Your mother has lived in France for fifteen years. She owns a flat in Paris, banks with a French high-street bank, and signed an English lasting power of attorney — the English-law instrument appointing someone to manage her property or welfare if she loses mental capacity — well before the first signs of dementia. Now the bank has frozen online transfers, and the notaire (the French public officer who alone can complete a property sale) refuses to sell the Dordogne cottage on the strength of that English document. This article explains what an English lasting power of attorney, universally known as an LPA, is worth in France after Brexit, how to give it its best chance, and which French protection measure to open when the bank or the notaire says no. Every French term is explained the first time it appears.

The short answer is that an LPA works smoothly within England and Wales but arrives in France as a foreign paper which no statute obliges a French bank or notaire to honour automatically. Your strongest file therefore combines the registered LPA with an apostille (the standardised certificate authenticating a document for use abroad), a translation by a traducteur assermenté (a sworn translator registered with a French court of appeal), and proof the document was valid where signed. Where that file is still refused, French law offers three domestic routes: the mandat de protection future (the French future protection mandate, signed in advance for incapacity), the habilitation familiale (a family authorisation granted by the guardianship judge), and full judicial protection as tutelle (guardianship) or curatelle (a lighter supervision regime). The Court of Cassation (Cour de cassation, France’s highest civil court) has already drawn the boundaries of what an apostille proves and when a judge may replace a mandate with a court measure. This guide sets out each step, the papers to gather, Paris practice, and the remedies — the application to the juge des tutelles (the guardianship judge) and the appeal — that unblock a frozen file.

I. Will a French bank or notaire accept your English lasting power of attorney?

A. What an English LPA is and how France reads it: a foreign private mandate

Start with the English side, because everything you present in France must first be regular in England. The official guidance on making and registering a lasting power of attorney explains that the donor must be at least 18 and still have mental capacity — the ability to make their own decisions — when the LPA is made It adds a point that matters for Britons settled abroad: neither living in the United Kingdom nor holding British citizenship is required to make one An LPA therefore remains available to a British retiree already living in the Dordogne, provided she still had capacity when she signed. There are two kinds — property and financial affairs on the one hand, health and welfare on the other — and neither has any effect until a distinct second step is complete: registration with the Office of the Public Guardian, currently advertised at eight to ten weeks where the application contains no mistakes Registration is what turns a signed form into an operative instrument, and the published fee position is £92 per instrument applied for, subject to a reduction or exemption in some cases Keep the registration confirmation from the Office of the Public Guardian with the original document: it is the first paper a French bank will ask to see, because an unregistered LPA is, in English law itself, simply not yet usable.

Cross the Channel and the analysis changes completely. French law knows the mandat (the mandate, the contract by which one person gives another the power to act in their name), and Article 1984 of the Code civil (the French civil code) defines it word for word: “Le mandat ou procuration est un acte par lequel une personne donne à une autre le pouvoir de faire quelque chose pour le mandant et en son nom.” An English LPA looks, to French eyes, like a foreign mandat: a private writing, signed before English witnesses, often with no French notaire anywhere in the chain. That characterisation decides which probative rule applies. Article 47 of the civil code governs foreign civil-status instruments and provides, word for word: “Tout acte de l’état civil des Français et des étrangers fait en pays étranger et rédigé dans les formes usitées dans ce pays fait foi, sauf si d’autres actes ou pièces détenus, des données extérieures ou des éléments tirés de l’acte lui-même établissent, le cas échéant après toutes vérifications utiles, que cet acte est irrégulier, falsifié ou que les faits qui y sont déclarés ne correspondent pas à la réalité.” A regularly signed and registered LPA therefore starts with a presumption of regularity — fait foi, it is taken as proving what it states — but that presumption is rebuttable, and the bank or notaire is entitled to carry out toutes vérifications utiles (all useful checks) before releasing funds or authenticating a sale. Refusal is not, as such, unlawful: for a notaire, who engages personal liability on every acte authentique (the formal notarised deed that alone transfers French land), accepting a doubtful foreign power is a professional risk, and caution is built into the office.

