Personal Guarantees for French SARLs: Rules, Risks, and Practical Protections

Personal guarantees sit at the heart of SME finance in France. Banks and landlords routinely require a director or shareholder of an SARL (société à responsabilité limitée) to “stand behind” the company’s obligations. The legal framework for these undertakings—cautionnements—was significantly clarified by the 15 September 2021 ordinance, which consolidated and modernised disparate rules in the Civil Code with effect from 1 January 2022. This article sets out, in plain but precise terms, what a personal guarantor undertakes, how the courts police disproportionate guarantees, what information creditors must now deliver each year and upon default, how formalities have evolved, and how events such as death, change of corporate form, resignation of the manager, or a merger affect the guarantee. It closes with the core tax consequences for individuals and companies.

The focus is on SARLs because they are the most common private company form in France. The rules described apply broadly to guarantees given by natural persons for professional debts, and to creditors acting in a professional capacity. Throughout, the emphasis is on practical compliance and risk control for managers, shareholders, and creditors.

1. The role of the personal guarantee in SARL finance

In practice, SARL financing frequently hinges on a director or shareholder providing a personal guarantee to secure bank facilities, leases, or supplier credit. Creditors sometimes also require a relative or another shareholder to join as co-guarantor. The guarantee is a separate contract: the guarantor undertakes to pay if the company does not. Its attraction is obvious—credit support without the formalities of real security—so it is ubiquitous in French SME lending and commercial contracting.

The 2021 reform rationalised the law. Rules formerly scattered across the Consumer Code, the Monetary and Financial Code, and the Civil Code now appear in Civil Code articles 2288 to 2320 (and associated provisions), with transitional arrangements for guarantees signed before 1 January 2022. For pre-2022 guarantees, the old regime largely governs, save that the modernised information duties to guarantors (and sub-guarantors) apply from 1 January 2022.

Before going further, a word on the independent first demand guarantee (garantie autonome). This is not a cautionnement. The guarantor’s payment obligation is triggered by the beneficiary’s demand and is, in principle, independent of the underlying debt, save for exceptional defences such as manifest fraud or collusion. Because it is autonomous, it is not subject to the protective rules applicable to personal guarantees. Credit documentation sometimes proposes a “first demand guarantee” when a personal guarantee seemed expected; the legal effects differ materially and should be analysed from the outset.

Finally, if a guarantor is unable to meet the obligation when called, the resulting situation may qualify as personal over-indebtedness. Natural persons—including company directors—can petition the over-indebtedness commission, which may order rescheduling or other relief. This is a last resort but it exists and applies to professional guarantees undertaken by individuals who manage or effectively manage companies.

2. Proportionality: aligning the guarantee with the guarantor’s means

a. Guarantees signed on or after 1 January 2022

The current Civil Code rule is simple in its expression and rigorous in its effect: if, at the date of signature, the guarantee is manifestly disproportionate to the guarantor’s assets and income, the court may reduce the guarantee to the amount for which the guarantor could reasonably have committed. The assessment is made at the time of signature. The sanction is not avoidance of the contract in its entirety; it is a judicial adjustment to a proportionate level.

What does the court look at? It examines the guarantor’s global financial position at signature—income (including regular income derived from the SARL), liquid assets, illiquid property, and existing debt, including earlier guarantees already given. Creditors are expected to ask the prospective guarantor for information about their patrimonial situation; relying solely on the borrower’s credit file is not enough. In litigation, courts may rely on information forms drawn up after the event to evaluate what the guarantor’s situation actually was at signature, but the key moment remains the date the guarantee was given.

Where spouses are concerned, the analysis depends on the matrimonial regime and on whether the common assets were expressly committed. If common assets are engaged, the court considers the couple’s community assets and the spouse’s income. Under separation of property, only the guarantor’s personal assets and income are relevant. Even where common assets are not committed, a valuable community property such as the family home may be taken into account when assessing proportionality, with the understanding that enforcement against non-committed common assets is not possible.

b. Guarantees signed before 1 January 2022

For older guarantees, the prior Consumer Code rule still applies. A professional creditor cannot rely on a personal guarantee if, at signature, the guarantor’s undertaking was manifestly disproportionate to their assets and income, unless the creditor proves that the guarantor’s estate, at the time of being called, allows full payment. In that older regime, the sanction was that the creditor could not rely on the undertaking at all (subject to the “catch-up” proof about the guarantor’s means when called). The burden of proving disproportion at signature lies with the guarantor.

