Novation Agreement Mexico (Contrato de Novación)

A Novation Agreement Mexico (Contrato de Novación) is a tripartite or bilateral contract governed by Articles 2213 through 2221 of the Código Civil Federal (CCF) by which an existing obligation is extinguished and a new obligation takes its place — either by substituting the debtor (novación subjetiva pasiva), substituting the creditor (novación subjetiva activa), or changing the object or essential conditions of the obligation (novación objetiva). Article 2213 CCF defines novación as the extinction of an obligation through the creation of a new one that modifies it in one of these fundamental ways. The novación is one of the classic extinction-of-obligations mechanisms in Mexican civil law, alongside payment (pago), condonación, compensación, and prescripción.

The critical legal consequence of novación under CCF Article 2218 is automatic extinguishment of all accessory obligations — avales (commercial guarantees), fianzas (civil guarantees), prendas (pledges), and hipotecas (mortgages) that secured the original obligation are extinguished along with it, unless they are expressly reserved in the novation agreement with the consent of the guarantors and security providers. This automatic extinguishment of accessories distinguishes novación sharply from a mere reestructura de deuda (debt modification), which preserves all existing guarantees. The risk of inadvertent guarantee extinguishment makes the drafting of novation agreements particularly important — a creditor who novates a debt without expressly preserving the existing mortgage may find themselves unsecured.

Article 2215 CCF establishes the requirements for a valid novación: the original obligation must be valid (a void obligation cannot be novated, though an annullable obligation can be novated by the party who could have sought its annulment); the new obligation must be valid; and the parties must have the animus novandi — the clear intent to novate, which under Article 2216 CCF must be expressed explicitly (animus novandi must not be presumed). Mexican courts have consistently held that a mere modification of payment terms without a clear animus novandi does not constitute novación.

Substitution of the debtor (novación subjetiva pasiva) under CCF Articles 2217–2218 is the most commercially significant form of novación in Mexican practice — it occurs when a third party assumes the debt of the original debtor with the creditor's consent, releasing the original debtor from all liability. This mechanism is used in business acquisitions, real estate transfers, and corporate restructurings where the buyer of an asset assumes the seller's existing debt. Without the creditor's express consent to the debtor substitution, the assumption of debt by a third party (asunción de deuda) is only effective between the original and new debtor — it does not release the original debtor from the creditor's claim.

For ISR purposes under the LISR, a novación does not in itself trigger immediate tax consequences — the new obligation is simply a continuation of the economic relationship in modified form. However, if the novación involves a reduction in the amount of the new obligation compared to the original (quita implícita), the debtor may have taxable income under LISR Article 17 Section XIX. If the novación substitutes the debtor (novación subjetiva pasiva) and releases the original debtor, the original debtor's release may trigger tax consequences depending on whether the original debt was deductible by the original debtor — if the original debtor had deducted the interest on the original debt, the release from the obligation may be treated as income recognition under the LISR.

The Ley de Concursos Mercantiles (LCM) uses novación as one of the mechanisms for implementing a convenio concursal — a court-approved insolvency restructuring plan that may substitute new debt instruments for the original obligations of the bankrupt company, effectively novating the original commercial debts into restructured instruments with new terms, new creditors (through debt-to-equity conversion or transfer to a new holding company), or new legal form (converting bank debt to restructured bonds).

A Novation Agreement Mexico is needed whenever the parties to an existing obligation wish to extinguish it and replace it with a fundamentally different new obligation — specifically when they intend to change the debtor, the creditor, or the essential nature of the obligation, and they accept the consequence that all existing guarantees will be extinguished unless expressly preserved.

The agreement is required in business acquisitions (compraventas de negocio) where the buyer assumes the seller's existing debt — under CCF Article 2217, the original debtor is released only if the creditor expressly consents to the substitution. Without the creditor's consent, the buyer's assumption of debt is merely an internal arrangement between buyer and seller that does not release the seller from the creditor's claim.

Novación is needed in real estate transactions where the buyer of a mortgaged property (inmueble gravado) wishes to assume the existing mortgage debt rather than paying it off — the buyer takes over the payments and the original borrower is released from liability. This requires a tripartite novación agreement among the original borrower, the new borrower (buyer), and the mortgage creditor, typically executed by escritura pública before a Notario Público and registered with the Registro Público de la Propiedad.

