Attorney-in-Fact vs. Power of Attorney: Understanding the Differences

Nov 18, 2025

Understanding legal terms like "Attorney-in-Fact" and "Power of Attorney" is crucial for anyone planning their estate or managing someone else's affairs. While these terms are often used interchangeably, they have distinct meanings and implications.

What is a Power of Attorney?

A Power of Attorney (POA) is a legal document that grants one person the authority to act on another's behalf. This document can cover a range of responsibilities, from financial decisions to healthcare choices. The person granting this power is known as the "principal," while the person receiving it is the "agent" or "Attorney-in-Fact."

There are different types of POAs, including general, limited, and durable. A general POA allows the agent to make a wide array of decisions, whereas a limited POA is restricted to specific tasks. A durable POA remains effective even if the principal becomes incapacitated.

Who is an Attorney-in-Fact?

An Attorney-in-Fact is the individual appointed by the principal through the Power of Attorney document to act on their behalf. This role can be filled by a trusted family member, friend, or even a professional like an attorney. The Attorney-in-Fact is obligated to act in the principal’s best interest, adhering to the terms set out in the POA document.

The responsibilities of an Attorney-in-Fact can vary widely depending on what the POA specifies. They may manage financial accounts, make healthcare decisions, or handle real estate transactions. It is essential to choose someone who is trustworthy and capable of handling the duties assigned.

Key Differences

While the terms Power of Attorney and Attorney-in-Fact are related, they are not synonymous. The Power of Attorney is the legal document itself, whereas the Attorney-in-Fact is the person designated to carry out the tasks outlined in the document. Understanding this distinction is crucial when setting up or executing a POA.

Another important difference lies in the scope of authority. The Power of Attorney document defines the extent of the Attorney-in-Fact’s powers, which can be broad or limited. It's vital to clearly outline these parameters to avoid any misunderstandings or legal issues.

Choosing the Right Attorney-in-Fact

Selecting the right Attorney-in-Fact is a critical decision. Consider the following factors:

  • Trustworthiness: The individual should be reliable and have the principal’s best interests at heart.
  • Financial Acumen: If the POA involves financial decisions, the agent should have a good understanding of financial matters.
  • Availability: Ensure that the person has the time and ability to fulfill the responsibilities.
