Who Can Override a Power of Attorney? Understanding the Checks and Balances

A power of attorney (POA) is a legal document that grants an individual the authority to act on behalf of another person in various legal and financial matters. However, there are instances when someone may need to override or challenge the authority granted by a POA. In this blog, we delve into who holds the power to override a power of attorney and the checks and balances involved.

1. The Principal

The individual who initially grants the power of attorney, known as the principal, is the primary authority when it comes to revoking or overriding the POA. As long as the principal retains the mental capacity to make decisions, they can revoke the POA at any time. This can be done by creating a new POA that explicitly revokes the previous one or by providing written notice to the agent and relevant parties involved.

2. Legal Guardian or Conservator

In situations where the principal is no longer capable of making sound decisions due to incapacity, a court may appoint a legal guardian or conservator. This legal guardian or conservator has the authority to override the existing POA. This is typically done to protect the best interests of the principal when the agent’s actions are not in their best interest.

3. The Agent’s Misconduct

If the agent appointed by the POA is not acting in the best interests of the principal or is involved in misconduct, their authority can be challenged or overridden. Misconduct may include financial mismanagement, conflicts of interest, or failing to execute their duties as outlined in the POA document.

4. Third Parties

While not a direct override, third parties such as banks, medical providers, or financial institutions can refuse to honor a power of attorney if they believe it is not valid, suspect fraud, or perceive that the agent is not acting in the principal’s best interests. Their refusal to accept the POA effectively limits the agent’s authority in specific transactions.

5. Expiration or Specific Conditions

Some POAs have specific conditions or expiration dates. When these conditions are met or the expiration date passes, the agent’s authority comes to an end. For example, a limited POA for a specific transaction will expire once that transaction is completed.

6. State Laws and Regulations

State laws and regulations play a crucial role in determining who can override a power of attorney and under what circumstances. These laws may differ from one jurisdiction to another, so understanding your state’s specific legal framework is essential.


A power of attorney grants significant authority to the appointed agent, but it is not without limitations. Various parties, including the principal, legal authorities, and third parties, hold the power to override or challenge a POA under specific circumstances. These checks and balances exist to protect the interests of the principal and ensure that the agent’s authority is exercised in their best interest. Understanding these dynamics is crucial for those involved in the execution and oversight of power of attorney arrangements.
