An Idaho living will is a written document that states your wishes for medical treatment if illness or injury leaves you unable to communicate. Idaho law calls this document an Advance Care Planning Document (ACPD), and it is governed by the state’s Medical Consent and Natural Death Act.

In the Idaho living will form, you can also name a health care agent. This person, sometimes called a health care proxy, can make medical decisions for you if you are unable to make them yourself.
An Idaho living will, called an Advance Care Planning Document (ACPD) under state law, is valid when it meets the requirements in Idaho Code § 39-4510. Any competent person aged eighteen (18) years or older may sign one, either personally or through an authorized agent, and the document must be in writing.[1.1] Idaho law does not require witnesses or notarization for the document to be valid.[1.3]
These requirements come from the Medical Consent and Natural Death Act, Idaho Code Title 39, Chapter 45.
A living will is also called an advance directive or a health care directive. Idaho’s own statute calls it an Advance Care Planning Document, or ACPD.
Idaho law does not require witnesses or notarization, but the FormsPal document itself still asks you to sign it in front of two witnesses. Follow the form’s own signature instructions even though state law does not make witnessing mandatory. Leaving the witness lines blank on this particular document could leave a health care provider unsure whether the copy they were given is complete.
An ACPD may but is not required to include the following: the electronic mail address of the person executing the ACPD; nomination of one (1) or more persons to act as a health care agent; the name, mailing address, electronic mail address, and telephone number of any person nominated as a health care agent, as well as such person’s relationship to the person executing the ACPD; resuscitation instructions; instructions regarding pregnancy; instructions for the release of information protected by the federal health insurance portability and accountability act; instructions for end-of-life care; a description of treatment objectives; the names and contact information of witnesses to the execution of the ACPD; and notarization.
In plain terms, these are optional additions you may include if you want to. None of them is required to make the document valid. You can leave any of them blank and the document still works, as long as it is written, dated, and signed.
If you change your mind, you can revoke your Idaho living will. The FormsPal document states that you may revoke or terminate it at any time. In practice, people usually do this by destroying all copies of the document and clearly telling their health care agent and providers that it no longer applies.
If you later sign a new living will, tell your agent and providers about the new document too, so everyone is working from the same instructions.
Under Idaho Code § 39-4511A, you may revoke your ACPD at any time by destroying it or having it destroyed in your presence and at your direction, by a signed written revocation, by an oral statement of intent, or by any other act that clearly shows you intend to revoke it. Tell your health care providers when you do.[2.1]
