Power of Attorney, Guardianship, Capacity & Competency: What’s the Difference?
September 2026
When someone is having difficulty managing their healthcare, finances, or other important decisions, families often start hearing words like power of attorney, guardianship, capacity, and competency.
Sometimes those words are even used interchangeably. But they don’t all mean the same thing.
Understanding the basic differences can help patients and caregivers ask better questions, communicate more clearly with professionals, and figure out what kind of help they may actually need.
Before We Go Further
If terms like advance directive, living will, and healthcare power of attorney are completely new to you, you may want to start with the previous Sunshine Notes article:
Advance Directives, Living Wills & Power of Attorney: Why It’s Better to Plan Before a Crisis
That article walks through the basics of advance care planning, why these conversations are important, and some of the things families can do before an emergency happens.
This article takes the conversation one step further by looking at something that can become especially confusing for families: who actually has the authority to make decisions, and what happens when someone’s ability to make a decision is in question?
What Is Power of Attorney?
A power of attorney, often shortened to POA, is a legal document that gives another person authority to act on someone’s behalf in certain situations.
The person creating the power of attorney determines who they want to appoint and, depending on the document, what authority that person will have.
There are different types of powers of attorney. For example, someone may have authority related to financial matters without having authority to make healthcare decisions.
A healthcare power of attorney may name someone to make healthcare decisions if the individual becomes unable to make or communicate those decisions. The exact authority and when it becomes effective depend on the document and applicable state law.
Does Having POA Mean You Control Everything?
No. This is an important misconception.
Simply hearing that someone “has POA” doesn’t tell you exactly what that person is authorized to do.
You need to know what type of power of attorney it is, what authority the document actually grants, when that authority becomes effective, whether it is still valid, and what applicable state law allows.
Having a power of attorney also does not automatically mean that the person who created it has lost the ability to make their own decisions.
What Is Guardianship?
Guardianship is different from power of attorney.
Generally, guardianship involves a court process in which a court appoints someone to make certain decisions for another person after the legal requirements for guardianship have been met.
The guardian’s authority comes from the court. Depending on the jurisdiction and circumstances, that authority may be limited to particular areas or may be broader.
Because guardianship can significantly affect a person’s legal rights and because laws vary by state, questions about whether guardianship is appropriate should be discussed with a qualified attorney.
POA and Guardianship Are Not the Same Thing
One of the easiest ways to understand the difference is to think about where the authority comes from.
With a power of attorney, a person generally chooses another person and grants authority through a legal document.
With guardianship, authority is generally granted through a court process.
That distinction matters. It also means that being someone’s spouse, adult child, caregiver, or emergency contact does not necessarily give you the same legal authority as an appointed healthcare agent or court-appointed guardian.
What Does Capacity Mean?
This is where things can become more complicated.
In healthcare, capacity generally refers to a person’s ability to understand relevant information and make an informed decision.
Capacity isn’t necessarily all or nothing. A person may be able to make one type of decision while having difficulty with another. Capacity can also change.
Someone’s ability to make a decision may be affected by the complexity of the decision, illness, medication, delirium, cognitive impairment, or other circumstances.
This is why statements like “She has dementia, so she can’t make decisions anymore” can oversimplify a much more complicated issue. A diagnosis alone doesn’t answer every question about someone’s ability to participate in a particular decision.
What About Competency?
People often hear that capacity is a medical determination while competency is a legal determination.
That can be a helpful starting point for understanding the concepts, but the terminology isn’t that simple everywhere.
Historically, “competency” or “incompetency” was more commonly associated with legal determinations, while healthcare professionals assessed decision-making capacity.
Today, terminology varies by jurisdiction, and many laws use terms such as capacity, incapacity, legal capacity, or clinical capacity instead.
The important takeaway for patients and caregivers isn’t memorizing the terminology. It’s knowing who is making the determination, what specific decision is being considered, and what that determination actually means.
Needing Help Is Not the Same as Being Unable to Decide
This may be one of the most important distinctions for families to understand.
Someone may need help remembering appointments, organizing medications, understanding insurance, reading complicated paperwork, communicating with multiple providers, keeping track of bills, comparing options, or asking questions.
None of those things, by themselves, automatically mean that the person cannot participate in decisions about their own life or healthcare.
Support and decision-making authority are not the same thing.
Whenever possible and appropriate, patients should remain involved in conversations and decisions affecting them.
Questions Families Can Ask
If you’re unsure who has authority to make a particular decision, instead of assuming, start asking questions.
You might ask:
• Is there a healthcare power of attorney or advance directive?
• Who is named in the document?
• What authority does the document provide?
• Is there a court-appointed guardian?
• What does the guardianship order authorize?
• Has there been an assessment related to this specific decision?
• Can the patient still participate in the conversation?
• Do we need legal guidance about what this document or court order allows?
Those questions can help clarify the situation without jumping immediately to conclusions about what someone can or cannot do.
Why These Distinctions Matter
Words matter, especially when we’re talking about someone’s right to make decisions about their own healthcare, finances, living situation, or life.
Saying someone “can’t make decisions” is a significant statement.
So is assuming that a family member automatically has authority because they’re the spouse, child, caregiver, or person who usually handles everything.
Understanding the difference between supporting someone, acting under a power of attorney, and serving as a court-appointed guardian can help families know when they need additional guidance.
Keeping Important Documents Organized
If your family has powers of attorney, advance directives, guardianship documents, or other important records, knowing where those documents are is important too.
The Sunshine Advocacy Navigation Binder provides one place to organize healthcare and caregiver information, including legal and advance planning documents.

