What Is a Power of Attorney?

By September 18, 2026No Comments

A power of attorney is a legal document in which one person, called the principal, authorizes another person, called the agent or attorney-in-fact, to act on the principal’s behalf. The agent may be given authority to handle financial, legal, property, business, or other matters, depending on the terms of the document.

A power of attorney is an important estate planning tool because it allows a trusted person to assist with decision-making and financial management if the principal is unavailable, ill, disabled, or incapacitated.

Key Parties to a Power of Attorney

Principal

The principal is the person who creates the power of attorney and grants authority to the agent. The principal must have the legal capacity required to sign the document.

Agent

The agent is the person appointed to act for the principal. The agent has a fiduciary duty to act in the principal’s best interest, follow the principal’s instructions, and act only within the authority granted by the power of attorney.

An agent does not become the owner of the principal’s property. The agent is merely authorized to act on the principal’s behalf.

What Can a Power of Attorney Authorize?

A power of attorney can be broad or limited. Depending on the document, an agent may be authorized to:

  • Pay bills and manage bank accounts;
  • Buy, sell, or manage real estate;
  • Handle investments;
  • File tax returns;
  • Manage retirement benefits;
  • Operate or assist with a business;
  • Apply for public benefits;
  • Handle insurance matters;
  • Sign contracts or other legal documents;
  • Make gifts, if expressly authorized;
  • Create or modify certain estate planning arrangements, if expressly authorized; and
  • Conduct other financial or property-related transactions.

Certain powers may require specific language. For example, authority to make gifts, change beneficiary designations, or alter survivorship rights is often treated as a special power that should be clearly stated in the document.

Types of Powers of Attorney

  1. General Power of Attorney

A general power of attorney gives the agent broad authority to handle the principal’s financial and legal affairs. It may be useful when the principal wants the agent to have wide authority, but it should be granted only to someone highly trustworthy.

  1. Limited Power of Attorney

A limited power of attorney gives the agent authority for a specific purpose or transaction. For example, a principal may authorize an agent to sign closing documents for a real estate sale while the principal is unavailable.

  1. Durable Power of Attorney

A durable power of attorney remains effective even if the principal later becomes incapacitated. In Utah, powers of attorney are generally durable unless the document states otherwise. Durability is one of the main reasons powers of attorney are used in estate planning.

  1. Springing Power of Attorney

A springing power of attorney becomes effective only after a stated event occurs, usually the principal’s incapacity. The document should clearly explain how incapacity is determined and who may certify that the triggering event has occurred.

  1. Healthcare Power of Attorney or Advance Healthcare Directive

A financial power of attorney generally does not authorize medical decision-making. Healthcare decisions are usually addressed in a separate healthcare directive or healthcare power of attorney. In Utah, an Advance Health Care Directive may be used to appoint a healthcare agent and state treatment preferences.

Duties of an Agent

An agent under a power of attorney is a fiduciary. This means the agent must act with loyalty, care, and honesty. Common duties include:

  • Acting in the principal’s best interest;
  • Following the principal’s reasonable expectations and instructions;
  • Acting only within the authority granted;
  • Avoiding conflicts of interest;
  • Keeping the principal’s property separate from the agent’s property;
  • Maintaining accurate records;
  • Preserving the principal’s estate plan where known and appropriate;
  • Avoiding self-dealing unless expressly authorized; and
  • Cooperating with healthcare decision-makers or other fiduciaries when necessary.

An agent may be personally liable for misuse of authority, mismanagement of assets, or acting outside the scope of the power of attorney.

Choosing an Agent

The choice of agent is one of the most important parts of creating a power of attorney. The agent should be trustworthy, organized, financially responsible, and willing to act in the principal’s best interest.

Relevant considerations include:

  • The agent’s integrity and judgment;
  • Ability to manage financial and administrative matters;
  • Availability and responsiveness;
  • Familiarity with the principal’s wishes;
  • Ability to communicate with family members and professionals;
  • Willingness to keep records; and
  • Ability to avoid conflicts of interest.

It is also common to name one or more successor agents in case the first agent is unable or unwilling to serve.

Limits of a Power of Attorney

A power of attorney is powerful, but it has limits. An agent may not act beyond the authority granted in the document. The agent also may not use the power of attorney to benefit personally unless the document and applicable law permit it.

A power of attorney generally ends at the principal’s death. After death, authority to administer the estate belongs to the personal representative, trustee, or other appropriate fiduciary, not the agent under a power of attorney.

When Does a Power of Attorney End?

A power of attorney may terminate when:

  • The principal dies;
  • The principal revokes the power of attorney;
  • The document states that it terminates on a certain date or event;
  • The purpose of the power of attorney is completed;
  • The agent resigns, dies, becomes incapacitated, or is no longer qualified, and no successor agent is available;
  • A court terminates the agent’s authority; or
  • Other circumstances under applicable law cause termination.

If a principal revokes a power of attorney, financial institutions and affected parties should generally be notified to avoid continued reliance on the revoked document.

Why a Power of Attorney Matters in Estate Planning

A power of attorney helps avoid disruption if the principal becomes unable to manage financial affairs. Without a valid power of attorney, family members may need court authority, such as a conservatorship, to manage the principal’s property or finances during incapacity.

A well-drafted power of attorney can provide continuity, reduce administrative burden, and allow a trusted agent to act efficiently when assistance is needed.

Conclusion

A power of attorney is a legal document that allows a principal to appoint an agent to act on the principal’s behalf. It can be broad or limited, immediate or springing, and durable or non-durable. In estate planning, a durable financial power of attorney is commonly used to ensure that someone trusted can manage financial and property matters if the principal becomes incapacitated. Careful drafting and thoughtful selection of an agent are essential to making the document effective and reliable.
