A prenuptial agreement, or prenup, is a document that sets out how a couple’s assets, income and financial responsibilities should be arranged if they ever decide to separate. It is usually prepared before a marriage or civil partnership (although post-nuptial agreements also exist) and, while it is not legally binding, it can carry significant weight when determining financial settlements in divorce proceedings.
As such, a prenuptial agreement can be a practical approach to financial planning for many people, in advance of changes in your financial situation that will arise once you get married. It demonstrates the intentions of each party at the time of their marriage, and can distinguish between pre-marital assets, jointly acquired assets and inheritance or family wealth in a way that is persuasive to the court, provided key legal requirements are met.
While prenuptial agreements are often viewed as only having value to very high net-worth individuals, there are practical benefits for many people. Drafting a prenup allows you to consider your financial position and determine, alongside your partner, how your financial affairs should be managed during the relationship. It does not indicate that either party expects the relationship to end, only that you wish to be prepared for this unlikely outcome. The breakdown of a relationship can be complex in both practical and emotional ways, and having an agreement already in place offers clarity and confidence that can help you to move forward.

What is a prenuptial agreement for?
The family court in England and Wales determines financial settlements following divorce on a discretionary basis, with reference to a checklist of factors including the needs of the parties, and the needs of any children. No matter how assets were brought into the relationship, they may be considered marital assets or divided for the purposes of a fair financial settlement. The court’s aim is to make financial settlements that are fair and equitable, and which help both parties to maintain the lifestyles they enjoyed during the marriage where possible.
For high net-worth individuals who bring significant assets to a relationship, this can result in serious losses. Even for homeowners or others with a small portfolio of assets, a settlement can unbalance your financial position. This is the value of a prenup – while it is not legally binding, the court can use it to identify what the relevant parties determined about their finances before they married, and reach a decision based on this shared understanding.
Who can benefit most from a prenup?
Prenuptial agreements have obvious advantages for high net-worth individuals, but a range of people may benefit from having such a document in place before they get married. If you are already married, it is also possible to secure a post-nuptial agreement with the same purpose. Provided it was freely entered into by both parties, it will be considered with equal weight by the court.
Those who should consider seeking a nuptial agreement before or after they get married or enter a civil partnership include:
- Anyone with personal or family wealth, assets or investments
- Those with significantly more assets or a larger income than their partner
- Anyone whose partner has debts or liabilities
- People who are due to receive an inheritance in the future
- Those who are marrying for a second time and have pre-existing family commitments
- People who own businesses or have interests in a privately held company
The value of a prenup in each case is determined by the specifics, but the document itself can contain provisions covering all of the above scenarios. In fact, nuptial agreements can be very flexible, and the details may be bespoke to a couple’s particular circumstances.
For example, a prenuptial agreement may contain provisions for:
- Assets such as property, savings or investments that were acquired before the marriage
- How inheritance, trusts or family wealth should be handled
- Shares in a company, partnership arrangements or other business interests
- What will happen to family assets that are intended to remain within the family
- How future assets and income will be treated during the marriage
- Intentions for the division of property or financial responsibilities in the event of separation
Provided the agreement is fair and shows that both parties understood and approved of its contents when it was signed, it is likely to be given serious consideration by the court in determining a financial settlement. However, there are key legal tests that the document must meet before it can be used in this way, and documents that have not been prepared by an experienced prenuptial agreement lawyer may be overturned by the court.
What gives a prenup legal weight?
A Supreme Court decision in 2010 indicated that the court would consider a prenup when determining a fair financial settlement in divorce proceedings or the dissolution of a civil partnership. Certain legal standards should be met to make your document as likely as possible to be considered by the court, and failure to meet the below requirements could see the document overturned.
- Both parties must have sought independent legal advice before signing the document
- Both partners must provide full financial disclosure of all their relevant assets, income and liabilities
- The agreement must have been freely entered into – often meaning that it was signed long before the wedding, as agreements signed on the eve of marriage may have been subject to pressure
With these requirements met, the court will take the document into account when preparing a financial settlement as long as it believes that the terms are fair to both parties, and that their needs will be met. While the court has discretion to make the ultimate decision, a prenup can have a strong influence on that decision in the right circumstances.
How to arrange a prenup
If you believe a prenup is right for you, start the process as early as possible. Beginning with an informal discussion allows both partners to prepare full financial disclosure and think about what they need from the document. From there, both parties should contact an experienced solicitor to draft the agreement on their behalf. Independent legal advice is a key part of ensuring that the prenup is fair.
The solicitors can manage the financial disclosure and negotiate terms to protect both parties’ interests. With the agreement finalised, you can proceed with your marriage or civil partnership with the confidence that your financial position is protected and that you and your partner have a shared understanding of how things would be handled in the event of a divorce or dissolution.
