I have signed a durable power of attorney -- can I change my mind?
Once you've signed a durable power of attorney, it's still your power of attorney. You have the right to revoke it, resend it, change it, destroy it any time. There is one legal requirement, you still have to have capacity to do so. You can't destroy it if you no longer have legal capacity. Since it's your power of attorney and perhaps one of most important planning tools you can use, it can absolutely be modified by you at any time after you've issued it
