A British citizen living in France may be able to start divorce proceedings before a French court even when the other spouse has returned to the United Kingdom. Brexit did not make every French application impossible, but it removed the comfort of treating a France–UK case as an ordinary intra-EU file. The first question is now jurisdiction: which country has a sufficiently real connection with the marriage, and which court can be seised without creating an avoidable dispute? The second is proof. A French address, a holiday home or a residence card is not, by itself, a complete answer to the question of habitual residence. The third is scope. A French divorce, arrangements for children, maintenance and the division of pensions may be governed by different instruments and may not be recognised or enforced in the same way on both sides of the Channel. That distinction matters when the other spouse has stopped paying, moved again or begun proceedings in the UK.

This guide addresses a new case issued after Brexit, principally involving England and Wales. It explains how to test French jurisdiction, what to do before either spouse files, how a spouse in the UK is served, and why financial orders must be planned from the beginning. It is separate from the later problem of having a UK divorce recognised in France, which requires its own recognition and civil-status strategy.

I. Can you start divorce proceedings in France when your spouse lives in the UK?

A. Which French court can hear the divorce after Brexit?

The short answer is yes, potentially. The spouse’s current UK address does not automatically deprive the French courts of jurisdiction. The court must identify a connecting factor recognised by the applicable European, French and, where relevant, UK rules. That analysis should be completed before an assignation, meaning the formal document by which the claimant summons the other spouse before the court, is issued.

For a new case, the relevant EU framework is principally Council Regulation (EU) 2019/1111, commonly called Brussels II ter. Its Article 3 gives jurisdiction to the courts of the Member State where, among other alternatives, the spouses are habitually resident, where they last lived habitually and one still lives there, where the respondent is habitually resident, where either spouse is habitually resident in a joint application, or where the applicant has lived habitually for at least one year immediately before applying. A six-month route can exist for a national of the relevant Member State. That last nationality route should not be confused with the one-year residence route: two British nationals cannot rely simply on their British nationality as though the United Kingdom were still an EU Member State.

Brussels II ter is an EU regulation. It structures jurisdiction for a French court as the court of a Member State; it is not a general post-Brexit treaty that gives a British court automatic priority or guarantees mutual recognition of every new French order. The official GOV.UK guidance on family disputes involving the EU distinguishes transitional proceedings from new cases and explains that, for new cases in England and Wales, Brussels IIa was revoked and domestic jurisdiction rules apply. A French lawyer and an England and Wales family lawyer should therefore compare the two possible proceedings, rather than assuming that the first online form submitted will settle the matter.

There is an important distinction between jurisdiction and applicable law. Jurisdiction answers “which court may decide?” Applicable law answers “which legal rules will that court apply?” Article 309 of the French Civil Code is a conflict-of-laws provision. Légifrance states that Le divorce et la séparation de corps sont régis par la loi française, meaning that divorce and legal separation are governed by French law, in particular where both spouses are French, both have their domicile in France, or no foreign law accepts jurisdiction while the French courts are competent. The complete Article 309 Code civil should be read with the applicable European conflict-of-laws instruments and the facts of the marriage. A French court having jurisdiction does not automatically mean that every issue will be decided under French law.

At local level, the French juge aux affaires familiales (JAF), or family affairs judge, is allocated territorially under Article 1070 of the Code of Civil Procedure. The ordinary starting points are the place where the family resides, the residence of the parent with whom minor children habitually live when the parents are separated, or the residence of the spouse who did not initiate the proceedings. In a joint application, the parties can choose the place where either spouse resides. The text adds a sentence that is easy to overlook: La compétence territoriale est déterminée par la résidence au jour de la demande. That is why a last-minute move, an unoccupied property or a temporary stay should not be treated as a substitute for a real residence analysis. See the current Article 1070 CPC.

