When a British citizen living in France can no longer manage money, healthcare or daily decisions, the family often asks one urgent question: can a UK Lasting Power of Attorney (LPA) be used immediately in France, or must a French court appoint someone? The answer depends on the instrument, the decision required, the person’s habitual residence, the evidence of the medical change and the way a French bank, notaire or public body can verify the representative’s authority. Brexit did not turn every British mandate into an empty document, but it did make it unsafe to treat a UK form as a universal French power of representation.

This article addresses the person rather than the purchase of a French property or the creation of a company. It explains the difference between an English or Welsh LPA and the French protection regimes known as habilitation familiale (family authorisation), curatelle (assisted protection) and tutelle (representation-based protection). It also sets out the evidence to assemble when an account is frozen, care must be organised or a notarial transaction cannot wait. Scottish and Northern Irish instruments follow different systems, so the first task is always to identify where the UK document was made and registered.

The legal objective is not to remove the adult’s autonomy because a relative is worried. French law requires a medically established impairment, necessity and an individualised response. A family that sends a precise document pack and asks for a written reason for refusal will usually be in a stronger position than a family that repeatedly forwards an untranslated mandate. Where the person is at immediate risk, the request must combine protection of the person, preservation of essential funds and a procedure capable of producing an enforceable decision.

I. Can a British adult living in France rely on a UK LPA after losing capacity?

A. Can a UK Lasting Power of Attorney be used in France after Brexit?

An LPA is not a single all-purpose authority. In England and Wales, the official system distinguishes a property and financial affairs LPA from a health and welfare LPA. The first can concern bank accounts, pensions, bills, investments and property. The second concerns personal welfare decisions and can include certain medical or care decisions, subject to the document and the statutory limits. The GOV.UK LP12 guidance describes the document as an appointment of trusted people to make property, financial, health or welfare decisions. It also warns: “Your LPA is made under the law of England and Wales.”

That sentence is important for a British family in France. It identifies the legal origin of the mandate; it does not say that a French institution must accept every instruction without checking the document. A UK property and financial affairs LPA may help an attorney deal with a British pension provider or a UK bank while a French bank still asks for a certified copy, an apostille, a French translation, proof of registration and evidence that the authority covers the exact operation. A health and welfare LPA may be relevant to a UK provider without giving an attorney an automatic right to make every decision about treatment in a French hospital.

The word “attorney” also creates a translation risk. In the LPA, an attorney is the person appointed by the donor. In French correspondence, an avocat is a lawyer, while a mandataire is a person acting under a mandate. The French expression mandat de protection future means a future-protection mandate: a French instrument intended to organise representation if the person later cannot look after their own interests. It is not a translated version of an LPA. The French notaire is a public officer with functions that cannot simply be equated with those of a UK solicitor or notary public.

The first legal question is therefore classification, not apostille. Ask whether the British document is:

• a registered property and financial affairs LPA made in England or Wales;
• a registered health and welfare LPA;
• an older enduring power of attorney, meaning the pre-October 2007 instrument that may still operate under UK rules;
• an ordinary power of attorney that only operates while the donor retains capacity or under the document’s own limits; or
• a private letter, bank mandate, trust authority or solicitor’s certificate that does not itself create continuing incapacity representation.

Do not describe the fifth category as an LPA merely because a British adviser used the words “power of attorney”. A French recipient must be able to see the document, the registration evidence and the scope of the powers. The official GOV.UK power-of-attorney guidance confirms that a donor must have mental capacity when choosing an attorney and that there are separate forms for property and financial affairs and for health and welfare. If the donor has already lost the necessary capacity, the family cannot simply sign a new English and Welsh LPA on the donor’s behalf.

French law begins from the same concern for the individual. Article 415 of the French Civil Code states that “Les personnes majeures reçoivent la protection de leur personne et de leurs biens”. In context, protection must respect individual freedoms, fundamental rights and dignity, pursue the protected person’s interest and preserve autonomy as far as possible. A French court therefore does not appoint a representative merely because an adult is foreign, speaks English or owns assets in two countries.

