A power of attorney can last for an indefinite time. If you prefer, you can state that it will expire on a specific date or when a certain event occurs.
If no specific end date or event is listed, a power of attorney may end when any of the following events happens:
The principal dies
The principal is incapacitated (nondurable only)
The principal revokes it
The principal and agent divorce or annul their marriage
The purpose of the power of attorney expires
Death of the agent (if there is no successor agent or co-agent)
If your agent or a third party are unaware of the fact that your power of attorney has ended, they usually will not be liable for continuing to act on it. Imagine, for example, that your agent sells your property to a third party after your revocation. If the third party has a good faith belief that your power of attorney is still valid, they might not have to return the property. This is why it’s so important to inform your agent and anybody you do business with about the revocation or expiration of your power of attorney. This will help to avoid any future hassles.
