If you are a British spouse or partner living in France and a bank says that your joint account is frozen after the death of the other holder, check the account type and the written reason before accepting that answer. A French compte joint (joint bank account) is normally designed to let each cotitulaire (co-holder) operate it alone. The official French public-service guidance states that the account is not blocked when one co-holder dies, although the convention de compte (bank-account agreement) and the estate rules still matter. Access to the money is not the same as ownership of the balance. The deceased’s share may form part of the French estate, and a notary, the heirs or the bank may need proof of the source of funds, the family relationship and the authority to settle the estate.

For a British family, the cross-border element adds a second layer. A French bank account is not administered by simply applying the survivorship language used for a UK account. The date of death, the deceased’s last domicile, the marriage or civil-partnership position, the will, the children, the account agreement and the evidence of deposits must be placed on one timeline. A temporary compliance hold, a creditor’s seizure, an estate dispute and an ordinary request for succession documents are different events with different remedies. This article explains what should happen, which documents to send, how to protect the survivor’s own money and what to do if the bank, an heir or the notary continues to block the practical use of the account.

I. What happens to a French joint bank account when a British co-holder dies?

A. Is the account automatically blocked, and how much of the balance enters the estate?

The first question is whether the account really is a French joint account. The usual French wording is “Monsieur ou Madame”, or the names of several people joined by “ou”. Each named holder can ordinarily give payment instructions under the account agreement. That is different from a compte indivis, an account operated collectively, where the signatures of all holders may be required. It is also different from a sole account on which the survivor merely had a procuration, a power to act for the account holder. A power of attorney normally gives authority to operate another person’s account; it does not turn the agent into the owner of the money.

Service-Public’s current page on the French joint account says, in its section on death, that “En cas de décès d’un cotitulaire, le compte joint n’est pas bloqué”. The same official explanation says that the surviving co-holder can continue to operate the account, while the division of the money must be settled between the heirs according to the matrimonial regime or the relationship between the holders. That is the practical starting rule. It does not mean that every bank must permit every transaction without checking the death, the account agreement or a credible objection by the heirs.

The position is also reflected in Cour de cassation, commercial chamber, 3 November 2004, no. 01-10.675. The Court recorded that the death of a co-holder did not cause the account to be blocked or closed, that it could continue to operate under the signature of the surviving co-holder, and that the position changed in the event of “sauf opposition des héritiers du de cujus”. The expression de cujus means the deceased person. The decision is not a licence for the survivor to treat the whole balance as a personal gift. It explains why an automatic freeze of the entire French joint account is not the normal legal consequence of death.

Next identify the date at which the estate is measured. Article 720 of the French Civil Code states: “Les successions s’ouvrent par la mort, au dernier domicile du défunt.” In English, the succession opens on death, at the deceased’s last domicile. Take a statement showing the balance on that date, not only the balance on the day the bank finally responds. Preserve the transaction history for at least the period requested by the notary, including direct debits, pension payments, transfers made shortly before death, card payments and any cash withdrawals.

The account title alone does not decide who owned the money. A joint account may have been funded by both holders, by one holder, by a pension paid to one person, by rent from property owned by one person, or by proceeds from an inheritance. The bank may have owed both holders a payment facility while the internal ownership of the balance remained disputed. That is why a survivor should prepare a source-of-funds schedule: date, payer, sterling or euro amount, account from which the money came, purpose, and the document that proves it.

In a civil dispute, the ordinary working assumption may be that the balance is shared, but that assumption can be displaced by evidence. Cour de cassation, first civil chamber, 13 May 2014, no. 12-29.695, reproduces and approves reasoning that sums in a joint account are presumed to belong to the holders in undivided ownership by half, unless it is proved that the account was funded exclusively by one holder’s own money. The decision also refers to proof by all means. A survivor who contributed the whole balance should therefore keep payslips, pension statements, sale completion statements, inheritance papers and transfers from a personal account. An heir who says that every pound came from the deceased should preserve the contrary evidence rather than relying only on the account label.

There is a separate tax presumption. Cour de cassation, commercial chamber, 19 January 2010, no. 09-12.140, concerning Article 753 of the French General Tax Code, describes “la présomption simple de division par parts viriles”. That means a rebuttable presumption of equal shares for inheritance-tax purposes. The Court held that the tax authority could defeat the presumption by showing that the sums came exclusively from deposits made by the deceased. The tax analysis is not a complete substitute for the civil ownership analysis. It is, however, a warning that a half-share shown in a succession return may be challenged by either the administration or the beneficiaries when the account trail tells a different story.

