Lending money to a relative or granting a payment extension to a client engages trust. When memory fails and the relationship sours, the question ceases to be moral and becomes judicial: who owes what, how much, and since when? The acknowledgement of debt (reconnaissance de dette) is the law’s answer to this fragility. A unilateral instrument by which a debtor acknowledges in writing that they owe a specified sum to an identified creditor, it does not create the obligation but proves it – a central distinction that commands most of the litigation we encounter at the firm. Before drafting or challenging such an instrument, one must understand what it truly is, what Article 1376 of the Civil Code requires of it, and how the Cour de cassation has refined its contours since the Act of 13 March 2000.
A unilateral instrument with an evidential function
The acknowledgement of debt is a unilateral legal act: only the debtor’s signature is required. The creditor undertakes no reciprocal obligation. This asymmetry distinguishes it radically from a loan agreement, which is bilateral and obliges the lender to disburse the funds while obliging the borrower to return them. In the acknowledgement, the disbursement is already performed – or presumed to be – at the moment of signature; what remains is the repayment, and the instrument’s sole function is to establish proof.
This evidential nature has a decisive consequence: the absence of an acknowledgement does not prevent the creditor from bringing proceedings – it complicates proof. Article 1353 of the Civil Code provides that “whoever claims performance of an obligation must prove it.” Where the sum exceeds a threshold, Article 1359 requires that proof take the form of a written instrument. The acknowledgement is precisely that instrument. Without it, the creditor remains free to demonstrate the debt by other means – bank transfers, messages, testimony – but with a heavier evidential burden, often insurmountable where the parties are close and payments were made in cash.
When to draft one: the EUR 1,500 threshold
Article 1359 of the Civil Code, read with the implementing decree, sets at EUR 1,500 the threshold above which a legal act must be proved in writing. Below it, proof is free. Above it, writing becomes the rule, and an acknowledgement of debt becomes virtually indispensable – not for the debt’s validity, which exists without it, but for its demonstration in court.
This threshold also governs the need for a tax declaration. Above EUR 5,000 lent, Article 242 ter of the General Tax Code requires the lender to declare the transaction to the tax authorities via form CERFA 2062. The obligation falls on the creditor; its omission does not invalidate the acknowledgement but exposes the lender to a tax fine and weakens the transaction’s credibility.
Conditions of validity: what Article 1376 actually requires
Since the Ordinance of 10 February 2016 reforming the law of obligations, the acknowledgement of debt is governed by Article 1376 of the Civil Code (formerly Article 1326).
Article 1376 of the Civil Code
“A private instrument by which one party alone undertakes to pay a sum of money or deliver fungible property to another constitutes proof only if it bears the signature of the person subscribing the undertaking together with the statement, written by that person, of the sum or quantity in words and in figures. In case of discrepancy, the instrument constitutes proof for the sum written in words.”
Three requirements follow: the debtor’s signature, the sum stated in words, and the sum stated in figures – the latter two written by the debtor personally. Case law has patiently constructed the regime for their absence.
The handwritten statement and its jurisprudential relaxation
Since the Act of 13 March 2000 adapting the law of evidence to information technologies, and confirmed by the Cour de cassation on 28 October 2015 (No. 14-23.110), the statement need not necessarily be handwritten: it may result from an electronic identification process. A typed and electronically signed acknowledgement is valid, provided the process reliably identifies the debtor.
The Cour de cassation has also softened the consequences of an incomplete statement. Since 18 September 2002 (No. 99-13.192): the omission of the figure in digits does not deprive the instrument of its evidential force if the sum in words is present. Conversely, the sum in digits alone, without words, degrades the instrument to a commencement of proof in writing – requiring supplementation by extrinsic evidence.
Commencement of proof in writing: the fallback
An acknowledgement that does not meet all requirements of Article 1376 is not destroyed: it is downgraded to a commencement of proof in writing under Article 1362. The creditor must then supplement it with extrinsic elements – testimony, presumptions, correspondence – to convince the court. The path is narrow but open.
