A petition for involuntary assessment and stabilization must contain the name of the respondent; the name of the applicant or applicants; the relationship between the respondent and the applicant; the name of the respondent’s attorney, if known, and a statement of the respondent’s ability to afford an attorney; and must state facts to support the need for involuntary assessment and stabilization, including:
(1) The reason for the petitioner’s belief that the respondent is substance abuse impaired; and
(2) The reason for the petitioner’s belief that because of such impairment the respondent has lost the power of self-control with respect to substance abuse; and either
(3)(a) The reason the petitioner believes that the respondent has inflicted or is likely to inflict physical harm on himself or herself or others unless admitted; or
(b) The reason the petitioner believes that the respondent’s refusal to voluntarily receive care is based on judgment so impaired by reason of substance abuse that the respondent is incapable of appreciating his or her need for care and of making a rational decision regarding that need for care. If the respondent has refused to submit to an assessment, such refusal must be alleged in the petition.
