How do I create an advance healthcare directive in Missouri?

Federal & State Law Editorial TeamLast reviewed: 2026-05-18

1. Types Recognized

Missouri recognizes: (a) Health Care Directive / Living Will (Mo. Rev. Stat. §§ 459.010-459.055), (b) Durable Power of Attorney for Health Care (Mo. Rev. Stat. §§ 404.800-404.870), (c) Outside Hospital DNR (§ 190.600), and (d) Missouri TPOPP (Transportable Physician Orders for Patient Preferences).

2. Statutory Form

Mo. Rev. Stat. § 459.015 contains a Living Will form; § 404.822 provides the DPOA-HC form. Substantial compliance suffices, but form use is encouraged.

3. Execution Formalities

LIVING WILL: 18+ and competent, signed by declarant or at direction, in the presence of TWO adult witnesses or before a notary (§ 459.015). DURABLE POA FOR HEALTH CARE: 18+, signed and NOTARIZED (Mo. Rev. Stat. § 404.705). Witnesses for the living will should not be: heirs/beneficiaries, persons financially responsible for care, attending physician.

4. Healthcare Agent Authority

Under § 404.820, the agent may make healthcare decisions including consent to/refusal of treatment, but to authorize WITHHOLDING/WITHDRAWING ARTIFICIAL NUTRITION OR HYDRATION the document must EXPRESSLY so state (the "Cruzan rule" reflecting Cruzan v. Director, Missouri Dept. of Health, 497 U.S. 261 (1990), 760 S.W.2d 408 (Mo. 1988)).

5. Pregnancy Clauses

Mo. Rev. Stat. § 459.025: a living will is INVALID if the patient is pregnant unless treatment is futile or causes severe harm to the mother. Position remains in force post-Dobbs.

6. Reciprocity

§ 459.045 honors directives valid where executed in compliance with that state's law.

7. TPOPP

Missouri TPOPP is a physician-signed bright-green order portable across care settings, for seriously ill patients (Missouri TPOPP Coalition guidelines).

8. Revocation

Under § 459.020, the directive is revocable at any time, regardless of mental state, by: signed/dated writing, physical destruction, or oral statement to attending physician.

9. Default Surrogate

Missouri has NO statutory surrogate hierarchy. Without a DPOA-HC, decisions for incapacitated patients without clear and convincing evidence of prior wishes (Cruzan standard) may require court-appointed guardianship under Chapter 475.