The threshold is set by Article 425 of the French Civil Code. The person must be unable to look after their interests because of a medically established impairment of mental faculties or bodily faculties that prevents them expressing their will. The text says that the person “peut bénéficier d’une mesure de protection juridique prévue au présent chapitre”. That medical test is different from a family member’s general concern, a diagnosis without functional detail or a bank’s refusal to accept a document.

There is a second threshold: necessity and proportionality. Article 428 of the French Civil Code gives priority to less restrictive solutions, including an effective future-protection mandate, ordinary representation and matrimonial rules. It requires the measure to be proportionate and individualised. The phrase “La mesure est proportionnée et individualisée” is not decorative. It requires the application to explain which decisions cannot be made safely, which decisions remain possible and why the requested authority is no wider than the risk.

That is where the existing guide on UK powers of attorney in France must be placed in the analysis. If the document is valid, registered and sufficiently clear, it may be evidence that a new French judicial measure is unnecessary for some tasks. If it covers only UK assets, only financial decisions or only a person who remains capable of giving instructions, it may not solve the French problem. If a French recipient challenges the document, the family should not assume that the refusal itself proves the LPA is invalid. The family should ask which of four objections is being made: authenticity, language and formality; scope of the powers; continuing validity; or the need for a French decision for the act requested.

A cross-border mandate also requires care with the applicable law. In Cour de cassation, First Civil Chamber, 27 January 2021, no. 19-15.059, the court considered a foreign incapacity mandate under the Hague Convention on the International Protection of Adults. The decision concerned a Swiss mandate, not a UK LPA, and must not be presented as an automatic answer for British documents. It nevertheless records a useful principle: “elle ne saurait être subordonnée à des conditions propres au droit français”. In other words, a foreign mandate cannot necessarily be rejected merely because it lacks a control feature required by French domestic law if the law governing that mandate does not require it.

The practical consequence is a targeted legal review. Identify the donor’s habitual residence when the document was signed, the document’s governing law, the country in which it was registered, the place where the attorney needs to act, and the nature of the decision. A French court may need to determine the effect of the foreign mandate, while a British institution may still require the attorney to use the UK access code or obtain a certified LPA summary. The two systems can operate in parallel. One certificate cannot be assumed to replace the other.

Finally, death ends the lifetime problem and begins a succession problem. An attorney does not become an executor or heir merely because the donor appointed them during life. A frozen French account after death may require a notary, heirship evidence or an executor’s authority. That is a different file from incapacity, and mixing the two can lead a bank to reject an otherwise well-prepared request.

B. When should a British family ask for French guardianship instead?

“French guardianship” is a convenient English description, but French law offers several different measures. Curatelle is an assisted regime: the adult generally remains able to act, but needs continuing assistance or control for important civil acts. Tutelle is a representation-based regime: a tuteur, meaning the appointed representative, acts for the person in civil matters within the limits set by law and the judgment. Habilitation familiale is a family authorisation that can allow a close relative to assist or represent the adult for specified acts or, if justified, more broadly. Sauvegarde de justice, meaning judicial protection, is a temporary and lighter measure that may include a special mandate for an urgent act.

The boundary between curatelle and tutelle is stated in Article 440 of the French Civil Code. It describes curatelle for a person who is not unable to act but needs continuing assistance or control for important civil acts. It adds: “La curatelle n’est prononcée que s’il est établi que la sauvegarde de justice ne peut assurer une protection suffisante.” Tutelle is reserved for a person who must be represented continuously, and it is used only if neither judicial protection nor curatelle is sufficient.

That sequence matters for a British resident who can still make some decisions in English or with support. A bank account problem does not automatically justify tutelle. A physical impairment that prevents signing but leaves understanding intact does not automatically justify representation for all affairs. The application should describe the decisions, the functional difficulty and the safeguards requested. It should address whether a trusted relative can assist, whether a limited mandate is enough and whether the issue concerns only France or also British institutions.

