1. At the expiration of the ninety-six hour period, the respondent may be detained and treated involuntarily for an additional two judicial days only if the head of the mental health facility or a mental health coordinator either has filed a petition for additional inpatient detention and treatment not to exceed twenty-one days or has filed a petition for outpatient detention and treatment for a period not to exceed one hundred eighty days.

2. Within ninety-six hours following initial detention, the head of the facility or the mental health coordinator may file or cause to be filed either a petition for a twenty-one-day inpatient involuntary detention and treatment period or a petition for outpatient detention and treatment for a period not to exceed one hundred eighty days, provided he has reasonable cause to believe that the person is mentally ill and as a result presents a likelihood of serious harm to himself or others. The court shall serve the petition and list of prospective witnesses for the petitioner upon the respondent and his attorney at least twenty-four hours before the hearing. The head of the facility shall also notify the mental health coordinator if the petition is not filed by the mental health coordinator. The petition shall:

(1) Allege that the respondent, by reason of mental illness, presents a likelihood of serious harm to himself or to others;

(2) Allege that the respondent is in need of continued detention and treatment either on an inpatient basis or on an outpatient basis;

(3) Allege the specific behavior of the respondent or the facts which support such conclusion;

(4) Affirm that attempts were made to provide necessary care, treatment and services in the least restrictive environment to the respondent on a voluntary basis, but either the petitioner believes that the respondent lacks the capacity to voluntarily consent to care, treatment and services or the respondent refuses to voluntarily consent to care, treatment and services such that proceeding with a petition for the respondent’s civil detention in the least restrictive environment is necessary;

(5) Allege that there will be appropriate support from family, friends, case managers or others during the period of outpatient detention and treatment in the community if such commitment is sought;

(6) Specify the mental health program that is appropriate to handle the respondent’s condition and that has agreed to accept the respondent;

(7) Specify the range of care, treatment and services that shall be provided to the respondent if the petition for further detention is sustained by the court;

(8) Name the entities that have agreed to fund and provide the specified interventions; and

(9) Be verified by a psychiatrist or by a licensed physician and a mental health professional who have examined the respondent.

3. The petitioner shall consider whether based on the respondent’s condition and treatment history, the respondent meets the criteria in chapter 475, so that appointment of a full or limited guardian or conservator is appropriate for the court to consider, and if deemed so, the petitioner then shall proceed as specified in subsection 4 of this section.

4. If the head of the mental health facility, or his designee, or the mental health coordinator believes that the respondent, because of a mental illness or mental disorder, may be incapacitated or disabled as defined in chapter 475, the head of the mental health facility or mental health coordinator shall cause a petition to be filed pursuant to section 475.060 and section 475.061, if applicable, with the court having probate jurisdiction as determined by section 475.035. In addition, if the head of the mental health facility, his designee or the mental health coordinator believes it appropriate, he shall proceed with obtaining an order for the respondent’s temporary emergency detention as provided for in section 475.355. Furthermore, the hearing on the petition filed pursuant to chapter 475 shall be conducted pursuant to the requirements of section 475.075 and other appropriate sections of chapter 475, and shall be held within two judicial days after termination of the ninety-six-hour civil detention period unless continued for good cause shown. Nothing contained in this subsection shall restrict or prohibit the head of the mental health facility, his designee or the mental health coordinator from proceeding under the appropriate provisions of this chapter if the petition for guardianship or conservatorship is denied.
