Signed with two adult witnesses and a notary acknowledgment. This is the belt-and-suspenders execution that satisfies every state's requirement, and it is what this document uses until the rule is confirmed for your state.
Pending verification. These health and disposition rules are drawn from general practice and have not yet been confirmed against Iowa statutes, so your documents are prepared with two witnesses and a notary acknowledgment — the strictest combination any state imposes. Confirm with a licensed attorney in Iowa before signing.
Two competent adult witnesses should sign in the presence of the testator and of each other, followed by a notary acknowledgment for the self-proving affidavit.
Signing day in Iowa, step by step
Bring: final documents printed single-sided and unstapled; blue or black ink pens; government photo identification for you and every witness. You will also need the number of adult, disinterested witnesses your state requires and a commissioned notary public (bank, shipping store, title company or mobile notary).
Before signing day
- 1Confirm you may sign. You must be at least 16 to make a will and 18 to sign healthcare documents in Iowa, and you must be of sound mind and signing voluntarily.
- 2Arrange witnesses. Arrange 2 witnesses for your will. Iowa expects disinterested witnesses, so use adults who receive nothing under your plan.
- 3Book a notary. Notarization of the trust is strongly recommended in Iowa, and the notary also completes the self-proving affidavit for your will. Bring photo ID for everyone.
- 4Print the final set. Print every document single-sided on paper. Iowa does not recognize an electronic signature on a will, so it must be signed on paper.
Will and revocable living trust
- 1Sign the revocable living trust. Sign the trust as grantor and as trustee in front of the notary. Governing statute: Iowa Code 633A.2102.
- 2Declare and sign the will. State aloud that the document is your will and that you are asking the witnesses to witness it, then sign at the end in their presence.
- 3Witnesses sign. Your 2 witnesses sign in your presence and in each other's presence and print their names and addresses. Governing statute: Iowa Code 633.279(2).
- 4Complete the self-proving affidavit. Immediately afterward, you and the witnesses swear to the affidavit before the notary, who signs and seals it. This lets the court accept the will without calling your witnesses.
Healthcare, HIPAA and disposition documents
- 1Sign the healthcare power of attorney and living will. Sign in front of 2 witnesses. Your agent, relatives by blood or marriage, heirs and employees of your treating provider may not serve as witnesses. Statute: Iowa Code 144B.
- 2Sign the HIPAA authorization. Sign and date the HIPAA authorization; no witnesses are required under federal law. Iowa requires express authorization for mental health and psychiatric records, substance use disorder treatment records (42 C.F.R. Part 2), HIV/AIDS testing and treatment records, genetic testing results records, which your form includes.
- 3Sign the final disposition instructions. Sign in front of 2 witnesses and have it notarized.
- 4Sign the durable financial power of attorney. Have the financial power of attorney notarized even if the statute is silent; banks and county recorders will insist on it.
After signing
- 1Store originals and distribute copies. Keep the signed originals somewhere safe and accessible, tell your successor trustee where they are, and give copies to your healthcare agent, physician and hospital.
- 2Fund the trust. Retitle real estate, accounts and business interests into the trust and update beneficiary designations.
