Spousal maintenance — ongoing financial support from one ex-partner to the other after divorce — is one of the things couples most often want to address in a prenup. You can, but there are firm limits on what an agreement can do. This guide explains what a prenup can say about maintenance, the limit a court will always keep, how spousal maintenance differs from child maintenance, and how to draft a clause that actually sticks.
What spousal maintenance is
Spousal maintenance is regular financial support paid by one ex-spouse to the other after divorce, usually to help the lower-earning partner adjust or to meet a shortfall between their income and their reasonable needs. It is separate from a division of capital, and separate again from how maintenance is decided when there is no agreement at all.
What a prenup can say
A prenup can set out your intentions on spousal maintenance: whether either partner would receive it, roughly how much, and for how long. Couples commonly use it to:
- Agree that each partner will be financially independent after divorce.
- Cap the amount or duration of any support.
- Provide for a defined period of support to allow a lower-earning partner to adjust.
- Record how support interacts with a capital settlement or a clean break.
The limit a court will always keep
Whatever the agreement says, a court can adjust spousal maintenance to make sure neither partner is left in real need. This is the same principle that runs through all of prenup law (see are prenups legally binding? and the needs principle): an agreement is given weight, but it is not allowed to leave someone unable to meet their reasonable needs. A clause that tries to cut a partner off entirely is exactly the kind a court is most likely to override, and it can make the whole agreement look unfair.
Can a prenup waive maintenance completely?
You can express the intention to waive maintenance, and where both partners are financially independent a court may well respect it. But a blanket waiver will not be enforced if it would leave a partner in genuine hardship. The realistic position is covered in can a prenup waive maintenance? — the short version is that intention is respected only so far as it remains fair.
Don’t confuse it with child maintenance
Spousal maintenance is support between the adults. Child maintenance is entirely separate, and a prenup cannot fix it — parents cannot contract out of supporting their children, and it is dealt with through the usual channels (largely the Child Maintenance Service) regardless of what an agreement says. See prenups and children for how the children backstop works.
Getting the balance right
A maintenance clause that is realistic and fair is far more likely to be followed than one that tries to cut a partner off entirely. Building it sensibly into the wider agreement — alongside everything else in what to include — is the way to make it stick. Pairing a maintenance clause with a review clause also helps, so the figure can be revisited if circumstances change dramatically.
Spousal maintenance in a prenup: how far can you go?
A prenup can set out spousal maintenance — whether either partner receives it, roughly how much, and for how long — and many couples use it to agree financial independence or to cap support. But there is a firm limit: a court can override a maintenance clause to make sure neither partner is left in real need. So a realistic, fair maintenance provision is far more durable than an attempt to cut a partner off entirely.
Term maintenance vs joint-lives maintenance
It helps to know the two shapes spousal maintenance usually takes. Term maintenance is paid for a fixed period — say three or five years — often to give a lower-earning partner time to retrain, return to work or otherwise get back on their feet. Joint-lives maintenance continues indefinitely, until one partner dies, the recipient remarries, or a court varies it. Courts in England & Wales increasingly favour term orders and a move towards independence where that is realistic, rather than open-ended support. A prenup can express a preference for a defined, tapering term over indefinite maintenance, and record the reasoning — which can carry real weight, provided it still meets the recipient’s reasonable needs at the time of divorce.
How a court assesses a maintenance clause
Because a prenup is not automatically binding, a court approaches a maintenance clause the same way it approaches the rest of the agreement. Following Radmacher v Granatino (2010), it gives real weight to what a couple freely and fairly agreed — but it retains its discretion under the Matrimonial Causes Act 1973 and measures the outcome against each partner’s needs. So a clause that says each partner waives all maintenance will be respected where both are genuinely self-sufficient, but reopened where one would otherwise be left unable to house or support themselves. The safeguards matter here too: full disclosure and independent advice make a maintenance clause far more likely to hold.
