Same-Sex Spouse or Partner Benefits Denied? Your Rights Under Federal Law

Since the Supreme Court's 2015 decision in Obergefell v. Hodges, same-sex marriage has been the law of the land — and with it, same-sex spouses have the right to the same employer-sponsored health benefits as any other married couple. Yet denials of same-sex partner and spousal benefits still occur, from administrative errors to deliberate discrimination.

This guide explains your rights under federal and state law and how to fight back when benefits are wrongfully denied.

Federal Rights for Same-Sex Spouses

Obergefell v. Hodges (2015): This Supreme Court ruling requires states to license and recognize same-sex marriages. It means that same-sex spouses are legally equivalent to opposite-sex spouses for all legal purposes, including employer benefits.

ERISA and employer benefits: Under ERISA, employer-sponsored health plans must extend coverage to spouses of eligible employees. Following Obergefell, the Department of Labor confirmed that "spouse" includes same-sex spouses in all ERISA-covered plans nationwide.

The Windsor case (2013): United States v. Windsor struck down DOMA's limitation on federal recognition of same-sex marriages, paving the way for Obergefell and establishing that same-sex marriages are recognized for federal benefit purposes.

ACA marketplace plans: Marketplace plans must allow spouses — including same-sex spouses — to enroll during open enrollment or through a qualifying life event (such as marriage, which is a Special Enrollment Period trigger).

Medicaid and federal programs: Following Obergefell, same-sex spouses are recognized for all federal benefit programs, including Medicaid spousal protections.

Domestic Partner Benefits: A More Complex Picture

Not all employers offer domestic partner benefits. Federal law does not require employer health plans to cover domestic partners (as opposed to legal spouses). However:

• Many states require domestic partner benefits for insurers regulated in that state
• Many large employers voluntarily offer domestic partner benefits
• States including California, New York, and Oregon have state laws extending benefit protections to domestic partners

If your employer does not offer domestic partner benefits and you are not legally married, federal law may not compel them to do so — but state law might.

Tax treatment of domestic partner benefits: When an employer covers a domestic partner, the IRS treats the employer contribution as taxable income to the employee (unlike spousal coverage, which is tax-free). This creates a financial disparity. If you're in this situation, ask your employer's HR team about imputed income and whether they offer any offset.

Common Denial Scenarios

Enrollment denial at time of marriage: An employee marries their same-sex partner and attempts to add them during the special enrollment period triggered by the marriage. The HR system or plan administrator rejects the enrollment. This is a direct violation of federal law and ERISA.

Documentation requirements exceeding legal requirements: Some plans require additional documentation from same-sex spouses that is not required from opposite-sex spouses — for example, requiring additional proof of marriage or proof that the marriage predates a specific date. Requiring different documentation for same-sex spouses is discriminatory.

Retroactive denial after a plan audit: Some plans audit dependent eligibility. If a plan questions whether a same-sex spouse qualifies as a legal dependent and conducts an audit, they must apply the same standards they apply to opposite-sex spouses.

Religious exemption claims: Some employers (typically religiously affiliated organizations) claim religious exemptions from covering same-sex spouses. The legal status of these exemptions is contested and varies by state and the type of employer. Consult a civil rights attorney if your employer claims a religious exemption.

Domestic partner claim denials: An employer offers domestic partner coverage, but when a claim is submitted under the domestic partner's coverage, the insurer denies it citing administrative issues, missing documentation, or eligibility questions.

How to Appeal a Benefit Denial

Step 1 — Request a written denial. Whether the denial was for enrollment or a specific claim, get the reason in writing.

Step 2 — Review your plan documents. The Summary Plan Description should define "spouse" and "dependent." After Obergefell, any definition that excludes same-sex spouses is legally unenforceable.

Step 3 — Escalate to HR first. Many same-sex spouse benefit denials stem from administrative errors or outdated systems. Your HR department may be able to correct the enrollment directly.

Step 4 — File an internal ERISA appeal. If HR cannot resolve it, file a formal written appeal through the plan's appeals process. Your appeal should:

• Reference Obergefell v. Hodges and the ERISA obligation to cover spouses
• Include a copy of your marriage certificate
• Cite the Department of Labor's guidance on same-sex spouses in ERISA plans

Step 5 — File a complaint with the Department of Labor. The Employee Benefits Security Administration (EBSA) at the DOL enforces ERISA and can investigate wrongful denials of same-sex spouse benefits. File at dol.gov/agencies/ebsa/workers-and-families/file-a-claim.

Step 6 — File a state civil rights complaint. Many states have civil rights agencies that investigate discrimination in employee benefits. File with your state's Department of Human Rights or Civil Rights Division.

Step 7 — Consult an employment attorney. Wrongful denial of same-sex spousal benefits may give rise to claims under federal law (including Title VII after Bostock), ERISA, and state civil rights statutes.

What About COBRA?

Same-sex spouses have the same COBRA continuation rights as opposite-sex spouses. If your spouse loses their job or other qualifying events occur, you can continue coverage under COBRA on the same terms as any other dependent.
