Idaho Mental Health Advance Directive: Declaration for Mental Health Treatment

If you or a loved one lives with a serious mental health condition — bipolar disorder, schizophrenia, severe depression, PTSD — there is a legal tool in Idaho that most people have never heard of. The Declaration for Mental Health Treatment under Idaho Code § 66-613 lets you document your psychiatric treatment preferences while you are stable, so they are honored during a crisis when you may lack the capacity to speak for yourself.

This is a completely separate document from the standard advance directive, with different rules, different requirements, and different consequences if you get the execution wrong.

What the Declaration Covers

The Declaration for Mental Health Treatment allows you to specify:

• Medications: Which psychiatric medications you consent to, which you refuse, and any drugs you have had adverse reactions to in the past
• Electroconvulsive therapy (ECT): Whether you consent, refuse, or consent only under specific conditions
• Voluntary admission: Your preferences for inpatient psychiatric admission, including a maximum duration (the declaration can limit voluntary admission to 17 days)
• Healthcare agent: A designated person to make psychiatric treatment decisions on your behalf during a crisis
• Facility preferences: Which treatment facilities or hospitals you prefer or want to avoid

How It Differs From a Standard Advance Directive

The standard Idaho Living Will and Durable Power of Attorney for Health Care (Idaho Code § 39-4510) covers general medical decisions — ventilators, feeding tubes, CPR, end-of-life care. It does not address psychiatric-specific treatment decisions, and it does not include provisions for involuntary mental health situations.

Key differences:

If you have both documents, they work together — the general directive handles medical emergencies, and the mental health declaration handles psychiatric crises. Neither replaces the other.

The Two-Witness Requirement

This is where families and individuals most commonly make a fatal error. Because the standard Idaho advance directive requires no witnesses, people assume the same rule applies to the psychiatric declaration. It does not.

The Declaration for Mental Health Treatment is legally void unless signed by two competent adult witnesses. Both witnesses must be:

• At least 18 years old
• Mentally competent
• Not a relative of the declarant
• Not a healthcare provider or employee of a healthcare provider
• Not the designated agent named in the document

If either witness fails to meet these requirements, or if there is only one witness, the entire document is unenforceable. A mental health facility can refuse to recognize your agent's authority and ignore your treatment preferences entirely.

Good witness choices: a neighbor, a coworker, a friend, a librarian, a member of your faith community. Bad choices: your parent, your therapist, your psychiatrist's receptionist, or the agent you just named.

When the Declaration Activates

The declaration takes effect when a qualified mental health professional — not just any physician — determines that you are unable to make your own psychiatric treatment decisions. This is a higher and more specific threshold than the general advance directive, which activates when an attending physician determines you cannot communicate rationally.

Once activated, your designated agent can:

• Consent to or refuse psychiatric medications on your behalf
• Authorize or decline ECT
• Consent to voluntary psychiatric admission (within the limits you specified)
• Advocate for your treatment preferences with the clinical team

Your agent cannot commit you involuntarily — that requires a separate legal process with court oversight.

How to Create the Declaration

1. Obtain the form from the Idaho Court Assistance Office or through the National Resource Center on Psychiatric Advance Directives (nrc-pad.org/states/idaho-faq/)
2. Complete your treatment preferences — be as specific as possible about medications, procedures, and facilities
3. Name your agent (and an alternate)
4. Sign in the presence of two qualifying witnesses who also sign the document
5. Distribute copies to your agent, your psychiatrist or therapist, your primary care physician, and any treatment facility where you receive regular care
6. Consider registering the document with the Idaho Healthcare Directive Registry alongside your general advance directive

Reviewing and Revoking the Declaration

You can revoke the declaration at any time while you have capacity. You can also update it to reflect new medication experiences, changed facility preferences, or a different designated agent.

Mental health treatment evolves — a medication that worked three years ago may have been replaced, or you may have had a negative experience with a drug that was previously acceptable. Review the declaration annually or after any significant change in your treatment plan.

Why This Document Matters for Dementia Patients Too

The psychiatric declaration is not only for people with traditional mental health diagnoses. Patients with dementia often experience psychiatric symptoms — agitation, psychosis, severe anxiety, depression — as the disease progresses. A Declaration for Mental Health Treatment can specify preferences for psychotropic medications and involuntary admission limits that the standard advance directive does not address.

The Idaho Advance Directive & Living Will Kit covers both the standard advance directive and the psychiatric declaration, including the specific execution requirements that differ between the two documents and the signing checklists that prevent the most common errors.
