A French assurance-vie is a life-insurance and investment contract whose death benefit may be paid directly to a named beneficiary. For a British beneficiary living in the United Kingdom, the difficult part is rarely the existence of Brexit itself. The real issues are usually the wording of the clause bénéficiaire (beneficiary clause), the evidence proving identity and entitlement, the French payment timetable, and the tax position in France and the United Kingdom.

A French insurer may ask for a death certificate, proof of the family relationship, certified translations, bank information, a tax form or a notarial document before releasing the funds. A request for documents is not automatically a lawful refusal. Conversely, a beneficiary should not assume that a policy is outside the estate, that a British will controls the clause, or that payment in euros has no UK inheritance-tax consequence.

This guide explains how a British beneficiary can identify the contract, assemble the claim, calculate the French tax route and challenge a refusal or delay. It covers the legal rules that apply after Brexit, the 15-day and one-month payment stages, the longer limitation period for a beneficiary, disputes about a changed clause, and the evidence needed when heirs allege that premiums were excessive. The facts of the policy, the date of the payments, the tax residence of the insured and the beneficiary, and the precise refusal letter remain decisive.

I. Can a British beneficiary claim a French life-insurance payout after Brexit?

A. What do the beneficiary clause and French succession rules mean?

The starting point is the policy, not the passport. The French expression assurance-vie covers contracts that can combine savings during the insured person’s lifetime with a capital payment on death. The person who signs the contract is commonly the souscripteur (policyholder). The person whose death triggers the payment is the assuré (insured person). The person entitled to the death benefit is the bénéficiaire (beneficiary). One person can hold more than one of these roles, but they must be identified separately when a dispute arises.

The beneficiary clause can name a person, several people, a spouse, children, heirs or a category of persons. Article L. 132-8 of the French Insurance Code states that the capital may be payable to “un ou plusieurs bénéficiaires déterminés” and also recognises a clause that defines people sufficiently for them to be identified when the benefit becomes payable. The full Article L. 132-8 of the French Insurance Code is therefore the first document to read. A phrase such as “my children”, “my heirs” or “my spouse” can have a legal effect different from a named individual.

That wording matters after Brexit because a British family may have a French policy, a UK will, a French notary and relatives in several countries. The fact that a beneficiary lives in England, Wales, Scotland or Northern Ireland does not, by itself, cancel a valid clause. Nor does the fact that the deceased was British make the policy automatically subject to the ordinary administration of the UK estate. The policy, the beneficiary clause and the relevant succession rules must be read together.

French law gives the policy a distinct position at death. Article L. 132-12 provides that capital or an annuity payable to a named beneficiary is not part of the insured’s succession. The statute uses the words “ne font pas partie de la succession de l’assuré”. That does not mean that every life-insurance payment is immune from every challenge. The clause may be invalid, the beneficiary may be unable to prove entitlement, premiums may be challenged as manifestly excessive, or tax rules may bring some amounts into a separate calculation.

The practical consequence is that a British beneficiary should keep two files. The first is the claim file: the policy, the clause, the death certificate, identity documents and correspondence with the insurer. The second is the estate and tax file: the will, family-status documents, the deceased’s French and UK tax residence, the premiums, the value of the policy and any claim made by heirs. Combining the files too early can create confusion. An heir’s disagreement about the estate does not necessarily give the insurer a reason to withhold an undisputed benefit.

Acceptance of the beneficiary clause is a separate issue. In French law, acceptation means that the named beneficiary has accepted the designation in the legally recognised manner. Article L. 132-9 says that the designation “devient irrévocable par l’acceptation de celui-ci”. Before the insured’s death, acceptance is ordinarily documented by an amendment signed by the insurer, policyholder and beneficiary, or by an act signed by the policyholder and beneficiary and notified to the insurer. After death, acceptance is free. The current Article L. 132-9 should be checked against the actual document rather than a family recollection.

Irrevocability can affect the policyholder’s ability to surrender the contract, take an advance or replace the beneficiary during life. It does not turn every later document into a valid payment instruction. The insurer should be asked for the version of the clause held in its records at the date of death, every amendment, the date it was received, and any record of acceptance. If the insurer refuses to provide those documents, the request should be repeated in writing with a clear explanation of why they are necessary to establish the claim.

