Protecting what you already own before you marry doesn’t mean you expect the relationship to end. For many couples it’s simply sensible planning, a way to bring clarity and mutual understanding to the finances before the wedding. A prenuptial agreement lets you both agree in advance how certain assets would be treated if you ever separated, so nothing is left to guesswork at the hardest possible moment.
This guide explains how prenuptial agreements work under Scottish law, what makes one legally binding, and how to give yours the best chance of standing up if it’s ever tested.

What a prenuptial agreement is
A prenuptial agreement, commonly referred to as a prenup, is a legal document signed by a couple before they marry or enter a civil partnership. It sets out how their finances and assets would be divided if the relationship ends in divorce or dissolution, rather than leaving that to be worked out later.
In Scotland, a prenup is treated as a legal contract. Its most common job is to ringfence certain assets, for example property, savings, a business, or an inheritance you’re bringing into the marriage, so they don’t automatically fall into the pot to be shared. It can also record how assets built up during the marriage would be divided, and set out arrangements for financial support after separation.
Prenups aren’t only for the wealthy. Any couple who want to agree their financial arrangements in advance, protect a family business, safeguard pre-marital savings, or provide for children from a previous relationship can benefit from one.
Are prenuptial agreements legally binding in Scotland?
This is where Scotland differs from England and Wales, and it matters. In England and Wales, prenuptial agreements are not automatically binding, and a court decides how much weight to give them. In Scotland, prenuptial agreements are generally treated as legally binding and enforceable contracts, provided they’ve been properly prepared.
That said, they are not automatically binding in every circumstance. Under section 16 of the Family Law (Scotland) Act 1985, a court has the power to set aside an agreement, or part of it, if it was not fair and reasonable at the time it was entered into. Scottish courts are reluctant to overturn an agreement two adults freely signed, and the fact that a prenup later produces an unequal split does not, on its own, make it unfair. But a badly drafted agreement, or one signed without proper advice, can be challenged, which is exactly why how it’s put together is so important.
What makes a prenuptial agreement valid
Scottish case law, notably the case of Gillon v Gillon, set out the principles a court applies when deciding whether to uphold such an agreement. In practice, three things give a prenup the best chance of being enforceable:
- It must be fair and reasonable at the time it was signed. Fairness is judged as at the date of signing, taking account of all the circumstances, not with the benefit of hindsight years later.
- Both parties must have independent legal advice. Each of you should have the opportunity to take separate, independent legal advice from your own solicitor before signing. This protects both of you and makes it far harder for anyone to argue later that they didn’t understand what they were agreeing to. Independent legal advice is one of the single most important factors in a court recognising an agreement.
- There must be no pressure to sign. The agreement has to be entered into freely, without coercion or undue pressure on either party.
Alongside these, full and frank financial disclosure is essential. Both of you should set out your assets, income, and debts honestly and completely. If one party hides or misrepresents assets, that can be enough to have the agreement set aside, so getting disclosure right protects the whole document.
What a prenup can and can’t cover
A prenuptial agreement is flexible, and what goes in is largely up to you as a couple. It can deal with:
- How pre-marital assets, savings, and property are treated, including the family home
- Protection of a business or professional practice
- Inheritances and gifts from family
- How assets acquired during the marriage would be divided
- Pensions accrued during the marriage
- Financial provision or support after separation
- More unusual matters, right down to who keeps the family dog
There are limits. A prenup cannot remove or reduce child maintenance obligations, and it cannot override the principle that a child’s welfare comes first. It must also comply with Scottish matrimonial property law under the 1985 Act. Some couples include a review clause, so the agreement is revisited after a significant life event such as the birth of a child, which helps keep it fair as circumstances change.
Prenuptial vs postnuptial agreements
These two are easy to confuse. A prenuptial agreement is signed before you marry. A postnuptial agreement, also called a post nuptial agreement, does the same job but is signed after the wedding.
The difference is timing, not effect. A postnuptial agreement is equally valid in Scotland and is assessed against the same fairness principles. If your wedding is close and there isn’t time to conclude a prenup comfortably, a postnuptial agreement is often the sensible route, and you can still put clear financial arrangements in place once you’re married.
When to start the conversation
There is no fixed statutory deadline in Scotland by which a prenuptial agreement must be signed. Unlike some other jurisdictions, Scots law sets no minimum period before the wedding. What matters is that there was enough time for both parties to take advice and reflect, without feeling rushed.
In practice, the more time you allow, the stronger the agreement. An agreement pushed under someone’s nose days before the wedding leaves little room for advice or genuine consideration, and that is precisely the sort of thing that opens the door to a later challenge. As a guide, starting the conversation two to three months ahead, and ideally earlier, gives you both space to negotiate, take independent legal advice, and sign well before the day. If time runs short, a postnuptial agreement remains a strong option.
Raising the subject early also tends to make the conversation easier. Talking openly about money before marriage can strengthen a relationship rather than strain it, giving you both clarity and reassurance about the future.