Consider a simple illustration. A French joint account contains €80,000 at the date of death. The account was funded by €50,000 of the survivor’s documented pension savings and €30,000 of the deceased’s salary. A mechanical 50-50 calculation would put €40,000 in each person’s column. The evidence may support a different civil allocation, while the applicable succession and tax rules may still require a declared share of the deceased’s balance. The illustration is not a statutory formula. It shows why the survivor should not sign a family settlement, transfer the entire balance to a new account or accept a tax declaration before the source of each major credit has been reviewed.

Overdrafts require the same care. Joint-account holders are commonly jointly liable to the bank under the account agreement. If the account was overdrawn, the bank may be entitled to ask the survivor to regularise the account even if the underlying spending was made by the deceased. That question is distinct from the final allocation between the survivor and the estate. Pay or ring-fence any undisputed amount, but ask for the statement, the contractual basis and the date on which each debit arose. Do not sign an admission that the survivor personally owes every disputed transaction merely to obtain a copy of the account history.

A bank message saying “the account is frozen” can also conceal several different situations. The bank may have stopped online access while it verifies the death certificate; it may have blocked only transactions requiring a new mandate; it may have placed a fraud or anti-money-laundering hold; it may be responding to a formal opposition by an heir; or it may have confused the joint account with a sole account. Ask the bank to identify the exact restriction, the date it began, the transactions affected and the document that would remove it. A general telephone statement is not enough for a cross-border estate file.

B. How do marriage, PACS, cohabitation and British succession documents change the survivor’s position?

The survivor’s relationship with the deceased affects the ownership and succession analysis, but it does not rewrite the account agreement. A married couple may be subject to the French communauté (community-of-property regime), a séparation de biens (separation-of-property regime), a foreign matrimonial regime or a contract that requires an international-law analysis. The marriage certificate and any marriage contract should be sent to the notary with the account documents. A British marriage certificate may need a formal French translation and, depending on the document and the receiving authority, evidence of authenticity.

Under the legal community regime, Article 1401 of the Civil Code provides: “La communauté se compose activement des acquêts faits par les époux ensemble ou séparément durant le mariage”. The French word acquêts means assets acquired during the marriage that fall within the community under the relevant rules. That provision does not say that every pound in a joint account is automatically owned in equal shares. It shows why the date and nature of the deposits, the regime and any personal-property exception must be examined together.

Article 1402 of the Civil Code adds the presumption that “Tout bien, meuble ou immeuble, est réputé acquêt de communauté” when the contrary personal character has not been proved. A bank balance is movable property for this type of reasoning. The person asserting that funds were personal should assemble proof of origin. A British inheritance, a pre-marriage savings account, a pension paid before the marriage, a gift made to one spouse or sale proceeds from separate property may require a tracing exercise. Money that has moved repeatedly through a joint account becomes harder to identify, but difficulty of proof is not proof that the money belonged to one person.

Death also changes the matrimonial property relationship. Article 1441 of the Civil Code states: “La communauté se dissout : 1° par la mort de l’un des époux”. The dissolution is a calculation event. It is not the same as the distribution of the estate. The surviving spouse may first have rights arising from the liquidation of the matrimonial regime, and the deceased’s remaining assets then pass through the succession. A bank balance can therefore appear in both discussions: first as part of the matrimonial accounting, then as an asset or debt of the estate.

The statutory inheritance position of a spouse also differs from that of an unmarried partner. Where the deceased leaves children or descendants, Article 757 of the Civil Code says: “Si l’époux prédécédé laisse des enfants ou descendants, le conjoint survivant recueille, à son choix, l’usufruit de la totalité des biens existants ou la propriété du quart des biens”. Usufruit is a right to use property and take its benefits while another person holds the underlying ownership. The provision concerns the succession, not the bank’s day-to-day authority to accept a payment instruction.

A PACS (pacte civil de solidarité, the French civil solidarity pact) has its own rules and is not identical to marriage. Cohabitation without marriage or a PACS is not a general substitute for a will. A survivor may already own part of the funds, may have a contractual claim, or may be named in a will, but a long relationship and a shared French address do not by themselves answer who inherits the deceased’s share. The notary should be told about any UK will, codicil, trust arrangement, nomination, prior marriage, divorce, civil partnership and children from another relationship.

French succession tax also needs to be separated from civil ownership. Article 796-0 bis of the General Tax Code states: “Sont exonérés de droits de mutation par décès le conjoint survivant et le partenaire lié au défunt par un pacte civil de solidarité.” This exemption concerns the surviving spouse and the surviving PACS partner. It does not mean that every transfer to a partner is tax-free, that an unmarried partner automatically inherits, or that United Kingdom Inheritance Tax disappears. A British survivor should obtain an income-and-estate analysis for both countries rather than apply a French label to a UK asset.

