Most foreign buyers negotiating a Paris flat obsess over the price per square metre and forget the building behind the front door. In French co-ownership, the expensive surprises rarely sit inside the apartment: they sit in the unpaid charges of the seller, the major works voted two years ago and payable in calls over the next three, and the syndic<\/em> (managing agent) who can freeze part of the purchase price to get paid. French law answers this risk with three paper checks produced at three different moments: the pr\u00e9-\u00e9tat dat\u00e9<\/em> (preliminary co-ownership disclosure pack) before you sign, the technical diagnostics file with the ten-day withdrawal right, and the \u00e9tat dat\u00e9<\/em> (dated statement) with its fifteen-day opposition window before the final deed. This guide explains what each document must contain, which deadlines truly block a sale, and how a buyer living abroad verifies charges, works funds and arrears before the notaire<\/em> (public conveyancing officer) releases a single euro.<\/p>\n

I. What the seller must put on the table before you sign anything<\/h2>\n

A. The preliminary disclosure pack: organisation, money, arrears and the works fund<\/h3>\n

Before the final deed, and in practice before the preliminary agreement, the seller must give you a standardised pack describing the co-ownership. Article L. 721-2 of the Construction and Housing Code<\/a> provides that “En cas de promesse de vente, sont remis \u00e0 l’acqu\u00e9reur, au plus tard \u00e0 la date de signature de la promesse, les documents et informations suivants :”, which means that where there is a preliminary promise of sale, the listed documents and information must be handed to the buyer no later than the date the promise is signed. If you sign a compromis de vente<\/em> (preliminary sale agreement) without this pack, you are flying blind on the one subject that generates most post-completion disputes between foreign buyers and syndics: money owed to and by the building.<\/p>\n

The pack has two halves. The first describes the organisation of the building: the summary sheet of the co-ownership, the r\u00e8glement de copropri\u00e9t\u00e9<\/em> (co-ownership bylaws) with the statement of division and any published amendments, and the minutes of the last three years of general meetings, unless the selling co-owner was unable to obtain them from the syndic. Read the bylaws for the allocation of charges between lots, the rules on works, pets, short-term letting and use of common areas, because anything written there binds you from the day you become owner. Read the three years of minutes next, and read them as a financial detective: look for votes on major works, for disputes with the builder, the syndic or neighbours, for decisions to sue, for exceptional calls, and for any mention of unpaid charges or of owners in difficulty. A quiet building with no works voted in three years and a tense building about to vote a full facade restoration look identical on a property portal; the minutes tell them apart. Where the seller says the minutes were unobtainable, treat that statement itself as a warning signal and ask the notaire to request them directly from the syndic before you commit.<\/p>\n

The second half of the pack is financial, and it is the half foreign buyers under-read. You must receive the amount of the current-budget charges and the off-budget charges paid by the selling owner for the two accounting years before the sale, the sums the buyer may owe to the syndicat, the overall statement of charge arrears within the syndicate and of the debt owed to suppliers, and, where the syndicate holds a works fund, the amount of the share of that fund attached to the flat being sold plus the last fund contribution paid by the seller for the lot. These figures must be current as of the annual meeting that approved the accounts preceding the signature of the promise. Concretely, three numbers deserve your full attention. First, the overall arrears of the building: a high arrears ratio means the syndic will chase paying owners harder, vote recovery proceedings, and possibly call exceptional advances that you will share. Second, the debt to suppliers: a building that owes its lift contractor or its insurer is a building where service interruptions and litigation are around the corner. Third, the works fund attached to the lot: that share stays with the flat and passes to you with it, so verify its amount rather than accepting a verbal assurance that the building is healthy.<\/p>\n

