Siblings fight over a parent’s power of attorney because one name on one document gets heard as a verdict on everything else: who your parent trusts, who has been passed over, and who will be left carrying the plan from here. The document itself is narrower than that. The money decisions are real, but after 28 years in finance I can tell you the money is where the fight shows up, not where it starts. Underneath it is the work: who is carrying it, and who is not. I am Jessica Cannon, a CPA with 28 years of financial experience and a Certified Dementia Practitioner, and I know this fight from the inside. I resented my siblings for not showing up the way I needed them to, and when my father passed, I didn’t speak to one of my siblings for eight years.

I lived four years of misdiagnoses with my own mother, vascular dementia, bipolar disorder and early-onset Alzheimer’s, before we finally landed on frontotemporal dementia, so when a family fighting over what to do next sits down with me, I see my own family in them. My practice works with families nationwide through virtual coaching, with in-person roots in Austin and Central Texas.

The way through is to shrink the name back to its actual size: a person your parent trusts with one job, inside a family plan that gives everyone else a defined part. That is far easier to settle early, which is why the timing matters as much as the tempers.

Key Insights

The decision a family can make this month is to treat the power of attorney as one job, not a ranking. Siblings hear the name as a ruling on trust, love and who will carry the care, while the research traces most sibling conflict in caregiving to unshared work. The fight sharpens as a parent with dementia declines, because the one person who could settle it is losing the capacity to. So write down what the named sibling does and does not do, hear your parent’s reasons, and give every other sibling a defined part.

Why does the power of attorney turn into a fight so fast?

Because it is often the first decision that makes a family rank itself out loud. A power of attorney does something narrow: it names who your parent trusts to act for them, in the matters the document lists. The family hears something wider, a ranking of the children and a job description nobody has written down, and each sibling answers the part they heard.

The research on adult-child caregivers points at the job description. In a 1991 study of 100 adult children caring for a parent, published in The Gerontologist, 40 percent were in conflict with another family member, usually a sibling, and most of that conflict arose because the relative was not providing enough help. A 2024 national study of 453 dementia family caregivers, led by researchers at UTHealth Houston’s Cizik School of Nursing, found that adult children were more likely to experience high amounts of family conflict, which it measured as disagreement over caregiving workloads, respect toward the caregiver and how the person with dementia is treated.

Workload, respect and care are the lived parts of the job. The name on the document becomes the place where the fear, grief and resentment over who is left holding the plan finally get said, which is why the argument can feel out of proportion to a single signature.

What does being named, or passed over, feel like?

For the sibling who is named, it often feels less like power than like weight. Federal consumer guidance for agents treats that sibling as a fiduciary, bound to act only in the parent’s best interest and exposed to removal, a lawsuit or repayment for falling short. Unless the family divides the rest of the work, the appointments, the bills and the calls land on the same desk as the paperwork.

For the siblings who are not named, the same moment can land as a verdict that they were not trusted, not needed or not told. Maybe you stopped seeing the bank statements, or you heard about the signing afterward. Your parent chooses, while they have capacity, and they do not need anyone’s permission. That is the part families find hardest.

Both experiences are real at once. The named sibling hears criticism of a job they may never have wanted to do alone, the others hear silence about a parent they love just as much, and each can be wrong about what the other meant.

What else are siblings arguing about underneath the name?

Usually four older things. In the Family Dynamics pillar of the Proactive Caregiver Method, I name the forces that turn a sensible conversation into a standoff, and each one attaches itself to the name on the document.

The first is the one families notice last: you had different parents. The mother who raised the eldest is not quite the mother who raised the youngest, so each of you is protecting a slightly different person and can be sincere while disagreeing about what she would want. The other three are the childhood roles you were cast in, the different speeds at which each of you is grieving, and a money anxiety that, as I put it on my siblings page, is “Not greed. Fear.” Transparency eases that fear, and secrecy feeds it.

Here is how those forces can sound across the table. The lines are illustrations, not quotes from any family.

Why does the fight get worse as a parent declines?

Because the one person who could settle it is losing the ability to. The Alzheimer’s Association states that a person living with dementia keeps the right to make their own decisions as long as they have legal capacity, and that a power of attorney does not let the agent override them until that capacity is gone. While it lasts, your parent is the family’s tiebreaker, and siblings can feel that tiebreaker slipping long before anyone says so.

