You own an apartment in Paris, a villa on the Riviera or a farmhouse converted into three flats, and once a year a letter arrives from a syndic (the managing agent who runs the building) with the minutes of the assemblée générale (the general meeting of co-owners). Most foreign owners file it away. That reflex can cost them dearly. In April 2026 the highest French civil court confirmed a rule of brutal simplicity: the two-month deadline for challenging a co-ownership meeting decision starts running the day after the postman first presents the registered letter at your home, even if you never collect it, even if you were abroad, even if you read the minutes weeks later. Miss that deadline and the decision becomes untouchable, however irregular it was. This guide explains, for foreign owners and their advisers, who is allowed to sue, when the clock really starts, on which grounds a resolution can be annulled, and what happens if nobody acts in time. It describes mechanisms and traps; it does not replace advice on your own file.
French co-ownership law is contained mainly in the Law of 10 July 1965 on the status of co-owned buildings and its implementing Decree of 17 March 1967. Every owner of a flat in a French copropriété (co-ownership) belongs automatically to the syndicat des copropriétaires (the body of co-owners, which has legal personality), votes at the yearly meeting, and pays a share of the collective charges. The meeting decides by majority vote on works, budgets, the choice of managing agent and the authorisation of private works affecting common areas. Because these decisions bind even owners who disagreed, the law gives dissenters a short, sharp remedy: a court action for annulment within two months. The remedy is effective, but it is fenced with forfeiture rules that forgive no one, and recent case law has just made the fence higher.
I. A two-month guillotine: who may challenge, and when the clock starts
The action for annulment is not open to everyone, and it is not open for long. Article 42, second paragraph, of the Law of 10 July 1965 provides that actions contesting general meeting decisions must, on pain of forfeiture, be brought by dissenting or absent co-owners within two months of notification of the meeting minutes, served by the managing agent. The Third Civil Chamber of the Cour de cassation (the highest French court for civil cases) recalled the text in its ruling of 16 April 2026 (appeal no. 24-18.842): « les actions en contestation des décisions des assemblées générales doivent, à peine de déchéance, être introduites par les copropriétaires opposants ou défaillants dans un délai de deux mois à compter de la notification du procès-verbal d’assemblée. » In English, challenges must, on pain of loss of the right to sue, be filed by co-owners who voted against or who were absent, within two months of notification of the minutes. Every word of that sentence matters, starting with who is allowed through the door.
A. Only dissenters and absentees may sue, resolution by resolution
Standing belongs exclusively to the opposant (the co-owner who voted against the resolution) and the défaillant (the co-owner who was absent and unrepresented when the resolution was put to the vote). A co-owner who voted in favour of a resolution, or who abstained, cannot later ask a court to annul it. The quality of dissenter is assessed resolution by resolution, not meeting by meeting: an owner who voted against the vote on facade works but in favour of the vote on the lift contract can challenge the first resolution but not the second. An owner who was absent for the whole meeting can challenge any resolution, while an owner who arrived late can challenge only the resolutions voted before arrival. The practical consequence for a foreign owner is immediate. If you attend by proxy, your proxy must carry written instructions to vote against every resolution you might later wish to contest, and the minutes must record your negative vote. A vague instruction to “protect my interests” will not make you an opposant; a recorded vote against will.
The severity of this standing rule is illustrated by a decision that reads like a warning addressed personally to non-French speakers. In a case decided on 4 June 2009 (appeal no. 08-10.493), a property company whose manager admitted he could not write French and had only a limited command of the language had voted in favour of a resolution authorising the managing agent to regularise a twelve-page settlement protocol drafted in dense legal language, which restricted the company’s commercial premises without any counterpart. The day after receiving the minutes, the manager wrote to protest that he had been misled and would never have voted yes had he understood the text. The Paris Court of Appeal accepted the annulment claim, reasoning that his blameless mistake was proven. The Cour de cassation quashed that ruling, censuring the appeal court in these terms: « Qu’en statuant ainsi, alors que le copropriétaire qui s’est prononcé en faveur d’une décision et ne démontre pas avoir été victime d’un dol, ne peut arguer de son erreur pour agir en annulation de cette décision, la cour d’appel a violé le texte susvisé ; » In English, a co-owner who voted for a decision and cannot show he was the victim of fraud cannot invoke his own mistake to have the decision annulled. Language difficulty, however genuine, is treated as a mistake, not as fraud.
