When a Prenup Gives More Than “Needs”: A Quiet but Important Shift – A v Z [2026] EWHC 654

The recent decision in A v Z [2026] EWHC 654 (Fam) offers a fascinating addition to the modern law on prenuptial agreements. At first glance, it appears orthodox: the court upheld a prenup. But look more closely, and it reveals something more nuanced—and potentially significant—about how far the courts are now willing to go.

The orthodox starting point: Radmacher v Granatino

Since Radmacher, the legal framework has been clear: A nuptial agreement freely entered into with full appreciation should be upheld unless it would be unfair to do so.

In practice, this has usually meant one thing: prenups are upheld, but subject to needs.

That principle was reinforced in cases like Brack v Brack, where the Court of Appeal made clear that—even with a valid prenup—the economically weaker party will ordinarily receive provision sufficient to meet their needs, but not a sharing award.

So far, so predictable.

What makes A v Z different?

In A v Z, the husband stood to receive:

A substantial housing fund
An income fund
Half the matrimonial home
And—critically—millions of pounds for shares in the wife’s family business

Those shares were:

Non-matrimonial in origin
Gifted during the marriage
Caught by the prenup as “separate property”

Yet the court still required payment for their transfer as part of achieving a clean break.

The result? The husband emerged with far more than a strict “needs-based” outcome.

Why did the court allow this?

Mr Justice Trowell’s reasoning is subtle but important.

The prenup was upheld—but not mechanistically applied

The agreement said each party should retain their separate property.

But the court recognised a practical problem:

The parties could not realistically remain shareholders in each other’s businesses post-divorce
A clean break required transfers of those assets

Once that step was taken, the court held it would be unfair not to compensate for the transfer.

In other words: the court adapted the mechanics of the prenup to achieve fairness—without abandoning it

No “needs cap” where fairness points higher

The wife argued strongly:

The husband’s needs were already met
The shares were non-matrimonial
Therefore no further payment should be made

The court rejected that rigid approach.

Instead, it emphasised:

Fairness is the ultimate objective
Needs are important—but not an absolute ceiling

This reflects a more flexible reading of Radmacher than is sometimes assumed.

No side agreement to neutralise the shares

A key factual dispute was whether the husband had agreed the shares were:

“an empty box” (i.e. valueless on divorce)

The court found no such agreement.

That finding was decisive:

The shares were legally his
They had value
And fairness required that value to be recognised

Where does this sit in the “pantheon” of prenup cases?

This case does not overthrow the established hierarchy—but it refines it in an important way.

Stage 1: Recognition – Radmacher v Granatino

Prenups are not automatically binding, but will usually be upheld.

Stage 2: Consolidation – Brack v Brack

Fairness typically limits awards to needs where a valid prenup excludes sharing.

Stage 3: Boundary-setting – Standish v Standish

Clearer delineation between matrimonial and non-matrimonial property.

Stage 4: Flexibility in application – A v Z [2026]

The court:

Upholds the prenup
Recognises non-matrimonial property
But still allows an outcome exceeding strict needs where fairness requires it

Why this case matters in practice

This decision highlights three key points for practitioners:

Prenups are not rigid instruments

Even a well-drafted agreement may be adapted in its operation to achieve fairness.

“Needs only” is not always the end point

Where assets are transferred (especially for clean break purposes), compensation may take the outcome beyond needs

Structure matters as much as wording

Here, the absence of:

A clear buy-out mechanism
A provision addressing inter-spousal share transfers

created the space for the court’s intervention.

A quiet evolution—not a revolution

A v Z does not weaken prenups. If anything, it reinforces their importance. But it does send a clear message:

Fairness remains the lodestar—and fairness is fact-sensitive, not formulaic.

For family lawyers, the case is a reminder that the real question is not:

“Is there a prenup?”

but:

“How will the court apply it in the real-world context of this marriage?”

False Prenups, Hidden Assets and an Art Collection: Lessons from a Complex Divorce Case

Financial remedy cases often involve difficult factual disputes, but KMR v AER is a particularly striking example. The judgment touches on several recurring themes in modern family litigation: the validity of nuptial agreements, non-disclosure of assets, economic misconduct, and how the court deals with attempts to dissipate wealth.

It is a reminder that in financial remedy proceedings, credibility and transparency can ultimately determine the outcome.

A Disputed Prenuptial Agreement

One of the central issues was whether the parties had entered into a valid nuptial agreement. The husband asserted that an agreement had been signed in Switzerland shortly before the marriage and should limit the wife’s financial claims.

