«Alexis, we live in Dubai, we were married in London without a prenuptial agreement, and we own assets in France, Switzerland, and Singapore. Today, we are separating. Which judge will decide? Which law will apply to our apartments and financial portfolios? Can my spouse challenge the structure of my foreign trust?»

What is an international divorce?
A divorce is considered international when it involves a "foreign element". This can be the nationality of the spouses (dual nationals), their place of residence (expatriates), or the geographical location of their cross-border wealth (foreign accounts, real estate abroad, holding companies).
The major difficulty lies in the dissociation between two fundamental questions:
- The jurisdiction of the courts: Which judge has the power to pronounce a divorce? (The "Forum").
- The law applicable to divorce: Which code of law should the judge use to decide? (The "Judgment").

The jurisdiction of the courts
In an international divorce, the first reaction is often emotional, but the first step must be strategic. Determining which court has jurisdiction is a race against time to protect your assets.
The principle of habitual residence: Within the EU (Brussels II ter Regulation), the place of your daily life takes precedence. If you live in Madrid, the Spanish court is by default the most legitimate.
The "First Seized" rule: This is the concept of Shopping Forum. The first spouse to file the request in a competent country determines the place of the dispute.
The stakes for your assets: A judge in Dubai or London will not have the same view of inheritance division as a judge in Lyon. Filing a claim with the French courts first may prove to be your best strategy for protecting your assets.
The law applicable to divorce
Once a judge is appointed, they must decide which laws to apply. A French judge may very well apply Singaporean law if they deem it the most relevant to your marital situation.
The Rome III Regulation: It allows expatriates to choose The applicable law (that of their nationality or residence). Without a prior written choice, the law of your current habitual residence applies.
The trap of automatic mutability: This is the major risk for expatriates. Without a specific marriage contract, your matrimonial property regime can automatically "transform" into that of your host country after a few years (Hague Convention).
Balmont's expertise: We use our AI tools to simulate the impact of a change in the law on your assets. Switching from a French separation of property regime to an Anglo-Saxon "Equitable Distribution" regime could halve your wealth without you having anticipated it.
Alexis's advice: Don't be subject to foreign law. A pre-expatriation audit (or a change of regime along the way) allows you to legally secure the protection of your personal assets.
Determine the legal framework Who decides and according to what rules?
For couples within the European Union, the framework is largely harmonized, but remains highly nuanced. For others, it is necessary to navigate between the civil code and the... bilateral tax treaties.
The judge's jurisdiction (Where to get a divorce?)
THE Brussels II bis Regulation (and now Brussels II ter) governs jurisdiction within the EU. Generally, the competent court is that of the spouses' habitual residence.
However, the referral to the judge is a strategic step: the first spouse to file the application can sometimes "determine" jurisdiction in one country rather than another (the shopping forum).
The law applicable to 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).
In the absence of a choice, the law of habitual residence at the time of referral generally applies.
The liquidation of matrimonial property regimes
This is where the problem often lies. The European regulation of June 24, 2016 (2016/1103) allows couples to choose the law applicable to their matrimonial property regime.
Without international marriage contract Or choice of law clauses, It is the law of the first habitual residence after marriage that often applies retroactively and automatically. This "automatic change of regime" is the main pitfall of cross-border wealth.

- Keep your evidence: Keep track of the origin of the funds (inheritance, pre-marital savings) to prevent them from being "melted" into the common pool during liquidation.
- Check your marriage certificate: What was your first shared residence? It is often this that dictates your current property rules by default.
- Beware of divorce by mutual consent "without a judge": Although very practical in France, divorce by mutual consent through lawyers is not recognized by all countries (particularly outside the EU). For an expatriate, a court appearance is sometimes necessary to ensure the enforcement of the divorce decree. divorce decision abroad.
- Protect the inheritance reserve: In some countries, testamentary freedom is absolute. A divorce can therefore exclude your children from the inheritance if you have not put a will in place. estate planning robust.
