Overview
A Power of Attorney (POA) is a written legal instrument that lets one person (the principal) appoint another person (the agent or attorney‑in‑fact) to act on their behalf. POAs are fundamental in estate and financial planning because they allow trusted agents to sign documents, access accounts, manage property, and make healthcare decisions if the principal cannot or chooses not to act.
In my experience as a financial advisor, a clear, properly executed POA prevents delays, reduces the risk of family disputes, and often saves money compared with court‑appointed guardianship. I’ve seen clients avoid months of administrative obstacles simply because they had a durable POA that banks and service providers accepted.
(Authoritative guidance: see the IRS on tax representatives and Form 2848 and the Consumer Financial Protection Bureau for general consumer guidance on POAs.)

How a Power of Attorney Works
A POA is effective only if properly executed under your state’s rules. Typical requirements include:
- A written document that identifies the principal and agent and describes the authority granted.
- The principal’s signature; many states require notarization and/or one or two witnesses.
- Clear durable language if you want the authority to continue after incapacity (see below).
- Delivery of the document to third parties (banks, brokerages, healthcare providers) for recognition.
Types of POA determine when and how the agent acts. Not every institution accepts every POA form—banks, retirement plan administrators, and title companies may have their own forms or require specific language. If you need an agent to work with the IRS, the IRS Form 2848 is required to name an authorized representative for tax matters (more: https://finhelp.io/glossary/how-to-name-an-authorized-representative-with-the-irs-power-of-attorney-basics/).
Main Types of Powers of Attorney
-
Durable Power of Attorney (financial): Explicitly states that the principal’s incapacity will not terminate the agent’s authority. For example: “This power of attorney shall not be affected by the principal’s subsequent disability or incapacity.” Durable POAs are the standard for long‑term planning and elder care.
-
General Power of Attorney: Gives broad authority over financial matters but typically ends if the principal becomes incapacitated unless it’s also durable.
-
Limited (or Special) Power of Attorney: Grants authority for a specific task or period—such as completing a single real estate closing or managing a business while you travel.
-
Springing Power of Attorney: Only takes effect when a specific event occurs, usually the principal’s incapacity. Springing POAs can create proof issues because third parties must accept the triggering evidence (physician certification, court order), which can delay action.
-
Medical (Healthcare) Power of Attorney: Authorizes an agent to make medical decisions for the principal if they cannot do so. This is frequently used alongside an advance directive or living will. (See our detailed page on durable healthcare agents: https://finhelp.io/glossary/durable-power-of-attorney-for-healthcare/.)
When to Create a POA
Consider a POA when you:
- Want someone to manage finances during travel, hospitalization, or long‑term care.
- Own assets that could require immediate attention (rental properties, small business, investments).
- Have a chronic health condition or are entering older age.
- Are a business owner who needs continuity planning.
A POA is simple to set up compared with the complexity and cost of a court conservatorship or guardianship, which often becomes necessary if no agent is designated.
When to Update or Revoke a POA
Review your POA at least every 3–5 years or any time you experience major life events. Important triggers to update or revoke:
- Marriage, divorce, or death of an agent or successor agent.
- A change in your financial situation (new business, significant new assets, or relocation to another state).
- A loss of trust or a change in your relationship with the named agent.
- Changes in your health or the onset of progressive incapacity.
- New laws in your state that affect POA form or language.
To revoke a POA, the principal must be mentally competent and should execute a written revocation, notify the agent in writing, and provide copies to institutions that accepted the original POA. For IRS matters, the IRS provides specific procedures for revocation and termination of tax POAs (see https://finhelp.io/glossary/how-to-revoke-a-power-of-attorney-with-the-irs/).
Choosing an Agent: Criteria and Practical Checks
Pick an agent with these characteristics:
- Trustworthiness and shared financial values.
- Familiarity with your finances or willingness to learn.
- Availability and geographical proximity, if needed.
- Ability to keep accurate records and communicate with family members and advisors.
Professional tip from my practice: name a successor agent (or two). If your first choice is unwilling or unable to serve, a successor prevents gaps. Also, specify whether the agent’s decisions require co‑signatures, reporting to a named person, or periodic accounting.
Practical Steps to Create and Use a POA
- Decide what powers you need to grant and whether they should be durable or springing.
- Use a state‑specific form or a lawyer‑drafted document. Generic forms may omit necessary language for banks or state law.
- Sign in front of required witnesses and a notary if your state requires it.
- Provide certified copies to your agent and to institutions that will rely on the POA (banks, brokerages, mortgage servicers, healthcare providers).
- Store the original in a safe place and keep accessible copies with instructions. Consider giving your agent a certified copy or uploading it to a secure document service.
- Discuss your expectations with the agent and provide a written summary of important accounts, advisors, and passwords where possible.
Note on real estate: many states require the POA used for real estate transactions to be recorded with the county recorder; ask your closing attorney or title company.
Common Mistakes and How to Avoid Them
- Relying on a general POA that is not durable—this will terminate on incapacity in many jurisdictions.
- Selecting an agent without vetting their financial competence or reliability.
- Not informing banks, advisors, or family about the POA’s existence and location.
- Choosing a springing POA without clear triggering mechanics, which can slow urgent access.
- Failing to update a POA after major life changes.
Special Considerations: Taxes and the IRS
If your agent needs to deal with federal tax matters, the IRS requires Form 2848, Power of Attorney and Declaration of Representative, to formally recognize a representative for tax matters. Banks and financial institutions may not accept Form 2848 for non‑tax transactions—use institution‑specific forms as needed. (IRS Form 2848 info: https://www.irs.gov/forms-pubs/about-form-2848 and practical guidance: https://finhelp.io/glossary/how-to-name-an-authorized-representative-with-the-irs-power-of-attorney-basics/.)
Healthcare POAs and Advance Care Planning
A Medical Power of Attorney is distinct from a financial POA and should align with your advance directive or living will. Health systems often require separate forms and may ask for a HIPAA authorization so your agent can access medical records. Combine a medical POA with written treatment preferences to reduce conflicts during crises.

Recordkeeping, Oversight, and Abuse Prevention
Agents have a fiduciary duty to act in the principal’s best interest. Good safeguards include:
- Requiring periodic accounting to a trusted family member or advisor.
- Limiting the agent’s authority for high‑risk actions (selling primary residence, gifts to self).
- Employing a co‑agent structure where two agents must act together.
- Using a trust or a professional fiduciary for complex estates.
If you suspect agent misuse, revoke the POA (if competent), notify institutions, and consider a court petition to remove the agent. Consumer resources on protecting yourself include the CFPB’s consumer tools for estate planning (https://www.consumerfinance.gov/consumer-tools/estate-planning/power-of-attorney/).
Quick Checklist: When to Review or Update Your POA
- Every 3–5 years as a best practice
- After marriage, divorce, or death of named persons
- When you move to a different state
- When you acquire significant new assets or a business
- If you lose trust in the named agent
Final Thoughts
A properly drafted and recognized Power of Attorney is one of the most practical, low‑cost ways to preserve financial continuity and respect personal wishes. In my practice, formalizing a POA and combining it with a simple information packet for the agent is among the highest‑value steps clients take to reduce stress and legal friction for their families.
