Is there a fixed formula for spousal maintenance in the UK?

No. England and Wales do not have a statutory formula. Courts exercise wide discretion under the Matrimonial Causes Act 1973 section 25, with needs being the primary consideration.

What is a joint lives order and when is it granted?

A joint lives order continues until either spouse dies or the recipient remarries. They are typically reserved for very long marriages (20+ years) where the lower earner cannot realistically become self-sufficient.

Q: Can spousal maintenance be varied or ended early?

Yes. Either party can apply to vary, suspend or discharge a maintenance order if there is a material change in circumstances, such as job loss, significant income changes, or the recipient entering a new relationship.

Q: What is the clean break principle?

The clean break principle requires courts to consider whether it is appropriate to terminate financial dependency between parties. Where possible, courts prefer a one-off capital settlement over ongoing maintenance payments.

How UK Spousal Maintenance Works

Unlike child maintenance, there is no fixed formula for spousal maintenance (periodical payments) in England and Wales. Courts use a broad discretion under the Matrimonial Causes Act 1973, guided by the section 25 factors. The primary consideration is meeting the financial needs of the lower-earning spouse.

This calculator offers three perspectives: a needs-based estimate (the most common approach), a joint lives calculation for long marriages, and a term order estimate reflecting the modern preference for a clean financial break.

Key Principles

Needs-Based: Monthly maintenance = Monthly needs − Own net income − Child maintenance Joint Lives (long marriages): Monthly maintenance ≈ Income difference × 28–35% ÷ 12 Term Order: Duration ≈ Marriage length ÷ 2 years Monthly ≈ Income difference × 25% ÷ 12

Courts apply the "reasonable needs" test as the ceiling — the lower earner should not be left with less than their reasonable needs, but should not receive more than equalises incomes unless there are exceptional circumstances (such as very long marriages or poor health).

Section 25 Factors

Under the Matrimonial Causes Act 1973, courts must consider:

The income, earning capacity, property and financial resources of each party
The financial needs, obligations and responsibilities of each party
The standard of living enjoyed during the marriage
Age of each party and the duration of the marriage
Any physical or mental disability of either party
Contributions made to the welfare of the family (including homemaking)
Conduct of each party (in exceptional cases)
Value of any benefits either party will lose on divorce (e.g. pension)

Example Calculation

Example: 14-Year Marriage, 2 Children

Higher earner annual income£65,000

Lower earner annual income£18,000

Lower earner monthly net income~£1,170

Housing + living costs£3,000/mo

Child maintenance received£600/mo

Monthly shortfall (needs-based)~£1,230

Estimated term order7 years

A term order of 7 years at £1,230/month would total approximately £103,320 — giving the lower earner time to retrain or increase earnings before the order expires.

Frequently Asked Questions

No. England and Wales do not have a statutory formula like some other jurisdictions. Courts exercise a wide discretion under the Matrimonial Causes Act 1973 section 25. The overarching objective is fairness, with needs being the primary consideration. Scotland has a different system under the Family Law (Scotland) Act 1985, with shorter maintenance periods focused on economic disadvantage.

A joint lives order continues until either spouse dies, the recipient remarries, or the court varies or discharges it. They were historically common but courts now prefer term orders that encourage financial independence. Joint lives orders are typically reserved for very long marriages (20+ years) where the lower earner cannot realistically become self-sufficient due to age, health, or having sacrificed a career for family care.

Yes. Either party can apply to court to vary, suspend or discharge a maintenance order if there is a material change in circumstances — such as job loss, significant income changes, the recipient entering a new relationship, or retirement. Cohabitation (living with a new partner) is often grounds to reduce or end maintenance, though it does not automatically terminate it in the way remarriage does.

The clean break principle (s25A Matrimonial Causes Act 1973) requires courts to consider whether it is appropriate to terminate financial dependency between parties. Where possible, courts prefer a one-off capital settlement over ongoing maintenance payments, as it provides certainty for both parties. However, a clean break is not appropriate where one party cannot realistically become self-supporting, particularly in long marriages with primary carers of young children.

Maintenance payments under a court order are not taxable income for the recipient and are not tax-deductible for the payer (unless the order was made before 15 March 1988 or is maintenance for a former spouse who was born before 6 April 1935). This differs from the US and Canada where tax treatment of spousal support can significantly affect the negotiated amount.