The document is required in corporate reorganisations (fusiones, escisiones, transformaciones) where the surviving or successor company assumes the debts of the dissolving entity — under the Ley General de Sociedades Mercantiles, a fusión transfers all assets and liabilities by operation of law, but a novación agreement with key creditors confirms the creditor's acceptance of the surviving entity as the new debtor and may improve the surviving company's credit standing.

Novación is needed when the parties wish to change the fundamental nature of an obligation — for example, converting a supply obligation (obligation to deliver goods) into a money payment obligation, or converting a peso-denominated debt into a dollar-denominated debt (subject to applicable BANXICO foreign exchange regulations for peso-dollar contracts between Mexican residents).

The agreement is also used in debt-to-equity conversions (conversión de deuda en capital) — when a creditor agrees to convert their loan claim into shares (acciones) or membership interests (partes sociales) in the debtor company, the original loan obligation is extinguished by novación and replaced with the creditor's equity interest. This is a common restructuring tool in concurso mercantil proceedings and in venture capital financing rounds where convertible notes are converted to equity.

A valid Novation Agreement Mexico under CCF Articles 2213–2221 must contain the following essential elements to effectively extinguish the original obligation and create the new one:

Identification of the Original Obligation: Precise description of the obligation being extinguished — the original loan agreement, pagaré, contract, or other instrument (with its date, parties, amount, and any notarial or registration reference); the outstanding balance; and all accessories (prendas, hipotecas, avales, fianzas). This complete description of what is being novated is essential for establishing that the parties had full knowledge of the original obligation's contents and accessories.

Express Animus Novandi: Under CCF Article 2216, the parties' intent to novate must be expressed explicitly — the agreement must include an unambiguous statement such as 'Las partes declaran expresamente su voluntad de novar la obligación descrita en la Cláusula Primera, extinguiéndola y sustituyéndola por la nueva obligación establecida en la Cláusula Segunda.' Courts have repeatedly held that ambiguous language about modification of terms may be interpreted as reestructura (not extinguishing the original) rather than novación.

Type of Novación: Specify the type of change that constitutes the novación — debtor substitution (novación subjetiva pasiva: 'El acreedor acepta que [New Debtor] sustituye a [Original Debtor] como deudor, liberando a éste de toda responsabilidad'); creditor substitution (novación subjetiva activa: assignment of the credit to a new creditor with debtor notification); or objective novation (novación objetiva: change in the object, currency, amount, or essential conditions of the obligation).

New Obligation Terms: Complete description of the new obligation that replaces the extinguished one — new debtor and creditor identities (if changed); new principal amount in MXN; new interest rate; new repayment schedule; new maturity date; and all other terms of the new obligation. The new obligation must be valid and sufficiently certain to be enforceable — a novación into an indeterminate or impossible obligation is itself void under CCF Article 2215.

Creditor Consent to Debtor Substitution: Under CCF Article 2217, debtor substitution (expromisión or delegación) requires the creditor's express written consent — include the creditor's declaration accepting the new debtor and releasing the original debtor. Without this express consent, the original debtor remains jointly liable with the new assumed debtor.

Treatment of Accessories under CCF Article 2218: Express statement of which accessories are extinguished and which are preserved. The default rule under CCF Article 2218 is that all accessories (prendas, hipotecas, avales, fianzas) are extinguished along with the original obligation unless expressly reserved. Include either: (a) a clause expressly extinguishing all accessories (if the parties intend a clean break); or (b) a clause expressly preserving specified accessories, with the written consent of each guarantor and security provider to continue their obligations under the new terms — without the guarantor's consent, their guarantee cannot be preserved against their will.

Guarantor Consent Sections: If any accessories are being preserved, include separate signature blocks for each avalista, fiador, and prenda or hipoteca provider, with their express declaration that they consent to the novación and confirm that their guarantee continues in force under the terms of the new obligation. This is the most critical risk management element of a novation agreement.

Registration Requirements: If the novación involves a change in a registered security interest — hipoteca, prenda registered with RUG, or assignment of a registered credit — identify the registration steps required: escritura pública before Notario Público; registration with RPP or RUG; notification to the debtor for creditor-substitution novación; and any SAT CFDI requirements for the transaction.
