Idaho legalized electronic wills in 2023 — and asks for something most e-will states don’t: the electronic record has to be tamper-evident. Idaho also lets any emancipated minor make a will at any age, and accepts handwritten wills with no date required. The part that matters most, though, is that Idaho is a community property state: your half of the community property passes to your spouse automatically, but your separate property splits in half the moment you have any children at all. Online services prepare an Idaho-specific will for $199–$299. Every rule below cites the Idaho Code.
Most Idaho adults can finish a legally valid will in under an hour.
Two witnesses, a signature, and clear wishes — that’s the whole requirement. An online service like Trust & Will prepares an Idaho-specific will with the witness pages ready to sign.

Idaho Will Requirements (2026)
| Requirement | Idaho rule | Statute |
|---|---|---|
| In writing | A written record — or a tamper-evident electronic record under the 2023 electronic wills act | §§ 15-2-502, 15-2-1105 |
| Signed | By you, or in your name by another person in your presence and at your direction | § 15-2-502 |
| Witnessed | At least two persons, each of whom witnessed either the signing or your acknowledgment — they need not be present together | § 15-2-502 |
| Notarized | Not required for validity — the notary appears only in the optional self-proving affidavit | § 15-2-504 |
Who can make a will: “Any emancipated minor or any person eighteen (18) or more years of age who is of sound mind” (§ 15-2-501). The emancipated-minor clause has no age floor at all — most states either stop at a flat 18 or, like Oregon, add a married-or-emancipated alternative. The same section adds that a married woman may dispose of her property, separate or community, in the same manner as any other person.
If you physically cannot sign, Idaho Code § 51-109 provides the route: you may direct an individual other than the notary to sign your name, and the notary inserts “Signature affixed by (name of other individual) at the direction of (name of individual)” or words of similar import.
Handwritten Wills Are Valid in Idaho — No Date Required
Section 15-2-503 is one sentence: a will that does not comply with § 15-2-502 “is valid as a holographic will, whether or not witnessed, if the signature and the material provisions are in the handwriting of the testator.”
Two elements only: signature and material provisions. No date, no witnesses, no notary. That puts Idaho with Utah and Colorado among the most permissive holographic states, and apart from Nevada next door, where the date is a statutory element and an undated handwritten will fails outright.
“Material provisions” means the operative terms — who gets what. A preprinted form with those terms filled in by hand can qualify, because the printed words are not what is being tested.
Valid is not the same as advisable. A holographic will arrives with no witnesses to confirm your capacity, and it is the format most often contested in probate court. Idaho simply gives it plenty of room to survive.
Electronic Wills: Legal in Idaho Since 2023
Idaho adopted the Uniform Electronic Wills Act in 2023 (ch. 104), codified at Idaho Code §§ 15-2-1101 to 15-2-1108. Under § 15-2-1105(1), an electronic will must be:
- a tamper-evident electronic record that is readable as text at the time of signing;
- signed by you, or in your name by another individual in your physical presence and at your direction; and
- signed in your physical or electronic presence by at least two individuals, each of whom is a resident of a state at the time of signing, within a reasonable time after witnessing.
The tamper-evidence requirement is the Idaho distinctive. Utah, Oklahoma and Kentucky ask only for a record “readable as text.” Idaho requires the record itself to reveal whether it has been altered since signing. A plain PDF saved to cloud storage does not meet that standard — you need a platform that produces a genuinely tamper-evident file, which in practice means an electronic-will service rather than a word processor.
“Electronic presence” is defined tightly: § 15-2-1102(3) means individuals in different locations communicating in real time by means of communication technology, and § 15-2-1102(1) defines that technology as a device or process allowing two or more individuals to communicate simultaneously by sight and sound. Live video, both ways. Not a phone call, and not email.
Idaho’s witness rule is broad: each witness need only be “a resident of a state” — any state. That matches Oklahoma and is far looser than Kentucky’s requirement that both witnesses be Kentucky residents standing in Kentucky.
An electronic will can be made self-proving at execution under § 15-2-1108, using the ordinary affidavit form from § 15-2-504(1) with “presence and hearing” replaced by “physical or electronic presence.” Note the detail in § 15-2-1108(4): the acknowledgment or affidavit must itself be a tamper-evident electronic record, affixed to or logically associated with the will.
Dying Without a Will in Idaho: Community Property Saves the Day, Separate Property Doesn’t
Idaho is a community property state, and § 15-2-102 splits the answer explicitly.
Community property
Section 15-2-102(b)(1): “The one-half (1/2) of community property which belongs to the decedent passes to the surviving spouse.” Your spouse already owns their own half. Your half goes to them too. Community property — broadly, what the two of you earned during the marriage — reaches your spouse in full without a will.
Separate property
Separate property is what you owned before the marriage, plus anything you inherited or received as a gift during it. It runs through a different table:
| Your situation | What your spouse receives of your SEPARATE property |
|---|---|
| No surviving issue and no parent | The entire intestate estate (§ 15-2-102(a)(1)) |
| No surviving issue, but a parent survives | One-half — your parents take the rest (§ 15-2-102(a)(2)) |
| Any surviving issue | One-half — your children take the rest (§ 15-2-102(a)(3)) |
Note what the third row does not ask. Section 15-2-102(a)(3) says “if there are surviving issue of the deceased spouse” — full stop. It does not matter whether those children are also your spouse’s. A couple married thirty years with three children together still leaves the surviving spouse only half of the deceased spouse’s separate property, with the children taking the other half.
The childless case surprises people too: if you and your spouse have no children and one of your parents is living, your spouse splits your separate property with your parents. A house you owned before the marriage is separate property, and your spouse can end up co-owning it with your mother.
Idaho Has No Death Tax
Idaho has no estate tax, no inheritance tax and no gift tax. Idaho’s estate tax applied only to deaths before 2005; the Idaho State Tax Commission confirms there is nothing to file. Only the federal estate tax can reach an Idaho estate, and it applies to very few. Compare the states in our state-by-state comparison.

