Nobody wants to think about this stuff. Not the legal paperwork, not the money conversations, and definitely not the reason you’re reading this article in the first place — someone you love is losing cognitive ground, and the window for getting their affairs in order is shrinking.
But here’s the hard truth: estate planning decisions that feel overwhelming today become impossible tomorrow. If your parent or spouse has been diagnosed with mild cognitive impairment, early-stage Alzheimer’s, or any form of dementia, this is the most time-sensitive item on your list. Not medications. Not memory care research. This.

Because once a person lacks the legal capacity to understand and sign documents, the options narrow dramatically — and the ones that remain are expensive, slow, and controlled by a court instead of your family.
This guide breaks down the three main ways assets transfer after death — wills, trusts, and named beneficiaries — and explains which ones matter most when cognitive decline is part of the picture. No legalese. No theoretical scenarios. Just the practical information families in this situation actually need.
Important: This article is educational content, not legal advice. Estate planning laws vary significantly by state. The information here provides a general framework, but your family’s situation requires guidance from a qualified elder law attorney in your state. Do not make legal decisions based solely on this or any other article.
The Three Paths Assets Take After Death
When someone dies, their assets don’t just automatically go to the right people. Every dollar, every piece of property, every bank account has to travel through one of three channels to reach whoever is supposed to receive it:
- Probate (via a will) — A court-supervised process that validates the will, pays debts, and distributes assets. Public, sometimes slow, potentially expensive.
- Trust distribution (via a trust) — Assets held in a trust pass directly to beneficiaries according to the trust’s terms. No court involvement. Private and usually faster.
- Beneficiary designation (via account paperwork) — Certain accounts — life insurance, retirement accounts, payable-on-death bank accounts — pass directly to whoever is named on the account. Bypasses both probate and trusts entirely.
Here’s what trips families up: most people need a combination of all three, not just one. A trust doesn’t cover assets that were never transferred into it. A will doesn’t override a beneficiary designation on a retirement account. And beneficiary designations only apply to specific account types — they can’t transfer a house or a car.
Understanding how these three mechanisms work together — and where they conflict — is the key to making sure your family’s assets end up where they’re supposed to go.
Wills: The Baseline Everyone Needs
What a Will Does (and Doesn’t Do)
A will is a legal document that says: “When I die, here’s who gets what, and here’s who I want in charge of making it happen.” It names an executor (the person who manages the process), specifies how assets should be distributed, and can name guardians for minor children.
What a will does NOT do: take effect while the person is alive. A will has zero authority during incapacity. If your parent has dementia and can no longer manage their finances, a will does nothing to help. You need a durable power of attorney for that.
The Probate Process
Every will goes through probate — a court-supervised process where a judge validates the will, the executor inventories assets, creditors get paid, and whatever remains gets distributed to beneficiaries.
How painful probate is depends heavily on your state:
- Timeline: Typically 6 months to 2 years. Contested estates can take much longer.
- Cost: Varies wildly. Some states (like California) set executor and attorney fees as a percentage of the estate — which can mean tens of thousands of dollars on a modest estate. Other states (like Texas) have relatively simple, inexpensive probate processes. Many states fall somewhere in between, with total costs typically running 2-7% of the estate’s value.
- Privacy: Probate is a public proceeding. The will, asset inventory, and distribution plan all become part of the public record. Anyone can look them up.
When a Will Is Sufficient
For some families, a straightforward will is enough. If the estate is relatively small, all property is in one state, beneficiary designations cover the major financial accounts, and the family dynamics are simple (no blended families, no estranged relatives likely to contest), probate may be manageable.
Several states also offer simplified or “small estate” probate procedures for estates below a certain threshold — ranging from $25,000 to $200,000 depending on the state.
The Dementia Problem with Wills
To create or modify a valid will, a person must have “testamentary capacity.” This means they must understand:
- The nature and extent of their property (what they own)
- Who their natural beneficiaries are (spouse, children, etc.)
- What the will does (that it distributes their assets after death)
- How these elements relate to each other
A person with mild cognitive impairment or early-stage dementia may still meet this standard. A person with moderate to severe dementia almost certainly does not. And if a will is signed by someone who lacked capacity, it can be challenged and potentially thrown out by a court — which means the estate gets distributed according to state intestacy laws (the default rules when there’s no valid will), not according to what the person actually wanted.
