Protecting assets when a spouse has dementia requires acting quickly and deliberately, ideally before cognitive decline reaches the point where legal documents can no longer be signed. The most effective tools are a durable power of attorney, a revocable living trust, and Medicaid planning strategies such as spousal impoverishment protections — which allow the healthy spouse, called the community spouse, to retain a portion of marital assets while the ill spouse qualifies for long-term care coverage. For example, a couple in Ohio with $180,000 in savings may be able to structure their finances so the healthy spouse keeps roughly $90,000 under federal Medicaid rules, rather than spending nearly everything on nursing home costs before coverage kicks in.
This article covers the legal documents you need, how Medicaid spousal protection rules work, what to do if planning starts late, and the mistakes that put assets most at risk. Time is the central variable in dementia asset protection. The earlier a family consults an elder law attorney — even at the first signs of cognitive impairment — the more options are available. Once a person lacks the mental capacity to understand and sign legal documents, the family is left pursuing guardianship or conservatorship through the courts, a slower and more expensive process that limits flexibility.

What Legal Documents Protect a Spouse’s Assets When Dementia Is Diagnosed?
The most critical document is a durable power of attorney (DPOA), which grants a named agent — typically the healthy spouse or an adult child — authority to manage financial affairs if the ill spouse becomes incapacitated. Unlike a standard power of attorney, the durable version remains valid after the principal loses mental capacity, which is precisely the scenario families face with dementia. Without it, no one has legal authority to sell property, access bank accounts, or make investment decisions on behalf of the person with dementia. A healthcare proxy or healthcare power of attorney is equally important, designating who makes medical decisions when the ill spouse cannot.
Paired with an advance directive or living will, these documents ensure the healthy spouse or another trusted person can coordinate care without court intervention. Some families also add a HIPAA release so medical providers can share information freely with caregivers. A revocable living trust can be a powerful complement to the DPOA. When assets are held in a trust, the successor trustee — named in the trust document — can manage those assets without probate and with greater flexibility than a POA alone allows. For a couple where one spouse is recently diagnosed, retitling real estate and investment accounts into a joint revocable trust while the diagnosed spouse still has legal capacity can simplify asset management considerably.
How Do Medicaid Spousal Impoverishment Rules Help Protect the Healthy Spouse?
Federal Medicaid law includes spousal impoverishment protections specifically designed to prevent the community spouse from becoming destitute while the ill spouse receives nursing home care. Under these rules, the healthy spouse is entitled to keep a minimum monthly maintenance needs allowance (MMMNA) from the couple’s combined income — in 2024, this floor is approximately $2,465 per month, with states setting the ceiling higher in some cases. The healthy spouse is also entitled to a community spouse resource allowance (CSRA), which in most states allows them to retain between roughly $30,828 and $154,140 in countable assets (figures adjust annually). These protections mean that a couple does not have to spend down to near zero before Medicaid eligibility begins.
In practice, an elder law attorney can perform a Medicaid asset assessment to determine exactly what the couple owns, what is countable versus exempt, and how much the community spouse is permitted to keep. Exempt assets typically include the primary residence (as long as the community spouse lives there), one vehicle, household furnishings, and certain prepaid burial plans. However, these rules apply to long-term care Medicaid, not to all Medicaid programs. If the ill spouse needs only home-based care, the rules and thresholds differ by state and may be more restrictive. A family assuming nursing home Medicaid rules apply to in-home waiver programs may miscalculate what they’re allowed to keep — and face a penalty period or coverage denial as a result.
What Is Medicaid Planning and Is It Legal?
Medicaid planning refers to legal strategies used to structure assets and income so a person qualifies for Medicaid without unnecessary spend-down. common approaches include converting countable assets into exempt ones — for instance, paying off a mortgage on the primary home, purchasing a newer vehicle, or making home modifications — because these conversions reduce countable assets without violating Medicaid rules. Another strategy is purchasing a Medicaid-compliant annuity, which converts a lump sum into a stream of income for the community spouse, effectively reducing the countable asset pool. There is often confusion about whether Medicaid planning is legal. It is, provided it follows state and federal guidelines.
The key restriction is the five-year lookback period: Medicaid reviewers examine all asset transfers made within the 60 months before application. Gifts to children, transfers to family trusts at below-market value, or other asset movements made within that window can trigger a penalty period during which Medicaid will not pay for care. Consider a family where a father with Alzheimer’s requires memory care and the couple had gifted $60,000 to their children two years earlier. Even though the gift was made with good intentions, it falls within the lookback window and could result in several months of ineligibility — during which the family would be responsible for the full cost of care. An elder law attorney can help calculate the penalty and advise whether any exceptions apply.
Should the Healthy Spouse Consider a Postnuptial Agreement or Divorce?
In states with community property laws or in situations where one spouse has significant individual debt from medical bills, some families explore postnuptial agreements to clarify which assets belong to which spouse. This can protect the healthy spouse’s retirement accounts or inheritance from being counted in a Medicaid spend-down. However, postnuptial agreements in the context of Medicaid planning receive scrutiny, and their effectiveness varies significantly by state. More controversially, some elder law attorneys discuss “Medicaid divorce” — legally separating from a spouse specifically to protect assets under individual rather than marital ownership rules.
While this strategy has been used successfully in certain states, it carries profound emotional, ethical, and legal risks. The healthy spouse gives up inheritance rights, Social Security spousal benefits, and may be required to pay alimony, which counts as income to the ill spouse and can complicate Medicaid eligibility. It is a last resort measure, not a planning tool, and should only be considered after exhaustive review by an attorney who specializes exclusively in elder law. The simpler alternative for most couples is proper asset titling and trust planning. Keeping the healthy spouse’s retirement accounts in their own name — since IRAs owned by the community spouse are often exempt or protected under state rules — and converting joint assets into exempt categories is usually far less disruptive and achieves comparable protection.
