Pre-nuptial Agreements Beyond Divorce: A New Role in Wealth and Succession Planning?

Pre-nuptial agreements are often associated with divorce. However, for many families, they raise a broader question: how should inherited wealth, family businesses and other significant assets be protected when a couple marries?

Under the current law in England and Wales, pre-nuptial agreements can carry significant weight, but they are not automatically binding. The Government’s recent consultation on introducing legally binding “qualifying nuptial agreements” could therefore be important not only for separating couples, but also for families undertaking longer-term succession planning.

The Current Legal Position:

When deciding financial arrangements on divorce, the court has a wide discretion. This means the court looks at the circumstances of the family as a whole, including each person’s needs, income, housing position, resources and the welfare of any children, rather than simply applying the terms of a pre-nuptial agreement automatically.

The Supreme Court’s decision in Radmacher v Granatino marked an important shift. It confirmed that the court should generally give effect to a nuptial agreement where both parties entered into it freely, understood what they were agreeing to, and had the information needed to make a decision. However, the agreement will not be followed if doing so would lead to an unfair outcome.

This is why uncertainty remains under the current law. A couple may have taken adequate steps to record what should happen to inherited assets, family business interests or pre-marital wealth, but neither party can be completely certain that the agreement will be applied in full if the marriage later breaks down. For families trying to plan ahead, that lack of certainty can make it harder to decide when and how assets should be passed on.

The Proposed Reform:

The Government’s June 2026 consultation, A Fairer End to Relationships, proposes the introduction of “qualifying nuptial agreements”. These would allow couples to make binding financial arrangements in advance of a divorce or dissolution, provided certain safeguards are met.

Under the proposed framework, a qualifying nuptial agreement would be legally binding if it met the required safeguards. In practical terms, this means couples could decide in advance how certain assets should be treated if the marriage later ended, rather than leaving the issue to be determined entirely at that point. The court would still retain important protections, including the ability to ensure that financial needs are met and that any children are properly provided for.

Building on earlier Law Commission recommendations, a qualifying agreement would need to satisfy several requirements, including:

• being entered into freely, without undue influence or misrepresentation;
• being executed as a deed;
• being signed at least 28 days before the ceremony;
• both parties providing material financial disclosure; and
• each party receiving independent legal advice.

In short, the reforms would not make every pre-nuptial agreement absolute. Instead, they aim to balance personal autonomy with fairness and safeguards.

Why This Matters for Family Wealth:

The significance of the proposed reforms extends beyond divorce.

For families with trusts, business interests or inherited assets, marriage often forms part of a much wider succession planning strategy. Pre-nuptial agreements are already used to protect family assets, however their effect cannot be guaranteed because the court retains discretion to depart from them where fairness requires it. Whilst the Law Commission’s proposal similarly cannot guarantee that every pre-nuptial agreement will be upheld, it does provide greater certainty by setting out the requirements couples are required to satisfy in order to make a qualifying pre-nuptial agreement. Consequently, families would be better placed to identify, in advance, how inherited wealth, family business interests and significant gifts are to be treated if a relationship later breaks down.

This is particularly important where wealth is intended to pass down through generations. For example, parents may want to give their children money to buy a home, or a family business may be preparing for the next generation to take over. A binding agreement could make clear that those assets are intended to remain family assets, rather than becoming matrimonial and subject to a wider dispute on divorce. This can further reduce the risk of expensive litigation and provide families with more confidence when making long-term plans.

Additionally, the procedural safeguards may assist with the planning process by encouraging transparency and informed decision-making. Whilst many pre-nuptial agreements already follow these steps, mandated financial disclosure and independent legal advice help ensure that both parties understand the agreement and its implications.

Implications for Succession Planning:

Succession planning is not just about what happens on death. It can also involve gradually transferring responsibility for a family business, making gifts to children, or placing assets into trust for future generations. The reforms may be especially useful for succession planning as they may provide more certainty when passing assets on during a person’s lifetime to the next generation.

At the moment, families may hesitate before passing assets down during their lifetime because of the risk that assets transferred to the next generation could later be drawn into divorce proceedings. A qualifying nuptial agreement may help manage that risk in a better way by holding parties to the terms of any pre-nuptial agreement. This could make succession planning more practical and less reactive. Rather than waiting until a later stage, families may feel able to put plans in place at the right time.

However, a nuptial agreement should not be viewed in isolation. Effective wealth protection may also involve trusts, wills and wider estate planning. The agreement should sit within that broader framework, rather than operate as a standalone solution.

For many, the benefit is therefore not simply asset protection. It is the ability to plan with a clearer understanding of the likely outcome if a marriage breaks down. Clearer rules may reduce disputes, help couples have clear conversations before marriage, and allow families to make sensible decisions about passing wealth on without leaving everything to uncertainty later.

Looking ahead:

The consultation closed on 14 August 2026 and the proposals may change before any legislation is introduced. Nevertheless, the direction of travel suggests greater willingness to give couples more control over how their financial affairs are addressed if a relationship breaks down.

For families engaged in succession planning, the reforms may offer greater certainty. However, arrangements should be reviewed as circumstances change.

The proposals may broaden the role of pre-nuptial agreements beyond divorce planning, positioning them as a more significant part of long-term wealth and succession planning.