This contestability risk is one of the biggest reasons dementia families need to act fast.
Pour-Over Wills
A pour-over will is a special type of will designed to work alongside a trust. It acts as a safety net: any assets that weren’t transferred into the trust during the person’s lifetime get “poured over” into the trust at death. The assets still go through probate (because they’re passing through a will), but they ultimately end up distributed according to the trust’s terms.
Think of it as a catch-all. If your parent set up a trust but forgot to retitle the car or a small bank account, the pour-over will makes sure those stray assets still end up in the right place.
Trusts: When and Why They Matter
A trust is a legal arrangement where one person (the “grantor” or “settlor”) transfers assets to be managed by another person (the “trustee”) for the benefit of specified people (the “beneficiaries”). It sounds complicated, but in practice, a revocable living trust is one of the most practical tools a dementia family can have.
For a deeper walkthrough of setting one up, see our step-by-step guide: How to Set Up a Living Trust for Your Aging Parent.
Revocable vs. Irrevocable Trusts
Revocable living trust: The grantor keeps full control. They can change the terms, add or remove assets, change beneficiaries, or dissolve the trust entirely at any time while they have capacity. After death (or incapacity), the successor trustee takes over and distributes assets according to the trust’s instructions. This is the type most families create for basic estate planning.
Irrevocable trust: Once created, the grantor gives up control and ownership of the assets placed in it. The terms generally cannot be changed. This sounds extreme, and it is — but it serves a specific purpose we’ll get to in a moment (hint: Medicaid).
What Trusts Actually Protect Against
One of the most common misconceptions: a revocable living trust does NOT protect assets from creditors or lawsuits during the grantor’s lifetime. Because the grantor retains control, the law treats those assets as still belonging to them.
What a revocable trust DOES do:
- Avoids probate. Assets in the trust pass directly to beneficiaries without court involvement.
- Maintains privacy. Unlike a will (public record), trust terms remain private.
- Speeds up distribution. Beneficiaries can often receive assets within weeks rather than months or years.
- Handles multi-state property. If your parent owns real estate in multiple states, each state would require a separate probate proceeding with just a will. A trust avoids this entirely.
- Provides incapacity planning. This is the big one for dementia families.
The Incapacity Advantage — Why This Matters for Dementia Families
When a revocable living trust is properly set up and funded, it names a successor trustee — the person who steps in to manage the trust assets if the grantor becomes incapacitated. This means your family can continue paying bills, managing investments, selling property, and handling financial affairs WITHOUT going to court for a guardianship or conservatorship.
Compare that to what happens without a trust (and without a durable power of attorney): when a parent with dementia can no longer manage their finances, the family has to petition a court for guardianship or conservatorship. This process is public, expensive (attorney fees, court costs, ongoing reporting requirements), and takes control away from the family — a judge decides who gets appointed, and that person must report to the court regularly.
A funded trust with a successor trustee sidesteps all of that.
What It Costs
A basic revocable living trust typically costs between $1,500 and $5,000 when created by an elder law attorney, depending on complexity and your location. More complex trusts (irrevocable trusts, trusts with tax planning provisions, special needs trusts) can cost significantly more.
That sounds steep until you compare it to the cost of probate or guardianship proceedings, either of which can easily exceed $10,000 — and often much more.
The Biggest Mistake: The Unfunded Trust
Creating a trust is only half the job. The trust is just a document — an empty container — until assets are actually transferred into it. This process is called “funding” the trust, and it means retitling assets (real estate, bank accounts, brokerage accounts) so they’re owned by the trust rather than the individual.
An astonishing number of families pay an attorney to draft a beautiful trust document and then never fund it. The result: when the parent dies or becomes incapacitated, all those assets that were supposed to be in the trust are still in the parent’s personal name — which means they go through probate anyway. The trust was useless.
If your family is setting up a trust for a parent with cognitive decline, make sure the funding happens immediately — not “eventually.” The attorney’s office should help with this, and it’s worth verifying every major asset has been retitled.
Medicaid and Irrevocable Trusts — Critical for Dementia Families
Memory care is brutally expensive. The national median cost for a memory care facility runs approximately $5,000 to $7,000 per month, and many families eventually turn to Medicaid to help cover these costs.