When You’re Not Sure, Ask
Families don’t have to become experts in healthcare law.
But understanding a few basic distinctions can help you recognize when a situation requires more information and when it’s time to involve the appropriate professional.
A patient advocate can help with education, organization, communication, and healthcare navigation.
A healthcare professional can address clinical questions and assessments within their scope.
An attorney can provide advice about legal rights, powers of attorney, guardianship, and the laws that apply to your specific situation.
Knowing which question belongs to which professional is an important part of navigating complicated care.

Advance Directives, Living Wills & Power of Attorney: Why It’s Better to Plan Before a Crisis
August 2026
Most of us don’t like thinking about a time when we might not be able to make or communicate our own decisions.
Unfortunately, a medical emergency is often when families discover they never had some of these important conversations.
Who should make healthcare decisions if you can’t speak for yourself?
Does that person actually know what you would want?
Where are your important documents?
Does your family even know they exist?
Advance care planning gives you an opportunity to answer some of those questions before you’re in the middle of a crisis.
What Is Advance Care Planning?
Advance care planning is the process of thinking about and communicating your wishes for future medical care, particularly if illness or injury leaves you unable to communicate those wishes yourself.
It can include conversations with family members and healthcare providers as well as legal documents such as advance directives.
This isn’t something that only matters for older adults or people with serious illnesses. Unexpected medical situations can happen at any age.
Learn more from the National Institute on Aging:
What Is an Advance Directive?
An advance directive records your healthcare instructions for a future time when illness or injury prevents you from expressing those choices yourself.
Depending on where you live, an advance directive may include different documents or use different terminology. Two common parts of advance care planning are a living will and a healthcare power of attorney.
What Is a Living Will?
A living will allows you to document your preferences for certain types of medical treatment if you become unable to make those decisions yourself. This may include preferences involving life-sustaining treatment and other medical interventions.
A living will is different from a traditional will. A traditional will generally addresses what happens to your property and assets after your death. A living will addresses certain healthcare wishes while you are still living.
Read more from the American Bar Association:
What Is a Healthcare Power of Attorney?
A healthcare power of attorney allows you to name someone you trust to make healthcare decisions for you if you are unable to make or communicate those decisions yourself.
You may also hear this person called a healthcare agent, proxy, representative, or surrogate.
Choosing this person is about more than picking the family member who lives closest to you. Consider whether the person understands your wishes and values, is comfortable asking healthcare providers questions, can advocate for what you would want even if their personal choice might be different, can communicate with other family members during a stressful situation, and is willing to take on the responsibility.
Most importantly, talk to them. Finding out during an emergency that someone has been named as a healthcare decision-maker is not ideal for anyone.

What About Financial Power of Attorney?
Healthcare and financial powers of attorney are not necessarily the same thing.
A financial power of attorney may authorize someone to handle certain financial or legal matters on another person’s behalf. Exactly what authority that person has depends on the document and applicable state law.
Someone having authority to help with finances does not automatically mean they have authority to make healthcare decisions, and vice versa.
Because powers of attorney are legal documents and state requirements vary, an attorney can help you understand which documents are appropriate for your individual situation.
Having the Documents Isn’t Enough
Completing the paperwork is important. But the people who may need these documents need to know they exist and where to find them.
Consider whether your healthcare agent has a copy, whether your healthcare providers have the appropriate documents in your medical record, whether a trusted family member knows where originals or copies are stored, whether the documents can be accessed during an emergency, and whether you have talked with the person you’ve chosen about what actually matters to you.
A beautifully organized document locked away somewhere nobody can access isn’t very helpful during an emergency.
Keep the Conversation Going
Advance care planning isn’t necessarily something you complete once and never think about again.
Your health can change. Your relationships can change. You may move to another state. The person you originally selected to make decisions may no longer be the person you want in that role. Your own wishes may change over time.
Review your documents periodically and after significant life changes, and make sure the appropriate people have updated copies.
Getting Your Important Information Organized
Advance planning isn’t only about completing legal documents.
During a medical emergency, families may suddenly need access to information about medications, medical history, healthcare providers, insurance, emergency contacts, advance directives, powers of attorney, allergies, and current treatments.
Knowing where that information is can make an already stressful situation easier to navigate.
The Sunshine Advocacy Navigation Binder was created to help patients and caregivers organize important healthcare information in one place. It includes sections for medical information, medications, providers, insurance, emergency contacts, and organizing legal and advance directive documents.

