To get power of attorney for your mom, she has to grant it to you herself, in writing, while she still has the mental capacity to understand what she’s signing. You cannot obtain a POA on her behalf or take one from her. Her role is to create the document and name you as her agent; your role is to help her choose the right type, prepare it correctly, sign it with the formalities her state requires, and deliver copies to the banks, doctors, and other institutions that will need to honor it. If she has already lost the ability to understand and make decisions, a POA is no longer possible, and the only remaining path is a court-supervised guardianship or conservatorship.
Start With Whether She Has Capacity to Sign
A power of attorney is only valid if the person creating it understands what they’re doing at the moment they sign. Your mom doesn’t need perfect health or a flawless memory. She needs to grasp three things: what a POA is, what authority she is handing over, and who she is handing it to.
A diagnosis of dementia, Alzheimer’s, or another cognitive condition doesn’t automatically disqualify her. Capacity is measured at the time of signing, not by a label in her medical chart. Someone with early-stage dementia may have stretches of full clarity, and a POA signed during one of those windows can be perfectly valid.
If there is any doubt, have her doctor perform a capacity evaluation close to the signing date. A written assessment becomes evidence that she was competent when the document was executed, which can head off later challenges from other family members or institutions. An elder law attorney can also help evaluate whether she meets the threshold. Don’t wait. Capacity can decline suddenly after a stroke, a fall, or a hospitalization, and once it is gone, the POA window closes permanently.
If She Has Already Lost Capacity
When a parent can no longer understand or sign legal documents, a power of attorney is off the table. The only remaining option is to petition a court for guardianship, which covers personal and medical decisions, or conservatorship, which covers finances. Terminology varies by state, and some states use one term to cover both roles.
Court-supervised guardianship is significantly more burdensome than a POA. The process involves filing a petition, paying court filing fees, and usually retaining an attorney. A court-appointed investigator or guardian ad litem will interview your mom and report back to the judge on whether guardianship is warranted. Total costs, including attorney fees, filing fees, and investigation costs, commonly range from a few thousand dollars to over $10,000, and the process can take weeks or months. Ongoing bond premiums and annual reporting to the court add further expense. The proceedings are also public record. All of this is why acting while your mom still has capacity saves enormous time, money, and stress.
Decide Which POA Documents She Needs
Most families caring for an aging parent need two separate documents: a financial POA covering money, property, and business matters, and a healthcare POA giving the agent authority over medical decisions. These are almost always separate forms, and many states have their own statutory versions designed to meet local requirements.
Durable vs. Springing
For an aging parent, a durable power of attorney is almost always the right choice. “Durable” means the document stays in effect even if your mom later becomes incapacitated. Without that durability language, a standard POA loses its force exactly when you need it most, because the agent’s authority is suspended the moment the principal can no longer make decisions.
A springing power of attorney doesn’t kick in until a specific triggering event, usually a doctor’s certification that the principal is incapacitated. The appeal is that your mom keeps full control of her affairs until that moment. The downside is that proving incapacity to banks and other institutions can create delays right when you need to act quickly. Many estate planning attorneys steer clients away from springing POAs for this reason, favoring a durable POA paired with a conversation about when the agent should begin acting.
Healthcare POA
A healthcare POA, sometimes called a healthcare proxy or medical power of attorney, authorizes you to make medical decisions if your mom can’t speak for herself. It works alongside a living will, which is a written statement of her treatment preferences. Ideally your mom should have both, because the living will captures her wishes and the healthcare POA gives you the standing to carry them out and make the judgment calls the living will doesn’t cover.
Once a healthcare POA is in effect and your mom is unable to make her own decisions, you become her “personal representative” under federal privacy law, which gives you the same right to access her medical records as she would have.1U.S. Department of Health and Human Services. Does Having Health Care Power of Attorney Allow Access to Patient Medical Records Under HIPAA Some doctor’s offices still ask for a standalone HIPAA form, so it’s worth signing one anyway to avoid friction.
Choose the Agent (and a Successor)
Your mom doesn’t have to choose you, and you should both think carefully about whether you’re the best fit. Proximity matters. The agent handling finances will need to visit banks, sign documents, and deal with institutions in person. If you live across the country and a sibling lives nearby, the sibling may be the more practical choice for day-to-day financial management, even if you’re the one pushing to get the paperwork done. Trustworthiness is non-negotiable, but financial literacy matters too. If her affairs include investment accounts, rental property, or business interests, the agent needs the ability to manage those responsibly or the willingness to hire professionals who can.
Naming a successor agent is one of the most commonly skipped steps and one of the most important. If the primary agent dies, becomes incapacitated, or simply can’t serve, the successor takes over without anyone needing to go back to court. Without a successor, your family could end up in the guardianship process even though your mom planned ahead.
Prepare the Document
A power of attorney document should include:
- Your mom’s full legal name and address as principal.
- The full legal name and address of the agent she is appointing.
- Names and addresses of one or more successor agents.
- The specific powers being granted, which can range from broad authority over all financial matters to narrowly defined tasks such as selling a particular piece of property or managing a single bank account.
- A clear statement that the POA remains effective if she becomes incapacitated.
- Any special provisions, such as whether the agent can make gifts from her assets, handle retirement accounts, or engage in transactions that benefit the agent personally.
