Owning an apartment in a French building means you are part of a copropriété (co-ownership) governed by the Law of 10 July 1965. As a co-owner, you hold voting rights that shape the building’s budget, its maintenance schedule, and decisions that can reach directly into your private lot — from banning short-term rentals to authorising a rooftop extension. For a foreign owner who does not speak French, cannot attend meetings in person, or is simply unaware of the procedural safeguards, an assemblée générale (general meeting, or AG) can quickly become a source of legal exposure. The sums at stake are significant: a single vote on a façade renovation may commit you to several thousand euros in special levies, and a failure to challenge an irregular decision within the statutory deadline means paying regardless of whether you agreed or even knew about it. This article explains how French co-ownership meetings work, how to protect your vote and your financial interests, and what the most recent case law of the Cour de cassation (French Supreme Court, Third Civil Chamber) has clarified for all owners — domestic and foreign alike.

I. Understanding the French Copropriété General Meeting
A. What Is the Assemblée Générale and When Does It Convene?
The assemblée générale des copropriétaires is the sovereign decision-making body of the co-ownership. It is convened at least once a year by the syndic (property manager), who sets the agenda and sends the convocation (meeting notice) to every co-owner at least 21 days before the meeting, accompanied by supporting documents such as provisional accounts, draft contracts, and competitive quotes for proposed works. The meeting adopts resolutions on ordinary matters — approval of the annual accounts, election of the syndic, maintenance works — and on exceptional matters such as the sale of common areas or the modification of the co-ownership by-laws (règlement de copropriété).
A foreign owner who receives a thick envelope in French weeks before the meeting should not set it aside. The notice contains the agenda items on which a vote is requested. If you do not attend and do not grant a proxy, you will be counted as absent, and your silence will not block a decision that may later impose costs or restrictions on your lot. The law provides that the meeting is valid only if it is convened by someone who holds the proper authority to do so. The Cour de cassation has recently reinforced this requirement. In a ruling published in the Bulletin on 18 June 2026, the Third Civil Chamber held that a syndic whose appointment had been retroactively annulled was “dépourvu du pouvoir de convoquer l’assemblée générale” — “deprived of the power to convene the general meeting” — and that as a result, both the convocation and the entire meeting held pursuant to it were susceptible to annulment (Cass. 3e civ., 18 June 2026, no. 24-19.231, Publié au Bulletin). The court specified that a co-owner seeking nullity does not need to prove personal prejudice or fault by the manager: the procedural irregularity is sufficient on its own.
The meeting must also be properly constituted. A feuille de présence (attendance sheet) records the names, addresses, and voting strength of each co-owner present or represented. According to Cass. 3e civ., 13 June 2024, no. 22-17.764, “l’irrégularité affectant la composition d’une assemblée générale entraîne sa nullité sans qu’il soit nécessaire de justifier d’un grief” — an irregularity in the composition of a general meeting renders it void without the need to prove any specific harm. The Cour de cassation quashed an appeal court decision that had dismissed a nullity claim solely because the co-owner had not demonstrated personal prejudice, and remitted the case for reconsideration on the principle that the attendance sheet must accurately reflect who had voting authority. For a foreign owner who might not recognise the names listed or who suspects a person voting as proxy was not properly mandated, this case law provides a direct procedural weapon.
B. Who Decides What: Voting Thresholds and Decision-Making Rules
Not all resolutions are adopted by the same majority. The Law of 10 July 1965 establishes three tiers, and the distinction determines whether an owner who opposes a resolution can block it:
Article 24 — simple majority of all co-owners present or represented. This covers routine management: approval of accounts, budget votes, appointment or dismissal of the syndic, maintenance contracts, and most day-to-day decisions. A foreign owner who does not attend and does not give a proxy is not counted towards the quorum for this majority. The risk of absenteeism is therefore that the attending owners decide everything at this level without your voice.
Article 25 — absolute majority of all co-owners (present, represented, and absent). This applies to structural decisions: authorisation of works affecting common areas, appointment of a new syndic after a previous dismissal, modification of the use of common areas, and the decision to install collective equipment. If the required majority is not reached on first vote, a second vote may be held at a lower threshold (Article 25-1), but practical conditions apply.
Article 26 — double majority (majority of all co-owners representing at least two-thirds of the votes). Reserved for the most consequential decisions: sale of common areas, modification of the co-ownership by-laws, and the creation or suppression of specific services. Here, every vote counts and absenteeism can block the required thresholds altogether.
