You have held the same French house for twenty years, you fly in for Easter, summer and Christmas, and you have never needed a visa. Then one Friday evening at the Gare du Nord or at Nice airport, the border officer frowns at the screen, counts on fingers, and tells you that you have exhausted your 90 days. Or worse: months later a letter orders you to leave France within thirty days and warns of a multi-year ban from returning. Since Brexit, British citizens are third-country nationals in the Schengen area: every short stay in France, Spain, Italy or Greece draws from a single shared allowance of 90 days in any 180-day period, and overstaying can end in a refusal of entry (refus d’entrée), a stay in the border holding area (zone d’attente), or a formal order to leave French territory (obligation de quitter le territoire français, universally shortened to OQTF). This article explains, for a British reader, how the count works, what officers can do when it goes wrong, and how to challenge each decision within the short time limits the law sets. French terms are translated at first use.
Read this before your next trip, not after a refusal. The 90-day count is rolling and backward-looking: the officer counts your presence over the 180 days before each entry, including trips you have half forgotten. The British government’s own travel advice for France confirms the headline rule and warns that visits to other Schengen countries in the previous 180 days count toward the same 90 days, and that overstaying can bring a ban from Schengen countries of up to three years — see the official gov.uk France entry-requirements page. What follows is the French-law machinery behind that warning.
I. How the 90/180-day count traps British visitors — and what happens when the border says no
Two moments decide everything: the arithmetic of your past trips, and the few hours at the border desk when an officer disputes it. British second-home owners are the classic casualties, because four long visits a year easily breach the ceiling while each visit feels short on its own. If you own the house itself, our companion guide on French property tax for British second-home owners covers the tax side; this article covers the border side. The two halves of this section take the count first, then the refusal.
A. Counting your 90 days across the whole Schengen area
The rule is one shared pot, not 90 days per country. Days spent anywhere in the Schengen area — France plus, among your likely destinations, Spain, Portugal, Italy, Greece, the Netherlands and Germany — all draw from the same allowance of 90 days within any rolling 180-day window. Days in Ireland do not count, because Ireland is outside Schengen; days in Britain obviously do not count either. Both the day you arrive and the day you leave count as full days of presence. A typical trap looks like this: 21 days at Easter in the Dordogne, 45 days in summer split between France and Spain, 30 days across autumn half-term and Christmas — 96 days inside a 180-day window, six days over, and an overstay recorded against your name even though no single trip looked excessive.
Work one concrete example through to the end, because the border officer will. You spend 16 December to 6 January in the French house (22 days counting both end days), 6 to 27 April around Bergerac (22 days), 13 July to 10 August split between the house and a week in San Sebastián (29 days), and 19 to 31 October for half-term (13 days). Enter France again on 20 December and the officer looks back to late June: the April trip has only just dropped out, the summer and autumn trips are inside, and the Christmas trip itself keeps adding days as it runs. Totals in the high eighties leave no margin for a delayed Eurotunnel crossing or an extra weekend — and crossing into the nineties turns a routine arrival into a refusal file. Recalculate before every single trip, against the planned return date, and treat anything above 80 days as a red light.
Three counting subtleties catch Britons out. First, the window rolls: on any given entry date, the officer looks back 180 days, so a long-ago trip drops out of the count only once it is more than 180 days behind you. Second, entries through other Schengen states still count: flying London–Malaga, driving up through Spain into France, and flying home from Bergerac is one continuous Schengen stay, and French territory rules then apply to the whole of it. The statute says so directly for people arriving overland from inside Schengen: « L’étranger en provenance directe du territoire d’un des États parties à la convention signée à Schengen le 19 juin 1990 peut se voir appliquer les 1° et 2° de l’article L. 611-1 lorsqu’il ne peut justifier être entré ou s’être maintenu sur le territoire métropolitain en se conformant aux stipulations des paragraphes 1 et 2 de l’article 19, du paragraphe 1 de l’article 20 et des paragraphes 1 et 2 de l’article 21 de cette même convention. » (CESEDA, Article L. 611-2). In plain terms, slipping into France by road from Spain does not reset anything. Third, a foreign alert follows you: France can enforce another Schengen state’s removal decision against a person flagged for non-admission who is unlawfully on French soil, since « L’étranger a fait l’objet d’un signalement aux fins de non-admission en vertu d’une décision de refus d’entrée ou d’éloignement exécutoire prise par l’un des autres États parties à la convention signée à Schengen le 19 juin 1990 et se trouve irrégulièrement sur le territoire métropolitain » (CESEDA, Article L. 615-1). A Spanish refusal can therefore bite on your next arrival in France.
