You married in England, signed nothing, and thought that was the end of the paperwork. Under English law that instinct is broadly right: each of you owns what is in your name, and marriage by itself does not merge your property. Then you moved to France, bought a house in the Dordogne or a flat in the Paris suburbs, opened a joint account, and started paying the mortgage from one salary while the other covered the bills. If the marriage ends, whether by divorce or by death, a French notaire, the public officer who winds up estates and divides matrimonial property, will ask a question you never had to answer in England: under which régime matrimonial, which matrimonial property regime, do you actually live. The answer decides who owns the house, who keeps the savings, who bears the debts, and what the surviving spouse inherits. For British couples in France after Brexit, the answer is never automatic, and the English reflex of keeping everything in separate names can produce the opposite of the intended result once French community rules apply. This guide explains the whole mechanism in order. First, how French courts decide which law governs a British couple, and what the French default regime puts in the common pot and what it leaves personal. Second, how the property is divided on divorce or death, how you change regime when your English starting point no longer suits your French life, and how you challenge a refusal, a voidable act or a mistaken division.
I. We Married in England and Moved to France: Which Matrimonial Regime Governs Our Money and Our House?
A. Married Without a Contract in England, Resident in France: How Is the Applicable Law Decided?
Start with the English position, because it explains why so many British couples arrive in France with no paperwork at all. England and Wales know no default community of property between spouses. Apart from the family home protections on divorce and the claims a court can make under matrimonial legislation, ownership during the marriage follows the ordinary law of property: what you earn is yours, what you buy in your name is yours, and a joint account is shared. There is no contrat de mariage, no marriage contract, to sign, and most couples never see a solicitor about ownership until a relationship breaks down. France works the other way round. French law treats every married couple as living under a property regime from the day of the wedding, whether they signed anything or not. The Civil Code states the principle of contractual liberty first: “La loi ne régit l’association conjugale, quant aux biens, qu’à défaut de conventions spéciales que les époux peuvent faire comme ils le jugent à propos, pourvu qu’elles ne soient pas contraires aux bonnes moeurs ni aux dispositions qui suivent.” (Article 1387 of the Civil Code on Légifrance). In plain terms, the statute governs the spouses’ property relations only where they have made no special agreement, and any agreement they make must respect public policy and the mandatory provisions that follow. Where there is no agreement, the default regime applies, and that default is a community: “La communauté, qui s’établit à défaut de contrat ou par la simple déclaration qu’on se marie sous le régime de la communauté, est soumise aux règles expliquées dans les trois sections qui suivent.” (Article 1400 of the Civil Code on Légifrance). So a British couple who married in a register office in Manchester with no contract, then settled in France, can find themselves governed by French community rules without ever signing a French document, provided French conflicts rules point to French law.
Which law the French judge applies is decided by an international convention that still governs most British marriages in France. France is a party to the Hague Convention of 14 March 1978 on the law applicable to matrimonial property regimes, whose full text is published by the Hague Conference (Hague Convention of 14 March 1978, HCCH). The United Kingdom never joined that Convention, and Brexit changed nothing about that, but a French court applies the Convention as its own conflicts rule even when the designated law is English law. Where the spouses made no designation of the applicable law before marriage, Article 4 of the Convention works through a cascade. If the spouses established their first habitual residence, their première résidence habituelle, in the same State shortly after the wedding, that State’s internal law governs. Failing that, if they share a common nationality, the law of that nationality governs. Failing both, the regime is governed by the internal law of the State with which, taking all the circumstances into account, it presents the closest connection, the liens les plus étroits. Take the common British case: two British nationals marry in London and set up their first home together in London. First shared habitual residence and common nationality both point to England, so English separation of property governs, and the later move to Lyon or Bordeaux does not by itself rewrite the regime. Take the harder case the courts actually fight over: spouses of different nationalities who never lived together in one State immediately after the wedding, who worked in several countries, and who installed themselves somewhere years later. The Cour de cassation, the supreme court for civil matters, has just restated how strict the cascade is. In a judgment of 1 October 2025 on appeal number 23-17.313, a wife criticised the appeal court for holding Saudi law applicable on the ground that the couple had established