Idaho recognizes attested wills, holographic wills, and harmless-error wills

Idaho Code — Execution; Witnessed Wills; Holographic Wills

Idaho Code § 15-2-502

What the rule says

Idaho provides three pathways to a valid will under the UPC framework:

Attested wills (Idaho Code § 15-2-502)

A valid Idaho attested will requires:

1. A writing. 2. The testator's signature. 3. Two competent witnesses.

Holographic wills (Idaho Code § 15-2-503(2))

An Idaho holographic will is valid if material provisions are in the testator's handwriting and signed.

Harmless-error doctrine (Idaho Code § 15-2-503)

Defective documents can be probated with clear and convincing evidence of testamentary intent.

Self-proving affidavits

Idaho recognizes self-proving affidavits under standard UPC framework.

What you can do about it

For an Idaho will execution:

- Have the testator and at least two witnesses present. - Use the self-proving affidavit. - Sign at the end of the document. - Avoid using beneficiaries as witnesses.

Who this affects most

Idaho's flexible three-pathway framework reduces execution risk significantly.
