An Idaho Durable Power of Attorney Form is designed to allow the Attorney-in-Fact to continue to act on behalf of the Principal, even if the Principal is declared incapable of making their own decisions. More often than not, this kind of agreement will only come into effect once the Principal has already been declared incapacitated. This is known as a Springing Power of Attorney Agreement.
In Idaho, a Power of Attorney agreement does not require witness and is not required to be notarized. In addition a Durable Power of Attorney agreement does not automatically become void if the Principal and Attorney-in-Fact are spouses and they are separated, so the Principal would have to voluntarily revoke it, unless they wish their former spouse to remain their Attorney-in-Fact.
