What Can a Financial Power of Attorney Do and Not Do?

A financial power of attorney can authorize your agent to do almost anything you could do with your own money — pay bills, manage bank and brokerage accounts, buy or sell real estate, run a business, deal with insurers, file tax returns — but it cannot authorize healthcare decisions, cannot change your will, cannot reach your Social Security benefits, and ends the moment you die. What a financial power of attorney can and cannot do depends partly on firm legal limits that apply to every such document and partly on the specific language the principal chose to include.

What an Agent Can Do

When the document grants broad authority, your agent steps into your financial shoes. Under the model law adopted by a majority of states, the categories of authority that can be granted include real property, personal property, banking, investments, business operations, insurance, government benefits, retirement plans, and taxes. In practical terms:

  • Bank accounts. Open or close accounts, make deposits and withdrawals, write checks. The agent typically has to present the power of attorney document to the bank.
  • Bills and living expenses. Mortgage or rent, utilities, insurance premiums, medical bills, and other recurring obligations.
  • Investments. Buy and sell stocks, bonds, mutual funds, and other securities in your brokerage accounts.
  • Real estate. Buy, sell, lease, or mortgage property you own. Many jurisdictions require the power of attorney to be recorded with the county recorder’s office before real estate transactions can proceed.
  • Retirement accounts. Make decisions about distributions, rollovers, and investment allocations within a 401(k), IRA, or other retirement plans.
  • Insurance. File claims, change coverage, and manage policy decisions.
  • Business interests. Manage or make decisions for a business the principal owns or has an interest in.

Which of these powers the agent actually has depends on which ones the document grants. A well-drafted document lists the specific categories rather than relying on vague “all financial matters” language.

Powers That Only Apply If the Document Says So

Certain actions are sensitive enough that the law treats them as off-limits unless the document specifically and expressly grants them. Under the widely adopted Uniform Power of Attorney Act, these include:

  • Making gifts of the principal’s money or property
  • Changing beneficiary designations on life insurance policies, retirement accounts, or other assets
  • Creating or changing survivorship rights on jointly held property
  • Creating, amending, or revoking a trust
  • Waiving the principal’s right to survivor benefits under a retirement plan
  • Delegating the agent’s authority to someone else

These are sometimes called “hot powers” because they can permanently alter an estate plan. If the document doesn’t explicitly mention them, the agent simply doesn’t have them, even if the document grants “all financial powers” in broad terms. This is one of the most commonly misunderstood points about a financial power of attorney, and it’s where vague or template documents cause the most problems.

What an Agent Cannot Do

No matter how broadly a financial power of attorney is written, several things are always outside its reach.

Make healthcare decisions. A financial power of attorney and a healthcare power of attorney are separate documents, usually with separate agents. Your financial agent has no authority to consent to surgery, choose a treatment plan, or make end-of-life decisions. That requires a healthcare power of attorney, sometimes called a healthcare proxy or medical power of attorney.

Make or change your will. An agent cannot draft, amend, or revoke your will or add a codicil. Wills require your personal intent and signature; that authority cannot be delegated through any power of attorney.

Act for personal benefit. An agent is prohibited from using the principal’s money or property for their own advantage. Self-dealing, conflicts of interest, and transactions that benefit the agent at the principal’s expense all violate the agent’s legal obligations, regardless of what the document says or how much the principal trusts them.

Act after the principal’s death. Every power of attorney terminates the moment the principal dies. The agent has zero authority to manage the estate, access accounts, or complete transactions after that point. Those responsibilities pass to the executor named in the will or an administrator appointed by the court.1Consumer Financial Protection Bureau. What Is a Fiduciary

Social Security, Federal Benefits, and the IRS

A fact that catches families off guard: a financial power of attorney does not give your agent authority to manage Social Security or SSI benefits. The Social Security Administration is explicit that the Treasury Department does not recognize a power of attorney for negotiating federal benefit payments, including Social Security checks. If the beneficiary can no longer manage their benefits, the person who wants to step in has to separately apply to become a “representative payee” through the SSA’s own process. A power of attorney, a joint bank account, or authorized-representative status on other accounts is not a substitute.2Social Security Administration. Frequently Asked Questions for Representative Payees

Taxes work on a similar split. A broad financial power of attorney can authorize an agent to prepare and file tax returns. But representing the principal before the IRS — speaking with agents, responding to audits, negotiating tax issues — requires IRS Form 2848, Power of Attorney and Declaration of Representative, filed separately. The representative generally has to be an attorney, CPA, enrolled agent, or other qualified individual, though family members can qualify in limited circumstances.3Internal Revenue Service.