The UK side may use different words and procedures. GOV.UK explains that the personal representative is responsible for dealing with the deceased’s estate and that probate may be needed before assets can be handled in England and Wales; in Scotland the corresponding authority is generally confirmation. The official GOV.UK estate guidance also warns that debts and taxes must be dealt with before distribution. Those documents may help explain authority over a UK account, but a grant of probate is not automatically the document that gives a survivor unrestricted access to a French joint account.

For the French file, the key document is often an acte de notoriété, a notarial deed recording evidence of heir status. Article 730-1 of the Civil Code states: “La preuve de la qualité d’héritier peut résulter d’un acte de notoriété dressé par un notaire”. The article also requires the deed to refer to the death certificate and the documents supporting the stated family position. A bank may ask for that deed, the death certificate, identity documents, civil-status evidence and the account details before releasing the deceased’s share or accepting a closure instruction.

Do not send the bank a UK probate grant with no explanation and assume it must accept it. Ask what the French bank requires, whether it needs a certified translation and whether it wants a French notarial deed or an apostilled public document. The exact formal route can depend on the document, the issuing part of the United Kingdom, the international convention relied on and the bank’s compliance policy. Preserve the original and a clear scan. A translation should identify the translator and should not silently change a name, date, address or family relationship.

II. How can the surviving British spouse or partner unblock the account or challenge the bank?

A. Which documents and urgent payments should be sent to the bank and notary?

Start with a written notification that is short, factual and traceable. State the deceased’s full name, date of death, account number, the survivor’s status as named co-holder, the address for correspondence and the action requested. Attach the death certificate, both identity documents, the marriage or PACS evidence if relevant, the most recent statement and the bank’s message referring to the freeze. Ask the bank to confirm whether the account remains a joint account, whether the survivor’s ordinary operation rights remain active and which precise transactions have been stopped.

Ask for four separate answers rather than a general promise. First, has the bank registered the death? Secondly, is the restriction an estate-document request, a compliance hold, an opposition by an heir, an account-closure process or a technical error? Thirdly, what is the balance and what pending operations existed at the date of death? Fourthly, what document or event will release the survivor’s operating access and what document will settle the deceased’s share? The request should have a deadline that is reasonable for the situation and should ask for a written reply from the bank’s estate or complaints department.

Create an evidence index for the notary. A useful bundle usually contains:

• the death certificate and, where relevant, a French translation;
• the survivor’s passport, French residence document and proof of address;
• the marriage certificate, PACS record, divorce order or evidence of cohabitation;
• all wills, codicils, UK probate or confirmation documents and prior succession deeds;
• the French account agreement, account opening form, mandate, cards and recent statements;
• statements for personal accounts that funded the joint account;
• pension award letters, payslips, rental statements, sale documents and inheritance evidence;
• a schedule of transfers, withdrawals and direct debits from six months before death until the present;
• the bank’s freeze notice, telephone notes, complaint reference and proof of delivery; and
• evidence of essential expenses that cannot be paid while the restriction continues.

Number every document and refer to the number in the covering letter. A French bank or notary should not have to guess which page proves the survivor’s identity, which page shows the balance on the date of death or which payment came from a UK pension. If an amount is in sterling, show the original amount, the date of payment and the euro amount used in the account. Keep the underlying bank statement. A conversion spreadsheet is an aid to review, not a replacement for the statement.

Urgent funeral expenses have a specific statutory route. Article L. 312-1-4 of the French Monetary and Financial Code refers to the person who has authority to arrange the funeral and the possibility of debiting the deceased’s payment accounts on presentation of the funeral invoice. The same provision also deals with certain acts needed to preserve the estate and with a simplified route for an heir who proves their status and meets the conditions for a low-value estate. The survivor should ask the bank which statutory limit and documents apply. The funeral mechanism is not a general permission to empty the joint account or to pay personal debts.

Keep funeral, rent, utilities, insurance, tax and medical payments in separate columns. If the survivor paid an expense that protected the estate, record the date, the amount, the payee and the reason. If the expense benefited only the survivor, do not describe it as an estate expense merely because it was paid from the joint account. A transparent ledger is more persuasive than a series of unexplained transfers, particularly where children or a former spouse are reviewing the account.

