Picture a British investor with a small flat in the 11ᵉ arrondissement of Paris. He’s away in Greece for the summer, the flat is let to a tenant, and the syndic of the building holds the annual general meeting (the assemblée générale) without him. A few days later, a French postman comes to the Paris flat with a lettre recommandée avec accusé de réception — the registered letter that contains the AGM minutes. Nobody is home. The post office leaves the standard slip and holds the letter for fifteen days. The investor doesn’t pick it up. The letter is returned to the syndic. Late September, back from holiday, our investor opens his French mail and finds an unhappy surprise: the AGM voted through a major insulation project that will cost his share around €11,000, plus a syndic-mandate change he would have voted against. He calls his French avocat. The avocat asks him when the registered letter was first presented. About six weeks ago. The avocat winces. The two-month window to contest those decisions is already most of the way through, and might in fact already be closed. On 16 April 2026, the Cour de Cassation — France’s supreme court for civil matters — confirmed, with unusual care, that this is exactly how the rule works.
The ruling (Civ. 3e, 16 avril 2026, n° 24-18.842, FS-B, marked for publication at the Bulletin) settles two questions in one short, well-reasoned arrêt. First, that the two-month deadline to contest a French copropriété AGM decision runs from the day after the first presentation of the registered letter at the recipient’s address — irrespective of whether the recipient ever actually retrieves it. Second, that this rule is compliant with article 6 §1 of the European Convention on Human Rights, the right to a fair trial. Neither point is brand-new in French case law, but the 16 April 2026 ruling is the clearest, most fully reasoned articulation to date — and it is now the leading authority on both. For British investors who own a flat in a French copropriété (which is most British buyers in Paris, the Côte d’Azur, the Alps, and the regional cities), this is the kind of procedural rule it pays to know cold. For the broader procedural map of recent French Cour de Cassation rulings affecting British buyers, our notarial-deed rectification article covers the sister-ruling from the same court the same day, and our bail à vie auction-trap article covers the long-dated 2010 case on lease clauses that survive a sale.
What the 16 April 2026 ruling decided
The legal hook is short and clean. A copropriétaire who voted against a decision — or who failed to attend the AGM at all (a défaillant) — has the right to contest those decisions in court. Article 42 of the loi du 10 juillet 1965 (the foundational French copropriété statute) gives them two months to do so, on pain of déchéance — i.e. the action is barred. The two months run from “the notification of the procès-verbal of the assembly”. The procedural framework — set out in article 18 of the décret du 17 mars 1967 for the syndic’s obligation to notify the procès-verbal to opposants and défaillants, and in article 64 of the same décret for the registered-letter mechanic itself — confirms the same. Article 64 is the operative provision: it provides expressly that, when notification is made by registered letter, “the deadline runs from the day following the first presentation of the registered letter at the recipient’s home”. That is the article on which both the 2023 ruling and the 16 April 2026 ruling anchor their reasoning.
What the law does not spell out, in so many words, is what happens if the registered letter is sent but never retrieved. Two readings were available. The first: the deadline only runs once the recipient has actually received the letter, on the basis that there is no real “notification” of something the recipient has not yet seen. The second: the deadline runs from the day after the postman first attempts to deliver the letter at the address, whether the recipient is home or not. The Cour de Cassation has repeatedly preferred the second reading — in a 2007 ruling (Civ. 3ᵉ, 20 juin 2007, n° 06-13.641) and again in a 2023 ruling (Civ. 3ᵉ, 29 juin 2023, n° 21-21.708) — but the rule was not always applied consistently in the lower courts. The 16 April 2026 ruling is the latest, clearest re-confirmation, and now stands as the leading authority.
The court’s reasoning, in plain English, is that the loi of 1965 makes no distinction between a registered letter that is retrieved and one that is not. There is no statutory hook for a “didn’t pick it up” carve-out. The clock starts on the day after the first presentation at the recipient’s address, full stop. Whether the recipient is home, whether they retrieve the letter from the post office during the standard 15-day collection window, whether they ever read the procès-verbal at all — none of that affects when the two-month deadline starts running.
Why the rule is so short — and so unforgiving
Two months from first presentation is, by any measure, a tight window. For a French resident copropriétaire who picks up their post promptly, two months is plenty of time to read the procès-verbal, talk to an avocat, and decide whether to contest. For a non-resident landlord whose mail accumulates while they are abroad, or whose registered French address has not been updated, the practical window can be substantially shorter — sometimes only a few weeks, occasionally already expired by the time the issue is even noticed.
The court’s policy reasoning for keeping the rule short is straightforward: French copropriétés need legal certainty about which AGM decisions are final. A decision to commission a major energy-renovation project, to change syndic, to approve the annual budget — these need to be relied upon by contractors, banks, lenders, prospective buyers, and the syndicate itself. If a copropriétaire could quietly leave a registered letter unclaimed at the post office and then, six months or a year later, surface a contestation argument, the entire commercial machinery of the building would seize up. Article 42 of the 1965 law itself recognises this: it suspends the syndic’s execution of works decided at the AGM during the same two-month window, so that any contestation can be raised before the works actually start. A longer contestation window would mean either suspending the works for longer (delaying the renovation) or executing them and risking the project being unwound months in. Neither outcome is workable.
