| Key Takeaways
• 20/20/15 unlocks transitional TRICARE and commissary access. The 10/10 rule does not grant access to these benefits at all; it governs retirement pay disbursement only. • All three rules are independent of retirement pay division. A court can divide military retired pay regardless of which threshold is met; the rules only affect which extra benefits and payment mechanisms apply. • Overlap years must be calculated precisely. Each rule uses a different overlap threshold (20, 15, or 10 years), and the service member’s creditable service record controls the math. • Order language decides the outcome. A decree that fails to specify overlap years, TRICARE transition, or SBP election can cost a former spouse benefits they are legally entitled to. |
Dividing benefits in a military divorce is rarely straightforward. Two sets of rules govern eligibility for different types of benefits, and they overlap in ways that confuse even experienced family law attorneys. The 20/20/15 rule and the 10/10 rule each serve a distinct purpose, and understanding the difference between them determines whether a former military spouse keeps access to healthcare, commissary privileges, and how military retired pay gets paid out. We handle these orders every day. Here is a plain-language breakdown.

Understanding the Three Military Divorce Benefit Rules
Federal law, primarily the Uniformed Services Former Spouses’ Protection Act (USFSPA), codified at 10 U.S.C. § 1408, governs how states can divide military retirement pay. Layered on top of that are administrative rules that determine which additional benefits a former spouse can access after divorce. Three threshold tests matter most.
The 20/20/20 Rule
Threshold: 20 years of creditable military service + 20 years of marriage + 20 years of overlap between the two.
A former spouse who meets all three thresholds is entitled to the fullest package of former-spouse benefits: ongoing TRICARE (the military healthcare program administered by the Department of Defense) coverage, commissary and exchange shopping privileges, and a military ID card for as long as they remain unmarried. This is the highest tier of protection for military former spouses and the outcome most clients hope to qualify for.
The 20/20/15 Rule
Threshold: 20 years of creditable military service + 20 years of marriage + 15 years of overlap (but less than 20 years).
The 20/20/15 rule applies when the marriage and the service career overlapped for at least 15 years but did not reach the 20-year overlap mark. Former spouses who qualify receive a one-year transitional period of TRICARE coverage and continued commissary and exchange access. After that transitional year, the TRICARE entitlement ends unless the former spouse obtains separate coverage. The retirement pay division right is unaffected; the court can still award a share of retired pay regardless.
The 10/10 Rule
Threshold: 10 years of creditable military service + 10 years of marriage + 10 years of overlap.
The 10/10 rule is a payment rule, not a benefits eligibility rule. It governs how the Defense Finance and Accounting Service (DFAS), the federal agency that disburses military retired pay, processes former-spouse payments. When the 10/10 threshold is met, DFAS can pay the former spouse’s court-awarded share of retired pay directly, rather than routing it through the service member. If the 10/10 rule is not met, the former spouse’s share must be collected from the service member directly, which creates enforcement risk. For the dedicated breakdown, see our guide to the 10/10 rule in military divorce.
Importantly, the 10/10 rule does not grant access to TRICARE, commissary, or exchange benefits. Those are governed exclusively by the 20/20/20 and 20/20/15 thresholds.
Side-by-Side Comparison: 20/20/20 vs 20/20/15 vs 10/10
Use this table to quickly identify which rule applies and what benefits are available under each threshold.
| Benefit / Eligibility Factor | 20/20/20 Rule | 20/20/15 Rule | 10/10 Rule |
| Service member active-duty years | 20+ years | 20+ years | 10+ years |
| Marriage duration required | 20+ years | 20+ years | 10+ years |
| Overlap (marriage + service) | 20+ years | 15+ years | 10+ years |
| TRICARE (military healthcare) | Yes, full coverage | Yes, 1-year transitional | No direct entitlement |
| Commissary and exchange access | Yes, ongoing | Yes, ongoing | No |
| Military ID card issued | Yes | Yes (1 year) | No |
| Direct payment from DFAS | Yes (if 10/10 also met) | Yes (if 10/10 also met) | Yes |
| Retirement pay division right | Yes | Yes | Yes |
What Happens to TRICARE Under the 20/20/15 Rule?
