You live in London, Singapore or New York. You own a two-bedroom flat near the Canal Saint-Martin that you let unfurnished to a tenant for 1,900 euros a month. Prices in the building have risen, you want to sell with vacant possession, or perhaps you plan to move back to Paris yourself next year. You email the tenant a polite three-month warning and expect the keys. Then a French friend tells you the truth: your lease renewed itself automatically, your email has no legal value, and if the notice you serve is defective by a single missing line, the tenant stays for another three years.<\/p>\n
Recovering a let flat in France is not a matter of ownership alone. It runs through one procedural door, the cong\u00e9 du bailleur<\/em> (landlord’s notice to vacate), governed by Article 15 of the Act of 6 July 1989, and that door only opens at the end of the lease, with six months’ warning, for one of three lawful reasons: selling, repossessing for yourself or a close relative, or a serious and legitimate ground. Foreign landlords lose cases on this terrain every month, not because their project was illegitimate, but because the notice omitted the price and conditions of the sale, named the wrong beneficiary, was served two weeks late, or targeted a protected elderly tenant without offering rehousing. This guide covers the full sequence as it stands on 7 October 2026 for unfurnished residential leases, the standard bail vide<\/em> (unfurnished lease): how to serve a notice that survives, how to choose and prove the motive, how tenants fight back and where their challenge fails, and how enforcement works in practice in Paris and the \u00cele-de-France for an owner who lives abroad.<\/p>\n The Cour de cassation repeats the architecture of Article 15, I in nearly every ruling on the subject: \u00ab lorsque le bailleur donne cong\u00e9 \u00e0 son locataire, ce cong\u00e9 doit \u00eatre justifi\u00e9 soit par sa d\u00e9cision de reprendre ou de vendre le logement, soit par un motif l\u00e9gitime et s\u00e9rieux, notamment l’inex\u00e9cution par le locataire de l’une des obligations lui incombant. \u00bb (Cass. 3rd civ., 12 October 2023, No. 22-18.580<\/a>). In plain English: when you give notice, it must be justified either by your decision to repossess or sell the dwelling, or by a serious and legitimate ground, such as the tenant’s breach of one of their obligations. Everything else in this field, deadlines, service methods, mandatory content, evidentiary battles, flows from that single sentence.<\/p>\n Start with the calendar, because most foreign owners discover it too late. For an unfurnished dwelling, the same ruling recalls that \u00ab Le d\u00e9lai de pr\u00e9avis applicable au cong\u00e9 est de six mois lorsqu’il \u00e9mane du bailleur. \u00bb (Cass. 3rd civ., 12 October 2023, No. 22-18.580<\/a>). In English: the notice period is six months when the notice comes from the landlord. The administration’s official guidance confirms the practical reading: the tenant must receive the notice letter at least six months before the end date of the lease, counting renewals (Service-public, notice given by the owner<\/a>). A notice served five months and three weeks before term, however genuine the project behind it, is void, and the lease rolls on for a full new period. Work backwards from the lease anniversary, then add a safety margin of several weeks: from abroad, post is slow, tenants travel, and a missed deadline costs three years, not three weeks.<\/p>\n Next, the method of service. The official guidance lists three valid channels: registered letter with acknowledgement of receipt, service by a commissaire de justice<\/em> (judicial officer, formerly the huissier<\/em> or bailiff), or electronic registered letter, but only if the individual tenant has previously accepted that method (Service-public, notice given by the owner<\/a>). For an owner living outside France, the hierarchy is clear. The judicial officer’s report is the gold standard: the notice period runs from the day the officer delivers or files the letter, and no tenant can later claim they never received it. A registered letter works, but the administration itself warns owners to post early precisely so that a judicial officer can still be instructed if the letter goes astray (Service-public, notice given by the owner<\/a>). Never serve notice by ordinary email, by a message through the rental platform, or by a phone call confirmed in writing. None of these is a valid channel, and a tenant who replies politely to your email has conceded nothing.