Michigan Compiled Laws, Chapter 330. Mental Health Code § 330.1602

Sec. 602. (1) Guardianship for individuals with developmental disability shall be utilized only as is necessary to promote and protect the well-being of the individual, including protection from neglect, exploitation, and abuse; shall take into account the individual's abilities; shall be designed to encourage the development of maximum self-reliance and independence in the individual; and shall be ordered only to the extent necessitated by the individual's actual mental and adaptive limitations.

(2) If the court determines that some form of guardianship is necessary, partial guardianship is the preferred form of guardianship for an individual with a developmental disability.
