An expired suretyship is not an extinguished suretyship: the *Cour de cassation* (French Supreme Court for civil and criminal matters) requires it to be included in the overall debt of the surety called upon to pay.

Analysis of a ruling Cass. com., July 8, 2026, no. 25-16.540, by Pierre-Louis Roquet, a lawyer focused on business law in Lyon.

A loan of 70,000 euros, granted to a company on September 7, 2011, by its bank. Two directors who stood as joint and several sureties for up to 84,000 euros, including principal, interest, and late payment penalties. Then redressement judiciaire (court-ordered reorganization), liquidation (liquidation), and a summons to pay issued on August 3, 2021. The scenario is commonplace. What follows is less so.

Before the Court of Appeal, the surety won the first round. Their commitment was manifestly disproportionate to their assets and income on the day they signed it. The second question remained, that of the return to better fortune: did the director's assets, on the day they were called upon, allow them to meet their obligation? To answer this, the lower court judges dismissed one by one the suretyships previously entered into. Those from May 2010 to the benefit of another institution, granted for six years: expired. That of 2006 guaranteeing a loan of 210,000 euros over nine years: expired, like the guaranteed credit whose last installment fell due in May 2013. The aval (guarantee on a bill of exchange or promissory note) given in December 2012 on an 80,000 euro cash credit: expired at the end of 2013. Expired, therefore non-existent. The director's assets suddenly seemed comfortable, and they were ordered to pay 38,815.33 euros.

The Commercial Chamber overturned this reasoning. It did so under the former articles 1134 and 2292 of the Civil Code and article L. 341-4 of the Consumer Code. The decision was published in the Bulletin.

The expiry of a suretyship does not erase debt incurred before it

The solution rests on a distinction that every suretyship practitioner knows, and that lower court judges sometimes forget: that between the obligation of coverage and the obligation of payment.

The obligation of coverage defines the scope of the guarantee over time. It determines which debts of the principal debtor fall within the scope of the suretyship. When the agreed term occurs, this obligation ceases: debts incurred after this date are not covered by the suretyship. The obligation of payment, on the other hand, concerns debts already within the scope. It survives the term. The creditor can demand its execution as long as the principal debt is not extinguished and the limitation period cannot be raised against them.

The Cour de cassation states the rule unequivocally. In the absence of an express contractual stipulation limiting the creditor's right to pursue in time, the fact that the surety is called upon to pay after the expiry date of their commitment has no bearing on their obligation concerning the debt incurred before that date. The contribution lies in the following sentence: this rule applies even when the suretyship guarantees a specific debt. The argument drawn from the nature of the guaranteed debt, often put forward to claim that a loan suretyship is extinguished with the last installment of the loan, is thus neutralized.

There is an irony in this ruling. The survival of the obligation of payment is usually the creditor's weapon. It serves to pursue the surety years after the apparent end of their commitment. Here, it changes sides. Since the 2010 suretyships were not extinguished, they remained recorded as liabilities of the director. And a heavier liability makes it more difficult for the bank to demonstrate that the surety's assets allowed them to meet their obligation. The rule that extends the surety's commitment therefore protects them in assessing the return to better fortune.

Global indebtedness is calculated on the outstanding balance, not the guaranteed ceiling

The ruling provides a second clarification, more technical and of daily relevance.

The manifest disproportion is assessed with regard to the surety's overall indebtedness, including that resulting from previously undertaken suretyship commitments, provided that these suretyships are not, in whole or in part, extinguished. The wording deserves to be read slowly. What matters is not the expiry date, but the extinction. An expired but unpaid suretyship remains a commitment to be taken into account. Conversely, a paid suretyship, even partially, is excluded from the assessment to the extent of what has been settled.

The amount taken into account is that of the sums remaining due under the principal guaranteed obligation. It is neither the ceiling stipulated in the acte de cautionnement (suretyship agreement), nor the capital initially borrowed. For the surety, the clarification works both ways. It prevents artificially inflating liabilities by adding guarantee ceilings. It also prevents the creditor from reducing a commitment to zero simply because the guaranteed credit has matured, while a balance remains.

