To get power of attorney for someone, that person must be mentally competent when they sign, and the process runs in a predictable order: decide which type of POA fits their situation, pick an agent (and a backup), draft or complete the form, and execute it with the witnesses and notarization your state requires. For a straightforward case, it’s an afternoon’s work. If the person has already lost the capacity to understand what they’re signing, a POA is no longer an option, and the path forward is court-appointed guardianship instead.
Start With Mental Capacity
A power of attorney is a voluntary grant of authority. The person giving it, called the principal, has to understand what the document does, who they’re giving authority to, and what powers they’re handing over. If a doctor or a judge later concludes the principal didn’t have that understanding on signing day, the POA can be thrown out.
Two practical consequences follow. First, don’t wait. Healthy adults set up POAs precisely because capacity can vanish quickly after a stroke, an accident, or a fast decline. Second, if the principal is elderly or showing early cognitive changes, get a physician’s letter confirming competency dated the same day as the signing. That single piece of paper heads off most future challenges.
Financial POA and Healthcare POA Are Two Different Documents
Most people need two POAs, not one. A financial POA covers money: bank accounts, bill payments, investments, tax matters, and property transactions. A healthcare POA, sometimes called a healthcare proxy or medical power of attorney, covers medical decisions: treatment choices, hospital admissions, medications, and end-of-life care. Keeping them separate means the doctor never sees the brokerage statements and the financial advisor never sees the medical chart.
You can name the same person as agent on both, and many families do. If you name different agents, choose people who talk to each other easily. A decision to move the principal into long-term care is a medical call with immediate financial consequences, and the two agents will need to coordinate.
Pick the Right Type
Within each category, POAs come in several forms. Getting the wrong one is where families most often stumble.
- Durable power of attorney. Stays in effect even if the principal becomes incapacitated. This is the workhorse for long-term planning. In roughly 30 states that have adopted the Uniform Power of Attorney Act, a POA is presumed durable unless the document says otherwise.
- General (non-durable) power of attorney. Grants broad authority but ends automatically if the principal loses capacity. Useful for short-term situations, like handling affairs during a long trip.
- Limited power of attorney. Grants authority for a specific task or period, such as closing on a house while the principal is abroad. It ends when the task is done or the time runs out.
- Springing power of attorney. Lies dormant until a triggering event, usually incapacitation certified by one or more physicians. The appeal is that the agent has no authority unless it’s actually needed; the drawback is that getting the certification takes time, and some banks are reluctant to accept springing POAs because verifying the trigger is more work.
For most families planning ahead, a durable POA for finances paired with a separate healthcare POA covers the most ground with the least friction.
Choose an Agent and a Successor
The agent is a fiduciary. That means the law requires them to act in the principal’s best interest, avoid conflicts of interest, stay within the authority granted, and keep reasonable records of every transaction. Breaching those duties can bring personal liability, court removal, and, in bad cases, criminal charges for financial exploitation.
Trustworthiness matters more than financial sophistication. An honest person can hire an accountant. A dishonest person with an MBA will find creative ways to move money. Look for someone who is organized enough to keep records, available enough to handle time-sensitive matters, and willing to take on what can be a demanding role. Family members are the usual choice. When family dynamics are complicated or no relative fits, a professional fiduciary is worth considering.
Name at least one successor agent. The successor steps in if the original agent dies, becomes incapacitated, resigns, or otherwise can’t serve, and generally holds the same authority. Without a named successor, the POA becomes useless the moment the original agent drops out, and if the principal has lost capacity by then, the family is heading to court for a guardianship.
Decide What the Agent Can Do
A POA can be as broad or as narrow as the principal wants. Common categories of authority include:
- Banking and financial transactions: accessing accounts, writing checks, managing investments.
- Bill payment and debt management: paying routine bills, negotiating with creditors, handling insurance claims.
- Real estate: buying, selling, or refinancing property, managing rentals, paying property taxes.
- Government benefits: applying for or managing Social Security, Medicare, Medicaid, or veterans’ benefits.
- Legal and business matters: hiring attorneys, filing lawsuits, running a business interest.
Be specific. “Handle all financial affairs” sounds convenient but gives the agent room to do things the principal never intended. Overly narrow language, on the other hand, leaves the agent stuck when something unexpected comes up. The workable middle is granting categories of authority in enough detail that a bank or title company can see what’s covered, with a catch-all clause for matters the principal didn’t anticipate.
Gifting authority deserves its own attention. Unless the POA explicitly permits it, most states bar the agent from making gifts of the principal’s assets. If the principal wants the agent to continue charitable giving or make family gifts for tax planning, spell it out with dollar limits.
Prepare the Document
Three routes are common, and the right one depends on how complicated the principal’s situation is.
State statutory forms are available in most states through the legislature’s website, the courts, or legal aid organizations. These fill-in-the-blank forms track the format state law approves, which makes banks and other institutions more likely to accept them. They work well for straightforward cases.
Online legal services offer customizable templates with guided questions, generally running $35 to $150, and produce a document tailored to your state. Reasonable middle ground when the principal wants more flexibility than a statutory form allows but doesn’t need an attorney.
An attorney is the right call when the principal has significant assets, business interests, property in multiple states, or complicated family dynamics. Fees for a standalone POA typically run $150 to $500, and the cost is often lower when bundled with a will or trust. Much of the value is in the conversation about what the principal actually needs, which is where DIY options fall short.
Whatever route you choose, gather the full legal names and current addresses of the principal and every named agent, a clear description of the powers being granted, and any conditions or limits on those powers. For a springing POA, specify exactly what event triggers authority and how that event gets verified.
