How to protect inheritances, trusts, and business assets from division during divorce
When a divorce takes place in England and Wales, there is no automatic 50/50 division of everything a couple owns, a fact which surprises a great many people. Equal sharing is the usual starting point for assets built up during the marriage, but the overriding aim is a fair outcome, and the question of whether a particular asset can be divided is a matter of real complexity. The situation depends on the source of the asset, the way it was handled during the marriage, and whether the other person’s financial needs can be met without having to touch it.
It is common for those seeking advice on family law to be surprised to find out that property acquired before the marriage, money inherited from a parent, or a family business established before the relationship started does not automatically become part of the shared assets. In some cases, there is a strong case for excluding certain assets, for example, money inherited and kept in a sole account throughout the marriage. In other instances, assets that were originally separate may have lost some or all of their separate character because of the way they were used, such as inherited money that was deposited into a joint account and then spent on mortgage payments or on improving the home. This guide outlines the differences, identifies the potential risks, and gives you the practical steps you can take to secure what is truly your own.
What assets cannot be split in a divorce in the UK? Non-matrimonial assets explained
The main categories courts recognise
The concept of “non-matrimonial property” is one that has developed through the decisions of courts in England and Wales and is not a specific category laid down by statute. In practice, the courts recognise several main kinds of asset that may be treated as non-matrimonial and therefore excluded from the sharing principle:
assets owned before the marriage; inherited property or money received at any point; personal gifts from third parties intended for one spouse alone; certain personal injury compensation awards; assets acquired after separation through independent effort; some business interests or pension elements built entirely outside the marital partnership
Since there is no definitive list provided in the statute, the classification must always be based on the particular facts of the case.
Why there is no automatic protection
Just because a classification as non-matrimonial is given does not mean that it is guaranteed. According to section 25 of the Matrimonial Causes Act 1973, the court must have regard to all the circumstances of the case, giving first consideration to the welfare of any child of the family under 18, and it has a wide discretion as to how the assets are dealt with. In reality, the courts first determine which assets are matrimonial, assess their value, and then decide whether any property held separately should be used in order to achieve a fair result. If it is necessary to do so because of needs, housing, or the welfare of any children, even a property that is clearly non-matrimonial can be included in the settlement.
How courts decide whether an asset stays separate or gets shared
Source, timing and use: three practical questions
When an asset is in dispute, it helps to think about three related questions. The first of these is about its source: was the asset the result of efforts made during the marriage, or did it come from a completely separate origin, for example through inheritance or from a business owned before the marriage? The second question concerns the timing: was the asset obtained before the marriage, during the marriage, or after the couple had separated? The third is about its use: was it maintained as a personal asset, or was it incorporated into family life, joint bank accounts, or the family home? The longer the period that elapses after separation during which an asset is produced by one party’s own efforts, the stronger the case for excluding it, although there is no set time frame.
The matrimonialisation problem
An asset which at first is separate can become matrimonial property, in whole or in part, because of the way it is dealt with over time. This is known as matrimonialisation.
After the Supreme Court’s ruling in Standish v Standish [2025] UKSC 26, the key question is whether the parties, over time, treated the asset as shared. A transfer between spouses made for tax-planning purposes will not normally, by itself, matrimonialise an asset; however, where an inheritance is deposited into a joint account and then used for holidays, home improvements, or joint mortgage payments, it is different: the earlier origin of the asset becomes less and less relevant the more it is put to joint use.
When needs override everything else
In many cases, meeting each party’s reasonable needs, particularly for housing and income, is the decisive issue. Where the matrimonial assets are not sufficient to cover the housing and income needs of both parties or those of any children, the court may have recourse to non-matrimonial property, whatever its source. An inheritance held separately is a strong initial argument, not an absolute protection. It is essential to grasp this difference before you conclude that any asset is safe.
Which inherited assets cannot be split in a divorce in the UK, and where the real boundary lies
Kept separate versus mixed with family funds
The difference that the courts make isn’t concerned with who got the money; it is about what was done with it afterwards. If an inheritance is held in a bank account in one spouse’s sole name, is clearly documented, has never been used for joint expenses or for the family home and has been kept separate throughout the marriage, this makes the strongest case for it being excluded. On the other hand, if the same inheritance is deposited into a joint account and has been used to pay down the family mortgage or to fund a loft conversion, it is much more likely to be considered matrimonial property. Maintaining a clear record from the time the money was received up to the present day is not merely a formality; it is the basis of the argument.
