Compensation of Connected Debts: The Judge Cannot Deny It

Imagine: you own an apartment in Poissy. You rent it to a tradesman who, in exchange for work you have carried out, owes you €5,000 in rent. But you also owe him €3,000 for badly done repairs. Logical to set off, right? Yet, if the debt for repairs is not yet liquidated (exact amount not fixed) or due (not yet payable), some judges might refuse. The decision of 30 March 1989 by the Court of Cassation settles the matter: when debts are connected (arising from the same contract or related transactions), compensation must be allowed, even if one is not liquidated or due. What should you take away from this?

The Facts: A Story Like Many Others

We are in the 1980s, in Nice. A SCI, Gambetta-Park, entrusts construction work to a SNC. To finance the project, the SNC assigns to the Banque niçoise de crédit (BNC) part of its claim against the SCI. Simultaneously, the BNC substitutes itself for the company Herrera-Lopez to pay for the concrete supplies already delivered. So far, everything seems clear. But the accounts become tangled. The BNC demands payment from the SCI, which raises compensation with its own claim, arising from the same project. Problem: the SCI's claim was neither liquidated (exact amount undetermined) nor due (not yet payable). The Court of Appeal of Aix-en-Provence, in 1986, denies compensation. The BNC wins. The SCI appeals to the Court of Cassation.

The Reasoning of the Court — Analysed

The Court of Cassation quashes the Aix-en-Provence decision. It recalls Article 1291 of the Civil Code (in its version then in force, now restated in Articles 1347 et seq.): legal compensation requires liquidated and due debts, except in cases of exception. But it adds a fundamental principle: when debts are connected, the judge cannot deny a request for compensation solely because one is not liquidated or due. What is a connected debt? It is a debt arising from the same legal relationship or from economically linked transactions. Here, the two claims (payment for work by the SCI / payment for concrete supplies by the BNC) arose from the same construction project. They were therefore connected. The Court states that connection overrides the requirement of liquidity and enforceability. In other words, if your debts are linked, you can demand compensation even if one is not yet quantified or due. This is a landmark decision protecting contractual balance.

What This Means for You — Practically

Let us take concrete examples. Landlord in Viroflay: your tenant owes you €2,000 in unpaid rent. You owe him €1,500 for renovation work you commissioned but which was poorly executed. The debt for the work is not yet liquidated (the exact amount is disputed). Thanks to this case law, you can raise compensation in court, even if the amount of the work is not fixed. The judge must allow it, provided you prove the connection (same lease, same premises). Purchaser of a property: you buy a house in Poissy. The seller owes you €10,000 for hidden defects, but you still owe €5,000 of the purchase price. The two debts are connected (single sale). You can set them off. Co-owner: your management company demands €500 in service charges. You claim €300 for works voted but not carried out. Compensation is possible. Caution: compensation is not automatic. You must request it from the judge (or notify it by registered letter). If you do not raise it, the judge will not order it of their own motion.

Four Tips to Avoid This Type of Dispute

• Draft comprehensive contracts: in any contract (lease, sale, works contract), include a compensation clause. Example: "The parties agree that all reciprocal debts arising from this contract may be set off, even if one of them is not liquidated or due." This avoids any contestation.
• Keep all supporting documents: invoices, estimates, correspondence, statements. Connection is proved by documents. If you cannot demonstrate the link between the two debts, compensation will be refused.
• Act without delay: if you owe money to your debtor, do not wait for them to sue you for payment. Raise compensation by registered letter with acknowledgement of receipt, or in your court submissions. Limitation periods (5 years in contractual matters) run.
• Consult a lawyer before raising compensation: a miscalculation may cause you to lose rights. For example, if the opposing debt is time-barred, compensation is no longer possible. A lawyer will verify the conditions.

Further Reading: Related Case Law and Developments

The 1989 decision follows a consistent line. Already in 1975 (Civ. 1re, 4 March 1975), the Court of Cassation had held that connection allows the requirement of enforceability to be disregarded. More recently, the 2016 reform of the law of obligations (Ordonnance n°2016-131) codified legal compensation in Articles 1347 et seq. Article 1347-2 restates the rule: "Compensation may be ordered by the judge in cases of connection, even if one of the debts is not liquidated or due." The trend is therefore towards maintaining and clarifying this principle. This means that, for real estate professionals, compensation is a powerful tool for settling complex accounts, especially in co-ownerships or construction projects.

Checklist Before Acting

• Have I identified two reciprocal debts? Yes/No. If not, compensation is not possible.
• Are they connected? Same contract or economically linked transactions? Example: a lease and works in the leased premises.
• Do I have written evidence? Contracts, invoices, receipts, correspondence.
• Have I notified the compensation? By registered letter or in court. Without notification, compensation does not operate automatically.
• Have I respected the time limits? Five-year limitation period for contractual matters (Art. 2224 C. civ.). Check that your claims are not time-barred.