There is also a complementary point that benefits both sides: a short deadline lets the syndicate cure a procedural irregularity before it becomes a real problem. If a copropriétaire flags a defect in the AGM convocation, for example, the syndicate can convene a fresh AGM and re-vote the disputed decision before the syndic mandate expires or the contractor begins work. A two-month window forces the issue early, while it is still cheap to fix.
Why the rule is also compliant with the European Convention
The argument was raised — perhaps a little hopefully — that a deadline running from a registered-letter presentation that the copropriétaire might never have received cannot be reconciled with article 6 §1 of the European Convention on Human Rights, which guarantees access to a tribunal. The Cour de Cassation had already addressed the point in its 2023 ruling, but the 2026 arrêt is more pedagogical and lays out a clean four-step proportionality analysis worth understanding in full.
(1) The rule is clear and predictable. The text of article 42 and article 18 of the 1967 décret leaves no room for interpretive surprise. A copropriétaire reading either provision could not reasonably believe that the deadline only runs once they have personally retrieved the registered letter.
(2) It does not strike at the substance of the right of access to a tribunal. A French registered letter is held at the post office for 15 days after the first delivery attempt. A copropriétaire who picks up the letter during that 15-day window still has a substantial remaining portion of the two-month deadline in which to act — typically around six weeks. That is not a window that is unreasonably narrow; in most jurisdictions it would be considered generous for a contractual contestation.
(3) It pursues a legitimate aim. Legal certainty in the management of copropriétés, and the orderly execution of collective decisions, are aims that any court would recognise. The aim is not abstract: it directly affects whether contractors get paid for work commissioned by the syndic, whether banks lend against the renovated value of the building, and whether buyers can rely on the AGM minutes when buying or selling a unit.
(4) The means are proportionate to the end. The court explicitly weighs the marginal restriction on the right of access (a two-month window from first presentation rather than from actual receipt) against the marginal gain in legal certainty (no more open-ended uncertainty for the copropriété), and finds the former proportionate to the latter. There is, the court says, a reasonable relationship between the procedural means employed and the goal pursued.
The 16 April 2026 ruling does not break new ground on the ECHR-compliance point — the 2023 ruling had already reached the same conclusion — but the four-step articulation is now the cleanest precedent the lower courts have to work from. If a copropriétaire ever again tries to argue that they were “denied access to a tribunal” because their registered letter sat unclaimed at La Poste, this is the ruling that will be cited against them.
Where this fits in the wider French property timetable
For a British landlord juggling a French rental, French copropriété membership, and (if buying or selling) a French notaire deed, the question of “what’s my deadline, and when does the clock start?” comes up across multiple procedural domains. The table below sets out the main contestation / response windows in one place, with the recent 2026 Cour de Cassation rulings in context.
| Action / event | Deadline | Clock starts from |
|---|---|---|
| Contest a copropriété AGM decision | 2 months | The day after first presentation of the registered letter (NOT receipt). Civ. 3e, 16 avril 2026, n° 24-18.842. |
| Apply the IRL rent revision on a residential lease | 12 months | Lease anniversary date. Article 17-1 loi 89-462. Use-it-or-lose-it. See our IRL Q1 2026 guide. |
| Rectify an error in a notarial sale deed | 5 years | Date of signature of the deed. Civ. 3e, 16 avril 2026, n° 24-22.365. See our notarial-deed rectification article. |
| Vacate the property after landlord’s congé pour reprise | 6 months for unfurnished / 3 months for furnished | Date of receipt of the notice. Article 15 loi 89-462 (unfurnished); article 25-8 (furnished). The figure is the landlord’s notice period — i.e. the tenant’s window to find new housing before the lease ends. |
| Standard civil-liability or contract claim | 5 years | The day the right-holder knew or should have known the facts allowing them to act. Article 2224 Code civil. |
What the table makes visible is how exposed a non-resident landlord is to the AGM contestation rule specifically: the 2-month window is shorter than every other deadline in the table, and it is the only one that runs from a postal-delivery event the recipient may never see. Rectifying a notarial deed gives you five years; revising rent gives you twelve months; even a tenant facing an eviction notice gets six months from actual receipt. The AGM contestation rule is the tightest, the most procedural, and the easiest to miss.
What this means for British investors with property in France
Five practical implications for a non-resident copropriétaire.
Make sure your address with the syndic is correct and active. The syndic notifies the AGM minutes by registered letter to the address you have given them. If that address is a Paris flat you let out, the registered letter will be presented there — not to wherever you actually are. Updating the syndic’s records to a UK address (or to a French notaire’s office, or to a property manager who reliably handles registered letters on your behalf) means the registered letter at least arrives somewhere it will be opened.