How trust assets are treated in England and Wales
Trust assets and those held in the name of a third party do not automatically come outside the court’s consideration. According to the principles set out in Charman v Charman [2005] EWCA Civ 1606, the key question is whether the trustees would be likely to advance capital or income to the spouse, immediately or in the foreseeable future, if asked to do so. Legal ownership is not decisive. In cases where a spouse has been receiving regular payments, can access capital at request, or set up the trust during the marriage, the court may regard the trust funds as a financial resource. Even if a trust is excluded from direct division, it can affect the amount of the award taken from the matrimonial assets, which is why specialist advice regarding trust arrangements is essential both before and during divorce proceedings.
Business interests and pensions: a different kind of complexity
Valuing and dividing business assets on divorce
A business which began before the marriage may be partly non-matrimonial, but growth in its value during the marriage that results from either spouse’s efforts is likely to be treated as matrimonial and shared, and contributions as a homemaker and parent carry equal weight to financial ones. Purely passive growth on a pre-marital asset, such as market-driven increases, may be treated differently. The business is usually valued by a forensic accountant, often a single joint expert instructed by both parties with the court’s permission, using asset-based, income-based, or market-comparison approaches. Typical resolutions are a buyout (in which one spouse retains the business and the other gets assets of equivalent value elsewhere), offsetting against other assets such as property or pensions, or, in rare instances, a sale. The general aim is to keep the business viable, but the court’s main obligation is to ensure fairness to both parties.
Pension sharing, offsetting and attachment orders
In England and Wales, the court must take pensions into account on divorce (section 25B of the Matrimonial Causes Act 1973). Pension savings built up during the marriage are usually treated as matrimonial, although the element accrued before the marriage or after separation may be argued to be non-matrimonial. There are three main ways of dealing with them: a pension sharing order involves transferring a specified percentage of the pension’s cash equivalent value to the other spouse, who receives a pension credit in their own name, thus achieving a clear division; pension offsetting enables one spouse to retain their own pension while the other gets a larger share of the family home or savings, although this method does require a reliable comparison of the values in question; and pension attachment, which is used less often, leaves the recipient dependent on the pension member’s decisions about when to draw benefits. With respect to defined-benefit schemes, the cash equivalent transfer value may not reflect the true value of the benefits, so a report from a pension on divorce expert is often advisable before any decision is made.
Practical steps to protect non-matrimonial assets
Pre-nuptial and post-nuptial agreements
Since the decision in Radmacher v Granatino [2010] UKSC 42, the courts in England and Wales will give effect to a pre-nuptial agreement that was freely entered into by each party with a full appreciation of its implications, unless in the circumstances it would not be fair to hold the parties to it. Pre-nuptial agreements are not automatically binding, but independent legal advice for each party and full financial disclosure are strongly recommended because they help show the agreement was entered into on that basis. A well-drafted agreement is able to specify the value of a business at the time of marriage, isolate inherited assets and indicate how any future increase in value should be handled. Similarly, post-nuptial agreements have the same function for couples who are already married and can be a sensible choice when there are changes in circumstances, for example when someone receives a large inheritance or when they start a new business.
Deeds of trust, record-keeping and timing
A declaration of trust (often called a deed of trust) records how the beneficial ownership of a property is held, for example in unequal shares, making the arrangement clear from the beginning. It does not bind the court in divorce proceedings, which can still make orders over the property under the Matrimonial Causes Act 1973, but it can be useful evidence of where the money came from and what the parties intended. In the case of inheritances, it is important to hold the funds in an account in your sole name rather than a joint one and to keep a full record in writing, comprising bank statements that show where the money came from, the will and the estate accounts or correspondence from the executors showing what you received, as this greatly strengthens any future argument that the funds are non-matrimonial. Timing also matters.
Transferring or restructuring assets once a relationship is in difficulty can be challenged under section 37 of the Matrimonial Causes Act 1973, which allows the court to restrain or set aside a disposition made with the intention of defeating a claim for financial relief. Where a disposition made less than three years before the claim would have that effect, the intention is presumed unless the contrary is shown. It is always much more effective to act early, before a dispute occurs, than to try to restore the situation afterwards.
When specialist advice makes the difference
A hypothetical example
Consider this scenario: a client inherits a large sum from a parent early in their marriage. If the money has always been kept in a sole-name account, has been carefully documented, and a declaration of trust records the beneficial ownership of a buy-to-let property bought with that money, a strong case can be made for exclusion at the financial remedy stage. In such cases, if the courts accept the argument, the client may be able to keep most or all of the value of the inheritance, provided the other spouse’s needs can be met from the matrimonial assets. Results of this kind depend on the quality of the documentation, not merely on the legal argument.