A change made shortly before death requires particular care. In Cour de cassation, Second Civil Chamber, 3 April 2025, appeal no. 23-13.803, the Court held that the substitution of a beneficiary is not subject to a fixed form and that its validity depends on the policyholder’s will being expressed in a certain and unequivocal way. The decision states: “la substitution du bénéficiaire d’un contrat d’assurance sur la vie, qui n’est subordonnée à aucune règle de forme, suppose seulement, pour sa validité, que la volonté du contractant soit exprimée d’une manière certaine et non équivoque”. The Court also treated the insurer’s knowledge before death as a question of opposability, not an automatic condition of validity.

This 2025 ruling is important when an insurer says that a beneficiary change was ineffective only because the insurer received the document after the death. The issue is now more precise: was the policyholder’s intention certain and unequivocal, and what payment did the insurer make in good faith before the change was known? A beneficiary or heir should not rely on a short email alone. Collect the original amendment, the covering letter, handwriting or signature evidence, medical and care records where relevant, witness evidence, the policyholder’s instructions and the chronology of transmission.

An earlier decision shows why the evidence still matters. In Cour de cassation, First Civil Chamber, 5 April 2023, appeal no. 21-12.875, the Court required the lower court to examine the surrounding circumstances of signed amendments. Its wording was that the change could be made up to death “dès lors que sa volonté est exprimée d’une manière certaine et non équivoque”. The point for a British claimant is practical: if the clause is disputed, a certified translation of the document is only one part of the proof. The surrounding evidence can be just as important.

Brexit may also affect the route by which a UK will or civil-status document is understood in France. A will may determine succession rights without being the document that creates the policy benefit. A grant of probate may help establish the personal representative’s authority, but it does not automatically replace the beneficiary clause. A French notary may request an acte de notoriété, meaning a notarial deed identifying the persons entitled in a succession, where the clause refers to heirs or where the insurer needs to understand the family structure. The beneficiary should ask what legal question the document is intended to answer.

If no beneficiary can be identified, the insurer may transfer or handle the funds under a different process. A British relative who merely suspects that a deceased person held a French policy can use the Service-Public procedure for finding a life-insurance beneficiary and the AGIRA search. AGIRA is the French organisation that coordinates searches for certain insurance contracts after death. A person who already knows that they are the beneficiary should contact the insurer directly and keep proof of the date on which the insurer received the notification of death and the claimant’s contact details.

B. Which documents, identity checks and tax papers must a UK beneficiary send?

A claim should be sent as a complete, indexed pack rather than a succession of unconnected attachments. The first page should identify the deceased, the policy number, the beneficiary’s full name as written in the clause, the date of death, the address for correspondence and the requested payment account. Use the same spelling in the passport, death certificate, beneficiary clause, bank account and covering letter. If a surname changed after marriage or divorce, attach the civil-status documents linking the names.

The usual pack includes:

• the official death certificate, preferably the full version where the insurer or notary needs the parents, spouse or place of death;
• the policy schedule, general terms, latest statement and every beneficiary amendment available to the claimant;
• the beneficiary’s passport or national identity document, proof of address and, where requested, a recent bank statement;
• the document proving the relationship or category used in the clause, such as a birth certificate, marriage certificate, adoption order or evidence of descent;
• the beneficiary’s bank details, usually an IBAN and BIC, with an explanation if the account is in pounds rather than euros;
• the French tax form requested for the death benefit, commonly a partial succession declaration when the payment falls within a French tax regime;
• the contact details of the French notary or UK executor where the insurer needs to coordinate estate information;
• any document showing the deceased’s French tax residence, UK residence history, or the beneficiary’s French residence history when the tax rule depends on residence;
• a certified French translation of an English document when the insurer, tax office, notary or court has expressly required it; and
• an apostille or other legalisation only where the receiving body requires it for that document and purpose.

An apostille is not a universal solution to a missing document. It authenticates the origin of a public document for use abroad; it does not prove that the beneficiary clause is valid or that a tax calculation is correct. The UK government’s official legalisation and apostille service explains how to apply for a paper apostille or an e-Apostille. Before paying for one, ask the insurer or notary to confirm in writing whether it is required, whether a certified copy is acceptable, and whether a translation must be attached to the apostilled document.

