The legislature finds that adjudicating a person totally incapacitated and in need of a guardian deprives that person of all his or her civil and legal rights and that this deprivation may be unnecessary. The legislature further finds that it is desirable to make available, the least restrictive form of guardianship to assist persons who are only partially incapable of caring for their needs. Recognizing that every individual has unique needs and differing abilities, the legislature declares that it is the purpose of this act to promote the public welfare by establishing a system that permits incapacitated persons to participate as fully as possible in all decisions affecting them; that assists such persons in meeting the essential requirements for their physical health and safety, in protecting their rights, in managing their financial resources, and developing or regaining their abilities to the maximum extent possible; and that accomplishes these objectives through providing, in each case, the form of assistance that least interferes with the legal capacity of a person to act in his or her own behalf. This chapter shall be liberally construed to accomplish this purpose.
