Your TRICARE status after divorce depends on who you are: the service member sponsor keeps coverage, biological and adopted children keep coverage, and a former spouse only keeps it by meeting the 20/20/20 or 20/20/15 rules. Update DEERS at an ID card office right away, since divorce triggers a 90-day TRICARE window. If you lose eligibility, CHCBP and Marketplace plans fill the gap.
TL;DR:
- A former spouse’s TRICARE eligibility after divorce depends strictly on meeting the 20/20/20 or 20/20/15 rules, with coverage lasting indefinitely or one year, respectively.
- Biological and adopted children retain TRICARE until their early twenties, while stepchildren lose coverage immediately on the divorce date unless legally adopted.
- Updating DEERS within days of the divorce decree and utilizing the 90-day window are critical to maintaining or establishing benefits and avoiding recoupment.
- Losing TRICARE eligibility requires action within 60 days to purchase CHCBP or enroll in a Marketplace plan; otherwise, coverage gaps could extend for months.
- An attorney experienced in military divorce can help craft decree language, manage DEERS documentation, and defend against recoupment claims.

Eligibility for sponsors and former spouses: the 20/20/20 and 20/20/15 rules
The sponsor keeps TRICARE regardless of the divorce outcome. A former spouse’s eligibility turns on three overlapping timelines, and getting even one wrong changes everything.
Under the 20/20/20 rule, a former spouse keeps TRICARE at retiree-level benefits, often indefinitely, when all three conditions are met:
- The marriage lasted at least 20 years.
- The sponsor served at least 20 years creditable toward retirement.
- The marriage and the service overlapped for at least 20 years.
Under 20/20/15, the marriage and service overlap for only 15 years instead of 20. That shortfall limits the former spouse to one year of transitional TRICARE coverage from the date of divorce, not a long-term benefit.
A former spouse who qualifies under 20/20/20 gets registered in DEERS under their own Social Security number or DoD benefits number, separate from the sponsor’s record. Remarriage ends that eligibility immediately, and so does enrollment in an employer’s health plan.
Children and stepchildren: who stays covered and typical age limits
Biological and adopted children keep TRICARE through the divorce without interruption, since their eligibility attaches to the sponsor, not the marriage. Coverage runs until early adulthood or the maximum age allowed for dependents, after which TRICARE Young Adult lets them purchase coverage until their mid-twenties.
Stepchildren are a different story entirely. Unless the sponsor legally adopted them, a stepchild loses TRICARE eligibility on the date the divorce is finalized, no exceptions for how long they lived in the household.
- Biological and adopted children: covered until 21, or 23 if in college, then TRICARE Young Adult until 26.
- Non-adopted stepchildren: coverage ends on the divorce date.
- When a child lives with the non-sponsor parent who has other health insurance, that plan typically pays first, and TRICARE acts as the secondary payer.
Immediate actions and timing: DEERS, the ID card office, and your enrollment windows
The clock starts the day your divorce is final, not when you get around to the paperwork. Three steps matter most in the first few weeks:
- Visit a local ID card office with a certified copy of your divorce decree and update your DEERS record immediately, since TRICARE will not retroactively excuse a delayed update.
- Use the 90-day TRICARE Qualifying Life Event window to change your TRICARE Prime or TRICARE Select enrollment, add or transfer dependents, or process a former spouse’s new eligibility status.
- If you lose TRICARE entirely, use the 60-day Marketplace Special Enrollment Period that starts from your loss-of-coverage date or divorce date, and bring proof of the divorce and the date coverage ended when you apply.
Missing either window can mean months without coverage, since open enrollment periods outside these windows are far more restrictive.
If you lose TRICARE: comparing CHCBP, Marketplace, Medicaid, and employer plans
Losing TRICARE eligibility does not mean going without coverage, but the options differ sharply in cost and duration.
- The Continued Health Care Benefit Program (CHCBP) must be purchased within 60 days of losing TRICARE, functions like a bridge policy, and in narrow cases (an unremarried former spouse under age 55) may extend beyond the standard term.
- A Marketplace plan purchased through the SEP can come with premium tax credits depending on income, and for some single filers the monthly premium ends up lower than CHCBP.