The central factual idea is habitual residence. It is not identical to nationality, tax residence, the address printed on a card, or the place where a couple owns a house. The court may examine where the person actually organised ordinary life: the home used most of the year, utilities, local registration, work or retirement arrangements, schooling, doctors, social relationships, tax correspondence, banking, transport and the chronology of moves. A person may retain UK links while having transferred the centre of family life to France; another may have a French property but remain habitually resident in the UK.

The Cour de cassation’s First Civil Chamber applied this fact-sensitive method in 30 November 2022, no. 21-15.988. The case concerned a couple with links to France and Belgium, and the Court upheld French jurisdiction after the lower courts considered the stability of the couple’s social life, spending, property work and relationships in France. It is not a post-Brexit France–UK decision, but it is a useful warning: habitual residence is proved through the pattern of life, not through a single document. The relevant question is where the person has actually established a stable centre of interests at the moment the court is seised.

Build a dated residence table before filing. For each month or quarter, record where each spouse slept most often, where children attended school, where work was performed, where the family paid household bills, where healthcare was used, and where official correspondence was received. Mark temporary visits separately. If the couple moved in stages, preserve evidence for each stage. A French tax number may support the chronology, but it does not decide divorce jurisdiction. A Withdrawal Agreement residence card may support lawful residence, but it also does not replace factual proof. The court will compare the whole picture.

Do not confuse a French court’s jurisdiction with the ability to serve or enforce its decision in the UK. Those are separate procedural questions. Nor should a British spouse assume that a French address makes a French divorce automatically preferable. The right forum depends on the children’s habitual residence, the location of assets and pensions, the likely applicable law, the financial remedies available in each jurisdiction and the risk that a second court will later be asked to recognise or implement the result.

B. What happens if France and the UK are both possible forums?

Cross-border divorce should be treated as a forum-coordination problem from day one. “Forum” means the country and court system in which a case is brought. France and England and Wales may each have a plausible connection. Scotland and Northern Ireland have different rules again; the GOV.UK guidance cited above expressly applies to England and Wales only.

For proceedings commenced before the end of the transition period, the Withdrawal Agreement preserved specific European rules. For new proceedings, those transitional protections cannot simply be reused. The UK guidance explains that the English and Welsh court may apply domestic rules and has discretion to stay proceedings when a case is continuing elsewhere. That is materially different from relying on an automatic intra-EU lis pendens mechanism. Lis pendens is the rule intended to manage parallel proceedings concerning the same subject matter. A British reader should not assume that a French filing will automatically make an English case impossible, or that an English filing will automatically make a French case disappear.

Before issuing, prepare a two-column forum note:

• French connection: each spouse’s habitual residence, last common home, children’s location, marriage record, French assets, French income and the practical ability of the JAF to determine provisional measures.
• UK connection: the spouse’s domicile or habitual residence, the appropriate jurisdiction within the UK, the location of employment and pensions, the English or Welsh financial-remedy route and the likely recognition route for a French judgment.

The note should identify whether either spouse has already instructed a lawyer, sent a formal petition, received a draft application or signed a financial agreement. Preserve dates and copies. A message saying “I have filed” is not the same as a court being validly seised. Conversely, a French assignation may create procedural consequences even before the UK spouse understands the French document. An early cross-border review is usually cheaper than repairing an avoidable jurisdiction objection after service.

Children create a separate layer. Divorce jurisdiction and parental-responsibility jurisdiction are related but not identical. The child’s habitual residence, the place of wrongful removal or retention, and the 1996 Hague Convention may control long-term decisions. The official GOV.UK guidance explains that new England and Wales children cases use the 1996 Hague Convention framework, while international abduction cases involve the 1980 Hague Convention. If a child normally lives in France, that may support a French forum for child arrangements; it does not give the divorce court unlimited power over every issue involving a child who lives in the UK.

