How to Get Power of Attorney in Missouri: Step-by-Step

Getting power of attorney in Missouri is not a court process. You do not need a judge's approval, a lawyer's signature, or any government filing to create a valid POA. It is a private legal document that the principal --- the person granting authority --- executes voluntarily while they still have mental capacity.

Here is the process from start to finish.

Step 1: Decide Which Type of POA You Need

Missouri law requires separate documents for financial and healthcare authority:

Financial Durable Power of Attorney (RSMo Chapter 404): Authorizes your agent to manage bank accounts, pay bills, file taxes, sell property, and handle business transactions. Must include statutory durability language so it survives your incapacity.

Healthcare Durable Power of Attorney (RSMo Sections 404.800--404.872): Authorizes your agent to consent to or refuse medical treatment, choose care facilities, and make end-of-life decisions. Can be paired with a living will that specifies your preferences on life-prolonging procedures.

Most families need both. A healthcare POA without a financial POA leaves no one authorized to pay the medical bills. A financial POA without a healthcare POA leaves no one authorized to approve the treatment.

Step 2: Choose Your Agent

Your agent (also called attorney-in-fact) must be someone you trust completely. Missouri law does not restrict who can serve as an agent --- it does not need to be a family member, a Missouri resident, or a licensed professional. However:

• Choose someone who is organized, responsive, and geographically accessible. An agent in another state may struggle to appear at Missouri banks or recorder offices in person.
• Name a successor agent in case your first choice is unable or unwilling to serve.
• For healthcare, your agent cannot also be your treating physician or their employee.

Step 3: Draft the Documents

The documents must include:

For financial POA:

• The principal's full legal name and the agent's full legal name
• The durability clause required under RSMo Section 404.705.1(2) --- without it, the POA terminates at incapacity
• Specific grants of authority for each category of transactions (banking, real estate, taxes, investments)
• Any "hot powers" you want to grant under RSMo Section 404.710 (gifts, beneficiary changes, trust amendments) --- these are void unless explicitly listed
• Limitations on the agent's authority, if any

For healthcare POA:

• The principal's full legal name and the healthcare agent's full legal name
• Specific instructions on life-prolonging procedures, artificial nutrition and hydration, and organ donation
• Whether you grant the agent the "right of sepulcher" (authority over funeral and burial decisions under RSMo Section 404.822)

Step 4: Execute and Notarize

Financial POA execution: The principal signs in front of a notary public. Witnesses are not legally required under Chapter 404, but adding two witnesses significantly reduces the chance of bank rejection. If the POA covers real estate transactions, it must be recorded with the county recorder of deeds where the property is located.

Healthcare POA execution: The principal signs in the presence of either a notary public or two disinterested adult witnesses. Witnesses cannot be the healthcare agent, cannot be related to the principal by blood or marriage, and cannot be healthcare providers or facility employees.

Recording fees: Missouri charges $24 for the first page and $3--$5 per additional page at the county recorder's office. Non-standard formatting (margins under 3/4 inch, type under 8-point) triggers a $25 penalty under RSMo Section 59.310.

Step 5: Distribute Copies and File with Institutions

This is the step most people skip, and it causes the most problems later:

• Banks and investment firms: Deliver the notarized POA in person while the principal is present and competent. Ask the institution to place it on file. Some banks also require you to sign their internal POA form --- bring the statutory POA as your primary authority.
• Healthcare providers: Register the healthcare POA with the Missouri Advance Health Care Directives Registry through the Department of Health and Senior Services.
• County recorder: Record the financial POA if it covers real estate. Record any beneficiary deeds at the same time.
• Keep originals safe: Store the original documents in a fireproof location the agent can access without you.

What You Cannot Do with a POA

A power of attorney is a lifetime document only. It terminates instantly at the principal's death. After death, authority shifts to the executor named in the will or to the personal representative appointed by the probate court.

A POA agent also cannot override the principal's wishes while the principal is still competent. The principal retains full authority to act on their own behalf and can revoke the POA at any time, in writing or by executing a new one.

The Missouri Power of Attorney Kit provides both the financial and healthcare POA templates with the required durability language, a bank submission checklist, and a step-by-step signing protocol for notarization.
