The 20/20/20 rule: lifetime military benefits for a divorced spouse — and the fine print that ends them
A military divorce doesn’t automatically strip a former spouse of everything. Under the 20/20/20 rule, an unremarried former spouse who clears three 20-year tests keeps lifetime TRICARE, commissary, and exchange access — benefits worth tens of thousands of dollars over a lifetime. Miss the overlap by a few years and you drop to 20/20/15, which buys just one transitional year of health coverage. And one decision — remarriage — can end it all permanently. Critically, none of this is the same as dividing the pension, which is a separate question with its own rules. Here’s exactly how the tests work, what each tier gets you, and an eligibility checker.
1. The three 20-year tests
The 20/20/20 rule comes from the Uniformed Services Former Spouses’ Protection Act (USFSPA). To keep full military benefits after divorce, an unremarried former spouse must satisfy all three:
The member doesn’t have to be retired — the service just has to be creditable toward retired pay. For Guard and Reserve members, “creditable service” is measured in retirement points, not calendar years, so the overlap calculation requires a careful look at the points statement.
2. What 20/20/20 gets you
Clear all three tests and, as an unremarried former spouse, you receive military benefits as if the member had retired and you were still a dependent:
- Lifetime TRICARE — the same coverage options as a retired family member, for life (until you remarry or become covered elsewhere).
- Commissary, exchange, and MWR privileges — on-base shopping and recreation.
- Your own military ID — issued in your name once DEERS reflects your eligibility.
You enroll in TRICARE under your own Social Security number and will need your marriage certificate, divorce decree, and proof of the member’s service (DD-214 or a statement of service). TRICARE coverage alone can be worth tens of thousands of dollars over a lifetime, which is why establishing eligibility promptly matters.
3. The 20/20/15 fallback
If you meet the 20-year marriage and 20-year service tests but your overlap was at least 15 but fewer than 20 years, you fall under the 20/20/15 rule. That gets you one year of transitional TRICARE from the date the divorce is finalized — and no lasting commissary or exchange privileges. It’s a bridge to let you arrange other coverage, not a permanent benefit. After that year, you’re on your own for health insurance.
4. Remarriage ends it
Remarriage terminates 20/20/20 benefits. TRICARE ends, the military ID is revoked, and commissary and exchange access stops. If that later marriage itself ends — by death, divorce, or annulment — some privileges like commissary and exchange may be reinstated on application, but TRICARE eligibility generally does not automatically come back once lost through remarriage. The rules differ by benefit and none of it is automatic, so if you’re weighing remarriage while receiving these benefits, understand precisely what you’re surrendering — and confirm the reinstatement rules for each — before the ceremony.
5. The employer-plan trap
Even a fully qualified 20/20/20 former spouse loses TRICARE eligibility if they become covered by an employer-sponsored health plan. Coverage can be regained if the employer plan later ends, but this catches people who take a job with benefits and don’t realize it suspends their TRICARE. When comparing job offers or benefit elections, weigh the value of keeping military coverage against the employer plan — sometimes declining employer coverage to preserve TRICARE is the better financial move.
6. This is NOT the pension
The most common confusion in a military divorce: 20/20/20 has nothing to do with dividing the retirement pay. They’re separate questions with separate rules:
- Benefits (TRICARE / commissary / exchange) → governed by the 20/20/20 and 20/20/15 thresholds above.
- Pension division → governed by state courts under the USFSPA. Even a short marriage can be awarded a share of retired pay if the divorce order provides for it.
- The 10/10 rule (10 yrs marriage overlapping 10 yrs service) → a payment rule only: it determines whether DFAS pays the former spouse’s court-awarded share directly, not whether they get a share at all, and not any healthcare.
A 20/20/20 spouse automatically also meets 10/10, so they can receive both lifetime benefits and direct pension payments — but a spouse can qualify for one without the other. Keep the Survivor Benefit Plan separate too: former-spouse SBP requires a decree provision and a DFAS deemed-election notice within one year, regardless of 20/20/20.
7. Check your eligibility
Enter the years and whether the former spouse has remarried. This estimates which tier applies — confirm with DEERS and a military-divorce attorney.
The marriage & service
Estimate only. Actual eligibility is confirmed through DEERS with your marriage certificate, divorce decree, and the member’s service documentation. Pension division is a separate question. Not legal advice.
8. If you don’t qualify
Fall short of both thresholds and you generally lose TRICARE, your ID, and base access when the divorce is final. The main fallback is the Continued Health Care Benefit Program (CHCBP) — a COBRA-like option to buy up to 36 months of coverage comparable to TRICARE Select. Compare its premium against a marketplace or employer plan; sometimes it’s the cheaper bridge, sometimes not. Whatever your tier, act promptly: update DEERS, register TRICARE under your own SSN if eligible, and coordinate with DFAS on any court-ordered pension share so nothing lapses in the gap.
9. Frequently asked questions
What is the 20/20/20 rule?
The 20/20/20 rule, under the Uniformed Services Former Spouses’ Protection Act, lets an unremarried former spouse keep full military benefits after divorce — lifetime TRICARE, plus commissary, exchange, and MWR privileges — as if they were still a military dependent. To qualify, all three tests must be met: the marriage lasted at least 20 years, the service member performed at least 20 years of retirement-creditable service, and the marriage overlapped that service by at least 20 years. The former spouse gets their own military ID and enrolls in TRICARE under their own Social Security number.
What is the 20/20/15 rule and how is it different?
The 20/20/15 rule is a fallback for former spouses who meet the 20-year marriage and 20-year service tests but whose overlap was at least 15 but fewer than 20 years. It provides only one year of transitional TRICARE coverage from the date the divorce is finalized, and it does not grant lasting commissary or exchange privileges. After that transitional year, the former spouse must find other coverage. It’s a meaningful but temporary bridge — not the lifetime benefit that 20/20/20 provides.
Does remarriage end 20/20/20 benefits?
Yes. Remarriage terminates 20/20/20 benefits: TRICARE ends, the military ID is revoked, and commissary and exchange access stops. If the later marriage subsequently ends by death, divorce, or annulment, some privileges such as commissary and exchange may be reinstated on application — but TRICARE eligibility generally does not automatically resume once lost through remarriage. Because the rules differ by benefit and are not automatic, a former spouse considering remarriage should understand exactly what they’re giving up and confirm the reinstatement rules for each benefit before the ceremony.
Is the 20/20/20 rule the same as dividing the military pension?
No — they are entirely separate questions. The 20/20/20 rule governs healthcare and base privileges. Dividing military retired pay is governed by state courts under the USFSPA, and even a short marriage can be awarded a share of the pension if the divorce order provides for it. A different threshold, the 10/10 rule (10 years of marriage overlapping 10 years of service), only determines whether the Defense Finance and Accounting Service pays the former spouse’s court-awarded share directly rather than through the member. A 20/20/20 spouse automatically also meets 10/10, but the two rules answer different questions.
What are the options if you don't qualify for 20/20/20 or 20/20/15?
A former spouse who doesn’t meet either threshold generally loses TRICARE, the military ID, and base privileges when the divorce is finalized. The main fallback is the Continued Health Care Benefit Program (CHCBP), a COBRA-like option that lets the former spouse purchase up to 36 months of coverage comparable to TRICARE Select. It’s worth comparing CHCBP’s cost against a marketplace or employer plan. Separately, enrolling in an employer-sponsored health plan can suspend even a qualified 20/20/20 spouse’s TRICARE eligibility, so factor that in when weighing job offers with health coverage.
