Missouri Living Wills Laws

Health care directives, commonly referred to as "living wills," are not actually wills but legally binding documents that list the principal's medical and end-of-life preferences should they become unable to communicate. Living wills differ from durable powers of attorney in that they don't necessarily designate a caretaker. However, an individual with the power of attorney (for health care) is obligated to follow the wishes listed in the principal's living will.

Under Missouri living will laws, the legal requirements include the following:

  • Principal must be a competent person
  • The living will must be in writing
  • It must be signed by the principal (the person to whom the living will applies)
  • It must be dated
  • If not signed "wholly" in the principal's handwriting, it must be witnessed by two adults
  • Becomes active only when the principal's condition is terminal or he or she is unable to make such decisions
  • Living will has no effect when principal is pregnant

The following chart summarizes the main provisions of Missouri's living will laws. See FindLaw's Living Will Basics section to learn more.
