You have found the apartment in Paris, the stone house in the Dordogne or the small vineyard with a cottage attached. The price is agreed, the compromis de vente (preliminary sale agreement) is about to be signed, and your financing is in place. Then your notaire tells you that somebody else may buy the property instead of you, at the same price, and that there is nothing unfair about it. That somebody is a pre-emptor: the city, a rural land agency, or the tenant who already lives in the property. French law gives each of them a statutory right to step into your shoes, and a purchase file that has not cleared these rights on time is a file that can collapse months after signing. This guide explains the three pre-emption rights a foreign buyer meets in practice, the exact deadlines that decide everything, and what the Cour de cassation said about them in nine rulings you can check yourself.

The first reflex is to understand that pre-emption is not an exotic accident. In cities, the droit de préemption urbain (urban pre-emption right) covers vast areas, including the whole of Paris. In the countryside, the SAFER (rural land development and settlement agency) watches every sale of farmland and of many country properties with attached land. And where a home is rented, the sitting tenant is offered the property before any outsider. Each mechanism has its own notification circuit, its own clock and its own remedy when something goes wrong. The good news is that each of them is also strictly framed: a pre-emptor who misses its deadline loses its right, and a sale concluded without the mandatory notifications can be annulled. Your protection as a foreign buyer is therefore procedural, and it starts with instructing the notaire to purge every applicable right before you become bound unconditionally.

I. The public pre-emption rights that can take your purchase away

A. The city and its two-month window: urban pre-emption

Before any sale can go through inside a pre-emption zone, the owner must file a déclaration d’intention d’aliéner (declaration of intent to sell) at the town hall, and the sale cannot proceed until the holder of the right has answered or its time has run out. Article L. 213-2 of the Planning Code makes the declaration compulsory on pain of nullity and requires it to state the price and the conditions of the planned sale. The practical consequence for a foreign buyer is immediate: the price written in the declaration is the price the city can take, so the declaration must mirror the deal exactly, including who pays the estate agent, as one costly dispute shows below. Once the declaration is received, the holder has two months to decide, and silence counts as a waiver: « Le silence du titulaire du droit de préemption pendant deux mois à compter de la réception de la déclaration mentionnée au premier alinéa vaut renonciation à l’exercice du droit de préemption » (the holder’s silence for two months from receipt of the declaration counts as a waiver of the pre-emption right). That two-month period is suspended while the holder asks for documents or visits the property, and if less than one month remains when the clock restarts, the holder gets a full extra month. So the oft-quoted two months can stretch, and your completion date should be drafted with that elasticity in mind rather than against a fixed calendar.

The decision, when it comes, is published and notified to the seller, to the notaire and to the intended buyer named in the declaration, and the notaire passes it on to holders of related rights and to any tenant mentioned in the file. If the city pre-empts at the declared price, the evicted buyer simply loses the property; the sale with the city goes ahead instead. If the city considers the price excessive, it does not negotiate privately: the price is fixed by the expropriation judge. Article L. 213-8 of the Planning Code then organises the aftermath. Where the holder waived its right before any judicial price-fixing, the owner may sell at the declared price, adjusted if necessary for construction-cost index movements, but must complete the authentic deed within three years of the waiver or file a fresh declaration. And where the price was fixed by a court and the holder then walked away, it cannot pre-empt from the same owner again for five years from the final court decision. For a foreign buyer this means two things: a waiver is not a permanent clean bill for every future resale, and a judicial price dispute adds many months to the file, during which exchange-rate movements and loan-offer expiry dates keep running against you.

The price in the declaration also decides who pays the estate agent, a point buyers discover too late. In a Toulouse case, sellers had mandated an agent at 51,000 euros commission on the buyer’s account, then signed a unilateral promise of sale at 425,000 euros plus that commission, and the commune pre-empted. The courts had to decide whether the city owed the commission. The Cour de cassation quashed the appeal ruling and held that the pre-empting authority, for whose benefit the sale was effectively concluded, must bear the intermediary’s fee owed by the intended buyer whom it replaces, whenever the amount of the commission and the party bearing it appear in the parties’ agreement and in the declaration of intent to sell (Civ. 3rd, 12 May 2021, No. 19-25.226). The legal basis is the binding force of agreements: « les conventions légalement formées tiennent lieu de loi à ceux qui les ont faites » (lawfully formed agreements stand as law between those who made them). The lesson for a foreign buyer is symmetrical and uncomfortable: if your offer puts the commission on your side and the city steps in, the city pays the agent, not you, and you still lose the property. Check the commission clause before signing the offer, because it also fixes what the declaration will say and therefore what the city can take.