What an Idaho Will Does Not Do
1. A will does not avoid probate. Idaho probate is a court process on the public record, though Idaho’s informal probate is comparatively efficient and small-estate affidavit procedures exist. See what a living trust costs in Idaho, how small estate affidavits work, and our guide to avoiding probate.
2. A will does not control your spouse’s half of the community property. You can leave only your own half. Half of everything the two of you built during the marriage is already theirs, and no will reaches it.
3. A will does not cover incapacity, and does not override beneficiary designations. Pair it with a durable power of attorney and a living will or health care directive — see the five documents every family needs — and keep your beneficiary forms current.
Will vs. Trust for Idaho Families
Every Idaho adult needs a will — no default rule names a guardian for your children, and the separate-property table hands half of what you owned before the marriage to your children rather than your spouse. There is no state death tax pushing Idahoans toward a trust, so the trust question here is about probate avoidance, privacy, keeping minors’ shares out of a conservatorship, and characterizing community versus separate property clearly while you can still explain it.

FAQ
Does a will have to be notarized in Idaho?
No. Validity takes your signature and two witnesses, each of whom witnessed the signing or your acknowledgment (§ 15-2-502). The notary appears only in the optional self-proving affidavit (§ 15-2-504).
Are handwritten wills legal in Idaho?
Yes, with no witnesses, if the signature and the material provisions are in your handwriting (§ 15-2-503). Idaho requires no date — unlike Nevada next door, where an undated handwritten will fails.
Can I make an electronic will in Idaho?
Yes — since 2023, under Idaho Code §§ 15-2-1101 to 15-2-1108. The record must be tamper-evident and readable as text at signing, and two witnesses, each a resident of a state, must sign in your physical or electronic presence (§ 15-2-1105). The tamper-evidence requirement is stricter than Utah’s or Oklahoma’s.
Can an emancipated minor make a will in Idaho?
Yes. Section 15-2-501 permits “any emancipated minor or any person eighteen (18) or more years of age who is of sound mind” to make a will. The emancipated-minor route has no age floor written into the section.
What happens if I die without a will in Idaho?
Your half of the community property passes to your spouse (§ 15-2-102(b)). Your separate property is split: your spouse takes it all only if you leave no issue and no parent; otherwise they take one-half, whether the other half goes to your parents or to your children — including children you had together (§ 15-2-102(a)).
Does Idaho have an estate or inheritance tax?
No. Idaho has no estate tax, no inheritance tax and no gift tax; its estate tax applied only to deaths before 2005.
