Power of Attorney
What Is a Power of Attorney?
A power of attorney (POA) is a legal document that lets you authorize someone else to act on your behalf — sign contracts, manage bank accounts, make medical decisions. It's the single most important estate-planning document for adults under 65, because it covers what happens if you become incapacitated, not just what happens when you die. Without one, your family may need a court-appointed guardian (expensive, slow, public).
The Short Answer
A POA authorizes someone (your "agent" or "attorney-in-fact") to act for you. Two types matter most: durable financial POA (handles money, bills, contracts) and healthcare POA (medical decisions). Both should be in place by age 18. Cost: $150–$400 per document from a lawyer; included in most $1,500–$3,500 estate-plan packages. The mistake people make: not having one. The second mistake: choosing the wrong agent.

The two POAs every adult should have
Durable financial power of attorney. Authorizes your agent to handle financial matters — pay bills, manage bank accounts, file taxes, sign contracts, manage real estate, deal with insurance. "Durable" means it stays in effect even if you become incapacitated.
Healthcare power of attorney (also called healthcare proxy or medical POA). Authorizes your agent to make medical decisions when you can't — choosing treatments, consenting to surgery, deciding on end-of-life care, communicating with doctors.
Both are needed. The financial POA does not authorize medical decisions, and the healthcare POA does not authorize financial matters.
Both should be paired with an advance directive (also called a living will) that states your wishes about end-of-life care, life support, and similar issues. The directive guides your healthcare agent's decisions.
And both should be paired with a HIPAA release authorizing named people to access your medical records and communicate with healthcare providers.
Durable vs. springing
Durable POA. Effective immediately upon signing and continues even if you become incapacitated. Most lawyers recommend this format because it works in every situation.
Springing POA. Becomes effective only if a triggering event occurs — typically a doctor's certification of your incapacity. Sounds safer, but causes problems in practice.
The springing POA's incapacity-certification requirement creates delays — banks, hospitals, and other institutions want to see the certification documents before honoring the POA, and getting them takes days or weeks during a crisis.
Most modern estate planning uses durable POAs paired with a trusted agent. The risk that the agent acts before you're truly incapacitated is real but typically managed by choosing the right person, not by adding the springing trigger.
Some states have specific statutory forms — California's UPOA, New York's Statutory Short Form POA, others. Using the statutory form ensures banks accept it without legal review.
Who should you name as agent?
The single most important decision. The agent has enormous authority over your money or your medical care.
Trustworthy. Not just "good with money" or "my oldest child." Someone who will act in your interests and follow your wishes.
Available. Your agent needs to be reachable when needed and willing to deal with paperwork.
Geographically reasonable. An agent across the country can do most things remotely, but local agents are easier for healthcare matters and in-person banking.
Comfortable with the role. Some people are temperamentally unsuited — they'll second-guess every decision or panic at the responsibility.
Consider age. Naming a 75-year-old parent might create the very situation you're trying to plan for. Naming a 25-year-old child means they'll need to navigate decisions they're not yet experienced with.
Name a successor. The named agent might be unavailable, decline, or need to be replaced. Name a backup.
Couples often name each other and a child or sibling as backup. Single people often name a sibling, adult child, or close friend.
Lawyers, financial advisors, and CPAs can be named — but they often charge for the service and may have conflicts.
What can your agent do?
Under a financial POA, depending on what powers are granted: pay bills, manage bank and investment accounts, file taxes, sign checks, deal with insurance claims, file lawsuits, manage real estate (sell, lease, mortgage), make gifts, manage retirement accounts, handle Social Security and Medicare matters, and operate a business.
Limits: most state POAs default to limiting the agent from making gifts or changing beneficiary designations unless the document specifically authorizes it. Adding gifting authority is sometimes necessary for Medicaid planning.
Under a healthcare POA: consent to or refuse medical treatment, choose doctors and hospitals, access medical records, make end-of-life decisions, decide on life support and resuscitation orders, authorize organ donation.
What an agent CANNOT do: change your will, vote in elections for you, perform actions specifically barred by the POA document, or act after your death (the POA terminates at death — the executor takes over).
What does a power of attorney cost?
Free DIY: state POA forms are typically available free from state bar association websites, AARP, and senior service organizations. Properly executed, they're legally valid.
Online services (LegalZoom, RocketLawyer, etc.): $35–$100 per document. Generic but functional.
Lawyer-drafted: $150–$400 per document. Custom to your situation.
Estate plan package: a full estate plan ($1,500–$3,500) typically includes durable financial POA, healthcare POA, advance directive, and HIPAA release at no separate charge.
Bank-specific POAs: many banks have their own POA forms. Some banks won't honor a generic POA and require their internal version. If you have multiple bank relationships, sign each bank's specific form too.
Periodic renewal: most lawyers recommend new POAs every 5–7 years even if nothing has changed. Older documents are sometimes treated with skepticism by banks and healthcare providers.
What goes wrong without a POA
Adult guardianship / conservatorship. Without a POA, your family may need a court-appointed guardian to handle your financial affairs and a conservator for medical decisions. The process is expensive ($5,000–$15,000+ in legal fees), slow (3–6+ months), and public.
Frozen accounts. Without a POA, banks freeze accounts when an account holder becomes incapacitated. Bills go unpaid; mortgages default; utilities get cut.
Hospital decisions delayed. Doctors need consent for treatment. Without a healthcare POA, hospitals fall back on default state-law surrogate decision-makers — typically spouse, then adult children, then parents. The default may not be who you'd choose, and disagreements among family members can paralyze decision-making.
Tax filings missed. Without authority to file taxes, returns get missed and penalties accumulate.
Real estate stuck. Without authority to sign deed paperwork, real-estate transactions stall.
Family conflict. The default decision-maker may not be the family member you trust. POAs prevent this exact scenario.
Most people who don't have POAs don't realize they need them until it's too late. The time to plan is when you're healthy.

Frequently asked questions
When does a power of attorney expire?
When you revoke it, when you die (POA terminates automatically at death), when the agent dies or resigns, when the document specifies an expiration date, or when a court invalidates it. Healthcare POAs in some states terminate when you regain capacity.
Can I change my POA?
Yes — sign a new one and notify the agent and any institutions that have the old one. Some states require recording revocations with the county. Your lawyer will handle the formalities.
What if my agent abuses the POA?
POA abuse (financial elder abuse) is a serious problem. Choose carefully. The legal remedy is to file a guardianship/conservatorship petition asking the court to appoint a different decision-maker, and to sue the agent for breach of fiduciary duty. Some states allow criminal prosecution for elder financial abuse.
Do my spouse and I need separate POAs?
Yes. Each adult needs their own POAs — the documents are personal. Couples often name each other as agent, but the documents themselves are individual.
Can a POA override a will?
No. POAs operate during your life; wills operate after your death. They don't conflict because they govern different times.
Do I need to record a POA with the county?
Required in some states for real-estate transactions; not generally required for other purposes. Your lawyer will advise based on your state and assets.