What if the pre-emption itself was unlawful and an administrative court annuls it after the transfer? The evicted buyer is not automatically put back in the property. Article L. 213-11-1 of the Planning Code requires the authority first to offer the property back to the former owner, and only if the former owner declines, to the evicted buyer. The price aims to restore the conditions of the blocked transaction without unjust enrichment of either side, and the court fixes it absent agreement. Here the Cour de cassation has set a trap for the impatient: in a case where the evicted company had accepted the retrocession offer by signing a promise of sale with the commune, it then tried to have the earlier sale annulled anyway, and the Court ruled it inadmissible (Civ. 3rd, 7 September 2022, No. 21-12.114, published in the Bulletin): « celui-ci n’est plus recevable à demander l’annulation de la vente conclue avec l’ancien propriétaire à compter de la date de la conclusion de la promesse de vente » (the buyer is no longer admissible to seek annulment of the sale concluded with the former owner from the date the promise of sale is concluded). Accept the fallback deal and you lose the annulment action; keep the annulment action and you must refuse the fallback deal. An evicted foreign buyer must choose its remedy with full knowledge, not sign whatever the commune puts on the table first. Readers managing a Paris purchase can ask our Paris real-estate practice to map these options before any signature.

The ultimate sanction for skipping the declaration altogether is nullity, and it lasts. The sanction lasts: « L’action en nullité prévue au premier alinéa se prescrit par cinq ans à compter de la publication de l’acte portant transfert de propriété » (the nullity action prescribes in five years from publication of the transfer deed) (Article L. 213-2 of the Planning Code). Five years is a long shadow over a resale, a mortgage and an insurance file. Before buying, therefore, have the notaire confirm in writing that the declaration was filed, what it contained, when the two months expired and what the answer was. A file with a clean, dated purge is the only file a foreign buyer should allow to become unconditional.

B. Farmland, vineyards and country houses with land: the SAFER

Outside the cities, a different pre-emptor watches: the SAFER of each region, whose mission is to protect farmland, settle farmers and improve plot distribution. Article L. 143-1 of the Rural Code, in its current version, gives the SAFER a pre-emption right over sales for consideration of farm-use buildings and their attached movables, and of bare land with an agricultural vocation, a category that covers protected agricultural zones, designated perimeters and, absent any planning document, undeveloped sectors of the commune outside woods and forests. A foreign buyer dreaming of a farmhouse with a few hectares, a paddock or a small vineyard is therefore squarely inside SAFER territory, even when the purchase is purely residential in the buyer’s mind. The notaire must notify the SAFER at least two months before the planned deed, and the agency must exercise its right before two months run from receipt of that notification. Its reasoned decision identifies the plots cadastrally, states the acquisition price and explains which statutory objective the pre-emption serves, as Article R. 143-6 of the Rural Code requires, and it is notified to the notaire and to the evicted buyer. Build the same purge discipline as in the city: no unconditional commitment before the two months expire or a written waiver arrives.

Clever contractual engineering does not defeat the SAFER. Sellers once tried splitting the deal, selling the usufruit (lifetime interest) to one person and the nue-propriété (bare ownership) to another at the same time, hoping each half would slip under the radar. The Cour de cassation closed that door: the deed transferred both rights at once, hence full ownership in a single operation even though usufruct and bare ownership went to two distinct buyers, and « l’aliénation était soumise au droit de préemption de la SAFER et devait être annulée » (the sale was subject to the SAFER’s pre-emption right and had to be annulled) (Civ. 3rd, 31 May 2018, No. 16-25.829, published in the Bulletin). The same ruling adds a sharp procedural point: the appeal court had itself recorded that « le notaire avait envoyé une déclaration d’opération exemptée du droit de préemption et non pas une notification valant offre de vente » (the notaire had sent a notice of an operation exempt from pre-emption, not a notification counting as an offer of sale), so the sanction for selling behind the agency’s back was nullity of the sale, without the SAFER being substituted for the buyer. A fake exemption notice is therefore worse than useless; it produces an annullable sale and no clean buyer.

