Will

Idaho Code §15-2-501 et seq.

Witnesses: 2 required

Two witnesses, each having witnessed either the testator's signing of the will or the testator's acknowledgment of the signature or of the will, must sign the will (Idaho Code §15-2-502)

Notarization: Recommended

Not legally required, but recommended for self-proving affidavit

Holographic will: Valid

Handwritten wills without witnesses are recognized in Idaho

Self-proving affidavit: Available

Allows the will to be admitted to probate without witness testimony

ViewWitness disqualification / interested-witness rule
Idaho Code §15-2-505: any person eighteen or more years of age and generally competent to be a witness may act as a witness to a will, and a will or any provision of it is not invalid because the will is signed by an interested witness. Idaho follows the UPC rule and has no purge statute, so a gift to an attesting witness remains effective, but Idaho adds one requirement most UPC states omit: a witness must be at least 18 years old. Using witnesses who take nothing under the will is still the safer practice.

Living Trust

Idaho Code §32-906 et seq.

Witnesses: None required

No formal execution requirements beyond settlor signature; notarization strongly recommended when funding real property

Notarization: Recommended

Not legally required for the trust document, but needed to transfer real property

ViewCommunity property article
Adds an Article VII: Community Property Provisions covering classification of community vs. separate property, the surviving spouse's one-half interest, federal IRC §1014(b)(6) double-stepped-up basis, and record-keeping for traced contributions.

Durable Power of Attorney

Witnesses: None required

No witnesses required for power of attorney

Notarization: Recommended

Notarization is not legally required but is recommended. It creates a presumption of genuine signature and simplifies third-party acceptance.

State-specific notes

Acknowledgment before a notary public is not required for validity but creates a rebuttable presumption that the signature is genuine. Idaho Code §15-12-105
Durability is presumed unless the instrument states otherwise. Idaho Code §15-12-104
An instrument executed by an agent cannot be recorded until the power of attorney authorizing it is filed for record in the same office (Idaho Code §55-806). Recording in Idaho also requires that the execution be acknowledged or proved, and it happens in the county where the real property is situated, so a POA the agent will use to convey real property should be acknowledged before a notary at signing (Idaho Code §§55-805, 55-808)
Idaho publishes a statutory form power of attorney, and the IMPORTANT INFORMATION notice printed at the top of your document is that form's notice reproduced verbatim (Idaho Code §15-12-301)
ViewWarning notice for the principal
IMPORTANT INFORMATION This power of attorney authorizes another person (your agent) to make decisions concerning your property for you (the principal). Your agent can make decisions and act with respect to your property (including your money) whether or not you are able to act for yourself. The meaning of authority over subjects listed on this form is explained in the uniform power of attorney act, chapter 12, title 15, Idaho Code. This power of attorney does not authorize the agent to make health care decisions for you. You should select someone you trust to serve as your agent. The agent's authority will continue until your death unless you revoke the power of attorney or the agent resigns. Your agent is entitled to reasonable compensation unless you state otherwise in the Special Instructions. This form provides for designation of one (1) agent. If you wish to name more than one (1) agent, you may name a coagent in the Special Instructions. Coagents are not required to act together unless you include that requirement in the Special Instructions. If your agent is unable or unwilling to act for you, your power of attorney will end unless you have named a successor agent. You may also name a second successor agent. This power of attorney becomes effective immediately unless you state otherwise in the Special Instructions. If you have questions about the power of attorney or the authority you are granting to your agent, you should seek legal advice before signing this form.

Advance Care Planning Document (ACPD)

Idaho Code §39-4501 et seq.; contents and validity at §39-4510; execution and duration at §39-4512; defined term at §39-4502(1)

Witnesses: None required

No witnesses required

Notarization: Not required

Notarization is not required but may be accepted

State-specific notes

Idaho does not require witnesses or notarization for a valid advance care planning document (Idaho Code §39-4510 contents and validity, §39-4512 execution and duration; defined at §39-4502(1))
Execution on a statutory form is strongly recommended for acceptance by healthcare providers
ViewWitness disqualification recital
Idaho Code §39-4510 sets the mandatory contents of an advance care planning document and does not require the document to be witnessed: §39-4510(2)(j) lists the names and contact information of witnesses among the optional elements, and §39-4510(2)(k) lists notarization as optional. Idaho therefore imposes no statutory list of disqualified witnesses for this document. Where witnesses are used as a precaution, sound practice is a competent adult who is not the health care agent or any successor agent named in the document and who has no direct financial interest in the principal's estate or in the cost of the principal's care.

Community property

Idaho is a community property state. Assets acquired during marriage are jointly owned by both spouses. This affects every document in your estate plan.

Married couples should consider how community property rules interact with their will, trust, power of attorney, and healthcare directive to ensure consistent coverage.

Electronic will status

Idaho has adopted electronic will legislation (2023). You may be able to create, sign, and witness a will electronically using approved methods.

Digital assets access

Idaho has adopted RUFADAA (2016). This is the Revised Uniform Fiduciary Access to Digital Assets Act, which lets your executor, trustee, or agent access your email, social media, cryptocurrency wallets, cloud storage, and other digital accounts after death or incapacity.

To take advantage of RUFADAA, your will, trust, or power of attorney must explicitly grant authority to access digital assets. Without explicit authorization, service providers can deny access even to a court-appointed executor.

Remote online notarization (RON)

Idaho authorized RON in 2019. The law took effect on January 1, 2020. Idaho's general RON authority (Idaho Code §51-114A (2019)) became operative Jan. 1, 2020. The dedicated remote-witnessing route in Idaho Code §15-2-1101 et seq. (2023) applies only to an electronic will that is a tamper-evident electronic record under Idaho Code §15-2-1105; it is not available for a will signed on paper, which must be witnessed under Idaho Code §15-2-502 by two people physically present at the signing or at the testator's acknowledgment.

Remote online witnessing (ROW)

Idaho does not allow remote online witnessing for estate planning documents. Witnesses must be physically present when you sign. Not available for an Idaho will signed on paper. Idaho Code §15-2-502 requires two witnesses and carries no electronic-presence provision; its only cross-reference, Idaho Code §51-109, concerns signature by another individual at the direction of a testator physically unable to sign, not remote witnessing. Idaho's electronic-presence authority sits in the Uniform Electronic Wills Act (Idaho Code §15-2-1101 et seq., 2023), and Idaho Code §15-2-1105 confines it to an electronic will that is a tamper-evident electronic record.
