« Alexis, we live in Dubai, we married in London without a prenuptial agreement, and we own assets in France, Switzerland and Singapore. Today, we are separating. Which judge will rule? Which law will apply to our properties and financial portfolios? Can my spouse challenge the structure of my foreign trust? »
Divorce is a universal human ordeal, but when it takes on an international dimension, it shifts into extraordinary technical complexity. On foreign soil, a separation is no longer merely a matter of feelings or of the civil code; it is a conflict of legal sovereignties in which every decision can affect your financial future irreversibly. A cross-border estate that is poorly protected during a divorce can suffer massive erosion through contradictory laws or punitive taxation.
At Balmont Conseil, we act as the central pivot of your strategy. As an Augmented Wealth Engineer, I combine my expertise in private international law with the power of a super-trained wealth-management AI. This synergy enables us to decode bilateral conventions, to simulate the impact of the liquidation of assets across different jurisdictions, and to protect your assets with surgical precision.
What is an international divorce?
A divorce is deemed international as soon as it presents a "foreign element". This may be the nationality of the spouses (dual nationals), their place of residence (expatriates), or the geographical location of their cross-border estate (foreign accounts, foreign real estate, holding companies).
The main difficulty lies in disentangling two fundamental questions:
- Jurisdiction of the courts: Which judge has the power to grant the divorce? (The "Forum").
- The law applicable to the divorce: Which body of law must the judge apply to reach a decision? (The "Jus").
Jurisdiction of the courts
In an international divorce, the first instinct is often emotional, but the first act must be strategic. Determining which court has jurisdiction is a race against the clock to protect your assets.
-
The principle of habitual residence: Within the EU (Brussels II ter Regulation), it is the place of your daily life that prevails. If you live in Madrid, the Spanish judge is by default the most legitimate.
-
The "First to File" rule: This is the concept of Forum Shopping. The first spouse to file the petition in a competent country fixes the venue of the dispute.
-
What is at stake for your estate: A judge in Dubai or London will not take the same view of the division as a judge in Lyon. Seising the French court first may prove to be your best manoeuvre for protecting your estate.
The law applicable to the divorce
Once the judge has been designated, they must decide which laws to apply. A French judge may perfectly well apply Singaporean law if they consider it to be the law most closely connected to your matrimonial situation.
-
The Rome III Regulation: It allows expatriates to choose the applicable law (that of their nationality or of their residence). Without a prior written choice, it is the law of your current habitual residence that applies.
-
The trap of automatic mutability: This is the major risk for expatriates. Without a specific marriage contract, your matrimonial regime may "mutate" automatically towards that of your host country after a few years (The Hague Convention).
-
The Balmont expertise: We use our AI tools to simulate the impact of a change of law on your assets. Moving from a French separation of property to an Anglo-Saxon "Equitable Distribution" can halve your estate without your having anticipated it.
Alexis's advice: Do not simply submit to foreign law. A pre-expatriation audit (or a change of regime along the way) makes it possible to lock in the legal protection of your own separate property.
Determining the legal framework: Who decides and under which rules?
For couples connected to the European Union, the framework is largely harmonised, yet remains highly subtle. For others, one must navigate between the civil code and the bilateral tax conventions.
The jurisdiction of the judge (Where to divorce?)
The Brussels II bis Regulation (and now Brussels II ter) governs jurisdiction within the EU. In general, the competent judge is that of the spouses' habitual residence.
However, seising the judge is a strategic step: the first spouse to file the application can sometimes "fix" jurisdiction in one country rather than another (forum shopping).
The law applicable to the divorce (How to decide?)
The Rome III Regulation allows spouses to choose the law applicable to their divorce (for example, the law of their common nationality).
Failing such a choice, it is generally the law of the habitual residence at the time of filing that applies.
The liquidation of matrimonial regimes
This is where the shoe often pinches. The European Regulation of 24 June 2016 (2016/1103) allows spouses to choose the law applicable to their matrimonial regime.
Without an international marriage contract or choice-of-law clauses, it is the law of the first habitual residence after the marriage that often applies retroactively and automatically. This "automatic change of regime" is the principal trap of the cross-border estate.
The major challenges of wealth management in the event of a separation
During an international divorce, certain assets pose specific challenges that call for a thorough wealth audit from the very first signs of tension.
Anticipating and protecting: planning strategies
The best way to handle an international divorce is to have anticipated it, even if this may seem counter-intuitive at the time of the marriage deed.
What Balmont Conseil brings: human expertise combined with AI
Managing an international divorce without technological tools is like navigating without a compass in a storm.
Financial and legal modelling through AI
Our super-trained wealth-management AI is able to process massive volumes of data instantly: bilateral conventions, European regulations, and case law on trusts. Within minutes, we can simulate the financial outcome of a divorce depending on whether you seise the judge in London versus the judge in Paris.
Coordination of authentic deeds
We work in close collaboration with lawyers specialising in family law and with notaries to ensure that the authentic deeds (divorce agreements, liquidations) are drafted so as to be recognised everywhere. We pay particular attention to the exequatur process so that your rights are effective on the ground.
Mediation and dispute management
In an international context, judicial conflict is extremely costly and slow. We often favour divorce by mutual consent or wealth mediation. Thanks to our objective simulations, we help spouses find common ground on the liquidation of assets by demonstrating mathematically the value of an amicable settlement over an uncertain trial.
Practical advice for expatriate families
If you are in a situation of tension or if you are planning a move, here are our recommendations:
- Keep your evidence: Retain a record of the origin of the funds (inheritance, savings before the marriage) to prevent them from being "melted" into the community estate during the liquidation.
- Check your marriage deed: What was your first common domicile? It is often that which, by default, dictates your current property rules.
- Beware of divorce by mutual consent "without a judge": Although very convenient in France, divorce by lawyers' deed is not recognised by every country (particularly outside the EU). For an expatriate, appearing before a judge is sometimes necessary to guarantee the enforcement of the divorce decision abroad.
- Protect the reserved portion of the estate: In some countries, testamentary freedom is total. A divorce can thus disinherit your children from the succession if you have not put in place robust estate planning.
