Missouri Advance Directive Form: Which Documents You Actually Need

Missouri Uses a Dual-Document System

There is no single "Missouri advance directive form." The state requires two separate legal documents, each with its own execution rules, to create a complete advance directive:

Document 1: Durable Power of Attorney for Health Care (DPOA-HC) — Names your healthcare agent and grants them authority to make medical decisions when you're incapacitated. Requires notarization.

Document 2: Health Care Choices Directive — Provides your specific written instructions about life-sustaining treatment. Requires two disinterested witnesses.

Using only one of these leaves a dangerous gap. The Directive without a DPOA-HC means no one has legal authority to make decisions that fall outside your written instructions. The DPOA-HC without a Directive means your agent has no documented guidance about what you actually want.

Why Generic "Free Forms" Fail in Missouri

Most free advance directive forms available online are based on the Uniform Health-Care Decisions Act, which Missouri has never adopted. Missouri's framework is built on RSMo Chapter 404 (the Durable Power of Attorney Law) and RSMo Chapter 459 (the Death Prolonging Procedures Act) — and carries several state-specific requirements that generic templates miss:

The tube feeding problem. Missouri requires explicit written authorization before an agent can direct withdrawal of artificially supplied nutrition and hydration. This stems from Cruzan v. Director, which set the "clear and convincing evidence" standard. A form without the specific initialing blocks for tube feeding authorization leaves your agent unable to act on this decision — even with a general DPOA-HC in place.

The witness disqualification rules. Under RSMo 404.822, Missouri excludes a long list of people from witnessing: your agent, alternates, blood relatives, anyone who could inherit from you, anyone responsible for your medical costs, and anyone employed by your treating facility. A form that doesn't flag these exclusions produces documents that hospitals routinely reject.

The notary vs. witness split. The DPOA-HC needs a notary. The Directive needs witnesses. Using the wrong execution method for either document invalidates it entirely.

What a Complete Missouri Advance Directive Package Includes

Beyond the two core documents, a legally robust Missouri advance directive should address:

• Alternate agent designations — at least one backup if your primary agent is unreachable during an emergency
• HIPAA authorization — explicit language allowing your agent to access medical records (some Missouri hospitals treat this as a separate consent)
• Post-mortem authority — the DPOA-HC can include provisions for organ donation, autopsy decisions, and disposition of remains
• Psychiatric directive language — Missouri has no standalone psychiatric advance directive statute, but you can embed mental health care instructions directly in the DPOA-HC
• TPOPP/POLST coordination notes — since December 2024, Missouri's Transportable Physician Orders for Patient Preferences form carries full EMS authority across all settings

How to Execute Each Document

DPOA-HC Execution

1. Sign in front of a licensed Missouri notary public
2. The notary acknowledges your signature (no witnesses needed for this document)
3. Include the tube feeding authorization initialing blocks
4. Name your agent and at least one alternate

Health Care Choices Directive Execution

1. Sign and date the document
2. Have two disinterested adult witnesses physically present when you sign
3. Both witnesses sign immediately after you
4. Confirm neither witness is disqualified under the RSMo 404.822 exclusion list

After Execution

• Register with Missouri's Advance Health Care Directives Registry (RSMo 459.250) for 24/7 hospital access
• Or distribute copies to your agent, primary care physician, hospital medical records, and family
• Discuss your wishes with your physician — especially if a TPOPP form is appropriate for your medical situation

When to Update Your Missouri Advance Directive

Missouri advance directives don't expire, but you should review and potentially re-execute them after:

• Divorce or legal separation filing (spouse agent designation auto-revokes under RSMo)
• Death of your named agent or alternate
• A significant change in your health status or treatment preferences
• Moving to or from Missouri (other states may not recognize Missouri's specific format)

The Missouri Advance Directive & Living Will Kit packages both required documents with the state-specific execution checklists, witness eligibility verification, and the tube feeding authorization language that satisfies Missouri's Cruzan standard.
