The Oklahoma Supported Decision-Making Act aims to provide a framework for adults with disabilities to receive assistance in making informed decisions while retaining their autonomy. The Act defines key terms such as "adult," "supporter," and "supported decision-making agreement," and outlines the purpose of the legislation, which includes enabling adults to gather information, make decisions, and communicate those decisions with the help of designated supporters. The Act emphasizes that supporters cannot make decisions on behalf of the adult or exert undue influence, ensuring that the adult's rights and preferences are respected.

The legislation also establishes the process for entering into and terminating supported decision-making agreements, which must be in writing and signed by all parties in the presence of witnesses. It clarifies that such agreements cannot be used as evidence of incapacity in legal proceedings and allows for the enforcement of decisions made with the support of a designated supporter. Additionally, the Act provides protections for individuals who rely on these agreements in good faith, relieving them of civil or criminal liability. The Act will take effect on November 1, 2026.