Three practical objections recur, and you should test your file against each before presenting it. First, scope: a property-and-affairs LPA does not appoint you as owner, it authorises defined acts, and many LPAs contain restrictions — no gifts above a threshold, no sale of a specified property, joint appointment requiring two signatures — which the French reader will apply literally. Second, timing: an LPA signed after capacity was already lost is void in English law, and a French judge asked to enforce it will want evidence of capacity at signature, ideally a contemporaneous attendance note from the English solicitor. Third, form for land: selling French land requires an acte authentique received by a French notaire, and most notaires will only act on a foreign power that is apostilled, sworn-translated, and, for high-value sales, confirmed by a French legal opinion (consultation juridique, the written advice of a lawyer on the applicable law). None of this means the LPA is worthless — it means it is the opening of the file, not the whole file. Families who grasp this early avoid the classic trap: presenting a bare photocopy of the LPA at the bank counter, being refused, and concluding that nothing can be done, when the refusal letter simply lists the missing authentications.

B. How to give your LPA its best chance: apostille, sworn translation and proof pack

The single most useful authentication is the apostille issued under the Hague Convention of 5 October 1961 abolishing legalisation for foreign public documents. For an English LPA this means the Foreign, Commonwealth and Development Office apostille, applied to the registered instrument or to a certified copy, confirming the signature and seal of the certifying officer. What exactly that certificate proves was settled by the First Civil Chamber of the Court of Cassation on 13 May 2020 (appeal no. 19-11.374, reported in the Bulletin, Court of Cassation, First Civil Chamber, 13 May 2020, no. 19-11.374). The court recalled, word for word: “Aux termes de l’article 5, alinéa 2, de la Convention de La Haye du 5 octobre 1961 supprimant l’exigence de la légalisation des actes publics étrangers, l’apostille dûment remplie atteste la véracité de la signature, la qualité en laquelle le signataire de l’acte a agi et, le cas échéant, l’identité du sceau ou timbre dont cet acte est revêtu.” An apostille therefore proves the origin of the paper — whose signature, in what capacity, which seal — and nothing more. It does not certify that the donor had capacity, that the attorneys remain appointed, or that the LPA covers the act you propose. The same ruling adds the second half of the lesson, word for word: “Si l’article 7 de ce texte impose la tenue obligatoire d’un registre destiné à permettre un contrôle a posteriori des apostilles délivrées dans chaque Etat partie par l’autorité habilitée, la vérification qu’il autorise revêt un caractère facultatif et vise exclusivement à permettre à l’autorité de l’Etat destinataire de s’assurer, le cas échéant, de l’origine de l’apostille en prenant contact avec l’autorité de l’Etat qui est censée l’avoir émise.” The receiving authority may check the issuing register, but it does not have to, and a court that finds the apostille authenticates the wrong signature — in that case a third party’s rather than the registrar’s — is entitled to hold, without further enquiry, that the document cannot take effect in France. Draw the operational conclusion: apostille the right document, in the right chain — the registered LPA as issued or a copy certified by the proper officer — because an apostille on an odd copy invites the exact rejection the Court of Cassation approved.

Translation comes next, and here French practice is strict. Banks and notaires expect a full translation by a traducteur assermenté, attached to the apostilled original, with the translator’s stamp, signature and court-of-appeal registration number on every page. A home-made translation, or even an excellent translation by an unlisted professional, is routinely returned. Assemble what experienced files call the proof pack (dossier de preuve, the bundle of documents establishing your authority): the registered LPA with its Office of the Public Guardian validation page; the apostille; the sworn translation; photographic identification for donor and attorneys; recent proof of the donor’s address in France (utility bill, taxe foncière bill); the English solicitor’s file note on capacity at signature where one exists; and, where attorneys have changed or one has died or disclaimed, the supporting deeds. Present this pack in one indexed bundle, keep a copy, and ask the bank for a written decision: a refusal letter naming the missing item is the document on which everything else turns, because it tells you whether you face a curable authentication gap or a policy refusal that only a French court measure will cure. Where the bank invokes anti-fraud or anti-money-laundering checks, comply in writing, set a reasonable deadline, and keep every exchange: the paper trail later proves to the guardianship judge that the family route was tried first and that funds are genuinely blocked, which is precisely what makes an urgent application credible.

