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 is required when the principal signs personally; the statutory form’s optional block for a principal who cannot sign has the notary affix the signature in the presence of the principal and a witness (Idaho Code § 15-12-301). This state puts a form in its statute. A power of attorney here is durable by default — it survives incapacity unless it says otherwise.

Idaho power of attorney form: what the statute says
Each line is quoted from the Idaho statute itself.
- Execution. Idaho Code 15-12-105: “A power of attorney must be signed by the principal or in…”
- Witnesses. The execution section above prints no witness requirement.
- Recording for real estate. Idaho Code 55-805(1): “…its execution must be acknowledged by the person executing it… or the execution must be proved and the acknowledgment or proof, certified in substantially the manner prescribed by chapter 1, title 51, Idaho Code…” This is the state’s general recording statute for land documents.
- Statutory form. Idaho Code 15-12-301: “A document substantially in the following form may be used to create…”

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 is required when the principal signs personally; the statutory form’s optional block for a principal who cannot sign has the notary affix the signature in the presence of the principal and a witness (Idaho Code § 15-12-301). 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 witness is required when the principal signs personally; see the form’s optional signing block for a principal who cannot sign, Idaho Code § 15-12-301). Where a state does bar particular people from witnessing, 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.
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. LawDepot builds a state-specific power of attorney executed under this state’s witnessing and notary rules. For a complex estate or a likely family dispute, a lawyer is the better route.

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.