The court approached the issue using the principles set out in Radmacher v Granatino, which established that a nuptial agreement may carry decisive weight if freely entered into with full understanding and without unfairness.

But the evidence unravelled quickly.

Documents contained inconsistencies, translation discrepancies and missing formalities. The husband could not explain the absence of the notary’s seal, the differences between versions of the agreement, or even precisely when or where it had been signed. Ultimately, the judge concluded that the purported agreement was not merely invalid but effectively a fabrication intended to mislead the court.

As a result, it had no impact on the financial distribution.

The Court’s Struggle to Identify the True Asset Picture

Another striking feature of the case was the difficulty in determining the real value of the parties’ wealth.

The husband had interests in several companies and an extensive art collection. However, valuations were inconsistent, documentation incomplete, and disclosure frequently inadequate. The judge noted repeated failures to comply with court directions and a lack of credible evidence supporting the husband’s figures.

Faced with this uncertainty, the court adopted the familiar approach of making a “ballpark” assessment of the marital assets, estimating them at around £6.84 million.

Where the lack of clarity was caused by one party’s non-disclosure, the court was entitled to draw adverse inferences.

Dissipation of Assets and Economic Misconduct

The judgment also addresses economic misconduct, referencing the framework described by Mostyn J in OG v AG.

The judge found that the husband had engaged in conduct designed to obscure or dissipate assets, including transactions and financial arrangements that made the true ownership of assets difficult to identify. Such behaviour, if sufficiently serious, can justify adjusting the financial outcome.

In this case, the court concluded that the husband’s conduct met the high threshold required for it to be inequitable to ignore.

The practical response was not punishment but financial adjustment: assets that had been dissipated or concealed were effectively brought back into the matrimonial calculation.

Non-Matrimonial Property Still Matters

The case also illustrates the court’s approach to non-matrimonial property.

Certain assets — including a Paris apartment purchased before the marriage and property held within the wife’s family trust — were treated as non-matrimonial and excluded from the sharing exercise.

However, the court still had to consider the parties’ needs and overall fairness when dividing the marital assets.

The Final Outcome

The court made significant capital orders in the wife’s favour, including:

Transfer of the husband’s art collection to the wife so it could be realised to fund her housing needs.
A lump sum payment of £1 million.
Additional contingent payments linked to ongoing litigation involving one of the husband’s companies.

The structure of the order reflected the judge’s lack of confidence that the husband would voluntarily comply without robust mechanisms.

What This Case Tells Us

KMR v AER highlights several important realities of financial remedy litigation:

Prenuptial agreements must be properly executed.
Poorly drafted or suspicious documents will carry little or no weight.
Full and frank disclosure remains the cornerstone of financial proceedings.
Attempts to obscure assets frequently backfire.
Conduct can still matter.
While the threshold is high, economic misconduct or asset dissipation can influence the outcome.
The court will take a pragmatic approach.
Where precise figures cannot be established due to one party’s conduct, judges will still reach a fair estimate.

Final Thoughts

Family finance cases often turn less on legal argument than on credibility, disclosure and evidence. When parties attempt to manipulate the financial picture — whether through dubious agreements, opaque asset structures or incomplete disclosure — the court is well equipped to respond.

KMR v AER is a vivid illustration that transparency is not just good practice in financial remedy proceedings — it is essential.

When Conduct Undermines a Prenup: Lessons from Loh v Loh Gronager [2025] EWFC 483

Pre‑nuptial agreements are often presented as the ultimate form of certainty in financial remedy proceedings. Properly drafted, independently advised, and entered into freely, they are intended to provide clarity, limit dispute, and avoid costly litigation. But Loh v Loh‑Gronager is a powerful reminder that even the strongest prenup is not a licence to behave badly — and that conduct can still play a decisive role where fairness is put at risk.

The background

The parties entered into a detailed and sophisticated pre‑nuptial agreement which the court accepted was fully compliant with the principles in Radmacher v Granatino. The agreement disapplied sharing and compensation and limited the husband’s entitlement by reference to the length of the marriage. On its face, that would have produced an award of around £6.4 million.

However, the husband’s ultimate award was reduced to approximately £2.3 million. The reason lay not in needs, nor in any technical defect in the agreement, but in his conduct — both during the marriage and in the litigation itself.

Prenups do not authorise self‑help

One of the most striking features of the judgment is the court’s rejection of the husband’s apparent belief that the prenup entitled him to treat joint funds as his own. Cusworth J was clear that joint accounts and jointly held monies have a defined purpose, and unilateral withdrawals for personal use — even where one party asserts tacit approval or lack of objection — are not justified.

