A financial power of attorney is a document that lets you name someone to handle money matters for you if you cannot handle them yourself. In Missouri it is governed by the Durable Power of Attorney Law of Missouri, found at Section 404.700 RSMo and the sections that follow. Set it up right while you are healthy, and someone you trust can pay your bills and manage your accounts the day you get sidelined. Skip it, and your family may end up in probate court asking a judge for permission to do the same thing.
Here is the part that trips people up: not every power of attorney keeps working after you lose capacity. In Missouri, only a durable one does. Get that word and the right language into the document, or the whole point falls apart.
What a financial power of attorney actually does
A financial power of attorney has two roles. You are the “principal,” the person granting the authority. The person you name is the “attorney in fact,” sometimes called your agent. The agent is not a lawyer; the term just means the person you authorize to act for you.
You decide how much authority to hand over. It can be broad enough to cover nearly every money decision you could make yourself, or narrow enough to cover one account or one transaction. You are in control of the scope when you sign.
This is a financial tool. It does not cover medical decisions. Those go in a separate health care directive and health care power of attorney. If you want a plain-English walkthrough of how these documents fit together, our overview of the Missouri legal toolkit lays out the full set.
Durable is the word that matters
A plain power of attorney ends the moment you become disabled or incapacitated. That is exactly backward from what most people want. You want the document to kick in when you are down, not shut off.
Missouri fixes this with the durable power of attorney. Under Section 404.705 RSMo, the authority you grant is not terminated if you become wholly or partially disabled or incapacitated, but only if three things are true. The document has to be denominated a “Durable Power of Attorney.” It has to include a statement in substance that your agent’s authority does not end if you become disabled or incapacitated. And it has to be signed.
Miss any of those, and you may be left with a document that dies right when you need it most. This is not a place to download a random form and hope for the best.
What powers your agent has
Under Section 404.710 RSMo, you can grant your agent general powers to act on your behalf across all lawful subjects, or you can limit those powers to specific subjects you spell out. General powers are broad. They let your agent step into your financial shoes for the subjects you name.
But Missouri draws a hard line around a set of high-stakes actions. Some powers do not come along with a general grant. They only exist if the document expressly authorizes them. Under Section 404.710, that list includes the power to make or revoke gifts of your property, to disclaim a gift or inheritance, and to make an anatomical gift, among others.
Why the fence? These are the powers that could be used to move your money out from under you or reshape who inherits it. Missouri wants that authority granted on purpose and in writing, not slipped in by accident. If you want your agent to be able to make gifts, for example as part of a long-term care plan, the document has to say so in plain terms.
Your agent is not free to do whatever they want
Naming an agent is not handing over a blank check. Under Section 404.714 RSMo, an agent who chooses to act has a legal duty to act in your interest and to avoid conflicts of interest that would get in the way. Your agent is supposed to follow your instructions and act for you, not for themselves.
That duty matters. If an agent misuses the authority, the law gives you and your family a basis to hold them accountable. It is one reason the person you name matters more than almost any other choice in the document.
When it starts, and when it ends
You choose when the authority begins. Some Missouri powers of attorney are effective the moment they are signed. Others are written to become effective only when you actually become disabled or incapacitated; these are often called springing powers. Section 404.705 recognizes both, including durable language written for a power that becomes effective later.
It ends in the ways you would expect. You can revoke it while you still have capacity. It ends at your death. And Section 404.717 RSMo covers modification and termination of the power as between you and your agent. If your situation changes, you can change or cancel the document; you are not locked in.
Name a backup
Life happens to your agent too. The person you name might move, get sick, or pass away before you do. Section 404.723 RSMo deals with successor attorneys in fact and the delegation of powers, and it also addresses a court’s role for incapacitated or disabled persons.
The practical takeaway is simple: name at least one successor agent. If your first choice cannot serve, your backup steps in and you avoid a gap that could send your family to court.
How to set one up in Missouri
- Pick your agent, and a backup. Choose someone who is honest, organized, and available. This is the single most important decision in the document.
- Decide how much authority to grant. Broad general powers, or a narrow list of specific subjects. Decide on purpose which express powers, like gifting, you want to include.
- Decide when it starts. Effective immediately, or springing into effect only if you become incapacitated.
- Use durable language. Make sure the document is denominated a durable power of attorney and includes the statutory durable statement, so it survives incapacity.
- Sign it correctly. Missouri requires the document to be signed, and notarization is standard practice so banks and other third parties will honor it.
- Get it in the right hands. Give copies to your agent and keep the original somewhere your agent can reach it when the time comes.

Frequently asked questions
Is a financial power of attorney the same as a will?
No. A power of attorney works while you are alive and unable to act for yourself. A will only takes effect after you die. They do different jobs, and most people need both.
Does my agent have to be a lawyer?
No. “Attorney in fact” just means the person you authorize to act for you. It is usually a spouse, adult child, or other trusted person, not a lawyer.
Can my agent give away my money or change who inherits?
Only if you expressly grant that power. Under Section 404.710 RSMo, powers like making or revoking gifts do not come with a general grant. They exist only if the document spells them out.
Does a Missouri power of attorney have to be notarized?
Section 404.705 RSMo requires the document to be signed for the durable authority to hold. Notarization is not the only formality that can matter, and in practice it is standard so that banks and other institutions will accept it. Have yours prepared correctly rather than guessing.
What happens if I never set one up?
If you lose capacity without a power of attorney, no one automatically has legal authority over your finances. Your family may have to ask a probate court to appoint a guardian or conservator, which costs time and money and puts a judge in the middle of your affairs.
Can I change or cancel it later?
Yes. As long as you have capacity, you can revoke or modify the document. Section 404.717 RSMo addresses modification and termination between you and your agent.
Does a college student need one?
Often yes. Once a young adult turns 18, parents lose legal authority over their finances and records. We cover this in detail in our guides on power of attorney forms for college students and powers of attorney for Kirksville students.