The distinction between mistake and fraud comes straight from the Civil Code. Article 1132 of the Civil Code provides that a mistake of law or fact is a ground for nullity only in narrow conditions: « L’erreur de droit ou de fait, à moins qu’elle ne soit inexcusable, est une cause de nullité du contrat lorsqu’elle porte sur les qualités essentielles de la prestation due ou sur celles du cocontractant. » In English, a mistake counts only if it is excusable and bears on the essential qualities of what is owed. Article 1137 of the Civil Code defines fraud more demandingly and more usefully: « Le dol est le fait pour un contractant d’obtenir le consentement de l’autre par des manœuvres ou des mensonges. » Fraud means obtaining consent through scheming or lies, including the deliberate concealment of information known to be decisive. For the foreign owner who voted yes without understanding, the lesson of the 2009 ruling is therefore stark. Regretting your vote is not a case. Proving that the managing agent or another owner deliberately deceived you, with documents, can be one. If the meeting file contains a misleading presentation, a hidden annex or a false statement that pushed you to vote yes, preserve it immediately, because it is the only bridge back to standing.
Three further standing points complete the picture. First, the action is directed against the syndicat des copropriétaires represented by the managing agent, before the tribunal judiciaire (the ordinary civil court) of the place where the building stands, and representation by a lawyer is compulsory. Second, the claimant does not need to prove any personal loss: it is enough to show that the legal rules governing the meeting or the decision were breached. Third, the managing agent must notify the minutes within one month of the meeting, and if the minutes were never notified at all, the challenge period stretches to five years. That five-year safety net is the only generous deadline in the whole system, and it rewards owners who can prove they were kept in the dark.
B. The clock starts when the letter is presented, not when you read it
The April 2026 ruling settles the question every absent owner asks: from which day do the two months run? The facts were ordinary. A co-owner sought annulment of the resolutions of a general meeting held on 26 April 2022. The co-owners’ body objected that the action was out of time, and the Orléans Court of Appeal agreed, counting from the date the registered letter containing the minutes had first been presented at his home rather than the date he had actually collected it. The owner appealed to the Cour de cassation, arguing that the deadline should run from presentation only where the letter is never collected, and that applying the rule where the letter was eventually handed over breached his right of access to a court under Article 6, paragraph 1, of the European Convention on Human Rights.
The Court rejected both arguments categorically. On the starting point, it held that the statute draws no distinction according to whether the registered letter was collected: « La loi ne distinguant pas, selon que le pli recommandé est ou non retiré par son destinataire, pour fixer le point de départ du délai de deux mois pour agir en contestation des décisions d’une assemblée générale de copropriétaires, ce délai court, dans tous les cas, à compter du lendemain du jour de la première présentation de la lettre recommandée, de notification du procès-verbal de l’assemblée générale, au domicile du destinataire. » (appeal no. 24-18.842) In English, since the law makes no distinction based on collection, the two months run in every case from the day after the first presentation of the registered letter at the recipient’s home. Whether you were on holiday, whether the notice of attempted delivery sat in your mailbox, whether you collected the letter on the last day of the fifteen-day holding period at the post office: the counter started without you.
On the human-rights objection, the Court accepted that the rule restricts the time available to sue but found the restriction predictable and proportionate. The provisions are clear, their consequences foreseeable, and they do not destroy the substance of access to a court, because the owner has fifteen days to collect the letter and retains sufficient time to sue after collecting it: the judgment notes that the co-owner « dès lors que le copropriétaire, qui dispose d’un délai de quinze jours pour retirer la lettre recommandée, conserve un délai pour agir en justice suffisant, une fois le retrait de la lettre effectué. » (appeal no. 24-18.842) In English, the owner, who has fifteen days to collect the registered letter, keeps sufficient time to bring proceedings once collection has occurred. The rule pursues a legitimate aim, the legal certainty of collective building management and the enforcement of collective decisions, and a reasonable balance exists between the method and that aim. The European Convention argument therefore failed, and the owner was ordered to pay 3,000 euros under Article 700 of the Code of Civil Procedure.
The technical basis is worth stating precisely, because your lawyer will cite it. Article 18 of the Decree of 17 March 1967, in the wording given by the Decree of 2 July 2020, provides that the two-month period runs from notification of the minutes to each dissenting or absent co-owner. Article 64, first paragraph, of the same Decree, in the version applicable before the Decree of 22 December 2025, provided that notifications are validly made by registered letter with return receipt and that any resulting deadline starts the day after the first presentation of the letter at the recipient’s home. Since the Decree of 22 December 2025, managing agents may also notify minutes by electronic registered letter, and the same logic applies: the period runs from the moment the electronic notification notice reaches your inbox, which makes an unchecked spam folder as dangerous as an unvisited mailbox. Managing agents must keep the proof file for the electronic sending for at least five years. For a foreign owner, the defences are organisational, not legal. Give the managing agent a reliable postal address and an email address you actually monitor, authorise nobody to discard “French admin post” unread, calendar the meeting date plus six weeks as the latest arrival date for the minutes, and treat any delivery notice as a litigation deadline, because that is exactly what it is.
