If you are an adult, you almost certainly do need a power of attorney. It is the document that lets someone you choose pay your bills, manage your accounts, or make medical decisions if illness or injury leaves you unable to do those things yourself. Without one, your family’s only route to that same authority is a court proceeding that takes months and costs thousands. The document itself costs a few hundred dollars and an afternoon.
What a Power of Attorney Does
A power of attorney is a legal document in which you (the “principal”) authorize another person (your “agent”) to act on your behalf. The authority can be as broad as running your entire financial life or as narrow as signing one set of closing papers while you are out of the country. You decide the scope.
Your agent is a fiduciary. That means they are legally required to act in your interest rather than their own, keep records of what they do with your money, and never mix your funds with theirs. Using your assets for personal benefit without permission written into the document is a breach of that duty.
One boundary to know up front: a power of attorney ends the moment you die. It does not replace a will. While you are alive but incapacitated, the POA governs. After death, your will (or, if you have none, a court-appointed administrator) takes over. You need both documents; neither substitutes for the other.
When You Need One
Some situations push a power of attorney from “should have” to “need now.”
- Planning for incapacity. Strokes, accidents, and cognitive decline arrive without warning. A durable POA lets your chosen person step in immediately, without waiting on a court.
- Aging parents. If you are already helping a parent with money or medical appointments, a POA formalizes that arrangement while the parent still has the mental capacity to sign. Once capacity is gone, it is too late.
- Travel or military deployment. Extended absences create documents that need signing and accounts that need managing. A limited POA covers the specific tasks.
- Business ownership. A sole proprietor or small business owner who is temporarily unable to work can watch an entire operation stall. A POA lets a trusted person sign contracts, pay employees, and keep the business running.
- A specific transaction. Closing on real estate, handling one investment account, or dealing with a legal matter you cannot attend to in person are all reasons for a targeted, limited POA.
The single hard requirement is mental competence at the moment you sign. That is why waiting is the wrong strategy. No attorney can create a valid POA for someone who no longer understands what they are signing.
The Cost of Not Having One
If you become incapacitated without a POA, your family’s only option is to petition a court for guardianship (personal decisions) or conservatorship (financial decisions). Every part of the process is burdensome.
A petition has to be filed. The incapacitated person often has to be examined by medical professionals. One or more hearings follow, and the family waits for a judge’s decision. The timeline typically runs several months. During that stretch, no one has legal authority to pay your bills, access your accounts, or make medical decisions beyond emergency care.
The costs stack up. Filing fees, attorney fees, medical evaluations, and hearing expenses all come with the initial appointment. Attorney fees alone can run hundreds of dollars per hour. Many states then require ongoing costs after appointment: annual accountings, sometimes prepared by an accountant or attorney, plus bonding requirements for conservators in some jurisdictions. The total easily reaches several thousand dollars up front, with recurring costs every year the arrangement continues.1Social Security Administration. GN 00602.040 – Guardianship Fees
The proceedings are public, so anyone can look up the details of your finances and medical condition in court records. And the person the court appoints might not be who you would have picked. Family disagreements over who should serve are common and add their own legal bills and their own damage. The final call belongs to a judge who has never met you, applying a best-interest standard that may not track what you would have wanted.
A POA created while you are healthy costs a small fraction of any of this, stays private, and puts your chosen person in charge instead of leaving the decision to a stranger in a robe.
The Two Documents Most People Need
Most adults benefit from two separate powers of attorney: one for money, one for medical decisions.
Financial Power of Attorney
A general financial POA gives your agent broad authority over your financial life: bank accounts, bill paying, investments, taxes, real estate. A limited financial POA restricts the agent to a specific task or period, like closing on a house while you are overseas.
Healthcare Power of Attorney
A healthcare POA, sometimes called a healthcare proxy, authorizes your agent to make medical decisions when you cannot communicate your own wishes. It is a different document from a living will, which spells out specific treatments you do or do not want in advance. The healthcare POA covers the situations you cannot anticipate, such as whether to consent to a surgery after an unexpected accident. Most estate planning attorneys recommend both.
Make It Durable
This is the detail that trips people up. A standard (non-durable) POA stops working the moment you become incapacitated, which is exactly when you need it. A durable POA stays in effect through your incapacity. In roughly 30 states that have adopted the Uniform Power of Attorney Act, durability is the default unless the document says otherwise. If you are creating a POA for incapacity planning, confirm in writing that it is durable.
Choosing an Agent
Trustworthiness matters more than financial sophistication. Your agent will have access to your accounts, your medical records, or both. An honest person who asks a CPA for help is safer than a savvy person who cuts corners.
Beyond trust, think about the practical side. Is the person willing to serve? Close enough geographically to walk into a bank branch when needed? Healthy and likely to be available? Do they understand your values well enough to make medical decisions you would recognize as yours?
Name at least one successor agent in the document. If your first choice cannot serve when the moment comes, a named successor keeps you out of court.
What a Standard POA Will Not Cover
A standard POA does not automatically work with every federal agency. Two in particular have their own systems, and this catches people off guard.
The IRS requires its own Form 2848 to authorize someone to represent you before the agency. Your representative also has to be eligible to practice before the IRS, such as an attorney, CPA, or enrolled agent. A general POA from your estate plan will not let someone call the IRS or access your tax records on your behalf.2Internal Revenue Service.

The Social Security Administration does not recognize a power of attorney for managing benefits at all. Treasury Department policy is that a POA cannot be used to negotiate federal payments, including Social Security or SSI checks. To help someone with their benefits, you have to apply separately to be appointed their “representative payee” through the SSA’s own process. Holding a POA for the same person does not give you authority over those benefits until the SSA appoints you.3Social Security Administration.

How to Actually Get One
Creating a POA is straightforward compared to what happens if you skip it.
You must be mentally competent when you sign. Most states require notarization, and even the states that do not technically require it effectively do in practice, because banks and other institutions will not honor an un-notarized document. Some states also require one or two witnesses. Using both notary and witnesses adds protection against future challenges.
Attorney fees for a single POA typically run a few hundred dollars nationally, more in major metropolitan areas. Many attorneys offer estate planning packages that bundle a financial POA, a healthcare POA, a living will, and sometimes a basic will for a combined fee. Online legal services are cheaper, though a complicated financial picture or a blended family usually justifies personalized advice.
After signing, give your agent a copy. If the POA covers real estate, some jurisdictions require recording it with the county recorder’s office. Provide copies to your bank, your brokerage, and your doctor’s office before you need the document used. Institutions are far more cooperative when they have had time to review a POA in advance than when they see it for the first time in a crisis.