The works fund point traps many cross-border buyers twice. Because the share shown in the pack is attached to the lot, it travels with the flat to the buyer; do not let the price negotiation silently add a second payment reimbursing the seller for a fund you already receive with the property. Conversely, verify that the stated share actually exists: ask the notaire to reconcile the preliminary pack figure with the dated statement issued at completion stage, described in Part II below. If the two figures differ, ask why before signing the final deed, not after. The same reconciliation applies to the arrears statement: a building-level arrears figure that jumps between the promise and the completion usually means fresh defaults, fresh litigation, or both, and each of those changes the value of what you are buying even though the walls of your flat have not moved.<\/p>\n

One more check belongs to this stage even though the statute does not list it in the pack: the allocation key of your lot. The bylaws and the statement of division show the thousandths attached to your flat, and those thousandths decide both your votes and your share of every future call. Foreign buyers sometimes discover after completion that the charming top-floor flat carries a heavy share of lift or roof charges, or that the parking space they barely use carries its own allocation. There is nothing unlawful about either outcome, but both should be priced into your offer while you can still walk away, which is exactly what the ten-day withdrawal period discussed below is for.<\/p>\n

B. The technical diagnostics file and the ten days that let you walk away<\/h3>\n

Alongside the co-ownership pack, the seller must supply a technical diagnostics file. Article L. 271-4 of the Construction and Housing Code<\/a> provides that “En cas de vente de tout ou partie d’un immeuble b\u00e2ti, un dossier de diagnostic technique, fourni par le vendeur, est annex\u00e9 \u00e0 la promesse de vente ou, \u00e0 d\u00e9faut de promesse, \u00e0 l’acte authentique de vente.”, which means that on the sale of all or part of a constructed building, a technical diagnostics file supplied by the seller is attached to the promise of sale or, where there is no promise, to the final notarised deed. For a Paris apartment, expect the lead report, the asbestos survey, the termite statement, the gas installation report, the natural and technological risk statement, the energy performance report with any required energy audit, the electricity installation report, and the sanitation compliance document. Each of these follows its own validity rules, so check the dates: an expired diagnosis at signing can force a fresh survey, delay completion, or restart arguments about who pays for it.<\/p>\n

Diagnostics inform, but they do not replace the hidden-defects warranty, and foreign buyers should understand the boundary. Article 1641 of the Civil Code<\/a> provides that “Le vendeur est tenu de la garantie \u00e0 raison des d\u00e9fauts cach\u00e9s de la chose vendue qui la rendent impropre \u00e0 l’usage auquel on la destine, ou qui diminuent tellement cet usage que l’acheteur ne l’aurait pas acquise, ou n’en aurait donn\u00e9 qu’un moindre prix, s’il les avait connus.”, which means that the seller warrants hidden defects that make the property unfit for its intended use or diminish that use so much that the buyer would not have bought, or would have paid less, had he known. A diagnostic that correctly flags a defect generally moves that defect out of the hidden category; a missing, expired or plainly wrong diagnostic keeps the door open. And the clock is short: Article 1648 of the Civil Code<\/a> provides that “L’action r\u00e9sultant des vices r\u00e9dhibitoires doit \u00eatre intent\u00e9e par l’acqu\u00e9reur dans un d\u00e9lai de deux ans \u00e0 compter de la d\u00e9couverte du vice.”, which means that the buyer must bring the hidden-defects action within two years of discovering the defect. Keep every diagnostic, every invoice for surveys, and a dated record of when each problem first appeared; discovery date evidence decides these cases as often as technical evidence does.<\/p>\n