Private instrument or notarial deed: choosing correctly
The acknowledgement may take two forms:
| Criterion | Private instrument | Notarial deed |
|---|---|---|
| Cost | Free (excluding registration) | Proportional notarial fees |
| Certain date | Not enforceable against third parties without registration | Yes, automatically |
| Evidential force | Written evidence if Art. 1376 complied with | Until proved false (inscription de faux) |
| Enforcement title | No – court judgment required | Yes – direct enforcement |
| Time to enforcement on default | Several months (court proceedings) | A few weeks (direct seizure) |
For acknowledgements exceeding EUR 15,000, and a fortiori where the debtor presents a risk of default, the notarial deed is almost always the most efficient option: its cost is recovered the moment it avoids payment order proceedings.
Pitfalls to avoid
Warning – Backdating is a criminal offence
Writing a date earlier than the actual signature date on the instrument constitutes forgery in a private document under Article 441-1 of the Penal Code, punishable by three years’ imprisonment and a EUR 45,000 fine. The legitimate route to establishing a certain date is registration with the tax authorities or deposit with a notary.
Other common pitfalls: omitting the drafting date (complicating limitation calculations); discrepancy between words and figures (resolved by Article 1376 in favour of words); interest rate stipulated orally (without written form, reduced to the statutory rate under Article 1907 of the Civil Code, and subject to the usury ceiling); absence of a due date (making the debt payable on demand, potentially starting limitation from the date of signature).
Limitation: five years, not ten
Since the Act of 17 June 2008 reforming limitation in civil matters, the ordinary limitation period is five years. Article 2224 of the Civil Code provides that “personal or movable actions are time-barred after five years from the day on which the holder of a right knew or should have known the facts enabling them to exercise it.” The action for payment based on an acknowledgement of debt is a personal action: it falls within this period, whether the instrument is private or notarial.
The starting point is the due date of the debt. If the acknowledgement fixes a repayment date, the period runs from that date. If it does not, the creditor may serve formal notice at any time, and the period runs from that notice.
The five-year period may be interrupted by several events, foremost among which is the debtor’s own acknowledgement of the debt (Article 2240 of the Civil Code). Any partial payment, any written confirmation of the debt, any request for time may constitute an interrupting acknowledgement, provided it is unequivocal.
Recovery of an unpaid acknowledgement of debt
When the debtor does not repay at the due date, recovery follows a progression:
- Amicable recovery: reminder, then formal notice by registered letter. The formal notice also starts default interest at the statutory rate (Art. 1231-6 C. civ.).
- Payment order: a non-adversarial procedure (Articles 1405 et seq. CPC). Rapid, inexpensive, suited to claims that are not seriously contestable.
- Obtaining an enforcement title: if unopposed, the order becomes enforceable. If the debt is contested, the creditor must bring proceedings on the merits. Notarial acknowledgements skip this step: they are directly enforceable.
- Forced execution: the enforcement officer (commissaire de justice) implements the appropriate measures: attachment of bank accounts, wage garnishment, seizure-sale of moveables, or even property seizure for substantial claims.
Challenging an acknowledgement of debt: the debtor’s defences
The debtor pursued on the basis of an acknowledgement is not defenceless. Defences fall into two categories: those attacking the instrument’s validity, and those attacking the creditor’s action.
On validity: vitiated consent (error, fraud, duress), lack of capacity (minor, protected adult), failure to comply with Article 1376 (which downgrades the instrument but does not nullify it), and unlawful cause (a gambling debt, a sum owed for an illegal service).
On the action: acquired limitation is the most effective defence where available and must be raised at the earliest stage. The debtor may also argue that the debt has been extinguished by payment – the burden of proving payment then falls on them. Set-off against a reciprocal debt and release of debt are further available defences.