One related English instrument deserves a warning. The older enduring power of attorney (the EPA, the pre-October-2007 English form) and informal letters of authority carry far less weight: EPAs were never designed for registration in the modern sense, and French readers treat them with visible suspicion. Likewise, a health-and-welfare LPA has almost no direct purchase in France, where medical and personal decisions for an incapacitated adult follow French health and guardianship law rather than an English deed. Spend your authentication budget on the property-and-affairs LPA — apostille, sworn translation, proof of registration — and do not be surprised if the bank accepts that instrument for day-to-day management while the notaire still refuses it for a sale. That split outcome is normal: moving money within an account is reversible, transferring land by acte authentique is not, and the notaire‘s liability explains the higher bar. When the sale cannot wait, the answer is not to argue longer with the notaire but to open the French measure described in Part II, with the LPA annexed as evidence of the donor’s wishes — a use to which the guardianship judge is far more receptive than the conveyancing office.

II. If the LPA is refused: which French protection measure to open and how to challenge a refusal?

A. The three French routes: future protection mandate, family authorisation, guardianship

French law starts from a threshold question that many British families have never had to articulate: is the person medically unable to look after their own interests? Article 425 of the civil code answers it word for word: “Toute personne dans l’impossibilité de pourvoir seule à ses intérêts en raison d’une altération, médicalement constatée, soit de ses facultés mentales, soit de ses facultés corporelles de nature à empêcher l’expression de sa volonté peut bénéficier d’une mesure de protection juridique prévue au présent chapitre.” Note the two cumulative demands: an altération médicalement constatée (a medically certified impairment) of mind or body, and resulting inability to provide for one’s own interests. Old age alone, eccentricity, or a bad financial decision do not satisfy this test; a detailed medical certificate (certificat médical circonstancié, the reasoned certificate describing the impairment) does. Everything that follows — mandate, family authorisation, guardianship — hangs on that certificate, and files fail more often on weak medical evidence than on any point of law.

The first route is the one closest in spirit to the English LPA: the mandat de protection future, available to anyone who plans ahead. Article 477 of the civil code opens it word for word: “Toute personne majeure ou mineure émancipée ne faisant pas l’objet d’une mesure de tutelle ou d’une habilitation familiale peut charger une ou plusieurs personnes, par un même mandat, de la représenter pour le cas où, pour l’une des causes prévues à l’article 425 , elle ne pourrait plus pourvoir seule à ses intérêts.” The same article fixes the form, word for word: “Le mandat est conclu par acte notarié ou par acte sous seing privé.” The choice of form matters enormously. A mandate signed as an acte sous seing privé (a private deed, signed without a notaire) is valid for everyday management but cannot authorise disposals of property; only the acte notarié (the notarised form, received by a notaire) empowers the agent to sell land. The official English-language guidance on the future protection mandate confirms the divide: the private-signature mandate is written and signed between the parties without going before a notary, while the mandate drawn up by a notary is an authentic act carrying full powers. British readers should also note Article 478 of the civil code, word for word: “Le mandat de protection future est soumis aux dispositions des articles 1984 à 2010 qui ne sont pas incompatibles avec celles de la présente section.” The French mandate is therefore an ordinary mandate plus a protective shell — which is exactly why a French notaire understands it at once while an English LPA requires explanation. Where the donor’s wishes extend to the person as well as the property, Article 479 of the civil code channels them through French safeguards, word for word: “Lorsque le mandat s’étend à la protection de la personne, les droits et obligations du mandataire sont définis par les articles 457-1 à 459-2 .” Activation is administrative rather than judicial: Article 481 of the civil code provides, word for word: “Le mandat prend effet lorsqu’il est établi que le mandant ne peut plus pourvoir seul à ses intérêts.” The agent then files the mandate with the registry (greffe, the court office) of the tribunal judiciaire (the ordinary civil and criminal court) together with the listed doctor’s certificate — “A cette fin, le mandataire produit au greffe du tribunal judiciaire le mandat et un certificat médical émanant d’un médecin choisi sur la liste mentionnée à l’article 431 établissant que le mandant se trouve dans l’une des situations prévues à l’article 425 ” — and “Le greffier vise le mandat et date sa prise d’effet, puis le restitue au mandataire.” No hearing, no judge, a clerk’s endorsement: that speed is the great attraction of the French mandate for a British family that planned ahead, and the great reason to sign one now even where an English LPA already exists.