Here’s where irrevocable trusts enter the picture. Medicaid has strict asset limits — in most states, an applicant can have no more than $2,000 in countable assets. Medicaid also has a “lookback period” — currently 60 months (5 years) in most states — during which the agency reviews all asset transfers. If you gave away or transferred assets during that window, Medicaid imposes a penalty period during which the applicant is ineligible for benefits.
An irrevocable trust, created and funded more than 5 years before the Medicaid application, can potentially shelter assets from Medicaid’s asset count. But the timing is critical: the 5-year clock starts when assets are transferred into the irrevocable trust, not when the trust document is signed.
This is why early planning matters so much for dementia families. If you wait until your parent needs memory care to start thinking about Medicaid, it’s probably too late for trust-based Medicaid planning. The 5-year lookback makes it impossible to protect assets at the last minute.
A strong warning: Medicaid planning with irrevocable trusts is complex, state-specific, and full of traps for the unwary. This is not a DIY project. An elder law attorney who specializes in Medicaid planning is essential. Done wrong, it can actually make your parent’s situation worse.
Named Beneficiaries: The Overlooked Shortcut
Beneficiary designations are the estate planning tool nobody thinks about — and they control more money than most families realize.
Which Accounts Allow Beneficiary Designations
- Life insurance policies
- 401(k) and 403(b) retirement accounts
- Traditional and Roth IRAs
- Pension plans
- Annuities
- Bank accounts (payable-on-death / POD designation)
- Brokerage accounts (transfer-on-death / TOD designation)
- Savings bonds
For many families, these accounts represent the majority of their financial assets. The 401(k), the IRA, the life insurance policy — together, they often dwarf the checking account and household goods that go through probate.
The Override Rule
This is the single most important thing to understand about beneficiary designations: they override everything else. They override a will. They override a trust. They override what the family “knows” the parent wanted.
If your father’s will says “everything goes equally to my three children” but his 401(k) beneficiary form still names his ex-wife from 20 years ago, the ex-wife gets the 401(k). The will has no authority over that account. The beneficiary designation on file with the plan administrator is the only thing that matters.
This catches families off guard constantly.
The Danger of Outdated Beneficiaries
When was the last time your parent reviewed their beneficiary designations? Most people fill out those forms when they open the account or start a job and never look at them again. Decades pass. Marriages, divorces, deaths, estrangements — life changes, but the beneficiary form stays the same.
Common problems:
- Ex-spouse still named as primary beneficiary
- Deceased beneficiary with no contingent beneficiary named (the account goes to the estate and through probate)
- Minor children named directly (creates legal complications — a court-appointed guardian or custodian may be required to manage the funds)
- One child named, others accidentally excluded
- Nobody named at all
Per Stirpes vs. Per Capita
When naming beneficiaries, you’ll usually see an option for “per stirpes” or “per capita” distribution. The difference matters:
- Per stirpes: If a beneficiary dies before the account holder, that beneficiary’s share passes to their children (the account holder’s grandchildren). This keeps the inheritance moving down the family line.
- Per capita: If a beneficiary dies before the account holder, their share gets divided among the remaining living beneficiaries. The deceased beneficiary’s children receive nothing.
Most estate planning attorneys recommend per stirpes for families, but the right choice depends on your family’s specific situation.
Naming a Trust as Beneficiary
Sometimes it makes sense to name the trust as the beneficiary of a retirement account instead of naming individuals. This can provide more control over how and when the money is distributed — useful if a beneficiary has creditor problems, is a minor, has special needs, or can’t manage money responsibly.
However, naming a trust as beneficiary of an IRA or 401(k) has significant tax implications. Under current rules (the SECURE Act), most non-spouse beneficiaries must withdraw the entire inherited IRA within 10 years. When a trust is the beneficiary, the tax treatment can become more complex and potentially less favorable. This is another situation where professional guidance is essential.
The Dementia Risk with Beneficiaries
If a parent with dementia can no longer update their beneficiary designations — because they lack the capacity to understand and authorize changes — whatever is currently on file stays. Old designations, even clearly outdated ones, will stand. A power of attorney may allow an agent to update beneficiaries in some cases, but this varies by institution and state law. Some financial institutions refuse to allow POA agents to change beneficiary designations.
This is why reviewing and updating beneficiary designations should be one of the first things you do when a parent receives a cognitive decline diagnosis — before capacity becomes an issue.

| Speed of distribution | Months to years | Weeks to months | Days to weeks |
The Dementia-Specific Urgency
Everything above assumes your parent still has the legal capacity to sign documents. For families dealing with cognitive decline, this is the section that matters most.
