Revision of Service Charge Apportionment: Only Takes Effect from Judgment (Cass. 1972)

Imagine: you own a flat in Tarnos, in the Landes, and for years you have been paying service charges which you consider unfair. On 1 May, the managing agent demands 8,325.79 francs (approximately 1,269 euros) from you in respect of charges and provisions. You refuse, arguing that the apportionment is incorrect. After months of proceedings, the court finds in your favour on 15 December. Good news? Not quite: the revision ordered will only apply for the future, from the date of the judgment. The sums already paid remain with the owners' association. This is what the Court of Cassation clarified in a judgment of 24 October 1972, still applicable today. But what exactly does this change?

The Facts: A Story Like Any Other

Mr X, owner of a unit in a Parisian block of flats held under co-ownership, receives a demand for service charges from the managing agent: 8,325.79 francs, corresponding to his share of the common charges and to provisions. He disputes the amount, considering that the apportionment set out in the co-ownership rules is inequitable, or even contrary to Article 12 of the Law of 10 July 1965 (which requires apportionment according to the objective utility of each unit).

The owners' association sues him for payment. Mr X, for his part, asks the court to revise the apportionment of charges. The Court of Appeal partly finds in his favour: it orders a new apportionment, but specifies that this revision will only have effect for the future, from the date of the judgment. Consequently, Mr X must pay the 8,325.79 francs demanded, with interest at the rate provided for in the co-ownership rules (Article 17).

Mr X appeals to the Court of Cassation. He argues that the revision of the charges should have had retroactive effect from the date the claim was brought. In other words, he considered that the sums due should have been recalculated on the basis of the new apportionment, which would have reduced, or even cancelled, his debt.

This type of dispute is common in medium-sized co-ownership schemes, such as those found in Capbreton or Tarnos. undefined, I have come across cases where a co-owner was allocated 60% of the lift charges even though his unit was on the ground floor… The question of temporal effect is crucial.

The Court's Reasoning — Analysed

The Court of Cassation dismisses Mr X's appeal. It reiterates the principle laid down by Article 12 of the Law of 10 July 1965: 'Where judges proceed to revise the apportionment of the common charges of a building held under co-ownership, such revision only takes effect from the decision ordering it.'

In other words, judicial revision is prospective, not retroactive. Why? Because the law does not provide for retroactive effect in this case, and because legal certainty requires it: co-ownership schemes must be able to rely on predictable budgets. If every challenge called into question charges already collected, management would become impossible.

The Court also specifies that the managing agent may demand payment of unpaid charges and provisions on the basis of the old apportionment, as long as a judgment has not modified it. In this case, Mr X therefore had to pay the sum of 8,325.79 francs, with the interest provided for in Article 17 of the co-ownership rules (generally a statutory rate increased).

However, note that this principle only concerns judicial revision. If the co-owners modify the apportionment by vote at a general meeting (unanimously or by the majority provided for by law), such modification may have retroactive effect if the meeting expressly so decides. But when a judge intervenes, it is only for the future.

What few people know: Article 12 of the 1965 Law was amended by the ALUR Law of 2014, but the principle of non-retroactivity of judicial revision remains unchanged. It has been reaffirmed by the Court of Cassation in several subsequent judgments.

What This Means for You — Practically

For the co-owner challenging their charges: If you bring proceedings to obtain a revision of the apportionment, do not expect a refund of sums already paid. The revision will only apply to future demands for charges, from the date of the judgment. You must therefore continue to pay charges according to the old apportionment until the decision, on pain of proceedings and late payment interest. Concrete example: in Capbreton, an owner of a studio in a residence with a swimming pool was allocated 10% of the maintenance charges for the pool even though he did not use it. He obtained a judicial revision, but could not recover the 2,000 € already paid over three years.

For the owners' association: This case law is protective. It prevents the co-ownership's cash flow from being weakened by retroactive refunds. If a co-owner challenges the apportionment, the managing agent can continue to demand charges on the old basis until a final decision is made. However, he must provision for the risk if the claim appears well-founded.

For the purchaser of a unit: Before buying, check whether an action for revision of charges is pending or whether a recent judgment has modified the apportionment. If a judgment is made after your purchase, you will be affected for the future. If the action is pending, future charges may change, but not arrears.

For the tenant: Rental charges (recoverable) are generally calculated according to the same apportionment keys as the co-ownership charges. If the apportionment is modified, this may affect the amount of the service charge provisions you pay to the landlord. However, this modification only applies from the date of the judgment, unless there is a contractual clause to the contrary.

In short, if you are in a situation of challenge, you must: (1) continue to pay on the old basis to avoid penalties, (2) act quickly in court to limit the period of application of the old apportionment, (3) possibly negotiate an amicable agreement with the owners' association for retroactive application (possible if the general meeting votes a unanimous modification).

Four Tips to Avoid This Type of Dispute

• Check the co-ownership rules upon acquisition: Do not rely on the seller's statements. Have a professional analyse the apportionment keys for charges (tantièmes) to detect any inconsistencies. In Tarnos, an owner discovered that his garage was counted with 30 tantièmes of lift charges even though it was on the ground floor.
• Challenge promptly at the general meeting: Before going to court, raise the issue at a general meeting. An amicable modification is faster and can be retroactive, unlike judicial revision.
• Do not stop paying while awaiting judgment: As the judgment illustrates, the managing agent can claim the sums due on the old basis, with interest. If you stop paying, you risk proceedings and additional costs.
• Keep all supporting documents: Demands for charges, minutes of general meetings, co-ownership rules, correspondence. In the event of a dispute, these documents are essential to demonstrate the inequity of the apportionment.

The Court of Cassation has confirmed this principle on several occasions. For example, in a judgment of 16 December 2009 (n° 08-19.369), it held that the revision of charges ordered by the judge cannot take effect before the judgment, even if the claim had been brought several years earlier. Similarly, the judgment of 24 October 1972 is often cited as the foundation of the rule.

This principle is consistent with the concept of the 'relative effect of judicial decisions': a judgment cannot call into question definitive legal situations (charges already paid and accepted). This provides security for co-ownership schemes.

However, case law has evolved on one point: since the ALUR Law of 2014, the judge can now, at the request of a co-owner, revise the apportionment of charges if it is manifestly abusive or contrary to the allocation of the units. But the effect remains prospective. The tendency of the courts is therefore to favour the financial stability of co-ownership schemes, even if the aggrieved co-owners cannot recover the sums already paid.

In Practice: What to Do

FAQ:

Can I claim a refund of overpaid charges if I obtain a judicial revision? No, the revision only has effect for the future. Overpayments before the judgment are not refundable, unless you can prove a calculation error or fraud.

What should I do if I discover an inequity in the apportionment of charges? Gather the evidence, request mediation or a modification at a general meeting. If no agreement is possible, bring proceedings before the tribunal judiciaire. But do not stop paying in the meantime.

What are the time limits for bringing an action for revision of charges? The action is time-barred after 5 years from the discovery of the inequity (and at the latest 20 years after the allocation). But the sooner you act, the less you will suffer under the old apportionment.

Can the managing agent impose interest on unpaid charges? Yes, if the co-ownership rules so provide (Article 17). Generally, a contractual interest rate is set (e.g., 1% per month). Without a clause, interest at the statutory rate applies.

Can I challenge the revision before the Court of Appeal? Yes, but the appeal does not suspend enforcement. You must pay the charges according to the first instance decision until the appeal judgment.
