Divorce is one of the most disruptive financial events a person can go through. Health insurance often gets lost in the chaos of asset division, custody agreements, and legal fees, and the consequences of a coverage gap can be enormous. The good news: the law gives you multiple options and a meaningful enrollment window to land in a plan.
This guide covers the 60-day SEP deadline, the divorce-specific 36-month COBRA provision, how your subsidy changes when your household size shrinks to one, and what happens to your children's coverage when custody is split. If your income after divorce drops low enough, you may qualify for Medicaid with no income. If you are moving to a new state as part of the divorce, that move triggers a separate SEP on top of the divorce SEP.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
The most expensive mistakes people make after losing coverage in a divorce:
- Failing to notify the plan administrator of the divorce within 60 days. This single omission forfeits your 36-month COBRA right entirely. Submit written notice to your ex-spouse's HR department immediately after the decree is finalized.
- Counting the divorce decree date as the coverage loss date. These are often different. Coverage may end the last day of the month of divorce, or immediately. The SEP 60-day clock runs from actual coverage termination, so confirm the exact date with the plan administrator.
- Applying for marketplace coverage with the old household size. After divorce, your household is typically just you (and children if you have custody). Using the old joint household income inflates your reported income and reduces your subsidy, or eliminates it entirely.
- Forgetting that child support is not income for ACA or Medicaid purposes. Under MAGI rules, child support received does not count as household income. Do not include it in your healthcare.gov application or you may lose subsidies you actually qualify for.
- Enrolling children only on the ex-spouse's COBRA plan without checking CHIP. CHIP covers children up to 200-300% FPL depending on your state, year-round, at little or no cost. In most cases CHIP is cheaper than COBRA continuation for children.
- Changing your name before updating your SSA record. Your marketplace account must match Social Security Administration records exactly. Apply for the name change at ssa.gov before submitting your healthcare.gov enrollment, or your application will stall in verification.
How divorce changes your ACA subsidy calculation
The ACA subsidy system is built around household size and income expressed as a percentage of the Federal Poverty Level. Divorce reshapes both dimensions at once. If you were in a dual-income household at 350% FPL and now have a single income at 180% FPL, your subsidy jumps dramatically. See who qualifies for an ACA subsidy to understand where your new income lands. If you gain custody of two children, your household becomes three, raising the income threshold for every subsidy tier.
The 2026 subsidy cliff returned on January 1, 2026 when the enhanced premium tax credits from the American Rescue Plan and Inflation Reduction Act expired. Subsidies now cut off hard at 400% FPL: $62,600 for a household of 1, $124,800 for a household of 4. If your new post-divorce income puts you just above that line, consider whether deductions can bring your MAGI below it.
Custodial parent vs. non-custodial parent: whose plan covers the children?
For ACA marketplace purposes, the custodial parent (the one the child lives with for more nights per year) claims dependent children in their household. This is true even if the non-custodial parent claims the child as a tax dependent. The IRS Form 8962 instructions and healthcare.gov both use the custody definition, not the tax dependency test, for household composition.
If a court order requires the non-custodial parent to provide health coverage, that court order is itself a qualifying event under most employer group health plans, triggering a special enrollment window. The non-custodial parent should present the court order to their HR department promptly. Waiting until the next open enrollment is a common and costly mistake.
Frequently Asked Questions
Does divorce automatically trigger a Special Enrollment Period?
Not automatically. Divorce triggers a 60-day SEP only if you actually lose health coverage as a result. In most states using healthcare.gov, divorce alone without a coverage loss does not open an SEP. Confirm your coverage termination date with the plan administrator, then enroll at healthcare.gov within 60 days of that date.
How long is COBRA after divorce?
Divorce triggers a 36-month COBRA continuation period for the losing spouse and dependent children, not the 18 months workers get when they leave a job. This is one of the longest COBRA windows available under ERISA. You must notify your ex-spouse's plan administrator in writing within 60 days of the divorce decree to preserve this right.
Does my household size change for ACA subsidies after divorce?
Yes. Your ACA household is now just you, or you plus your children if you have primary custody. A smaller household with lower income typically means larger subsidies. Log in to healthcare.gov and start a new application with your updated household composition and projected 2026 income. Do not use the old joint household numbers.
Does child support count as income for ACA subsidies or Medicaid?
No. Under MAGI rules, child support received is not counted as household income for ACA premium tax credit or Medicaid eligibility purposes. Alimony from divorces finalized before January 1, 2019 IS counted as income. Alimony from post-2018 divorces is NOT. Enter the correct figures in your healthcare.gov application to avoid over-reporting income.
What happens to my children's health insurance after divorce?
Children lose coverage under a parent's employer plan when they are dropped as dependents. The custodial parent typically enrolls them on a new marketplace plan or CHIP. CHIP covers children up to age 19 at incomes from 200% to 300% FPL depending on your state, with very low or zero premiums. If a court order requires the non-custodial parent to cover the children, that order is a qualifying event for most employer plans.
Can I stay on my ex-spouse's health insurance after divorce?
No. Federal law requires employers to remove an ex-spouse from group health coverage once a divorce is finalized. You cannot remain on the plan as a dependent. COBRA allows you to continue the same coverage for up to 36 months at your own cost (102% of the full group premium), but you must elect it within 60 days of the divorce.
What if I miss the 60-day SEP after divorce?
If you miss the 60-day Special Enrollment Period, you will likely need to wait until ACA Open Enrollment in November 2026 for 2027 marketplace coverage. Medicaid has no deadline and you can apply year-round at any income level. Check whether another qualifying event (new job, move to a new state, income drop) opens a new SEP before November.
I am changing my name after divorce. Does that affect my health insurance enrollment?
Yes. Your healthcare.gov account must exactly match your Social Security Administration record. Update your legal name with SSA at ssa.gov first. Bring your divorce decree to a local Social Security office or mail a certified copy. Then update your marketplace account. Skipping this step causes application errors that can delay your coverage start date.