their first habitual residence in Saudi Arabia when they moved there in 1996, although they had married in 1994 without sharing a nationality: “en application de l’article 4 de la Convention de La Haye du 14 mars 1978, à défaut de résidence habituelle des époux sur le territoire du même État juste après le mariage, et à défaut de nationalité commune, leur régime matrimonial doit être soumis à la loi interne de l’État avec lequel, compte tenu de toutes les circonstances, il présente les liens les plus étroits” (Cass. 1re civ., 1 Oct. 2025, no. 23-17.313 on courdecassation.fr). The Court upheld the complaint and held that the criterion of the spouses’ first habitual residence after the marriage, provided for by Article 4 of the Convention, does not apply where the spouses had their first habitual residence after the marriage in different States, so the appeal court should have determined the law of closest connection instead of treating a later installation as the first residence. For British readers the lesson is direct: a residence taken up years after the wedding is not the première résidence habituelle, and a couple with mixed nationality and a wandering early married life may be governed neither by English nor by French law until a court works through every circumstance.
Two refinements complete the picture. First, the Convention also allows spouses to designate the applicable law themselves, within its conditions, which is why a well-drafted English or French marriage contract can settle the question in advance, provided the designation satisfies the Convention’s requirements on form and timing. Second, for weddings celebrated on or after 29 January 2019, the European Union’s Matrimonial Property Regulation, Regulation 2016/1103, applies in France and in the other participating States, with its own cascade based on the first common habitual residence and its own provisions for choosing the applicable law (Regulation (EU) 2016/1103, published in the Official Journal of the European Union). The United Kingdom never took part in that Regulation, and Denmark and Ireland stand aside as well, but a British couple living in France can still fall under it where the French connecting factors point to a participating State, most often France itself. In practice, therefore, three generations of couples coexist in the British community in France: those married before the Convention mattered, those governed by the 1978 Convention, and those married since 2019 who may fall under the EU Regulation. The practical guidance of the French administration on marriage contracts and on changing regime gives a useful first orientation, but it does not resolve conflicts of law (service-public.fr, marriage contract; service-public.fr, changing matrimonial regime). British government guidance for nationals living in France usefully recalls that local law governs property, money and succession once you are resident here (gov.uk, Living in France). The only safe approach is to have the applicable law identified in writing, ideally in a contract or a designation the French notaire will accept, before you buy, borrow or sign anything important.
B. Under the French Default of Community of Acquests: What Is Jointly Owned, What Stays Personal, and Who Owes What to Whom?
Where French law governs and the couple signed nothing, they live under the communauté réduite aux acquêts, the community of acquests, which pools what the marriage earns and leaves the rest personal. The definition is short and worth reading literally: “La communauté se compose activement des acquêts faits par les époux ensemble ou séparément durant le mariage, et provenant tant de leur industrie personnelle que des économies faites sur les fruits et revenus de leurs biens propres.” (Article 1401 of the Civil Code on Légifrance). Every acquisition made by either spouse during the marriage, whether together or separately, belongs to the community where it comes from their work or from savings made on the fruits and income of their personal property. Salaries, professional earnings, the house bought with those earnings, the savings accumulated year by year: all common, even if only one spouse worked and even if the title deeds name only one buyer. What stays personal, or propre, is essentially what predates the marriage or falls outside its earnings: property owned before the wedding, gifts and inheritances received during the marriage, and property that replaces them through a documented reinvestment, the emploi ou remploi. The boundary is policed by a presumption that surprises English buyers: “Tout bien, meuble ou immeuble, est réputé acquêt de communauté si l’on ne prouve qu’il est propre à l’un des époux par application d’une disposition de la loi.” (Article 1402 of the Civil Code on Légifrance). Every movable or immovable asset is presumed to be a community acquisition unless proved personal under a provision of the statute, and where the asset carries no mark of its origin, the spouse claiming personal ownership must prove it in writing, through an inventory or pre-constituted evidence, failing which the judge may consider family papers, bank records and invoices, and even testimony where written proof was materially or morally impossible to obtain. A British spouse who sells a London flat owned before the marriage and pours the proceeds into the French family home without a written declaration of reinvestment in the purchase deed therefore risks seeing the whole house treated as community property, however clear the money trail feels in personal memory.
