Idaho Code § 66-602: Declarations for mental health treatment.

(1) A competent adult may make a declaration of preferences or instructions regarding mental health treatment. The preferences or instructions may include consent to or refusal of mental health treatment. The declaration shall name an attorney-in-fact (agent) and an alternative agent whose authority continues in effect as long as the declaration appointing the agent is in effect or until the agent has withdrawn. If a declaration for mental health treatment has been invoked and is in effect, the declaration remains effective until the principal is no longer incapable.

(2) A declaration for mental health treatment continues in effect until revoked. A declaration may be revoked in whole or in part at any time by the principal if the principal is not incapable. A revocation is effective when a capable principal communicates the revocation to the attending physician or other provider. The attending physician or other provider shall note the revocation as part of the principal’s medical record.