The person’s voice remains central. Article 432 of the French Civil Code provides that the judge decides with the person heard or called, and that “L’intéressé peut être accompagné par un avocat”. The judge may dispense with the hearing only by a specially reasoned decision and on medical advice in the circumstances defined by the text. An English-speaking adult should be able to explain their wishes; the family should request appropriate interpretation or assistance where language prevents meaningful participation.

Personal decisions are not automatically transferred to a representative. Article 459 of the French Civil Code says that, outside strictly personal acts, “la personne protégée prend seule les décisions relatives à sa personne dans la mesure où son état le permet”. If the person cannot make an informed personal decision, the judge can organise assistance and, in limited circumstances, representation. A relative cannot use a financial LPA as a licence to make personal medical, residential or family choices that the document and French law do not cover.

Habilitation familiale can be attractive when the family is close, agrees on the person to be appointed and needs a practical authority in France. Article 494-1 of the French Civil Code allows the judge to authorise an ascendant, descendant, sibling, spouse, civil-solidarity partner or cohabiting partner to assist or represent the adult where a medically established impairment prevents the adult from looking after their interests. The appointed person acts without remuneration. The French term ascendant means a parent or grandparent; descendant means a child or grandchild.

It is not a shortcut around every existing authority. Article 494-2 of the French Civil Code provides that “L’habilitation familiale ne peut être ordonnée par le juge qu’en cas de nécessité”. The judge must consider ordinary representation, the rights and duties of spouses, matrimonial-property rules and an existing future-protection mandate. A British family should therefore attach the LPA, even when it thinks the LPA is inadequate. Showing the court why the LPA cannot be used for a particular French act is stronger than omitting it and leaving the court to suspect that a workable solution has been ignored.

The scope must be drafted with precision. The official Code section on habilitation familiale states that it may cover one or more acts concerning the adult’s property or person, and that a general authorisation has a maximum initial duration of ten years, subject to the statutory renewal rules. The relevant provision is Articles 494-1 to 494-12 of the French Civil Code. A request should say, for example, whether the relative needs to receive UK pension payments, manage a French bank account, sign a care contract, deal with the tax administration or instruct a notaire. “All my affairs” may invite further questions where a defined list would answer them.

An application may be unsuitable if the family is divided or the proposed representative has a conflict of interest. The judge can prefer curatelle or tutelle, appoint a professional judicial representative or limit the authorisation to an act. A relative who wants to sell an asset for their own benefit, transfer money to themselves or decide a succession dispute should expect a higher level of scrutiny. The adult’s British nationality does not remove those safeguards; it makes the evidence and translation more important.

The place of residence usually determines the French court route. Article 1211 of the Code of Civil Procedure states: “Le juge des tutelles territorialement compétent est celui de la résidence habituelle”. A British person who owns a house in France but habitually lives in England may present a different jurisdictional question from a British person who lives, receives care and has their daily centre of life in France. The address on a residence permit is useful evidence, but the court will examine the real circumstances.

The family should not wait for a bank to decide that it has no one to deal with. If rent, care fees, insurance, tax or food expenses cannot be paid, ask the court and the relevant institution what temporary proof can be accepted. A French bank may be able to preserve the account while it verifies the representative; it may also require a court order for operations outside ordinary administration. The request should explain the immediate consequence of inaction and attach the invoice, deadline or care requirement that makes the urgency concrete.

For a British adult who has not yet lost capacity, prevention remains possible. A UK LPA can be reviewed with French use in mind, and a French mandat de protection future can be considered before a crisis. Under Article 477 of the French Civil Code, a qualifying adult can appoint one or more people to represent them if they later cannot look after their interests. The French form, execution method, activation evidence and scope should be discussed before signing. It is not prudent to wait until a diagnosis, hospital admission or blocked account makes a new mandate impossible.

II. What should the family do when a French institution refuses the authority?

A. What documents and urgent safeguards should the family prepare?

The best first response is an indexed cross-border file. Its purpose is to let the recipient answer five questions without guessing: who is the adult, who is asking to act, what document creates the authority, what exact act is requested and why the authority is still effective. The file should be prepared in English for the family’s records and in French for the recipient when a French translation is required. Keep the two versions aligned; a translation that shortens a limitation or omits an annex can create a more serious problem than no translation at all.

