There are a few alternatives. First, the community mental health center, hospital, or other emergency receiving or evaluating facility can petition the court to determine whether outpatient treatment should be ordered if a doctor or other qualified licensed or registered professional certifies the need for (and availability of) involuntary outpatient treatment. See the Outpatient Treatment Proceedings.
Secondly, if the person has been certified to need involuntary outpatient treatment by a private physician or other qualified professional not connected with a facility as defined by the code (and the treatment the person needs is available), any interested person may petition the appropriate court for an order that the person receive a full evaluation.
Finally, if the person has not been seen by a qualified professional who is authorized to sign the certifications described herein, the person may apply to the community mental health center where outpatient treatment is provided to conduct a preliminary investigation to determine whether there is probable cause to believe the person is a mentally ill, drug dependent, or alcoholic person in need of involuntary treatment. If such a probable cause finding is made, the center must then petition the court for an order for the person to be evaluated. See the Court-Ordered Evaluation Proceedings.
