For a military spouse facing divorce after a long marriage, one question often outranks the pension: do I lose TRICARE?
The answer lives in a rule called 20/20/20, and the part everyone forgets is the third twenty.
The three twenties, and why the third one decides
Under 10 U.S.C. § 1072(2)(F), a former spouse keeps TRICARE in their own right when three things are all true: the marriage lasted at least 20 years, the member served at least 20 creditable years, and those two periods overlapped by at least 20 years.
The overlap is the trap. Twenty years married plus twenty years served qualifies nothing by itself. A marriage that began six years into a twenty-year career overlaps the service by only fourteen years, and fourteen is not twenty.
When all three twenties are met and the former spouse does not remarry, the coverage is not a courtesy extension. It is TRICARE in the former spouse's own name, under their own eligibility, after the divorce.
20/20/15: the one-year bridge
Close but not quite? There is a narrower rule. When the marriage and the service each hit twenty years but the overlap lands between fifteen and twenty, federal law (10 U.S.C. § 1072(2)(G) and (H)) provides transitional TRICARE for one year after the divorce.
One year goes fast. For the spouse in that window, the divorce settlement needs to plan what happens in month thirteen, not discover it.
Two ways to lose it
The statute gives, and two events take away. Remarriage ends a former spouse's TRICARE eligibility permanently, even if the new marriage later ends in divorce or death. And enrolling in an employer-sponsored health plan suspends it. Anyone weighing a new marriage or a new job's benefits package after a military divorce should run this math first.
It comes with the base privileges too
A 20/20/20 former spouse who has not remarried also keeps commissary and military exchange privileges, what the law now calls MWR retail facilities, under 10 U.S.C. § 1062. For a family that has shopped on base for two decades, that is a real piece of the monthly budget, and it rides on the same overlap rule as the health care.
Do not mix this up with the money rules
Military divorce has three different rules with years in them, and they answer different questions. 20/20/20 answers whether the former spouse keeps TRICARE and base privileges. Whether the retirement divides, and who pays the share, belong to entirely different rules.
Mixing them up has real costs. People assume a twenty-year marriage settled everything, when the benefits, the pension share, and the payment path each had their own clock. How the pension math itself gets locked is covered in our guide to the frozen benefit rule.
Count the years before you negotiate
If your marriage is at eighteen or nineteen years of overlap, the calendar itself is part of the conversation, and it is a conversation to have before anyone files. If the twenties are already met, the settlement should be built so nothing in it puts your own eligibility at risk.