Practical discipline beats cleverness. Keep every boarding pass, Eurostar ticket, motorway toll receipt and hotel invoice: since systematic passport stamping is being replaced by electronic recording, your own paper trail is your evidence if the count is disputed. Count before each trip using the 180 days behind your planned return date, not your departure date, and leave a margin of several days. If your life genuinely requires more than 90 days — retirement in the French house, extended family care — do not gamble on the border officer’s arithmetic: apply from Britain for a French long-stay visa before travelling, as explained in our British newcomer’s guide to French visas and residence cards. A visa-holder is outside the 90-day pot entirely.
B. Refused entry: the written decision, your rights, and the holding area
When the officer says no, the refusal is not a shrug and a turned back: it is a formal administrative decision with mandatory contents and immediate rights. The statute authorises it bluntly: « L’étranger qui ne satisfait pas aux conditions d’admission prévues au titre I peut faire l’objet d’une décision de refus d’entrée, sans préjudice des dispositions particulières relatives au droit d’asile et à la protection internationale ou à la délivrance de visas de long séjour. » (CESEDA, Article L. 332-1). Exhausted 90-day allowance, missing proof of accommodation or means, or an alert in the shared systems are the standard grounds for a Briton — not criminality, just arithmetic and paperwork.
Insist on the paper and read it before signing anything. The law requires that « La décision de refus d’entrée, qui est écrite et motivée, est prise par un agent relevant d’une catégorie fixée par voie réglementaire. » (CESEDA, Article L. 332-2). The notification must tell you of your right to warn, or have warned, the person you were to visit, your consulate, or a lawyer of your choice — and it must tell you of a right many travellers never learn they have: « Elle mentionne le droit de l’étranger de refuser d’être rapatrié avant l’expiration du délai d’un jour franc dans les conditions prévues à l’article L. 333-2 . » (CESEDA, Article L. 332-2). That jour franc, one full clear day, is breathing space: you cannot be put on the next plane home the same evening if you invoke it, which gives your family time to send the missing booking confirmations or instruct a lawyer. The same article adds that « La décision et la notification des droits qui l’accompagne lui sont communiquées dans une langue qu’il comprend. » (CESEDA, Article L. 332-2). If you were handed a French-only form you could not read, that defect matters for everything that follows.
Use the clear day actively. Call your consulate and a lawyer immediately — the notification itself tells you that you may warn them — and get relatives to email the missing evidence straight to you: the return booking, the hotel confirmations for the nights in question, the travel insurance, the proof of funds. Ask for every further document in writing and in English, note the names and numbers of the officers, and never sign a statement you cannot read. If you are travelling with children, say so at once and keep the family together: the statute singles out vulnerable people, especially accompanied and unaccompanied minors, for particular attention, and separation in the holding area is challengeable on that ground alone.
If return cannot happen at once, you may be held in the border holding area, the zone d’attente: a closed transit facility at the airport, port or station, not a police cell and not French soil in legal fiction — you are deemed not yet to have entered France. The first 96 hours rest on the administration’s decision, but beyond that a judge must authorise continued holding: « Le maintien en zone d’attente au-delà de quatre-vingt-seize heures à compter de la décision de placement initiale peut être autorisé, par le magistrat du siège du tribunal judiciaire statuant sur l’exercice effectif des droits reconnus à l’étranger, pour une durée qui ne peut être supérieure à huit jours. » (CESEDA, Article L. 342-1). Note what the judge examines: the effective exercise of your rights — interpreter, lawyer, doctor, contact with family — not whether the refusal was well founded. Owning a house in France, holding a return ticket and having family waiting do not, by themselves, spring the lock: « L’existence de garanties de représentation de l’étranger n’est pas à elle seule susceptible de justifier le refus de prolongation de son maintien en zone d’attente. » (CESEDA, Article L. 342-10).