The survivor should normally open or use a personal account for new income and ordinary future spending, while keeping enough money available for legitimate standing orders that the bank has not cancelled. That step is not an admission that the survivor had no right to operate the joint account. It reduces the risk that a pension payment received after death will be confused with the deceased’s balance at the date of death. Tell the pension provider, employer, insurer or benefit office about the death through the correct channel and retain the confirmation. Do not redirect a payment that clearly belongs to the estate to a personal account without explaining the position.

Do not make a large withdrawal because online access suddenly returns. A joint mandate may permit an operation against the bank, while the internal ownership question remains open between the survivor and the estate. If cash is needed urgently, make the smallest reasonable payment, keep the invoice and state in writing why it was necessary. A transfer to a solicitor’s client account or to the notary may be safer than an unexplained transfer to a relative, but the recipient and purpose should still be confirmed in writing.

The UK administration should run in parallel where the deceased had British accounts, pensions or tax obligations. GOV.UK’s guidance on joint property, shares and bank accounts distinguishes joint ownership from ownership in separate shares for United Kingdom tax purposes. It warns that Inheritance Tax can depend on the deceased’s share and the value of the whole estate. That guidance should not be transplanted word for word into the French account, but it is a reminder to identify every asset and not to treat a French bank statement as the whole estate.

If the bank will not identify the alleged legal reason for the freeze, send a formal complaint to the address in the account agreement or the bank’s current complaints procedure. Ask for a copy of the relevant account terms, the date of the restriction and the name of the department handling the file. Keep the delivery evidence. A complaint is useful even if the matter later goes to the banking mediator or a court because it fixes what the bank was told and when. It should not replace an urgent application where the survivor cannot pay essential expenses or a procedural deadline is approaching.

B. What evidence, formal notices and court remedies are available if the freeze continues?

First classify the dispute. If the bank has placed a short compliance hold, the immediate remedy is a complete identity-and-source-of-funds file. If an heir has formally opposed transactions, the question is the scope and validity of that opposition. If the bank has closed or restricted the account under its contract, the notice and the contractual period must be reviewed. If a creditor’s seizure or a court order is involved, the matter is not an ordinary succession freeze and may have a separate challenge deadline. The words “frozen account” do not identify the procedure.

If the bank says that a joint account must be blocked simply because a co-holder died, refer it to the account agreement and the official French guidance, while asking for a transaction-specific explanation. The 2004 Court of Cassation decision cited above supports the proposition that the surviving holder can continue to operate a joint account unless the heirs oppose, but it does not decide the final ownership of each euro. A proportionate restriction on the deceased’s share, a request for a notarial deed or a hold caused by a separate compliance concern should not be described as the same thing as an automatic legal freeze.

When the disagreement concerns withdrawals, reconstruct the transaction rather than making a general accusation. Identify who had the card or online credentials, the date and place of the transaction, the source of the funds, the payee, the purpose and the document that supports the explanation. Save bank records before they disappear from online access. Ask the bank for the full transaction detail, not merely a yearly total. If the account was used to pay household bills, label those payments separately from gifts, cash withdrawals, transfers to a personal account and payments made after death.

The burden of proof matters. Article 1353 of the Civil Code states: “Celui qui réclame l’exécution d’une obligation doit la prouver.” The person claiming performance must prove the obligation, while the person claiming release must prove payment or the event that extinguished it. In Cour de cassation, first civil chamber, 4 February 2026, no. 23-20.448, the Court held that relatives claiming that €8,774.35 of cash withdrawals from a joint account had been used for personal needs had to establish that proposition; the appeal court had “inversé la charge de la preuve”. The decision does not give a survivor permission to keep unexplained money. It does prevent a court from ordering a report to the estate merely because the survivor cannot prove a negative before the claimant proves the withdrawal and its personal use.

There is a serious difference between an unexplained transaction and intentional concealment. Article 778 of the Civil Code provides: “Sans préjudice de dommages et intérêts, l’héritier qui a recelé des biens ou des droits d’une succession”. Recel successoral is the French civil-law concept of concealing or diverting succession assets to undermine equality between heirs. In Cour de cassation, first civil chamber, 5 March 2014, no. 13-14.197, the Court upheld reasoning that the concept covers fraud intended to break equality in the distribution and that undisclosed gifts and withdrawals can matter when the evidence establishes the intention. A survivor should therefore disclose relevant transfers, even where the survivor believes the money was lawfully available under the joint mandate.

