COBRA After Divorce or Legal Separation: Costs and Deadlines

If you were covered under your spouse’s employer health plan, COBRA after divorce lets you keep that same coverage for up to 36 months, but you have to notify the plan administrator within 60 days of the divorce or legal separation becoming final, and you pay the full premium plus a 2% administrative surcharge yourself.¹ The benefits are identical to what active employees receive. Miss the 60-day notice window and you generally lose the right entirely, so the deadlines matter more than almost anything else in this process.

Who Qualifies

You qualify if you were covered under your spouse’s employer group health plan on the day before the divorce or legal separation became final.² Dependent children on the plan qualify independently. Each covered person becomes a “qualified beneficiary” with a separate right to elect coverage, so you can enroll yourself even if a child or your ex does not.

Federal COBRA applies only when the employer had at least 20 employees on more than half of its typical business days in the prior calendar year.³ Part-time workers count as fractions toward that threshold. If the employer is smaller than that, federal COBRA doesn’t reach you, though state continuation laws may.

If You Were Dropped Before the Divorce Was Final

Some employee spouses remove their partner from the plan before the decree is entered. Federal regulations disregard that move. If your coverage was reduced or eliminated in anticipation of the divorce, you still qualify for COBRA as if you had been on the plan the day before it became final.² Raise this with the plan administrator in writing and cite the anticipation-of-divorce rule.

The 60-Day Notice You Have to Send

Divorce and legal separation are qualifying events where the responsibility for telling the plan falls on you, not the employer. You have 60 days from the date the divorce or legal separation becomes final to get written notice to the plan administrator.⁴ Miss it and you generally forfeit COBRA rights entirely. Don’t wait for your ex to handle it.

The notice should identify the qualifying event, the date it occurred, and the names of everyone seeking coverage. The Summary Plan Description for your ex’s plan sets out the required format and delivery method. Send it a way that creates a record, whether certified mail or email with a read receipt, because a later dispute about whether you met the deadline is much easier to win with proof in hand.

After the administrator receives your notice, they have 14 days to send each qualified beneficiary an official election notice explaining COBRA rights and enrollment steps.⁵

Electing Coverage and Making the First Payment

Once you receive the election notice, you have 60 days to decide whether to elect COBRA, measured from the later of the qualifying event date or the date the notice was actually provided.⁴ Return the signed forms through whatever secure method the plan requires.

Your first premium is due within 45 days after you elect.⁴ That first payment covers everything from the divorce date through the current month, which can be a large lump sum if weeks have passed. Miss the 45-day window and the plan can terminate coverage.

Later premiums follow whatever schedule the plan sets, with a 30-day grace period for each payment. Pay outside the grace period and the plan can end your COBRA permanently.⁶

How Long the Coverage Lasts

Divorce and legal separation entitle you to a maximum of 36 months of continuation coverage, measured from the qualifying event.⁷ Your benefits stay identical to those of active employees, and any change the employer makes to the plan for its current workforce applies to you too.⁸

Coverage can end sooner if:

You don’t pay a premium within the grace period.
You become covered under another employer’s group health plan after electing COBRA.
You become entitled to Medicare after electing COBRA.
The employer stops offering any group health plan.
You engage in fraud or misconduct that would justify terminating any similar participant.

⁸

If the plan terminates you early, it must send a notice explaining the termination date, the reason, and any rights you have to seek other coverage.

What COBRA Costs

During your marriage, the employer likely paid most of the premium and your spouse’s paycheck covered the rest. Under COBRA you pay both portions plus a 2% administrative surcharge, for a total of 102% of the plan’s full cost.³

The average employer-sponsored family plan runs roughly $27,000 a year. At 102%, continuing family coverage after divorce would run about $2,295 per month. Individual coverage costs less, but even single-person plans often exceed $700 monthly at full price. Real numbers vary widely by employer, plan type, and region.

One thing that partially offsets the cost: because COBRA continues the same plan, any progress toward your annual deductible and out-of-pocket maximum carries over. Switching to a new plan resets that clock.

Tax Breaks That Reduce the Hit

If you have a Health Savings Account, you can use those funds tax-free to pay COBRA premiums. The IRS specifically lists health care continuation coverage as an approved HSA use, even though most other insurance premiums are not eligible.⁹

COBRA premiums also count as deductible medical expenses when you itemize, but only the amount that exceeds 7.5% of your adjusted gross income.¹⁰ Premiums alone rarely clear that threshold, but combined with other medical costs in a divorce year they sometimes can.

COBRA or the ACA Marketplace?

COBRA isn’t your only choice. Divorce triggers a 60-day special enrollment period on the ACA Health Insurance Marketplace, giving you access to plans outside the normal open enrollment window.¹¹ For many newly divorced spouses, a Marketplace plan with premium tax credits will cost far less than COBRA.

Premium tax credit eligibility depends on household income falling between 100% and 400% of the federal poverty level. For a single person in coverage year 2026, that range is roughly $15,650 to $62,600. You also can’t be eligible for affordable employer coverage or for programs like Medicaid or Medicare.¹²

Filing status matters. If you file as “married filing separately,” you generally cannot receive premium tax credits. The IRS makes an exception if you lived apart from your spouse for the last six months of the tax year, file a separate return, and maintain a home for a dependent child. Domestic abuse and spousal abandonment victims also qualify for relief.¹²

The decision usually comes down to math. Substantial subsidies can make Marketplace coverage a fraction of COBRA’s price. If you’ve already hit your deductible on the current plan for the year, COBRA preserves that. And if a new employer plan is a few months away, COBRA’s continuity can be worth the higher monthly cost for a short stretch.

If You’re Near Medicare Age, Read This First

Older divorced spouses need to be careful. If you’re eligible for Medicare and rely on COBRA instead, COBRA becomes secondary coverage and may pay only a small portion of your health care costs, leaving you responsible for most expenses.¹³

The bigger trap is the Part B enrollment deadline. You get 8 months after employer coverage ends to sign up for Part B without a penalty, and COBRA does not extend that window. Stay on COBRA for the full 36 months and you’ll have missed the Part B deadline by years, triggering a lifetime late-enrollment penalty on your Part B premium and a likely coverage gap until the next general enrollment period.¹³ If you’re 65 or approaching it, enroll in Medicare first and treat COBRA as supplemental at most.

If the Employer Is Too Small for Federal COBRA

Federal COBRA only reaches employers with 20 or more employees.¹ More than 40 states have their own continuation coverage laws, sometimes called “mini-COBRA,” that extend similar protections to smaller employers. Durations, deadlines, qualifying events, and premium rules vary by state. Check with your state insurance department or the plan administrator. The ACA Marketplace special enrollment period after divorce applies regardless of employer size, so that path stays open either way.

Getting COBRA Into the Divorce Agreement

Nothing in federal law requires your ex to pay your COBRA premiums, but a divorce settlement or court order can. Many agreements require the employee spouse to reimburse COBRA costs for a set period, especially where one spouse was financially dependent during the marriage. Courts in most states can factor health insurance costs into spousal support or property division.

If you’re still negotiating, push for specific language: a dollar amount, a percentage of the premium, or a defined period. A vague promise to “help with health insurance” is unenforceable. And remember that the plan administrator holds you responsible for timely premium payments regardless of what the decree says. If your ex misses a payment, the plan will terminate your coverage, and you’ll be enforcing the order in court while uninsured.
