The 10/10 rule does not mean what most people think

What the rule actually governs

The 10/10 rule is a payment mechanic. Meet it, and DFAS will pay the former spouse’s share directly from the retired pay. Fall short of it, and DFAS will not.

That is the whole of it. It determines who writes the check, not whether a share exists.

What it does not govern

It is not a divisibility rule. A court can still award a former spouse a share of disposable retired pay in a marriage shorter than that overlap. The share simply has to be paid by the member rather than by the agency.

The practical difference is collection risk, not entitlement. That is a real difference and worth negotiating around, but it is a different problem from having no claim at all.

Three federal thresholds that get confused with each other

Part of why this is muddled is that there are several federal military-divorce thresholds with similar shapes and completely different purposes.

• 10/10 — ten years of marriage overlapping ten years of creditable service. Governs DFAS direct payment only.
• 20/20/20 — twenty years of marriage, twenty years of service, twenty years of overlap. Governs continued TRICARE, commissary, and exchange privileges, subject to remarriage rules.
• 20/20/15 — twenty years of marriage, twenty years of service, fifteen to nineteen years of overlap. Generally one transitional year of TRICARE and nothing after.

What to do with this

If you were told you have no claim because the marriage was too short, that advice deserves a second look. The question to ask is whether the state court can award a share, which is a state-law question, not whether DFAS will administer the payment.
