TL;DR: Military couples face a unique mix of federal and state rules. The USFSPA governs how courts can divide a military pension (formally called “retired pay”), the 10/10 rule controls whether DFAS pays a former spouse directly, the 2017 NDAA "frozen benefit" rule fixes the pension amount at the date of divorce, and the SCRA can pause divorce proceedings during active duty. A prenup is the cleanest place to decide how all of this will work before you marry.Military life builds a marriage on a different foundation than most. Orders move you across the country or around the world. Deployments interrupt jobs, school, and the rhythms of daily life. Benefits that civilians never think about (housing allowances, survivor annuities, a pension earned over twenty or more years) become central to your family's financial picture. According to the Department of Defense's 2024 Demographics Profile of the Military Community , roughly half of active-duty service members are married, which means a large share of military families are navigating these federal benefit rules alongside ordinary state marriage law.
A prenuptial agreement gives you a way to sort through that overlay calmly, before a wedding and long before any divorce. For service members, it's a chance to spell out how career-earned benefits will be treated. For the future spouse, it's a chance to understand what they're agreeing to and to make sure their own contributions and concerns are reflected. If you're new to the concept, our prenup primer covers the basics in plain language.
Why military couples often benefit from a prenup Most prenup questions sit inside one body of law: the family code of the state where you live or plan to divorce. Military couples carry an extra layer. Federal statutes shape how a pension can be divided, how survivor benefits work, how housing allowances are paid, and even whether a divorce can proceed while one spouse is deployed. State law still drives the agreement itself, but the federal pieces interact with it at every turn.
Without a prenup, default state rules decide how marital assets are split, and federal mechanics decide what counts as divisible military pay and how it gets paid out. With a prenup, you and your partner get to make many of those decisions on your own terms, with full information and time to think. That's true for any couple, and it's especially valuable when one or both of you is in uniform and your career path includes promotions, deployments, and a pension that may take decades to vest fully.
How a military pension gets divided: USFSPA, the 10/10 rule, and the frozen benefit rule Three federal rules shape almost every conversation about dividing a military pension. Understanding them in order makes the rest of the planning much easier.
The first is the Uniformed Services Former Spouses' Protection Act , codified at 10 U.S.C. §1408 . The USFSPA is the federal law that lets state courts treat disposable military retired pay as marital property and divide it in divorce. It does not require any particular division; it gives state courts the authority to apply their own marital property rules to the pension. In a community property state, that might mean an equal split of the marital share. In an equitable distribution state, it might mean something different, and "equitable" doesn't always mean "equal."
The second is the 10/10 rule. This one is widely misunderstood. The 10/10 rule requires 10 years of marriage overlapping with 10 years of creditable military service for the Defense Finance and Accounting Service to pay a former spouse's share of the pension directly. It does not decide whether the former spouse is entitled to a share. That is a state court question. If the 10/10 threshold isn't met, a former spouse can still receive a portion of the pension if a state court orders it; the service member simply pays the spouse directly instead of having DFAS handle the disbursement. Even when DFAS does handle the payment, federal law caps the direct payment at 50% of disposable retired pay (or up to 65% when child support or alimony is also being collected).
The third is the "frozen benefit" rule, created by Section 641 of the National Defense Authorization Act for Fiscal Year 2017 . Before 2017, a former spouse's share of a pension could effectively grow with the service member's later promotions and added years of service. Under the frozen benefit rule, for service members who divorce while still serving, the divisible pension is calculated based on the member's rank and years of service as of the date of the order, with cost-of-living adjustments added from the date of the order through retirement and afterward. Practitioner guidance from the ABA Family Law Section and the North Carolina State Bar's military legal assistance program explains the practical effect: post-divorce promotions and added years generally don't increase the former spouse's share.
Here's how those federal pieces fit together at a glance:
Rule
What it does
Why it matters for a prenup
USFSPA (10 U.S.C. §1408)
Allows state courts to divide disposable military retired pay as marital property
A prenup can specify how, or whether, the pension is divided
10/10 rule
Requires 10 years of marriage overlapping 10 years of service for DFAS direct payment
Affects payment mechanics, not entitlement; a prenup can address both
Frozen benefit rule (NDAA 2017, §641)
Caps the divisible pension at rank and years of service as of the date of the order
Reduces the moving-target problem; a prenup can build on this baseline
SCRA (50 U.S.C. §3932)
Allows active-duty stay of civil proceedings
Affects timing of any later divorce, not the prenup itself
SBP (10 U.S.C. §1447 et seq.)
Survivor annuity, elected separately from the pension
A prenup can require or waive former-spouse SBP coverage
What a prenup can (and cannot) do with a military pension A prenup is the right place to decide, in advance, how the pension will be handled if the marriage ends. Common approaches include a clean waiver of any claim to the other partner's pension, a defined formula that allocates only the marital share, or a fixed dollar carve-out. State law on enforceability still applies; a prenup that waives or limits a pension share is most defensible when both partners had full financial disclosure, time to review, and, in many states, independent legal counsel for each partner.
A few specific points are worth flagging. Disposable retired pay (the portion of military retirement pay eligible for division under federal law, after certain statutory deductions) is what USFSPA actually reaches; gross retired pay is not the same number. Disability pay generally isn't divisible under USFSPA, and there are special rules for Combat-Related Special Compensation. A prenup that addresses "the pension" should be drafted with these distinctions in mind so it survives both federal mechanics and state enforceability review. If the service member later elects a disability waiver that reduces the former spouse's share, the Supreme Court's decision in Howell v. Howell (2017) allows state courts to order indemnification for that reduction, and a prenup can address upfront whether and how such indemnification will apply.
