As the principal of your Power of Attorney, you have the authority to cancel it. You can rescind your Power of Attorney at any time, as long as you are competent and notify your attorney. This is true even if the Power of Attorney has a specified end date.
However, it’s important to note that an Enduring Power of Attorney remains in effect even if you’re mentally incapacitated. Once you are lacking mental capacity, you’re no longer able to revoke an Enduring POA.
It’s also important to note that courts have the authority to revoke a Power of Attorney in certain situations, including circumstances where an attorney is deemed unfit to act.
