For British expats and couples whose lives cross borders, divorce can become genuinely complicated – different countries, different laws, and assets in more than one place. A prenup is a valuable way to bring certainty to all of that, but international couples need to think carefully about one issue above all: jurisdiction. This guide explains why jurisdiction matters, how a prenup helps, and why you may need advice in more than one country.
Why jurisdiction matters most
For an international couple, the single most important question is jurisdiction: which country’s courts would deal with a divorce, and whose law would apply. This can change the outcome dramatically – some countries share assets very differently from England & Wales, and some give a prenup automatic binding force while others give it little weight. Worse, it is not always obvious in advance where a divorce would be heard: couples with international lives can find themselves facing proceedings in a country they did not expect. Getting clarity on this early is the heart of expat planning – see who should consider a prenup.
How a prenup helps an international couple
A prenup lets you set out your intentions clearly, which is valuable wherever the divorce ultimately happens. If your case is dealt with in England & Wales, a fair agreement made properly carries significant weight (see are prenups legally binding?), and it should address assets held in more than one country (see overseas assets and what to include). Even where another country hears the case, a clear written record of what you both intended can be persuasive.
Assets in more than one country
Expats often hold property, accounts, pensions or investments across several jurisdictions. A prenup should cover them all, with honest disclosure of assets wherever they sit. Different countries treat property, pensions and matrimonial regimes very differently, so listing everything clearly – and noting where it is held – makes the agreement far more useful if it is ever needed.
Take local advice too – and consider a mirror agreement
Because an English-law prenup may not be automatically recognised abroad, it is often worth taking advice in the other country as well, and sometimes putting a matching ("mirror") agreement in place there so your intentions are respected in both systems. This is closely related to the wider questions in our jurisdiction guides – see will a UK prenup be recognised abroad?, do foreign prenups work in the UK? and, where one partner is not British, prenups with a foreign spouse.
Prenups for expats: why jurisdiction is everything
For expats, the single most important issue is jurisdiction – which country’s courts would handle a divorce, and whose law applies. That can change the outcome dramatically and is not always obvious. An English-law prenup carries weight if your case is dealt with in England & Wales and should cover assets in each relevant country; but because it may not be recognised automatically abroad, taking advice in the other country – and sometimes a mirror agreement there – is the safest approach.
Matrimonial property regimes abroad
Many countries operate a "matrimonial property regime" – a default set of rules about how a married couple’s assets are owned and shared, sometimes chosen at the point of marriage. This is quite different from the discretionary system in England & Wales, and it means an agreement drafted for one system may not translate neatly to another. If you have lived, married or hold assets in a country with such a regime, it is important that your English prenup and any overseas arrangement are consistent rather than contradictory (see do foreign prenups work in the UK?).
Moving countries during the marriage
Expat life is mobile, and where you live can change more than once. A move can shift which country’s courts would deal with a future divorce, so an agreement that made perfect sense when you signed it may need revisiting after a relocation. Building in a review clause – and taking fresh local advice when you move – keeps your planning aligned with your actual life (see will a UK prenup be recognised abroad?).
Why England is called the "divorce capital"
It is worth understanding why jurisdiction is such a high-stakes question for international couples. England & Wales has a reputation as one of the more generous jurisdictions for the financially weaker spouse, thanks to its discretionary system, its emphasis on meeting needs and its willingness to share wealth and award maintenance. Some other countries apply fixed matrimonial property regimes that divide assets quite differently, and many give a properly made prenup automatic binding force – something England & Wales still does not do, even after Radmacher v Granatino (2010) (see are prenups legally binding?). The result is that where a divorce is heard can change the outcome dramatically, and couples with lives spanning two countries may have a genuine choice – or a genuine fight – about it.
A worked example
Imagine a British couple who marry in London, sign an English prenup, then move to a country with a community-property regime for a decade before returning. If they divorce, the two systems could reach very different answers, and there may be argument about which court has jurisdiction. An English prenup will carry real weight if the case is heard here; a matching agreement made in the other country improves the odds that their intentions are respected there too. Disclosing and listing assets in every country – the London flat, the overseas home, pensions in both places – is essential (see overseas assets). This is why cross-border couples so often need advice in more than one jurisdiction.
Mirror agreements and keeping them aligned
The safest approach for a strongly international couple is often a pair of consistent agreements – an English prenup and a "mirror" agreement in the other relevant country – drafted so they say the same thing rather than contradicting each other. This takes coordinated advice, but it means your intentions have the best chance of being honoured wherever a divorce is dealt with (see will a UK prenup be recognised abroad? and do foreign prenups work in the UK?). Because expat life is mobile, a review clause – and fresh local advice whenever you relocate – keeps the whole arrangement aligned with where you actually live.
Visas, residence and a foreign spouse
International couples often have an immigration dimension as well as a financial one, and the two can interact. Where one partner has come to the UK on a spouse visa, or where a British expat has married someone with a different nationality, questions of residence and domicile can influence both where a divorce could be heard and how assets are treated. A prenup does not decide immigration status, but it can bring welcome clarity to the money side while those questions are live (see prenups and a spouse visa and prenups with a foreign spouse). If you married overseas, it is also worth checking how that marriage and any agreement made around it are viewed here (see married abroad).
Language, translation and genuine understanding
Where partners have different first languages, a practical point matters more than it first appears: both must genuinely understand what they are signing. An agreement one partner did not truly comprehend is vulnerable to challenge, so a properly translated version, and independent advice each partner can follow in their own language, are worth the effort. This ties back to the core requirement from Radmacher v Granatino (2010) that each party entered the agreement freely and with a full appreciation of its implications – harder to show if a language barrier obscured the terms (see independent legal advice).
Common mistakes for cross-border couples
The most common mistake is assuming an English prenup will automatically be honoured everywhere – it will not, and recognition varies widely between countries. A second is failing to list assets held abroad, on the mistaken belief that only UK assets "count"; full disclosure means everything, wherever it sits (see overseas assets). A third is signing an agreement and never revisiting it despite moving country two or three times over a career. A review clause, and fresh local advice on each relocation, keeps the arrangement aligned with where your life actually is.
Expat prenup FAQs
Will a UK prenup work if we live abroad?
It depends on where any divorce is dealt with and whose law applies (see will a UK prenup be recognised abroad?).
Do expats need an agreement in two countries?
Often advisable where there are strong overseas ties, to cover both legal systems (see do foreign prenups work in the UK?).
My partner is not British – does that change things?
It can affect jurisdiction and recognition; specialist advice helps (see prenups with a foreign spouse).
Should a prenup list our overseas assets?
Yes – disclose and cover assets wherever they are held (see overseas assets).
Is an English prenup binding abroad?
Not automatically – recognition varies by country, so local advice matters (see are prenups legally binding?).
Does my partner’s spouse visa affect our prenup?
A prenup does not decide immigration status, but residence and domicile can affect jurisdiction, so it is worth taking joined-up advice (see prenups and a spouse visa).
We married abroad – can we still make an English prenup?
Yes, though how the overseas marriage and any agreement are viewed here should be checked (see married abroad).
