Life in the armed forces brings its own pressures – frequent postings, moves at home and abroad, long periods apart, and a distinctive pension. For military couples, a prenup can add a welcome layer of certainty around a career that is anything but predictable. This guide explains what makes forces life different, how a prenup helps, and how to keep it fair.
What makes forces life different
Two features stand out. First, one partner’s career often dominates where the family lives, with postings and moves limiting the other partner’s ability to build their own career and earnings. Second, there is the Armed Forces Pension, which – like any pension – can be shared on divorce and is frequently one of a couple’s most valuable assets. Add long deployments and time apart, and forces couples have good reason to want a clear financial plan (see who should consider a prenup).
The Armed Forces Pension
The Armed Forces Pension is valuable and, like other pensions, can be shared on divorce – so it is well worth addressing in a prenup rather than overlooking. A prenup can set out how the pension built up before the marriage is treated, while recording a fair approach to what accrues during it. Because valuing a pension properly means using its cash-equivalent transfer value, honest disclosure and sensible valuation matter here (see also protecting a pension and, for how pensions are dealt with on divorce, how pensions are split).
Fair provision for the partner who follows the postings
The partner whose own career has taken a back seat to postings and moves deserves fair recognition. Years of relocating, and periods unable to work, can dent earning power and pension provision just as they do for a stay-at-home parent. A fair military prenup makes proper provision for that partner rather than penalising them for supporting the serving partner’s career (see what to include). That fairness matters – a court will not uphold an agreement that leaves a partner stranded.
Postings abroad and jurisdiction
Overseas postings raise a practical wrinkle: if you marry or live abroad, questions of jurisdiction can arise about where a divorce would be dealt with. It is worth being aware of this and taking advice if your service takes you overseas long-term (see prenups for expats).
Keeping it fair
As always, the agreement must be fair and meet both partners’ needs, with the court keeping the final say (see are prenups legally binding?). For a mobile, demanding career, a clear and balanced prenup – kept current with a review clause – is simply good planning.
What a military prenup should address
A military prenup should address the two things forces life makes distinctive: the Armed Forces Pension, which – like any pension – can be shared on divorce and is often a couple’s biggest asset; and the impact of postings and frequent moves on the other partner’s own career and earning power. A fair agreement protects the pension you have built while making proper provision for a partner whose career has taken a back seat to service life.
Deployments, separation and clear records
Long deployments and periods apart are a fact of forces life, and they make one practical thing especially valuable: a clear, agreed record of the couple’s finances. A prenup, supported by honest disclosure, gives both partners a settled picture of what is separate and what is shared, which is reassuring when one of you is away for months at a time. It removes a layer of financial uncertainty from a life that already has plenty of it.
Service accommodation and the family home
Forces families often live in service accommodation rather than a home they own, which can delay getting onto the property ladder and shapes what "the family home" means on divorce. A prenup can take account of this – how any property you do own is treated, and how a partner who has moved from posting to posting is provided for (see the house in a divorce). A review clause helps as your housing situation changes over a career.
Valuing the Armed Forces Pension properly
The Armed Forces Pension deserves a closer look because it is so often a couple’s largest asset and so often underestimated. Like other pensions, its real worth on divorce is measured by its cash-equivalent transfer value (CETV), not by a monthly figure or a vague sense of what it might be. A long-serving member can have a pension whose CETV runs well into six figures – frequently more than the equity in any home the couple own. Because pensions can be shared on divorce through a pension sharing order, a prenup that stays silent on the pension leaves the biggest asset unaddressed. A military prenup should set out how the pension built up before the marriage is treated and take a fair approach to what accrues during it (see protecting a pension and how pensions are split).
The partner who follows the postings
Forces life asks a great deal of the non-serving partner, and a fair prenup should recognise it. Following postings around the country or abroad, often at short notice, can make it very hard to hold down a career, build seniority or accumulate a pension of one’s own. In that sense the partner who moves for the service is in a similar position to a stay-at-home parent: their support has a real cost to their own financial future. An agreement that ignored this and left them with little would be exactly the kind a court declines to uphold. A fair military prenup makes proper provision for that partner’s reduced earning power and pension (see making a prenup fair).
A worked example
Imagine a serving officer with fifteen years’ service and a substantial Armed Forces Pension, married to a partner who gave up a promising career to follow postings and raise the children in a series of service houses. A prenup can protect the pension built up before the marriage while sharing what accrues during it, and make genuine provision for the partner whose own career and pension suffered. Because forces families often live in service accommodation rather than owning a home, the agreement should also think about housing on divorce and about getting onto the property ladder (see the house in a divorce). A review clause keeps it current across a mobile career.
Short-notice weddings and signing in good time
Forces life sometimes compresses timelines – a posting date, a deployment window or a move can push a couple towards a quicker wedding than they first planned. That makes one point of good practice especially important: sign the prenup in good time, not in the final scramble before the ceremony. The Law Commission’s 2014 report suggested at least 28 days before the wedding, and an agreement signed under time pressure is far easier to challenge as having been made under duress (see when to sign a prenup and last-minute prenups). If a deployment is looming, start the conversation and the paperwork early so there is room to exchange disclosure, take advice each, and sign without a rush.
Injury, medical discharge and changing circumstances
A forces career can end unexpectedly – through injury, medical discharge or a change of plan – and that can transform a couple’s finances, from earning power to pension entitlement to housing. An agreement that assumed a full career may look very different if service ends early. This is exactly why a review clause matters for military couples: it builds in a commitment to revisit the terms after major life events, so the agreement keeps pace with reality. If circumstances change dramatically after the wedding, a postnuptial agreement can update the position on the same principles (see is my prenup still valid?).
Military prenup FAQs
Is the Armed Forces Pension split in a divorce?
It can be, like other pensions, so it is worth addressing in a prenup (see how pensions are split in a divorce).
Does a prenup work around postings abroad?
Yes, though if you marry or live overseas, jurisdiction matters (see prenups for expats).
How do I protect a partner who moves for my postings?
Make fair provision for their reduced earning power and pension (see stay-at-home parents).
How is a military pension valued for a prenup?
Using its cash-equivalent transfer value, honestly disclosed (see valuing assets).
Is a military prenup legally binding?
Not automatically, but a fair agreement made properly carries significant weight (see are prenups legally binding?).
When should forces couples sign, given short-notice postings?
As early as possible – the Law Commission suggested at least 28 days before the wedding – so a deployment or move does not force a rushed signing (see when to sign a prenup).
What if I am medically discharged after signing?
A review clause lets you revisit the terms after such a change, and a postnuptial agreement can update the position (see review clauses).
