We explain the difference between matriomonial assets and non-matrimonial assets
When a couple separates or divorces, one of the most important legal issues is how their finances will be divided. The courts in England and Wales look at what property and money should be considered part of the matrimonial pot and what may be kept separate. This often involves distinguishing between matrimonial assets, non-matrimonial assets, and considering whether ring-fencing is appropriate. To help you understand the difference, this article explains what might be shared during a divorce and what could remain outside the financial settlement.
What Are Matrimonial Assets?
Matrimonial assets are the financial resources built up during the marriage. These are generally the starting point for division when a couple separates. They reflect what the parties created together as part of their shared life.
Examples of matrimonial assets include:
- The family home, if it was bought during the marriage or paid for with joint funds.
- Other properties purchased together during the marriage.
- Savings, investments, and pensions built up during the marriage.
- Cars, household contents, and personal possessions bought while married.
- Business interests set up and grown during the marriage.
In principle, the court treats matrimonial assets as belonging to both parties, regardless of who earned or legally owns them. This reflects the law’s approach that marriage is a partnership and both parties contribute in different ways.
What Are Non-Matrimonial Assets?
Non-matrimonial assets are usually those that were acquired before the marriage or received independently of the marriage. The court may treat them differently from matrimonial assets, especially where the needs of the parties and children can be met without sharing them.
Common examples of non-matrimonial assets are:
- Property owned by one spouse before the marriage.
- Inheritances received by one party, even if received during the marriage.
- Gifts given to one party individually.
- Assets from previous relationships, such as pensions or savings.
- Businesses that were established before the marriage.
Non-matrimonial assets can, however, become mixed into the matrimonial pot. For example, if one party owned a property before the marriage, but it later became the family home and both parties contributed to it, the court may treat it as matrimonial.
The Court’s Approach to Division
The court does not apply rigid rules but instead considers fairness and the specific circumstances of the case. The key statute is section 25 of the Matrimonial Causes Act 1973, which sets out the factors the court must take into account. These include the welfare of any children, the needs of both spouses, the length of the marriage, and the financial resources available.
Where possible, the court seeks to divide matrimonial assets equally. However, the division of non-matrimonial assets is more flexible. If the couple has sufficient matrimonial property to meet their housing and income needs, the court may allow one spouse to retain their non-matrimonial property. But if needs cannot be met without using those resources, the court can order that non-matrimonial assets be shared.
The Concept of Ring-Fencing Non-Matrimonial Assets
Ring-fencing non-matrimonial assets means to protect them from being divided during the divorce process. In practice, it means keeping certain property outside the matrimonial pot, so that the other spouse has no claim to it.
Here are the most common situations where you might consider ring-fencing non-matrimonial assets:
- An inheritance received by one spouse and kept separate from joint finances.
- A property owned by one spouse before the marriage, which has not been used as the family home.
- A family business handed down through generations.
The court may ring-fence these assets if there are enough matrimonial resources to meet needs. But where the overall finances are limited, ring-fencing non-matrimonial assets may not be possible. For example, if a couple’s only home was inherited by one party, the court may decide it should still be treated as matrimonial because both spouses and any children need housing.
How Assets Can Become Mixed
Even where property begins as non-matrimonial, it can lose that status if it is mixed into the couple’s joint finances. This is sometimes referred to as “mingling”.
Examples include:
- Using an inherited lump sum to pay off the mortgage on the family home.
- Adding a spouse’s name to the deeds of a pre-marriage property.
- Putting inherited money into a joint bank account.
Once non-matrimonial property has been mingled, it is harder to argue that it should be ring-fenced. The court will usually treat it as part of the matrimonial pool available for division.
The Role of Needs
A central principle in family law is that the needs of both parties and any children must be met. This can override the argument for ring-fencing non-matrimonial assets. Even if an asset is clearly non-matrimonial, it may be shared if the alternative would leave one spouse or the children without sufficient housing or income.
For example, a spouse may inherit a large sum of money during the marriage. Ordinarily, this could be ring-fenced. However, if the other spouse has primary care of the children and cannot be housed without part of the inheritance, the court may decide that some or all of it should be used.
Prenuptial and Postnuptial Agreements
One way couples can influence how non-matrimonial assets are treated is by entering into a prenuptial or postnuptial agreement. These agreements can set out in advance what property should remain separate, which can help protect things like inheritances, family businesses, or property owned before the marriage.
The most important legal case on this subject is Radmacher v Granatino (2010). In that case, the Supreme Court said that if a nuptial agreement is made freely, with both parties understanding what it means, it should normally be upheld unless it would be unfair to do so. This marked a major shift, as the courts had previously been reluctant to give much weight to such agreements.
At present, prenuptial and postnuptial agreements in England and Wales are not automatically legally binding. The court will still look at whether the agreement is fair and whether it meets the needs of both spouses and any children. If an agreement leaves one party in serious financial difficulty, the court is unlikely to follow it in full.
There may, however, be changes in the future. The Law Commission has recently recommended that “qualifying nuptial agreements” should become legally binding if certain conditions are met. These would include requirements such as both parties receiving independent legal advice, making full financial disclosure, and allowing a period of time to reflect before signing. Parliament has also shown interest in reform, and public support for legally binding prenups has grown in recent years.
In practical terms, this means that while nuptial agreements can already be a strong tool for ring-fencing non-matrimonial assets, their role may become even clearer and more secure if reforms are introduced.
