Updated August 3, 2026. Quick answer: Must be signed by the principal (or by another individual in the principal’s conscious presence, at the principal’s direction). Notarization is NOT stated as mandatory for basic validity – instead, acknowledgment before a notary public creates a legal presumption that the signature is genuine. No witness requirement of any kind is stated.. This state puts a form in its statute. A power of attorney here is durable by default — it survives incapacity unless it says otherwise.

What decides whether the document is valid
Must be signed by the principal (or by another individual in the principal’s conscious presence, at the principal’s direction). Notarization is NOT stated as mandatory for basic validity – instead, acknowledgment before a notary public creates a legal presumption that the signature is genuine. No witness requirement of any kind is stated. Get this wrong and the document is not merely weak — it may be void, and you will find out at the moment somebody needs to use it.
Who may not witness: none stated (no witnesses are required) This is the condition that most often fails in practice, because the people in the room are usually the people with an interest.
The statutory form
Idaho sets out a form in its statute at Idaho Code § 15-12-301, but does not publish a free ready-to-use copy. Using the statutory form generally means transcribing it from the statute.
Durability — the point most people get wrong
Here a power of attorney is durable by default: it keeps working after the principal loses capacity unless the document says it should not. That is the opposite of the historical rule and it is why old advice about needing magic words can mislead.
Why a springing power often fails when it is needed, and why durable is usually the better default.
If a bank refuses it
Idaho addresses this by statute: Yes – Idaho Code § 15-12-120: a person must accept an acknowledged power of attorney or request the agent’s certification/a translation/an opinion of counsel within 7 business days of presentation, and must accept within 5 business days after receiving requested documentation. Wrongful refusal is subject to a court order compelling acceptance and liability for reasonable attorney’s fees and costs, subject to listed exceptions (no ordinary business relationship, conflict with federal law, actual knowledge of termination, good-faith belief of invalidity, etc.).
What the form does not solve
- Social Security will not accept it. No power of attorney works there — a representative-payee application is the only route.
- It has to be signed while capacity is intact. The day that closes, the alternative is a court.
- Name a successor agent. A document whose only named agent has died or declined does nothing — how to choose when there is no obvious person.

If the free form does not fit your situation
This state puts a form in its statute but does not publish a free filled-in copy, so you are transcribing statutory text either way.