A very recent Paris ruling shows the machinery in motion. On 9 May 2026 the Paris Court of Appeal overturned a first judge who had refused to extend a traveller’s holding, precisely because the first judge had reviewed the merits of the refusal itself (Paris Court of Appeal, 9 May 2026, docket no. 26/02575). The court recalled that the challenge to a refusal belongs to a different judge entirely, since the refusal is an administrative act « dont le contentieux échappe au juge judiciaire pour relever de la seule compétence du juge administratif » (Paris Court of Appeal, 9 May 2026, docket no. 26/02575). Finding the procedure regular as to the effective exercise of rights, it concluded: « Il convient donc d’infirmer l’ordonnance du premier juge et d’ordonner, en l’absence d’autres moyens et au regard de la régularité de la procédure quant à l’exercice effectif des droits reconnus à l’étranger, la prolongation du maintien en zone d’attente. » (Paris Court of Appeal, 9 May 2026, docket no. 26/02575). The lesson for a Briton held at Roissy or Coquelles: argue rights and procedure before the judicial judge, and attack the refusal itself before the administrative court — and note that cassation review of the holding order remains open, since « Le délai de pourvoi en cassation est de deux mois à compter de la notification. » (Paris Court of Appeal, 9 May 2026, docket no. 26/02575).
II. Overstaying inside France: the removal order, the return ban, and how to fight them
Getting past the border does not end the risk: prefectures, police checks and even a routine traffic stop can surface an expired allowance months later. Inside the territory, the instrument is no longer refusal of entry but the OQTF, usually paired with a voluntary-departure period and potentially followed by a ban on returning (interdiction de retour sur le territoire français, shortened to IRTF). This section separates the order itself from the remedies, because the remedies die in days while the order lasts for years.
A. The removal order, the thirty-day clock, and the return ban
The OQTF is the standard tool against overstayers, and its legal definition names your situation almost word for word. The administration may order a foreigner to leave where « L’étranger, entré sur le territoire français sous couvert d’un visa désormais expiré ou, n’étant pas soumis à l’obligation du visa, entré en France plus de trois mois auparavant, s’est maintenu sur le territoire français sans être titulaire d’un titre de séjour ou, le cas échéant, sans demander le renouvellement du titre de séjour temporaire ou pluriannuel qui lui a été délivré » (CESEDA, Article L. 611-1). A visa-exempt Briton who entered more than three months ago and holds no residence permit fits the second branch exactly. The same article covers clandestine entry, refused or withdrawn permits, rejected asylum claims, threats to public order and unauthorised work — but ordinary British overstay lives in that second clause.
An OQTF normally comes with time to leave on your own: « L’étranger faisant l’objet d’une décision portant obligation de quitter le territoire français dispose d’un délai de départ volontaire de trente jours à compter de la notification de cette décision. » (CESEDA, Article L. 612-1). Thirty days from notification — use them to organise departure, not to hope the letter goes away, because ignoring the clock triggers the harshest consequence. If you are still in France after the voluntary period expires, the administration moves from invitation to prohibition: « Lorsque l’étranger s’est maintenu irrégulièrement sur le territoire au-delà du délai de départ volontaire, l’autorité administrative édicte une interdiction de retour. » (CESEDA, Article L. 612-7). Humanitarian circumstances can excuse the ban, but the default is automatic, and its reach is long: « Les effets de cette interdiction cessent à l’expiration d’une durée, fixée par l’autorité administrative, qui ne peut excéder cinq ans à compter de l’exécution de l’obligation de quitter le territoire français. » (CESEDA, Article L. 612-7). Up to five years barred from France — and, through the shared alert systems, effectively from the Schengen area — for the sake of a miscounted summer. Serve the thirty days, keep proof of departure, and the ban normally never arises.
