The 20/20/20 rule lets an unremarried former spouse of a service member keep TRICARE coverage, commissary and exchange access, and a direct share of retirement pay after a military divorce.
To qualify, the marriage must have lasted at least 20 years, the service member must have at least 20 years of creditable service, and those two 20-year periods must overlap. Falling short of any one requirement changes which benefits, if any, survive the divorce.
Each part of the 20/20/20 rule stands on its own, and missing even one disqualifies a former spouse from full benefits.
The marriage itself must have lasted 20 years or more. The service member must have performed at least 20 years of service that counts toward military retirement. Finally, those two 20-year periods have to overlap for the full 20 years, meaning the marriage and the creditable service ran together the entire time.
The overlap requirement trips people up the most. A couple married for 25 years does not automatically qualify if the service member only served the last 18 of those years, because the marriage and the creditable service did not overlap for a full 20 years. The math must work both ways before a former spouse can rely on the rule.
A former spouse who satisfies the 20/20/20 rule can keep TRICARE under their own name and Social Security number, according to TRICARE’s official eligibility guidance. Coverage is not automatic.
The former spouse has to register in the Defense Enrollment Eligibility Reporting System and provide the marriage certificate, divorce decree, and proof of the service member’s creditable service before benefits take effect.
Alongside TRICARE, a 20/20/20 former spouse keeps access to the commissary, the military exchange, and other installation privileges for as long as they remain unmarried. Once eligibility is confirmed, the Defense Department issues a new identification card in the former spouse’s name.
Base personnel will check that card going forward, not the original marriage certificate.
It helps to keep the 20/20/20 rule apart from a related but different threshold called the 10/10 rule. The 10/10 rule only controls whether the Defense Finance and Accounting Service, or DFAS, can pay a former spouse’s share of retirement pay directly instead of routing it through the service member.
A former spouse can qualify for direct DFAS payments under the 10/10 rule without meeting the fuller 20/20/20 threshold for TRICARE and commissary access, and the reverse is also true.
Florida courts can divide military retired pay as a marital asset in a divorce even when neither the 20/20/20 rule nor the 10/10 rule applies.
The difference is only in how the payment gets made. Without the 10/10 overlap, the former spouse’s share must still come directly from the service member, which can create collection problems if payments are missed.
A former spouse who does not reach the full 20-year overlap may still qualify under a narrower standard known as the 20/20/15 rule, described by Military OneSource.
Under this version, the marriage and creditable service only need to overlap by 15 years instead of 20. Qualifying spouses receive one year of transitional TRICARE coverage after the divorce, but they do not keep commissary or exchange privileges.
Meeting the 20/20/20 rule on paper is not the same as having benefits activated. A former spouse still has to bring the marriage certificate, the divorce decree, and proof of the service member’s creditable service to a military identification office before DEERS will reflect the change.
Gaps or inconsistencies between those documents and the divorce judgment can delay the process, sometimes for months.
It also helps to request written confirmation of eligibility from the service member’s branch before relying on any benefit.
The service personnel component, not the divorce court, makes the final call on whether the creditable service dates line up with the marriage, so a Florida judge’s ruling on property division does not automatically settle the military side of the analysis.
Remarrying ends TRICARE, commissary, and exchange privileges under either the 20/20/20 or 20/20/15 rule.
If that later marriage ends through divorce, annulment, or death, some former spouses can apply to have benefits reinstated, though reinstatement is not automatic and has to be requested through the correct military channel.
These federal rules apply no matter which state handles the divorce, but the Florida judgment and any supporting order still need to accurately document the marriage dates, the service member’s branch, and the retirement details.
DEERS and DFAS rely on that paperwork to confirm eligibility, so a judgment that is vague about dates or service history can slow down a former spouse’s access to benefits later.