For the UK document, collect the complete registered LPA or the official summary, every continuation sheet, the registration date, the donor’s identity details, the attorney’s details, replacement-attorney provisions, instructions and preferences, and any evidence about when the attorney may act. The GOV.UK LPA checking service explains that an access code can allow an organisation to view a summary showing whether an LPA is registered, who the attorneys are, how they act and what restrictions apply. A French institution may not be able to use the UK service itself, so provide a clear certified copy and an explanatory note.

Then identify the French formalities. A French recipient may ask for an apostille, which authenticates the origin of a public document, and a French translation by a qualified translator. An apostille does not prove that the donor understood the document, that the attorney’s power is wide enough or that a transaction is in the donor’s interest. If a private document was certified before apostille, keep the underlying certification and the apostille together. If the recipient asks for a recent copy, ask it to state how recent and why, rather than assuming an old document has become legally void.

Prepare a one-page authority map. It should contain columns for the French institution, the requested act, the document clause relied on, the French legal measure if any, the person who will sign, the deadline and the evidence of delivery. This is particularly useful when the British attorney is dealing with several organisations. A French bank may need to release funds for care, while a pension administrator may need to update payment instructions and a notaire may need an authority for a separate transaction. One institution’s acceptance does not bind another institution.

If a French judicial measure is needed, the medical evidence must describe function rather than merely name a condition. Article 1218 of the Code of Civil Procedure makes the certified medical report a condition of the application and requires the identity of the person and the facts calling for protection. It uses the phrase “à peine d’irrecevabilité”, meaning that an application can be rejected as inadmissible if the required element is missing. The report should explain what the adult can and cannot do, how the impairment affects decisions, whether it is expected to improve and whether a hearing could endanger health or is impossible.

The application should also provide the family, social, financial and asset context. Article 1218-1 of the Code of Civil Procedure requires the request to identify people in the adult’s circle and, where possible, the treating doctor and the adult’s family, social, financial and property situation. For a British resident, that means explaining UK and French addresses, spouse or partner, children and siblings, care arrangements, pension sources, bank accounts, insurance, property, tax correspondence and any existing UK or French mandate. It also means disclosing disagreement rather than presenting a one-sided family story.

Translate the medical and civil-status evidence carefully. A French judge may need an original or certified birth certificate, proof of address, identity documents, proof of the family relationship, the registered LPA, the UK registration evidence and a French medical certificate. “Certified translation” is not a single universal label: ask the court registry or the receiving institution what translator status and certification it accepts. A translated diagnosis should preserve dates, limitations and reservations. Do not ask a translator to give a legal conclusion about whether an LPA is valid in France.

Urgency should be demonstrated with dates and consequences. Include a care-home invoice, a notice of unpaid rent, a threatened utility suspension, a scheduled medical decision, a pension-payment interruption, a tax deadline, a bank letter or a notarial completion date. State what will happen if no authorised person can act. A general sentence such as “the family is worried” is less useful than “the French account is the only account from which the care invoice due on 5 September can be paid, and the bank has suspended online access pending proof of representation”.

Protect the adult’s money while the authority is being resolved. Do not transfer funds to a relative’s personal account, mix the adult’s money with family money or use a joint account to avoid the verification process. Keep a separate ledger of payments, receipts and decisions. A person appointed under a French measure must act in the adult’s interest and within the judgment. A UK attorney is likewise expected to act within the LPA and in the donor’s best interests. A transparent ledger helps the bank, court and family distinguish necessary expenditure from an allegation of misuse.

Do not overstate a French judgment. Article 473 of the French Civil Code says that, subject to legal or customary exceptions, “le tuteur la représente dans tous les actes de la vie civile”. That gives a tutelle representative a broad role in civil acts, but it does not erase special authorisation requirements, strictly personal acts, conflict rules or the limits recorded in the judgment. A bank should receive the full judgment and the appointment certificate, not only a relative’s statement that they are “the guardian”.

