Getting Married Abroad: Financial Planning and Legal Considerations

Getting married abroad is increasingly common — particularly among internationally mobile couples who have a meaningful connection to multiple countries, who want to marry in a destination that is special to them, or who are expats living outside their home country. For such couples, the financial and legal dimension of an overseas marriage deserves as much careful planning as the ceremony itself.

This guide covers the legal recognition of overseas marriages, the financial implications of marriage for internationally mobile individuals, and the estate planning and tax steps that should follow any marriage.

Nothing in this article constitutes legal advice. Marriage laws and financial regulations vary significantly by country. Seek independent legal and financial advice specific to your circumstances.

Legal Recognition of an Overseas Marriage

The starting point is ensuring the marriage is legally valid — both in the country where you marry and in your home country (or countries of nationality/residence).

England and Wales recognition. A marriage is generally recognised as valid in England and Wales if it was entered into in accordance with the laws of the country where it took place, and the couple were free to marry under English law (i.e., not already married, of sufficient age, and not within prohibited degrees of relationship). This covers the vast majority of overseas marriages in standard civil ceremonies.

Common exceptions and pitfalls:

• Religious-only ceremonies. Certain religious marriages (including some Islamic nikah ceremonies, Hindu ceremonies, or Jewish ceremonies in some countries) may not be automatically recognised as civil marriages in England. A separate civil ceremony or registration may be required.
• Same-sex marriages. Not all countries recognise same-sex marriage. A same-sex marriage conducted in a country that does not recognise it may still be valid in England if the couple intended to marry and met the requirements. Specific legal advice is important for same-sex couples marrying in jurisdictions with complex position.
• Customary marriages. Indigenous customary marriages (common in parts of Africa, Asia, and the Pacific) may require additional steps for recognition.
• Proof of marriage. Obtain multiple certified copies of the marriage certificate and, if necessary, apostille authentication (certification for international use under the Hague Convention) and certified translation into English.

It is strongly advisable to check with a UK solicitor whether a planned overseas marriage will be fully recognised in England before the ceremony.

Tax Implications of Marriage

UK Tax Changes

Marriage triggers a number of UK tax changes:

Transfers between spouses. Transfers of assets between UK-resident spouses are made on a no-gain/no-loss basis for CGT purposes. This allows tax-efficient rebalancing of asset ownership between spouses — for example, transferring income-producing assets to a lower-rate taxpaying spouse.

Marriage Allowance. If one spouse does not use their personal allowance, they can transfer £1,260 of their allowance to the other spouse (2026 figure, subject to change), saving up to £252 per year in income tax. Available where neither spouse pays higher-rate tax.

Inheritance Tax exemption. Transfers between spouses are normally IHT-exempt without limit. Since 6 April 2025 the UK IHT regime is residence-based rather than domicile-based: where the transferring spouse is a long-term UK resident but the recipient spouse is not, the lifetime exempt amount is capped at the nil-rate band (£325,000 as of 2026/27), unless the recipient elects to be treated as a long-term UK resident. (Before 6 April 2025 this restriction was framed by reference to domicile.)

Residence nil-rate band. The residence nil-rate band (currently £175,000 per person) is transferable between spouses on death, effectively doubling it for married couples.

Pension benefits. Most pension schemes treat a surviving spouse as a primary beneficiary. Marriage creates an entitlement to survivor's pension in most defined benefit schemes. For personal pensions (SIPPs), the Expression of Wish form should be updated.

Tax in the Country of Marriage or Residence

For couples where either partner is resident in a non-UK country, the tax implications of marriage in that country also apply:

• UAE: No income tax; marriage in the UAE of different nationalities can have implications for inheritance under local law.
• Spain: Marriage triggers a community property default regime unless a prenuptial agreement specifying separation of assets is made before a Spanish notary.
• France: Similar community property principles apply.
• Singapore and Hong Kong: Common law influenced, broadly similar to England in approach.
• Cyprus: Statutory inheritance rights of a surviving spouse are established.

The interaction between two countries' tax and succession systems — particularly where spouses are nationals of different countries living in a third country — is complex. Professional legal and financial advice covering all relevant jurisdictions is essential.

