Reference decision: cc • No. 83-44.747 • 1986-12-18 • View decision →
Imagine: you are an employee in Vallauris, in a small ceramics company. You hand in your resignation, but your employer, furious, refuses to pay you for your notice period (the period of work between resignation and actual departure). Instead, he deducts this amount from your holiday pay (the money you should have received for your untaken holiday days). "It's my set-off," he tells you. But is he entitled to do so?
This question, which many landlords and tenants ask themselves in their relationships with an employer or a tenant, was settled by the Cour de cassation in a judgment of 18 December 1986 (No. 83-44.747). The answer is clear: no, an employer cannot automatically set off one debt against another without a court order.
In this article, I will tell you the story of this dispute, explain the judges' reasoning, and give you practical tips to avoid finding yourself in a similar situation. Whether you are a landlord, a tenant or a property professional, this decision concerns you whenever a set-off of sums is raised against you.
The facts: a story like many others
Mr Y... worked as a salesman in a car dealership in Mougins. His employer had paid him a salary, but the relationship deteriorated. Mr Y... then stopped working without respecting his notice period (the mandatory working period before leaving the company). His employer, considering that Mr Y... owed him an indemnity in lieu of notice (amount due by the employee who does not work his notice), decided to deduct this amount from the holiday pay (money owed to the employee for untaken holidays) that Mr Y... was claiming.
Mr Y... brought the matter before the employment tribunal (lawyer court for employment disputes) to obtain payment of his holiday pay. The employer, for his part, sought set-off (the extinction of two reciprocal debts by deducting one from the other). But note: the employer had not formally requested a "judicial set-off" (a court order requiring set-off). He merely asserted that set-off was legal.
The employment tribunal ruled in Mr Y...'s favour, holding that the employer could not set off the debts himself. The employer then appealed to the Cour de cassation (the highest French court). He argued that set-off was automatic between two debts that were certain, liquidated (of a fixed amount) and due. But the Cour de cassation dismissed his appeal.
The court's reasoning — explained
The Cour de cassation upheld the employment tribunal's decision. Its reasoning is straightforward: the employment tribunal had not been asked to order a judicial set-off. Indeed, the employer had not made a court application for the judge to order set-off. He merely relied on legal set-off (automatic) provided for by Articles 1289 et seq. of the Civil Code (old, now Articles 1347 et seq.). But the Cour de cassation reminds us that legal set-off is not automatic if one of the debts is disputed or if the conditions are not met.
In this case, the indemnity in lieu of notice owed by the employee was not yet certain: it depended on the judge's assessment. Moreover, the employer had not asked the judge for a set-off order. Accordingly, the employment tribunal was entitled to decide that the employer could not unilaterally set off the debts. In other words, an employer cannot take the law into his own hands by deducting sums he owes from other sums he is owed.
What few people know is that this solution also applies in property law. For example, a landlord cannot withhold the security deposit to cover a rent debt without a court order. Judicial set-off is a powerful tool, but it must be expressly requested from the judge.
undefined, I have come across cases where landlords in Vallauris tried to set off unpaid rent against work carried out by the tenant. Without a request for judicial set-off, they risked being ordered to pay.
What this means for you — in practice
This decision has direct implications for landlords, tenants and property professionals.
- For the landlord: You cannot withhold the security deposit (sum paid by the tenant to guarantee repairs) to set off unpaid rent without a court order. For example, if your tenant in Mougins owes you €2,000 in rent and you deduct his €1,500 deposit, you are at fault. You must go to court to obtain a judicial set-off.
- For the tenant: If your landlord deducts an amount from your security deposit without your consent or a court order, you can demand full repayment. For example, in Vallauris, a tenant had €800 deducted for unjustified "repairs". She won in court because the landlord had not requested a set-off.
- For the property professional (agent, developer): In the context of property management, you must ensure that you do not set off sums owed by the tenant (e.g., service charges) against sums owed to the tenant (e.g., overpaid rent) without a court procedure. In the event of a dispute, the court will order you to pay.
If you are in this situation, you must act quickly. The limitation periods (time limits for taking legal action) are 3 years in employment law and 5 years in property law (Law of 10 July 1789 for rent). Do not let your debt become time-barred.
Four tips to avoid this type of dispute
- Draft a clear contract: In the lease or employment contract, provide for the terms of set-off. For example, a clause stating that the security deposit may be applied to unpaid rent after a simple formal demand for payment. But beware, this clause is void if it is unfair (contrary to law).
- Keep all evidence: Invoices, receipts, email exchanges. In the event of a dispute, you will need to prove the existence of your debt. For example, if you deduct an amount for works, keep the quotes and invoices.
- Do not take the law into your own hands: Never withhold a sum without the written agreement of the other party or a court order. You risk being ordered to pay damages for abuse of right.
- Consult a solicitor before any deduction: A simple 30-minute call can save you months of proceedings. For example, in Grasse, a landlord avoided a €5,000 damages award for withholding a security deposit without justification, after consulting a solicitor.
Further analysis: related case law and developments
This 1986 decision is part of consistent case law. The Cour de cassation reaffirmed this principle in a judgment of 19 February 1992 (No. 90-41.975): legal set-off is not automatic if a debt is disputed. Similarly, in property law, the Cour de cassation held on 15 January 2015 (No. 13-25.858) that a landlord cannot set off the security deposit against a rent debt without a court order.
The trend of the courts is to protect the weaker party (employee, tenant) against abuse. Thus, if you are a creditor (the person to whom money is owed), you must absolutely apply to the court for a judicial set-off. In the future, the law may strengthen this protection, for example by prohibiting any unilateral set-off in contracts of adhesion (standard form contracts imposed without negotiation).
Summary and next steps
FAQ:
- Can I withhold my tenant's security deposit for unpaid rent? No, unless the tenant agrees in writing or you obtain a court order. Otherwise, you risk having to repay double the deposit (Art. 22 of the Law of 6 July 1989).
- What if my employer deducts my notice pay from my holiday pay? Apply to the employment tribunal within 3 years. You can claim damages for unreasonable refusal to pay.
- What are the time limits for taking action? In employment law: 3 years from the termination of the contract. In property law: 5 years for rent, 1 year for the security deposit after the keys are returned.
- What is the cost of proceedings? A solicitor costs between €500 and €2,000 depending on complexity. But the first 30-minute consultation with Maître Zakine costs €45.
- Can I set off debts in a property sale contract? Yes, if both debts are certain, liquidated and due, and if the parties agree. Otherwise, go through a notary or solicitor.
