The bill aims to establish supported decision-making as a less restrictive alternative to guardianship for adults with developmental disabilities by enacting several new sections in the Revised Code. It defines key terms such as "principal," "supported decision-making," "supported decision-making plan," and "supporter," emphasizing that adults with developmental disabilities are presumed competent unless a court determines otherwise. The bill outlines the process for creating a supported decision-making plan, which must be voluntary and documented, and specifies the roles and responsibilities of supporters in assisting the principal with decision-making while ensuring the principal's autonomy.

Additionally, the bill clarifies that entering into a supported decision-making plan does not imply incapacity and allows adults to act independently of the plan. It mandates that the Department of Developmental Disabilities develop a model plan and informational materials to aid in the implementation of supported decision-making. The legislation also includes provisions for modifying or terminating the plan and protects third parties who rely on the plan in good faith from liability, provided they are unaware of any modifications or lack of authorization.
