We Scots have a reputation as being pretty friendly and hospitable, and it looks like the impression the Tartan Army made in Boston and Miami during the 2026 FIFA World Cup has helped to cement that global reputation. Our International Families Team here at Thorntons has helped many US citizens relocate to Scotland over the last few years, and whilst relocating to another country is exciting, it can raise important legal questions particularly around family law. If you and your spouse signed a prenuptial agreement (commonly known as a ‘prenup’) in the United States and are now planning a move to Scotland, you may be wondering whether that agreement will still stand and be enforceable.
If you separate after you have moved to Scotland, the Scottish courts will likely have authority to deal with your divorce, the level of financial support that can be paid, and the issues of how assets can be divided, known here as financial provision. As a general rule, the Scottish courts will recognise and enforce prenuptial agreements that are deemed to have been fairly entered into, but there are important nuances to understand.
Will a U.S. prenuptial agreement be recognised in Scotland?
There is no blanket rule in Scotland that automatically recognises or rejects a foreign prenuptial agreement. If your marriage were to end while you are living in Scotland, the Scottish court would assess your prenuptial agreement under Scottish legal principles, rather than deferring to U.S. law.
This means that even though your agreement might be valid under the law of the U.S. state where it was signed, a Scottish court will apply its own standards when deciding how much weight to give it.
How does Scots Law treat prenuptial agreements?
Scotland treats prenuptial agreements in a notably contract-friendly way. Scottish courts regard these agreements as enforceable contracts, not merely guides for the court to consider. In colloquial terms, Scots law recognises the rights of adults to regulate their own affairs, and enter into, and be bound by, agreements even if they do not provide an outcome consistent with what like a court might award. In the words of Lord Reed, prenuptial agreements in Scotland are “construed and enforced on precisely the same principles as any commercial agreement.”
However, enforceability is not absolute. Under the Family Law (Scotland) Act 1985, on the application of a spouse, a court may set aside or vary a prenuptial agreement if it was “not fair and reasonable at the time it was entered into.” This is the lens that a Scottish court will consider the agreement through.
The “Fair and Reasonable” Test
So, what does “fair and reasonable” mean? In this context, the court examines all the circumstances surrounding the making of the agreement. Scottish courts have stated that they should not be “unduly ready” to overturn agreements validly entered into, and an unequal division of assets does not, by itself, make an agreement unfair. Several factors will be closely examined:
- Independent legal advice: did each party receive their own legal advice before signing? While not an absolute requirement in Scotland, the nature and quality of advice received is a key factor in assessing fairness.
- Full disclosure of assets: were both parties open and honest about their finances? Failure to disclose material assets or debts could give the court grounds to set aside the agreement.
- Circumstances of signing: was the agreement entered into freely and voluntarily? The court will consider whether there was any pressure or unfair advantage taken by one party. Timing also matters; an agreement signed under pressure, or shortly before a wedding, may attract greater scrutiny.
General principles of contract law can also apply - such as fraud, coercion, or undue influence - to challenge a prenuptial agreement in Scotland. However, a court would be asked to look at the validity of the agreement through the lens of the 1985 Act.
What you should do with a U.S. prenup before moving to Scotland
If you have moved, or are planning to move, to Scotland with an existing U.S. prenuptial agreement, there are several practical steps you should consider to protect its terms:
- Obtain Scottish legal advice: have a Scottish family law solicitor review your existing agreement and advise you on how it is likely to be treated under Scots law, considering the “fair and reasonable” test.
- Consider a supplementary agreement: your solicitor may recommend entering into a “minute of agreement” under Scots law. This is a formal document that can reinforce or update the terms of your original prenuptial agreement in line with Scottish legal requirements. It doesn’t necessarily mean that the terms of your existing prenup change, but it does show (in the event of future challenge) that you both reconsidered the document and agreed that it still felt fair and reasonable to both of you at that point.
Whilst we always hope that prenuptial, and affirming postnuptial, agreements can be signed and then forgotten about, it is important to treat them as live documents. Agreements should be routinely checked to make sure that they still feel fair and reflective to both parties.
Why cross-border family law matters
Cross-border family law can be complex, involving questions of jurisdiction, choice of law, and differing standards for enforceability. What is adequate under U.S. state law may need to be supplemented or adjusted to hold up in a Scottish court Every couple’s circumstances are different and there is no substitute for advice tailored to your specific situation. If you are relocating to Scotland and have questions about your prenuptial agreement, we encourage you to contact our expert team for a confidential consultation. We can help you understand your position, protect your interests, and plan ahead with peace of mind.
