The disadvantages of a power of attorney fall into a handful of categories: the agent you name can abuse the authority, the document itself can be drafted too broadly or too narrowly, banks and other third parties can refuse to accept it, it quietly fails to cover several things people assume it covers, and both ending it and fighting about it can be slow and costly. None of this means you should skip a POA. It means the setup matters more than people realize.
Your Agent Can Abuse the Authority
The most serious risk is the simplest one. The person you trust might not deserve it. An agent with authority over your bank accounts, investments, or property can drain funds, sell assets below market value, or redirect money to themselves. Financial exploitation through powers of attorney is a well-documented problem, particularly among older adults who may not be in a position to monitor day-to-day transactions. Family members are frequently the ones responsible, which makes the betrayal harder to detect and harder to report.
On paper, agents owe you a fiduciary duty. They must act in your best interest, keep accurate records, and avoid conflicts of interest. Breaking those duties can lead to civil liability, removal by a court, and in serious cases, criminal prosecution for theft or fraud. The protection breaks down in practice because someone has to notice first. If you are incapacitated and the agent controls the finances, there may be no one reviewing statements. By the time a relative or caregiver spots the pattern, the damage is already significant and recovery is uncertain.
Negligence counts too, not only intentional fraud. An agent who makes reckless investment decisions or fails to pay your bills and taxes can be sued for the resulting loss. The standard is generally whether the agent acted with the care a reasonable person would use in similar circumstances. Courts can order compensation, but collecting on that judgment is another matter, especially if the agent has already spent the money.
Things a Power of Attorney Cannot Do
People often assume a POA is a universal key. It isn’t, and several gaps catch families off guard during a crisis.
- Social Security and federal benefits. The Social Security Administration does not recognize powers of attorney for managing a beneficiary’s Social Security or SSI payments, and the Treasury Department takes the same position for all federal benefit payments. To manage those benefits for someone else, you have to apply to Social Security to become a representative payee, which is a separate appointment with its own oversight.1Social Security Administration. Frequently Asked Questions (FAQs) for Representative Payees
- Making or changing a will. An agent cannot create, modify, or revoke your will. Testamentary decisions are reserved to you personally.
- Voting and marriage. An agent cannot vote on your behalf or consent to a marriage for you.
The Social Security limitation is the one that most often blindsides families. Someone who has been carefully managing a parent’s finances under a POA discovers, often mid-crisis, that the document is worthless for the parent’s largest source of income.
Vague or Overbroad Drafting
The language in the document controls what the agent can do, and vague drafting is one of the most common mistakes. A POA that grants authority over “financial affairs” without listing which transactions are included leaves room for actions you never intended to authorize. A document that is too narrow can leave the agent unable to handle routine tasks at the exact moment you need them handled.
Certain powers are especially dangerous if granted carelessly. Making gifts, changing beneficiary designations, creating or modifying trusts, and altering survivorship rights usually require explicit authorization in the document. These are sometimes called “hot powers” because of the damage they can cause if misused. An agent with unrestricted gifting authority could transfer your assets to themselves or to others, shrinking your estate and creating tax consequences. If the gifting power is broad enough to include gifts to the agent, your assets may even be pulled into the agent’s estate for tax purposes.
Some states apply default rules that give agents broad authority unless the document specifically restricts it. In those jurisdictions, a general POA can carry more weight than the principal realized when signing. A download-and-sign form is rarely a safe way to handle this.
Automatic Termination Can Catch You Off Guard
A power of attorney doesn’t last forever, and the events that end it can create gaps if you haven’t planned around them.
Every POA terminates the instant you die. The agent’s authority disappears regardless of what the document says or what transactions are pending. The agent cannot pay your final bills, access your accounts, or handle your estate. That job goes to the executor named in your will, or to someone appointed by a probate court if you have no will. Families who relied entirely on a POA without preparing a will often face weeks of delay before anyone has legal authority to act.
If your agent is your spouse, most states automatically revoke the POA, or at least that spouse’s authority, when either of you files for divorce or legal separation. That is often what you want, but it creates a dangerous gap if you become incapacitated during divorce proceedings and haven’t named a backup agent.
The split between durable and non-durable POAs matters here. A standard non-durable POA terminates if you become incapacitated, which is exactly when you most need someone acting for you. A durable POA survives your incapacity, but only if the document explicitly says so. If you signed a POA years ago and aren’t sure whether it includes durability language, that is worth checking now rather than during a medical emergency.
The Springing POA Workaround Has Its Own Problems
Some people try to split the difference with a “springing” POA that activates only once they become incapacitated. The idea sounds appealing. In practice, someone has to determine that you are actually incapacitated before the agent can act, and that usually requires one or more physicians to certify your condition. Doctors can be reluctant to make that call, the document’s definition of incapacity may be ambiguous, and the whole process can take weeks while urgent decisions wait. Many estate planning attorneys steer clients away from springing POAs for this reason.
Third Parties May Refuse to Honor It
Having a legally valid POA and getting someone to accept it are two different experiences. Banks, brokerage firms, insurance companies, and healthcare providers sometimes refuse a POA that meets every legal requirement. Common reasons: the document is more than a few years old, the institution wants its own form signed instead, or a compliance officer unfamiliar with the law simply decides it looks wrong.
