She Married Him at 74 With a Prenup Protecting Her $600,000. When He Needed a Nursing Home at 80, Medicaid Told Her a Prenup Doesn’t Exist in Its Rules

A widow remarries at 74 with $600,000 in savings. She signs a prenuptial agreement keeping every dollar in her name for her children from her first marriage. Six years later, her second husband has advanced dementia and needs a nursing home. She hands the Medicaid caseworker the prenup. The caseworker hands it back. As far as Medicaid is concerned, that document does not exist.

This shock plays out in thousands of later-in-life marriages every year, and it is entirely predictable once you understand how federal Medicaid law is structured. A prenup is a private contract between two spouses. Medicaid is not a party to it. Federal law imposes a statutory spousal obligation that private parties cannot waive by contract, and that obligation drives the entire long-term care eligibility calculation. The names on the accounts and the language in the prenup do not change the answer. As elder law attorney Antoinette Bone has explained, Medicaid adds both spouses’ assets together and a prenuptial agreement does not change that.

Why Medicaid Ignores the Prenup at the Resource Assessment

When one spouse enters a nursing home and applies for Medicaid long-term care coverage, the state performs a resource assessment: a snapshot of everything the couple owns on the day the ill spouse is institutionalized.

At that assessment, Medicaid combines the couple’s countable resources (bank accounts, brokerage accounts, CDs, and most investment property) regardless of whose name is on them and regardless of what any private agreement says. Her $600,000 and his $40,000 checking account are pooled together. The prenup does not carve her money out of that calculation.

Income works differently. Income follows the name on the check: his Social Security is his, her pension is hers. Resources get combined; income does not. That distinction trips up more couples than almost any other Medicaid rule.

What the Prenup Still Does

The prenup is not worthless outside the Medicaid context. It still governs what happens on divorce and at death. It can direct that her assets pass to her children rather than to her surviving husband’s estate, and in some states it affects exposure to estate recovery, the process by which Medicaid seeks to recoup what it paid by making a claim against the deceased recipient’s estate. Estate recovery rules vary sharply by state, and an elder law attorney practicing in the specific state has to answer that question.

What Actually Protects the Healthy Spouse

The protections that keep the at-home spouse (the community spouse, in Medicaid’s language) from being wiped out are statutory, not contractual. The Community Spouse Resource Allowance lets the community spouse keep a share of the couple’s combined countable resources up to a federal maximum that adjusts every January 1. For 2026, that ceiling is $162,660 (up from $157,920 in 2025), with a federal floor of $32,532. The specific amount a spouse can keep depends on how much the couple owns together and on the state they live in, since states may set any figure within the federal range.

The Minimum Monthly Maintenance Needs Allowance adds another layer of protection for income. If the community spouse’s own monthly income falls below a federally set floor, the institutionalized spouse’s income is diverted to close the gap before the nursing home gets paid. As of July 1, 2026, that floor is $2,705 per month in most states. It can rise as high as $4,066.50 per month when the community spouse’s housing costs are high enough to justify an upward adjustment.

It is worth noting a distinction that matters for some couples. The core nursing-home spousal protections have been permanent federal law since the Medicare Catastrophic Coverage Act of 1988. A separate provision extended those same protections to spouses of people receiving home and community-based services (HCBS), but that extension is set to expire on September 30, 2027, unless Congress acts. Advocacy groups have urged Congress to make the HCBS extension permanent, and legislation to do so has been introduced but had not passed as of late 2026. The statutory allowances described above remain the actual financial firewall for nursing home couples, not the prenup.

Tools That Genuinely Work in a Second Marriage

Elder law attorneys point to a short list when a later-in-life couple wants to protect one spouse’s premarital assets for children from a prior marriage:

• Irrevocable trusts funded well outside the five-year Medicaid lookback. Rules are complex and vary state to state, and the trust must be genuinely irrevocable.
• Medicaid-compliant annuities that convert a countable lump sum into an income stream for the community spouse, removing the funds from the asset calculation.
• Spousal refusal, available only in a minority of states (notably New York and Florida), lets the community spouse formally decline to contribute assets to the ill spouse’s care. It is grounded in federal law but actively practiced in only those two states.
• A prenup paired with actual asset segregation done years before either spouse needs care. The paper alone does nothing; retitling and time do the work.

Hard Truth About Whom the Law Protects

Medicaid’s spousal protections exist to keep the healthy spouse from destitution. They do not exist to preserve an inheritance for children from a prior marriage. A couple that marries at 74 with children from earlier relationships on both sides has to accept that gap and plan around it. The alternative is accepting that care costs may consume assets the prenup told everyone were safe.

The time to have this conversation is before the wedding, not after a diagnosis. Once one spouse has a dementia workup on the calendar, the lookback clock is already running, and the menu of options shrinks fast.

Editor’s note: This pass added the increase in the 2026 Community Spouse Resource Allowance ceiling from $157,920 in 2025 to $162,660, clarified that the MMMNA floor of $2,705 per month took effect July 1, 2026, and distinguished between the permanent federal nursing-home spousal protections (in place since 1988) and the separate HCBS extension that is scheduled to sunset September 30, 2027 unless Congress renews it.
