An invoice has been unpaid for six weeks, the client no longer answers the telephone, and the manager hesitates between chasing payment himself and going straight to court. In most cases, a well-drafted amicable debt recovery letter settles the dispute without proceedings, provided that it contains the right details and prepares the litigation stage. This guide sets out the exact content of an amicable debt recovery letter, provides a template for chasing an unpaid invoice that can be reused directly, and points out the errors that deprive the reminder of any probative value before a court. It finally explains how to move on to a formal notice (mise en demeure) and then, if necessary, to an order for payment (injonction de payer).
Amicable recovery: what exactly are we talking about
Amicable recovery means any step aimed at obtaining payment of a debt without going through a court or a measure of enforcement. It is distinguished from recovery through the courts (order for payment, summons) and from enforced recovery (seizure carried out by a commissaire de justice (bailiff) after obtaining an enforceable title).
Two situations must be distinguished, because they are not governed by the same regime.
A creditor who chases his own debtor himself acts freely. A tradesman claiming the balance of a building job, an accounting firm chasing its fees or a company pursuing a commercial invoice need no particular mandate. They must simply comply with the general rules of the law of obligations and not commit any abuse (threats, harassment).
By contrast, a person who recovers a debt on behalf of another in a professional capacity, a debt collection company for example, is subject to Articles R. 124-1 et seq. of the French Code of Civil Enforcement Procedures. Article R. 124-4 then requires specific details in the first letter sent to the debtor. These requirements provide a good basis for drafting even for a creditor acting alone, because they make the letter clear and enforceable against the debtor. What these companies may demand from the debtor, and what is forbidden to them, is set out in our article on the abusive practices of debt collection companies.
The amicable debt recovery letter therefore comes before any litigation. It pursues a dual objective: obtaining payment quickly, and creating a dated record of the demand, which is essential if the matter later goes to court.
The mandatory and useful details of an amicable recovery letter
An effective reminder is not a mere polite request. It must identify the debt and its basis unambiguously, so as to leave the debtor no argument for a formal challenge.
Drawing on Article R. 124-4 of the French Code of Civil Enforcement Procedures, the letter should contain the following:
- the full identity of the creditor (company name, legal form, registered office, SIREN number (French business registration number) for a business; name and address for an individual)
- the full identity of the debtor to whom it is addressed
- the basis of the debt, that is, the contract, purchase order, signed quotation or invoice that supports it
- a precise statement of the sums claimed, distinguishing the principal, late-payment interest and any costs
- the time allowed for payment and the means of payment (bank details, accepted methods)
- the steps envisaged in the event of non-payment (formal notice, court proceedings)
The statement of account is the point most often neglected. Writing “you owe us €4,200” is not enough. The amounts must be broken down: principal amount of the invoice, late-payment interest calculated from the due date, and the fixed recovery costs allowance where the debt is owed between businesses.
Late-payment interest and the fixed allowance
Between businesses, Article L. 441-10 of the French Commercial Code sets the regime for late-payment penalties. Unless the contract provides otherwise, the applicable rate is the European Central Bank key rate plus ten points, with a floor of three times the legal interest rate. These penalties fall due without any reminder being necessary, from the day after the payment date shown on the invoice. The calculation of these penalties and how they interact with contractual clauses are dealt with separately in our article on Article L. 441-10 of the French Commercial Code.
To this interest is added a fixed allowance for recovery costs, the amount of which is set at €40 by Article D. 441-5 of the French Commercial Code. This allowance is due as of right for each invoice paid late between businesses. Mentioning it in the reminder strengthens its credibility and reminds the debtor of the real cost of the delay.
Where the debt concerns an individual, this regime does not apply. Default interest then runs at the legal rate from the formal notice, in accordance with Article 1344-1 of the French Civil Code, unless the contract provides for a contractual rate.
Template amicable debt recovery letter (reminder of an unpaid invoice)
The template below is suitable for a first firm reminder, which may already operate as a formal notice if it contains the appropriate wording. It is presented for a debt between businesses, to be adapted according to the nature of the debtor. It is sent by registered letter with acknowledgement of receipt, the only method that makes it possible to date the demand and to prove its receipt.
[Creditor's company name, legal form, share capital, registered office, SIREN] [Contact details]
[Debtor's name and address]
Registered letter with acknowledgement of receipt [Town], [date]
Subject: formal notice to pay, invoice No. [•] of [•]
Dear Sir or Madam,
Unless there is an error or omission on our part, our invoice No. [•] issued on [•] for an amount of €[•] including all taxes, corresponding to [nature of the service or delivery, reference of the purchase order or of the quotation signed on •], remains unpaid to date, despite its due date of [•].
