Who Can Override A Power Of Attorney (POA)? (2026)

Understanding Power of Attorney and Its Purpose

A power of attorney (POA) is a legal document that allows a person to act on your behalf in legal, financial and medical matters. Many POAs offer this even if you’re incapacitated. There are different types of POAs, including a general power of attorney, which offers broad rights to the agent acting on your behalf.

If you prefer the agent to have more limited rights, you can draft a limited power of attorney. Durable powers of attorney, on the other hand, remain in place until the death of the principal or until the POA is revoked. Other POAs you can choose include medical, special and springing POAs.

Who Has the Authority to Revoke a POA?

Who can override a power of attorney? The principal (the person who created the POA) has the authority to revoke the document at any time. They must be mentally competent, however. If the principal is incapacitated, then the courts can revoke the POA.

Valid Reasons for Revoking a POA

Revoking a POA requires demonstrating at least one of the following:

• Agent is unwilling to serve
• Agent has misused their powers
• Agent incapacity or death
• Breakdown of the relationship between agent and principal
• Desire to appoint a new agent
• Change in circumstances (moves or health improves)

In some instances, the purpose of the POA may have been accomplished. For example, if you created a POA so that the agent could sell your home, the revocation can take place once the home is sold.

Steps to Revoke or Challenge a POA

If the principal is mentally competent, the process involves drafting a revocation document, signing it, notarizing it and notifying the agent. Third parties, like banks, must also be notified of the revocation.

If the principal lacks the mental capacity to revoke the POA, family members can challenge it. You will need to gather evidence to prove that the agent has mismanaged the estate. You’ll have to file a petition with the court and request a guardian or conservator to step in.

Can a Spouse or Family Member Step In?

Yes, a family member or spouse can step in if they feel the agent is not managing their responsibilities as needed. They will have to challenge the POA in court.