The legal half runs on a clock as well. Federal planning guidance from the National Institute on Aging says financial documents such as a durable power of attorney must be created while the person still has the legal capacity to make decisions, and in my experience families often have about a year after a diagnosis before capacity drops below the legal threshold for signing. Capacity is judged one document at a time, which I explain in how capacity works for signing legal documents after a diagnosis, but for a family in a stalemate the arithmetic is simple: every month spent arguing about the name comes out of the time your parent has to make the choice.

If that time runs out, a court may end up choosing instead of your parent. The Alzheimer’s Association describes guardianship as generally considered when a person with dementia can no longer provide for their own care and the family cannot agree on the care needed, or there is no family, and notes that the process takes time, runs through an attorney and a courtroom, and leaves the guardian supervised by the court. I compare that route with a power of attorney in guardianship vs power of attorney for a parent with dementia.

Texas makes the trade concrete. The Texas State Law Library’s guardianship guide describes a durable power of attorney as much less restrictive than a guardianship, because it lets the principal name the actions the agent is authorized to take. Rules differ by state, but the document your family is arguing about is one of the less restrictive routes, and that route stays open only while your parent can still sign one.

How do you make the choice without it becoming a verdict?

By treating it as a decision about one job, made in the open, with your parent’s reasons on the table. What turns a family that is fighting into a family that is functioning is clarity and defined purpose, and for this particular decision that comes down to five moves.

• Hear the reasons from your parent while they can give them. The National Institute on Aging suggests starting with a meeting that includes the older person and everyone who will be involved in their care, held in a calm moment rather than a crisis. Reasons your parent gives in their own words, such as who lives closest or who is good with numbers, leave the rest of the family something to respond to other than a verdict.
• Name the job before you argue about the person. Write down what the named sibling will be responsible for and what they will not, so the name stops standing in for the whole plan.
• Give every sibling a defined seat. My Sacred Assignment framework starts from the six roles every family already has, most of them never named, which is why families fight about who is not doing enough. In practice, the named sibling pays the bills and talks to the bank, a sister who lives an hour away covers the Saturday respite, and a brother across the country becomes the Researcher who finds the memory care options and sends the weekly update. The full framework sits on my page for families where siblings disagree about a parent’s care, and how siblings can make power of attorney work as a family walks through dividing the roles.
• Set the information terms before anyone has to ask. Agree what gets shared, how often and where decisions are written down, so nobody has to ask permission to know what is happening to their own parent.
• Keep the legal questions with a lawyer. Whether two of you can share power of attorney, or whether the named sibling can limit your visits, depends on the document and your state, and I have answered both separately.

What if the family still cannot agree?

Your family does not have to agree about the past for any of this to work. It needs one job named honestly, a real part for every sibling, and the legal half finished in time. If you stall anyway, I have listed the questions to ask a mediator or elder law attorney before you pay for that hour.

Building that plan with someone who has lived it is the work I do with families in monthly coaching. It starts with a short discovery call over video: you tell me what is happening in your family, I tell you where your biggest vulnerability sits and whether coaching is the right fit, and if it is not, I will say so and point you somewhere better.

Frequently Asked Questions

Q: What if our parent chooses a sibling the rest of us do not trust?

A: The choice is your parent’s while they have the legal capacity to make it. What the rest of the family can shape is the plan around the name: what the named sibling shares, how often, and who else holds a defined role. The Consumer Financial Protection Bureau’s guide for agents suggests sharing accountings or summaries of spending unless the parent has said not to. If the worry is misuse rather than style, I have listed the warning signs of power-of-attorney misuse.

Q: What if one sibling refuses to talk about the power of attorney?

A: Refusal can be grief running on a different timeline, so it helps to name that possibility instead of reading it as indifference. Your parent does not need every child’s agreement to sign, and the decision runs on your parent’s timeline rather than the reluctant sibling’s. What the family loses without that sibling is their share of the plan, so leave a defined role open for them, even a small one they can step into when they are ready.

Q: Is it a bad sign if my parent named my sibling instead of me?

A: Not on its own. A parent may choose for ordinary reasons, such as who lives closest, who is good with numbers or who has the time. Being left out is painful, and it is not evidence that anything improper happened. What protects your place in the family is a named role in the plan and a clear agreement about what you will see, both fair to ask for directly.

Q: What if the sibling who was named does not want the job?

A: Saying so now is kinder than burning out later, and far easier while your parent can still change the document. The Alzheimer’s Association recommends that the agent have a thorough conversation with the parent about what the responsibility entails, which is the place to say what you can and cannot carry. Sometimes the answer is a smaller job rather than a different person, with siblings sharing the appointments, the research and the updates. Who serves as a backup agent is a question for an elder law attorney in your parent’s state.