TRICARE is the military’s managed healthcare program. For former spouses, access after divorce depends entirely on which overlap threshold was met during the marriage.
- Under 20/20/20: TRICARE coverage continues indefinitely (until remarriage or Medicare eligibility).
- Under 20/20/15: TRICARE continues for one year from the date the divorce is finalized. After that year, the former spouse must transition to another plan, such as COBRA or a marketplace policy.
- Under 10/10 (without 20/20 overlap): No TRICARE entitlement. The former spouse is responsible for securing independent coverage from the date of divorce.
We see this issue create serious problems when divorce orders are drafted without clearly identifying which threshold applies. If the order does not specify the overlap years, DFAS and military benefits offices cannot make accurate determinations. Our military retirement division practice is built around getting this language exactly right.
How Retirement Pay Division Works Regardless of These Rules
It is a common misconception that a former spouse must meet the 10/10 threshold to receive a share of military retired pay. That is not accurate. State courts can divide military retired pay as a marital asset under the USFSPA in any divorce where the service member has creditable years of service. The 10/10 rule only determines how that share is paid out.
When the 10/10 threshold is met, DFAS pays the former spouse directly each month. When it is not met, a court can still award a percentage of retired pay, but enforcement falls to the former spouse through state court mechanisms if the service member does not pay voluntarily.
For a full breakdown of how military retired pay is calculated and divided, see our military retirement division service page.
Survivor Benefit Plan (SBP) and Benefit Continuity
The Survivor Benefit Plan (SBP) is a separate consideration. SBP provides a monthly annuity to a surviving former spouse if the service member dies before them. SBP eligibility for former spouses is not governed by the 20/20/20, 20/20/15, or 10/10 rules. It requires a specific court order and a timely election, independent of these thresholds. Without a proper SBP designation in the divorce order, a former spouse loses this protection permanently. For how SBP interacts with remarriage and ongoing pension payments, see our guide to military pensions, divorce, and remarriage.
Frequently Asked Questions
Does the 20/20/15 rule apply if the overlap was 14.5 years?
No. The 15-year overlap threshold is a hard minimum. Partial years may be counted depending on how creditable service is calculated, but 15 full years of overlap are required. If your case is close to the threshold, the exact calculation of creditable service dates becomes critical and should be verified against the service member’s official service record.
Can a former spouse qualify for both the 20/20/15 rule and the 10/10 rule?
Yes, and this is common. The two rules are independent tests. A former spouse can meet the 20/20/15 thresholds (qualifying for transitional TRICARE) and also independently meet the 10/10 overlap requirement (allowing DFAS to pay their share of retired pay directly). Meeting both thresholds is generally the best outcome for a former spouse.
What if the service member has less than 20 years of service?
Neither the 20/20/20 nor the 20/20/15 rule applies if the service member did not complete at least 20 years of creditable service. In that scenario, the only available threshold is the 10/10 rule for DFAS direct payment, and TRICARE access is not available through former-spouse military benefits. The former spouse would need to secure independent health coverage.
Does remarriage affect benefits under these rules?
Yes. Remarriage generally terminates TRICARE and other military former-spouse benefits, including commissary and exchange access. If the remarriage ends (through death or divorce), some benefits may be reinstated. The rules governing reinstatement are specific and vary by benefit type. For the detail on remarriage and pension continuity, see our guide to military pensions and remarriage.
Do these rules apply to National Guard and Reserve members?
The rules apply differently to Guard and Reserve members because their creditable service is calculated based on retirement points rather than active-duty years. If your divorce involves a Guard or Reserve retirement, the overlap calculation requires careful review of the member’s Retirement Points Statement. We handle Guard and Reserve military orders on a regular basis.
Why the Order Language Matters More Than People Realize
The benefit thresholds above are set by federal law, but the divorce order controls what actually happens. We have reviewed orders where the overlap period was never specified, where the TRICARE transition was not addressed, and where the SBP election was omitted entirely. In each case, the former spouse lost benefits they were legally entitled to, not because the law was unclear, but because the order language was.
Whether you are an attorney drafting the order, a spouse reviewing a proposed settlement, or a mediator helping both sides reach agreement, getting the threshold language correct at the time of the divorce is far less expensive than correcting it afterward.