In both regimes, two themes recur. First, expected business upsides do not cure disproportion; the test focuses on existing means, not hoped-for returns from the financed project. Second, shareholder current accounts held by the guarantor in the debtor company may be taken into account as a component of the guarantor’s assets, though liquidity and accessibility will be scrutinised.

3. The creditor’s duty to warn: “informed” and “uninformed” guarantors

The duty to warn is a judge-made and statutory control on creditor conduct. It aims to prevent creditors from taking guarantees from individuals who do not appreciate the risk they assume.

a. Guarantees signed on or after 1 January 2022

The Civil Code now expressly imposes a duty to warn even toward “informed” guarantors, provided the guarantor is a natural person. The sanction has been modernised: for breach of this duty, the creditor is deprived of its rights against the guarantor to the extent of the loss caused by the breach. In practice, courts will ask whether, had a proper warning been given about the borrower’s repayment capacity and the risk of default, the guarantor would have limited or refused the commitment.

b. Guarantees signed before 1 January 2022

Under the older regime, the duty to warn applied only to uninformed guarantors—individuals without the training, experience, or functions indicating a full understanding of the risks. Directors with accounting expertise or extensive financial experience were frequently classed as informed. That said, two important limits persisted: a guarantor—even if informed—could still invoke disproportion, and a creditor could still be faulted for causing an uninformed guarantor to back a debt the borrower self-evidently could not repay.

In short: today, any natural-person guarantor can raise the duty to warn; prior to 2022, only the uninformed could do so. In both periods, proportionality remains its own, separate control.

4. Formalities: the handwritten mention and its evolution

a. The new approach (guarantees from 1 January 2022)

The old formulaic wording has been abandoned. The Civil Code now requires the guarantor to handwrite a personalised mention stating that they commit as guarantor to pay the creditor what the debtor owes in case of default, up to a specified cap (principal and accessories) indicated in figures and in words. The mention is mandatory; the penalty for non-compliance is nullity of the guarantee. The new approach abandons the rigid, pre-printed formula that generated a steady stream of litigation over commas, synonyms, and inadvertent omissions.

Where the guarantee is expressly solidary, the mention must also record that the guarantor recognises they cannot require the creditor to pursue the debtor first or to divide claims among co-guarantors; without this express renunciation in the mention, the guarantor retains those benefits.

b. The older regime (guarantees before 1 January 2022)

Pre-2022, a personal guarantor of a professional creditor had to copy a statutory formula by hand. Seemingly minor departures—substituting “or” for “and,” failing to identify the debtor, or omitting a required term—could nullify the guarantee or limit it (for example, to principal only if interest was omitted). Some benign deviations were tolerated, such as substituting “lender” for “bank,” or clarifying corporate succession. The case law is dense, but its practical legacy is straightforward: if your guarantee predates 2022, expect the wording to be scrutinised minutely.

5. Solidarity: choosing between a simple and a solidary guarantee

A simple guarantee lets the guarantor insist that the creditor first pursue the debtor (benefit of discussion), and in the presence of several guarantors, requires the creditor to divide claims among them (benefit of division). A solidary guarantee removes those shields: the creditor may seek the entirety from any one solidary guarantor and need not sue the debtor first. Creditors almost invariably demand solidarity. From 1 January 2022, the solidarity consequences must be acknowledged in the handwritten mention. For older guarantees, a specific statutory formula was required; absent that formula, the guarantee survives but only as a simple guarantee.