One final computation point matters. The action must be introduced, meaning the writ of summons (assignation, the bailiff’s writ that starts proceedings and summons the defendant) must be served, within the two months, not merely prepared or sent to your lawyer. A file handed to counsel in the eighth week with missing exhibits is a file at risk. Instruct early, because the forfeiture (déchéance, the automatic loss of the right to sue once the deadline expires) cannot be cured, suspended by negotiation or excused by good faith.
II. Winning on the merits and living with the result
Getting through the door in time is only half the battle. The court will annul a resolution only for defined legal defects, and the annulment, once granted, affects everyone in the building, including owners who never sued. Symmetrically, a resolution nobody challenged in time becomes final and enforceable even if it was irregular, and the co-owners’ body can then force compliance with it. Foreign owners need to understand both directions: how to build a winnable case, and why letting a deadline pass can later expose them to a court order to undo their own works.
A. The grounds that annul: procedure, majorities and abuse of majority
French courts annul meeting resolutions on a stable catalogue of grounds. Defects in the convening notice (late sending, missing documents, an incompetent sender), defects in the composition of the meeting (persons with no right to vote taking part, no chairman appointed), breach of the applicable majority rules, a vote on a question never placed on the agenda, and resolutions whose content violates the law or the building’s bylaws all qualify. The official service-public guidance confirms that any breach of the statutory rules on the organisation or functioning of the meeting, or on the decision itself, suffices. Two features favour claimants. No personal prejudice needs to be shown: an owner can have an irregular resolution annulled even where it cost him nothing. And the court examines each resolution separately, so one tainted vote does not necessarily sink the whole meeting, while one valid vote does not save a tainted neighbour.
Majority rules deserve special attention because they are the most frequent battleground and the most misunderstood by foreign owners. Ordinary management decisions are taken by a majority of the votes cast by owners present, represented or voting by post. More important decisions, such as most works affecting common areas, require heightened majorities, and the most sensitive measures require unanimity. In particular, the meeting cannot, by any majority, impose on an owner a change to the use of his private rooms or the terms of their enjoyment as set by the bylaws. A Paris appeal ruling of 11 March 2026 (Paris, Pole 4, Chamber 2, no. 22/17380) illustrates the analysis with surgical clarity. The meeting had resolved, by ordinary majority, to instruct the managing agent to have a notary draft a clause restricting the use of commercial premises. The dissenting owner cried foul, alleging breach of the voting rules and abus de majorité (abuse of majority, the misuse of majority voting power against the collective interest or to harm a minority owner). The court upheld the resolution: mandating a draft is an administrative step that an ordinary majority can order, and only the later adoption of the restrictive clause itself would require unanimity. The abuse-of-majority claim failed because the owner could not show that the resolution contradicted the collective interest or was designed to harm him. The lesson is general. Courts verify majorities resolution by resolution and stage by stage; a preparatory vote is judged as preparatory, and an abuse claim without proof of a purpose alien to the collective interest goes nowhere.
Abuse of majority remains, however, a genuine ground where the facts support it. A majority that votes works benefiting only its own members, that exempts itself from charges, or that blocks necessary maintenance to punish an unpopular owner misuses its power, and the resolution can be annulled with damages. Article 1240 of the Civil Code states the general liability principle: « Tout fait quelconque de l’homme, qui cause à autrui un dommage, oblige celui par la faute duquel il est arrivé à le réparer. » Any act that causes damage to another obliges the person at fault to repair it. In co-ownership litigation, that text supports the damages claim that usually accompanies the annulment claim where the abusive vote caused measurable loss, such as blocked sale, unusable premises or wasted costs. Two companion texts frame the reasoning courts apply. Article 1103 of the Civil Code recalls that lawfully formed contracts bind their makers: « Les contrats légalement formés tiennent lieu de loi à ceux qui les ont faits. » The co-ownership bylaws (règlement de copropriété, the binding document that allocates common and private areas and sets the rules of collective life) operate in the same spirit between co-owners, which is why a resolution contradicting the bylaws is vulnerable. And Article 544 of the Civil Code defines ownership as the right to enjoy and dispose of things in the most absolute manner compatible with the laws: « La propriété est le droit de jouir et disposer des choses de la manière la plus absolue, pourvu qu’on n’en fasse pas un usage prohibé par les lois ou par les règlements. » A resolution that strips an owner of the substance of that right, for instance by neutralising the commercial use guaranteed by the bylaws, attracts the strictest judicial scrutiny.