For a foreign owner, these tiered majorities have a practical consequence: a decision adopted at the Article 24 level that should properly have been passed under Article 25 or 26 is susceptible to annulment. If, for example, the syndic submits a major structural works resolution to a simple majority vote — and it passes — the owner who was absent or who voted against it can challenge the decision on the ground that the wrong majority threshold was applied. But the challenge must still be brought within two months of notification of the minutes. This interplay between substance and procedural deadlines is a recurring theme in French co-ownership litigation, and foreign owners should treat the notice period between receiving the convocation and the meeting date as a window for verifying that the proposed resolutions are allocated to the correct majority tier.
One recent decision illustrates illustrates what happens when an individual owner tries to bypass the collective decision-making framework. On 2 April 2026, the Cour de cassation ruled that “dans le silence du règlement de copropriété, le droit de surélever, pour créer de nouveaux locaux privatifs, un bâtiment qui comporte des parties communes, fussent-elles spéciales, appartient au syndicat des copropriétaires” — the right to raise a building to create new private units belongs to the co-ownership syndicate, not to the individual owner (Cass. 3e civ., 2 April 2026, no. 24-15.059, Publié au Bulletin). A property company (SCI) that owned the entirety of one building within a four-building complex had begun rooftop extension works without syndicate approval. The Cour de cassation confirmed the appeal court’s order to cease works and restore the roof to its prior state, under a daily penalty. The principle is clear: even if you own all the private lots in a building, if that building contains common areas — including special common areas — the syndicate alone may authorise or refuse elevated construction.
II. Protecting Your Rights as a Foreign Owner
A. Proxy Voting, Remote Participation, and Avoiding Nullity
Foreign owners who cannot travel to France for the annual meeting have two statutory options. The first is the pouvoir (proxy): any co-owner may delegate their vote to another person, whether or not that person is a co-owner. The mandate must be in writing and can be given to the syndic, the conseil syndical (co-ownership council), a neighbour, or a legal representative. A foreign owner should, however, be cautious about giving a blank proxy to the syndic — the property manager has a natural interest in certain resolutions (renewal of their own contract, approval of their management accounts) and may not vote in your best interest on those items.
The second option is voting by correspondence, now governed by the Ministerial Order of 2 July 2020 (Arrêté du 2 juillet 2020), which standardised the mail-in voting form. Co-owners must receive the form alongside the meeting notice and return it at least three days before the meeting. Several syndicates now offer secure electronic voting platforms, which are particularly useful for owners based in the United Kingdom, the United States, or Australia.
What should a foreign owner do upon receiving the convocation? First, verify the date and ensure at least 21 days’ notice has been given. Second, review the agenda and identify the proposed resolutions. If the notice is in French and you need a translation, many syndicates will provide a courtesy English summary upon request — but the French version remains the legally operative document. Third, determine whether any resolution could affect your lot directly: a vote on works in common areas, a change to the building’s use, or a special levy. If you oppose a resolution, you should record your opposition in writing or attend the meeting (or send a proxy) to vote against it; only an opposant (opposing voter) or a défaillant (absent co-owner) has standing to challenge the resolution later. A co-owner who voted in favour cannot later seek its annulment on the same grounds. Fourth, if you cannot attend, send a written proxy to a trusted person — a neighbour, a member of the conseil syndical, or your lawyer — with clear voting instructions for each resolution. A blanket proxy that says “vote as you see fit” is legally valid but practically hazardous, especially when the proxy holder is the syndic whose own fees and contract renewal are on the agenda.
Article 42 of the Law of 10 July 1965 also imposes a duty on the syndic: within one month of the meeting, the syndic must notify each co-owner of the meeting minutes. This notification triggers the two-month challenge window (see Part II.B below). If minutes are not notified within the statutory month, the two-month clock simply does not start running. A foreign owner who receives late or incomplete minutes should document the date of receipt, as this may preserve the right to challenge years later.
The Cour de cassation has also clarified the consequences of a co-owner’s apparent acquiescence to decisions. In Cass. 3e civ., 11 July 2024, no. 23-11.700, Publié au Bulletin, the court drew a sharp distinction between voluntary acquiescence — paying a judgment debt in execution of a court order — and a payment made by a notary under the statutory opposition mechanism in Article 20 of the 1965 Law. “Le paiement effectué par le notaire, en l’absence de contestation judiciaire formée par le copropriétaire vendeur, en conséquence de l’opposition faite par le syndicat des copropriétaires, ne peut caractériser un acquiescement” — payment by the notary, without judicial challenge by the seller co-owner, following opposition by the syndicate, does not constitute acquiescence. In plain terms: if the syndicate intercepts the sale proceeds of your lot by statutory opposition to recover alleged unpaid charges (as commonly happens when a foreign owner sells), and the notary releases the funds, that does not mean you have accepted the syndicate’s claim. You retain the right to challenge the underlying debt.