The court was unimpressed by arguments that the wife could have monitored the accounts more closely or that silence amounted to consent. A prenup may regulate what happens on divorce, but it does not rewrite the basic principles governing joint property during the marriage.

When conduct crosses the threshold

Conduct arguments in financial remedy cases rarely succeed, and the bar remains high. This case illustrates precisely what is required to meet the statutory test of conduct that would be “inequitable to disregard” under section 25(2)(g) of the Matrimonial Causes Act 1973.

Cusworth J found that the husband’s behaviour went well beyond ordinary marital or litigation friction. It included:

repeated misuse of joint and ring‑fenced funds;
secretive financial dealings;
intimidation and harassment;
and, most seriously, the fabrication and manipulation of documentary evidence.

This was not conduct being punished for its own sake. The judge carefully linked it to fairness, credibility, and the integrity of the proceedings, concluding that it would be unjust to allow the husband to receive the full benefit of the prenup in those circumstances.

Fabricated evidence: a line rarely crossed

Findings of fabricated evidence are unusual and profoundly damaging. Cusworth J described this as among the most serious forms of litigation misconduct encountered in the Family Court. Once such findings were made, the husband’s credibility was fatally undermined and his case infected throughout.

The judgment is a stark warning that attempts to manufacture or doctor evidence are likely to backfire catastrophically, affecting not just costs but the substantive outcome itself.

Fairness under Radmacher

Importantly, the court did not treat conduct and the enforceability of the prenup as separate exercises. Instead, Cusworth J analysed whether it would be fair to hold the parties to the agreement in light of the husband’s behaviour. In doing so, he effectively aligned the Radmacher fairness test with the statutory conduct principles, demonstrating how the two operate together rather than in isolation.

Costs and proportionality

The case also stands as a sobering illustration of litigation excess. The parties incurred almost £4.8 million in legal costs to determine an entitlement ultimately fixed at £2.3 million. The judge observed that something had “gone very wrong”, highlighting the destructive potential of entrenched positions and aggressive litigation strategies.

Why this case matters

Loh v Loh‑Gronager is not simply a high‑net‑worth cautionary tale. It reinforces several key principles:

prenups do not excuse financial misconduct;
conduct can still materially affect outcome in truly exceptional cases;
dishonesty in proceedings is likely to be met with severe consequences; and
litigation strategy can be just as important as legal entitlement.

For clients and practitioners alike, the message is clear: certainty only works when matched with integrity. A prenup may set the framework, but fairness — and behaviour — still matter.

Pre-Nuptial Agreements: Validity and Needs – Insights from HW v WB [2024] EWFC 328

The case of HW v WB [2024] EWFC 328 sheds light on the role of pre-nuptial agreements (PNAs) in financial remedy proceedings and the court’s approach to balancing agreements with the needs of the parties. District Judge Phillips upheld the validity of the PNA but adjusted its terms to ensure fairness, especially in light of the wife’s ongoing financial needs and her role as the primary carer for the couple’s child.

Background

The parties, who had been married for nine years, entered into a PNA shortly after their wedding. The husband, 65, had accumulated significant pre-marital wealth, including a mortgage-free family home, substantial pensions, and savings. The wife, 41, brought limited assets and gave up employment to focus on childcare during the marriage. After separation, the wife argued that the PNA failed to meet her needs, especially as it made no provision for maintenance beyond housing.

The Court’s Approach

Validity of the Agreement:
The court found the PNA valid and binding. The wife had received independent legal advice and signed the agreement freely, acknowledging its implications. While she felt some pressure due to her immigration status and pregnancy, this did not constitute undue pressure negating the agreement.
Needs-Based Adjustments:
Despite upholding the agreement’s validity, the court emphasised the need to address the wife’s financial circumstances. The PNA’s terms, which focused solely on capital provision for housing, were deemed inadequate for meeting her ongoing needs as the primary caregiver for the couple’s 10-year-old son.
Fair Distribution:
The court awarded the wife £489,000, including a lump sum for housing and additional capitalised maintenance for four years, enabling her to retrain and gain financial independence. It also included a pension sharing order to equalise retirement income.

Key Legal Points

Binding Nature of PNAs:
Pre-nuptial agreements are upheld unless there are vitiating factors such as duress or fraud. However, they must be fair in light of the section 25 factors under the Matrimonial Causes Act 1973, particularly where children are involved.
The Court’s Discretion:
Even when a PNA is valid, the court retains discretion to adjust its terms to meet the reasonable needs of the parties, ensuring a fair outcome.
Weight of Needs:
The wife’s role as the primary carer and the inadequacy of the PNA in providing for her needs justified a departure from its strict terms.

