You need a power of attorney because if illness or injury ever leaves you unable to manage your own affairs, it is the only thing that lets someone you trust step in without a court getting involved. Without one, no one, not even your spouse or adult children, has automatic authority to pay your bills, manage your accounts, or direct your medical care. Your family’s only option becomes a guardianship or conservatorship proceeding, which is public, slow, and expensive, and the judge, not you, decides who ends up in charge.
What Happens If You Don’t Have One
This is the part most people underestimate. If you become incapacitated without a power of attorney in place, your family has to petition a court to appoint a guardian or conservator over your affairs. That process takes time, often months, during which your bills pile up and medical decisions may sit in limbo.
The costs are not small. Guardianship and conservatorship proceedings are public, so your financial and medical details become part of the court record. Attorney fees and court costs typically run into the thousands of dollars, all paid from your assets, and the court oversight continues year after year through annual reporting requirements. A power of attorney, by contrast, generally costs a few hundred dollars to have an attorney draft, with more complex situations running higher. Keeping control in your hands and out of a courtroom is the central reason to have the document at all.
There is also the question of who ends up making decisions. In a guardianship, that is the judge’s call. The person appointed may not be the person you would have chosen, and may not know you well enough to make the choices you would have made.
Why a Durable Power of Attorney Is the Point
The scenario a power of attorney is built for is the one where you cannot speak for yourself. A stroke, a serious car accident, or a condition like Alzheimer’s disease can take away your ability to manage your own affairs with little or no warning. If you already have a power of attorney in place when that happens, your agent can step in immediately to pay the mortgage, manage bank accounts, coordinate medical care, and keep your life running.
For that to work, the document has to be durable. “Durable” means it stays in effect even after you lose mental capacity. Under the Uniform Power of Attorney Act, which more than 30 states have adopted, a power of attorney is presumed durable unless the document expressly says it ends upon incapacity. If your document is not durable, your agent loses all authority the moment you become incapacitated, which is precisely when you need help the most.
It’s Not Only for Worst-Case Scenarios
A power of attorney is also a practical tool for situations where you simply cannot be present. Closing on a house while traveling internationally. Helping an aging parent with finances when you need someone local to handle paperwork while you are out of town. A limited power of attorney can cover a single transaction or a defined window of time.
Military families rely on this heavily. Service members deploying overseas routinely grant a power of attorney to a spouse or family member so that someone back home can handle banking, manage property, make decisions about their children’s schooling, and deal with unexpected issues that cannot wait.1Navy JAG Corps.

What Your Agent Can Be Allowed to Do
You control exactly what your agent can and cannot do. Powers of attorney fall into two broad categories, financial and healthcare, and you can create one document or separate documents for each.
Financial Authority
A financial power of attorney can authorize your agent to handle tasks like:
- Accessing your bank accounts and paying bills
- Filing your tax returns
- Managing investments
- Buying or selling real estate
- Running a business
- Applying for government benefits such as Medicaid or veterans’ benefits
You can grant these powers broadly or limit them to specific accounts, transactions, or time periods. A well-drafted document spells out exactly which powers the agent has so there is no ambiguity when the agent needs to act.
Healthcare Authority
A healthcare power of attorney, sometimes called a healthcare proxy, lets your agent make medical decisions if you cannot communicate your own wishes. That includes consenting to or refusing treatments, choosing doctors and facilities, deciding whether to admit you to a hospital or nursing home, and accessing your medical records. This authority typically kicks in only when a physician determines you are unable to make your own decisions.
A healthcare power of attorney is not the same as a living will. A living will states your specific wishes about end-of-life treatment, such as whether you want life-sustaining measures if you are terminally ill. A healthcare power of attorney appoints a person to make decisions on your behalf, including situations a living will does not cover. Most estate planning attorneys recommend having both, since the living will guides your agent’s choices while the power of attorney gives that person the legal authority to carry them out.
When to Put One in Place
Now, or as soon as you can get to it. The one requirement every type of power of attorney shares is that you must be mentally competent to create it. You have to understand what a power of attorney is, what powers you are granting, and who you are granting them to. Once you have lost that capacity, it is too late. You cannot sign a power of attorney from a hospital bed after a serious brain injury, and your family cannot sign one for you. At that point, guardianship is the only path forward.
Every adult over 18 should have at least a durable financial power of attorney and a healthcare power of attorney. This is not just for elderly people or the wealthy. A 25-year-old in a car accident needs someone to pay rent and make medical decisions just as urgently as a 75-year-old with dementia. The document sits quietly in a drawer until it is needed, and when it is needed, nothing else can replace it.
It is also worth revisiting the document after any major life change. Divorce, a falling-out with the person you named, or the death of your agent are all reasons to sign a new one. Some states automatically revoke a former spouse’s authority after divorce, but you should not rely on that alone. Name at least one backup agent in your original document so that if your first choice is unable or unwilling to serve when the moment comes, your plan still works.