Maintenance is another separate layer. Child maintenance, spousal maintenance, temporary support during the case and a French prestation compensatoire do not perform the same legal function. The GOV.UK guidance records that new England and Wales maintenance cases use non-EU rules and that the United Kingdom uses the 2007 Hague Convention with participating EU States for recognition and enforcement of maintenance decisions. A French court may be able to address an issue connected with the divorce, but the route to enforce a recurring payment in the UK must be mapped separately.

For the same reason, do not use the word “financial order” as though it had one universal meaning. In England and Wales it may refer to a consent order, pension-sharing order, lump sum or maintenance order. In France, the court may determine liquidation of the matrimonial property regime, provisional support, allocation of the family home and a compensatory payment. The court, applicable law, tax treatment and enforcement machinery can differ for each asset and obligation.

A sensible first 48-hour response to a threatened filing is practical:

1. Save the marriage certificate, any existing court papers, the last three years of addresses and all messages showing where the family lived.
2. Identify the children’s current and habitual residence, passports, school and health arrangements, and any travel or removal concern.
3. List French and UK bank accounts, homes, companies, pensions, trusts, inheritances and debts without transferring or hiding assets.
4. Ask both advisers to compare jurisdiction, applicable law, service, interim relief, financial disclosure and recognition before a final forum decision.

A spouse in France may need urgent interim protection for housing, household expenses or a child, but urgency does not justify an unverified jurisdiction allegation. A spouse in the UK should not ignore French papers simply because they are in French. The answer is to obtain a translation, record the date of service and take advice before the deadline shown in the document expires.

II. What evidence and financial protection are needed in a France–UK divorce?

A. How should the French application and service on the UK spouse be prepared?

A contested French judicial divorce normally requires each spouse to have a lawyer. The official Service-Public procedure guide, verified on 1 March 2026, explains that the lawyer seises the JAF by an assignation en divorce, or that the spouses may use a joint application when they agree to start together. The application can ask for provisional measures concerning the home, household expenses, debts, children and support while the case continues.

That procedure has practical consequences for a spouse living in the UK. The French court must be validly seised, the document must be served by a legally permitted method, and the respondent must have a genuine opportunity to participate. Service is not proved merely by an email, a WhatsApp message or an informal translation. The method may involve the applicable international service framework, a competent authority, a French commissaire de justice (the modern French term for a judicial officer formerly called a bailiff), or another route permitted by the law of the place of service. The correct route depends on the date, document and country within the UK.

The United Kingdom’s official family-law guidance also shows why cross-border service and participation must be planned rather than improvised. A French spouse should ask the lawyer to record the method used, the date on which the document was delivered, the language supplied, the proof of receipt and the period allowed for the UK respondent to appoint a lawyer or respond. A UK spouse should not assume that the deadline for a respondent located in England or Wales is identical to the period that would apply to a respondent served in France. The GOV.UK family-law guidance should be checked alongside the applicable service rules.

Prepare the evidence in folders that match the legal questions. The first folder is identity and status: passports, all names used, marriage certificate, any prior divorce or civil-partnership documents and, where required, certified translations. The second is residence: leases, completion or sale records, utility bills, council-tax or French tax correspondence, residence cards, employment documents, pension statements, health records and school records. The third is family life: children’s addresses, school attendance, care calendars, travel records, medical decisions and messages concerning the separation. The fourth is finances: bank statements, payslips, tax returns, property valuations, mortgages, French and UK pension statements, business interests, trusts, inheritances and debts.

The evidence should be chronological, not merely voluminous. Create a table with date, event, country, document and legal purpose. For example, a French rental agreement may support a move; electricity bills may show occupation; a child’s school registration may support habitual residence; a UK employment contract may explain continuing UK ties; a tax return may corroborate but not determine the analysis. Never submit a bundle in which the same document appears under inconsistent dates or names without an explanation.