The Agent’s Legal Duties Shape What They Can Do

Accepting a role as someone’s financial agent isn’t just permission to act. It’s a legal obligation to act carefully. An agent is a fiduciary, held to a higher standard than an ordinary person handling money. The CFPB sets out four core duties.4Consumer Financial Protection Bureau. Help for Agents Under a Power of Attorney

Act only in the principal’s best interest. Every decision must benefit the principal, not the agent and not other family members whose interests might conflict.

Manage money and property carefully. The standard in most states is the care and diligence a reasonable person would use in similar circumstances. Reckless investments, neglected bills, and sloppy management all fall short.

Keep the principal’s assets completely separate. Never deposit the principal’s money into your own account or mix assets. Title to property and accounts should stay in the principal’s name. Even paying a principal’s expense from your own pocket and reimbursing yourself creates muddled records that invite scrutiny from family members, courts, and adult protective services.

Keep detailed records. Track every receipt, disbursement, and transaction, with dates, amounts, payees, and reasons. Avoid cash payments where possible, because they’re nearly impossible to document after the fact. A court, a guardian, a government agency, or the principal themselves can demand the records, and “I don’t remember” is not a defense.1Consumer Financial Protection Bureau. What Is a Fiduciary

An agent who ignores these duties faces real consequences. On the civil side, the principal, their family, or a court-appointed guardian can sue to stop the abuse, recover assets, and seek damages. Criminal prosecution is also possible, especially when the principal is elderly or a vulnerable adult. A majority of states specifically define misuse of a power of attorney as financial exploitation, and depending on the state and the amount involved, charges range from misdemeanors to felonies carrying years of imprisonment.5U.S. Department of Justice. Elder Abuse and Elder Financial Exploitation Statutes Adult protective services agencies can investigate reports from concerned family members, bankers, or healthcare providers even before any lawsuit is filed.

When the Authority Ends

A financial power of attorney doesn’t last forever. The authority ends on any of the following events:

  • Death of the principal. The POA ends immediately. No exceptions.
  • Revocation by the principal. A competent principal can revoke at any time by putting the revocation in writing, notifying the agent, and informing any banks or institutions that have the original document on file.
  • Death or incapacity of the agent. If the agent dies or becomes incapacitated and the document doesn’t name a successor agent, the power of attorney terminates.
  • Divorce or legal separation from the agent. In a majority of states, filing for divorce or legal separation from an agent-spouse automatically terminates their authority unless the document specifically says otherwise.
  • Court order. A court can revoke a power of attorney if it finds evidence of abuse, fraud, or improper execution.
  • Fulfillment of purpose. If the document was created for a specific task, such as selling a particular house, the authority ends when that task is complete.

One wrinkle: revocation only works if people know about it. If the principal revokes an agent’s authority but the agent keeps making transactions before banks or other third parties learn, those transactions may still be legally binding. Notify every institution that has the POA on file, in writing, as soon as the revocation happens.

Getting Banks and Other Institutions to Honor It

Having a valid power of attorney and actually getting someone to honor it are two different experiences. Banks, brokerages, and title companies regularly push back on POA documents, especially older ones. Many state laws require financial institutions to accept a validly executed power of attorney but also allow refusal in certain situations, such as when the institution believes the document is forged, has been revoked, or that the principal is being exploited by the agent.6Consumer Financial Protection Bureau.

Some institutions insist that agents use the bank’s own proprietary POA form. Whether they can legally require that varies by state, but fighting a bank over form requirements takes time most agents don’t have. A few things reduce friction:

  • Have the principal sign the bank’s own form while they’re still competent, in addition to the general POA. That eliminates the most common objection.
  • Keep the document current. A POA signed 15 years ago is technically valid, but institutions get nervous about old documents.
  • Bring a certification or affidavit. An agent can sign a sworn statement confirming the principal is alive, the document hasn’t been revoked, and the authority is still in effect. Many institutions will accept this.
  • Know the leverage. If an institution refuses a valid POA without a legitimate reason, a court can order acceptance, and the institution may be required to pay attorney’s fees and court costs.6Consumer Financial Protection Bureau.

When an agent does sign on the principal’s behalf, the signature should make the relationship clear. The standard format is “Jane Smith, as agent for John Smith.” An agent who just signs the principal’s name without identifying themselves as agent invites a forgery accusation and creates confusion about who authorized the transaction.