The distribution of evidentiary burdens remains unchanged. It is up to the surety invoking legal protection to establish the manifest disproportion of their commitment on the day it was concluded. It is then up to the professional creditor who nonetheless wishes to rely on the suretyship to demonstrate that the surety's assets, at the time they are called upon, allow them to meet their obligation. It is therefore the bank, and not the director, who is responsible for reconstructing the assets on the date of the summons. This clarification dictates the defense strategy.

The litigant's reflex, and what the ruling leaves open

In the banking disputes we handle in Lyon, the first task is now to draw up an exhaustive list of the director's commitments. All commitments, including those believed to be defunct. Suretyships that have expired, avals on financial notes, guarantees given to the benefit of third-party institutions, commitments undertaken for other group companies. For each, the outstanding balance on the date of the summons must be established, with supporting documents: statements, declarations of claim, statements of liabilities from the collective procedure. A forgotten suretyship is a lost argument.

The articulation with the law subsequent to Ordinance no. 2021-1192 of September 15, 2021 requires rigor. For suretyships concluded since January 1, 2022, article 2300 of the Civil Code has replaced the Consumer Code provisions. The sanction is no longer the inability of the creditor to rely on the contract, but the reduction of the suretyship to the amount up to which the surety could commit on the date of its conclusion. The corrective of the return to better fortune has disappeared from the text. The assessment is therefore fixed on the day of signing. But the question of overall indebtedness remains, as it is still necessary to measure what the surety could bear, and their unextinguished prior commitments are included in this calculation.

The ruling does not settle everything. It says nothing about the method of valuing the surety's assets, nor about the treatment of indivis (jointly owned) property or a residence financed by credit. It does not rule on the possible weighting of commitments based on the probability that the guarantee will be called: the outstanding balance is retained, without any apparent risk coefficient. Finally, the cassation (overturning of a lower court decision by the Supreme Court) expressly retains only the May 2010 commitments, leaving it to the referral court to revisit the entire calculation.

For SME directors in Lyon who have accumulated personal guarantees over the course of banking facilities, the decision is an invitation to take nothing for granted. An expired commitment is not an extinguished commitment.

Frequently Asked Questions

Is my suretyship extinguished when the guaranteed loan expires?

No. The expiry terminates your obligation of coverage, meaning the entry of new debts into the scope of the guarantee. It does not affect your obligation to pay already existing debts. The bank can pursue you after this date, within the limits of the limitation period, unless there is an express clause to the contrary limiting its right to pursue.

What exactly is the distinction between the obligation of coverage and the obligation of payment?

The coverage defines which debts your suretyship guarantees and for how long. The payment designates your personal debt to the creditor, arising from the principal debt falling within this scope. The former is extinguished at the agreed term, the latter survives it. It is this dissociation that explains why a 2010 suretyship can still count in 2021.

On what date is the disproportion of my suretyship assessed?

Under the former article L. 341-4 of the Consumer Code, two dates matter. The manifest disproportion is assessed on the day the commitment is concluded. If it is established, the creditor can still act if they demonstrate that your assets, on the day you are called upon, allow you to meet your obligation. In practice, this second day is the day of the summons.

Which commitments must be included in my overall indebtedness?

All those that are not extinguished, in whole or in part. Suretyships that have expired but are not paid are included, including those granted to the benefit of other institutions or for other companies. Avals on financial notes are also included. Only extinction, and not expiry, allows an commitment to be removed from the calculation.

For what amount is a prior suretyship taken into account?

For the sums remaining due under the principal obligation it guarantees. Neither the ceiling in the acte, nor the initial amount of the credit. Therefore, an updated statement must be produced on the date you are called upon, which implies obtaining statements of claims from each concerned institution.

Who bears the burden of proof for the return to better fortune?

The professional creditor. The surety bears the burden of demonstrating the manifest disproportion of their commitment at its conclusion. It is then up to the bank, which nonetheless wishes to rely on the suretyship, to establish that the surety's assets, on the day they are called upon, allow them to meet their obligation. A bank that neglects this demonstration risks having its claim rejected.

Does this solution apply to a suretyship signed after January 1, 2022?

The applicable text is then article 2300 of the Civil Code, resulting from the Ordinance of September 15, 2021. The nature of the sanction changes: the disproportionate suretyship is reduced to the amount up to which the surety could commit, and the return to better fortune is no longer provided for. However, the need to list overall indebtedness, including expired but unextinguished commitments, remains for assessing proportionality on the day of signing.
