretion in how provisional claims are classified and how disputed set-off claims affect voting rights at the creditors meeting. Creditors who invest in a constructive working relationship – providing documentation promptly, responding to queries without delay – tend to see their provisional admissions resolved faster.
Where the set-off involves foreign law documents or foreign currency obligations, specialist advice is necessary before the proof of debt is filed. The characterisation of the claim – which law governs, how currency conversion is presented, whether the netting agreement qualifies as an enforceable set-off under Mexican insolvency legislation – has material consequences for the ultimate recovery.
For creditors with significant exposures, participation in the creditors meeting through an active and coordinated strategy can influence the terms of the restructuring plan. A creditor whose set-off claim has been provisionally admitted at full value holds a stronger voting position. This can be relevant where the restructuring plan proposes treatment of the creditor's claim that diverges from what the set-off would have produced outside insolvency.
Finally, creditors should assess whether the insolvency proceeding may benefit from recognition in a foreign jurisdiction. Where the debtor has assets or operations in the United States, recognition under cross-border insolvency principles may affect how the set-off is treated and whether a stay in Mexico is enforced against assets held abroad.

Outlook: where Mexican insolvency set-off law is heading
Mexican insolvency legislation has been subject to periodic reform since the early 2000s, and practitioners anticipate further development in the treatment of financial contracts and netting arrangements. The direction of travel in comparative insolvency law. including in neighbouring jurisdictions and in international instruments addressing cross-border insolvency. points toward greater recognition of contractual netting arrangements and stronger safe harbours for financial market participants.
There is a developing body of court decisions, still not fully crystallised, that takes a more receptive approach to well-documented set-off claims, particularly in financial sector insolvencies. Courts have shown increased willingness to respect contractual netting terms where the documentation is comprehensive and the parties are sophisticated commercial entities.
At the same time, the administrator's investigative powers over pre-insolvency transactions are unlikely to be curtailed. The look-back provisions exist to protect the general body of creditors, and this protective function enjoys strong institutional support. The creditor who attempts to extract value through set-off in the run-up to insolvency should not expect reform to eliminate that risk.
For international creditors, the practical implication is that investment in contractual architecture – clear netting provisions, governing law clauses, account control agreements, and early-exercise mechanisms – remains the most reliable protection. Litigation over set-off inside a Mexican concurso mercantil is costly, slow, and uncertain. Prevention is substantially less expensive than recovery.
Clients with ongoing exposure to Mexican counterparties should review their credit documentation against these standards as a matter of current portfolio management, not as a reactive measure after insolvency is declared.

Frequently asked questions
Q: Can a creditor exercise set-off rights automatically once insolvency proceedings are opened in Mexico?
A: No. Under Mexico's insolvency legislation, the opening of formal insolvency proceedings triggers a stay that significantly restricts unilateral creditor action. A creditor cannot simply net off mutual obligations without satisfying the conditions established under the applicable law and, frequently, without the concurrence of the administrator. Courts in Mexico have consistently held that any set-off attempted after the formal commencement date requires judicial validation.
Q: How long does it typically take for a set-off claim to be resolved within Mexican insolvency proceedings?
A: Timeline varies considerably. A creditor submitting a proof of debt that incorporates a set-off argument can expect the administrator's initial review to take several weeks to a few months. If the administrator challenges the claim, resolution before the supervising court can extend to a year or more, particularly where the debts involve cross-border elements or contested valuation. Early engagement with the administrator and thorough documentation significantly reduce delays.
Q: Is it a misconception that set-off in Mexican insolvency operates the same way as in US Chapter 11 proceedings?
A: Yes, and it is a common mistake among international creditors. Engaging a lawyer in Mexico with cross-border restructuring experience is essential here. US bankruptcy law permits automatic set-off subject to court relief from stay, whereas Mexican insolvency legislation imposes stricter pre-conditions and grants the administrator broader powers to challenge or disallow set-off. The doctrinal roots differ: Mexico's civil law tradition treats set-off as a substantive right requiring both obligations to be liquid and due, while US law focuses on the mutuality test.