The second route, and often the best fit for a British family facing an immediate block, is the habilitation familiale: a close relative authorised by the judge to represent, assist, or conclude specified acts for the vulnerable person. Article 494-1 of the civil code frames it, word for word, for the case “Lorsqu’une personne est dans l’impossibilité de pourvoir seule à ses intérêts en raison d’une altération, médicalement constatée soit de ses facultés mentales, soit de ses facultés corporelles de nature à empêcher l’expression de sa volonté”, providing that “le juge des tutelles peut habiliter une ou plusieurs personnes choisies parmi ses ascendants ou descendants, frères et sœurs ou, à moins que la communauté de vie ait cessé entre eux, le conjoint, le partenaire auquel elle est liée par un pacte civil de solidarité ou le concubin à la représenter, à l’assister dans les conditions prévues à l’article 467 ou à passer un ou des actes en son nom”. A daughter from London, a brother from Manchester, a French-resident spouse: all sit inside the eligible circle, and the authorised person acts free of charge — “Elle exerce sa mission à titre gratuit.” Compared with full guardianship, family authorisation is lighter, faster, and usually requires no annual accounts where the order so provides; it can be general or limited to named acts such as selling the Dordogne cottage or operating specified accounts, which makes it the natural answer to a bank that demands “a French court paper” for one blocked transaction. Ask for general authorisation where the impairment is global, and for act-specific authorisation where one sale or one account is the entire problem: judges grant what the medical certificate supports, and a certificate describing total loss of financial understanding supports more than one complaining of occasional forgetfulness.

The third route is full judicial protection — sauvegarde de justice (a short-term court safeguard), curatelle, or tutelle — and it is governed by two principles of restraint that British applicants sometimes overlook. Article 428 of the civil code states the subsidiarity rule word for word: “La mesure de protection judiciaire ne peut être ordonnée par le juge qu’en cas de nécessité et lorsqu’il ne peut être suffisamment pourvu aux intérêts de la personne par la mise en œuvre du mandat de protection future conclu par l’intéressé, par l’application des règles du droit commun de la représentation, de celles relatives aux droits et devoirs respectifs des époux et des règles des régimes matrimoniaux, en particulier celles prévues aux articles 217 , 219 , 1426 et 1429 ou, par une autre mesure de protection moins contraignante.” A judge must therefore check first whether the family’s English LPA, the spouses’ mutual powers, or a lighter measure would do — which is why your refused LPA file, far from being wasted, becomes exhibit one in the guardianship application. The same article adds proportionality: “La mesure est proportionnée et individualisée en fonction du degré d’altération des facultés personnelles de l’intéressé.” Between spouses, two older provisions often do the quiet work: Article 217 of the civil code, word for word — “Un époux peut être autorisé par justice à passer seul un acte pour lequel le concours ou le consentement de son conjoint serait nécessaire, si celui-ci est hors d’état de manifester sa volonté ou si son refus n’est pas justifié par l’intérêt de la famille” — and Article 219 of the civil code — “Si l’un des époux se trouve hors d’état de manifester sa volonté, l’autre peut se faire habiliter par justice à le représenter, d’une manière générale, ou pour certains actes particuliers, dans l’exercice des pouvoirs résultant du régime matrimonial, les conditions et l’étendue de cette représentation étant fixées par le juge.” Where the blocked act is the sale of the jointly owned matrimonial home and the couple married under a community regime, these spousal powers can unlock the file without any guardianship at all — a point worth raising with your lawyer before applying for heavier measures.

