Expert Guide: Clean Break Orders and Capitalising Maintenance
1. Why Courts Prefer Clean Breaks
Section 25A of the Matrimonial Causes Act 1973 directs the court to consider whether it would be appropriate to terminate financial obligations as soon as is just and reasonable. This is the statutory basis for the clean break principle.
Courts favour clean breaks for several compelling reasons: they promote finality and certainty; they allow both parties to rebuild their lives without ongoing financial dependency; they reduce the risk of future litigation as circumstances change; and they are generally considered fairer to the payer in long-term relationships where the payer's earning power may diminish.
An immediate clean break is not always achievable — particularly where one party has been out of the workforce for many years raising children, has a disability, or has care responsibilities that prevent full employment in the short to medium term. In these cases, the court may make a term order (fixed period of maintenance) with or without a Section 28(1A) bar, or a nominal order (£1 per year) to preserve future rights.
The clean break is typically achieved through the capital settlement: if the payer has sufficient assets, they can pay the recipient a lump sum (the capitalised value of the maintenance stream) and both parties walk away with no further financial obligations to each other.
2. The Duxbury Calculation — Methodology and Tables
The Duxbury calculation, named after Duxbury v Duxbury [1987], is the standard method for capitalising a periodical payments obligation in English and Welsh family law. The calculation answers the question: "What lump sum, if invested today at an assumed real rate of return, would generate the required maintenance income for the recipient's expected remaining lifetime, exhausting itself at the point of death?"
Key assumptions in the Duxbury Tables:
- Investment return net of tax: currently assumed at approximately 3.0–3.75% per annum in real terms
- Life expectancy: based on ONS mortality tables for England and Wales
- Income tax: calculated on the assumed gross investment income
- Inflation: the capital grows in real terms; the maintenance figure is in today's money
The Duxbury figure is always significantly less than the simple multiplication of maintenance × years, because the capital earns investment income throughout the period while being drawn down. For example, £2,000/month for 10 years undiscounted = £240,000; the Duxbury capitalised value might be £165,000–£185,000 depending on age and assumed returns.
The published Duxbury Tables (At A Glance, updated annually by Class Legal) are the approved reference for courts and solicitors. They provide a table based on the recipient's age and required annual net income. Always use the current year's tables, as the assumed returns change annually to reflect market conditions.
3. Risks of Maintenance vs Lump Sum — Who Wins?
Risks of ongoing maintenance (for the recipient):
- Remarriage automatically terminates the order — leaving the recipient without income if the new relationship also fails
- Payer's death terminates a joint lives order (though some protection may be obtained by insisting on life insurance)
- Payer's income reduction may trigger a variation application reducing payments
- Payer's non-compliance — enforcement is costly and stressful
- Cohabitation may be grounds for a variation reducing the order
Risks of taking a lump sum (Duxbury) instead:
- Investment risk — the lump sum may underperform assumed returns
- Longevity risk — if the recipient lives longer than actuarially expected, the capital may be exhausted
- Inflation risk — fixed lump sum may lose purchasing power over time
- Inflexibility — once accepted, the recipient cannot return to court for more
Who benefits from taking the lump sum? Younger recipients with strong investment management skills and lower life expectancy risk (or alternative income in later life) often benefit from taking capital and achieving true independence. Older recipients approaching retirement with no other pension assets may be better served by periodic maintenance or a larger pension share.
4. Term Orders, Step-Down Provisions and Section 28(1A) Bars
Where an immediate clean break is not possible but the court anticipates the recipient achieving financial independence within a defined period, a term order is preferred over a joint lives order. The term is set based on when the recipient can reasonably be expected to be self-sufficient — for example, when the youngest child starts school and the recipient can return to full-time work.
Step-down provisions are orders where the maintenance reduces over time — for example, £2,500/month for years 1–3, £1,500/month for years 4–6, then ceasing. This mirrors the recipient's anticipated increasing financial independence and is particularly suitable where the recipient is retraining or increasing their hours of work gradually.
Section 28(1A) bar: When making a term maintenance order, the court can include a direction that the recipient cannot apply to extend the term. This is a significant protection for the payer, as without the bar the recipient can apply at any time before the order expires to seek an extension (Flavell v Flavell [1997] principle). Inserting the bar provides the payer with certainty that the obligation will end on the specified date.
Where the term order includes a s.28(1A) bar, the recipient's only option if they have not achieved independence by the expiry date is to argue that making the order expire would cause exceptional financial hardship — a high bar (Richardson v Richardson [1994]).
5. Tax Treatment of Spousal Maintenance in 2026
The tax treatment of spousal maintenance payments was fundamentally changed by the Finance Act 1988. The current position is:
- For payments made under orders made on or after 15 March 1988: Maintenance payments are not deductible by the payer and are not taxable income for the recipient
- This is the default position for all modern orders
- Maintenance does not count as earnings for pension contribution purposes
- Maintenance may affect Universal Credit and other means-tested benefit calculations
The exception to the non-taxability rule is where the Married Couple's Allowance or Maintenance Relief applies to orders made before 15 March 1988 — this is now largely of historical interest only.