Implications for Practitioners

This case underscores the importance of drafting PNAs with clear provisions for potential future needs, especially where children are anticipated. While PNAs offer valuable certainty, they must be balanced against evolving circumstances to avoid being deemed unfair.

For family lawyers, HW v WB illustrates how courts navigate the interplay between upholding agreements and ensuring fairness, offering a nuanced approach to financial remedy disputes.

Prenuptial Agreements and Parental Loans in Divorce

Key Takeaways from ND v KD [2024] EWFC 188 (B)

Divorce proceedings often unravel intricate personal and financial histories, making each case unique. The recent judgment in ND v KD [2024] EWFC 188 (B) offers valuable insights into the legal handling of prenuptial agreements and parental loans. Here's what you need to know:

Prenuptial Agreements Under Scrutiny

In ND v KD, the prenuptial agreement (PNA) was a central issue. The court found the agreement to be invalid due to undue pressure exerted by the husband. Despite initial financial disclosures and legal advice received by the wife, the agreement was signed under significant emotional and logistical stress just days before the wedding. This case underscores the importance of ensuring that both parties enter into such agreements voluntarily and with a clear understanding of their implications.

Key Takeaway: For a prenuptial agreement to hold up in court, it must be entered into freely, without coercion, and must be fair to both parties.

Classifying Parental Loans

Another critical aspect of this case was the classification of parental loans. The husband received substantial financial support from his father, framed as loans for property development. The court determined these to be "soft loans," implying flexible repayment terms contingent on future financial success. Conversely, the wife's loans from her parents were more formally structured but also considered with an understanding of familial flexibility.

Key Takeaway: The nature of financial support from family members can significantly impact divorce settlements. Clear, formal agreements can help, but the court will also consider the realistic expectations of repayment and the overall context.

Ensuring Fair Settlements

The court's decision aimed to provide a fair outcome for the wife and child, considering the invalid PNA and the nature of the loans. The husband was ordered to provide substantial financial support, reflecting the court's commitment to equity and the well-being of the child involved.

Key Takeaway: Divorce settlements strive to balance fairness with practical considerations of need and future stability, especially when children are involved.

Final Thoughts

The ND v KD case is a reminder of the complexities involved in divorce proceedings and the meticulous attention courts pay to the fairness and voluntariness of agreements. For individuals considering or currently navigating a divorce, this case highlights the importance of transparent, fair agreements and the potential impact of family financial dynamics on settlements.

Prenuptial Agreements: Protecting Your Assets and Future

Prenuptial agreements, often referred to as prenups, are legal documents designed to protect the assets and interests of individuals entering into marriage. While some may view prenups as unromantic or pessimistic, they serve a practical purpose in safeguarding both parties in the event of divorce or death. Here’s why prenuptial agreements are important and why couples should consider them before tying the knot:

Asset Protection: One of the primary purposes of a prenuptial agreement is to outline the division of assets in the event of divorce. By clearly defining each spouse’s property rights and financial responsibilities, a prenup can prevent disputes and litigation over property division during divorce proceedings.
Debt Allocation: In addition to assets, prenuptial agreements can address how debts acquired during the marriage will be handled in the event of divorce. This can include mortgages, student loans, credit card debt, and other financial liabilities.
Clarity and Certainty: Prenuptial agreements provide clarity and certainty about financial matters, which can reduce conflict and uncertainty in the event of divorce or separation. By establishing clear guidelines for asset division and financial support, couples can minimise the risk of contentious legal battles down the road.
Protection of Business Interests: For individuals who own businesses or have significant investments, a prenuptial agreement can help protect those assets from being divided in the event of divorce. Without a prenup, a spouse may be entitled to a share of the business or its profits, which can have serious implications for its future viability.
Estate Planning: Prenuptial agreements can also address issues related to estate planning and inheritance. This can include provisions for spousal support, distribution of assets upon death, and protection of inheritances for children from previous relationships.
Tailored to Your Needs: Prenuptial agreements are customisable legal documents that can be tailored to meet the specific needs and circumstances of each couple. Whether you have complex financial portfolios, children from previous marriages, or unique family dynamics, a prenup can be crafted to address your individual concerns and objectives.
Open Communication: Discussing and drafting a prenuptial agreement requires open and honest communication between partners. While it may not be the most romantic conversation, it can lead to a deeper understanding of each other’s financial goals, values, and expectations.

In conclusion, prenuptial agreements offer couples a proactive and practical way to protect their assets, clarify financial expectations, and plan for the future. By addressing these important issues before marriage, couples can lay the groundwork for a stronger and more secure relationship built on trust and mutual respect.