Housing and personal life need separate treatment. A relative who can pay a French care bill may not be able to decide alone that the adult’s home should be sold, that a lease should be terminated or that all personal correspondence should be redirected. Explain whether the adult’s home remains available, whether care is temporary or permanent and whether a sale is truly necessary. If the operation is a property purchase or sale, the transaction follows its own notarial process; this article does not replace the property desk’s purchase guidance. The incapacity question and the real-estate transaction should be connected but not confused.

Where there is a risk of exploitation, preserve evidence before making accusations. Save bank statements, emails, messages, call notes, unusual withdrawals, powers of attorney, medical observations and delivery receipts. Ask the bank to flag suspected unauthorised instructions and to preserve the relevant records. If an attorney is suspected of abusing the LPA, the family may need to contact the Office of the Public Guardian for UK-side issues and seek French legal protection for French assets. A judicial application can ask for a different representative or a narrower measure where the proposed representative has a conflict.

B. How can you challenge a refusal by a French bank, notary or authority?

Begin by turning the refusal into an identifiable decision. Ask for the response in writing and request the precise missing item: an apostille, a complete LPA, a French translation, a medical certificate, proof of registration, a court order, a more specific clause, identity evidence or an anti-money-laundering document. A telephone statement that “the UK document is not accepted after Brexit” is not enough to know whether the real objection is legal, operational or compliance-related. Record the date, department, name of the person contacted and the deadline affected.

Separate the institution’s role from the court’s role. A bank may reasonably refuse to execute an irreversible transfer while it verifies authority. A notaire may need to confirm that the person signing has power for the exact deed. A public body may require its own representative-registration procedure. None of those internal checks automatically decides whether the LPA is valid under its governing law. Conversely, a family should not accuse the institution of unlawful discrimination merely because it asks for a document a French institution cannot read or verify.

The French case law on mandates supports a document-first response. In Cour de cassation, First Civil Chamber, 28 September 2022, no. 20-21.631, the court stated that “une personne peut être engagée sur le fondement d’un mandat apparent lorsque la croyance du tiers aux pouvoirs du prétendu mandataire a été légitime”. The case concerned the circumstances in which a third party could rely on apparent authority. It does not give a British attorney a free-standing power, but it shows why the circumstances, the notarial involvement and the apparent scope of the mandate may matter.

The opposite lesson is equally important: do not rely on a title or an unexplained reference in another deed. In Cour de cassation, First Civil Chamber, 24 April 2013, no. 11-27.082, the court examined a challenge to a power of attorney and stated that “le juge doit s’assurer de l’existence et de la régularité du mandat habilitant le tiers à conclure l’acte au nom et pour le compte de la partie absente”. The exact factual setting was different, but the procedural message is directly useful: produce the mandate itself, its limits and the evidence that the representative’s act falls within those limits.

For a foreign incapacity mandate, the 2021 decision in no. 19-15.059 also cautions against importing every French formality into a foreign instrument. The result is not that a recipient must accept an unverified document. It is that the family should identify the rule governing validity and the rule governing exercise. Ask whether the refusal concerns the mandate’s creation, its activation, the representative’s power for a specific act or the form of evidence demanded in France. Those questions may lead to different remedies.

If a decision of the French judge of protection is needed, use the application route rather than asking a bank to invent a temporary guardianship. The French expression juge des contentieux de la protection means the judge of the court responsible for protection and certain related civil matters; older documents may call the function the juge des tutelles, the guardianship judge. File with the competent court based on habitual residence and request the precise measure: limited habilitation, assistance, representation, temporary protection or authorisation for a defined act. Include a proposed order or a clear schedule of powers where that helps the court understand the practical need.

For a curatelle or tutelle dispute, the adult must be kept in the process. The person can be assisted by a lawyer, and the family should arrange communication in a language the adult understands. A relative cannot turn the hearing into a contest about who deserves control of the money. The court’s question is which arrangement protects the person while respecting autonomy. If the adult can manage a small account, communicate care preferences or decide where to live, those facts should be recorded even if a representative is needed for a major transfer.

