Who Can Override a Power of Attorney in Missouri?
Key Takeaways
- A competent principal can revoke or amend a power of attorney at any time without needing court approval.
- Written notice of revocation should go to the agent, banks, and healthcare providers to take effect in practice.
- Family members cannot override a power of attorney alone; only a court can remove an agent.
- Requesting an accounting from the agent is often a practical first step before asking a court to remove them.
- Courts can appoint a guardian or conservator to take over an incapacitated principal’s decisions.
Missouri families dealing with a difficult agent often ask the same question first: who can override a power of attorney? An experienced Estate Planning Lawyer in St. Louis, Missouri, at TdD Attorneys at Law can help a family determine whether the answer is revocation, court action, or both. Under Missouri law, only a competent principal or a Missouri court acting through a guardianship or conservatorship proceeding may formally override a valid power of attorney, and family members cannot cancel one on their own without court approval.

Primary Ways to Override a Power of Attorney in Missouri
The principal, the person who created the power of attorney, keeps broad control over the document as long as mental capacity remains intact, and the law lets courts step in when that control breaks down. The question of who can override a power of attorney starts with the principal’s own authority: as long as the principal is competent, they may revoke or amend the document at any time, for any reason, without needing anyone else’s permission.
RSMo § 404.717 sets out how that authority ends, and the principal can deliver oral or written notice to the attorney-in-fact, the person named to handle the principal’s affairs, or file a written notice of termination with the recorder of deeds in the principal’s county of residence. Notifying the agent alone is often not enough in practice: a bank or healthcare provider that never receives notice may still honor the agent’s authority in good faith, so sending that same written notice directly to financial institutions and healthcare providers closes the gap. A new, properly drafted power of attorney also supersedes the prior instrument automatically once it expressly revokes the earlier one or conflicts with its terms.
Court Intervention, Guardianship, and Third-Party Challenges
Family members who suspect an agent is mismanaging finances or ignoring the principal’s wishes cannot revoke a power of attorney on their own, but they still have options. RSMo § 404.727 allows the principal, an adult family member, or another interested person to petition Missouri’s probate court to determine whether the principal is disabled or incapacitated and to request an accounting from the attorney in fact. Requesting that accounting first is often the more practical starting point, since it builds a documented record before a family asks the court to suspend or remove an agent.
With enough early evidence that the principal is incapacitated and the agent has broken, or may break, the duty to act in the principal’s best interest, the court can suspend the agent’s authority and name someone else to act in the meantime. A formal incapacity finding lets the court go further and remove the agent outright, and a guardianship or conservatorship gives a court-appointed guardian that same power.
Generic online power of attorney templates rarely include the successor designations or safeguards these situations call for, which leaves families exposed to costly court battles like these.

Missouri Intestate Succession and Estate Risks Without Proper Planning
Once a court suspends or terminates an agent’s authority, the principal’s financial affairs often fall under direct court supervision until a successor or guardian steps in, which can slow down bill payments and property management during an already stressful period. That planning gap resurfaces at death, when a family without a coordinated estate plan may find assets passing under Missouri’s intestate succession rules, the state’s default rules for dividing an estate when someone dies without a valid will, rather than the principal’s actual wishes.
A properly executed power of attorney, paired with a will or trust that names clear beneficiaries and successor agents, closes that gap and gives a family one unified plan instead of conflicting documents for the probate court to resolve.