Many states publish statutory short-form POA documents, and using your state’s official form is the simplest way to ensure the document meets local requirements. These forms are typically available on the state legislature’s website or through your county clerk’s office. An elder law or estate planning attorney can also draft a customized document, which is worthwhile if your mom’s situation involves complex assets, blended family dynamics, or specific concerns about how the authority should be limited. Attorney fees for drafting a POA typically range from a few hundred dollars to around $500 or more, depending on complexity and location. Free and low-cost help is available for qualifying individuals through local legal aid societies and Area Agencies on Aging.
Sign It Correctly
Execution requirements differ by state, and getting them wrong can invalidate the entire document. Most states require the principal to sign in front of a notary public, who verifies her identity and confirms she is signing voluntarily. Many states also require one or two adult witnesses to be present alongside the notary, particularly for healthcare POAs or durable financial POAs. Some states accept either notarization or witnesses; others require both.
Witnesses should be disinterested parties. They shouldn’t be named as agents in the document and ideally shouldn’t be family members or anyone who stands to benefit from the principal’s decisions. The notary, the witnesses, and your mom all need to be in the same room at the same time. Mobile notary services can come to her home or care facility if she has difficulty traveling, usually for an additional fee.
Don’t cut corners here. A POA that’s missing a required witness signature or notary acknowledgment can be rejected by a bank or challenged in court years later. If you’re using your state’s statutory form, follow its instructions exactly. If an attorney is drafting the document, they will typically coordinate the signing.
Distribute the POA and Get It Accepted
A signed POA sitting in a drawer doesn’t help anyone. After execution:
- Store the original safely but accessibly. A fireproof safe at home works better than a bank safe deposit box, since getting into the box may require the very authority the document grants.
- Deliver copies to financial institutions early. Don’t wait until a crisis to walk into your mom’s bank with a POA. Present it while things are calm, and ask the bank to place it on file. Many banks have their own internal POA acceptance forms or agent affidavits they’ll ask you to complete, typically requiring you to swear that the POA hasn’t been revoked, that the principal is still alive, and that no guardian has been appointed. Ask what the bank requires up front and bring everything in one visit.
- Give copies to healthcare providers. Her primary care physician, specialists, and any hospital system she uses should have a copy of the healthcare POA on file.
- Record the POA with the county if real estate is involved. If it grants authority to buy, sell, or mortgage real property, many states require or strongly recommend recording it with the county recorder or clerk where the property is located. An unrecorded POA may be rejected by a title company at closing.
When you act under the POA, sign in a way that makes the representative relationship clear, such as “Jane Smith, as agent for Mary Smith.” Don’t sign your mom’s name as if you were her. The distinction protects both of you and puts third parties on notice that you’re acting under legal authority.
When an Institution Refuses to Honor the POA
Banks and other financial institutions sometimes refuse to honor a valid power of attorney, and it is one of the most frustrating parts of the process. Common reasons include the document being “too old,” not being on the institution’s preferred form, or staff being unfamiliar with how POAs work. Many states have laws penalizing institutions that unreasonably refuse a properly executed POA, and the Uniform Power of Attorney Act, adopted in over 30 states and the District of Columbia, includes provisions protecting agents against arbitrary rejection.2Consumer Financial Protection Bureau. POA Rejected by Bank or Credit Union – What Can I Do If you hit a wall, ask to speak with the institution’s legal or compliance department, provide a certified copy rather than a photocopy, and be prepared to cite your state’s acceptance statute. An attorney letter can also move things along quickly.
What You’re Agreeing to as Agent
Accepting a power of attorney isn’t just permission to act. It is a legal obligation to act carefully and honestly. As agent, you owe your mom fiduciary duties, meaning you must put her interests ahead of your own in every transaction. This is where people get into serious trouble, sometimes without realizing it.
Your primary duties include acting loyally and in her best interest, managing her assets with reasonable care, keeping her property separate from your own, and maintaining records of every transaction you handle on her behalf. Record-keeping is especially important. If anyone ever questions your management, whether a sibling, a court, or a government agency, your records are your defense. Keep receipts for every payment, document every withdrawal, and track every bill you pay from her accounts. Sloppy records are one of the most common reasons agents face legal liability, even when they haven’t done anything intentionally wrong.
An agent generally cannot transfer the principal’s money or property to themselves. Even if you are confident your mom would approve, “she would have wanted me to have it” is not a legal defense. If the POA document explicitly authorizes the agent to make gifts, including gifts to the agent, then limited self-dealing may be permissible. Otherwise, moving her funds to your own account, paying your personal bills from her money, or “borrowing” from her assets is a breach of fiduciary duty that can result in personal liability and even criminal charges. When in doubt, don’t do it, and get legal advice before making any transaction that benefits you personally.
How the POA Can End
A power of attorney isn’t permanent. Your mom can revoke it at any time, as long as she still has capacity. Revocation should be in writing, and she should notify the agent directly, ideally by certified mail, so there is proof the agent received the notice. She should also notify every institution that has a copy on file, because a bank that doesn’t know about the revocation may continue to honor the old POA in good faith. Signing a new POA does not automatically cancel a previous one unless the new document explicitly says so.
A power of attorney also terminates automatically when the principal dies. Many families miss this. The moment your mom passes away, your authority as agent ends completely. You cannot use the POA to access her accounts, pay her bills, or handle her property after death. Authority then shifts to the executor or personal representative named in her will, or to an administrator appointed by the probate court if she didn’t have a will. If your family is doing estate planning, the POA and the will should be prepared together so the transition is clean.
Other events that typically end a POA include divorce, since many state laws automatically revoke a spouse-agent’s authority when the marriage ends, a court order terminating the POA, or the appointment of a guardian or conservator by a court.
