Iowa Will Requirements at a Glance
Here are the exact rules for making a valid will in Iowa:
| Minimum age to make a will | 18 (Iowa Code § 633.3 defines “full age” as 18, or younger if married; § 633.264 requires “full age” and sound mind to make a will) |
| Witnesses required | 2 (Iowa Code § 633.279(1) requires two competent witnesses who sign in the presence of the testator and in the presence of each other; witnesses must be at least 16 years old per § 633.280) |
| Notarization required | NO — notarization is not required for a valid Iowa will, but a notary is needed if you want to attach a self-proving affidavit under § 633.279(2), which allows the will to be admitted to probate without live witness testimony |
| Handwritten (holographic) will allowed | NO — Iowa does not recognize holographic (handwritten, unwitnessed) wills; a handwritten will is valid only if it meets all standard execution requirements under § 633.279, including two witnesses |
| Self-proving affidavit available | YES — under Iowa Code § 633.279(2), an attested will may be made self-proved at the time of execution or at any later date by the testator’s acknowledgment and the witnesses’ sworn affidavits, all made before a notary public or other person authorized to administer oaths; a self-proved will may be admitted to probate without testimony of attesting witnesses under § 633.293 |
| Statutory will form | NO — Iowa does not provide an official statutory fill-in-the-blank will form; the Iowa State Bar Association offers some legal forms for healthcare directives but not a statutory last will and testament; you may draft your own will meeting § 633.279 requirements or consult a licensed attorney |
What a Iowa Will Does (and Doesn’t Do)
a valid Iowa will lets you name a personal representative (executor) to manage your estate, name a guardian for your minor children, direct how your probate assets are distributed, make specific bequests of personal or real property, and set conditions or create testamentary trusts for beneficiaries
What a Iowa will does NOT control: a will does not control assets that pass outside probate — this includes life insurance proceeds with a named beneficiary, retirement accounts (IRAs, 401(k)s) with a named beneficiary, payable-on-death (POD) or transfer-on-death (TOD) accounts, property held in joint tenancy with right of survivorship, and assets already placed in a living trust
Oral wills in Iowa: NO — Iowa does not recognize oral (nuncupative) wills; § 633.279 requires all wills to be in writing with no exception for deathbed or military situations
How to Update or Revoke a Iowa Will
a will may be amended by executing a codicil, which must meet the same signing and witnessing requirements as the original will under § 633.279; a will may be revoked by (1) canceling or destroying it by the testator’s act or direction with intent to revoke, where the cancellation is witnessed in the same manner as making a new will,
or (2) executing a subsequent valid will (Iowa Code § 633.284); a revoked will cannot be revived except by re-execution or incorporation by reference in a new will or codicil

Other Iowa will-making rules: (1) Iowa allows remote witnessing — witnesses may sign via real-time audio-video technology if they can see and hear the testator, with signatures combined into the final document (§ 633.279); (2) a beneficiary named in the will may serve as a witness without invalidating the will,
but an interested witness forfeits any bequest exceeding what they would have received without the will unless the will is also attested by two disinterested witnesses (§ 633.281); (3) Iowa permits wills validly executed under the laws of a foreign state or country to be admitted to Iowa probate even if they do not meet Iowa’s specific execution requirements (§ 633.283);
(4) a will may be deposited with the clerk of court for safekeeping during the testator’s lifetime (§§ 633.286–633.287)

Understanding Iowa Estate Planning
Getting started with Iowa estate planning is the single best gift you can give your family. A valid Iowa will lets you decide who inherits, name an executor, and name a guardian for your children — instead of leaving it to a default state formula.
When people look into Iowa estate planning, the real answer comes down to the state’s execution rules: your age, the number of witnesses, and whether you make it self-proving. If any part of Iowa estate planning is unclear, your state court’s self-help center can point you to the official forms and resources.
