# Iowa will signing requirements

How many witnesses, who shouldn't witness, and what the statute says about the self-proving affidavit, handwritten wills, electronic wills, remote witnesses and the minimum age.

✓ New Jersey commissioned notary, no. 50244803, insured for errors and omissions. [See the credentials](/about/credentials)

**Short answer.** 2 witnesses. A self-proving affidavit is sworn before an oath officer such as a notary. Handwritten wills: no. Remote witnesses: yes.

## At a glance

Witnesses

Two witnesses, who sign at the testator's request in the presence of the testator and each other.

"witnessed, at the testator's request, by two competent persons"

Witness age

The self-proving affidavit form says the witnesses were 16 or older.

"the witnesses were sixteen years of age or older"

Beneficiary as witness

The will stays valid, but unless two disinterested witnesses also signed, an interested witness loses whatever the will gives beyond what that witness would get with no will.

"No will is invalidated because attested by an interested witness"

Self-proving affidavit

Allowed at signing or any later date, before a person authorized to administer oaths and take acknowledgments. A self-proved will can be admitted without witness testimony.

"before a person authorized to administer oaths and take acknowledgments under the laws of this state"

Handwritten wills

Not recognized unless witnessed: every will, to be valid, must be signed and declared before two witnesses (Iowa Code 633.279). The only exception the section names is for wills made under another state's law (633.283).

"All wills and codicils, except as provided in section 633.283, to be valid, must be in writing"

Electronic wills

Not authorized, per Nolo's Iowa page (updated September 2025).

"Iowa currently doesn't allow e-wills"

Remote witnesses

Presence can be physical or electronic, as long as the witness and testator can see and hear each other. Counterparts signed in different places are allowed.

"any manner, physical or electronic, in which the witness and testator can see and hear"

Minimum age

Of full age: at least 18, or ever married (Nolo, citing Iowa Code 633.264 and 633.3).

"are at least 18 years old, or"

## Signing day here

- **Witnesses to bring:** Bring 2 witnesses, each at least 16.
- **Notary and the self-proving affidavit:** Have a notary or another officer who can administer oaths there for the self-proving affidavit. The statute names that officer rather than notaries by name.
