When you and your siblings are stuck on who holds power of attorney for a parent, the fastest way through is not another family phone call. It is booking time with a neutral professional, a mediator or an elder law attorney, and walking into that meeting with specific questions already written down. Vague venting gets you another round of hurt feelings. Specific questions get you a document, a process, or at minimum a clear next step.

Key Insights

• Siblings often stall on power of attorney because old family roles resurface, more often than because anyone is trying to steal from Mom or Dad.
• A mediator helps siblings talk to each other. An elder law attorney tells you what the law actually allows and can draft or fix the document itself. Some situations need both, in sequence.
• The seven questions below work for either professional. Bring the same list to your first call.
• If your parent can still express a clear preference, that preference carries real legal weight and should be the first thing on the table.
• If mediation stalls or one sibling refuses to participate at all, that is your signal to move to an elder law attorney and, if needed, a court-supervised process.

Why do siblings get stuck on power of attorney in the first place?

Power of attorney disagreements often start as something other than a legal dispute. In many families, they start as old sibling dynamics wearing a legal costume. Research from the Family Caregiver Alliance has found that siblings are frequently cited as a significant source of interpersonal stress for adult children caring for a parent with dementia, and that the trigger is often an unequal split of responsibility rather than a genuine disagreement about the parent’s wishes. That is not true of every family, and it is worth naming plainly with the mediator or attorney rather than assuming it applies to yours.

One sibling has been driving Mom to appointments for two years. Another sibling lives across the country and finds out about a POA decision after it is already made. A third sibling was named agent on paper but has not done anything with the authority. None of that is illegal. All of it is exhausting, and it is exactly the kind of standoff a mediator or attorney is trained to work through.

The distinction matters because it changes who you call first. If the fight is about who feels shut out or unappreciated, a mediator can often get you further than a lawyer will. If the fight is about whether a document is valid, whether an agent is overstepping their authority, or whether your parent currently has the capacity to sign anything at all, you need an elder law attorney in the room.

Should you call a mediator or an elder law attorney first?

Both professionals can help, but they solve different problems. Use this as a starting point, then let the professional you call tell you if you actually need the other one too.

Mediation does not always end in a signed agreement, but it regularly moves families forward even when it does not: siblings leave the table understanding each other’s position better, which makes the next conversation shorter instead of longer. That is a meaningful outcome, but it is not a substitute for legal review when the underlying question is whether a document is valid or whether an agent is following it.

What are the 7 questions to bring to that first meeting?

Whether you end up in a mediator’s office or an elder law attorney’s conference room, these seven questions get the conversation past feelings and onto facts. Bring the same list to both if you end up needing both.

1. Does our parent currently have the capacity to state a preference, and how is that being assessed?
Texas law treats a durable power of attorney as valid based on the principal’s capacity at the time of signing. If your parent can still clearly express who they want handling their affairs, that preference should shape the entire conversation, not get lost in sibling back and forth. Ask the professional how capacity gets evaluated and by whom, since that answer changes everything else on this list.

2. What does the existing power of attorney document actually say?
Families often argue about what a document allows without anyone having read it closely. Ask the attorney or mediator to walk through the specific powers granted, whether there are co-agents named, and whether the document requires agents to act jointly or allows either one to act alone.

3. Can the current agent be changed, and what does that process require?
If one sibling was named years ago and circumstances have shifted, ask what it actually takes to revoke or amend the existing POA. This is a legal question more than a mediation question, but a mediator can help the family agree on whether to pursue it before anyone spends money on redrafting.

4. What happens if we cannot reach agreement at all?
Ask directly what the fallback looks like. For an attorney, that might mean explaining when a guardianship proceeding becomes necessary. For a mediator, it might mean naming a deadline after which the family agrees to bring in an attorney. Either way, you want a concrete answer, not a shrug.

5. How will decisions about money and medical care be documented going forward?
Whatever gets agreed on, in mediation or with legal advice, needs to be written down. Ask how the professional recommends documenting decisions so that six months from now nobody is relitigating what was decided.

6. What does this cost, and what is included?
Ask for a clear fee structure up front. Mediators typically charge by the session; elder law attorneys often charge for an initial consultation separately from document drafting or ongoing representation. Get the number before you commit, and ask what happens if the process takes longer than expected.

7. What is the very next step after this meeting?
Do not leave without a concrete action item and a date attached to it. A vague “let’s talk again soon” is how these situations drag on for years. A specific next step, even a small one, is how they actually resolve.

What happens if the meeting still does not resolve things?

Sometimes one sibling refuses to participate, or mediation surfaces a deeper legal problem, such as evidence that an agent is not acting in the parent’s interest. That is not a failure of the process. It is the process doing its job by showing you where the real problem sits.

At that point, an elder law attorney can advise whether a formal legal step, such as a guardianship or a court petition to compel an accounting from the current agent, is appropriate. This is not a decision to make based on a blog post or a family group text. It is a decision to make with a licensed attorney who has reviewed your parent’s actual documents and circumstances, because the wrong move here can cost time, money, and the very family relationships you are trying to protect.

This is also where a financial strategist’s role gets clearer, and more limited than people expect. As a CPA and Certified Dementia Practitioner, my work is running the numbers and the timeline underneath a decision like this: what a guardianship proceeding might realistically cost, how a delayed decision affects Medicare or long-term care planning, what documentation an elder law attorney will likely ask for. I am not able to tell you what a court will decide or draft the legal document itself, and any strategist who tells you otherwise is not being straight with you. My job is making sure that by the time you sit down with the attorney, you are not starting from zero.

Frequently Asked Questions

Can one sibling really keep another sibling away from a parent?
It depends heavily on the specific facts, including what the power of attorney document says, whether there is a separate guardianship order, and whether there are safety concerns involved. A sibling holding financial power of attorney does not automatically have the legal authority to restrict another family member’s contact with the parent, but the details matter enormously and this is exactly the kind of question to bring directly to an elder law attorney with the actual documents in hand, rather than trying to resolve it over text messages.

Do we need a lawyer if we are willing to try mediation first?
Not necessarily to start. Many families begin with a mediator specifically because it is less adversarial and often less expensive than an attorney-led process. That said, any agreement reached in mediation about power of attorney should still be reviewed by an elder law attorney before it is finalized, to confirm it is enforceable and consistent with Texas law.

How long does this whole process usually take?
A single mediation session might resolve a communication breakdown in an afternoon. A dispute involving a contested POA, a capacity question, or a possible guardianship filing can take weeks to months, particularly if it moves into a court process. Ask the professional you hire for a realistic timeline based on your specific situation rather than assuming either extreme.

What if our parent no longer has the capacity to express a preference?
This is one of the more serious turns a family can hit, and it is squarely an elder law attorney’s territory rather than a mediation one. If capacity is genuinely in question, ask the attorney directly what evidence is typically required and whether a guardianship proceeding is the likely next step. Do not rely on a family consensus about capacity in place of a professional evaluation.