<\/p>\n Then comes the content, where cases are truly won and lost. A landlord’s notice is void unless it states the ground relied upon and, for a repossession, the details of the beneficiary. The Cour de cassation states the rule in these terms: \u00ab A peine de nullit\u00e9, le cong\u00e9 donn\u00e9 par le bailleur doit indiquer le motif all\u00e9gu\u00e9 et, en cas de reprise, les nom et adresse du b\u00e9n\u00e9ficiaire de la reprise ainsi que la nature du lien existant entre le bailleur et le b\u00e9n\u00e9ficiaire de la reprise qui ne peut \u00eatre que le bailleur, son conjoint, le partenaire auquel il est li\u00e9 par un pacte civil de solidarit\u00e9 enregistr\u00e9 \u00e0 la date du cong\u00e9, son concubin notoire depuis au moins un an \u00e0 la date du cong\u00e9, ses ascendants, ses descendants ou ceux de son conjoint, de son partenaire ou de son concubin notoire. \u00bb (Cass. 3rd civ., 12 October 2023, No. 22-18.580<\/a>). In English: on pain of nullity, the notice must state the ground and, for a repossession, the name and address of the person for whom the flat is recovered plus their relationship to you, drawn from a closed list of yourself, spouse, civil-union partner, long-standing partner, parents and children, yours or your partner’s. A notice that says you are recovering the flat “for family reasons” without naming the beneficiary is void. A notice that names your nephew, your friend or your company is void, because none of them belongs to the statutory circle. For a sale, the notice must state the price and the conditions of the sale, again on pain of nullity, and it operates as an offer to the tenant, as explained below.<\/p>\n The sale route, the cong\u00e9 pour vendre<\/em> (notice to sell), is the foreign investor’s natural choice, and it carries a built-in buyer: the tenant. The notice must quote the price and conditions, and that quotation is a binding offer the tenant can accept within the statutory reflection period. If the tenant declines and leaves, the story does not end there. Where the owner later decides to sell on terms or at a price more favourable to the buyer, the notaire<\/em> (notary), or the landlord beforehand, must notify the former tenant of the new terms, on pain of nullity of the sale. The Cour de cassation recalls that \u00ab […] cette notification vaut offre de vente au profit du locataire. \u00bb (Cass. 3rd civ., 1 March 2023, No. 21-22.073<\/a>). In English: that notification counts as an offer of sale in favour of the tenant. This second-chance right, the droit de pr\u00e9emption subsidiaire<\/em> (subsidiary pre-emption right), produced a vivid illustration in the March 2023 ruling. Landlords had served notice to sell at 400,000 euros; the tenants left; seven months later the landlords signed a preliminary sale with new buyers at 380,000 euros including a 10,000-euro agency commission; the notary notified the former tenants, who exercised their pre-emption and bought, then refused to pay the agency commission. The appeal court sided with the agency, but the Cour de cassation quashed that decision entirely, holding that \u00ab En statuant ainsi, alors que le locataire qui exerce son droit de pr\u00e9emption subsidiaire en acceptant l’offre notifi\u00e9e par le notaire, qui n’avait pas \u00e0 \u00eatre pr\u00e9sent\u00e9e par l’agent immobilier mandat\u00e9 par le propri\u00e9taire pour rechercher un acqu\u00e9reur, ne peut se voir imposer le paiement d’une commission rench\u00e9rissant le prix du bien, la cour d’appel a viol\u00e9 les textes susvis\u00e9s. \u00bb (Cass. 3rd civ., 1 March 2023, No. 21-22.073<\/a>). In English: a tenant who exercises the subsidiary pre-emption right cannot be forced to pay a commission that inflates the price of the property, because the agent, who had been hired to find a buyer, played no part in bringing about that statutory sale. For the foreign seller, the operational lessons are threefold: never complete a sale at a lower price or on softer terms without the notary’s fresh notification to the departed tenant, on pain of nullity; budget for the possibility that the former tenant becomes your buyer; and do not promise your estate agent a commission on a pre-emption sale, because no court will make the tenant pay it.<\/p>\n The repossession route, the cong\u00e9 pour reprise<\/em> (notice to repossess), serves owners who want the flat back to live in, or to house a spouse, partner, parent or child. Its decisive feature is the standard of proof, and the October 2023 ruling is the reference every landlord’s file should be built around. First, the reassuring part: the requirement that you substantiate the genuine and serious character of your project is not a formal condition of validity. The court expressly approved the appeal judges for holding that the rule on justifying the real and serious nature of the decision, as a matter of form in the notice itself, is not prescribed on pain of nullity. In practice, your notice does not need to attach your life story; it needs the correct beneficiary details, and the proof comes later, before the judge. Second, the judge’s control is searching: \u00ab […] en cas de contestation, le juge peut, m\u00eame d’office, v\u00e9rifier la r\u00e9alit\u00e9 du motif du cong\u00e9 […] \u00bb (Cass. 3rd civ., 12 October 2023, No. 22-18.580<\/a>). In English: if the notice is challenged, the judge may verify of their own motion whether the ground is genuine. You cannot count on a passive tenant. Third, evidence that postdates the notice is admissible where it proves an intention that already existed when notice was served. In that case the landlord, a widower returning to his home region, proved his move with his registration on the electoral roll a year after the notice, invoices for major works carried out once the tenants had left, water, gas, electricity, internet and tele-assistance subscriptions taken out the following summer, and his change of address notified to the tax authorities. The court accepted all of it and validated the notice. Fourth, recovering the flat as your principal residence does not oblige you to give up a second home elsewhere; the landlord kept a residence in the south of France and still genuinely repossessed the flat as his main home. Build the file in that image from day one: a dated statement of your project, electoral registration or tax filings pointing to the flat, works invoices, utility subscriptions in your name. A repossession file is a paper house; judges move into it room by room.