Legal Capacity Requirements
To sign a will, trust, power of attorney, or any other legal document, a person must have the mental capacity to understand what they’re doing. The specific standard varies slightly depending on the type of document and the state, but the core requirement is the same: the person must understand the nature of the document they’re signing, the extent of their assets, and who the natural objects of their bounty are (their family members and loved ones).
A dementia diagnosis alone does not automatically mean a person lacks capacity. The standard is capacity at the moment of signing, not a general assessment of cognitive health. Someone with early-stage Alzheimer’s may have good days and bad days — and on a good day, they may very well have sufficient capacity.
But there’s a gradient here that works against you:
- Mild cognitive impairment (MCI): Likely still has capacity. This is your best window for action.
- Early-stage dementia: May still have capacity, especially on good days. An attorney experienced with cognitive decline can assess this. Some attorneys will arrange for a physician’s capacity evaluation before the signing to create a contemporaneous record.
- Moderate dementia: Capacity is questionable at best. Documents signed at this stage are highly vulnerable to legal challenge.
- Severe dementia: Almost certainly lacks capacity. Signing documents at this stage is not legally valid in virtually any jurisdiction.
The “Lucid Interval” Question
Some states recognize the concept of a “lucid interval” — a period during which a person with a diagnosed cognitive condition temporarily regains sufficient mental clarity to execute legal documents. In theory, a will or trust signed during a lucid interval is valid.
In practice, relying on lucid intervals is legally risky. Any document signed under these circumstances is almost guaranteed to be challenged by a disgruntled heir, and proving that the person truly had capacity during that window is a difficult, fact-intensive battle. If lucid intervals are your plan, you’ve probably waited too long.
What Happens When You Wait Too Long
If a parent with dementia has no valid estate planning documents and can no longer sign them, the family’s only remaining option is usually court-appointed guardianship (sometimes called conservatorship, depending on the state). This means:
- Filing a petition with the court
- Attorney fees for the petitioner — and often a separate court-appointed attorney for the person with dementia
- A hearing where the person’s incapacity must be proven (often requiring medical testimony)
- A judge decides who gets appointed — and it may not be the family member you’d expect
- Ongoing court supervision, annual accountings, and reporting requirements
- The process is public record
- Total costs can easily reach $5,000 to $15,000 or more, with ongoing annual costs after that
Guardianship strips the person of their legal autonomy. A judge — a stranger — makes the decisions that a family member with a simple power of attorney or trust could have handled privately, quickly, and affordably.

What Most Families Actually Need
For a family dealing with a parent who has early cognitive decline, here’s the combination most elder law attorneys will recommend. This isn’t the only approach, and your family’s situation may call for different tools — but this covers the bases for the vast majority of families:
- Revocable living trust (funded) with a successor trustee designated. This handles incapacity management and avoids probate for the assets inside it. Make sure the trust is actually funded — assets retitled into the trust — not just created on paper.
- Pour-over will as a safety net. Catches any assets that weren’t transferred into the trust and directs them there after death. Those assets still go through probate, but they end up distributed according to the trust’s terms.
- Updated beneficiary designations on all retirement accounts, life insurance policies, and any POD/TOD accounts. Review every single one. Make sure they reflect current wishes and name contingent beneficiaries.
- Durable power of attorney for finances. This is separate from the trust and covers financial decisions and accounts that aren’t part of the trust. See our complete guide to power of attorney.
- Healthcare power of attorney (healthcare proxy) and advance directive (living will). These cover medical decisions if the person can’t make them — who decides, and what the person’s wishes are regarding life-sustaining treatment. These are separate from financial documents but equally urgent.
Do this now. Not next month. Not after the holidays. Not when things “settle down.” If your parent still has the capacity to understand and sign these documents, the time is today. Every week you wait is a week closer to the point where these options may no longer be available.

How to Find an Elder Law Attorney
Estate planning for a family dealing with cognitive decline is not the time for a general practice attorney or a DIY legal website. You need an elder law attorney — someone who specifically handles estate planning, Medicaid planning, guardianship, and the legal issues that come with aging and incapacity.
Where to Search
- National Academy of Elder Law Attorneys (NAELA): Their online directory at naela.org lets you search for certified elder law attorneys by location. NAELA members must meet experience and education requirements specific to elder law.
