What things are considered non matrimonial assets?
It is not always straightforward to determine what assets should be considered non-matrimonial. Assets could include gifts, an inheritance or capital acquired via investments or earnings, but there is no standard definition.
Examples of non-matrimonial assets can include those:
- Inherited by one party during the marriage
- Received as a gift by one spouse to the other
- Already owned by one party before marrying
- Property acquired by one party and solely owned by them, which is not the family home
To qualify as a non-matrimonial asset, it must remain separate and distinct from matrimonial property. But ring-fencing these assets is not guaranteed. Family law is no one size fits all and works on a case by case basis for which the division starting point is 50:50. The court will only depart from this if one party has a greater need than the other or if one party can show they made a significant contribution to the matrimonial assets.
Can I stop my assets being included in the divorce?
If there are assets you believe should not be included in the divorce settlement, you can ask the court to potentially exclude it from the available assets. This could happen where:
- You received an inheritance, or are due to receive an inheritance after you separated from your spouse
- You owned property before you married, such as rental property, a share portfolio or other assets that were not merged into the matrimonial melting pot
- You held a high value pension before you were married
- You set up or owned a business before you married
Such a request is more likely to succeed if the matrimonial assets available adequately cover the needs of both of you for yourselves and any children, if you have been open and honest in your financial disclosure from the outset, or have been married for a relatively short time.
Could a pre-nuptial agreement protect my assets?
Pre-nuptial agreements are used increasingly as a way of addressing, in advance of the marriage, how assets are to be divided in the event of separation or divorce. Although they are not strictly legally binding (in certain circumstances they can be overturned by the court), they can be upheld, providing certain formalities are met and the provisions of the agreement are fair. It is also possible to enter into a post-nuptial agreement after marrying.
In most cases, pre-nuptial and post-nuptial agreements will be binding, provided they were entered into freely and not signed in unfair circumstances or under duress.
Placing non-matrimonial assets into a trust can also be an effective way to protect property. In a legal trust, a third party (trustee) is given formal control of specific assets on behalf of their owner, who is known as the beneficiary.
In summary, matrimonial assets will be shared and non-matrimonial assets will not be, however, the court has a wide discretion to do what they believe is fair, based on all the circumstances of the case. A key factor when making a decision is the extent to which the non-matrimonial property has been merged with other property and how this has been used during the marriage. Division of assets on divorce is a complex area of law; getting specialist advice early on can demystify the process and explain how your assets might be treated.
How the family courts define and treat non-matrimonial assets
When discussing non-matrimonial assets in divorce, it is important to understand why these assets are treated differently from matrimonial property and how the family courts approach them in practice.
The starting point in financial remedy proceedings under the Matrimonial Causes Act 1973 is the principle of fairness. Traditionally, courts begin by identifying all financial resources available and then work through a checklist of factors, including needs, contributions, and obligations, to reach a fair settlement.
However, the status of non-matrimonial assets introduces a nuance, and while these generally don’t count towards equal sharing, the court’s ultimate priority is fairness, not rigid categorisation. This means that non-matrimonial assets have the potential to be considered in a financial settlement in certain circumstances.
When non-matrimonial assets become shared
One of the most significant developments in family law is the way courts assess whether non-matrimonial assets have been “matrimonialised” — that is, treated so closely with shared marital finances that they lose their separate nature.
The UK Supreme Court in Standish v Standish clarified that simply transferring assets into a spouse’s name or into joint ownership does not automatically convert them into matrimonial property. Instead, the transfer must be shown to reflect a genuine intention by both spouses that the asset should be shared, such as by consistent joint use or commingling with other matrimonial assets.
This case involved a very large sum of investment funds that had been moved between spouses for tax-planning purposes. The Supreme Court confirmed that because these funds were not genuinely used as part of the couple’s shared wealth, a significant portion remained non-matrimonial, even though legally owned or managed by both parties during the marriage.
This decision is significant because it tightens the tests for matrimonialisation, meaning that someone’s ability to protect their pre-marriage wealth or gifts during divorce has become more manageable provided the right evidence is available.
The needs principle
Even where assets are clearly non-matrimonial, family courts may still consider them if:
- One spouse’s financial needs cannot be met from matrimonial assets alone
- The standard of living during the marriage suggests access to additional funds is required
- There are children whose welfare cannot be supported adequately otherwise
For instance, if a wealthy spouse inherited a significant portfolio and used it sparingly during the marriage, and the other spouse has limited earning capacity and limited matrimonial assets to support themselves post-divorce, the court may partially draw on that inheritance to meet basic needs.
This doesn’t mean automatic equal sharing; rather, it reflects the court’s discretion under the statutory fairness checklist as detailed below.
Factors that influence protection of non-matrimonial assets
The ability to protect such assets hinges on context and behaviour. Here are some practical factors that influence the court’s analysis:
- Length of marriage: Over long marriages, typically around 15–20+ years, the distinction between matrimonial and non-matrimonial wealth can blur significantly. Funds invested jointly over decades or used for the family’s benefit may be seen as part of the shared matrimonial estate.
- Contribution to the asset: If one spouse built a business before marriage but significantly expanded it during the marriage, with the other spouse’s involvement in administration or support, the increase in value may be treated as matrimonial, even if its baseline value was non-matrimonial.
- Use within the marriage: Assets kept strictly separate like those kept in individual accounts, not used for mortgages, living costs, children’s expenses or joint investments, have a stronger claim to remain outside the sharing pool.
Practical strategies to protect non-matrimonial assets
There is no magic shield against the family courts broad discretion, but there are legitimate planning steps that can help clarify intentions and make it easier to ring-fence assets:
- Prenuptial and postnuptial agreements: As set out in this article, these agreements can set expectations in advance about how assets are treated in the event of divorce. While not automatically legally binding, if structured fairly and entered into freely with full financial disclosure, they are given significant weight by the courts. A well-drafted agreement can clearly identify which assets are intended to remain non-matrimonial and how any future growth should be treated.
- Keeping accurate records: Maintaining precise documentation of:
- When the asset was acquired
- How it has (or hasn’t) been used in the marriage
- Whether it has ever been commingled with joint funds
can make a real difference in later proceedings. Financial transparency reduces disputes over classification of the asset.
- Trust arrangements: In some circumstances, placing assets in a properly structured trust before marriage can help ensure they remain separate. However, courts will examine whether such arrangements are genuine and not just intended to avoid financial obligations.
Common misunderstandings about non-matrimonial assets
There are several misconceptions that people bring into divorce negotiations:
- If it’s in my name, it’s mine: Ownership on paper is not decisive — the court looks at substance and use and whether or not the asset in question has been absorbed into the matrimonial asset pot either wholly or partly.
- Pre-marriage assets are always excluded: As established above, even pre-marriage assets may be shared if they have been used for family benefit or to meet joint needs. They may also be included if fairness cannot be achieved any other way.
- Keeping accounts separate protects them: Separate accounts help, but funds that are used to buy a family home or pay household bills may still be treated as shared in practice.
Balancing protection and fairness
As we have seen, non-matrimonial assets can often be excluded from sharing on divorce, but this is not automatic. The courts balance the origin and treatment of the assets against the need to reach a fair outcome for both spouses. Landmark decisions such as Standish v Standish demonstrate that proper classification and documentation are critical, and that simplistic tests like whose name it is in or timing alone are unlikely to be sufficient.
Ultimately, anyone concerned about protecting non-matrimonial assets should seek legal advice as soon as possible, consider formal agreements, and ensure transparent financial conduct throughout their marriage.