<\/p>\n The third route, the motif l\u00e9gitime et s\u00e9rieux<\/em> (legitimate and serious ground), is the flexible one, typically persistent arrears or breaches, and the administration is candid that the statute does not define it: the official guidance notes that the law has not precisely defined what counts as a legitimate and serious ground, so that if the tenant challenges the notice, the landlord must prove its validity before the judge (Service-public, notice given by the owner<\/a>). Use it only with documents that speak for themselves, a ledger of unpaid rent, unanswered formal demands, bailiff reports of misuse, because here, unlike a sale or a family repossession, there is no objective event for the judge to verify, only your account of the tenant’s behaviour. Note that in the October 2024 ruling discussed below, the landlord, a property company, had served notice on serious and legitimate grounds, and still lost, not on the ground itself but on the tenant’s protected status, which no ground can override without a rehousing offer (Cass. 3rd civ., 24 October 2024, No. 23-18.067<\/a>).<\/p>\n A valid notice on paper is only half the matter. Tenants challenge notices, protected tenants cannot be removed without rehousing, and a tenant who simply stays put must be removed by a court, not by a change of locks. This second half follows the dispute as it actually unfolds.<\/p>\n The tenant’s first weapon is nullity for formal defects: late service, missing price and conditions in a sale notice, unnamed or ineligible beneficiary in a repossession notice. These challenges succeed often, which is why Part I insisted on formalities. The second weapon is the allegation of fraud, the cong\u00e9 frauduleux<\/em> (sham notice): the tenant claims the sale or the family move was a pretext to get rid of them, to re-let at a higher rent or to sell without honouring the pre-emption. Here the burden allocation matters enormously for the foreign owner. The official guidance is explicit: if the disagreement reaches the judge, the tenant must be able to prove that the notice is fraudulent (Service-public, notice given by the owner<\/a>). Suspicion is not proof, and a landmark 1998 ruling shows how high the bar sits. A landlady had recovered a flat for her daughter under a notice validated in 1992; the daughter never moved in; the flat was ultimately re-let to another tenant of the building under a 1994 settlement; the evicted tenants sued for fraud and fault. The Cour de cassation upheld the appeal court’s finding that no fraud or fault on the owner’s part had been proved: the daughter’s failure to move in was explained by the building’s tangled reletting history and the owner’s overconfidence in everyone’s goodwill rather than by dishonesty (Cass. 3rd civ., 16 December 1998, No. 96-21.842<\/a>). But the ruling cuts both ways, and honest tenants should note the second half: the same appeal court had ordered the evicted tenants to pay damages for supposedly abusive proceedings, and the Cour de cassation quashed that order, holding that the appeal judges had punished the tenants for going to court without identifying any actual fault in how they exercised their right to sue (Cass. 3rd civ., 16 December 1998, No. 96-21.842<\/a>), in breach of the fault-based liability rule now codified at Article 1240 of the Civil Code, which provides that \u00ab Tout fait quelconque de l’homme, qui cause \u00e0 autrui un dommage, oblige celui par la faute duquel il est arriv\u00e9 \u00e0 le r\u00e9parer. \u00bb (Article 1240 of the Civil Code<\/a>). In English: any act that causes damage to another obliges the person through whose fault it occurred to repair it. The double lesson for the foreign landlord is practical: keep the paper trail that proves your project was genuine, because a documented move defeats a fraud claim, and do not assume that a tenant who challenges you in good faith will be punished for it, because courts protect the right to litigate. Note also, for owners who recycle arguments across successive disputes, that a decided validation binds only its own case: \u00ab L’autorit\u00e9 de la chose jug\u00e9e n’a lieu qu’\u00e0 l’\u00e9gard de ce qui a fait l’objet du jugement. \u00bb (Article 1355 of the Civil Code<\/a>). In English: a judgment’s binding force covers only what was actually decided.