A power of attorney is one of those legal terms everyone’s heard but not everyone actually understands. At its simplest, it’s just a document that lets you give someone else the legal authority to act on your behalf. This guide gives you a clear, straightforward definition and overview, what a power of attorney actually is, the different types, and how it works in Tennessee.
This guide is part of our broader guide to estate planning law in Tennessee, and connects closely with our guides to wills, trusts, and guardianship and conservatorship, since a power of attorney is often the tool that helps you avoid needing the latter altogether.

A power of attorney is a legal document where one person (called the principal) gives another person (called the agent, or sometimes the attorney-in-fact) the authority to make decisions or take action on their behalf. Despite the name, the agent doesn’t have to be an actual attorney, it can be a spouse, an adult child, a trusted friend, or anyone else the principal chooses. Depending on how it’s written, a power of attorney can cover financial matters, healthcare decisions, or both.
Since this area comes with its own vocabulary, here’s a quick reference for the terms you’ll run into.
The person granting the authority, that’s you, if you’re the one signing the document.
The person receiving the authority to act on the principal’s behalf.
A power of attorney that doesn’t take effect immediately, it “springs” into effect only once a specific triggering event happens, usually the principal’s incapacity.
A power of attorney that doesn’t take effect immediately, it “springs” into effect only once a specific triggering event happens, usually the principal’s incapacity.
A power of attorney specifically covering medical decisions, sometimes called a healthcare proxy.
The act of canceling a power of attorney while the principal still has the capacity to do so.
Grants broad authority over financial and legal matters.
Grants authority over a specific task only, like selling a particular piece of property.
Remains effective even if the principal becomes incapacitated, this is what most people actually want for estate planning purposes.
Only becomes effective once a specific event occurs, typically the principal’s incapacity.
Covers financial, business, and legal matters, like banking, bill payment, and property transactions.
Covers medical decision-making specifically.
Depending on how it’s drafted, a power of attorney can authorize an agent to handle things like:
Banking and financial transactions.
Buying, selling, or managing real estate.
Paying bills and managing household expenses.
Filing and handling taxes.
Managing investments and retirement accounts.
Managing investments and retirement accounts.aOperating or managing a business.
Applying for government benefits on the principal’s behalf.
Making healthcare decisions, if it’s a healthcare power of attorney.
Handling legal claims or litigation-related decisions, in some cases.
The document can be as broad or as narrow as the principal wants, it’s entirely customizable to fit the actual need.
The principal has to have legal capacity at the time they sign, meaning they understand what they’re doing and what authority they’re granting.
The document has to meet Tennessee’s formal requirements, including proper signing and, generally, notarization.
The agent’s authority begins based on the document’s terms, either immediately upon signing, or later, if it’s a springing power of attorney.
The agent has to act within the scope of authority granted, and generally owes the principal a fiduciary duty.
Third parties, like banks and financial institutions, are generally required to accept a valid power of attorney.
The power of attorney ends upon the principal’s death, a valid revocation, or a specific end date or event named in the document itself.
It has to be in writing.
It has to be signed by the principal, while they have legal capacity to do so.
Notarization is generally required or strongly recommended.
It has to include specific “durable” language if you want it to remain valid through incapacity.
A healthcare power of attorney may have its own specific form requirements, separate from a financial power of attorney.
These two terms get confused a lot, so here’s the key distinction.
Durable
Effective immediately upon signing, and it stays effective even if the principal later becomes incapacitated. Most estate planning attorneys recommend this approach, since it avoids any delay or dispute over whether the triggering event has actually happened.
Springing
Doesn’t take effect right away, it only “springs” into effect once a specific condition is met, usually a determination of incapacity. While this might sound appealing, it can create real practical problems, since proving the triggering event has occurred sometimes requires medical documentation or even court involvement, right when quick action is needed most.
Most people end up needing both of these, since they cover completely different areas. A financial power of attorney authorizes an agent to handle money, property, and legal matters, banking, bills, taxes, real estate, and similar issues. A healthcare power of attorney authorizes an agent to make medical decisions if the principal can’t communicate or decide for themselves, everything from routine treatment decisions to more serious end-of-life care questions. You can name the same person as your agent for both, or different people, depending on who you trust most for each type of decision.
At that point, authority shifts to whoever’s handling the estate, typically an executor, not the former agent.
As long as they still have the capacity to do so.
Named in the document.
Which can happen in situations involving fraud, abuse, or improper execution.
Can a Power of Attorney Be Revoked? Yes, as long as the principal still has legal capacity, they can revoke a power of attorney at any time. This generally involves putting the revocation in writing and making sure the agent, along with any banks or institutions that had been relying on the original document, are properly notified that it’s no longer valid.
These two are closely related, but they work very differently.
Power of Attorney
Proactive and voluntary. You choose your agent and the scope of their authority while you still have capacity to make that decision.
Conservatorship
Reactive and court-imposed. It generally only becomes necessary when someone has already become incapacitated without a power of attorney in place, requiring a court process to appoint someone to act on their behalf instead.
This is exactly why setting up a power of attorney in advance matters so much, it lets you choose who acts for you and how, rather than leaving that decision to a court later. Our guide to guardianship and conservatorship in Tennessee covers that process in more detail.
Here’s roughly what the process looks like, step by step.
Financial, healthcare, or both, broad or limited.
Pick someone you genuinely trust to act in your best interest.
For most people, durable is the more practical choice.
This helps make sure it meets Tennessee’s requirements and actually accomplishes what you intend.
Following the correct formalities is what makes the document usable when it’s actually needed.
Your agent, and potentially your bank or healthcare providers, should have access to a copy.
Major life changes should prompt a review to make sure your power of attorney still reflects your wishes and your chosen agent.