B. Challenging AG Decisions: The Two-Month Deadline and Recent Case Law
The most important rule for any co-owner, foreign or domestic, is compressed into Article 42, paragraph 2: “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, sans ses annexes.” In practice: once the syndic notifies you of the minutes, you have exactly two months to bring a legal challenge before the tribunal judiciaire. After that date, the decision becomes definitive. A foreign owner who leaves the notification envelope unopened for three months has lost the right to challenge — even if the decision was grossly prejudicial.
But the case law has progressively softened the edges of this apparently rigid deadline. The most useful development for a foreign owner comes from a published ruling of 4 July 2024: “une demande subsidiaire en annulation de diverses résolutions d’une assemblée générale tend aux mêmes fins que la demande en annulation de l’assemblée générale en son entier, de sorte que la demande subsidiaire étant virtuellement comprise dans la demande principale initiale, le délai de forclusion de l’action en nullité des décisions d’assemblée générale avait été interrompu par la délivrance de l’assignation en nullité de l’assemblée générale en son entier” (Cass. 3e civ., 4 July 2024, no. 22-24.060, Publié au Bulletin). In practical terms: if you file a lawsuit challenging the entire meeting within the two-month window, and later refine your claim to target only specific resolutions, the court will treat the initial challenge as sufficient to have interrupted the limitation period. The subsequent, more targeted claim is not time-barred.
This principle was reinforced — and refined — in a later ruling. On 16 October 2025, the Cour de cassation confirmed that a demand for annulment of several specific resolutions, though it “tend aux mêmes fins que la demande en annulation de l’assemblée générale en son ensemble,” must nevertheless comply with the procedural rules of appeal: the party must present the subsidiary claim in its first appellate submissions (Article 910-4 of the Code of Civil Procedure in its pre-2019 version) (Cass. 3e civ., 16 Oct. 2025, no. 24-10.606, Publié au Bulletin). A co-owner who, on appeal, abandons the initial blanket annulment request and newly seeks annulment of individual resolutions in second-instance submissions — rather than the first — will be declared inadmissible. The procedural discipline expected of litigants is strict, and foreign owners should assume that French courts will enforce it.
Two further procedural points deserve attention for the foreign owner. The first concerns the interaction between an administrator and a co-ownership syndicate in financial distress. In Cass. 3e civ., 9 July 2026, no. 24-21.794, the Cour de cassation held that an administrateur provisoire (court-appointed provisional administrator) of a dissolved secondary syndicate is not authorised to recover charges owed to the principal syndicate, because the administrator’s powers are confined to the statutory object of the secondary syndicate. For a foreign owner facing aggressive debt recovery by an interim administrator, this ruling provides a basis to verify the precise scope of the administrator’s judicial mandate.
The second concerns standing to seek annulment. The Cour de cassation has long held that a co-owner does not need to demonstrate personal harm in order to challenge a meeting. The 13 June 2024 ruling (cited in Part I.A above) is consistent with this line. A foreign owner who discovers, perhaps months after a meeting, that the syndic who convened it had an invalid or expired mandate — or that the attendance sheet listed phantom voters — should act promptly, but the case law does not require proof of financial loss as a precondition to standing.
Lastly, foreign owners should be aware that certain disputes between co-owners and the syndicate can fall under the general statute of limitations rather than the specific two-month challenge window. In a decision of 2 July 2026, the Cour de cassation applied Article 2224 of the Civil Code — the five-year limitation period — to a co-owner’s claim that an action against the syndicate did not qualify as a challenge to a specific AG resolution but rather constituted a personal action relating to the co-ownership (Cass. 3e civ., 9 July 2026, no. 24-21.794; see also Cass. 3e civ., 18 June 2026, no. 24-19.231). The characterisation of the action — is it a challenge to a resolution or an independent personal claim? — determines whether the two-month or the five-year clock applies. A foreign owner facing a complex dispute should seek legal advice to ensure the correct procedural path, since choosing the wrong one can be fatal.
Conclusion
A foreign owner cannot afford to treat the annual assemblée générale as a formality conducted in a language they do not understand. The decisions adopted in that meeting — approving a €30,000 roof repair, banning short-term rentals in the building, or authorising a rooftop extension that will block your apartment’s light — bind every co-owner, present or absent. The legal tools are precise: a written proxy given to a trusted mandatary who will vote according to your instructions, a mail-in ballot sent three days before the meeting, or electronic voting where the syndicate has implemented it. If a decision is adopted in violation of the rules, you have two months — not one day more — from notification of the minutes to issue a legal challenge. The case law of the Cour de cassation, particularly the 2024-2026 rulings reviewed above, has steadily reinforced the procedural rights of individual co-owners, including the right to challenge meetings convened by a manager whose mandate was retrospectively void, and the right to refine a blanket annulment claim into targeted challenges against specific resolutions without losing the benefit of the initial filing date. These are not abstract principles: they are levers available to an informed owner, and they are far less expensive to deploy early than to remedy late.