Residence evidence is only one part of the French jurisdiction test. The marriage certificate establishes the relationship but not the proper forum. A French property deed establishes ownership but not habitual residence. A French visa or Withdrawal Agreement card establishes an immigration position but not necessarily the centre of family life. Conversely, UK payslips do not prove that the UK spouse remained habitually resident there if the person actually lived in France. The court decides from the combined evidence.

The 2022 Cour de cassation decision, First Civil Chamber, 30 November 2022, no. 21-15.988, is useful for presenting this combination. The Court upheld the finding of French habitual residence after the lower court considered stable social life, ordinary spending and practical ties in France. The decision should not be quoted as a fixed checklist or as a post-Brexit rule. Its value is methodological: explain why each fact shows stability or why a competing UK fact does not displace the French centre of life.

Choose the legal ground for the divorce only after the forum and evidence review. French procedure recognises several forms of judicial divorce, including divorce accepted by both spouses, divorce for a permanent alteration of the marital relationship and divorce for fault. The factual and evidential requirements differ. A spouse who wants provisional housing, support or child measures should ask for them expressly and ensure that the application contains the mandatory information. Service-Public explains that the French judge can address the divorce itself and the consequences requested by the parties, including a compensatory payment, child residence and child support.

There are two important procedural safeguards for the UK spouse. First, keep the envelope, electronic notice, certificate of service and every translated page. The date of effective service can affect the response, the hearing and the appeal timetable. Secondly, if the service or jurisdiction is defective, raise the issue through the appropriate procedural channel and do so promptly. Waiting until the end of the case can weaken the argument, especially if the spouse has participated on the merits without reserving the objection.

Recognition questions can arise during the case, not only after judgment. In Cour de cassation, First Civil Chamber, 10 May 2007, no. 06-11.323, the Court held that le contrôle à titre incident de la régularité internationale d’un jugement étranger pouvant être opéré par tout juge, which means that a judge may incidentally examine the international regularity of a foreign judgment when that judgment is invoked to challenge the judge’s power to decide. The case concerned a Texas divorce, not a UK divorce. It remains a practical reminder to bring any earlier foreign judgment, settlement or divorce document to the lawyer’s attention at the start.

At the end of a French case, the judgment must be preserved in an authenticated form, with proof of service and any certificate showing whether an appeal has been brought. The civil-status consequences should also be addressed. Service-Public explains that the divorce must be recorded against the marriage record and, where the marriage took place abroad, that the Service central d’état civil may be involved. This administrative update is not the same as enforcing a money order in the UK. Keep a separate recognition and enforcement file.

B. How do French financial orders interact with UK pensions, property and enforcement?

Financial planning should begin before the French divorce petition. The most frequently misunderstood French concept is the prestation compensatoire, a compensatory payment intended to address the financial disparity created by the breakdown of the marriage. Article 270 of the Civil Code provides that divorce ends the duty of support between spouses and that one spouse may be required to pay a payment intended to compensate, as far as possible, the disparity in their respective living conditions. Légifrance states that the payment has a lump-sum character and is fixed by the judge. See Article 270 Code civil.

The exact wording matters. Article 270 says Le divorce met fin au devoir de secours entre époux; the French duty of support during marriage and the post-divorce compensatory payment are not identical. A British reader should not translate prestation compensatoire as though it were automatically an English maintenance order or a pension-sharing order. It may be a capital payment, and its purpose is to compensate a disparity, not to copy the English clean-break analysis word for word.

Article 271 sets out the factors for the amount. The judge considers the needs of the recipient and the resources of the other spouse at the time of divorce and in the foreseeable future. The list includes the duration of the marriage, age and health, professional qualifications and positions, career choices made during the marriage, property after liquidation of the matrimonial regime, existing and foreseeable rights, and the respective retirement positions. The official text begins: La prestation compensatoire est fixée selon les besoins de l’époux à qui elle est versée et les ressources de l’autre. Read Article 271 Code civil with the complete financial evidence, not with a headline calculator.