For the foreign owner preparing a case, the evidence list follows directly from these grounds. Keep the convening notice with its date stamp and annexes, the attendance sheet, the exact text of each resolution as put to the vote, the minutes showing how you voted, and every document presented at the meeting. Note who voted and with how many votes, since voting rights follow the ownership shares (tantièmes, the thousandths that measure each owner’s weight in the votes and charges). Photograph posted notices in the common areas. And where language is the issue, act before the meeting, not after: have the draft resolutions translated, send written questions to the managing agent in advance, and give your proxy holder explicit voting instructions in writing. Courts forgive an owner who organised his dissent; they do not forgive one who improvised it.
B. What annulment changes, and what silence costs
When the court annuls a resolution, the annulment is retroactive and collective. The resolution is deemed never to have existed, and the judgment binds all co-owners, including those who never went to court. Works carried out under an annulled resolution lose their legal basis, charges levied under it must be unwound, and the managing agent must draw the consequences in the accounts. Two statutory shock absorbers limit the blast. The annulment does not affect any owner’s duty to pay the ordinary collective charges, so a successful claimant cannot use the judgment as a pretext to stop paying. And acts concluded with bona fide third parties on the faith of the annulled appointment, for example contracts signed by a managing agent whose designation is later annulled, remain valid. The system undoes the internal irregularity without demolishing the building’s external dealings.
The mirror image is harsher, and a 2020 ruling gives it flesh. Co-owners had installed roof windows and replaced a gate and gateposts against the terms of two earlier meeting resolutions, one of 9 December 2006 standardising gate models and one of 23 June 2012 requiring a planned roof window to face outward so as not to create new views between houses. They had never challenged either resolution within the two-month period. When the co-owners’ body sued for removal and restoration, the owners argued that the body had no standing to enforce resolutions affecting private areas without showing harm to the collective. On 28 May 2020 (appeal no. 18-20.368), the Cour de cassation upheld the enforcement action, noting that its purpose was to apply decisions adopted in the collective interest and that the 2012 decision had never been challenged. In the Court’s words, the lower court had observed that the body’s action aimed at enforcing decisions adopted on behalf of the collective interest and that the resolution had not been contested. In English, an unchallenged resolution stands, and the co-owners’ body is entitled to have it obeyed. An irregular decision that nobody contests in time becomes definitive and binds everyone: that is the official guidance, and the 2020 ruling is its judicial twin.
For foreign owners, this finality cuts in two very practical directions. As a potential claimant, filing the minutes away and doing nothing for three months means the disputed works will proceed, the special assessment will be levied, and a later lawsuit will be thrown out on forfeiture before the merits are even examined. As the owner carrying out works to a Paris flat or a country house, it means checking the meeting resolutions that govern your project before instructing builders: gates, windows, air-conditioning units, terraces and external alterations are the classic subjects of standardising resolutions, and installing first while planning to argue later reverses the burden onto you. In both postures, the playbook is the same. Calendar every meeting and every delivery notice. Vote against in writing, through a proxy if absent, and verify that the minutes record your dissent resolution by resolution. On receiving the minutes, decide within days, not weeks, and instruct experienced real estate counsel in Paris early enough for the writ to be served inside the two months. Budget for the costs risk: the losing party bears the court costs and is routinely ordered to pay several thousand euros under Article 700, as the unsuccessful challenger discovered in the 2026 case. And keep every envelope, every return receipt and every email notification, because the whole dispute may turn on the date a letter was presented at a door you were not behind. Owners who treat the meeting minutes as the building’s most important legal document, which they are, will find French co-ownership law demanding but navigable; those who treat them as administrative noise will discover the forfeiture rule, as the case law shows, without mercy.

Conclusion
Challenging a French co-ownership meeting decision is a race run on three tracks at once. Only dissenting or absent owners may run, and a yes vote cast in a language you barely read closes the gate behind you unless deliberate deception can be proven. The clock starts the day after the registered letter is first presented, collected or not, and the highest court has now confirmed that this guillotine is compatible with the right of access to a judge. On the merits, courts annul for procedural defects, wrong majorities and abuse of majority, judging each resolution on its own stage, while an unchallenged resolution becomes final and enforceable even against owners who consider it unlawful. The foreign owner’s edge is therefore procedural discipline: monitored addresses, translated drafts, instructed proxies, recorded dissent, dated minutes and early instruction of counsel before the tribunal judiciaire. Master that discipline and the two-month window is wide enough; ignore it and no argument on the merits will ever be heard.