Two rulings show how judges police these routes in practice. On mandates, the First Civil Chamber held on 17 April 2019 (appeal no. 18-14.250, reported in the Bulletin, Court of Cassation, First Civil Chamber, 17 April 2019, no. 18-14.250) that “il résulte de l’article 483, 4°, du code civil que la révocation du mandat de protection future peut être prononcée par le juge des tutelles lorsque son exécution est de nature à porter atteinte aux intérêts du mandant”, adding that “aux termes de l’article 485, alinéa 1, du même code, le juge qui met fin au mandat peut ouvrir une mesure de protection juridique”. The statute behind that holding is worth reading directly: Article 483 of the civil code lists among the endings of an activated mandate “Sa révocation prononcée par le juge des tutelles à la demande de tout intéressé, lorsqu’il s’avère que les conditions prévues par l’article 425 ne sont pas réunies, ou lorsque l’exécution du mandat est de nature à porter atteinte aux intérêts du mandant.” In that case the agent had filed a late and incomplete inventory, omitted wealth-tax returns triggering a tax reassessment, and left spending unexplained — and the court replaced the mandate with reinforced curatelle. The lesson for attorneys under an English LPA is symmetrical: keep an inventory from day one, file tax returns on time, and keep receipts, because the same failures that sank that French mandate will sink your credibility before a French judge. On procedure, the First Civil Chamber recalled on 2 March 2022 (appeal no. 20-19.767, reported in the Bulletin, Court of Cassation, First Civil Chamber, 2 March 2022, no. 20-19.767) that a judge may only strengthen an existing measure on a properly constituted application — and Article 431 of the civil code makes the price of admission explicit, word for word: “La demande est accompagnée, à peine d’irrecevabilité, d’un certificat circonstancié rédigé par un médecin choisi sur une liste établie par le procureur de la République.” No listed-doctor certificate, no case: that irrecevabilité (inadmissibility) rule defeats more applications than any debate on the merits. Families dividing over the choice of protector should also read Article 484 of the civil code, word for word: “Tout intéressé peut saisir le juge des tutelles aux fins de contester la mise en oeuvre du mandat ou de voir statuer sur les conditions et modalités de son exécution.” A sibling who distrusts the attorney need not attack the LPA in England; they can petition the French guardianship judge directly. And the bridge between routes is Article 485 of the civil code, word for word: “Le juge qui met fin au mandat peut ouvrir une mesure de protection juridique dans les conditions et selon les modalités prévues aux sections 1 à 4 du présent chapitre.” Refusal of the LPA is therefore never the end of the road: it is the factual trigger for the French measure that replaces it.

B. Papers, procedure, Paris practice and how to challenge a refusal

Open the right envelope with the right papers. For activation of a French mandat de protection future, the agent files the mandate and the listed doctor’s certificate at the greffe of the tribunal judiciaire of the protected person’s residence; the clerk endorses and dates it, and the mandate takes effect without a hearing. For habilitation familiale, tutelle or curatelle, a petition (requête, the written application to the judge) goes to the juge des tutelles of the same court, and it must contain, on pain of inadmissibility, the listed doctor’s certificate, the applicant’s identity and family record (livret de famille or English birth and marriage certificates with sworn translations), proof of residence, a description of the assets and income at stake, and — decisive in British files — the English LPA with its apostille and sworn translation, plus the bank’s or notaire‘s written refusal. Name the measure you seek and plead in the alternative: family authorisation as the primary request, curatelle or tutelle as the fallback, with reasons why the LPA alone cannot suffice. Where money is about to be lost — a sale falling through, a care-home bill unpaid, a tax deadline passing — say so on the first page and ask the judge to treat the file as urgent: the juge des tutelles can act quickly on a complete file and slowly on an incomplete one, and completeness is within your control.