The community also collects the income of personal property and pays the corresponding burdens, which is where the accounting between the three estates, his, hers and theirs, becomes technical. The Cour de cassation stated the principle in a judgment of 13 October 2021 on appeal number 19-24.008, ruling on a farming couple’s divorce accounts: “Vu les articles 1401, 1403 et 1437 du code civil :” then “Il ressort de ces textes que la communauté, à laquelle sont affectés les fruits et revenus des biens propres, doit supporter les dettes qui sont la charge de la jouissance de ces biens et que leur paiement ne donne pas droit à récompense au profit de la communauté lorsqu’il a été fait avec des fonds communs.” (Cass. 1re civ., 13 Oct. 2021, no. 19-24.008 on courdecassation.fr). Because the community takes the fruits and income of personal assets, it must bear the debts attached to their enjoyment, and paying those debts from common funds gives the community no claim for repayment. The mirror mechanism is the récompense, the compensation owed where one estate has enriched itself at the expense of another. The statute provides: “La communauté doit récompense à l’époux propriétaire toutes les fois qu’elle a tiré profit de biens propres. Il en est ainsi, notamment, quand elle a encaissé des deniers propres ou provenant de la vente d’un propre, sans qu’il en ait été fait emploi ou remploi.” (Article 1433 of the Civil Code on Légifrance). The community owes compensation to the owner spouse whenever it has profited from personal property, in particular where it has taken in personal funds or the sale price of a personal asset without reinvestment, and disputed profit may be proved by any means, including testimony and presumptions. The Cour de cassation applied exactly this rule on 15 January 2025 in appeal number 23-10.887, where a husband claimed compensation after his personal account became a joint account: “Vu l’article 1433 du code civil :” then “Selon ce texte, il incombe à celui qui demande récompense à la communauté d’établir que les deniers provenant de son patrimoine propre ont profité à celle-ci.” (Cass. 1re civ., 15 Jan. 2025, no. 23-10.887 on courdecassation.fr). Whoever claims compensation must prove that funds from his or her personal estate benefited the community, and turning a personal account into a joint account can count as the community taking in personal funds. For British couples this is the daily danger zone: the UK savings account converted into a joint account for convenience, the inheritance from a parent in Kent used to repay the French mortgage, the rental income of a pre-marriage London flat spent on the French household. Each movement creates or extinguishes a récompense, and the spouse who cannot prove the movement with bank records usually loses the argument years later before the notaire or the family judge, the juge aux affaires familiales.
Between the end of the community and the final division stretches a period English lawyers often overlook: the post-community indivision, the undivided ownership in which the former spouses hold the ex-community assets while the accounts are drawn up. Money spent or received during that interval is governed by the law of undivided ownership rather than by récompenses, notably the rule that an undivided co-owner who has improved or preserved the property from personal funds is credited accordingly. The Civil Code provides for that accounting in the law of partition: “Lorsqu’un indivisaire a amélioré à ses frais l’état d’un bien indivis, il doit lui en être tenu compte selon l’équité, eu égard à ce dont la valeur du bien se trouve augmentée au temps du partage ou de l’aliénation. Il doit lui être pareillement tenu compte des dépenses nécessaires qu’il a faites de ses deniers personnels pour la conservation desdits biens, encore qu’elles ne les aient point améliorés.” (Article 815-13 of the Civil Code on Légifrance). A British spouse who keeps paying the French mortgage alone after separation, or who funds essential roof repairs from a personal account while the divorce drags on, therefore acquires a quantified claim against the undivided estate, measured by the increase in value or by the necessary outlay, rather than a vague moral credit. Keep every statement, every invoice and every transfer slip from the day the community ends, because the final settlement rewards the spouse with the paperwork and punishes the spouse with only a story.