We hereby give you formal notice to pay us, within eight days of receipt of this letter, the following sum:
- principal: €[•]
- late-payment interest at the rate of [•] (Article L. 441-10 of the French Commercial Code) accrued since [•]: €[•]
- fixed allowance for recovery costs (Article D. 441-5 of the French Commercial Code): €40
- total due: €[•]
Payment may be made by transfer to the following account: [IBAN].
Failing payment within the stated period, we shall apply to the competent court to obtain judgment against you for payment of this sum, together with interest and the costs of the proceedings, in particular by way of an order for payment.
We remain at your disposal to agree, if appropriate, a written payment schedule.
[Signature, name and capacity of the signatory]
This template for chasing an unpaid invoice combines two functions: it informs the debtor precisely and it constitutes a formal notice within the meaning of Article 1344 of the French Civil Code, which provides that the debtor is put on notice to pay by a summons or by an instrument containing a sufficient demand. The wording “we hereby give you formal notice to pay us, within eight days” meets this requirement of a sufficient demand.
Should one begin with a simple reminder or with a formal notice
For a first delay by a client who is usually solvent, a courteous reminder by email or by ordinary letter is often enough and preserves the commercial relationship. There is no legal obligation to send several reminders before the formal notice. A creditor may go straight to a formal notice by registered letter.
The choice depends on the context: how long the delay has lasted, the amount, the debtor's behaviour, whether there is a dispute. As soon as silence sets in or the debt approaches a limitation period, a formal notice by registered letter is called for without delay.
The errors that cause the reminder to lose its probative value
A badly drafted reminder is not only ineffective: it may weaken the creditor's position before the court. Several errors recur regularly.
Sending an ordinary letter or an email that is not kept
An ordinary letter proves neither dispatch nor receipt. Before the court, the creditor must establish that the debtor was indeed put on notice. A registered letter with acknowledgement of receipt provides a certain date and proof of delivery attempt. An email may have probative value, but it is more fragile and more easily challenged. For the decisive formal notice, registered post remains the benchmark.
Omitting the statement of account or claiming an incorrect amount
A letter that claims an overall sum without a breakdown, or that includes interest calculated from the wrong start date, opens the door to challenge. The debtor may argue that he was unaware of the detail of what was being claimed from him. Worse, an overstated amount may be interpreted as a claim made in bad faith. The statement of account must be accurate, verifiable and supported by the documents (invoice, contract).
Using disproportionate threats
Announcing an immediate seizure when no enforceable title has been obtained, referring to a non-existent banking blacklisting, threatening a criminal complaint for a mere civil debt: such wording exposes the creditor to criticism and discredits the reminder. The only legitimate next step to announce is an application to the civil court. Recovery must not suggest consequences that do not exist.
Believing that a reminder interrupts the limitation period
This is the error with the heaviest consequences. A reminder letter or formal notice, even by registered post, does not interrupt the limitation period. The only acts that interrupt it are exhaustively listed in the French Civil Code: acknowledgement by the debtor of the right of the person against whom he was benefiting from limitation (Article 2240), a claim brought before the court (Article 2241), and a protective measure or an act of enforcement (Article 2244). A creditor who accumulates reminders for months, convinced that he is preserving his rights, may see his claim become time-barred while he waits.
A skilful use of this rule is to obtain from the debtor a document amounting to an acknowledgement of debt, for example an email in which he asks for a payment schedule and acknowledges the amount due. That document interrupts the limitation period and starts a new one running. That is why the template above offers a payment schedule: the debtor's written reply, if it acknowledges the debt, secures the claim.
Failing to keep proof of the basis of the debt
A reminder is worth only as much as the file that supports it. Without a signed quotation, purchase order, delivery note or accepted invoice, the creditor will struggle to show the existence and amount of the debt. Drafting the letter is the right time to check that all the supporting documents are assembled and consistent.
The next step: from formal notice to order for payment
When the formal notice has no effect, the creditor has several routes. The choice depends on the nature of the debt and on the debtor's attitude.
The formal notice
If the first reminder did not amount to a formal notice, a formal notice by registered letter is the last amicable step. It starts default interest running at the legal rate for non-commercial debts, under Article 1344-1 of the French Civil Code, and it marks the limit beyond which the court route will be taken. It usually allows a final period, often of eight to fifteen days.
The order for payment
For a debt that is certain, liquidated and due, that is, one whose existence cannot seriously be disputed, whose amount is determined and whose due date has passed, the order for payment procedure (injonction de payer) provided for by Articles 1405 et seq. of the French Code of Civil Procedure is the most effective. It has several advantages: it is inexpensive, it does not require a hearing at first, and it rests on the judge's examination of the documents.