For habilitation familiale, check the family-consent and conflict position. The court will examine the proposed person, the scope and the adult’s interest. If one sibling objects, if the spouse and children disagree or if the proposed representative is a beneficiary of the transaction, explain the conflict and ask for a regime with appropriate oversight. An authorisation that is easy to obtain but impossible to defend later can expose the family and the adult to a second dispute. A narrower authority with clear reporting may be safer than a general authority resting on informal trust.

An appeal or challenge must be matched to the document being contested. A bank’s internal refusal, a notaire’s decision not to receive an act, a court order opening a protection measure and a UK Office of the Public Guardian decision do not follow the same route or deadline. Do not send one generic “appeal” to all four. Identify the issuing body, the date of notification, the legal basis stated, the remedy mentioned and the practical harm. Preserve the envelope, email headers, portal screenshot and proof of submission. If the notice gives a short deadline, obtain advice before waiting for a mediation response.

A French institution may offer a complaint or mediation process, especially for banking services, but mediation does not create a representative’s authority and does not necessarily suspend a judicial deadline. Use it to ask for review of a documentary refusal while preparing the court route if funds, care or a transaction are at risk. A written complaint should attach the corrected pack, quote the exact refusal and ask for a final position. If the bank accepts the LPA after review, ask for written confirmation of the operations that remain restricted.

Cross-border coordination is often the decisive step. Ask the British attorney to obtain the official LPA summary and confirm registration with the Office of the Public Guardian. Ask the French lawyer or court registry what copy, translation and medical evidence are required. Ask the French bank or notaire what operation is blocked and whether a court order or an additional deed would cure the problem. Ask the care provider, pension payer and tax authority which person they will recognise. Put the answers in the authority map, with one owner and one deadline for each task.

When the LPA is insufficient, do not create an informal substitute. A spouse should not sign as “guardian” without a French judgment; a child should not use the adult’s card because the bank has frozen the online account; and a UK attorney should not assume that an LPA for property and financial affairs authorises a French notarial act requiring a more specific power. If a decision cannot wait, ask the competent French court about the urgent measure available on the evidence, while preserving the adult’s funds and personal wishes in the meantime.

A later French judgment may also need to be shown to a British institution. Prepare an English explanatory translation, the certified copy, the appointment details, the scope of the order and the date from which it operates. The French measure does not automatically replace the UK LPA for UK assets. Conversely, a UK LPA does not automatically replace a French appointment for French acts. Each institution should be given the instrument that its own system can verify, together with an explanation of how the two documents fit together.

One final case-law point prevents overconfidence. The 6 March 2024 decision in Cour de cassation, First Civil Chamber, no. 22-12.911 arose from a dispute about a Swiss incapacity mandate and the effect of a prior appellate decision. It does not decide the status of a UK LPA, but it illustrates the need to identify the exact judgment, its operative part and the procedural stage before telling a bank that “the court has recognised the mandate”. A citation without its holding, date and scope can mislead the recipient and weaken the file.

The response should end with a decision tree written in ordinary language. If the British document is valid and covers the act, submit the complete certified pack and request written confirmation. If it is valid but too narrow, ask for the additional French or UK authority that the act requires. If the adult has lost capacity and no workable mandate exists, file for the least restrictive French measure supported by the medical evidence. If there is an immediate risk to housing, care or funds, document the urgency and ask for a limited protective response. If there is suspected abuse, preserve evidence and seek a change of representative or a protective order.

Conclusion

A British adult living in France does not become unprotected because a UK LPA meets a French institution. Nor does a UK LPA automatically answer every French question after Brexit. The decisive issues are the document’s legal origin, its registration and continuing effect, the precise power requested, the adult’s habitual residence, the medically established functional impairment and the proportionality of any French measure.

Start with the complete LPA and its UK evidence, then obtain the formalities and translation required by the French recipient. If the mandate is insufficient, compare habilitation familiale, curatelle, tutelle or a temporary measure under the French Civil Code. Use the court route when a judicial appointment is required, preserve the adult’s autonomy and wishes, keep the adult’s money separate, and demand a written reason whenever a bank, notaire or authority refuses to act. A precise authority map and a dated evidence file can prevent a documentary problem from becoming a care or financial crisis.