II. Divorce, Death or a Change of Plan: How Do You Protect Your Spouse and Put a Wrong Outcome Right?
A. If We Divorce or One of Us Dies in France: How Are the House, the Accounts and the Debts Divided?
On divorce in France, the family judge pronounces the divorce and the notaire liquidates, or winds up, the regime: the community is valued, the récompenses are calculated each way, the personal assets are taken back, and what remains is split in half, subject to any court-ordered compensatory allowance, the prestation compensatoire, which corrects disparity in living standards. The family home itself enjoys a special protection during the marriage that many British spouses discover too late. The statute provides: “Les époux ne peuvent l’un sans l’autre disposer des droits par lesquels est assuré le logement de la famille, ni des meubles meublants dont il est garni. Celui des deux qui n’a pas donné son consentement à l’acte peut en demander l’annulation : l’action en nullité lui est ouverte dans l’année à partir du jour où il a eu connaissance de l’acte, sans pouvoir jamais être intentée plus d’un an après que le régime matrimonial s’est dissous.” (Article 215 of the Civil Code on Légifrance). Neither spouse may alone dispose of the rights securing the family dwelling or of its household furniture, and the spouse who did not consent may seek annulment within a year of learning of the act, and never more than a year after the regime dissolved. The Cour de cassation gives this text its full force: “Vu l’article 215, alinéa 3, du code civil ;” then “Attendu que, selon ce texte, les époux ne peuvent l’un sans l’autre disposer des droits par lesquels est assuré le logement de la famille” (Cass. 1re civ., 22 May 2019, no. 18-16.666 on courdecassation.fr), in a case where a husband had given away the bare ownership of his personal properties, including the family home, to children of an earlier marriage while reserving the usufruct to himself alone, and the Court allowed the wife’s annulment claim to proceed. A British husband in France cannot therefore give away, sell or mortgage the French family home over his wife’s head even where the deeds are in his sole name, and a British wife has the symmetrical protection. Note the related trap for couples who hold the home through a property company, the société civile immobilière: in a judgment of 14 March 2018 on appeal number 17-16.482, the Court examined whether Article 215 could defeat a sale of a flat held through such a company and looked to the company’s articles and to who actually enjoyed the premises, so holding the family roof inside a company does not reliably escape the protection (Cass. 1re civ., 14 Mar. 2018, no. 17-16.482 on courdecassation.fr). Before signing any disposal of the French home, both spouses should therefore verify in writing that the other consents, and the spouse who learns of a unilateral sale should see a lawyer immediately, because the one-year clock runs from knowledge.