- Alzheimer’s Association: Your local chapter often maintains referral lists of attorneys experienced with dementia-related legal planning.
- State bar association: Most have lawyer referral services with elder law categories.
- Area Agency on Aging: Can provide local referrals for elder law attorneys.
What to Expect Cost-Wise
Most elder law attorneys charge either flat fees for specific documents (trust package, will, POA) or hourly rates. Initial consultations may be free or $100-$300. A full estate plan with a trust, pour-over will, POA, and healthcare directive typically runs $2,000 to $6,000 total, depending on complexity and location.
Questions to Ask at the First Consultation
- How much of your practice is dedicated to elder law?
- Do you have experience working with clients who have cognitive impairment?
- Can you assess my parent’s capacity, or will you need a physician’s evaluation?
- Do you handle Medicaid planning? (Not all elder law attorneys do.)
- What’s included in your flat fee — just drafting, or also funding the trust?
- How long will the process take from start to finished, signed documents?
Red Flags
- Pushing expensive products (annuities, investment products) as part of estate planning
- Guaranteeing specific Medicaid outcomes
- Not asking about your parent’s cognitive status
- Pressuring you to sign immediately without time to review documents
- No clear fee structure or unwillingness to provide a written engagement letter
- No malpractice insurance

Frequently Asked Questions
Can someone with dementia sign a will or trust?
Possibly, if they have sufficient capacity at the moment of signing. A dementia diagnosis does not automatically eliminate legal capacity. However, the later in the disease progression, the higher the risk that the document will be challenged and potentially invalidated. An elder law attorney can evaluate the situation, and many will arrange a contemporaneous physician’s capacity assessment to create a record that supports the document’s validity.
Is a trust worth it for a small estate?
It depends on your state’s probate process and your family’s specific needs. In states with expensive or slow probate (California being the most well-known example), a trust can save significant time and money even on a relatively modest estate. In states with streamlined probate or small-estate exemptions, the cost of setting up a trust may not be justified purely for probate avoidance. However, if incapacity planning is a concern — and for dementia families, it almost always is — a trust provides significant value regardless of estate size.
My parent already has moderate dementia. Is it too late?
It may be too late for your parent to sign new documents. An elder law attorney should assess the situation, but be prepared for the possibility that guardianship or conservatorship through the courts may be the only remaining option for managing your parent’s affairs. This is expensive and time-consuming, but it’s not the end of the world — it’s the legal system’s backup plan for exactly this situation. The important thing is to act now rather than waiting further.
Do I need a lawyer, or can I use LegalZoom or similar services?
For a young, healthy person with a straightforward estate, online legal services can handle basic wills adequately. For a family dealing with cognitive decline, an elder law attorney is strongly recommended. The capacity questions, the Medicaid planning considerations, the coordination between trusts and beneficiary designations, the state-specific rules — these are areas where generic document templates fall short. The cost of an attorney is a fraction of what you’ll spend if documents are done incorrectly and need to be litigated later.
What’s the difference between a healthcare proxy and a living will?
A healthcare proxy (healthcare power of attorney) names a person to make medical decisions on your parent’s behalf when they can no longer make them. A living will (advance directive) specifies the person’s wishes regarding specific medical treatments — particularly life-sustaining measures like ventilators, feeding tubes, and resuscitation. Most families need both. They work together: the living will states what the person wants, and the healthcare proxy names who speaks for them when they can’t speak for themselves.
The Bottom Line
Estate planning isn’t one thing. It’s a combination of wills, trusts, beneficiary designations, powers of attorney, and healthcare directives — each covering different assets, different situations, and different moments in time. No single tool does it all.
For families dealing with cognitive decline, the stakes are higher and the timeline is shorter. Every one of these documents requires the person to have mental capacity to sign. Once that capacity is gone, the opportunity is gone with it — and what replaces it (court-appointed guardianship) is slower, costlier, more public, and less flexible than what you could have set up with an afternoon at an elder law attorney’s office.
If your parent has been diagnosed with any form of cognitive impairment, make an appointment with an elder law attorney this week. Not to panic. Not to rush. But to have an honest conversation about what’s in place, what’s missing, and what your family needs to do before the window closes.
The peace of mind — knowing that your parent’s wishes will be honored and their assets will go where they intended — is worth every dollar and every uncomfortable conversation.
