They Have Lived Together for 20 Years and Never Married. When He Needs a Nursing Home at 81, Medicaid Will Ignore Her $500,000, and She Will Get None of the Protections a Wife Gets

Roughly 20.3 million U.S. adults were living with an unmarried partner as of 2024, according to the National Center for Family and Marriage Research. Many of those couples have been together for decades, sharing mortgages, income streams, and retirement plans without ever signing a marriage license. After 20 years under one roof, an unmarried couple discovers that Medicaid treats them like strangers, and that cuts both ways. When the 81-year-old partner enters a nursing home, the state looks at resources he owns or can legally access, along with his income. Her $500,000 investment account, titled in her name alone, sits outside the eligibility math. That is the good news, and it’s the whole reason some longtime partners never walk down the aisle.

The bad news arrives right after approval. His pension flows almost entirely to the nursing home. She can’t claim a share of it under the spousal income rules, can’t receive protected transfers from him, and has no automatic shield against Medicaid’s estate claim on assets he owned. A legal spouse gets all three. She gets none.

Why Her $500,000 Stays Off His Medicaid Application

Nursing-home Medicaid, the long-term care program that pays when savings run out, examines resources owned by the applicant. (Medicare, the health insurance program for people 65 and older, only covers up to 100 days of skilled nursing after a hospital stay and never pays for custodial long-term care.) An unmarried partner’s separately titled account doesn’t become “available” just because the two of them shared a kitchen for two decades.

The cost pressure driving these decisions is real. According to CareScout’s 2025 Cost of Care Survey, the national median for a nursing home runs $9,581 a month for a semi-private room and $10,798 a month for a private room. At those rates, a multi-year stay can exhaust six-figure savings quickly, which is precisely why Medicaid eligibility rules matter so much.

Compare that to marriage. Medicaid initially counts resources owned by either spouse when an institutionalized spouse applies. Federal spousal-impoverishment rules then carve out a piece for the spouse still at home, called the Community Spouse Resource Allowance. In 2026, federal rules protect at least $32,532 and generally cap the standard allowance at $162,660. The couple’s actual allowance depends on their combined countable resources and the state’s rules.

The reversal is stark. Unmarried, her $500,000 generally stays out of his file. Married, that same account walks straight into the initial resource assessment, and only a slice comes back out as protected.

The Income Rule She Doesn’t Get: The $2,705 MMMNA

Once Medicaid approves the nursing-home stay, most of the resident’s monthly income becomes his patient-pay contribution to the facility, after limited deductions for a personal needs allowance and health insurance premiums.

A legal spouse with thin income of her own can claim part of the institutionalized spouse’s income through the Monthly Maintenance Needs Allowance. Effective July 1, 2026 through June 30, 2027, the federal minimum is $2,705 a month in 48 states and Washington, D.C. Qualifying shelter costs can push the standard allowance as high as $4,066.50. In unusual cases, a spouse can petition for a higher amount.

An unmarried partner gets zero. If his pension had been covering the mortgage, the property taxes, and the grocery bill for 20 years, Medicaid doesn’t preserve a dollar of it for her. The income she counted on simply stops.

Transfers, the House, and Estate Recovery

Federal law generally exempts transfers to a legal spouse, or for that spouse’s sole benefit, from the transfer penalty. Once eligibility is established, assets up to the community-spouse allowance can be placed in the spouse’s name and remain protected. An unmarried partner isn’t on the list. If he gifts her cash, his share of the house, or a car inside the five-year lookback, Medicaid can treat it as an uncompensated transfer and impose a penalty period during which it won’t pay for his care.

One line is worth keeping clear: Medicaid didn’t count assets that were already hers. It can absolutely scrutinize assets that were his and got moved into her name late.

If the deed is in her name alone, his Medicaid case generally has no hook into the house. If he owns all or part of it, marriage would delay estate recovery while she’s alive and block certain lifetime liens. She has no such automatic protection. Her right to stay may depend on the deed, state probate rules, a life estate, or a state hardship exception, and states differ sharply here. California, for example, still limits estate recovery to probate assets, while others pursue non-probate property such as jointly held homes. Most of these fights come down to a deed, a beneficiary form, or a titling choice made years earlier, which is exactly the checklist we put together in a free estate guide.

Marriage Isn’t an Obvious Fix

The temptation is to say they should have married. Marriage would have unlocked the MMMNA, exempt transfers, and estate-recovery protection. It also would have dragged her $500,000 into his initial resource assessment on day one.

Before an unmarried couple moves one partner into nursing care, the questions worth answering are basic and specific: who legally owns each account, whose name is on the deed, whose income pays which household bill, and what happens to the partner staying home when that income disappears. Medicaid respected the line they drew between their assets. It also enforced the legal divide that came with never marrying.