The binder is an organizational tool. It does not create or replace legal documents or provide legal or medical advice.
Why Planning Ahead Matters
Advance care planning isn’t about expecting something bad to happen.
It’s about making sure your voice can still be part of your care if there comes a time when you can’t speak for yourself.
It can also give the people who care about you something incredibly valuable: guidance.
Instead of asking, “What do I think they would want?” they have an opportunity to understand what you actually want.
Sometimes advocacy starts long before there’s a crisis. Sometimes it starts with a conversation.

Social Security Adds 14 Conditions to Its Compassionate Allowances List: What Families Should Know
It All Begins Here
August 2026
The Social Security Administration (SSA) recently announced the addition of 14 medical conditions to its Compassionate Allowances list, bringing the total number of conditions on the list to 314.
For individuals and families dealing with a serious diagnosis, this is an important update. The disability application process can be lengthy and complicated, but the Compassionate Allowances program allows Social Security to quickly identify certain claims involving particularly serious medical conditions.
So, what does that actually mean for patients and families?
What Are Compassionate Allowances?
The Compassionate Allowances program helps the Social Security Administration recognize disability applications involving certain severe medical conditions. Once identified, these claims may be reviewed more quickly than applications moving through the standard disability determination process.
The program doesn't create a separate disability benefit. Instead, it can expedite the processing of an application for Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) when an applicant has a qualifying condition.
For someone coping with a severe or life-altering diagnosis, reducing the amount of time spent waiting for a disability determination can be incredibly important.
Which Conditions Were Added in 2026?
Social Security added the following 14 conditions to the Compassionate Allowances list:
Adenylosuccinate Lyase Deficiency – Neonatal Form and Type 1
Aicardi Syndrome
Baraitser-Winter Syndrome
Beare-Stevenson Cutis Gyrata Syndrome
Bohring-Opitz Syndrome
CASK-Related Gene Disorders
Hepatosplenic T-Cell Lymphoma
Lafora Disease
Malignant Migrating Partial Seizures of Infancy (MMPSI)
OPHN1 Syndrome
Primary Cardiac Sarcoma
Primary Intracranial Malignant Melanoma
Uveal Melanoma – with Metastases
Warburg Micro Syndrome
These additions bring the Compassionate Allowances list to 314 qualifying conditions.
Does Having a Condition on the List Guarantee Disability Benefits?
This is an important distinction.
Having a diagnosis included on the Compassionate Allowances list does not mean that someone automatically receives SSDI or SSI benefits.
Applicants still have to meet Social Security's eligibility requirements, and SSA will need appropriate medical information to evaluate the claim.
The difference is speed.
When Social Security identifies a claim involving a Compassionate Allowance condition, it can be flagged for expedited processing rather than moving through the traditional disability determination timeline.
What Should You Do If Your Diagnosis Is on the List?
If you or someone you care for has one of these conditions — or another condition already included on the Compassionate Allowances list — it is helpful to know about the program when applying for disability benefits.
Gathering clear medical documentation is still important. This may include information such as your:
Diagnosis
Treating providers
Medical records
Pathology or testing results
Medications and treatments
Other documentation related to your condition
Not sure if your condition is on the list?
The Social Security Administration maintains a complete and updated list of Compassionate Allowances conditions.

Why Updates Like This Matter
When you're dealing with a serious diagnosis, you shouldn't also have to become an expert in every healthcare system, insurance rule, and government program overnight.
Unfortunately, patients and caregivers often don't know that programs or expedited pathways like this exist until someone tells them.
That's why understanding your options matters.
At Sunshine Patient Advocacy & Support Services, my goal is to help patients and families make sense of complicated systems, organize their next steps, and identify resources that may help along the way.
Sometimes advocacy starts with something as simple as knowing which questions to ask.