6. Who is a “professional creditor”?

This concept matters because the key protective rules—proportionality controls, duty to warn, annual information, default notices—are directed at professional creditors. The notion is broad: a professional creditor is one whose claim arose in the exercise of its profession or bears a direct link to one of its professional activities, even if that activity is not principal. Banks and finance companies are obvious examples. But so are businesses that extend supplier credit or grant loans connected to their commercial activity. Guarantees given to non-professional creditors are now rare; when they arise, general private-writing rules on evidential formalities apply.

7. Annual information and default notices: the harmonised regime since 2022

a. Annual information

Since 1 January 2022, every professional creditor must, by 31 March each year, inform every natural-person guarantor of the principal, interest, and accessories outstanding as at 31 December of the prior year, and must remind the guarantor of the expiry date of the commitment, or, if of indefinite duration, of the right to terminate at any time and how to do so. This consolidated rule replaces previous overlapping regimes and applies even to guarantees constituted before 2022.

The reform also created a right of information for any sub-guarantor who guarantees the first-rank guarantor. The first-rank guarantor must forward to the sub-guarantor, within a month of receipt, the annual statement and any default notices.

Failing annual information has consequences. Under the prior special banking rule, the sanction was forfeiture of interest accrued between the last compliant notice and the next information event, with more severe consequences in case of fraud or gross fault. Under the new harmonised regime, sanctions align with the Civil Code’s deprivation-of-rights approach, measured to the prejudice.

b. Default notices

As of 1 January 2022, a professional creditor must inform the natural-person guarantor upon the first unpaid instalment or amount not regularised within a month of its due date. The guarantor who intends to pay must notify the debtor beforehand; failing this, the guarantor may lose recourse against the debtor if, when the guarantor paid, the debtor could have had the claim declared extinguished. The sanction applies even if the guarantor pays only after the creditor sues.

Before 2022, similar default-notification duties existed via multiple texts depending on the creditor and the relationship; the reform consolidates and simplifies them.

8. How events affect the guarantee

a. Illness or death of the guarantor

Illness does not discharge a guarantor. Upon death, heirs are not bound for future debts arising after the date of death, but remain bound for debts originating before the death, even if not yet due at that date. Annual information duties thereafter run toward the heirs.

b. Transformation of the debtor company

A change of form that does not create a new legal person (for example, SARL into SA) leaves the guarantee in place unless the contract stipulates otherwise. This flows from the principle that the debtor remains the same legal entity.

c. Resignation or removal of the guarantor-manager

A manager who guaranteed the company’s debts remains bound after ceasing office unless the guarantee was expressly tied to the office and stated that it would terminate automatically upon ending the function. Creditors are under no general duty to inform former managers that their guarantees persist after they step down, particularly where the guarantee is of indefinite duration and revocable only upon notice. If the guarantee covers “all present and future sums,” the former manager may be liable for new facilities drawn before they notified revocation. The cleanest practice is to limit scope and duration in the drafting and, upon exit, to serve a formal revocation in strict accordance with the contract.

d. Mergers and business combinations

The Civil Code now codifies a nuanced rule. Where the debtor company is dissolved via merger, demerger, or universal transfer of assets, the guarantor remains bound for debts that originated before the operation became opposable to third parties. For debts arising after the operation, the guarantor is bound only if they consented at the time to extending the guarantee to those post-operation obligations (or, for debts owed to the creditor company in a merger, had given prior consent).

Two practical corollaries persist from case law. First, where a guarantee backed a loan entered into before the merger, the guarantor remains bound even if the loan was not yet due at merger completion. Second, a merger’s retroactive accounting date agreed between parties does not change the legal analysis; what counts is the formal approval date rendering the merger opposable.

9. Practical drafting and litigation pointers

Scope and cap. Define the cap in principal and accessories; avoid “all sums” formulas unless commercially indispensable. For indefinite-duration guarantees, define a clear revocation mechanism, notice address, and effect on existing exposures (e.g., cap exposure to outstandings on the revocation date and prohibit re-use of facilities).

Solidarity. If solidarity is required, recite it expressly and include the mandatory renunciations in the handwritten mention under the current regime. Where multiple guarantors exist, consider a contribution agreement among them to avoid inequitable burden-sharing.

