Estate Planning for Families Affected by Dementia

By Mark Moss | June 22, 2026

When a loved one is diagnosed with dementia or Alzheimer’s, the first instinct is often to focus on medical care: finding the right doctors, exploring treatment options, understanding what lies ahead.

But there’s another conversation that needs to happen just as urgently: estate planning.

This isn’t about being morbid or giving up hope. It’s about making sure your loved one’s wishes are documented while they can still participate in decisions—and making sure your family has the legal authority to help when help is needed.

May is Mental Health Awareness Month, and it’s an important time to acknowledge that cognitive decline affects millions of families. Here’s what you need to know about estate planning when dementia is part of your reality.

Why Timing Matters More Than Anything

In estate planning, there’s a concept called “legal capacity.” To sign legal documents like a will, trust, or power of attorney, a person must understand what they’re signing and the consequences of their decisions.

Dementia is progressive. Early in the disease, your loved one may still have the capacity to execute legal documents. But as the condition advances, that window closes—sometimes suddenly, sometimes gradually.

If legal documents aren’t in place before capacity is lost, your family may be forced to pursue guardianship, a court process that takes time, costs money, and results in a judge (not your loved one) deciding who makes decisions.

The message is clear: don’t wait. If your loved one has received a dementia diagnosis, estate planning should happen as soon as possible.

Essential Documents for Families Affected by Dementia

A comprehensive estate plan for someone with dementia should include:

Durable Power of Attorney. This allows a trusted person to manage finances, pay bills, access accounts, and handle legal matters. The word “durable” is critical. It means the power continues even after incapacity.

Health Care Surrogate Designation. This names someone to make medical decisions when your loved one cannot. It’s essential for navigating hospitalizations, treatment decisions, and long-term care.

Living Will. This documents end-of-life preferences, whether your loved one wants life-prolonging treatment, pain management preferences, and other critical choices. This spares family members from having to guess.

HIPAA Authorization. This allows designated family members to access medical records and communicate with healthcare providers, essential for coordinating care across multiple doctors.

Last Will and Testament or Revocable Living Trust. These documents ensure assets are distributed according to your loved one’s wishes. A trust can be particularly valuable because it allows for management of assets during incapacity, not just after death.

Planning for Long-Term Care Costs

Dementia care is expensive. According to the Florida Health Care Association, a private room in a Florida nursing home costs over $100,000 per year. Memory care facilities can be even more. And most families dramatically underestimate how long care will be needed.

This is where strategic planning becomes essential:

Medicaid Planning. Medicaid can cover long-term care costs, but it has strict income and asset limits. Planning ahead (ideally before care is needed) can help protect assets while preserving eligibility.

Asset Protection Strategies. Tools like irrevocable trusts, Lady Bird deeds, and strategic gifting can help protect the family home and other assets from being depleted by care costs.

Veterans Benefits. If your loved one is a veteran or the spouse of a veteran, VA Aid and Attendance benefits may help cover care costs. These benefits have their own planning considerations that should be coordinated with your overall strategy.

What If Capacity Is Already Gone?

If your loved one no longer has the capacity to sign legal documents, your options become more limited, but they’re not gone entirely. You may need to pursue guardianship, which gives a court-appointed guardian the authority to make decisions.

Guardianship is a last resort. It’s expensive, time-consuming, and requires ongoing court supervision. But when it’s necessary, having an experienced attorney guide you through the process can minimize stress and ensure your loved one’s interests are protected.