<\/p>\n The third weapon needs no proof at all, only arithmetic, and it is the trap that catches experienced investors: the protected elderly tenant. The October 2024 ruling states the shield in one sentence: \u00ab le bailleur ne peut s’opposer au renouvellement du contrat de location \u00e0 l’\u00e9gard de tout locataire \u00e2g\u00e9 de plus de soixante-cinq ans et dont les ressources annuelles sont inf\u00e9rieures au plafond de ressources en vigueur pour l’attribution des logements locatifs conventionn\u00e9s fix\u00e9 par arr\u00eat\u00e9 du ministre charg\u00e9 du logement, sans qu’un logement correspondant \u00e0 ses besoins et \u00e0 ses possibilit\u00e9s lui soit offert. \u00bb (Cass. 3rd civ., 24 October 2024, No. 23-18.067<\/a>). In English: you cannot refuse to renew the lease of a tenant over sixty-five whose annual income sits below the social-housing ceiling unless you offer them a replacement dwelling suited to their needs and means. Both conditions are assessed strictly. Age is measured at the end of the contract, and income is measured over the twelve months before the notice, assessed at the notification date: \u00ab […] les ressources \u00e0 prendre en compte […] sont celles per\u00e7ues par le locataire au titre des douze mois qui pr\u00e9c\u00e9dent la d\u00e9livrance du cong\u00e9. \u00bb (Cass. 3rd civ., 24 October 2024, No. 23-18.067<\/a>). In English: the income to count is what the tenant received over the twelve months preceding service of the notice. In that case a tenant whose declared income for December 2017 to November 2018 sat below the 2018 single-person ceiling kept his flat, and the property company’s notice was annulled for want of a compliant rehousing offer. Before serving any notice, ask your managing agent for the tenant’s age and, delicately but firmly, for evidence of income: a payslip, a tax notice, any recent file. If the tenant may be over sixty-five with modest means, price the cost of finding and funding a genuine replacement dwelling into your project, or reconsider the timing. No sale premium justifies a notice that the courts will annul as a matter of course.<\/p>\n Before the courtroom, the official path runs through conciliation. The tenant, and symmetrically the landlord seeking to defuse a dispute, can first write, then turn to the departmental conciliation commission or a justice conciliator, with the official guidance flagging that this step can be a mandatory gateway before the judge depending on the amount at stake (Service-public, notice given by the owner<\/a>). If disagreement persists, the competent court is the protection litigation judge, the juge des contentieux de la protection<\/em>, of the court where the dwelling is located, and representation by a lawyer is not compulsory there (Service-public, notice given by the owner<\/a>). Do not read that last point as an invitation to litigate alone from abroad: the procedure is oral, in French, and evidentially demanding, and everything about distance, language and proof argues for local representation.<\/p>\n In Paris and the inner suburbs, a valid notice rarely ends the story on the expiry date, and the foreign owner should plan the enforcement phase with the same rigour as the notice itself. If the tenant stays after a notice to sell or repossess, you must go to court to have the notice validated and the eviction ordered; self-help is prohibited. Never change the locks, cut off utilities, remove the front door, or move the tenant’s belongings to the pavement. Each of those acts exposes you to criminal liability and damages far exceeding a few months of lost rent, and it hands the tenant the moral and procedural high ground in the very proceedings you need to win. The competent judge is the protection litigation judge of the court where the dwelling sits, so for a Paris flat that means the Paris judicial court, and the case is conducted in French under an oral procedure where documentary proof carries the day (Service-public, notice given by the owner<\/a>). Owners based in Paris for the hearings hold no real advantage over owners abroad provided the file is complete, because judges decide on documents, not on attendance: the bailiff’s service report, the lease and its renewals, the rent ledger, the beneficiary’s identity documents and proof of relationship for a repossession, the price evidence and the notary’s notifications for a sale, and the age and income checks for the protected-tenant screen.<\/p>\n Timing is the second Paris reality. Even with a validated notice, no tenant may be physically removed during the winter truce, which runs from 1 November to 31 March inclusive each year, with only a rehousing solution suited to the tenant’s needs lifting the suspension (Service-public, when does the winter truce apply<\/a>). A notice expiring on 31 December therefore means effective recovery in April at the earliest, and Paris enforcement dockets add their own months. Price that delay into every decision: a sale with vacant possession scheduled for January should rest on a notice expiring no later than the previous spring, and a personal move planned for September should be backed by a notice served a full year ahead. The truce suspends removal, not the debt: rent and occupation indemnities keep running, and they are recovered through the same judgment.<\/p>\nI.
