Estate Planning for LGBTQ+ Couples: Survivor Benefits With and Without Legal Marriage

Legal marriage has been available to same-sex couples nationwide since the 2015 Obergefell decision, but many longtime LGBTQ+ couples have not married and still have not decided whether to. The financial differences between married and unmarried couples are significant in old age. Social Security spousal and survivor benefits, retirement account rollover rules, inheritance taxes, real estate transfer rules, and end-of-life decision authority all change based on legal marital status. This guide walks through the main differences so you can make an informed choice. And it covers the additional issues that transgender seniors face when ID documents from before transition surface during estate administration.

Social Security is the single largest financial difference. A surviving spouse can claim the higher of their own benefit or 100 percent of the deceased spouse's benefit. For a couple where one partner earned a lot more, this difference can be hundreds of dollars per month for the rest of the survivor's life. Unmarried partners get none of this. They cannot claim their partner's benefit even if they cohabited for 40 years. The Social Security Administration requires a legal marriage of at least nine months before the death (with limited exceptions) to qualify for survivor benefits.

Retirement accounts have similar rules. A spouse can roll over an inherited 401(k) or IRA into their own IRA and continue tax-deferred growth on the original schedule. A non-spouse beneficiary (which is what an unmarried partner is) must withdraw the entire account within 10 years under the 2019 SECURE Act, which can trigger major tax bills. Pension survivor benefits work the same way: married couples often have a Joint and Survivor option that pays the survivor a percentage of the pension for life. Unmarried partners cannot be designated as recipients of these survivor pensions in most plans.

Health insurance also changes. Medicare does not have a spousal coverage benefit (each person is enrolled individually based on their own work history), so this matters less than it used to. But premium support programs, Medicaid spend-down rules, and long-term care eligibility all treat spouses differently from unmarried partners. In many states, a Medicaid applicant must spend down personal assets before qualifying for nursing home coverage, but a community spouse can keep the house and a share of the assets. An unmarried partner gets no community spouse protection.

Real estate and inheritance are where unmarried couples sometimes do better. Married couples in some states owe transfer taxes when one spouse dies and the house transfers, while joint tenancy with right of survivorship (a form of ownership available to anyone) transfers free of probate to the surviving owner. Federal estate tax exemption is currently $13.99 million per person in 2026, so most couples are not affected, but state estate and inheritance taxes vary and can apply at lower thresholds.

Transgender seniors face additional issues. Social Security records, Medicare records, retirement account beneficiary forms, and life insurance policies may still list a pre-transition name or gender marker. Updating these records is straightforward but takes time and consistent effort, and any gap can create problems during estate administration. The Social Security Administration accepts updates with documentation. Medicare follows SSA records automatically once SSA is updated.