Sign, Witness, and Notarize
Every state requires the principal to sign. What else the state requires varies. Most states require notarization, many also require one or two adult witnesses who watch the principal sign, and some require both. An improperly executed POA can be rejected outright, so check your state’s rules before the signing or let an attorney handle execution.
Witnesses generally cannot be the named agent, and some states bar anyone who benefits under the POA from serving as a witness. The notary confirms the principal’s identity and that the signature is voluntary. These formalities exist to guard against fraud and to make later challenges harder. Skipping them where they’re technically optional is a false economy.
Distribute Copies and Record if Property Is Involved
Once the document is signed and notarized, make several certified copies. The agent needs one. Every financial institution the agent will deal with should have one on file. For a healthcare POA, give copies to the principal’s doctors and hospital. Keep the original somewhere secure but accessible; a fireproof safe at home works, while a safe deposit box can backfire if the agent needs the document to get into the box.
If the POA grants authority over real estate, most states require it to be recorded with the county recorder or register of deeds in every county where the principal owns property. Recording gives public notice that the agent can act on property matters. Without it, a title company may refuse to process a sale or refinance. Recording fees vary by county but generally run $30 to $75.
Getting Banks and Other Institutions to Accept the POA
A valid POA doesn’t guarantee that a bank or brokerage will accept it without pushback. Financial institutions worry about liability if the document turns out to be forged, revoked, or the product of undue influence. Some have their own proprietary POA forms and will press agents to complete those instead.
In states that have adopted the Uniform Power of Attorney Act, an institution that unreasonably refuses a valid POA can be ordered by a court to accept it and can be held liable for the agent’s attorney fees. Most of those states allow a reasonable review period, often around seven business days, before a refusal is treated as unreasonable. An institution can still legitimately refuse if it has reasonable cause to question the document, suspects abuse, or would violate federal law by accepting.
A few practical steps cut down on rejection headaches. Present the POA in person at each institution before you actually need to use it, so any problems surface while the principal can still help resolve them. Bring a certified copy and the principal’s identification. Some banks will take a few days to route the document through their legal department. If an institution insists on its own form, having the principal sign that too costs nothing and avoids a standoff when time is short.
Build in Safeguards Against Abuse
POA abuse is one of the most common forms of elder financial exploitation. The Consumer Financial Protection Bureau recommends that the principal require the agent to report regularly to another trusted person on the financial transactions they make.1Consumer Financial Protection Bureau. What Is a Power of Attorney (POA)? Smart safeguards to build into the document or the process include:
- Require periodic accounting to a named third party (another family member, an accountant, or an attorney) on a quarterly or annual basis.
- Restrict or prohibit gifts to the agent or others unless specifically authorized, with dollar caps.
- Name co-agents for large transactions, requiring two signatures above a set dollar amount.
- Tell people the POA exists. Inform other family members, financial advisors, and the principal’s attorney that the POA is in place and who the agent is. Secrecy is what enables abuse.1Consumer Financial Protection Bureau. What Is a Power of Attorney (POA)?
The principal can revoke the POA at any time while still mentally competent. Revocation should be in writing, notarized, and delivered to the agent and to every institution that has a copy. If the original was recorded with a county recorder, record the revocation there too.
Know When the POA Ends
A durable or general POA takes effect the moment the principal signs. A springing POA takes effect only when its triggering event occurs. A POA ends in any of these circumstances:
- Death of the principal. All powers terminate immediately. The agent has no authority to pay funeral expenses or access accounts for final bills. Authority passes to the executor named in the will or an administrator appointed by the probate court.
- Revocation by a competent principal, in writing to the agent.
- Incapacitation, if the POA is not durable.
- Divorce. In most states, if the agent is the principal’s spouse, divorce automatically ends the agent’s authority. If you’re going through a divorce and your soon-to-be-ex is your agent, don’t wait for the decree; execute a new POA with a different agent.
- Completion of purpose, for a limited POA.
- Agent resignation or incapacity with no named successor.
Tax Matters Need a Separate IRS Form
A standard durable POA does not authorize someone to deal with the IRS on the principal’s behalf. To represent someone before the IRS, the representative must file IRS Form 2848, Power of Attorney and Declaration of Representative, and the representative must be eligible to practice before the IRS, which generally means an attorney, CPA, enrolled agent, or certain other authorized tax professionals.2Internal Revenue Service. About Form 2848, Power of Attorney and Declaration of Representative If the principal only needs someone to receive tax information without representing them in disputes, the IRS has a simpler form (Form 8821) for that purpose.
If the Person Has Already Lost Capacity
This is often what drives the search in the first place. A parent has had a stroke. A spouse has advanced dementia. Someone has to manage their affairs, and there is no POA.
The hard truth: you cannot create a power of attorney for someone who has already lost the mental capacity to understand and sign the document. A POA requires voluntary, informed consent. Any POA signed by someone who can no longer comprehend it is invalid and can be challenged in court.
The alternative is court-appointed guardianship, called conservatorship in some states. It involves filing a petition, providing medical evidence of incapacity, and attending a hearing where a judge decides whether the person needs a guardian and who should serve. The court typically appoints an independent attorney to represent the incapacitated person’s interests and may order an independent medical evaluation.
Guardianship is slower, more expensive, and more intrusive than a POA. Attorney fees, court costs, medical evaluations, and the court-appointed attorney’s fees can easily total $3,000 to $10,000 or more, and the process can take several months. Once appointed, the guardian answers to the court on an ongoing basis, with regular reporting and sometimes prior court approval for major decisions. A POA, by contrast, is a private arrangement with no court involvement at all.
The practical lesson is the same one estate planning attorneys have been repeating for decades: set up the power of attorney while the person is healthy and clearly competent. Waiting until capacity is in doubt makes the whole thing harder, more expensive, and much less certain.