UK pensions must therefore be identified, valued and explained. List the State Pension position, workplace pensions, defined-benefit schemes, personal pensions, QROPS or overseas plans, AVCs and any pension already in drawdown. Record whether a statement gives a transfer value, annual income, accrued rights or only a forecast. A French court cannot assess a future retirement disparity from a vague reference to “my pension”. The valuation date and currency should be clear, and the parties should explain whether a right was built before, during or after the marriage.

The English and Welsh financial framework uses different instruments. The official GOV.UK guide on money and property after separation describes division of pensions, property, savings and investments, and explains that an agreed financial arrangement generally needs a consent order to become legally binding. An English pension-sharing order and a French compensatory payment may produce different administrative results. A French order may require cooperation from a UK pension provider, additional recognition proceedings or a separate English application. The agreement must say who pays, in what currency, on what date, with what security and what happens if the recipient lives in the UK.

Do not omit the matrimonial property regime. The regime is the legal system governing ownership and division between spouses. A French court may need to determine which law governs the regime, whether assets are common or personal, how a French home is treated, and how debts are allocated. That is not the same as the property purchase process, which belongs to a different legal workflow. Here the relevant task is to identify the existing asset, its financing, its ownership and its place in the financial consequences of divorce.

Also disclose inheritances and gifts. An inherited French property, UK trust interest or family gift may have a special character under the applicable matrimonial regime, but it can still affect the overall financial picture. Do not move an asset to a company, SCI or nominee merely to make it disappear from the schedule. The court and the other spouse may investigate the transaction, and a later enforcement dispute becomes much harder when the original ownership trail is incomplete.

Recognition and enforcement must be separated into at least three questions: recognition of the marital status, recognition of the financial obligation and practical enforcement against a particular asset. Article 509 of the French Code of Civil Procedure states that Les jugements rendus par les tribunaux étrangers et les actes reçus par les officiers étrangers sont exécutoires in France in the manner and cases provided by law. See the current Article 509 CPC. The wording itself points to the applicable treaty, European regime or domestic procedure; it is not a universal declaration that every foreign order is immediately enforceable.

For a post-Brexit UK judgment, the French route may involve recognition or an exequatur, meaning a French judicial decision giving a foreign judgment enforceable force in France. Service-Public explains that a civil decision made outside the European Union does not apply directly in France for enforcement and that the judge checks, among other matters, international jurisdiction, international public policy and absence of fraud. The English version of the official page is available under Execution of a foreign civil judgment in France. The exact route depends on the kind of order, the date proceedings began, any convention and whether the request concerns civil status or coercive execution.

French case law illustrates why the parts of a foreign decision must be read carefully. In Cour de cassation, First Civil Chamber, 4 November 2010, no. 09-15.302, the Court said that a Texas divorce judgment with an indivisible character ne peut être reconnu en France, que ce soit en totalité ou partiellement en ses seules dispositions financières where the judgment contained provisions contrary to fundamental principles. This does not mean that every UK order will fail. It means that a court may examine the judgment as a whole, the procedure, the relief granted, public policy and whether a proposed partial recognition has a sound legal basis.

Due process evidence is particularly important. In Cour de cassation, First Civil Chamber, 10 May 2006, no. 04-19.988, the Court accepted recognition of a Canadian divorce where the spouse had been regularly served and the foreign procedure was non-contradictory because that spouse failed to appear after proper service. The Court’s published reasoning states that the divorce based on la cessation de toute cohabitation entre les époux pendant plus d’un an was not, on those facts, contrary to French international public policy. The decision shows why service records, the foreign judgment and the opportunity to participate belong in the enforcement file.

An older authority should be handled with the same care. In Cour de cassation, First Civil Chamber, 19 January 1983, no. 81-16.159, the Court wrote that Une décision de divorce étrangère est dotée de plein droit d’efficacité en France, sous réserve de l’exécution forcée. That principle concerns the effect of a foreign divorce subject to the circumstances then examined and does not eliminate modern treaty, European, public-policy or enforcement analysis. A lawyer should never cite the sentence as a shortcut for a current UK financial order.

