Key points

In an international divorce involving substantial wealth, the first question is not how assets will be divided. It is which authorities may decide each issue, which law applies and how proceedings and assets across several countries should be coordinated. Early analysis can reduce legal conflict, protect business continuity and contain financial and reputational risk.

• Jurisdiction over divorce, parental responsibility, maintenance and matrimonial property may follow different rules.
• Habitual residence, nationality, the date of marriage and existing agreements can materially change the analysis.
• Family businesses, overseas real estate, trusts, foundations, investment portfolios and valuable movable assets require coordinated advice.
• Legitimate wealth protection is preventive, transparent and consistent with the rights of spouses, children, creditors and public authorities.

Why international divorce requires a different approach

A family may live in Milan, own property in London and Switzerland, hold operating companies through a Luxembourg structure and use a trust governed by the law of a non-EU jurisdiction. In that situation there is rarely one single “divorce law”. Different rules may govern dissolution of the marriage, financial claims, matrimonial property, parental responsibility, maintenance, succession, company interests and tax consequences.

European instruments harmonise important parts of the framework, but they do not remove every difference between national systems. Not every country participates in the same instruments, and assets outside the European Union may require local advice and enforcement steps. A sound strategy therefore begins with a complete map of the people, assets, liabilities, structures and jurisdictions involved.

Which court may hear the divorce

Jurisdiction does not necessarily follow the place of the wedding or the nationality shown on a passport. The spouses’ habitual residence, their last common habitual residence, the respondent’s residence and other connecting factors may be relevant. Within the European Union, Regulation EU 2019/1111 governs jurisdiction and the recognition and enforcement of decisions in matrimonial matters and parental responsibility.

This analysis should take place before parallel proceedings begin. Timing and sequence can affect procedural efficiency and the availability of interim measures. The purpose is not to select a forum without a proper legal basis, but to identify the competent court and understand the legitimate practical consequences of proceeding in one jurisdiction rather than another.

Which law governs matrimonial property

The competent court and the applicable law are separate questions. An Italian court may have to apply foreign law, while a foreign court may need to consider assets or agreements connected with Italy. For matrimonial property regimes, Regulation EU 2016/1103 establishes rules on jurisdiction, applicable law and the recognition and enforcement of decisions in participating Member States.

The date of the marriage, the spouses’ first common habitual residence, nationality and a valid choice of law may all be relevant. Prenuptial and postnuptial agreements must be tested for formal and substantive validity, governing law and likely recognition in every material jurisdiction. An agreement that is valid in one country does not automatically have identical effects in another.

Assets that require particular care

Family businesses and company interests

For founders and business-owning families, economic value cannot be read from the nominal shareholding alone. Voting rights, shareholders’ agreements, transfer restrictions, dividends, shareholder loans, options, carried interest and the founder’s personal contribution may all matter. An uncoordinated family dispute can disrupt governance, financing, a sale process or succession planning.

Real estate in several countries

Real estate is also governed by mandatory rules in the country where it is located. Legal title, mortgages, ownership rights, taxation and enforcement must be checked locally. A family-law decision may require additional steps before it can produce practical effects against foreign property.

Trusts foundations and fiduciary structures

A trust does not automatically place wealth beyond the scope of divorce proceedings. The governing law, purpose, powers retained by the settlor, the position of beneficiaries, the timing of settlement, later contributions and actual administration are relevant. Foundations, insurance wrappers and fiduciary arrangements likewise require a fact-specific analysis based on substance and documents.

Investment portfolios and valuable movable assets

Bank accounts, securities, private equity interests, art, jewellery, yachts and aircraft raise issues of location, valuation, liquidity and provenance. Current inventories, independent valuations and a reliable documentary trail can significantly reduce disputes over ownership and value.

Lawful wealth protection and its limits

Wealth protection does not mean concealing assets, creating opacity or defeating established rights. Transactions carried out when a marital breakdown is foreseeable may be challenged and, depending on the facts and the jurisdiction, may have civil, tax or criminal consequences. Responsible planning is undertaken early, for genuine purposes and with coherent records.

Appropriate tools may include a suitable matrimonial property regime, agreements that comply with the relevant laws, corporate governance, shareholders’ arrangements, succession planning, insurance and ownership structures. No tool should be considered in isolation. Family, corporate and tax advisers in the relevant jurisdictions need a consistent factual and documentary basis.

Children privacy and reputation

For families with substantial wealth or a public profile, the objective is not limited to a financial outcome. Children should be protected from the dispute, the family business should remain operational and sensitive information should circulate only where necessary. Negotiation, collaborative approaches or mediation may be considered where appropriate to the case and compatible with the safety of the parties.

Confidentiality is never absolute. Court procedures, anti-money-laundering duties, tax reporting and lawful requests from authorities may require disclosure. It is therefore sensible to establish an information protocol at the outset: who may access documents, which advisers are involved, how data will be stored and how internal and external communications will be handled.

A pre litigation checklist

1. Record the spouses’ and children’s habitual residences, nationalities and relevant moves.
2. Prepare a jurisdiction-by-jurisdiction map of assets, liabilities, companies and fiduciary structures.
3. Collect marriage agreements, choices of law, wills, powers of attorney, shareholders’ agreements and trust documents.
4. Verify beneficial ownership, source of assets, contributions, security interests and transfer restrictions.
5. Identify the potentially applicable rules for divorce, children, maintenance and matrimonial property.
6. Coordinate lawyers, tax advisers, valuers, trustees and corporate advisers under one documentary strategy.
7. Assess the need for interim protection, the risk of asset dissipation and the effect of conflict on governance.
8. Define realistic objectives, family priorities and confidentiality standards before negotiations begin.

When to seek coordinated advice

Advice is particularly valuable before marriage, an international relocation, the acquisition of foreign property, a corporate reorganisation or an intergenerational transfer. If a relationship is already under strain, early advice helps preserve documents, avoid inconsistent steps and build a coherent strategy across the jurisdictions involved.

Every matter depends on the family structure, the nature of the assets and the countries concerned. There is no universal structure that protects every family. Effective planning comes from coordinating family law, private international law, ownership and governance, succession and tax advice.

Frequently asked questions

Where can an international divorce be filed?

The answer depends primarily on the jurisdiction rules that apply, often including habitual residence and, in some circumstances, nationality. The place of the wedding alone does not necessarily determine the competent court.

Will Italy recognise a foreign prenuptial agreement?

Not automatically. The governing law, form, content, circumstances of execution and compatibility of the requested effects with the relevant legal system must all be considered.

Does a trust always protect assets on divorce?

No. The governing law, structure, effective powers, beneficiaries, timing and purpose of transfers all matter. The trust must be analysed alongside the facts and the laws of the relevant jurisdictions.

Can a family company be affected by a divorce?

Yes, directly or indirectly. The value of shares, economic flows, governance rights, guarantees and shareholder arrangements may all be relevant. Business continuity should form part of the legal strategy.

Can a high net worth divorce remain private?

Exposure can often be reduced through disciplined information management and, where suitable, negotiation or mediation. Legal, procedural, tax and anti-money-laundering obligations still apply.

When should a family begin wealth planning?

Before a foreseeable dispute. Marriage, international relocation, a corporate reorganisation and succession planning are particularly important review points.
