Revoking a Power of Attorney in Missouri: Legal Steps to Fire a Fraudulent Agent

Current as of: September 30, 2026 Power of Attorney & Healthcare Directives Missouri
Revoking a Power of Attorney in Missouri requires formal written notice. If your agent is stealing or mismanaging funds, you must immediately sign a Revocation of Power of Attorney, notify all financial institutions, and record the document with the county to legally terminate their authority.

A Power of Attorney (POA) grants immense financial authority to another person. While most agents act responsibly, a rogue agent can drain bank accounts, sell property, and ruin your credit in a matter of weeks. In Missouri, the law requires an agent to act in your best interest, but when they violate that trust, tearing up your copy of the POA is not enough to stop them. You must take affirmative, legally binding steps to fire them.

If you suspect an agent is engaging in theft or elder abuse, immediate action is required. We strongly encourage you to find a local probate or estate litigation attorney in our US Lawyer Directory to help you execute a formal revocation and recover stolen assets.

Understanding the Agent's Fiduciary Duty in Missouri

Under Mo. Rev. Stat. § 404.714, any person acting as an attorney-in-fact (the agent) owes a strict fiduciary duty to the principal. This means they must act in good faith, keep your money separate from theirs, and avoid conflicts of interest. The legal precedent set in In re Estate of Lambur, 397 S.W.3d 54 (MO Court of Appeals 2013) clearly demonstrates that Missouri courts will hold agents liable for self-dealing and using a principal's funds for personal gain. If an agent breaches this duty, you have every right to terminate their authority under Mo. Rev. Stat. § 404.717.

Legal Steps to Revoke in Missouri

Whether you live in Kansas City, Springfield, or St. Louis, the procedure to legally strip an agent of their power requires specific documentation and broad communication.

Step 1: Draft and Notarize a Formal Revocation

You cannot simply call the agent and fire them verbally. You must execute a written document explicitly stating that you are revoking the previous POA. Your lawyer will draft a formal written Revocation of Power of Attorney pursuant to Mo. Rev. Stat. § 404.717. You must sign this document in front of a Missouri Notary Public. Once signed, send a copy to the fraudulent agent via Certified Mail with a return receipt so you have proof they were notified of their termination.

Step 2: Notifying Financial Institutions in Missouri

The most critical step is stopping the bleeding. A bank will continue to allow the agent to withdraw money until they are officially notified of the revocation. Immediately hand-deliver or overnight mail the notarized Revocation of Power of Attorney to every bank, brokerage firm, and life insurance company where you hold accounts. You should also instruct the banks to freeze the accounts temporarily or change the account numbers to prevent unauthorized ACH transfers.

Step 3: Recording a Revocation with the County Recorder of Deeds

If your rogue agent tries to sell your house or take out a mortgage in your name, title companies will check the county land records. To stop real estate fraud, you must record your revocation document in the county where you own property. For example, if you own a home in Jackson County, you must file the document with the Jackson County Recorder of Deeds, Kansas City. If you own a farm in Greene County, file it with the Greene County Recorder of Deeds, Springfield. Recording it places the public on formal legal notice that the agent has been fired.

Step 4: What to Do if the Agent Refuses to Step Down

Sometimes, an agent will ignore the revocation, claiming you lack the mental capacity to fire them. When this happens, you must take the fight to Probate Court. Your attorney can file an adversary petition for discovery of assets pursuant to Mo. Rev. Stat. § 473.340 with the local court, such as the St. Louis County Circuit Court, Probate Division, Clayton. This legal action forces the rogue agent to stand before a judge, surrender all stolen funds, and provide a full accounting of every penny they spent.

How Much Does it Cost in Missouri?

Acting quickly saves you from catastrophic financial losses. Here are the typical costs associated with firing an agent and revoking a POA:

Legal ActionEstimated Cost (USD)
Drafting & Notarizing Revocation Document$150 - $350
Recording Fee (County Recorder of Deeds)$24 for the first page, $3 for each additional page
Probate Court Petition to Recover Assets$2,500 - $7,500+ (Retainer for litigation)

How Long Does the Process Take?

A formal Revocation of Power of Attorney can be drafted, notarized, and delivered to your bank on the exact same day, instantly cutting off the agent's access to your cash. Recording the document with the county typically takes 1 to 3 days to appear in the public registry. If you have to sue the agent in Probate Court to recover stolen assets, that litigation can take 6 to 12 months to reach a final judgment.

Frequently Asked Questions (FAQ)

Do I need to prove the agent stole money to revoke the POA?

No. If you have the mental capacity to make decisions, you can revoke a Power of Attorney at any time, for any reason, without having to prove fraud or mismanagement to a judge.

What happens if the agent already sold my car?

If the agent sold your property before you formally revoked the POA, the sale is generally legal, but the agent must give you the money. If they kept the profits, you can sue them for breach of fiduciary duty to recover the funds.

Will the bank refund money the agent stole?

Usually not. If the bank had a valid Power of Attorney on file and you had not yet notified them of the revocation, the bank is legally protected. You must pursue the fraudulent agent directly to get your money back.

Can I revoke a POA if I have been diagnosed with dementia?

It depends on the severity of the diagnosis. To revoke a POA, you must have 'contractual capacity' (the ability to understand what you are doing). If a doctor determines you have lost capacity, a family member must petition the Probate Court for guardianship to remove the rogue agent.
