Power of Attorney (POA) for an Elderly Parent with Dementia
When your aging parent begins showing signs of dementia, it can be a confusing and emotional time. You might notice bills going unpaid, doctor appointments missed, or confusion around medications. One of the most powerful tools you can use to protect your parent and their future is establishing Power of Attorney (POA). But timing is critical.
Quick Answer: To get power of attorney for a parent with dementia, you must act while they still have legal capacity. A durable POA is typically the best choice. The process includes choosing a trustworthy agent, working with an elder law attorney, and finalizing the documents before your parent’s condition worsens.
This guide walks you through everything you need to know about setting up POA for a loved one with dementia—before it’s too late.
What Is Power of Attorney (POA)?
Power of Attorney is a legal document that gives someone (the “agent” or “attorney-in-fact”) the authority to make decisions on behalf of another person (the “principal”). This can include managing finances, handling legal matters, and making healthcare decisions.
There are different types:
- Financial POA – Handles money, bills, property, and banking
- Healthcare POA – Makes medical decisions if your parent can’t
- Durable POA – Remains in effect even after the person becomes incapacitated
- Springing POA – Only takes effect after a specific event, like a dementia diagnosis

Can You Get Power of Attorney If a Parent Has Dementia?
Dementia affects memory, reasoning, and judgment—making it harder (or eventually impossible) for your parent to handle day-to-day tasks. Without a POA in place, families may be unable to:
- Access bank accounts
- Pay bills or manage pensions
- Make time-sensitive medical decisions
In those cases, the only option may be court-appointed guardianship, which is expensive, time-consuming, and emotionally draining.

Steps to Get Power of Attorney for a Parent With Dementia
The key requirement to establish POA is mental capacity. Your parent must understand:
- What a POA is
- What powers they’re giving to someone else
- The consequences of signing
If your parent is in the early stages of dementia, now is the ideal time to act. You may want to have their doctor evaluate and document their decision-making ability.
In most dementia cases, a Durable POA is the safest choice. It stays in effect even as cognitive function declines. While a Springing POA may seem appealing, it can delay critical decisions if activation depends on formal diagnosis.
You’ll also need to decide who will serve as the agent. Choose someone who is:
- Trustworthy and organized
- Emotionally equipped to handle decisions
- Willing to act in the parent’s best interest
How to Set Up Power of Attorney
- Start the Conversation: Choose a calm, respectful time to talk with your parent. Emphasize that this is about protecting them, not taking control.
- Select the Right Agent: This may be an adult child, sibling, or trusted friend. Consider naming a backup (alternate agent) too.
- Consult an Elder Law Attorney: Each state has its own POA requirements. An attorney ensures the document is legally sound and properly executed.
- Prepare Documents: Include both financial and healthcare POAs. You may also need:
- HIPAA authorization form (to access medical records)
- Living will or advance directive
- Sign and Notarize: The POA must be signed while your parent is still legally competent. Many states also require notarization and witnesses.
- Distribute Copies: Share signed POAs with:
- Doctors
- Banks
- Insurance companies
- Other family members (as appropriate)

What If It’s Too Late?
If your parent no longer understands what a POA is or what it does, you’ll need to petition the court for guardianship (or conservatorship). This is a more invasive legal process, requiring medical testimony and judicial approval.
In such cases, it may help to learn about available legal resources for seniors or explore the difference between in-home care and other options.
Common Mistakes to Avoid
- Waiting too long: Once capacity is lost, your hands are tied.
- Not choosing the right agent: Pick someone trustworthy—not just someone nearby.
- Forgetting to update POAs: Major life changes (divorce, death) may require updates.
- Failing to share documents: A POA no one knows about can’t help in an emergency.
When to Seek Professional Help
If you’re unsure about the timing, legal steps, or family dynamics, it’s smart to consult:
- Elder law attorneys – for legally binding POA setup
- Medical professionals – to assess and document capacity
- Family mediators – if siblings disagree on next steps
You can also explore helpful topics like navigating family caregiving challenges to prepare for your caregiving role.
Final Thoughts
Setting up Power of Attorney isn’t about taking away your parent’s independence—it’s about protecting their dignity and future. Dementia progresses, but your preparation can ensure that the right decisions are made at the right time. Considering that more than 6 million Americans live with Alzheimer’s (Alzheimer’s Association, 2024), legal planning is no longer something to delay. As more families embrace aging in place, tools like Power of Attorney and long-term care planning are critical—not optional.