The insurer’s anti-money-laundering checks can be strict for an overseas beneficiary. A request for the source of the bank account, a tax identification number, a telephone interview or a declaration of political exposure does not necessarily indicate that the claim is rejected. The response should be prompt and documented. Send sensitive documents through the insurer’s secure channel where available, retain the upload receipt and request confirmation that the pack is complete.

The tax question must be separated from the payment question. French law has different regimes depending on the date of the contract, the date and age at which premiums were paid, the identity of the beneficiary and the tax residence of the insured and beneficiary. Article 757 B of the French General Tax Code deals with sums linked to premiums paid after the insured reached 70. The current text refers to “primes versées après l’âge de soixante-dix ans” and provides an “abattement global de 30 500 €” across the relevant contracts of the same insured. This is a global allowance, not automatically €30,500 for every policy or every beneficiary.

Where Article 757 B does not apply, Article 990 I of the French General Tax Code can impose a separate levy on qualifying death benefits. The current text refers to an “abattement fixe de 152 500 €” for each beneficiary and sets rates of 20% up to the statutory threshold and 31.25% above it, subject to the conditions and exclusions in the article. The official Article 990 I of the French General Tax Code must be read in full because the text contains rules for contracts, exemptions, residence and special products.

For a British beneficiary, residence can be decisive. The text of Article 990 I includes a rule based on the beneficiary’s French tax domicile and six years of French domicile during the preceding 10 years, and a separate rule based on the insured’s French tax domicile at death. The French tax authority’s guidance for a life-insurance beneficiary explains the partial succession declaration and the residence situations that affect the relevant French service. An English claimant should not decide that no French declaration is needed simply because the payment is made to a UK account.

The United Kingdom may apply its own inheritance-tax analysis. HM Revenue & Customs now refers to a long-term UK residence test for foreign assets after 6 April 2025. The GOV.UK guidance on inheritance tax for a long-term UK resident explains that a person can remain within the UK inheritance-tax framework for a period after leaving the United Kingdom. The GOV.UK guidance for a person based outside the UK also recognises that a double-taxation treaty may provide a credit or repayment route where the same assets are taxed in two countries.

The beneficiary is not normally the person who calculates the deceased’s entire UK estate, but the beneficiary should provide the policy statement and French tax evidence to the executor. The policy’s death benefit, surrender value, ownership, trust status, premiums and beneficiary rights can affect the UK account. A payment that is outside the French civil succession may still need to be disclosed for UK inheritance-tax purposes. French and UK tax forms should therefore be prepared from the same date-of-death policy statement.

Use a document schedule with four columns: document, date requested, date sent and confirmation received. Add a fifth column for the person or institution responsible for any missing item. This simple schedule protects the beneficiary when the insurer says that the one-month payment period has not begun. It also exposes an unreasonable repeated request: if the same death certificate or identity document has already been accepted, ask why it is being requested again and which legal or compliance issue remains unresolved.

If a French insurer asks for a document that does not exist in the UK system, explain the difference rather than sending an informal substitute without context. For example, a UK executor may have a grant of probate while the French insurer asks for an acte de notoriété; the claimant can provide the grant, a certified translation and a letter explaining the executor’s authority, while asking the insurer whether a French notarial deed is still required. A UK civil partnership certificate, decree absolute or deed poll may also need a clear translation of its legal effect.

Keep the original English documents. The French translation should identify the translator and state whether it is certified. If the insurer accepts a scan, retain the high-resolution original and send the file name in the index. If a notary holds the originals, obtain a receipt. A lost original can cause a delay that later appears to be a beneficiary’s failure to cooperate.

Finally, ask the insurer to state whether it has accepted the claimant as beneficiary, whether it is still searching for another beneficiary, whether tax will be withheld or paid on the claimant’s behalf, and what exact item prevents payment. A refusal expressed only as “the file is under review” is not a sufficient explanation for a contested claim. The claimant needs a dated procedural position before deciding whether to complain, send a formal notice or issue proceedings.

