A post-nuptial agreement does the same job as a prenup, but is entered into after the marriage has taken place. Couples use them when circumstances change: an inheritance, a business, a house bought with one party’s money, or a reconciliation after a period of difficulty. The legal test is the same, and so are the requirements for making one that will stand up.

What Are Post-nuptial Agreements in Scotland?
A post-nuptial agreement (post-nup) is a legal contract entered into after marriage that sets out how assets, debts, and financial responsibilities will be divided if the marriage ends in divorce or separation. Post-nuptial agreements in Scotland, like pre-nuptial agreements, carry significant weight in court proceedings when properly drafted and executed with full financial disclosure.
Scottish courts will consider post-nuptial agreements as part of their decision-making process, particularly where both parties received independent legal advice, made full financial disclosure, and the agreement was entered into freely without undue pressure. The Family Law (Scotland) Act 1985 provides the framework within which these agreements operate, treating them similarly to pre-nuptial agreements.
Post-nuptial agreements often arise from changed circumstances during marriage – a business venture’s success, inheritance receipt, career changes, or even relationship difficulties that couples wish to work through with financial clarity. They provide the same protections as pre-nuptial agreements but address the realities of married life.

Why Consider Post-nuptial Agreements in Scotland?
Post-nuptial agreements serve crucial purposes when circumstances change during marriage. They provide clarity about financial arrangements that may not have been anticipated before marriage, protect newly acquired assets, and can help couples work through financial disagreements constructively.
Many couples find that creating a post-nuptial agreement strengthens their marriage by addressing financial concerns openly. This is particularly valuable when one spouse starts a business, receives an inheritance, or when couples want to restructure their finances after years of marriage.

Requirements for Valid Post-nuptial Agreements in Scotland
Post-nuptial agreements in Scotland must meet stringent requirements to carry weight in court. Because they’re created during marriage, courts scrutinise them carefully to ensure both parties benefit and neither is disadvantaged.
Mutual Benefit
Post-nuptial agreements must demonstrate clear benefit to both parties. Courts examine whether each spouse gains something valuable from the arrangement.
• Financial security for both
• Clear asset division
• Reduced future conflict
• Protected inheritances
Legal Consideration
Unlike pre-nuptial agreements, post-nuptial agreements require clear consideration – something of value exchanged between parties beyond the marriage itself.
• Waiving claims to assets
• Financial provisions
• Support agreements
• Property transfers
Complete Disclosure
Full financial disclosure remains mandatory, with courts expecting even greater transparency given the parties’ knowledge of each other’s circumstances.
• Current valuations
• All marital assets
• Recent acquisitions
• Changed circumstances
Independent Advice
Separate legal representation for each party is absolutely essential. Courts view this as critical evidence that both parties understood the agreement’s implications.
• Different solicitors
• Documented advice
• Clear explanations
• Written confirmations

Common Triggers for Post-nuptial Agreements
Life changes during marriage often necessitate financial restructuring. Understanding common triggers helps couples recognise when a post-nuptial agreement might benefit their relationship and financial security.

When a business started during marriage becomes valuable
Property Inheritance
Receiving family property or significant inheritance
Family Planning
After children arrive and priorities shift
Reconciliation
Working through difficulties with financial clarity

Common Questions About Post-nuptial Agreements
Are post-nuptial agreements binding in Scotland?
They are not automatically binding, but Scots law gives them real weight. Under section 16 of the Family Law (Scotland) Act 1985 the court may set aside or vary an agreement only where it was not fair and reasonable at the time it was entered into. A properly prepared agreement is usually upheld.
What does a post-nuptial agreement cost?
It depends on the complexity of your circumstances, your assets and how much needs to be negotiated. We bill on a time basis in three-minute units rather than the six-minute units many firms use, and we will give you a clear estimate at the outset and revise it as matters develop.
Do we both need separate solicitors?
Yes, in practice. We can act for one of you only, and independent advice on both sides is the strongest protection against the agreement being challenged later.
Are postnuptial agreements legally binding in Scotland?
Postnuptial agreements are recognised in Scotland and the courts will generally give effect to them, but they are not automatically binding. Under section 16 of the Family Law (Scotland) Act 1985 a court can set aside or vary an agreement on financial provision if it was not fair and reasonable at the time it was entered into. An agreement entered into freely, with full financial disclosure and independent legal advice on both sides, is far more likely to be upheld.
How much does a postnuptial agreement cost in Scotland?
The cost depends on the complexity of your circumstances and the assets involved, so postnuptial agreements are charged at our hourly rates rather than a single fixed fee. We bill in three-minute units and offer a free fifteen-minute initial telephone consultation to discuss your situation and give an indication of likely cost.
What is the difference between a prenuptial and a postnuptial agreement?
A postnuptial agreement is made once a couple are already married, whereas a prenuptial agreement is entered into before the marriage. Both are treated in broadly the same way by the Scottish courts, and a postnuptial agreement is often put in place after a change in circumstances such as an inheritance or a new business interest.
What can a postnuptial agreement cover?
It can set out how assets owned before the marriage — property, savings, business interests, inheritances and gifts — are treated if the relationship ends, and how matrimonial property acquired during the marriage is divided. It cannot fix arrangements for children, which are always decided by reference to the child’s best interests at the time.
When should we consider a postnuptial agreement?
A postnuptial agreement is worth considering after a significant change in circumstances — an inheritance, a business growing in value, buying property, or rebuilding security after a difficult period. As with any such agreement, it is most robust where both parties give full disclosure and each takes independent legal advice, entered into freely and in writing.
