Power of attorney (POA) is a powerful legal document that allows one person to act on behalf of another in financial, legal, or medical matters. This responsibility is often entrusted to someone reliable—usually a spouse, adult child, or close friend—particularly when the person granting the power (known as the “principal”) is no longer able to make decisions independently. But while the authority granted under a POA is broad and vital, it doesn’t last forever.

What Is a Power of Attorney?
A power of attorney is a legal document through which a principal designates another person, called the “agent” or “attorney-in-fact,” to act on their behalf. Depending on the type and scope of the POA, this authority can range from making simple financial transactions to making life-or-death healthcare decisions.
POAs are used in a variety of situations: someone may appoint an agent to manage finances while traveling abroad, assist with ongoing healthcare decisions as they age, or manage affairs due to illness or disability. However, it's critical to understand that the powers given are not indefinite. The expiration of a POA can occur naturally through legal provisions or be triggered by specific events.
Types of Power of Attorney
There are several types of power of attorney, each with different scopes and durations. Knowing which type is in place helps clarify when it will expire:
- General Power of Attorney
A general POA grants broad authority to the agent to act on behalf of the principal in a wide range of matters—banking, real estate, taxes, and more. However, it becomes invalid if the principal becomes incapacitated. This is commonly used for temporary situations. - Durable Power of Attorney
A durable POA remains in effect even if the principal becomes mentally or physically incapacitated. This is a common choice in estate planning. The word “durable” must be explicitly stated in the document; otherwise, the POA will expire upon incapacity. - Springing Power of Attorney
A springing POA only becomes active under conditions defined in the document—most commonly, when the principal becomes incapacitated. Medical proof is often required to “trigger” this type of POA. - Medical (or Healthcare) Power of Attorney
This POA gives the agent authority to make healthcare decisions for the principal if they become unable to do so. It typically activates when a doctor determines the principal lacks decision-making capacity and expires upon death or when the principal regains capacity. - Limited (or Special) Power of Attorney
A limited POA is restricted to a specific task or time frame—for example, allowing someone to sign real estate documents while the principal is out of the country. It expires once the task is completed or at a specified end date.
When Does Power of Attorney Expire?
There are several common circumstances under which a POA ends. The timing and reason for expiration depend on the type of POA and the situation surrounding the principal and agent.
1. Death of the Principal
The most definitive and universal expiration of a power of attorney occurs upon the death of the principal. Regardless of the type—general, durable, or medical—all POAs are automatically terminated when the principal dies. At this point, the estate enters probate (if required), and the executor or personal representative named in the will assumes legal authority over the deceased’s affairs.
This is one of the most misunderstood aspects of POAs: the agent does not have any power after the death of the principal. If you are named as both POA and executor, you must switch roles accordingly and follow the terms of the will and probate laws.
2. Revocation by the Principal
A principal can revoke a POA at any time, provided they are mentally competent. This revocation should be done in writing and communicated clearly to the agent and any institutions or individuals the agent has interacted with (e.g., banks, medical providers).
3. Specified Expiration Date or Event
Some POAs have a set expiration date or are created for a specific purpose. For example, a limited POA might be valid only during the duration of a real estate transaction or while the principal is overseas. Once the event or date passes, the POA automatically expires.
4. Incapacity (for Non-Durable POAs)
General and limited POAs that are not explicitly marked as “durable” expire if the principal becomes incapacitated. This includes cognitive decline due to illness, accidents, or other health conditions.
5. Completion of Purpose
If a POA is created for a particular task—such as signing legal documents or closing a business deal—it expires when that task is completed.

The Importance of Keeping POA Documents Updated
Because a POA is so integral to managing a person’s affairs, it’s essential that these documents be reviewed regularly. Life circumstances change—marriages end, agents move or pass away, and medical needs evolve. Updating the POA ensures that the right person is empowered to act and that the document remains valid. Additionally, some banks, hospitals, and other institutions may be wary of very old POAs. Keeping your documentation current can help prevent unnecessary delays or legal hurdles during a crisis.
When planning ahead, it’s wise to consult an estate attorney to ensure your POA documents are correctly drafted, durable if necessary, and in line with your current needs. The best way to make sure your wishes are honored is to ensure the legal structure around them is rock-solid—and timely.