The preliminary agreement itself is already binding in substance, which surprises buyers from systems where only the final deed counts. Article 1583 of the Civil Code<\/a> states that “Elle est parfaite entre les parties, et la propri\u00e9t\u00e9 est acquise de droit \u00e0 l’acheteur \u00e0 l’\u00e9gard du vendeur, d\u00e8s qu’on est convenu de la chose et du prix, quoique la chose n’ait pas encore \u00e9t\u00e9 livr\u00e9e ni le prix pay\u00e9.”, which means that the sale is complete between the parties, and ownership passes to the buyer against the seller, as soon as thing and price are agreed, even before delivery or payment. The conditions precedent in the compromis then decide whether and how you can still exit, and the statute adds one unconditional exit for residential buyers: Article L. 271-1 of the Construction and Housing Code<\/a> provides that “l’acqu\u00e9reur non professionnel peut se r\u00e9tracter dans un d\u00e9lai de dix jours \u00e0 compter du lendemain de la premi\u00e8re pr\u00e9sentation de la lettre lui notifiant l’acte”, which means that a non-professional buyer may withdraw within ten days from the day after the first presentation of the letter notifying him of the agreement. Use those ten days actively from abroad: commission an independent review of the disclosure pack, have the minutes and the bylaws translated, and instruct the notaire in writing on the points to verify before completion. Withdrawal needs no reason, but it needs form and timing, so calendar the deadline on receipt and send the notice by a provable route.<\/p>\n

II. What the notaire verifies before completion: dated statement, opposition and the seller’s debts<\/h2>\n

A. The fifteen-day opposition window that protects the building, and indirectly the buyer<\/h3>\n

Between the preliminary agreement and the final deed, the notaire runs the co-ownership checks that decide whether the price flows normally or gets partially frozen. The centrepiece is the transfer notice and the opposition procedure. Article 20-I of the Law of 10 July 1965 on co-ownership<\/a> provides that “Avant l’expiration d’un d\u00e9lai de quinze jours \u00e0 compter de la r\u00e9ception de cet avis, le syndic peut former au domicile \u00e9lu, par acte extrajudiciaire, opposition au versement des fonds dans la limite ci-apr\u00e8s pour obtenir le paiement des sommes restant dues par l’ancien propri\u00e9taire.”, which means that for fifteen days after receiving the transfer notice, the syndic may file an out-of-court opposition to the payment of the funds, up to the statutory limit, to obtain the sums still owed by the former owner. In sequence: the notaire notifies the syndic of the transfer by registered letter within fifteen days of the ownership passing, unless the seller has produced a syndic certificate less than a month old confirming he owes the syndicate nothing; the syndic then has fifteen days from receipt to oppose payment of the price for the arrears of the former owner. Where seller and syndic agree on the sums due, the notaire releases the funds; where they disagree, the retained sums go to the syndicate within three months of a valid opposition unless a party challenges the opposition in court.<\/p>\n

Buyers sometimes read this as someone else’s problem, since the opposition targets the seller’s money. That reading misses the practical effects. First, an opposition delays and complicates completion: funds are retained, agreements must be negotiated, and court challenges suspend the flow. Second, the opposition reveals information you need: its existence proves the seller was in arrears, and its amount tells you how deep the problem ran. Third, payments made in breach of a valid opposition are unenforceable against the syndic, so a buyer who pressures the notaire to release everything quickly gains nothing and risks paying for the same debt twice through later calls. Ask the notaire, in writing and well before completion, whether any opposition has been filed, for what amount and on what grounds, and make the answer a condition of your completion checklist rather than a curiosity you discover at the signing table.<\/p>\n

The courts police this procedure strictly, and two rulings show what buyers should demand to see. In a 2011 ruling on two auction sales of lots belonging to the same owner, the Third Civil Chamber approved a court of appeal that had thrown out oppositions stated in identical figures for different groups of lots: Cass. 3rd civ., 3 November 2011, No. 10-20.182<\/a>, “l’opposition devait comporter, non seulement la r\u00e9partition des charges et des travaux selon le privil\u00e8ge ou le ” super privil\u00e8ge ” que le syndicat invoquait mais aussi le d\u00e9tail des sommes r\u00e9clam\u00e9es selon leur nature, et le lot auquel elles \u00e9taient aff\u00e9rentes”, which means that a valid opposition must break the claim down not only by the rank of privilege invoked but also in detail by nature of each sum and by the lot to which it relates. For a buyer, the lesson is concrete: where an opposition affects your purchase, demand the detailed breakdown by nature and by lot, and treat copy-pasted totals as vulnerable. In a 2001 ruling on a sale by forced auction initiated by the syndicate itself, the Court confirmed that the transfer notice is required even there: Cass. 3rd civ., 18 July 2001, No. 00-13.404<\/a>, “le d\u00e9lai pour former opposition et mettre en oeuvre le privil\u00e8ge des articles 2103 du Code civil et 19-1 de la loi pr\u00e9cit\u00e9e ne pouvait courir”, which means that without a properly sent transfer notice, the time limit for filing opposition and enforcing the special privilege could not even start to run. No notice, no foreclosure clock: check that the notice was sent and received, because every downstream deadline hangs from it.<\/p>\n

