The issue of dividing assets upon divorce can be fraught with complexity, especially where substantial wealth or inherited property is concerned. While some assets are straightforwardly matrimonial—those built up jointly during the marriage—others sit in a grey area. These may include property owned prior to the marriage, inherited wealth, or gifts received individually. The legal concept of ring-fencing non-matrimonial assets aims to protect such assets from being included in the financial settlement upon divorce.
The issue of dividing assets upon divorce can be fraught with complexity, especially where substantial wealth or inherited property is concerned. While some assets are straightforwardly matrimonial—those built up jointly during the marriage—others sit in a grey area. These may include property owned prior to the marriage, inherited wealth, or gifts received individually. The legal concept of ring-fencing non-matrimonial assets aims to protect such assets from being included in the financial settlement upon divorce.
But how effective is this approach in practice? Does it genuinely protect personal wealth, or do courts frequently override it in pursuit of fairness?
A high-profile case currently before the UK Supreme Court, Standish v Standish, could provide critical clarification on how non-matrimonial assets are to be treated, and whether they should always be considered part of the marital “pot.” This article explores the legal framework, practical implications, and key case law surrounding the issue, with a focus on how ring-fencing non-matrimonial assets can work—or fail—in modern divorce proceedings.
What are non-matrimonial assets?
In English family law, assets are broadly divided into two categories: matrimonial and non-matrimonial. Matrimonial assets are typically those acquired during the course of the marriage, through the efforts of either or both spouses. These are subject to the principle of equal sharing established in landmark cases like White [2000] and Miller and MacFarlane [2006].
In contrast, non-matrimonial assets are those not directly derived from the joint endeavour of the marriage. These often include:
-
Pre-marital assets, i.e. those acquired before the marriage
-
Assets received by gift or inheritance during the marriage
-
Wealth or property kept separate from joint family life
However, this distinction is not always clear-cut. If pre-marital assets are mingled with matrimonial finances—such as being placed in joint names or used to purchase a matrimonial home—it may lose its non-matrimonial character. This is where the concept of ring-fencing non-matrimonial assets becomes relevant.
What does ring-fencing mean?
Ring-fencing non-matrimonial assets involves identifying and segregating assets that should not be shared upon divorce. This is typically done on the basis that these assets fall outside the economic partnership of the marriage and therefore should remain with the individual who brought them in or received them.
The rationale is that it would be unfair to divide assets one party had before the marriage, particularly in shorter marriages or where there are no children involved. However, the court maintains a wide discretion and may override ring-fencing arguments if fairness demands it.
Standish v Standish: A case that could shift the landscape
The ongoing case of Standish v Standish brings the issue of ring-fencing non-matrimonial assets sharply into focus. The case involves Clive Standish, a former UBS banker, and his wife Anna. In 2017, Clive transferred approximately £80 million to Anna, purportedly as part of a tax planning arrangement that was supposed to benefit their children via a trust. The trust, however, was never set up.
When divorce proceedings commenced in 2020, the central question became whether these assets should be regarded as matrimonial property and divided, or whether they remained Clive’s pre-marital assets, and therefore subject to ring-fencing.
At first instance, the High Court ruled that the assets had become matrimonial and awarded Anna £45 million. However, on appeal, the Court of Appeal reversed that decision, siding with Clive and emphasising that the source of the wealth was the key consideration. They concluded that even though the money had been transferred during the marriage, its character as non-matrimonial had not changed.
This decision brings renewed emphasis to the origins of an asset rather than its formal transfer or use. If upheld by the Supreme Court, it could strengthen the position of those seeking to ring-fence wealth brought into a marriage, even if it was later transferred to the other spouse.
Examples of non-marital property and when they may be shared
There are several examples of non-marital property that may or may not be successfully ring-fenced:
-
Inherited wealth – If kept in a separate account and not used for joint purposes, inheritance is often excluded from division.
-
Gifts – Similar to inheritance, gifts received individually may remain non-matrimonial unless shared or used for joint benefit.
-
Pre-marital assets – A personal items, business or investment portfolio owned prior to the marriage could be ring-fenced, unless expanded using matrimonial funds.
-
Property used as a matrimonial home – Even if acquired before the marriage, a home that becomes the couple’s shared residence may lose its non-matrimonial character because of its role in family life.
The key distinction often lies in how the asset was treated during the marriage. Once a non-matrimonial asset is used to purchase the matrimonial home, for instance, courts may treat it as joint property—even if it began as a personal asset.
Matrimonial home vs matrimonial property: What’s the difference?
Understanding the difference between the matrimonial home vs matrimonial property is important. The matrimonial home is typically the family residence and is given special treatment by courts. Even if one party owned it outright prior to marriage, it is often considered a matrimonial asset due to its centrality in family life.
Matrimonial property, on the other hand, refers to all property acquired during the marriage through joint effort. This includes pensions, income, savings, and even businesses if both parties contributed—financially or otherwise.
Courts are more likely to share the matrimonial home regardless of its origin, whereas other property may be subject to ring-fencing if it clearly falls outside the scope of joint endeavour.
When ring-fencing fails
Despite best efforts, ring-fencing non-matrimonial assets are not always successful. The courts are governed by Section 25 of the Matrimonial Causes Act 1973, which requires them to consider all the circumstances of the case. The ultimate goal is fairness, and if that means breaching a ring-fence to meet the financial needs of a spouse or children, the court will not hesitate to do so.
Notable examples include:
-
Miller v Miller [2006], where even a short marriage led to significant sharing of wealth, despite arguments around non-matrimonial origin.
-
Robson v Robson [2010], where inherited wealth was brought into the marital economy and lost its ring-fenced status.
-
K v L [2011], where the court recognised non-matrimonial assets but awarded a significant share to the financially weaker spouse because of needs.
How to strengthen ring-fencing
While ring-fencing is not absolute, there are ways to strengthen its enforceability:
-
Use a prenuptial or postnuptial agreement – These documents can clearly define what assets are to be excluded from matrimonial division.
-
Keep assets separate – Do not place non-matrimonial assets in joint names or use them for joint expenses.
-
Avoid using non-matrimonial assets for family purchases – Particularly for buying or improving the matrimonial home.
While prenuptial agreements are not legally binding in England and Wales, they are increasingly upheld where fair and freely entered into with full disclosure.
Conclusion: A useful but unreliable shield?
So, does ring-fencing non-matrimonial assets help? The answer is a qualified yes.
It can be a useful tool for preserving wealth in certain circumstances, particularly when assets are kept separate and clearly identifiable as non-matrimonial. However, the discretion of the courts, and the overriding principles of fairness and need, means that ring-fencing is never guaranteed to succeed.
The upcoming Supreme Court decision in Standish v Standish will probably clarify the limits of ring-fencing, particularly in cases involving large between-spousal transfers and wealth planning strategies. For now, anyone seeking to protect pre-marital assets should act early, seek legal advice, and consider robust legal agreements to support their intentions.