On death, the regime is liquidated first and the succession, the estate, is divided afterwards, which means the matrimonial answer comes before the inheritance answer. The surviving spouse’s statutory rights then depend on the children. The statute provides: “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 lorsque tous les enfants sont issus des deux époux et la propriété du quart en présence d’un ou plusieurs enfants qui ne sont pas issus des deux époux.” (Article 757 of the Civil Code on Légifrance). Where the deceased leaves children, the survivor takes either the usufruct, the usufruit, of the whole existing estate or full ownership, the pleine propriété, of one quarter where all the children are the couple’s joint children, and takes full ownership of one quarter, with no choice, where at least one child comes from another relationship. The distinction matters enormously for blended British families, which are common in the expatriate community. The Cour de cassation drove the point home on 5 March 2025 in appeal number 23-11.430, where daughters argued that their stepmother, faced with a child born of the deceased’s earlier union, had never validly chosen and was therefore deemed to hold a usufruct that died with her: “Vu l’article 757 du code civil :” then “Selon ce texte, si l’époux prédécédé laisse un ou plusieurs enfants qui ne sont pas issus des deux époux, le conjoint survivant recueille la propriété du quart des biens existants.” (Cass. 1re civ., 5 Mar. 2025, no. 23-11.430 on courdecassation.fr). Where a non-joint child exists, the survivor’s legal rights can only be ownership of one quarter, with no option for usufruct of the whole, whatever ambiguous paperwork the parties signed. Add the spouse’s gifts and the deceased’s will on top: a donation between spouses or an English will choosing English law for the succession under the EU Succession Regulation can widen the survivor’s share, but it cannot erase the children’s reserved portion, the réserve héréditaire, and matrimonial advantages favouring one spouse are cut back where non-joint children exist. The statute on matrimonial advantages states: “Les avantages que l’un ou l’autre des époux peut retirer des clauses d’une communauté conventionnelle, ainsi que ceux qui peuvent résulter de la confusion du mobilier ou des dettes, ne sont point regardés comme des donations. Néanmoins, au cas où il y aurait des enfants qui ne seraient pas issus des deux époux, toute convention qui aurait pour conséquence de donner à l’un des époux au-delà de la portion réglée par l’article 1094-1 , au titre ” Des donations entre vifs et des testaments “, sera sans effet pour tout l’excédent” (Article 1527 of the Civil Code on Légifrance). Advantages drawn from a conventional community are not treated as gifts, yet where non-joint children exist, any arrangement giving a spouse more than the disposable portion is ineffective for the excess. A British couple with children from earlier marriages should therefore coordinate three documents, the matrimonial regime, the will and any designation of applicable law, rather than assuming an English will alone protects the survivor in the French house.
Practical consequences follow for the paperwork British families actually hold. An English will remains useful in France: it can designate English law for the succession, name executors, and dispose of English assets, but it must be translated, and the French notaire will still require proof of its validity and of the English grant of probate, normally with an apostille, before releasing French assets or transferring the French land register entry. Where the couple owns French land, the transfer ultimately passes through the French land publicity system, and the notaire‘s acte de notoriété, the deed establishing who the heirs are, governs the French side. Joint ownership devices imported from England, such as buying en indivision, in undivided shares, with a survivorship agreement, the tontine clause, or through a property company, each interact differently with the regime and with the children’s reserve, and none of them replaces advice on the regime itself. Where the surviving spouse or the children disagree with the notaire‘s liquidation, the remedy is an action for judicial partition before the tribunal judiciaire, the civil court, with a full accounting of récompenses, valuations at the date of partition, and, where needed, a court-appointed notaire to draw up the accounts. Start that challenge with complete bank records from both countries, because the French judge divides proved figures, not recollections of who paid what in which currency.
B. If Our English Starting Point No Longer Suits Us: How Do We Change Regime in France and Challenge Refusals or Errors?
Many British couples conclude after a few years in France that their starting regime no longer fits: the community exposes a new French business to the other’s creditors, or separation of property leaves the non-earning spouse dangerously unprotected in the French house, or a second marriage calls for a tailored community with a full transfer to the survivor. French law allows a change, and since the reforms the procedure is largely handled before the notaire rather than the court. The statute provides: “Les époux peuvent convenir, dans l’intérêt de la famille, de modifier leur régime matrimonial, ou même d’en changer entièrement, par un acte notarié. A peine de nullité, l’acte notarié contient la liquidation du régime matrimonial modifié si elle est nécessaire.” (Article 1397 of the Civil Code on Légifrance). Spouses may agree, in the family’s interest, to modify their regime or change it entirely by notarial deed, and on pain of nullity the deed must contain the liquidation of the former regime where liquidation is needed. The rest of the article organises information and opposition: persons who were parties to the modified contract and each spouse’s adult children are personally informed and may object within three months; creditors are informed through a notice published on an authorised legal announcements medium in the spouses’ home district and may object within three months of publication; and where there is an objection, the deed goes to the family court of the spouses’ domicile for approval, the homologation. The administration’s guidance describes the same sequence of notarial deed, information, publication and, only if opposed, court approval (service-public.fr, changing matrimonial regime). Common switches include moving from community to séparation de biens, separation of property, where one spouse carries business risk; moving from separation to community to protect the homemaker; adopting a communauté universelle, universal community, with a clause attributing the whole estate to the survivor, which strongly protects the spouse but must be measured against the children’s reserve and the Article 1527 reduction where non-joint children exist; or inserting a clause de préciput, a clause allowing the survivor to take a defined asset before partition. For British couples the change of regime is also the natural moment to add, alongside it, a designation of the applicable law and a coordinated pair of wills, so that the regime, the succession law and the tax position point in the same direction instead of contradicting each other.