II. How do you challenge a French insurer that refuses or delays payment?

A. Which deadline, notice and complaint preserve the claim?

French law separates the insurer’s document request from the payment deadline. Article L. 132-23-1 of the Insurance Code gives the insurer 15 days after receiving notice of death and learning the beneficiary’s contact details to request the documents needed for payment. Once those documents are received, the capital must be paid within a period that “ne peut excéder un mois”. The same Article L. 132-23-1 also limits repeated requests for identical or redundant documents.

The statute provides financial consequences for delay. After the first 15-day stage, the capital can bear interest at twice the legal rate for one month and then three times the legal rate. If the capital is still unpaid after the payment period, the unpaid capital can bear interest at twice the legal rate for two months and then three times the legal rate. The exact starting date must be calculated from proof of receipt, not from the date printed on the claimant’s letter. A claimant should preserve the postal tracking, secure-message receipt, email header, insurer acknowledgement and the date on which each requested document was supplied.

Service-Public summarises the same one-month payment rule in its page on finding a life-insurance beneficiary, but the policy and the statutory text remain important where a dispute concerns missing documents or the interest calculation. If the insurer says that the period has not started, ask for a table listing every item requested, the date it was requested, the date it was received and the reason the item is necessary. The claimant can then identify whether the alleged gap is genuine or whether the insurer is repeating a request already satisfied.

The first escalation is a written complaint to the claims department and the insurer’s complaints department. Use the policy number and a subject such as “Formal claim for death benefit — beneficiary resident in the United Kingdom”. State the date on which the insurer learned of the death, the date it learned the beneficiary’s details, the date the complete pack was delivered, the documents still disputed, the amount claimed and the statutory payment date. Request a written decision and the legal basis for any refusal.

If the insurer has not paid, send a mise en demeure, meaning a formal notice requiring performance by a specified date. It should not be an aggressive narrative. It should identify the contract, the beneficiary clause, the death, the documents delivered, the amount due, the payment account and the requested deadline. It should reserve the right to claim statutory interest, costs and any further loss. Send it by a method that proves receipt, and send a copy to the broker, the French notary and the relevant UK executor if they are involved.

A complaint to the insurer’s internal service and, where appropriate, the French insurance mediator can be useful, but it does not automatically suspend every limitation period. The claimant should continue to monitor the court deadline. A mediator may help when the insurer has not explained its document request or has misapplied the tax paperwork. It cannot decide a complex succession dispute with binding effect, and it may not be suitable where urgent protective proceedings are needed.

Article L. 114-1 of the Insurance Code sets a general two-year limitation period, but it extends the period for a life-insurance claim by a beneficiary who is distinct from the policyholder. The statute states: “La prescription est portée à dix ans” and also provides an outside period of 30 years from the insured’s death for a beneficiary’s action. The current Article L. 114-1 must be applied to the actual role of the claimant and the exact event giving rise to the claim.

Do not treat the 10-year period as permission to wait. The date of death, the date on which the beneficiary learned of the policy, any acknowledgement by the insurer, any partial payment and any formal proceedings can affect the calculation. A beneficiary who is outside France may also need time for translation, legalisation, evidence from a UK bank and instructions to a French lawyer. Obtain a limitation review as soon as the insurer refuses or stops responding.

The refusal letter should be classified before a remedy is chosen. Common categories are:

• identity refusal: the insurer says that the names, dates or civil-status documents do not match;
• clause refusal: the insurer says that the beneficiary wording is unclear, replaced or invalid;
• acceptance refusal: the insurer says that an earlier acceptance prevents a change or that the acceptance evidence is missing;
• tax refusal: the insurer will not release funds until a declaration, certificate or payment of French tax has been addressed;
• estate refusal: heirs or a notary claim that the premiums should be brought back into the succession;
• compliance delay: the insurer requests anti-money-laundering or bank evidence; and
• payment error: the insurer says it paid another person or cannot identify the correct beneficiary.

Each category requires a different response. A tax form does not prove that an heir has priority over a beneficiary. A dispute about excessive premiums does not automatically erase the clause. An identity mismatch may be solved by civil-status evidence, while a disputed amendment may require court evidence. The complaint should answer the insurer’s stated reason, not merely repeat that the claimant is British and named in a family will.