- Medicaid eligibility depends entirely on your state’s income and household rules, so check your state’s Medicaid agency directly rather than assuming you qualify or don’t.
- An employer-sponsored plan, when available, often beats both CHCBP and Marketplace coverage on cost once the employer contribution is factored in.
Marketplace plans with premium tax credits can offer lower premiums than CHCBP, depending on income. This is worth checking before defaulting to CHCBP, since many people overestimate its value compared to Marketplace alternatives.
Dependents who age out of standard eligibility can still buy TRICARE Young Adult rather than jumping straight to Marketplace coverage.
Financial risk and recoupment: how TRICARE audits catch delayed DEERS updates
TRICARE does not pay for care given to someone who was not actually eligible at the time, and when an audit uncovers a lapse, it can recoup those payments retroactively, sometimes going back to the divorce date itself.
The most common trigger is simple: a former spouse or non-adopted stepchild keeps using the sponsor’s ID card for care after eligibility ended, often because DEERS was never updated. Remarriage without notifying DEERS causes the same problem.
The fix is procedural, not complicated. Update DEERS the moment the divorce is final, stop using the sponsor’s ID card for anyone who has lost eligibility, and keep certified copies of the decree on hand in case TRICARE asks for proof of the eligibility date.
Pro Tip: Ask your attorney to include decree language assigning responsibility for any medical bills incurred during the transition period, since that clause can protect you if TRICARE later recoups a payment.
Document checklist: what to bring to the ID card office
Gathering the right paperwork before your visit saves a second trip and avoids a coverage gap while you wait.
- A certified, court-stamped copy of the divorce decree, plus your original marriage certificate.
- The sponsor’s DD Form 214 or a current Statement of Service showing creditable service dates.
- Your Social Security number or DoD Benefits Number for the new DEERS record.
- Custody orders or proof of a child’s other health insurance, if the children split time between households.
How a military-family law attorney can help with TRICARE issues in your decree
Most TRICARE disputes after divorce trace back to decree language that never addressed insurance at all. An attorney experienced in military divorce can draft specific clauses assigning responsibility for medical bills during the transition window, which directly reduces exposure if TRICARE later moves to recoup a payment.
That same attorney can help gather the DD Form 214, service statements, and decree copies DEERS requires, and can represent you if a recoupment letter arrives or eligibility gets disputed. An attorney experienced in military divorce and certified in mediation can provide significant assistance with these cases, including those involving high-conflict situations. Our guidance on TRICARE and the 20/20/20 rule covers how decree language can secure coverage.
Seek help promptly if you receive a recoupment notice, face a dispute over eligibility dates, or need custody terms that account for which parent’s insurance covers the children.
Author perspective: practical guidance from a Brevard County military divorce attorney
The paperwork is boring and the stakes are real. Update DEERS within days, not weeks, get several certified copies of the decree while you’re at the courthouse, and push for mediation that spells out insurance responsibility in plain language rather than leaving it assumed. A free consultation to review your decree language costs you nothing and can prevent a recoupment letter eighteen months from now.

FAQ
How long can a spouse keep TRICARE after divorce?
A former spouse who meets the 20/20/20 rule can keep TRICARE at retiree-level benefits with no fixed end date, as long as they don’t remarry or enroll in an employer plan. Under 20/20/15, coverage lasts one year from the divorce date instead.
How much does TRICARE cost after a divorce?
TRICARE itself does not charge a former spouse extra simply for being divorced, but a former spouse who loses eligibility entirely must pay for alternative coverage like CHCBP or a Marketplace plan. CHCBP must be purchased within 60 days of losing TRICARE, and Marketplace premiums vary by income and may be lower with tax credits.
Does a spouse get military benefits after divorce?
A spouse only keeps TRICARE and related benefits after divorce by meeting the 20/20/20 or 20/20/15 thresholds for marriage length, service length, and overlap. Falling short of either threshold ends eligibility on the divorce date, regardless of how the rest of the marriage looked.
What happens to TRICARE coverage for children after a military divorce?
Biological and adopted children keep TRICARE through age 21, or 23 if they’re full-time students, and can then purchase TRICARE Young Adult until 26. Stepchildren who were never legally adopted by the sponsor lose eligibility on the date the divorce is finalized.
