Florida’s Involuntary Commitment law
394.459 Rights of patients
(c) Each person who remains at a receiving or treatment facility for more than 12 hours shall be given a physical examination by a health practitioner authorized by law to give such examinations, within 24 hours after arrival at such facility.
(3) RIGHT TO EXPRESS AND INFORMED PATIENT CONSENT.--
(a)1. Each patient entering treatment shall be asked to give express and informed consent for admission or treatment. If the patient has been adjudicated incapacitated or found to be incompetent to consent to treatment, express and informed consent to treatment shall be sought instead from the patient's guardian or guardian advocate. If the patient is a minor, express and informed consent for admission or treatment shall also be requested from the patient's guardian. Express and informed consent for admission or treatment of a patient under 18 years of age shall be required from the patient's guardian, unless the minor is seeking outpatient crisis intervention services under s. 394.4784. Express and informed consent for admission or treatment given by a patient who is under 18 years of age shall not be a condition of admission when the patient's guardian gives express and informed consent for the patient's admission pursuant to s. 394.463 or s. 394.467.
394.4597 Persons to be notified; patient's representative
(2) INVOLUNTARY PATIENTS.—
a) At the time a patient is admitted to a facility for involuntary examination or placement, or when a petition for involuntary placement is filed, the names, addresses, and telephone numbers of the patient's guardian or guardian advocate, or representative if the patient has no guardian, and the patient's attorney shall be entered in the patient's clinical record.
(b) If the patient has no guardian, the patient shall be asked to designate a representative. If the patient is unable or unwilling to designate a representative, the facility shall select a representative.
(c) The patient shall be consulted with regard to the selection of a representative by the receiving or treatment facility and shall have authority to request that any such representative be replaced.
394.463 Involuntary examination.--
(1) CRITERIA.--A person may be taken to a receiving facility for involuntary examination if there is reason to believe that the person has a mental illness and because of his or her mental illness:
(a)1. The person has refused voluntary examination after conscientious explanation and disclosure of the purpose of the examination; or
2. The person is unable to determine for himself or herself whether examination is necessary; and
(b)1. Without care or treatment, the person is likely to suffer from neglect or refuse to care for himself or herself; such neglect or refusal poses a real and present threat of substantial harm to his or her well-being; and it is not apparent that such harm may be avoided through the help of willing family members or friends or the provision of other services; or
2. There is a substantial likelihood that without care or treatment the person will cause serious bodily harm to himself or herself or others in the near future, as evidenced by recent behavior.
f) A patient shall be examined by a physician or clinical psychologist at a receiving facility without unnecessary delay and may, upon the order of a physician, be given emergency treatment if it is determined that such treatment is necessary for the safety of the patient or others. The patient may not be released by the receiving facility or its contractor without the documented approval of a psychiatrist, a clinical psychologist, or, if the receiving facility is a hospital, the release may also be approved by an attending emergency department physician with experience in the diagnosis and treatment of mental and nervous disorders and after completion of an involuntary examination pursuant to this subsection. However, a patient may not be held in a receiving facility for involuntary examination longer than 72 hours.
(g) A person for whom an involuntary examination has been initiated who is being evaluated or treated at a hospital for an emergency medical condition specified in s. 395.002 must be examined by a receiving facility within 72 hours. The 72-hour period begins when the patient arrives at the hospital and ceases when the attending physician documents that the patient has an emergency medical condition.
394.4655 Involuntary outpatient placement.--
(1) CRITERIA FOR INVOLUNTARY OUTPATIENT PLACEMENT.--A person may be ordered to involuntary outpatient placement upon a finding of the court that by clear and convincing evidence:
(a) The person is 18 years of age or older;
(b) The person has a mental illness;
(c) The person is unlikely to survive safely in the community without supervision, based on a clinical determination;
(d) The person has a history of lack of compliance with treatment for mental illness;
(e) The person has:
1. At least twice within the immediately preceding 36 months been involuntarily admitted to a receiving or treatment facility as defined in s. 394.455, or has received mental health services in a forensic or correctional facility. The 36-month period does not include any period during which the person was admitted or incarcerated; or
2. Engaged in one or more acts of serious violent behavior toward self or others, or attempts at serious bodily harm to himself or herself or others, within the preceding 36 months;
(f) The person is, as a result of his or her mental illness, unlikely to voluntarily participate in the recommended treatment plan and either he or she has refused voluntary placement for treatment after sufficient and conscientious explanation and disclosure of the purpose of placement for treatment or he or she is unable to determine for himself or herself whether placement is necessary;
(g) In view of the person's treatment history and current behavior, the person is in need of involuntary outpatient placement in order to prevent a relapse or deterioration that would be likely to result in serious bodily harm to himself or herself or others, or a substantial harm to his or her well-being as set forth in s. 394.463(1);
(h) It is likely that the person will benefit from involuntary outpatient placement; and
(i) All available, less restrictive alternatives that would offer an opportunity for improvement of his or her condition have been judged to be inappropriate or unavailable.
6) HEARING ON INVOLUNTARY OUTPATIENT PLACEMENT.--
(a)1. The court shall hold the hearing on involuntary outpatient placement within 5 working days after the filing of the petition, unless a continuance is granted. The hearing shall be held in the county where the petition is filed, shall be as convenient to the patient as is consistent with orderly procedure, and shall be conducted in physical settings not likely to be injurious to the patient's condition. If the court finds that the patient's attendance at the hearing is not consistent with the best interests of the patient and if the patient's counsel does not object, the court may waive the presence of the patient from all or any portion of the hearing. The state attorney for the circuit in which the patient is located shall represent the state, rather than the petitioner, as the real party in interest in the proceeding.
7) PROCEDURE FOR CONTINUED INVOLUNTARY OUTPATIENT PLACEMENT.--
(a)1. If the person continues to meet the criteria for involuntary outpatient placement, the service provider shall, before the expiration of the period during which the treatment is ordered for the person, file in the circuit court a petition for continued involuntary outpatient placement.