Paris and Île-de-France practice deserves its own paragraph, because that is where many British files land. If the protected person lives in Paris, the competent court is the tribunal judiciaire de Paris, and the guardianship judge sits at the Batignolles complex; residents of the inner suburbs apply to the tribunal judiciaire of their département (Nanterre, Bobigny, Créteil and so on). The listed doctors (médecins inscrits, the practitioners registered with the public prosecutor) are departmental lists obtained from the court registry or the prosecutor’s office — book early, because the detailed certificate requires an actual examination and the waiting time in Paris commonly runs to several weeks. Practical delays overall: a straightforward habilitation familiale on a complete file typically takes two to four months from filing to order in the Paris region; a contested tutelle with family dispute or a large estate can take six months or more, with a hearing at which the protected person is heard unless the medical certificate states that attendance would harm their health. Procedural channel: the petition may be filed by the person themselves, a relative, the prosecutor, or, in some cases, the doctor or care establishment; representation by a lawyer (avocat, the qualified legal representative) is not always compulsory but is strongly advisable in cross-border files, because the judge will probe the English documents and the exact scope of the requested powers. Points of attention specific to the area: Paris notaires apply the strictest reading of foreign powers, so do not file a Paris sale on an LPA alone without warning your buyer of the likely timetable; Paris banks centralise succession and incapacity files in dedicated departments whose written requirements differ from branch advice, so always escalate from the branch to the central department and keep the written reply; and where the protected person splits time between London and Paris, fix the residence evidence carefully — French health cover, tax residence, the address on the taxe foncière — because jurisdiction follows habitual residence and a contested residence means months lost. Readers dealing with the parallel question of what happens to the French house on death should consult our companion guide on English wills, French houses and the choice of English law, which explains how the succession rules interact with the lifetime measures described here.

Refusals come in three kinds, and each has its remedy. First, the bank or notaire refuses the LPA for a curable reason — missing apostille, unsworn translation, uncertified copy. Cure it and re-present; most files end here, which is why the proof pack in Part I matters more than any argument. Second, the institution refuses on policy — “we do not act on foreign powers” — or simply never answers. That policy is not a court order and does not bind the guardianship judge; annex the refusal to your petition and ask for the French measure that replaces the LPA for the blocked act. Third, the judge refuses or grants less than you sought — for example family authorisation limited to one account where you asked for general powers, or rejection for an out-of-date certificate. The order of the juge des tutelles can be appealed to the full court (cour d’appel, the appeal court) within the statutory time stated on the notification, and any interested party can later return to the judge under Article 484 to contest how a mandate is being executed or to seek a different measure as circumstances change. Keep every deadline in a single diary: time limits on appeal run from notification, medical certificates go stale, and a refused petitioner who re-applies with a fresh certificate and the missing valuation often succeeds where the first attempt failed. Costs are modest — court fees for these applications are low, the medical certificate is charged at a regulated tariff, and the real expense is translation and legal advice — but delay is expensive, because a frozen account keeps charging care-home fees while nobody can move money.

Conclusion

Return to the daughter in London and the frozen Paris account. Her file succeeds if she works the decision tree in order. First, make the English LPA the best version of itself: registered instrument, correct apostille chain, sworn translation, solicitor’s capacity note, indexed proof pack, written answer from the bank’s central department rather than the branch. Many day-to-day mandates are accepted at this stage, and the file ends for the price of an apostille and a translation. Second, if the notaire still refuses the sale or the bank maintains a policy refusal, stop negotiating and petition the guardianship judge: family authorisation for the blocked act where one transaction is the whole problem, a French future mandate activated at the registry where the donor signed one in time, or tutelle or curatelle where the impairment is global and the estate needs full supervision. Third, use the English LPA inside the French proceedings as evidence of the donor’s wishes rather than as a weapon against the French institution: judges applying the subsidiarity rule expressly check what the mandate and the family already provide, and an attorney who arrives with clean accounts, filed tax returns and the refusal letters is granted powers that an attorney who arrives empty-handed is refused. The thread running through every stage is proof — medical proof of the impairment, documentary proof of the authority, written proof of the refusal — and the family that assembles it first controls the timetable instead of suffering it.