Behind the opposition stands a security that explains why syndics pursue sellers so aggressively: the legal mortgage over each lot. Article 19 of the Law of 10 July 1965<\/a> provides that “Les cr\u00e9ances de toute nature du syndicat \u00e0 l’encontre de chaque copropri\u00e9taire sont, qu’il s’agisse de provision ou de paiement d\u00e9finitif, garanties par une hypoth\u00e8que l\u00e9gale sur son lot.”, which means that all claims of the syndicate against each co-owner, whether provisions on account or final payments, are secured by a legal mortgage over his lot. Article 19-1 of the same Law<\/a> adds that “Toutes les cr\u00e9ances mentionn\u00e9es au premier alin\u00e9a de l’article 19 sont garanties par l’hypoth\u00e8que l\u00e9gale pr\u00e9vue \u00e0 l’article 2402 du code civil.”, which means that those claims carry the legal mortgage provided for by the Civil Code. And a valid opposition automatically triggers that security, since the statute states that a regular opposition counts as enforcement of the legal mortgage. For the buyer, the chain matters at completion: arrears secured by mortgage and enforced by opposition are the seller’s debts to clear from the price, not yours to inherit, provided the notaire’s apportionment separates them correctly.<\/p>\n

A related trap concerns the allocation of charges between seller and buyer at completion. The rule of thumb applied in conveyancing is that calls follow ownership: the seller answers for sums that fell due while he owned the lot, and the buyer answers for calls issued after the transfer, with the notaire drawing a day-count apportionment for the current period. Verify that apportionment line by line: provisions already paid by the seller for the period after completion should be credited back to him, and calls issued just before completion but covering future periods should not silently land on you. Where the seller’s arrears exceed the retained price, understand that the syndicate keeps its remedies against the former owner and its mortgage routes, but your flat must arrive free of the seller’s personal debt as between you and the syndic. If the figures do not reconcile, postpone completion rather than signing with a side promise to fix the accounts later; side promises between individuals do not bind the syndicate.<\/p>\n

B. The bad-payer certificate, the works fund at completion, and reading the minutes like an owner<\/h3>\n

Since 2024, the notaire must also run a forward-looking check that can block the sale entirely where the buyer already owns in the same building. Article 20-II of the Law of 10 July 1965 on co-ownership<\/a> requires the notaire, before drawing up the final deed and where applicable after the holder of the urban pre-emption right has waived it, to notify the syndic of the name of the prospective buyer, or of the managers and members of a purchasing property company with their spouses or civil partners. Within one month, the syndic issues a certificate less than a month old confirming either that these persons do not own in the building, or that those who do have not ignored a payment demand for more than forty-five days. The statute then states the sanction plainly: “Si le copropri\u00e9taire n’est pas \u00e0 jour de ses charges au sens du 2\u00b0 du pr\u00e9sent II, le notaire notifie aux parties l’impossibilit\u00e9 de conclure la vente.”, which means that where the co-owner is not current with his charges, the notaire notifies the parties that the sale cannot proceed. Where a preliminary agreement was already signed, the buyer-side persons notified have thirty days from the notification to pay what they owe the syndicate, failing which the preliminary agreement is deemed null and void through the buyer’s fault.<\/p>\n