Consider giving the syndic a French representative. Many British landlords use a French mandataire — a property manager or a specialist administrator — who handles syndic correspondence on their behalf and can pick up registered letters within the 15-day window. The cost is modest (a few hundred euros a year for a small portfolio) compared to the cost of missing a 2-month contestation deadline on a five-figure decision.
Track AGM dates in a calendar. Most French copropriétés hold the AGM at roughly the same time each year. If you know your AGM is typically held in June, you should be on alert in July and August for the registered letter that contains the procès-verbal. Setting a recurring calendar reminder a month before the typical AGM date — and flagging the following two months — costs nothing and keeps the deadline in view.
If you cannot attend the AGM in person, attend by proxy. French copropriétés allow voting by proxy (pouvoir). Sending a written proxy to a fellow copropriétaire, the syndic, or a French representative, with clear voting instructions on the agenda items, is the cheapest insurance against being recorded as défaillant in the first place. A copropriétaire who voted (even by proxy) has fewer grounds to contest than one who simply did not attend, but the procedural protections are similar — and a represented copropriétaire is usually more engaged with the agenda in the first place.
If you find a registered letter at La Poste, retrieve it within the 15-day window. Once retrieved, you have the remainder of the two-month deadline to act — typically around six weeks. That is enough time to read the procès-verbal, talk to a French avocat, and either decide there is nothing to contest or file a contestation in time. Six weeks evaporates fast when you have to find an avocat in August: start the conversation the day you retrieve the letter.
What if the deadline has already passed
If the two months are gone, the contestation route under article 42 is closed. The 16 April 2026 ruling makes that point explicitly and removes any residual ECHR-based argument for an extension.
What remains, depending on the facts, is a narrower set of fallback options. Where the AGM decision was procedurally void ab initio (for example, where the convocation itself was defective in a way that goes to the substance of the meeting rather than to the notification of its decisions), separate actions for nullity may still be available outside the article-42 window — though these are slow, expensive, and the burden of proof is high. Where the syndic acted on the AGM decision in a way that went beyond what the AGM authorised, an action against the syndic personally may be available. None of these is a clean substitute for a timely contestation. The only reliable answer is to make sure the two-month window is never missed in the first place.
Frequently asked questions
How long do I have to contest a French copropriété AGM decision?
Two months from the day after the first presentation of the registered letter that contains the AGM minutes (the procès-verbal). The starting point is the postal delivery attempt, not your actual receipt of the letter. The Cour de Cassation confirmed this on 16 April 2026 (n° 24-18.842) and held the rule compliant with article 6 §1 of the European Convention on Human Rights.
Does the clock start when I actually pick up the letter, or when the postman first knocks?
When the postman first attempts delivery at your registered address — and specifically the day after that. If you don’t pick the letter up at La Poste during the standard 15-day collection window, the clock keeps running anyway. The Cour de Cassation has been explicit: the rule does not distinguish between letters that are retrieved and letters that are not.
I’m a non-resident landlord and the registered letter went to the rented flat. What can I do?
Update your address with the syndic to one where you can reliably retrieve registered post — most often a UK home address (with international forwarding for recommandés), or the office of a French mandataire (property manager) who handles correspondence on your behalf. Going forward, you will receive AGM notifications and procès-verbaux at an address you actually monitor.
What happens if I miss the 2-month window?
The contestation action under article 42 of the 1965 law is barred (déchéance). Narrower fallback routes may exist where the AGM was procedurally void ab initio, or where the syndic acted beyond the AGM mandate, but none is a clean substitute. The 16 April 2026 ruling forecloses any ECHR-based argument for extending the window.
Why does French law treat first presentation as the trigger?
To preserve legal certainty in the management of copropriétés. If the deadline ran only from actual retrieval, a copropriétaire could indefinitely delay the start of the clock simply by not picking up registered letters. That would block the syndic from reliably executing AGM decisions, delay works (which are already suspended for the two-month period), and create downstream uncertainty for contractors, banks, and other contracting parties. The Cour de Cassation explicitly relies on this rationale.
Does this ruling apply only to AGM decisions or to other copropriété notifications?
The 16 April 2026 ruling specifically addresses the article-42 contestation deadline for AGM decisions. The general principle — that a registered-letter notification triggers a deadline from first presentation, not from actual retrieval — is broader and applies in many other procedural contexts. But the precise reasoning of this ruling is anchored on the copropriété regime.
What if I voted FOR the decision at the AGM and now want to contest it anyway?
You cannot. Article 42 reserves the contestation right to copropriétaires who voted against the decision (opposants) or who failed to attend (défaillants). A copropriétaire who voted for the decision has, by their vote, given consent and is bound by the outcome.
Does this affect the suspension of works decided at the AGM?
No. Article 42 of the 1965 law separately suspends the syndic’s execution of works decided under articles 25 and 26 of the law during the same two-month period (with an urgency exception). That suspension exists to give the contestation window time to run. The 16 April 2026 ruling does not change the suspension framework — it only confirms when the contestation clock starts.