Tax implication of the Duxbury lump sum: The lump sum itself is not taxable on receipt. Investment income and gains generated by the invested capital are taxable in the recipient's hands in the normal way (subject to their ISA, capital gains annual exempt amount, and personal allowance). The recipient should take independent financial advice on how to invest the Duxbury lump sum tax-efficiently.
6. Nominal Orders — Preserving Future Rights Without Immediate Payment
A nominal maintenance order — typically £1 per year or per month — is an order that creates a maintenance obligation in name only, with the purpose of preserving the recipient's right to apply to the court for substantive maintenance if their circumstances change materially in the future.
Nominal orders are used where: (a) the recipient is currently financially self-sufficient but may face future financial difficulties (e.g. due to health, caring responsibilities, or economic changes); (b) the payer does not currently have sufficient capital or income to pay maintenance; or (c) the parties want to achieve the closest thing to a clean break while retaining a safety net.
A nominal order is not the same as a clean break — it keeps the door open to future maintenance claims. However, the recipient would need to demonstrate a material change of circumstances to obtain a substantive order on a variation application.
The dismissed dismissal: Some solicitors argue for an "enduring nominal order" rather than dismissal of the maintenance claim, on the basis that dismissal forecloses options. However, a true clean break (with all claims formally dismissed) provides greater certainty and is generally preferred by courts and payers alike.
7. Mesher Orders and Martin Orders — Deferred Property Clean Break
Where the parties cannot achieve an immediate clean break in relation to the family home (usually because the primary carer of children cannot be adequately rehoused from an immediate sale), the court can make a Mesher Order or Martin Order.
Mesher Order (deferred sale): The property is held on trust for sale, with the sale deferred until a trigger event. Common trigger events include: the youngest child reaching 18, leaving secondary education, or completing tertiary education; the occupying spouse's death; the occupying spouse's remarriage or cohabitation; or the occupying spouse voluntarily vacating the property. Each party retains their specified beneficial interest (e.g. 60:40 or 70:30 depending on the overall settlement). The non-resident party receives their share of the equity when the property is eventually sold.
Martin Order: Similar to a Mesher Order but used where there are no children — typically for older parties where the occupying spouse cannot be re-housed. The sale is deferred until the occupying party dies, remarries, or voluntarily vacates. The non-resident party's share is similarly deferred.
Disadvantages of Mesher / Martin Orders: They leave the financial relationship between the parties unresolved for many years. The non-resident party cannot draw on their equity share until the trigger event. If property values fall, the non-resident party bears that risk. Disputes frequently arise at the trigger event about condition, timing, and valuation. They should be avoided where possible — an immediate sale with adequate rehousing is cleaner.
Maintenance vs Clean Break — Common Mistakes
1. Agreeing Maintenance Without a Section 28(1A) Bar — Unlimited Future Exposure
If you agree to pay maintenance for a fixed term without including a Section 28(1A) bar, the recipient can apply at any time before the order expires to extend it. This completely defeats the purpose of a term order for the payer.
Always insist on a s.28(1A) bar unless the recipient's circumstances are so exceptional that the court would not impose one (for example, severe disability with uncertain prognosis). The bar should be a non-negotiable element of any term order from the payer's perspective.
2. Not Securing Life Insurance to Protect Maintenance Payments
A joint lives maintenance order terminates on the payer's death. This leaves the recipient with no income and potentially homeless if they have not maintained sufficient capital reserves. Courts can, and often do, direct the payer to maintain a life insurance policy (decreasing term or level term) to cover the maintenance obligation in the event of their premature death. This protects the recipient and should be included in any settlement where a joint lives order is made.
Without life insurance, the recipient may be forced into a variation application against the payer's estate — a stressful and potentially fruitless process if the estate is insufficient to meet the claim.
3. Accepting the Duxbury Figure Without Checking Against Current Tables
The Duxbury Tables are updated annually to reflect changing assumptions about investment returns and life expectancy. Using last year's tables (or a simple calculator that doesn't use the current tables) can produce a figure that is 5–15% higher or lower than the correct current Duxbury amount.
Always ensure your solicitor references the current year's At A Glance tables when calculating the Duxbury figure. For maintenance orders above £50,000/year, the difference in capitalised value between one year's tables and the next can easily exceed £20,000 — well worth verifying against the official current figures.

Worked Example: Duxbury Capitalisation
Example: £2,000/Month Maintenance for 8 Years — Duxbury vs Simple Total
Wife is 48, requires £2,000/month (£24,000/year) for 8 years. She has no other significant income. Basic rate taxpayer. Assumed Duxbury rate: 3.5%.
- Simple total (undiscounted): £2,000 × 12 × 8 = £192,000
- Duxbury capitalised estimate (3.5% rate, 8 years, age 48): approximately £148,000–£162,000
- Saving to payer from capitalisation: approximately £30,000–£44,000
- Monthly income from lump sum at 4% drawdown: £148,000 × 4% ÷ 12 = £493/month
- To generate £2,000/month at 4%: capital required = £2,000 × 12 ÷ 4% = £600,000 (perpetuity — not Duxbury which depletes)