Refusals create real harm when timing matters. If you are trying to pay a parent’s mortgage from their account or authorize a medical procedure, a request for additional documentation or a legal opinion can delay things by days or weeks. Many states have enacted laws allowing agents to seek court orders forcing acceptance and to recover attorney fees from institutions that unreasonably refuse a valid POA. Filing suit against a bank is cold comfort when you need the money today.
Interstate Recognition Problems
A POA executed in one state should be valid in another under general constitutional principles, but theory and practice diverge. A financial institution in a different state may refuse a document that doesn’t match the formatting or statutory language its staff is used to seeing. If you own property, bank accounts, or investments in multiple states, a single POA may not work smoothly everywhere. Some attorneys recommend executing separate documents that comply with the laws of each state where you hold significant assets, which adds cost.
Keeping your POA current reduces refusal risk. Updating it every few years, even if nothing has changed, removes the “too old” objection. Some banks will also let you sign their own POA form in advance so it sits on file.
Revoking a POA Is Harder Than It Sounds
On paper, revoking a power of attorney is simple. Put the revocation in writing, sign it in front of a notary, and notify the agent and every institution that has a copy. Each step can become an obstacle.
The threshold requirement is mental competence. You must be of sound mind to revoke a POA, which creates a painful catch-22. If the reason you want to revoke is that your agent is exploiting your declining capacity, you may lack the competence the law requires to pull the authority back. At that point, the only option is for a family member or other interested party to petition a court for intervention. That process is expensive, slow, and requires evidence that can be hard to gather when the agent controls the financial records.
Even when the principal is fully competent, notification is a chore. Every bank, brokerage, insurance company, and healthcare provider that received a copy needs written notice of the revocation. If you miss one, that institution may keep honoring the agent’s authority in good faith. If the original POA was recorded with a county clerk’s office for real estate purposes, the revocation generally needs to be recorded in the same office. Miss any of these steps and the old agent may retain functioning authority long after you thought you had cut them off.
Family Conflict and Co-Agent Deadlock
Appointing one family member almost guarantees another will feel slighted, and the fallout can be severe. Siblings who weren’t chosen may view the arrangement with suspicion, second-guess every financial decision, or assume the agent is acting in self-interest. These tensions often sit quietly until a health crisis or large transaction brings them to the surface, at which point they can escalate fast.
Family members who believe the agent is mismanaging affairs can petition a court to review the agent’s conduct, remove the agent, or appoint a guardian or conservator instead. These proceedings are emotionally brutal and financially draining for everyone involved, and they typically stretch across multiple hearings over months.
The Co-Agent Trap
Some principals try to keep the peace by naming two or more children as co-agents who must act together. This sounds fair and frequently backfires. Co-agents who must agree on every decision can deadlock over medical treatment, investment choices, or whether to sell a property. When they can’t agree, nothing happens, which can be worse than a wrong choice. Banks are also more reluctant to work with multiple agents, partly because dual-signature requirements slow everything down and partly because the fraud profile looks different. If co-agents end up in court over a disagreement, the family argument has become a family lawsuit with legal fees on both sides.
A single primary agent with a named successor usually works better. If you want a second person involved, you can require the agent to provide periodic accountings to that person rather than giving both joint decision-making authority.
Medicaid Eligibility Can Be Destroyed by Well-Meaning Gifts
An agent with gifting authority can inadvertently destroy your eligibility for Medicaid long-term care benefits. Medicaid looks back five years from the date you apply and penalizes transfers made during that window that weren’t for fair market value. Gifts to family members, charitable donations, and even large cash expenditures without proper documentation can trigger a penalty period during which you are ineligible for benefits. An agent who makes well-intentioned gifts to grandchildren or transfers property to a relative inside that window can leave you unable to qualify for nursing home coverage when you need it most.
The risk is sharper because the agent may not understand Medicaid rules or know that long-term care could be in your future. If the POA includes broad gifting authority with no limitation tied to benefit eligibility, the agent has the legal power to make transfers that are financially catastrophic. Attorneys who draft POAs for older clients often build in specific gifting restrictions or require the agent to consult an elder law attorney before transferring assets above a stated threshold.
The Cost of Doing It Right, and the Cost of Fights
Creating a POA that actually protects you isn’t free. Generic forms are available online at little or no cost, and they tend to be the documents that produce the problems described throughout this article: vague authority, missing durability language, no gifting restrictions, no compliance with state-specific requirements. Having an estate planning attorney draft a tailored POA typically runs from a few hundred to a couple thousand dollars depending on complexity and location. If the POA involves real estate, recording it with the county clerk adds a modest fee.
The larger cost exposure comes from disputes. Litigating agent misconduct, seeking court removal, or petitioning for a conservatorship to override a POA can run into tens of thousands of dollars in legal fees. Mediation can reduce costs, but it requires all parties to participate voluntarily and may not be appropriate when fraud or serious abuse is in play. The irony is that the legal fees in POA disputes often come out of the principal’s own assets, draining the estate the document was meant to protect.