Pre-Nuptial Agreements

Pre-nuptial agreements are discussed in detail in our article on cross-border divorce planning. For internationally mobile couples, the key points are:

• Pre-nuptial agreements are not automatically binding in England and Wales but carry significant weight following Radmacher v Granatino [2010].
• They are particularly valuable where parties have significant pre-marital wealth, substantial inheritance expectations, children from a previous relationship, business interests, or very different nationalities and domiciles.
• An agreement must be made in advance (not immediately before the wedding), with both parties having independent legal advice and full disclosure of financial circumstances.
• International pre-nuptial agreements should specify governing law and jurisdiction.

In Spain and France, a pre-nuptial agreement before a notary establishing a separation of property regime is the normal approach and is legally straightforward. In common law jurisdictions, the position is more nuanced.

The absence of a pre-nuptial agreement is not a problem in itself, but for couples with complex financial positions, the security it provides is valuable.

Financial Account Updates After Marriage

Following marriage, a significant number of financial accounts and documents need to be updated:

Name changes (where applicable). If either spouse is taking the other's name, all financial accounts, passport, national insurance records, HMRC, pension schemes, insurance policies, driving licence, and banking relationships need to be updated.

Joint accounts. Many couples choose to open joint accounts for shared expenditure. This is a practical step but has financial planning implications: joint accounts give each party full access to the balance, which may not always be appropriate. Consider carefully which accounts should be joint and which should remain separate.

Beneficiary designations. Life insurance policies, pension schemes, and investment accounts with nominated beneficiaries should be updated to reflect the new spouse.

Life insurance. If a new spouse becomes financially dependent on your income, adequate life insurance must be in place. Similarly, income protection cover should be reviewed with the new household financial structure in mind.

Estate Planning: The Most Urgent Post-Marriage Priority

Marriage in England and Wales revokes any existing will. This means that if you made a will before marriage and do not update it, you will die intestate (as though you had no will). Under intestacy rules, a surviving spouse would receive: all personal property and the first £322,000 of the estate (subject to government review), with the remainder split equally between the spouse and children (if any). This may not be what you intended.

Action required: Make a new will immediately after marriage. If you are an expat with assets in multiple countries, ensure wills in all relevant jurisdictions are updated.

Additional estate planning steps:

• Update Lasting Power of Attorney to include the new spouse where relevant (or establish one if you do not have it)
• Review trust structures to confirm the new spouse is appropriately considered
• Review pension Expression of Wish forms for each pension scheme
• Review IHT planning in light of the spousal IHT exemption
• If either party has children from a previous relationship, ensure their interests are properly protected in the revised estate plan

Financial Goals and Integrated Planning

Marriage is also an opportunity to align financial goals as a couple. Steps include:

Creating a shared financial plan. What are your combined goals? Retirement age, desired income, property plans, educational aspirations for children, international mobility plans? These may have been planned individually and now need to be integrated.

Income and tax planning. Who earns more? Are assets held in the most tax-efficient ownership between spouses? Is it worth transferring income-producing assets to the lower-rate taxpayer?

Protection review. With two people now financially interdependent, what happens financially if one of you is seriously ill, unable to work, or dies? Review life insurance, critical illness cover, and income protection as a household.

Pension planning. Both spouses should have adequate pension provision. If one partner's career has been less continuous (career breaks, childcare, international relocation), pension catch-up strategies may be needed.

Considerations for Couples of Different Nationalities

Where spouses are nationals of different countries, the legal and financial complexity is amplified:

• Residence and domicile. Since 6 April 2025, UK inheritance tax exposure turns principally on long-term UK residence (UK-resident in 10 of the last 20 tax years) rather than on domicile. Domicile still matters for some succession and matrimonial-property questions and depends on origin, intention, and the rules of the countries involved. Marriage itself does not automatically change domicile.
• Wills. Multiple wills covering each country of asset-holding are typically required. These must be co-ordinated to avoid conflict.
• Inheritance law. Where one spouse is an EU national, the EU Succession Regulation may allow election of the law of that nationality to govern their EU estate. UK nationals cannot use this regulation post-Brexit.
• Divorce risk. The jurisdiction in which divorce proceedings are issued has enormous financial consequences. A pre-nuptial agreement with governing law and jurisdiction specified is valuable for international couples.