Foreign investors expanding a Paris rental portfolio lot by lot are the first concerned: a dispute over charges on flat number one can freeze the purchase of flat number two in the same building, and the thirty-day cure period runs fast for someone managing paperwork from abroad. Keep every building current, answer payment demands within days rather than weeks, and before signing a new preliminary agreement in a building where you already own, ask the syndic for a written statement of your account. The forty-five-day threshold counts from an unsuccessful formal demand, so a demand letter sitting unopened in a Paris mailbox while you are abroad is the classic way to discover this rule at the worst moment. Practical organisation, a local address for service, and a property manager instructed to forward syndic mail the same day are not luxuries here; they are the difference between completing and watching a signed preliminary agreement collapse through your own fault.<\/p>\n

At completion, reconcile the works fund figure with the preliminary pack, as explained in Part I, and add one more document to the reconciliation: the dated statement itself, which itemises what the seller owes, what the buyer will owe, and what the building owes overall. Compare its arrears and supplier-debt figures with the pre-signing pack; any sharp movement needs an explanation in writing before funds move. Compare the list of voted but not yet called works with the minutes you read at the preliminary stage; works voted after the promise but before completion can add calls to your first year of ownership that no apportionment with the seller will cover unless your preliminary agreement says so. This is the moment to negotiate a price adjustment or a specific indemnity clause in the final deed, while the seller still needs your signature. After completion, the same works become your charges, voted by a meeting you did not attend, and the deploring letter to the syndic changes nothing.<\/p>\n

Finally, read the meeting minutes with an owner’s eyes on two limitation periods. Article 42 of the Law of 10 July 1965<\/a> provides that “Les actions en contestation des d\u00e9cisions des assembl\u00e9es g\u00e9n\u00e9rales doivent, \u00e0 peine de d\u00e9ch\u00e9ance, \u00eatre introduites par les copropri\u00e9taires opposants ou d\u00e9faillants dans un d\u00e9lai de deux mois \u00e0 compter de la notification du proc\u00e8s-verbal d’assembl\u00e9e, sans ses annexes.”, which means that challenges to meeting decisions must be brought by opposing or absent co-owners within two months of notification of the minutes, failing which the right is lost. When you review three years of minutes, note which controversial decisions were challenged and which became final: an unchallenged vote reallocating charges or approving expensive works is now part of the building’s settled law, and you buy into it. The same article extends the Civil Code five-year prescription to personal co-ownership actions between co-owners or between a co-owner and the syndicate, so recent payment claims in the dated statement usually sit well within time; do not count on limitation to erase the arrears figure you see. Buyers preparing a purchase in Paris often work through these papers with Paris real-estate counsel reviewing the co-ownership file before the final deed<\/a>, simply because the minutes, the statement and the opposition reply arrive in French, under deadlines counted in days, while the buyer sits in another time zone.<\/p>\n

Conclusion<\/h2>\n

Buying into a French co-ownership means buying two things at once: a flat and a share of a collective balance sheet. The preliminary disclosure pack tells you what the building is before you sign, the diagnostics file and the ten-day withdrawal right give you the information and the time to react, and the dated statement with the fifteen-day opposition window settles the seller’s debts from the price before they can become yours. Check the overall arrears and the supplier debt, reconcile the works fund between the promise and the completion, demand a detailed opposition breakdown by nature and by lot, verify that the transfer notice was sent, and keep your own account current where you already own in the building so the bad-payer certificate never blocks you. Run those checks in order, in writing, through the notaire, and the co-ownership mechanics become what they were designed to be: a filter that stops other people’s debts at the door of your new flat. For the building-specific questions that always remain, from reading three years of French minutes to negotiating the apportionment clauses of the final deed, the co-ownership conveyancing practice in Paris<\/a> handles exactly this file, in English, before completion rather than after the dispute.<\/p>\n","protected":false},"excerpt":{"rendered":"