The application is filed with the commercial court (tribunal de commerce) where the debt is commercial in nature (between traders or commercial companies), and with the judicial court (tribunal judiciaire) in other cases. The judge issues an order for payment, which must then be served on the debtor by a commissaire de justice. The debtor has one month to lodge an objection. If there is no objection, the creditor may have the order endorsed with the enforcement formula, which gives him a title allowing him to have recourse to seizure. The preparation of the file, the filing of the application and the cost of this procedure are set out in our article on the order for payment applied to invoices between businesses.
At this stage, the amicable recovery letter comes into its own: attached to the application, it shows the judge that the creditor first attempted an amicable settlement and that the debtor was duly informed.
The summons on the merits
Where the debt is disputed as to its principle or its amount, an order for payment is not suitable, because the debtor's objection would bring the matter back to adversarial argument. It is then better to issue a summons directly on the merits, with the assistance of a lawyer, so that the dispute is decided. An application for an interim payment in summary proceedings (référé provision) may also be considered where the obligation cannot seriously be disputed and urgency justifies it.
Linking the amicable stage and litigation properly
The amicable debt recovery letter is not an isolated formality. It forms part of a chain: assembling the evidence file, reminder, formal notice, then, failing payment, order for payment or summons. Each link prepares the next. A precise reminder, dated by registered post and supported by an exact statement of account, becomes the key document of the application to the judge. An approximate reminder, sent by ordinary letter and riddled with inaccurate threats, does the creditor a disservice.
The position is clear: a single rigorous letter, amounting to a formal notice within the meaning of Article 1344 of the French Civil Code, is better than a succession of soft reminders that let time slip by without interrupting the limitation period. Before sending a reminder, check the due date of the invoice and the applicable limitation period (five years in principle, Article 2224 of the French Civil Code and Article L. 110-4 of the French Commercial Code between businesses). And if the debtor acknowledges the debt in writing or asks for a payment schedule, keep that document: it is the evidence that alone starts the limitation period running afresh and secures the claim durably.
Frequently asked questions
Does an amicable debt recovery letter interrupt the limitation period?
No. A reminder or formal notice, even by registered post, does not interrupt the limitation period. Only acknowledgement of debt by the debtor (Article 2240 of the French Civil Code), a claim brought before the court (Article 2241) and a measure of enforcement (Article 2244) interrupt that period. A creditor who merely sends reminders for several years risks seeing his claim become time-barred, in principle after five years (Article 2224 of the French Civil Code).
Must the formal notice letter necessarily be sent by registered post?
No provision requires a registered letter for a formal notice to be valid within the meaning of Article 1344 of the French Civil Code: a sufficient demand is enough. In practice, registered post with acknowledgement of receipt remains indispensable, because it proves the date and receipt of the demand. Without that proof, the creditor will struggle to establish before the court that the debtor was indeed put on notice.
Can I claim interest and costs in my reminder?
Yes, within the legal limits. Between businesses, Article L. 441-10 of the French Commercial Code provides for late-payment penalties at the European Central Bank rate plus ten points (unless the contract provides otherwise) and a fixed allowance of €40 per invoice (Article D. 441-5). Against an individual, interest at the legal rate runs from the formal notice (Article 1344-1 of the French Civil Code), unless a contractual rate is provided for in the contract.
What is the difference between a simple reminder and a formal notice?
A simple reminder invites payment without any particular legal effect. A formal notice is a formal act that puts the debtor on notice sufficiently, starts default interest running and marks the starting point of the litigation phase. A letter may amount to a formal notice provided that it uses clear terms of demand and sets a time limit for payment.
Should one go through a debt collection company or a lawyer?
The creditor may chase his debtor himself without an intermediary. A debt collection company acting on behalf of another is subject to Articles R. 124-1 et seq. of the French Code of Civil Enforcement Procedures and to mandatory details. For a debt that is disputed, substantial or close to being time-barred, a lawyer secures the strategy and directly starts the order for payment or the summons.
Which court should be seized if the amicable step fails?
For an order for payment, the application is filed with the commercial court if the debt is commercial in nature, and with the judicial court in other cases, under Articles 1405 et seq. of the French Code of Civil Procedure. The debtor has one month to lodge an objection after service of the order. If the debt is seriously disputed, a summons on the merits or an application for interim payment in summary proceedings is preferable.
How long should an unpaid invoice be left before acting?
One should not wait. A debt between businesses is time-barred in principle after five years (Article L. 110-4 of the French Commercial Code), as are personal actions (Article 2224 of the French Civil Code), but some debts are subject to shorter periods. The earlier the step is taken, the higher the chances of payment and the more solid the evidence file remains. A formal notice sent in the first month of delay is good practice.
