The best person to name as your power of attorney is someone you trust completely with money, medical decisions, or both, who is organized enough to keep records, available enough to actually show up, and willing to take on tedious work during a stressful time. Deciding who to name as power of attorney trips people up because trust alone is not enough. Pick the wrong person and you risk financial loss or family conflict. Pick no one and a court may end up appointing someone for you.
What the Role Actually Involves
A power of attorney lets you (the “principal”) authorize someone else (the “agent” or “attorney-in-fact”) to act on your behalf. A financial POA can cover paying bills, managing bank accounts, handling investments, filing tax returns, or selling property. A healthcare POA authorizes your agent to make medical decisions if you can’t, including consenting to treatment, choosing providers, and in some cases making end-of-life decisions.
Your agent steps into your shoes for the matters the document covers. They sign checks in your name, talk to your doctors, negotiate with your insurance company, or sell your house. It is hands-on work that can consume hours every week, and mistakes come out of your pocket, not theirs. Keep that reality in mind as you think about candidates. You are not giving someone a title. You are handing them a job.
The Qualities That Actually Matter
Forget the generic advice about picking someone “responsible.” A few specific traits separate a good agent from a disastrous one.
Integrity Under Pressure
Your agent will face situations where doing the right thing is inconvenient, expensive, or unpopular with other family members. They need to be the kind of person who pays your bills before considering their own convenience, who will not “borrow” from your accounts, and who can tell a sibling “no” when the sibling wants money from your estate. Look at how a candidate manages their own finances. Someone drowning in debt or prone to impulsive spending is a poor choice for managing yours.
Willingness and Availability
An agent who lives three time zones away and travels for work forty weeks a year will struggle with tasks that require showing up in person, like meeting with a bank officer or attending a doctor’s appointment. Proximity is not always essential, since much can be done remotely and electronically, but it helps for healthcare decisions and situations where institutions want face-to-face verification.
More importantly, ask the person before you name them. An unwilling agent is worse than no agent at all. Someone who feels blindsided by the responsibility may do the job badly or refuse to serve when the moment comes.
Organization and Follow-Through
Managing someone else’s affairs means tracking bills, deadlines, insurance claims, tax filings, and medical records. Your agent needs to be the kind of person who keeps receipts and returns phone calls. This matters especially for financial POAs, where the agent has a legal duty to maintain detailed records of every transaction. If you are picking between two people you trust equally, pick the one whose own paperwork is in order.
Communication and Emotional Steadiness
Your agent will deal with banks, hospitals, insurance companies, government agencies, and your family. They need to communicate clearly, stay calm when a bureaucrat says “we can’t accept this document,” and advocate firmly without burning bridges. For healthcare decisions in particular, emotional steadiness matters enormously. The person making your medical choices during a crisis cannot fall apart when the choices get hard.
Values That Match Yours (for Healthcare)
For a healthcare POA (sometimes called a healthcare proxy), you want someone who understands your values around medical treatment, can handle emotionally charged conversations with doctors, and will advocate for what you would want rather than what they would want for you. You can name the same person who holds your financial POA, but they are separate documents, and the right person for one role is not automatically the right person for the other.
Family Member or Professional?
Most people name a spouse, adult child, or sibling. A family member already knows your preferences, understands your family dynamics, and typically serves without charging a fee. The downside is that family members may face conflicts of interest, especially if they stand to inherit from you. A child managing your money while also being a beneficiary of your estate creates an obvious tension, and other family members may question every decision.
Professionals like attorneys, accountants, or trust companies offer neutrality and expertise. They are accustomed to managing financial affairs, keeping records, and navigating institutions. They charge for their services, often hourly or as a percentage of managed assets, which can add up quickly over a long incapacity. A professional also will not know your personal preferences the way a family member would.
For many people, the best approach is naming a trusted family member as agent and having them consult professionals as needed for complex decisions like investment management or tax strategy. One scenario where a professional makes clear sense: when family relationships are strained and naming any one person would trigger conflict. A neutral third party can keep your POA from becoming a battleground.
Naming Co-Agents and Successor Agents
You can name two people to serve as co-agents, either requiring them to act jointly (both must agree on every decision) or independently (either can act alone). Joint co-agents provide a built-in check on each other, but every bank transaction, every medical consent form, every insurance call needs both signatures or both approvals. If the co-agents disagree, the matter may end up in probate court. Banks are sometimes reluctant to work with co-agents because of added fraud risk.
Independent co-agents are more practical but create a different problem: one agent may not know what the other is doing, leading to contradictory decisions or duplicated effort. If you name co-agents, spell out clearly in the document whether they must act jointly or may act independently.
Successor agents are less complicated and more universally recommended. A successor steps in only if your primary agent dies, becomes incapacitated, or resigns. Naming at least one successor avoids a gap in coverage that could force your family into court to get a guardian appointed.
What Your Agent Legally Owes You
Your agent is not just doing you a favor. They step into a fiduciary role, which means the law holds them to a high standard. The core duties include acting in your best interest (not theirs), avoiding conflicts of interest, keeping your assets separate from their own, and exercising reasonable care in managing your affairs.
Record-keeping is where agents most often get into trouble. Your agent should maintain a complete paper trail of every financial transaction: bank deposits, withdrawals, bill payments, investment trades, and any expenses paid on your behalf. Receipts matter, especially for cash transactions. If anyone later questions whether your agent handled your money properly, those records are the agent’s defense. Courts routinely order agents to produce a full accounting, and agents who cannot document their actions face personal liability for any funds they cannot explain.
An agent who breaches these duties can be removed by a court, ordered to repay misused funds, and held personally liable for financial harm to the principal. In egregious cases involving theft or fraud, criminal charges are possible. When you choose an agent, think about who would actually keep meticulous records, not just who you trust in the abstract.
What Your Agent Cannot Do
Even the broadest POA has limits, and knowing them affects how much weight to put on any single candidate. Your agent cannot make or change your will. They cannot vote on your behalf. They generally cannot make gifts to themselves from your assets unless you specifically authorized it in the POA, and even then, some states impose strict limits. Creating or modifying a trust in your name is also typically off-limits unless the POA explicitly grants that power.
The agent also cannot act contrary to your known wishes or outside the scope of authority the document grants. A financial POA does not authorize healthcare decisions, and a limited POA to sell your car does not allow the agent to empty your savings account. If the document says “manage my brokerage account,” that is the boundary.
After You Decide
Once you have picked a person, talk to them before anything is signed. Walk through what you would want in different scenarios, especially for healthcare decisions. Tell them where the document will be kept and who else has copies. A safe deposit box that only you can access defeats the purpose.
If you name a spouse and later divorce, do not assume the old document still works. Many states automatically revoke a POA naming a former spouse once the marriage ends, but institutions may not know about the divorce, and you are better off signing a new document naming someone else than relying on an automatic rule to carry the day. The same logic applies any time your relationship with your named agent changes materially. If you no longer trust the person you named, revoke the document and name someone you do.