On the UK side, the official Family Law Act 1986 framework and the 1970 Hague Divorce Convention may be relevant to recognition of marital status, while maintenance and child orders can follow different Hague instruments or domestic routes. The HCCH Divorce Convention page explains that the 1970 Convention is intended to facilitate recognition of divorces and legal separations between contracting States. The current HCCH status table confirms the parties and declarations; do not assume that a convention on divorce status automatically enforces every pension or lump-sum provision.

A UK spouse who obtains or accepts a French divorce should ask whether all financial claims have actually been resolved. The UK maintains forms for applications for financial relief after an overseas divorce under the Matrimonial and Family Proceedings Act 1984. The official GOV.UK financial-remedy collection lists forms for permission and applications after an overseas divorce. This does not predict that an English court will make an order in a particular case, but it is a warning against signing a French divorce agreement that says nothing clear about UK pensions, English property or future financial claims.

Use a financial schedule that identifies each relief separately:

Issue	Question to answer before filing	Evidence to preserve
French divorce	Which court has jurisdiction, and what law governs the marital status?	Marriage certificate, residence chronology, service documents
Housing and interim support	Who occupies the home and who pays mortgage, rent, utilities and debts during the case?	Lease or title, loan statements, bills, payment history
Compensatory payment	Is there a disparity in future living conditions and what capital or income would address it?	Budgets, tax returns, income, health, career and pension evidence
UK pensions	Is the requested relief a French capital payment, a pension-sharing order or another mechanism?	State Pension record, scheme statements, transfer or cash-equivalent values
Children and maintenance	Which country can decide residence, contact and recurring support, and how will payment be enforced?	School, care, travel, income and existing order documents
Recognition	Will the order be used for civil status, voluntary payment or enforcement against an asset?	Certified judgment, proof of service, finality certificate and translation

The schedule should be updated whenever a new account, valuation or pension statement appears. A settlement is not safe merely because both parties sign it. Confirm that the lawyers have authority in the relevant jurisdictions, that the wording distinguishes divorce from financial relief, and that the mechanism for payment can work against an asset located in the UK or France. If the payment is in euros but the income is in pounds, add a currency and exchange-rate clause. If the payer dies, the French Civil Code has specific rules: Article 280 provides that, on the death of the debtor spouse, payment of the compensatory payment is taken from the estate within the statutory limits. See Article 280 Code civil.

The legal and practical conclusion is not that France or the UK is always better. It is that a France–UK divorce must be designed as one coordinated case even if different courts ultimately handle different issues. Establish the residence facts, check the two jurisdictional systems, protect the children, preserve service evidence and value the pensions before a final forum choice. A careful first filing can prevent a later argument that the court lacked jurisdiction, the spouse was not properly served, the settlement left a financial claim open or the judgment cannot be enforced where the money actually sits.

Conclusion

A French court may be able to divorce a British couple when one spouse lives in France and the other remains in the UK after Brexit. The decisive question is not the passport or the existence of a French second home. It is whether the French court has a valid jurisdictional connection, supported by a coherent chronology of habitual residence and family life. The JAF’s territorial allocation under Article 1070 CPC, the European grounds for a French court, the French conflict-of-laws rules and the UK’s post-Brexit domestic rules must be read together.

Do not file or sign a financial agreement before mapping the other forum. A French divorce, a prestation compensatoire, child arrangements, maintenance, UK pensions and enforcement may follow different rules. Keep the marriage, residence, service, children and financial evidence in separate but cross-referenced files. If the case has already started, preserve every date and obtain advice on jurisdiction, service and recognition immediately. The existing article on recognising a UK divorce in France addresses the reverse situation after a UK judgment; this article concerns the choice and preparation of a French forum before judgment.
