Marriage and divorce both scramble your health insurance, but in opposite directions. Marriage usually gives you more options and a deadline to sort them out. Divorce takes options away and starts a clock. Here is how each one works.
Getting married: a special enrollment period
Marriage is a qualifying life event, which opens a special enrollment period. You generally have 60 days from the wedding date to enroll in or change a marketplace plan, join your spouse’s employer plan, or combine onto one plan. At least one spouse must have had coverage before the marriage in most cases, so do not let both policies lapse in the months before the wedding.
You have three basic choices. One spouse joins the other’s employer plan. You each keep your own coverage. Or you shop the marketplace together as a household. The right answer depends on the numbers: compare the cost of adding a spouse to an employer plan against two marketplace premiums with your combined income. Combining incomes can change your subsidy, sometimes for the better and sometimes pushing you over a threshold, so rerun the numbers as a household rather than assuming last year’s setup still works.
After the wedding: update everything
A new spouse changes your tax household, and marketplace subsidies follow the tax household. Update your marketplace application with the marriage, the combined income, and the new household size. If you do not, the premium tax credit keeps paying out on stale information, and the IRS reconciles the difference at tax time. This is also the moment to check beneficiaries, emergency contacts, and whether a family deductible now makes more sense than two individual ones. Our guide to embedded vs aggregate family deductibles explains that tradeoff.
Getting divorced: coverage ends for the ex-spouse
Divorce ends a spouse’s eligibility under the other spouse’s plan. The divorce itself is a qualifying life event, so the spouse losing coverage gets a 60-day special enrollment period to buy a marketplace plan or join their own employer’s plan. Do not wait for the divorce to be final to start shopping; the enrollment window runs from the date coverage is lost, and a gap month with no insurance is exactly when something expensive happens.
COBRA is the bridge most people hear about first. It lets the divorced spouse stay on the ex’s employer plan for up to 36 months after divorce, but at the full premium plus a 2% fee. That is often double or triple what the employee was paying. It makes sense as a short bridge if you are mid-treatment with specific doctors, but for most people the marketplace is cheaper. Our COBRA vs marketplace vs Medicaid comparison runs the numbers.
Children after divorce
Children can usually stay on either parent’s plan regardless of custody, but only one parent’s plan should cover them to avoid coordination-of-benefits headaches. The divorce decree sometimes specifies who provides coverage. If neither parent has affordable coverage, check CHIP, which covers kids in families with incomes too high for Medicaid. A change in the child’s coverage situation can also trigger its own enrollment options, so treat the child’s coverage as a separate decision from the adults’.
The paperwork both situations share
Report the change to the marketplace within 30 days, even though the enrollment window is 60. The 30-day reporting keeps your subsidy accurate; the 60-day window is your deadline to pick a plan. Keep the marriage certificate or divorce decree handy, because the marketplace may ask for proof of the qualifying event. And if employer coverage is in the mix, loop in HR early. Employer plan changes after marriage or divorce have their own deadlines, often 30 days, which can be shorter than the marketplace window.
Marriage and divorce are already expensive and stressful. The insurance part is manageable if you treat it as a deadline-driven task: figure out the qualifying event date, count forward 60 days, and do the household math before you pick. Our qualifying life events guide covers the other events that open the same window.