A worked example
Suppose Elena earns £90,000 a year and Marcus £24,000, and their prenup says each will be financially independent with no maintenance either way. If they divorce after a short marriage with no children and Marcus keeps his job, a court may well respect that clause. But if, ten years on, Marcus has given up work to raise their two children and has little recent earning history, the same clause would leave him in real need — and a court would step in, likely ordering a period of term maintenance to help him retrain and re-establish an income. The clause is not worthless in that scenario; it still signals the couple’s intention towards independence, which can shape how generous and how long any award is. It simply cannot be allowed to cause genuine hardship. This is why a stay-at-home parent is one of the situations where maintenance clauses need the most care.
Practical drafting tips
- Be realistic: a clause that reflects both partners’ actual earning capacity is far more durable than a blanket waiver.
- Prefer a defined, tapering term to an attempt to cut a partner off entirely.
- Record how maintenance interacts with the capital split and any clean break.
- Pair the clause with a review clause so the figure can be revisited if incomes or caring roles change dramatically.
- Keep child support entirely out of it — that is dealt with separately and cannot be fixed by agreement (see prenups and children).
Done this way, a maintenance clause becomes a genuine steer to a court rather than wishful thinking. See what to include in a prenup for how it fits with the rest of the agreement.
The provisions that fix the limits of a maintenance clause
Five sections of the Matrimonial Causes Act 1973 define what a maintenance clause can and cannot do. Section 34 makes void any term of an agreement that purports to restrict the right to apply to the court for financial provision, so a clause saying no maintenance will ever be paid is a nullity, though the rest of the agreement stands. Section 23 gives the court its power to order periodical payments for whatever term it specifies. Section 25A places the court under a duty to consider whether the parties' financial obligations to each other can be ended as soon after the divorce as is just and reasonable, and, where maintenance is ordered, whether a fixed term would let the recipient adjust without undue hardship; an agreement aiming at independence is pushing in the direction the statute already points. Section 28 ends periodical payments automatically when the recipient remarries, and section 31 lets either party apply to vary an order when circumstances change.
How far a court will hold a partner to an agreed cap is illustrated by Cummings v Fawn in 2023. Mr Justice Mostyn described needs as a range between a spartan bookend and a comfortable one and held that, where an agreement would leave a party below the spartan end, the court lifts them only just past it; an agreed limit is respected up to the point of real need and no further than needs require beyond it. That is the practical shape of the test in Radmacher v Granatino for maintenance: a stated level, a realistic term and a review if children arrive will usually be followed, and an attempt at exclusion will be replaced with whatever section 25 requires.
Spousal maintenance in a prenup: FAQs
Can a prenup stop spousal maintenance?
It can express the intention, but a court can override it to meet needs (see can a prenup waive maintenance?).
Is spousal maintenance the same as child maintenance?
No — child maintenance is separate, cannot be fixed by a prenup, and is dealt with through the usual channels (see prenups and children).
Can a prenup set a maintenance amount in advance?
It can record an intended amount or cap, but a court can adjust it if the figure would leave a partner in real need at the time of divorce.
What is a clean break, and can a prenup provide for one?
A clean break ends ongoing financial ties between ex-spouses. A prenup can express a wish for one, subject to needs being met (see clean break orders).
Does spousal maintenance always get paid on divorce?
No — it depends on each partner’s income and needs; many divorces end in a clean break with no ongoing maintenance at all (see spousal maintenance in the UK).
What is the difference between term and joint-lives maintenance?
Term maintenance is paid for a fixed period, often to allow a partner to become independent; joint-lives maintenance continues indefinitely until death, remarriage or a court variation.
Can a prenup encourage a clean break?
Yes — it can record a shared intention towards financial independence, which a court can respect where both partners’ needs are met (see clean break orders).
Does independent legal advice make a maintenance clause stronger?
Yes — advice for each partner, alongside full disclosure, is one of the safeguards that makes a court more likely to give a maintenance clause weight (see independent legal advice).
