MO HB2059

Creates a new family intervention order (FIO) process under sections 455.100 to 455.155 for family members to petition courts to compel substance abuse treatment for relatives with chemical substance abuse issues.

Requires courts to order respondents to undergo prevention/intervention evaluations and, if determined to be substance abusers, to participate in treatment programs (inpatient, outpatient, medication-assisted, or recovery support organizations).

Mandates that abuse and neglect reporters be asked about potential chemical substance abuse and informed about how to obtain a family intervention order if they are family members of alleged abusers.

Allows courts in dissolution of marriage cases to consider family intervention orders when chemical substance abuse is a factor and permits awarding custody to the party without substance abuse issues if that party otherwise meets legal requirements.

Establishes that failure to comply with a family intervention order results in issuance of a full order of protection and may result in the non-compliant family member being deemed the least preferable parent for custody determinations.