If the insurer has paid someone else, obtain the payment record and the clause on which the payment was based. The 2025 Court of cassation decision in appeal no. 23-13.803 recognised that a substitution can be valid even though the insurer did not know of it before death, while also addressing the protection of a good-faith payment. The claimant therefore needs the dates of the amendment, the insurer’s knowledge, the payment, the death and every communication. The remedy may be a claim against the recipient, the insurer, or both, depending on the facts.

A court application in France should be built around an exhibit bundle. Exhibit 1 should be the policy and clause; Exhibit 2 the death certificate; Exhibit 3 the beneficiary identity documents; Exhibit 4 the chronology; Exhibit 5 the insurer’s requests and responses; Exhibit 6 the complete submission proof; Exhibit 7 the tax documents; and later exhibits the formal notice, mediator response, expert evidence and calculation of interest. A bilingual index makes the file usable in a French court while allowing the British beneficiary to understand each document.

B. Can you contest an invalid beneficiary clause, exaggerated premiums or wrong tax treatment?

There are three common disputes after a refusal: the validity or interpretation of the beneficiary clause, the effect of an accepted or substituted beneficiary, and the challenge by heirs to the premiums. They are connected but not identical. A claimant should not concede that the policy forms part of the ordinary succession merely because the family is arguing about the amount of premiums.

Article L. 132-12 generally keeps the death benefit outside the succession when a beneficiary is determined. Article L. 132-13 adds a limit: the ordinary rules of bringing gifts into the succession or reducing gifts that infringe protected heirs do not apply to the capital, but the premiums can be examined where they were “manifestement exagérées eu égard à ses facultés”. In English, the question is whether the premiums were manifestly excessive in light of the policyholder’s means. It is not a simple test based on the size of the final payout.

The evidence is assessed at the time of each payment. Relevant facts can include the policyholder’s age, health, income, assets, debts, family responsibilities, expected needs, purpose of the investment, liquidity, surrender rights and the proportion of the estate placed into the policy. The claimant should gather bank statements, wealth statements, tax returns, property valuations, medical evidence where legally and proportionately available, the policyholder’s expenditure, the investment advice and the chronology of each premium.

In Cour de cassation, First Civil Chamber, 9 February 2022, appeal no. 20-18.544, a published decision, the Court confirmed that Article L. 132-13 did not apply to premiums paid into a life-insurance contract that the policyholder had already surrendered. It stated: “Ce texte ne s’applique pas aux primes versées sur un contrat d’assurance sur la vie racheté par son souscripteur.” The decision shows why the policy history, not only the last statement before death, must be obtained.

An heir who alleges excessive premiums must identify the payments, the financial facts at each date and the legal consequence sought. The claimant should ask whether the heir seeks a reduction, a report to the succession, a requalification as a gift, a declaration that a clause is ineffective, or repayment from a named beneficiary. Those claims have different evidence and limitation questions. A French insurer may continue to hold funds while it seeks a tax certificate, but it should not use a family allegation as a substitute for a reasoned legal position.

A clause dispute can involve the meaning of “my heirs”, a failed condition, a predeceased beneficiary, a typo, an unsigned amendment or a document received close to death. Article L. 132-8 recognises several ways to designate or substitute a beneficiary, and the 2025 ruling confirms that the statutory forms are not exhaustive. The central factual question is usually whether the policyholder’s intention can be established with certainty. The court may look at letters, emails, notes, witnesses, the drafting context and the policyholder’s conduct, while protecting against manufactured or ambiguous documents.

Acceptance can change the analysis. If a beneficiary validly accepted the designation before death, the policyholder may have lost the freedom to replace that beneficiary or surrender the policy without the beneficiary’s consent. Ask for the acceptance instrument, its date, its signatures and proof of notification to the insurer. If an alleged acceptance appears after death, Article L. 132-9 should be read carefully because the legal effect and the evidential issue are different.

The 2025 ruling also changed the way a delayed notification should be analysed. The insurer’s knowledge of the substitution is not automatically a validity condition. That does not mean that a claimant can disregard the insurer’s records. A payment made to a person who appeared entitled before the insurer knew of the change may be protected in some circumstances. A dispute must therefore address both the policyholder’s will and the insurer’s good faith at the time of payment.

