Any person with capacity may create a mental health advance directive expressing his or her preferences and instructions about mental health treatment in the event of incapacity.  The directive must be respected by medical and mental health professionals, guardians, agents, attorneys-in-fact, and other surrogate decision makers acting on behalf of the document's creator.


A directive may include one or more of the following provisions:

  • preferences and instructions for mental health treatment;
  • consent, or refusal to consent to specific types of treatment or admission and retention for inpatient treatment;
  • descriptions of situations that may cause a mental health crisis;
  • suggestions for alternative responses that supplement or are in lieu of direct mental health treatment; and
  • appointment of an agent to make a mental health treatment decision.


A directive must be in writing, dated, signed, and witnessed by two people and must substantially follow the statutory form.  There are limitations on who may witness a directive or serve as an agent that are focused on excluding persons with real or potential conflicts of interest.




A person with capacity is a person who can give informed consent to medical treatment.  A person is presumed to have capacity to create or revoke a directive.  Generally, persons under the age of 18 cannot provide consent for their own medical procedures.  There are several exceptions, one of which is if a minor is aged 13 or older and seeking behavioral health treatment.


A person, the person's agent, a mental health professional, or a health care provider may seek a determination of a person's capacity.  Incapacity is determined by either:  (1) a court; (2) one mental health professional and one health care provider; or (3) two health care providers.  At least one mental health professional or health care provider must personally examine the person before making a capacity determination.

Summary of Engrossed Substitute Bill:

A mental health advance directive may be acknowledged before a notary public or other individual authorized by law to take acknowledgements instead of two witnesses.


Changes are made to the statutory form used to create a mental health advance directive including, but not limited to: streamlining and simplifying certain language used in the body of the form; adding a section for the principal to describe what works for the principal and the principal's diagnoses, medications, and best approach to treatment; and granting power to the agent to act as the person's personal representative for the purpose of the Health Insurance Portability and Accountability Act.


A substance use disorder professional may make a capacity determination instead of a mental health professional.


A person who is at least 13 years of age but under the age of 18 is considered to have capacity for the purpose of executing a mental health advance directive if the person is able to demonstrate that they are capable of making informed decisions related to behavioral health care.  A mental health advance directive does not restrict the right of a parent to seek parent-initiated treatment pursuant to involuntary treatment laws for minors.


As it relates to mental health advance directives, references to mental health are changed to behavioral health.  Less restrictive alternative treatment must include consultation about the formation of a mental health advance directive