The SAFER does not always buy for itself; it often redirects land toward farmers, including through tenants. The Court has approved the mechanism by which a SAFER allots land it acquires to a person who undertakes to lease it to an approved tenant, holding that « Ce dernier texte est applicable lorsque les sociétés d’aménagement foncier et d’établissement rural attribuent les biens par substitution en application de l’article L. 141-1, II, 2°, du code rural et de la pêche maritime. » (that text applies where the agencies allot property by substitution under Article L. 141-1, II, 2°) (Civ. 3rd, 11 July 2024, No. 22-23.678, published in the Bulletin; Article L. 141-1, II, 2° of the Rural Code). For the foreign buyer of a country estate, the practical meaning is that the competing project is often a working farmer with an approved lease plan, a profile the SAFER is statutorily built to prefer over a holiday home. Price and speed rarely beat that policy preference; only a file with no agricultural stake does.

Timing games around the SAFER’s promises were settled very recently. In a November 2025 ruling, a seller had granted the SAFER a unilateral promise of sale with a substitution faculty, the agency lifted the option while naming its substituted buyer, and the disappointed rival candidate cried foul, arguing the agency had never lifted the option for itself and that the substitution came too late (Civ. 3rd, 6 November 2025, No. 24-14.152). The Court rejected the challenge, finding that « la SAFER avait levé l’option dans les délais, lui permettant de se substituer tout acquéreur » (the SAFER had lifted the option in time, allowing it to substitute any buyer). Lifting the option on time while maintaining the substitution wish is valid, and the substitute can then be designated within six months of the promise acquiring a certain date. Foreign buyers should draw the operational lesson: a SAFER promise in the chain of title is a live file for months, and only the notaire’s dated tracking of each step tells you whether the land is truly free.

II. The sitting tenant who buys before you do

A. The housing tenant and the congé pour vendre

When the property you want is a rented flat, the first pre-emptor is already inside it. For an unfurnished home, the landlord who wishes to sell at the end of the lease serves a congé pour vendre (notice to vacate for sale), and that notice itself counts as an offer of sale to the tenant, who then has priority over outside buyers to purchase the home (official service-public guidance on selling a rented home). The offer stands during the first two months of the six-month notice period. The tenant accepts by registered letter, stating whether a mortgage loan will be used, and then has two months to sign the deed, extended to four months with a loan, with the notice period extended accordingly. If the tenant refuses, stays silent or makes a counter-offer the owner rejects, the offer lapses and the tenant must leave by the last day of notice. Critically, if the tenant accepts in time, any promise of sale already signed with an outside buyer is cancelled. A foreign buyer who signs a promise on a tenanted flat without checking the notice calendar may therefore hold a contract that the tenant’s single letter can wipe out.

The notice itself must reproduce the tenant’s statutory protections, but the courts are pragmatic about form. The Cour de cassation has held that a notice is formally valid where « la lettre de congé adressée à la locataire comportait en annexe un document, expressément annoncé dans le corps du congé » (the notice letter contained as an annex a document expressly announced in its body), even though the six opening paragraphs of Article 15-II of the Act of 6 July 1989 appeared in that annex rather than in the notice itself (Civ. 3rd, 18 February 2009, No. 08-11.114, published in the Bulletin). Form is forgiving, but substance is not: where the notice itself is void, the tenant’s pre-emption right dies with it, because « la nullité du congé ne laisse pas subsister le droit de préemption du locataire » (nullity of the notice leaves no surviving tenant pre-emption right) (Civ. 3rd, 9 November 2011, No. 10-23.542). Buyers should therefore have counsel read the actual notice served, not just its date: an irregular notice means no tenant priority but also a lease that continues, while a valid one means a live two-month tenant option hanging over the file.

Two money rules protect the tenant and surprise foreign sellers and agents. First, the tenant who pre-empts pays no agency commission. Second, where the tenant lets the first offer pass and the owner later agrees a lower price with an outside buyer, the owner must come back: the notaire notifies the tenant of the new offer, and the tenant holds a subsidiary pre-emption right. In a 2023 ruling the Cour de cassation held that « le locataire qui exerce son droit de préemption subsidiaire en acceptant l’offre notifiée par le notaire, qui n’avait pas à être présentée par l’agent immobilier mandaté par le propriétaire pour rechercher un acquéreur, ne peut se voir imposer le paiement d’une commission renchérissant le prix du bien » (the tenant exercising the subsidiary pre-emption by accepting the notaire-notified offer, which the owner’s search agent had no business presenting, cannot be made to pay a commission inflating the price) (Civ. 3rd, 1 March 2023, No. 21-22.073). A sale at a reduced price concluded without that second offer exposes the transaction to a court challenge by the tenant, so the buyer’s file must show both rounds were purged. The relative exception is narrow and verified: no tenant priority applies when a close relative up to the third degree buys to live in the home as a main residence for at least two years after the notice ends. Everything else runs through the tenant first.

