The Matrimonial Causes Act 1973 and the section 25 factors
The Matrimonial Causes Act 1973 is the law that gives courts in England and Wales their powers over money, property and pensions on divorce[1]. Section 25 tells the judge to consider all the circumstances, putting first the welfare of any child under 18, and lists eight factors; there is no formula, and the court decides[2][3].

01/ The Act
What the Matrimonial Causes Act 1973 does
The Act has two main parts: Part I on divorce, nullity and other matrimonial proceedings, and Part II on financial relief for the parties to a marriage and the children of the family[1]. Under section 1, either or both of you can apply for a divorce on the ground that the marriage has broken down irretrievably[6].
Part II holds the court's financial powers: maintenance pending suit (section 22), periodical payments and lump sums (section 23), property adjustment orders (section 24), orders for sale (section 24A) and pension sharing orders (sections 21A and 24B)[1][7]. Sections 25 and 25A then say how the court decides whether and how to use those powers[1].
legislation.gov.uk records the Act as up to date with all changes known to be in force on or before 30 August 2026[1]. See how these powers come together in a financial settlement.
02/ Section 25(1)
All the circumstances, children first
Section 25(1) makes it the court's duty "to have regard to all the circumstances of the case, first consideration being given to the welfare while a minor of any child of the family who has not attained the age of eighteen"[2]. The Family Justice Council says housing is the priority, starting with a suitable home for the children with their main carer[8].
For orders for a child, section 25(3) adds the child's own financial needs, income and resources, any disability, and how the child was being, and was expected to be, educated or trained[2]. GOV.UK says arrangements for children come first and the reason for the divorce is not taken into account[9].
03/ Section 25(2)
The eight section 25 factors
Section 25(2) lists eight matters, (a) to (h), that the court must "in particular have regard to" for each of you[2].
04/ Section 25A
The clean break duty
Under section 25A(1), on or after a divorce the court must consider whether your financial obligations to each other should end "as soon after the making of the order as the court considers just and reasonable"[1]. It can dismiss a claim for maintenance with a direction that no further claim can be made[12].
If it orders maintenance, it must consider limiting it to a term long enough for the person receiving it to adjust without undue hardship[13]. The Family Justice Council says a clean break may not be fair or possible where there are children or the marriage has been long, and sometimes a nominal maintenance order is kept as a safety net[14]. More on spousal maintenance.
05/ Case law
Needs, compensation and sharing
The Act does not state what the court is aiming for[11]. In White v White, Lord Nicholls said that implicitly "the objective must be to achieve a fair outcome", giving first consideration to the children[11]. A judge should check their view "against the yardstick of equality of division", but that is not a presumption of equal division, which he said would be "an impermissible judicial gloss" on section 25[11].
In Miller v Miller; McFarlane v McFarlane the House of Lords described three strands of fairness[15]:
- Needs: "In most cases the search for fairness largely begins and ends at this stage", because the assets are not enough to provide for two homes[15].
- Compensation: "aimed at redressing any significant prospective economic disparity between the parties arising from the way they conducted their marriage"[15].
- Sharing: each is entitled to an equal share of the assets of the partnership "unless there is a good reason to the contrary", and equality is "an aid, not a rule"[15].
In Standish v Standish (2025) the Supreme Court said the sharing principle applies only to matrimonial property, the fruits of the marriage, while property brought into the marriage or inherited can still be used to meet needs or compensation[16]. The Family Justice Council says that where the assets do not exceed both partners' needs, assets from before the marriage or inherited during it go into the pot[8].
06/ No formula
There is no formula: the court decides
In White v White, Lord Nicholls said the Act gives the courts wide discretionary powers but does not state their aim; in Miller he said the Act gives "only limited guidance"[11][15]. The Family Justice Council says there is no set formula for maintenance either[18].
The Law Commission concluded in 2024 that it is not possible for someone going through divorce to understand, by reading the statute, how their case will be decided[3]. The Family Justice Council says most couples agree how to share their money and property without a judge deciding[8].
Even an agreed settlement is checked: a judge approves a consent order only if they think it is fair, and can ask you to change it[19]. The court can make the order on the information supplied unless it has reason to inquire further[20].
07/ Reform
Reform: where things stand, as at September 2026
The Law Commission's scoping report, published on 18 December 2024, concluded that financial remedies law needs reform but made no recommendations[3]. It found the law does not "provide a cohesive framework in which parties to a divorce or dissolution can expect fair and sufficiently certain outcomes", and set out four models: codification, "codification-plus", guided discretion and a default matrimonial property regime[3].
The Ministry of Justice consultation "A fairer end to relationships" ran from 5 June to 14 August 2026 and proposes a "codification-plus" model[17]. It would write the "needs" and "sharing" principles into law, with equal sharing of matrimonial property as the starting point unless unequal division is needed to meet needs, and a three-stage approach to needs with a child's welfare first[17]. It proposes keeping the section 25 factors largely as they are, adding a compensation factor for economic disadvantage suffered during the marriage, requiring the court to consider pensions, and introducing binding "qualifying nuptial agreements"[17].
As at 28 September 2026 the outcome had not been published, and the consultation says any legislation will be introduced when parliamentary time allows[17]. Until the law changes, section 25 and the case law above are what a court applies[1][16].
08/ Preparing
Preparing with section 25 in mind
Whether you agree in mediation, through solicitors or in court, the section 25 factors shape what a fair outcome looks like[2][21]. A mediator can help you agree how to split money and property without taking sides, and you must attend a MIAM before applying on Form A unless it is a consent order or an exemption applies[22][23]. See the Form A guide and financial disclosure.
Miam can help you work through each factor and list what you own, owe and need before a MIAM or mediation.
