Protecting Your Assets Before Marriage Abroad: Prenuptial Agreements and Financial Planning

Marriage has profound financial implications. In many legal systems, it automatically changes the ownership of assets acquired during the marriage, may impose obligations on assets held before the marriage, and creates claims on pensions, businesses, and inherited wealth in the event of divorce. For internationally mobile HNW individuals — particularly those with significant pre-marital wealth, business interests, or complex multi-jurisdictional assets — pre-marital financial planning is a prudent and increasingly common step.

This guide covers prenuptial agreements, jurisdiction shopping, community property regimes, and the practical steps individuals should take before entering into marriage in a different country.

Why Pre-Marital Financial Planning Matters

The financial risks of marriage depend significantly on which country's law governs your matrimonial finances. Common law countries (including England and Wales, Australia, and the US) and civil law countries (most of continental Europe, many Asian countries) take fundamentally different approaches:

Common law jurisdictions generally do not automatically change the ownership of assets held before or during marriage, but courts have broad discretion on divorce to redistribute assets in a way that achieves "fairness" — which may include pre-marital assets, inherited wealth, and business interests.

Civil law jurisdictions with community of property (France, Spain, Belgium, many Latin American countries) typically apply a system under which assets acquired during the marriage are automatically jointly owned, regardless of who acquired them. Some regimes extend this to pre-marital assets.

Separate property regimes (common in Germany, some US states, and others) keep marital assets separate unless parties elect otherwise — more protective of individual wealth but still subject to maintenance and support obligations.

Understanding which regime applies to your marriage requires knowing which country's law will govern it — which may not be obvious if you and your partner are of different nationalities, live in different countries, or move during the marriage.

Prenuptial Agreements: Do They Work?

A prenuptial agreement (prenup) is a contract entered into before marriage setting out how assets will be divided in the event of separation or death. Their enforceability varies significantly by jurisdiction:

England and Wales. Prenuptial agreements are not automatically binding but are afforded significant weight by English courts following the Supreme Court decision in Radmacher v Granatino (2010). A prenup will be upheld if:

• Both parties received independent legal advice before signing
• Both parties made full financial disclosure
• There was no undue pressure or coercion
• The agreement was entered into more than 21–28 days before the wedding
• The terms are not "manifestly unfair" (particularly regarding children's financial needs)

Even a well-drafted English prenup is not a guarantee — courts retain discretion. But a properly executed prenup significantly influences the outcome.

Scotland. Prenuptial agreements are enforceable in Scotland provided they meet general contract law requirements. Scotland has a more codified matrimonial property regime (under the Family Law (Scotland) Act 1985) which makes the starting point somewhat clearer than in English law.

European Union. EU Regulation 2016/1103 on matrimonial property regimes (applicable in 18 EU member states) allows couples to choose the law of either party's nationality or habitual residence to govern their matrimonial property. This "choice of law" approach gives internationally mobile couples considerable flexibility to select the most favourable regime.

United States. Prenuptial agreements are enforceable in all US states, subject to individual state requirements. California and New York have specific statutory frameworks.

UAE (Dubai/DIFC). Marriages contracted in the UAE are governed by UAE personal status law or, for non-Muslim expats in the DIFC or ADGM, potentially by the DIFC's own family law framework. Prenuptial agreements are recognised within the DIFC framework; outside it, the position is more nuanced.

Protecting Specific Asset Classes

Business interests. A business interest is among the most contentious assets in a divorce. In England and Wales, courts will typically "ring fence" a business from division only partially — the court considers all assets available to meet the parties' reasonable needs. A prenup that ring-fences a business can significantly reduce risk, but must be accompanied by clear documentation of what was brought into the marriage and what is separate from the matrimonial asset pool.

Inherited wealth. Inheritances received before or during a marriage are not automatically excluded from division under English law — courts treat them as a "non-matrimonial asset" that should be excluded from division in theory, but which in practice may be included if the marriage was long, if the assets were "mingled" with matrimonial assets, or if the overall settlement would otherwise be inadequate. Keeping inherited wealth in separate accounts and not using it for joint purposes (buying a family home, for example) preserves its "non-matrimonial" character.

Pension assets. Pension sharing orders can be made against defined benefit and defined contribution pensions on divorce in the UK, regardless of when the pension was accrued. Offshore pensions (QROPS, for example) may be more difficult to share but are not immune from court orders if sufficient other assets are available.

Property abroad. The treatment of foreign property depends on the law of the country where it is located, not just the law governing the marriage. Real property in France is governed by French law; in Spain by Spanish law. A prenup under English law may not be effective against claims on a Spanish apartment.

Financial Disclosure: The Foundation

Any prenuptial agreement requires full financial disclosure from both parties. Without it, the agreement is vulnerable to challenge. Financial disclosure should include:

• All assets (property, investments, pensions, business interests, cash)
• All liabilities (mortgages, loans, tax obligations)
• Income from all sources
• Expected future wealth (inheritances, vesting share awards, business exit proceeds)

Partial or inaccurate disclosure undermines the validity of the agreement. This is not a tick-box exercise — it requires honesty about the full financial picture.

International Marriages: Choosing Your Law

For internationally mobile couples, the question of which country's law governs the marriage is not automatically answered. Factors that influence governing law include:

• The country where the marriage is contracted
• The habitual residence of the parties during the marriage
• The nationality of the parties
• In the EU, any explicit choice of law election

A choice of law clause in a prenuptial agreement can specify which country's matrimonial property regime applies. This requires legal advice from specialists in both jurisdictions.

Steps to Take Before Marriage Abroad

1. Take independent legal advice from a family law specialist in the country where you plan to marry and in your country of domicile
2. Prepare a full, documented list of pre-marital assets
3. Ensure inherited assets are clearly documented as gifts or inheritances (keep letters, deeds of gift, grant of probate documentation)
4. Consider ring-fencing pre-marital assets in separate accounts or structures
5. Discuss and agree a prenuptial agreement well before the wedding (21–28 days minimum in England and Wales)
6. Ensure both parties have independent legal advice
7. Keep the prenuptial agreement under review — particularly if the marriage lasts more than ten years or if financial circumstances change materially

The Conversation

Pre-marital financial discussions can feel uncomfortable. But they are the foundation of a financially healthy marriage. Couples who discuss their financial positions, expectations, and plans before marriage — including what would happen in the event of separation — tend to handle financial matters better during the marriage itself. The prenup conversation, approached constructively, is as much about creating financial clarity as about protection.