The Survivor Benefit Plan is a separate decision from the pension itself. The SBP is a military annuity that pays a designated beneficiary a monthly amount after the retiree's death, and it is elected separately from how the pension is divided in any future divorce. Under 10 U.S.C. §1447 et seq. , if a former spouse is to receive SBP coverage, it must be addressed specifically in the divorce order or underlying agreement. A prenup can require, limit, or waive former-spouse SBP coverage. Couples often forget this piece, which can lead to estate plans, divorce orders, and SBP elections that contradict each other. Former-spouse SBP coverage also has strict procedural deadlines: it must generally be established with DFAS within one year of the divorce decree, and missing that window can permanently forfeit coverage, so any prenup commitment to SBP should be paired with a clear plan for timely election.
BAH, TRICARE, and other benefits a prenup can address Not every military benefit is a divisible asset. The Basic Allowance for Housing is a good example. BAH is paid to the service member, not to the spouse, and it isn't treated as a separate marital asset that gets divided in divorce. After divorce, BAH counts as income for purposes of calculating child support, and the rate a service member receives can change depending on dependents and where they live. A prenup that addresses housing usually focuses on how housing costs are shared during the marriage, rather than on dividing BAH itself.
TRICARE eligibility for a former spouse is set by federal rules, primarily the "20/20/20" framework (20 years of marriage, 20 years of service, 20 years of overlap). There is also a "20/20/15" rule: if the marriage and service overlap by at least 15 years (but less than 20), the former spouse may qualify for transitional TRICARE coverage for up to one year after the divorce. A prenup can't expand or shrink federal eligibility rules, but it can address how the couple will handle health coverage gaps and related costs if they ever separate. The GI Bill and other education benefits follow their own statutory framework, and the same principle applies: a prenup can shape the surrounding financial planning, even where it cannot rewrite the federal entitlement itself.
The practical takeaway is that a military prenup spends most of its energy on what state law actually controls (assets, debts, support, the marital share of the pension) and uses clear language to acknowledge the federal pieces that sit on top.
Deployment, the SCRA, and timing your prenup Deployment shapes the timing of almost every legal decision in a military marriage. The Servicemembers Civil Relief Act can pause a civil proceeding, including a divorce, when active-duty service materially affects a service member's ability to participate. Under 50 U.S.C. §3932, an active-duty service member may request a stay of at least 90 days, and additional stays are possible. The SCRA doesn't change the substantive rules of who gets what; it shifts the timing so a deployed service member isn't railroaded through a proceeding they cannot meaningfully attend.
For prenups, the timing concern runs the other direction. A prenup signed in the final days before a deployment, with no time to read carefully, no chance to ask questions, and no opportunity to consult independent counsel, is more vulnerable to a later challenge for duress or inadequate disclosure. The cleanest move is to start the conversation early, exchange financial disclosures with time to spare, and sign well before any deployment window. Our prenup checklist is a useful planning aid for sequencing the steps.
If a deployment is already on the calendar and the wedding is close, there are still ways to do this thoughtfully. Both partners should have real review time, ideally with independent counsel for each. Powers of attorney for financial and legal matters during the deployment can be put in place alongside the prenup, so the absent partner can manage their affairs at home. If circumstances make a pre-deployment signing impossible, couples can consult with independent legal counsel about a postnuptial agreement after the deployment ends in states that recognize postnuptial agreements. And if anything material changes after a prenup is signed, our piece on what to do when circumstances change walks through the options.
Frequently Asked Questions Can a prenup waive a spouse's right to a military pension? Yes, generally. Under the USFSPA, state courts can treat military retired pay as marital property, and the law also allows service members and spouses to agree in advance how retirement will be handled. A prenup that clearly waives or limits the spouse's share, includes full financial disclosure, and meets state contract requirements can be enforceable.
What is the 10/10 rule and does it decide who gets the pension? The 10/10 rule requires 10 years of marriage overlapping with 10 years of creditable military service for DFAS to pay a former spouse's share of the pension directly. It does not decide whether the former spouse is entitled to a share; that is a state court question. If 10/10 isn't met, the service member pays the spouse directly instead.
How does the "frozen benefit" rule affect pension division? Under Section 641 of the National Defense Authorization Act for FY 2017, the divisible pension for a service member who divorces while still serving is calculated using their rank and years of service as of the date of the divorce decree, plus cost-of-living adjustments. Post-divorce promotions and added years generally don't increase the former spouse's share.
Does BAH get divided in a divorce? BAH is paid to the service member, not the spouse, so it isn't divided as a separate marital asset. After divorce, BAH counts as income for purposes of calculating child support in most states, and which BAH rate the service member receives can change depending on dependents and housing arrangements at that time.
Can we sign a prenup right before a deployment? You can, but it isn't ideal. A prenup signed under time pressure, without enough review time, or without each partner having a real chance to consult counsel can be vulnerable to a later challenge for duress or inadequate disclosure. Plan to sign well before deployment, with both partners reviewing the agreement calmly.
Does the Servicemembers Civil Relief Act affect a military divorce? The SCRA can pause a divorce proceeding when active-duty service materially affects a service member's ability to participate. Under 50 U.S.C. §3932, a service member can request a stay of at least 90 days. The SCRA doesn't change the substantive rules of who gets what; it shifts the timing.