Two common British situations deserve a special warning. First, the pending-application trap: filing a carte de séjour request after the allowance has already expired does not neutralise an OQTF already notified, and prefectures routinely refuse late applications and order departure in the same envelope. File renewals and first applications months before expiry, never after a control. Second, the departure trap: leaving France quietly without keeping proof — no boarding pass, no stamped exit record, no dated receipt — can leave the file showing you still inside, with the voluntary period expiring on paper while you are already home in Kent. Depart through a controlled point, keep everything, and have your lawyer confirm the file records your exit.
B. Challenging the order before the administrative court — in days, not months
Every element of the package can be challenged — the OQTF, the residence decision behind it, the voluntary-departure period, and any accompanying return ban — but the challenge goes to the administrative court (tribunal administratif), never to the criminal or civil courts, and the clock is brutally short. The statute opens the door in one sentence: « La décision portant obligation de quitter le territoire français ainsi que la décision relative au séjour, la décision relative au délai de départ volontaire et l’interdiction de retour sur le territoire français qui l’accompagnent, le cas échéant, peuvent être contestées devant le tribunal administratif selon la procédure prévue à l’article L. 911-1. » (CESEDA, Article L. 614-1). A later return ban imposed after expiry of the departure period has its own route: it « peut être contestée devant le tribunal administratif selon la procédure prévue à l’article L. 921-1 ou, lorsque l’étranger est placé en rétention administrative, selon la procédure prévue à l’article L. 921-2. » (CESEDA, Article L. 614-4).
Under the fast-track procedure, the numbers leave no room for delay: « Lorsqu’une disposition du présent code prévoit qu’une décision peut être contestée selon la procédure prévue au présent article, le tribunal administratif peut être saisi dans le délai de sept jours à compter de la notification de la décision. » (CESEDA, Article L. 921-1), and « Sous réserve de l’article L. 921-4, il statue dans un délai de quinze jours à compter de l’introduction du recours. » (CESEDA, Article L. 921-1). Seven days to file, fifteen for the court to rule. Money must not be the reason you miss those seven days: « L’étranger peut demander le bénéfice de l’aide juridictionnelle, au plus tard lors de l’introduction de son recours. » (CESEDA, Article L. 911-1), meaning state-funded legal aid can be requested when the appeal is lodged.
Prepare the legal-aid request at the same time as the appeal, not afterwards. Bring the OQTF and all its annexes, your passport, proof of the date you received the letter, and evidence of your means — or lack of them — to the first meeting with the lawyer, because aid must be requested no later than when the case is filed and a late request cannot be repaired. If removal is imminent, your lawyer can also ask the court for interim protection freezing enforcement until the judgment: these emergency requests live or die on proof of urgency and serious doubt, so the day-by-day trip reconstruction and the procedural defects are their fuel as well.
What wins these appeals in practice is arithmetic and paperwork, not indignation. Rebuild the 180-day window day by day with tickets and receipts; show the miscount, the stamped visa that restarted the position, or the pending long-stay application that should have suspended removal. Attack the form as well as the substance: an unmotivated decision, notification in a language you do not understand, or a file that never mentions your British spouse, your French property, or your children’s schooling are all reviewable faults. And if the prefecture never gave voluntary departure at all — immediate-enforcement OQTFs exist for public-order cases — the deadlines compress further still, which is why the letter must go to a lawyer the day it arrives, not the week after.
Conclusion
The border and the prefecture both count; you should count first. Track every Schengen day against the rolling 180-day window, keep the tickets that prove it, and convert long French stays into long-stay visas applied for from Britain before you travel. If you are stopped, demand the written reasoned decision, invoke the clear day, and split your defence correctly: rights and procedure before the judicial judge in the holding area, the refusal itself before the administrative court. If an OQTF arrives, treat the seven-day appeal window as the emergency it is, prove departure within the thirty days, and never let a missed deadline harden into a five-year return ban.
