20/20/15 Rule vs 10/10 Rule: Military Divorce Benefits Explained

Dividing benefits in a military divorce is rarely straightforward. Two rules, the 20/20/15 rule and the 10/10 rule, determine what a former spouse can access after the marriage ends, but they apply to completely different benefits. Confusing them is one of the most common mistakes we see in military divorce cases.

Below, we break down exactly what each rule covers, how they compare, and what your situation means for TRICARE (the military healthcare program), commissary and exchange access, and retirement pay divided through the Defense Finance and Accounting Service (DFAS).

What Is the 20/20/15 Rule in Military Divorce?

The 20/20/15 rule sets a threshold for a former spouse to receive certain military benefits after divorce. To qualify, three conditions must all be true:

• The marriage lasted at least 20 years.
• The service member performed at least 20 years of creditable military service.
• At least 15 of those years overlapped, meaning the marriage and active service existed at the same time.

Former spouses who meet the 20/20/15 threshold are entitled to commissary and exchange privileges. However, they receive only one year of transitional TRICARE coverage after the divorce is finalized. This is the key distinction between the 20/20/15 rule and the 20/20/20 rule, full, permanent TRICARE eligibility requires a full 20-year overlap, not just 15.

What Is the 20/20/20 Rule? (The Full-Benefit Threshold)

The 20/20/20 rule is the higher standard. Here, the marriage, the military service, and the overlap between them all reach 20 years. A former spouse who meets this threshold receives:

• Lifetime TRICARE coverage (not just transitional),
• Commissary and exchange access, and
• Access to other installation privileges.

The 20/20/20 rule is the gold standard for post-divorce military benefit eligibility. The 20/20/15 rule applies specifically to those who fall just short, enough overlap to warrant some access, but not full healthcare continuity.

What Is the 10/10 Rule in Military Divorce?

The 10/10 rule governs something entirely different: how military retirement pay is paid, not whether a former spouse is entitled to it.

Under the 10/10 rule, DFAS can pay a former spouse’s court-ordered share of military retirement directly, but only if the marriage lasted at least 10 years and the service member performed at least 10 years of creditable service during that marriage.

When the 10/10 threshold is met, the former spouse receives their portion of retirement directly from DFAS each month, without depending on the service member to forward it. This direct-payment protection is significant: it removes one of the most common points of post-divorce conflict.

We handle the paperwork that makes DFAS direct payment possible. Learn how on our military retirement division service page.

20/20/15 vs 10/10 Rule: Side-by-Side Comparison

These two rules are frequently mentioned together but they operate independently. Here is how they compare across the benefits that matter most:

Criteria	20/20/20 Rule	20/20/15 Rule	10/10 Rule
Years of Marriage	20+	20+	10+
Years of Military Service	20+	20+	10+
Overlap Required	20 years	15 years	10 years
TRICARE (Full Coverage)	Yes	Temporary (1 year)	No
Commissary / Exchange Access	Yes	Yes	No
Retirement Pay (Direct DFAS)	Yes	Yes	Yes (if court-ordered)

What Happens If You Fall Below Both Thresholds?

If the marriage lasted fewer than 10 years, or the service overlap is less than 15 years, neither rule applies in full. That does not mean a former spouse is left with nothing.

Courts can still award a share of military retirement as part of a property division. The former spouse just cannot receive that share through DFAS directly, the service member must transfer funds under the court order instead. TRICARE and commissary access would not apply under these circumstances either.

Protecting benefit continuity for a surviving former spouse is a separate issue covered by the Survivor Benefit Plan. See our military retirement and SBP guide  for how that election works alongside the retirement division.

How We Help Military Spouses Navigate These Rules

We work with military families and family law attorneys across all branches of service, nationwide. Whether your case involves an Army colonel approaching 30 years of service or a recently separated Marine reservist, the rules governing post-divorce benefits are the same, and getting the order right matters.

Our team drafts the military-specific orders that divide retirement pay, coordinates with DFAS for direct-payment compliance, and ensures that SBP elections are addressed before finalization. We do not provide legal advice, but we understand the mechanics of these rules better than most.

Frequently Asked Questions

 

Does qualifying under the 20/20/15 rule mean I automatically get retirement pay?

No. The 20/20/15 rule only governs TRICARE access and commissary privileges, not retirement pay. Entitlement to a share of military retirement must be established separately through a court order and, if the 10/10 rule is met, submitted to DFAS for direct payment.

If my marriage was 18 years and overlapped 15, do I meet the 20/20/15 rule?

No. The 20/20/15 rule requires at least 20 years of marriage and 20 years of military service, the 15 refers only to the overlap. A shorter marriage does not qualify under either the 20/20/15 or 20/20/20 threshold, though retirement division may still be ordered by the court.

Can a court still divide military retirement if the 10/10 rule is not met?

Yes. Courts regularly award a portion of military retirement even when the 10/10 threshold is not met. In those cases, DFAS cannot pay the former spouse directly, the service member is responsible for forwarding the awarded amount each payment period under the court order.

Does the 20/20/15 rule apply to Guard and Reserve members?

Yes, though calculating creditable service for Guard and Reserve members involves reserve points rather than active-duty years. The same benefit thresholds apply, but confirming the precise overlap requires reviewing the service member’s official retirement points statement.

Can QDRO Masters help with the military retirement division even if we don’t meet the 10/10 rule?

Yes. Military retirement requires a specific type of court order that satisfies DFAS technical requirements. A standard divorce decree that simply says “retirement is divided” is typically not sufficient. The order must meet precise language and formatting standards to be accepted.

What is the difference between transitional TRICARE under the 20/20/15 rule and permanent coverage under 20/20/20?

Transitional TRICARE under the 20/20/15 rule lasts one year from the date of divorce and is not renewable. Permanent TRICARE coverage under the 20/20/20 rule continues indefinitely until the former spouse remarries or otherwise becomes ineligible. The one-year window gives time to find alternative coverage but does not substitute for long-term healthcare security.
