The bill amends Section 40.1-1-10 of the General Laws to establish a deinstitutionalization subsidy aid program within the Department of Behavioral Healthcare, Developmental Disabilities, and Hospitals. The program aims to provide financial assistance to qualified applicants, which now includes not only biological parents but also adoptive parents and siblings of individuals who have been residents or patients of specific state institutions. The language in the bill replaces the term "parent" with "qualified parent applicant" and expands the definition of "appropriate relative" to include adoptive parents and siblings, thereby broadening the scope of who can apply for and receive subsidy aid.

Additionally, the bill mandates the Department to develop options and recommendations for expanding shared living services for siblings of individuals with developmental disabilities who can no longer be cared for at home by aging parents. The department is required to submit these recommendations to the governor and the General Assembly by December 31, 2013. The act will take effect upon passage, reflecting a commitment to enhancing support for families caring for individuals with developmental disabilities.