One last tenant trap concerns buyers of occupied flats mid-lease rather than at lease end. During the lease, the tenant of a single flat is generally not a priority buyer, but the purchaser steps into the lease and cannot serve notice freely: the new owner’s notice only takes effect at the end of a two-year period running from the authentic deed. Two years of forced landlording, with rent control, maintenance duties and a tenant who knows the flat better than you, is the real price of skipping the lease analysis. Ask for the lease, the rent receipts, the notice history and the building’s sale-or-division status before any offer, because the pre-emption question is only one half of the tenanted-property risk.

B. The farm tenant and its two-month offer

Rural leases have their own sitting pre-emptor: the preneur à bail rural (farm tenant), whose right sits alongside the SAFER’s and ranks ahead of any outsider. Article L. 412-8 of the Rural Code organises a notarial circuit: once informed of the owner’s intent to sell, the notaire notifies the tenant by registered letter or bailiff’s writ of the price, charges, conditions and terms of the planned sale, and « Cette communication vaut offre de vente aux prix et conditions qui y sont contenus » (this communication counts as an offer of sale at the stated price and conditions). The civil-law rule that a promise of sale counts as a sale once thing and price are agreed applies to that offer, which is why Article 1589, paragraph 1, of the Civil Code is expressly invoked: « La promesse de vente vaut vente, lorsqu’il y a consentement réciproque des deux parties sur la chose et sur le prix » (a promise of sale counts as a sale where both parties mutually agree on thing and price). The tenant then has two months from receipt to send acceptance or refusal in the same forms, and the reply must actually reach the landlord within that period. A late reply is a refusal, and the file moves on without the tenant.

Formal notices frame the endgame, and limitation law punishes sleepers. Where the owner or the evicted buyer formally requires the pre-emptor to complete the authentic deed, the clock for challenging the pre-emption declaration runs from the expiry of that required period: the Cour de cassation holds that the nullity action against the pre-emption declaration prescribes in five years counted from the expiry of the deadline given by formal notice to execute the deed (Civ. 3rd, 14 December 2023, No. 22-11.505, published in the Bulletin): it « se prescrit par cinq ans à compter de la date d’expiration du délai imparti au préempteur par la mise en demeure » (prescribes in five years from the expiry of the period given to the pre-emptor by formal notice). That five-year measure echoes the general rule that Article 2224 of the Civil Code sets for personal actions: « Les actions personnelles ou mobilières se prescrivent par cinq ans à compter du jour où le titulaire d’un droit a connu ou aurait dû connaître les faits lui permettant de l’exercer » (personal and movable actions prescribe in five years from the day the right-holder knew or should have known the facts allowing its exercise). For a foreign buyer this means the farm-tenant question never fully dies on informal reassurances; it dies on dated notifications, receipts and expiries kept in the notaire’s file. Where farmland is involved, buy the paper trail first and the landscape second.

Conclusion

Three different pre-emptors can lawfully take the French property you thought you had secured: the commune or public body inside an urban pre-emption zone, the SAFER over farmland and country land, and the sitting tenant, housed or farming, whom the notaire must serve before any outsider. Each right runs on notifications and short clocks, two months in every circuit described here, and each one punishes the party that treats paperwork as a formality: nullity within five years for a skipped urban declaration, nullity without substitution for a disguised rural sale, cancellation of your promise when a tenant accepts in time. The foreign buyer’s defence is the same in all three cases and it is entirely practical: make every offer conditional on written proof that each applicable right was purged, calendar the two-month windows from receipt rather than from sending, verify the price and commission lines that the pre-emptor can take over, and refuse to become unconditional on a verbal waiver. Done properly, pre-emption clearance is a routine administrative step; done loosely, it is the dispute that eats your deposit, your loan timetable and your moving date. If a notice, a declaration or a tenant’s letter has already landed on your file, bring the dated documents to our Paris real-estate team before answering, because the next deadline is always shorter than it looks.