Another useful decision is Cour de cassation, first civil chamber, 30 September 2009, no. 07-21.156. The published decision records an estate analysis in which the surviving joint holder retained the practical ability to use the account in the absence of opposition, while the balance at death and later withdrawals had to be accounted for. The point is narrow but important: operating authority and final ownership are separate questions. A survivor can ask the bank to restore normal operation without asking the bank to declare that every later withdrawal belongs exclusively to the survivor.

If the parties cannot agree on the deceased’s share, the dispute may become an indivision dispute, meaning ownership in undivided shares. Article 815 of the Civil Code states: “Nul ne peut être contraint à demeurer dans l’indivision et le partage peut toujours être provoqué”. An heir can seek a division or a judicial settlement. That does not automatically produce an immediate transfer from the bank, but it gives the parties a route when a family settlement has failed. The bank should not be asked to decide the entire inheritance dispute merely because it holds the account.

Urgency can justify a focused court application. Article 815-6 of the Civil Code states: “Le président du tribunal judiciaire peut prescrire ou autoriser toutes les mesures urgentes que requiert l’intérêt commun.” The tribunal judiciaire is the ordinary French civil court. Depending on the evidence and the procedural route, an urgent application may seek a measure protecting the account, payment of a necessary expense, appointment of an administrator or another step required to preserve the common interest. The precise application, court and documents depend on the account, the parties and the urgency; a generic internet form is not a substitute for checking jurisdiction.

A formal notice to the bank should remain measured. Identify the account, the date of death, the fact that the survivor is a named co-holder, the restriction complained of, the rule or account term relied on, the documents attached and the action requested. Ask for restoration of the operation that the joint mandate permits, or for a written and legally intelligible explanation of why it cannot be restored. Reserve the survivor’s rights concerning the ownership of the balance. Do not threaten criminal proceedings merely because the bank asks for an acte de notoriété, and do not accept a release of claims merely because the bank offers a small interim payment.

If the bank’s conduct has caused a proven loss, a claim may need to be brought against the bank, the person who made unauthorised withdrawals, or both. The legal theory will depend on the contract, the instructions received by the bank, the notice of death, the payment instrument, the causal link and the loss. A court will want evidence of the date on which the bank knew of the death, what it was asked to do, what it actually did and what alternative protection was available. A bank’s failure to freeze a joint account is not automatically a breach, just as a survivor’s ability to operate it is not automatically proof of ownership.

Cross-border evidence should be assembled before a hearing is fixed. A British birth, marriage or death record, a probate grant, a Scottish confirmation, a will, a pension statement and a bank statement may all use different names, addresses or dates. Prepare a chronology with the original document title, issuing authority, date, language, translation status and the proposition it proves. If the deceased lived in France but maintained a UK domicile argument, record the evidence rather than choosing a conclusion from the nationality alone. The French notary and the UK personal representative should exchange information so that the same account is not declared with two inconsistent balances.

Do not ignore a deadline while waiting for the family to agree. A bank complaint, a notarial request, an urgent court application, a succession declaration and a challenge to a creditor’s seizure can all run on different clocks. Ask the bank, notary and any enforcement officer to state the date from which they calculate their response or challenge period. Send urgent documents by a traceable channel and keep proof of receipt. If the survivor is outside France, appoint a French address or representative for formal correspondence where appropriate, but keep direct access to the original digital and paper records.

The safest outcome is often a staged settlement. The bank confirms the account history and restores ordinary operation to the extent required by the joint mandate. The notary calculates the matrimonial and succession positions. The survivor pays documented estate expenses and keeps a reserve for disputed amounts. The heirs receive a schedule of the balance, credits and withdrawals, with an agreed date for the final distribution. If a sum remains disputed, place it in a clearly identified account or with the notary rather than mixing it with the survivor’s pension and household money. That approach protects the survivor without concealing the estate.

Conclusion

A British survivor should not accept an unexplained total freeze of a French joint account as the automatic result of death. The account will normally continue to operate for the surviving named holder, subject to the convention de compte, an opposition by heirs, a compliance restriction, a seizure or another specific legal event. The deceased’s share still has to be identified at the date of death and settled through the matrimonial and succession analysis. The survivor’s own contributions, the deceased’s deposits, the marriage or PACS position, the will, the children and the UK estate documents all affect the result.

Send a written notice, preserve the balance and transaction history, separate personal money from estate money, obtain the acte de notoriété or other authority requested by the notary, and ask the bank to state the precise reason for every restriction. Keep invoices for funeral and essential expenses. If a family member alleges misuse, require the allegation to be tied to identified transactions and answer it with a dated evidence schedule. If the bank will not restore lawful operation or explain the restriction, obtain advice promptly about a formal complaint, a negotiated release or an urgent application before the competent French court.