Financial disclosure and proportionality. Collect a signed financial statement from the guarantor at signature and at renewal. Ask for evidence of income and liabilities. Record that the creditor analysed repayment capacity and delivered a duty-to-warn letter describing the borrower’s risk profile and the foreseeable burden on the guarantor.

Annual information and default notices. Calendar the 31 March deadline and the first-default notifications. Maintain proof of dispatch. For guarantees predating 2022, continue to observe prior banking practices; the new rule applies, but good documentation is still your best defence.

Change of control, resignation, and mergers. Include change-of-control clauses and express terms for resignation of a manager-guarantor. For anticipated mergers, draft a consent clause addressing post-operation debts; the absence of consent is treated against the creditor.

Handwritten mention. Under the present regime, the guarantor must write the core commitment and cap in figures and words. Provide a model with blank spaces for the cap and debtor identity, but do not pre-print what the law requires to be written by hand. Supervise execution carefully.

10. Tax treatment

a. Income tax for the individual guarantor

As a rule, capital repaid by a guarantor in lieu of the debtor is not a deductible expense from the guarantor’s taxable income, nor are interest payments made on the debtor’s behalf. There is, however, a narrow exception for company officers who guaranteed their company’s debts: sums paid under such a guarantee may be deducted if the guarantee was given in the ordinary course of business, is linked to the officer’s functions, and the amount does not exceed three times the officer’s remuneration (or the remuneration reasonably expected when giving the guarantee). The deduction is taken against income received from the company in the same year; any excess may constitute a category deficit imputable to global income under specific rules. The analysis is fact-intensive and should be documented contemporaneously.

b. Corporate income tax for companies paying under a guarantee

Payments made by a company under a guarantee in favour of another company are deductible if they constitute a normal act of management. Gratuitous guarantees to third parties or to a healthy subsidiary often trigger a finding of abnormal management, disallowing deduction. The test is commercial interest: is the guarantee coherent with the guarantor’s own business strategy and advantage, and is the risk proportionate?

11. Checklist for managers and shareholders before signing

1. Quantify the exposure. Fix a cap consistent with personal means. Avoid open-ended “all sums” formulations.

2. Match duration to risk. Prefer fixed terms or, if indefinite, a revocation mechanism and a cap that crystallises at revocation.

3. Verify solidarity. Understand the loss of discussion and division benefits. If co-guaranteeing, negotiate contribution terms with co-guarantors.

4. Provide accurate financial information. Complete the creditor’s information form truthfully; retain copies.

5. Seek the duty-to-warn letter. Ensure the creditor sets out the borrower’s repayment capacity and the risks plainly.

6. Observe formalities. Handwrite the legally required mention; state the cap in words and figures; identify the debtor correctly; include solidarity renunciations where needed.

7. Calendar notices. Note the annual information deadline and ensure address details are current; record any default notices received.

8. Plan for life events. If resigning as manager, revoke the guarantee by formal notice and obtain written acknowledgment. On mergers, require the creditor to confirm the guarantee’s scope going forward or limit it by contract.

12. Conclusion

Personal guarantees remain a central lever of credit support for SARLs. The reform effective 1 January 2022 modernises and simplifies the law without diluting its protective thrust. The proportionality control now calibrates guarantees to the guarantor’s means; the duty to warn applies to all natural-person guarantors; information duties are harmonised annually and upon default; and formalities are clearer, with a functional handwritten mention replacing the trap-laden statutory formula.

For managers and shareholders, the message is consistent: draft deliberately, cap exposure, insist on transparent risk disclosures, and keep contemporaneous records. For creditors, the pathway is equally clear: assess the guarantor’s means, document the warning, meet annual and default information deadlines, and supervise execution of the handwritten mention. In a litigation setting, these disciplines often determine the outcome.

A sound guarantee is not an afterthought to the loan; it is a core instrument that demands the same care as the facility itself. When it is structured proportionately, monitored diligently, and administered lawfully, it serves its purpose: unlocking finance for the SARL while keeping risk within defensible legal limits.