What Happens If Legal Planning Was Delayed Too Long?
If dementia has progressed to the point where the ill spouse can no longer sign legal documents, the family loses access to the fastest and most flexible planning tools. In that case, the healthy spouse or an adult child may need to petition a court for guardianship (over personal and medical decisions) or conservatorship (over financial decisions). This process typically involves a physician’s evaluation, a court hearing, legal fees, and ongoing court oversight of financial decisions — all of which add time and cost. One important but underused option in late-stage situations is a court-authorized spousal refusal. In some states, particularly New York, the community spouse can formally refuse to contribute their assets toward the cost of the ill spouse’s care.
The state may then pursue the community spouse for reimbursement, but in practice these cases are rarely litigated aggressively, and in the meantime Medicaid coverage can begin. This is a state-specific and legally sensitive strategy, not available everywhere. A warning: some families, facing the urgency of a late diagnosis, turn to financial advisors rather than attorneys. Financial advisors are not trained in Medicaid law and cannot draft legal documents. Acting on financial advice alone in a crisis situation has led families to make transfers or purchase products that trigger Medicaid penalties rather than prevent them. The right professional in this situation is an elder law attorney, not a financial planner, insurance agent, or general estate planning attorney.
How Does Long-Term Care Insurance Factor In?
If the ill spouse has a long-term care insurance policy in force, it becomes one of the most valuable assets in the planning picture. Benefits from a qualifying long-term care policy can pay for memory care facility costs, in-home care, or adult day programs, reducing or delaying the need to spend down other assets and postponing any Medicaid application.
A couple where the ill spouse has a $200-per-day benefit with a three-year benefit period effectively has a pool of over $200,000 to apply toward care costs, which dramatically changes the asset protection math. If neither spouse has long-term care insurance and the healthy spouse is still insurable, purchasing a policy for the healthy spouse protects future assets if that spouse also eventually needs care. Purchasing coverage for the already-diagnosed spouse is generally no longer possible once dementia has been documented, as most policies exclude pre-existing cognitive impairment.
Planning for the Healthy Spouse’s Future Security
Asset protection planning cannot focus exclusively on qualifying the ill spouse for Medicaid. The healthy spouse’s long-term financial and physical wellbeing must be central to the plan. Caregiver burnout is common, and the healthy spouse may face their own health challenges and care needs within years of the ill spouse’s diagnosis.
Any plan that depletes the healthy spouse’s retirement savings, forces them to sell the home, or leaves them with inadequate monthly income has failed, even if it technically achieved Medicaid eligibility. The best plans are built around the healthy spouse maintaining housing stability, income, and access to their own retirement funds, while using every legal tool available to minimize how much of the couple’s shared assets must be spent before public benefits begin. Elder law, estate planning, and financial planning intersect here, and the families who navigate this best tend to be those who assembled a small team — an elder law attorney, a fiduciary financial advisor, and the patient’s care manager — rather than relying on a single professional or trying to manage everything alone.
Conclusion
Protecting assets when a spouse has dementia is both a legal and a logistical challenge, but it is manageable with the right guidance and early action. The core tools — durable power of attorney, revocable trust, Medicaid spousal protection rules, and strategic asset conversion — can preserve financial stability for the healthy spouse without exposing the family to fraud or improper transfers. The five-year lookback period is real, penalties for missteps are significant, and the rules differ meaningfully by state, which is why working with a qualified elder law attorney is essential rather than optional.
If a diagnosis has already been made, the time to act is now. Even in late-stage situations, options like guardianship, conservatorship, and in some states spousal refusal can provide a path forward. The goal is not to hide assets or game the system — it is to use the legal protections Congress and state legislatures have built specifically to prevent healthy spouses from becoming financially devastated by the cost of long-term dementia care.
Frequently Asked Questions
Can I transfer assets to my children to protect them from being spent on dementia care?
Transfers to children within five years of a Medicaid application will trigger a penalty period during which Medicaid will not pay for care. In most cases, this strategy backfires unless it was done more than five years before any application is needed.
Is the family home protected from Medicaid if my spouse goes into a nursing home?
Yes, as long as the healthy spouse continues to live there, the home is generally exempt from Medicaid’s asset calculation. However, after the death of both spouses, the state may pursue Medicaid estate recovery against the home. An elder law attorney can explain what protections and exceptions apply in your state.
What is the difference between a durable power of attorney and guardianship?
A durable power of attorney is created voluntarily by the person while they still have legal capacity. Guardianship is a court-ordered appointment made after a person loses capacity. Guardianship is slower, more expensive, and subject to ongoing court oversight, which is why establishing a DPOA early is strongly preferred.
Does Medicare cover nursing home or memory care costs for someone with dementia?
Medicare covers short-term skilled nursing care following a qualifying hospital stay, but it does not cover long-term custodial care, which is what most dementia patients ultimately need. Long-term care is primarily funded through private pay, long-term care insurance, or Medicaid.
Can a spouse with mild dementia still sign legal documents?
Possibly. Legal capacity requires that the person understands the nature and effect of what they are signing, not that they have a perfect memory. A physician or attorney can assess whether capacity exists. Acting while capacity remains is always preferable to waiting.
What is an elder law attorney and how do I find one?
Elder law attorneys specialize in legal issues affecting older adults, including Medicaid planning, guardianship, and estate planning for incapacity. The National Academy of Elder Law Attorneys (NAELA) maintains a directory at naela.org, and the Special Needs Alliance also provides referrals.