How Buchanan & Co Solicitors assesses disputed assets
Our method begins by looking at the date on which each asset was bought, the way in which it was held and used during the marriage, whether the records support a claim that the asset is not marital, and whether the other person’s needs could actually be met using only the marital assets. Because of our extensive experience in family law and the fact that we have represented clients in Staveley, Chesterfield, Sheffield and Kiveton Park, we are able to determine which assets have a real basis for being excluded and where the risks are highest. We provide an initial consultation on a fixed fee so that you will know right from the start where you stand. Discounts are available for Blue Light Card holders and NHS staff
The bottom line on protecting your assets
Courts in England and Wales do not divide assets on an automatic 50/50 basis, and some assets carry real arguments for exclusion. But none are automatically protected. The source of an asset matters. How it was treated during the marriage matters more. And the documentation you have to support your position matters most of all when it comes to making that argument hold up in proceedings.
Understanding what assets cannot be split in a divorce in the UK is only half the answer. The other half is having the documentation and legal strategy in place before a dispute arises, not after. Speaking with an experienced family law solicitor early, before a dispute crystallises, is often the most effective step you can take. If you are facing divorce or simply planning, contact the team at Buchanan & Co Solicitors to book a fixed-fee initial consultation.

Frequently asked questions
Is an inheritance split in a divorce in England and Wales?
Not automatically. An inheritance is usually treated as non-matrimonial property, which means it falls outside the principle that assets built up during the marriage are shared equally. However, the court can still use it if the other spouse’s or the children’s reasonable needs cannot be met from the matrimonial assets. How the money was used during the marriage also matters.
Can my spouse claim my inheritance if I kept it in my sole name?
Keeping an inheritance in an account in your sole name, and never using it for family expenses, gives you the strongest argument that it should be excluded. It is not a guarantee, though. If the matrimonial assets are not enough to meet both parties’ needs, the court may draw on it. Good records of where the money came from will support your position.
What does matrimonialisation mean?
Matrimonialisation is the process by which an asset that started as non-matrimonial, such as an inheritance, becomes matrimonial property, in whole or in part. Following the Supreme Court’s decision in Standish v Standish [2025] UKSC 26, the question is whether the parties treated the asset as shared over time. Paying inherited money into a joint account and using it for the family home is a typical example.
Are trust assets taken into account on divorce?
They can be. Even if a spouse does not own the trust assets, the court may treat them as a financial resource if the trustees would be likely to advance capital or income to that spouse, now or in the foreseeable future, if asked. Regular distributions and the spouse’s role in setting up the trust can be relevant.
Is a business I owned before marriage protected in a divorce?
The value of the business at the date of the marriage may be treated as non-matrimonial. Growth in its value during the marriage that results from either spouse’s efforts is likely to be treated as matrimonial and shared. The business will usually need to be valued by an expert, and the outcome often involves one spouse keeping the business while the other receives other assets.
Are pre-nuptial agreements legally binding in England and Wales?
Pre-nuptial agreements are not automatically binding. However, since Radmacher v Granatino [2010] UKSC 42, the courts will give effect to an agreement that each party entered into freely, with a full appreciation of its implications, unless it would be unfair to hold them to it. Independent legal advice and full financial disclosure are strongly recommended. Post-nuptial agreements are treated in the same way.
Does a declaration of trust protect property if I divorce?
No. A declaration of trust records how the beneficial ownership of a property is held. It does not stop the divorce court from making orders over that property under the Matrimonial Causes Act 1973. It can, however, be useful evidence of where the purchase money came from and what the parties intended.
Can I move assets to protect them before a divorce?
Moving assets to defeat a financial claim can be challenged. Under section 37 of the Matrimonial Causes Act 1973, the court can stop or set aside a transaction made with that intention. If a transaction made in the three years before the claim would have that effect, the intention is presumed unless shown otherwise. Planning should be done early and openly, ideally through a nuptial agreement.
Are pensions split on divorce?
The court must take pensions into account, and pension savings built up during the marriage are usually treated as matrimonial. They can be dealt with through a pension sharing order, by offsetting the pension against other assets, or through a pension attachment order. Pension built up before the marriage may be argued to be non-matrimonial.
