Missouri Revised Statutes Title XL. Additional Executive Departments § 633.110. What services may be provided--consent required, when

1. Any person suspected to have an intellectual disability or developmental disability shall be eligible for initial diagnostic and counseling services through the regional centers.

2. If it is determined by a regional center through a comprehensive evaluation that a person has an intellectual disability or a developmental disability so as to require the provision of services, and if such person, such person's parent, if the person is a minor, or legal guardian, requests that he be registered as a client of a regional center, the regional center shall, within the limits of available resources, secure a comprehensive program of any necessary services for such person. Such services may include, but need not be limited to, the following:

3. In securing the comprehensive program of services, the regional centers shall involve the client, his family or his legal guardian in decisions affecting his care, habilitation, placement or referral. Nothing in this chapter shall be construed as authorizing the care, treatment, habilitation, referral or placement of any person with an intellectual disability or developmental disability to any residential facility, day program or other specialized service without the written consent of the client, his parent, if he is a minor, or his legal guardian, unless such care, treatment, habilitation, referral, or placement is authorized pursuant to an order of the court under the provisions of chapter 475.