Each stage of that sequence can be challenged, and the challenge routes are the teeth of the procedure. Adult children or former contracting parties who were never personally informed can attack the regularity of the information; creditors who discover a change that strips their debtor can oppose within their three-month window and then argue before the court that the change defrauds them; spouses facing an opposition can ask the court to approve the deed despite it by showing the family’s interest, with valuations and creditor safeguards to support them. Errors in the liquidation itself, a forgotten récompense, a misvalued house, a personal asset wrongly swept into the community, are contested through a demand for a corrected account before the notaire and, failing agreement, through judicial partition with expert valuation. Unilateral disposals of the family home in breach of Article 215 are met with the annulment action described above, within a year of knowledge and never beyond a year after dissolution of the regime. And where the dispute is really about which law governs, because the notaire applies French community rules while the family insists English separation always applied, the point must be raised as a preliminary question of applicable law with evidence of the first habitual residence, nationalities, and the spouses’ designations, relying on the Hague cascade and the October 2025 judgment discussed above. Raise conflicts of law early: a liquidation negotiated for months on the wrong legal basis is difficult to reopen once the partition deed is signed and published at the land registry.
For couples in Paris and the Île-de-France, the procedure has local features worth building into your timetable. The competent court for a contested change is the tribunal judiciaire of the spouses’ domicile, principally Paris, Nanterre, Bobigny or Créteil according to your department, and approval applications join a busy family docket, so allow several months between the opposed deed and the approval hearing. Publication of the creditor notice runs in an authorised announcements medium of your home department, and Paris practices on land publicity are exacting: the change and any liquidation affecting Parisian or suburban property must be drawn, registered and published without descriptive error, or the land registry, the service de publicité foncière, will reject the filing and the whole timetable slips. Prepare the file a Paris notaire expects: marriage certificate with apostille and sworn translation, English marriage contract or solicitor’s letter confirming there was none, French property deeds, loan statements, bank records in both countries, company accounts where a business motivates the switch, and the children’s birth certificates for the information formalities. Bilingual couples should also align the French deed with any English lifetime arrangements, because a French universal community and an English discretionary trust over the same assets will pull in opposite directions on the first death. Handled with that file in order, a change of regime in the Paris region typically completes within a few months where nobody opposes, and a contested approval remains a contained family-court case rather than open-ended litigation.
Conclusion
A British marriage does not travel to France unchanged. Identify first which law governs your regime, using the Hague cascade of first shared residence, common nationality and closest connection, and distrust any assumption that the move itself switched you from one system to the other. Then read your French default literally: earnings and savings during the marriage are common, personal assets need written proof, income of personal property feeds the community while its burdens fall on it, and every transfer between the three estates creates a measurable récompense or, after separation, an undivided-ownership account. Protect the family home through joint consent, coordinate the regime with wills and designations of applicable law, and use the notarial change procedure where your English starting point no longer fits your French household, keeping a sharp eye on opposition periods and on the rights of non-joint children. With the applicable law settled in writing and the money movements proved on paper, divorce or death in France becomes an accounting exercise the notaire can close; without them, it becomes an argument about memories that the spouse with the records wins.