Tax treatment can also be challenged, but the remedy depends on the error. If the insurer applies the wrong French levy, ask for the calculation showing the contract date, premium dates, insured’s age at each premium, allowance, rate and residence condition. If the beneficiary was charged when an exemption applied, submit the supporting residence or family documents to the insurer and the tax office. If the French tax declaration was filed incorrectly, a correction or claim may be needed. Do not ask the insurer to solve a UK inheritance-tax issue that belongs in the executor’s HMRC account.

The UK side deserves a separate check because an overseas life-insurance payout can be relevant to the deceased’s estate even where the French payment is made directly to the beneficiary. GOV.UK explains that Inheritance Tax is normally a tax on the estate and that a person who has left the UK can remain within the long-term residence rules for a period. The official overview of UK Inheritance Tax and the long-term-residence guidance should be read with the date-of-death rules in force for the relevant year. A UK tax adviser may also need to analyse trusts, pensions, gifts and the beneficiary’s own later income.

France and the UK do not necessarily tax the same legal base. France may assess a death benefit under Article 757 B or Article 990 I, while the UK may consider the policy under its estate rules or trust rules. The fact that French tax was withheld does not automatically prove that the UK tax return is complete. The executor should retain the French declaration, payment receipt and calculation. If both countries tax the same economic value, the treaty and domestic credit rules must be examined asset by asset.

When the insurer demands French tax clearance before payment, the beneficiary should respond without accepting an incorrect tax classification. Ask whether the insurer will pay the tax from the capital and remit the balance, whether the beneficiary must file a partial succession declaration, which French tax office is competent, and what document will release the funds. The official impots.gouv.fr guidance for a life-insurance beneficiary explains that a declaration may be required and that the insurer can be involved in the payment process. That administrative step is separate from a court’s decision about who owns the benefit.

A formal notice should claim the correct amount, but it should not guess at tax. State the gross capital as shown by the insurer, the amount already paid or withheld, the undisputed net sum and the sum reserved pending the tax calculation. If the claimant has not yet received the policy value, request a current statement and the value at death. If the insurer refuses to provide the calculation, ask the court for production of the policy file and a payment order where appropriate.

Urgency increases where the beneficiary is elderly, dependent on the funds, exposed to exchange-rate loss or facing a property or tax deadline. Evidence of financial need can support an application for prompt handling, but it does not replace proof of entitlement. The claimant should also avoid signing a full and final settlement, waiver or release without understanding whether it covers the gross capital, interest, tax, costs and any future challenge by heirs.

A British beneficiary should also check currency and bank-charge issues. The insurer’s obligation is usually expressed in euros. A transfer to a UK account can be reduced by intermediary-bank charges or an exchange-rate conversion, but those banking deductions do not necessarily reduce the contractual capital. Ask for the payment order, value date, gross amount, tax withheld, bank charges and net amount. If the insurer paid the wrong account, notify it and the bank immediately, preserve the fraud or payment report, and do not wait for the ordinary complaint timetable.

The legal strategy should be proportionate. A document clarification may resolve a compliance delay in days. A formal notice may be appropriate after a missed statutory payment period. Mediation can be useful for an unexplained calculation. A court application may be necessary where the clause, acceptance, excessive premiums or recipient identity is genuinely disputed. In every route, the beneficiary should preserve the limitation date, the proof of receipt and the official version of each French document.

Conclusion

A British beneficiary can have a valid claim to a French life-insurance death benefit after Brexit, but the claim must be proved through the policy, beneficiary clause, civil-status evidence and tax documents. The benefit may be outside the ordinary French succession while still being examined for excessive premiums, a disputed amendment or French and UK inheritance-tax purposes.

The immediate workflow is clear: notify the insurer, obtain the complete policy file, send an indexed bilingual claim pack, record the 15-day document stage and the one-month payment stage, request a reasoned refusal, and diarise the longer beneficiary limitation period without waiting for it to approach. If the clause or premiums are disputed, gather evidence from the date of each payment and analyse the current 2025 case law on beneficiary substitution.

Tax should be modelled separately in France and the United Kingdom, then compared under any applicable treaty or credit mechanism. A French tax declaration, an apostille, a UK probate document or a residence certificate may support the claim, but none of them alone determines the beneficiary’s civil entitlement. A refusal that remains unexplained after a complete submission should be escalated with a formal notice and, where necessary, proceedings in France.
