Updated August 3, 2026. Quick answer: Notarization (acknowledgment) required; no witnesses required. Must be signed by the principal, or in the principal’s conscious presence by another individual (not a prospective agent) directed by the principal, and acknowledged before a notary public or other authorized individual.. This state publishes a free official form, linked below. A power of attorney here is durable by default — it survives incapacity unless it says otherwise.

What decides whether the document is valid
Notarization (acknowledgment) required; no witnesses required. Must be signed by the principal, or in the principal’s conscious presence by another individual (not a prospective agent) directed by the principal, and acknowledged before a notary public or other authorized individual. 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 requirement exists); the named agent specifically may not notarize the principal’s signature (Iowa Code §633B.105). This is the condition that most often fails in practice, because the people in the room are usually the people with an interest.
The free official form
Iowa publishes a form at no cost: the official Iowa power of attorney form. For a straightforward appointment this is usually all you need, and there is no reason to pay for a copy of it.
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
Iowa addresses this by statute: Yes, with deadline and sanction: a person presented with an acknowledged POA must accept it, or request certification/translation/opinion of counsel, within 7 business days of presentation; if such a request is made, must accept within 5 business days of receiving the response. May not demand a different/additional POA form, subject to listed exceptions. Wrongful refusal exposes the refuser to a court order compelling acceptance and liability for damages plus reasonable attorney fees/costs (suit within 1 year). Iowa Code §633B.120.
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
Use the official form above first — it is free, it is written to satisfy this state’s own statute, and for a straightforward appointment it is usually all that is needed. Software is worth paying for when the situation outgrows a fixed form: co-agents, successor agents, limits on gifting, or a bank that has already given you trouble.
