What Is a Power of Attorney?

A power of attorney (POA) is a legal document that lets one person give another person authority to act on their behalf. The person granting the authority is usually called the principal. The person receiving it is called the agent or attorney-in-fact. Despite the term “attorney,” the agent does not have to be a lawyer.

A power of attorney can allow an agent to handle financial, legal, business, medical or personal matters. For example, a principal might authorize an agent to pay bills, manage a bank account, sign real estate documents, file tax forms or make health care decisions. The document can be broad or limited, depending on the principal’s needs.

A POA does not transfer ownership of the principal’s money or property to the agent. Instead, it gives the agent permission to act for the principal within the limits stated in the document. The agent generally must follow the principal’s instructions, act in the principal’s best interests and keep the principal’s property separate from the agent’s own property.

Common Types of Power of Attorney

Financial or general power of attorney

A financial POA authorizes an agent to handle money and property matters. Powers may include accessing bank accounts, paying expenses, managing investments, collecting benefits, filing tax returns and buying or selling property. A general POA may grant wide authority, while a limited POA may authorize only one task or transaction.

For instance, someone selling a home in another state might give an agent authority to sign the closing documents. That limited POA would not necessarily allow the agent to access the principal’s bank accounts or sell other property.

Durable power of attorney

A durable power of attorney remains effective if the principal later becomes incapacitated. This feature is important because a standard POA may end when the principal loses the ability to make decisions. A durable financial POA can help a trusted person manage bills, insurance, investments and other responsibilities without requiring a court-appointed guardian or conservator.

State laws differ on how durability must be stated. A document should clearly say that the authority continues during the principal’s incapacity if that is the intended result.

Springing power of attorney

A springing POA becomes effective only after a specified event, such as a doctor’s determination that the principal is incapacitated. This can give the principal more control while they are capable, but it may also cause delays or disputes over whether the triggering event has occurred. Some people prefer a durable POA that takes effect immediately for easier administration.

Medical or health care power of attorney

A health care POA allows an agent to make medical decisions when the principal cannot make or communicate those decisions. The agent may communicate with doctors, review medical information and consent to or refuse treatment, subject to state law and the principal’s instructions.

A health care POA is different from a living will. A living will states the principal’s preferences about certain end-of-life treatments, while a health care POA appoints a person to make decisions. These documents can work together.

What Can an Agent Do?

An agent may perform only the actions authorized by the POA and applicable law. A financial agent might be able to:

  • Pay the principal’s mortgage, rent, utilities and other bills.
  • Deposit checks and manage bank or investment accounts.
  • Apply for government benefits or manage insurance claims.
  • Sign contracts, tax documents or real estate paperwork.
  • Operate a business or manage rental property.

Some powers must be granted expressly rather than assumed. These may include making gifts, changing beneficiaries, creating or changing a trust, transferring assets to the agent or handling certain retirement accounts. Because these actions can significantly affect an estate, the document should address them specifically if they are appropriate.

An agent is not automatically allowed to make every decision for the principal. For example, authority to manage finances does not usually permit the agent to make medical decisions. Likewise, a health care agent generally cannot sell the principal’s home unless a separate legal authorization permits it.

How to Create and Use a Power of Attorney

The principal must generally have the mental capacity to understand what authority is being granted when signing a POA. The document should identify the principal and agent, describe the agent’s powers, state when the authority begins and explain when it ends. It should also name a successor agent in case the first choice cannot serve.

Signing and witnessing requirements vary by state. Many states require notarization, witnesses or both. A financial institution, hospital or government agency may also have its own forms or procedures. A lawyer can help coordinate the POA with a will, trust, beneficiary designations and other estate-planning documents.

After signing, the principal should provide copies to the agent and keep the original in a secure but accessible location. Relevant banks, financial firms, doctors or family members may need advance notice. The agent should ask each institution what documents it requires before attempting a transaction.

When acting, the agent should identify themselves as an agent rather than pretending to be the principal. A signature might read “Jordan Lee, as agent for Morgan Lee.” The agent should keep detailed records, save receipts and avoid mixing the principal’s funds with personal funds. Separate records make it easier to demonstrate that transactions were proper.

Risks, Safeguards and Ending a POA

A POA gives substantial control to another person, so choosing an agent is critical. The principal should select someone trustworthy, financially responsible and able to manage paperwork. A successor agent can provide backup. Limiting the authority to specific accounts, transactions or time periods can reduce risk.

Warning signs of misuse include unexplained withdrawals, changes to beneficiaries, unusual gifts, missing records or an agent using the principal’s money for personal expenses. The principal or family members may need to contact the financial institution, an elder-abuse agency, an attorney or law enforcement if they suspect exploitation.

A principal who still has capacity can usually revoke a POA by signing a written revocation and notifying the agent and relevant institutions. The principal should also retrieve copies and provide the revocation to anyone who relied on the original document. A POA generally ends when the principal dies; after that, the executor or personal representative named in the will handles the estate.

Because rules differ by state and the consequences can be significant, a power of attorney should not be copied casually from an unfamiliar form. A properly tailored document can make everyday financial and medical decisions easier during an emergency, while clear limits and careful recordkeeping help protect the principal’s money and preferences.
