OK HB3906

Establishes the Oklahoma Supported Decision-Making Act, allowing adults with disabilities to voluntarily enter written agreements designating one or more supporters to assist with understanding information, making decisions, and communicating choices in areas such as health care, finances, education, and housing

Supporters may help principals access records (including HIPAA-protected health information and FERPA educational records), attend meetings, and advocate for the principal's wishes, but are prohibited from making decisions on behalf of the principal or exerting undue influence

Agreements must be in writing, dated, signed by all parties in the presence of two adult witnesses, and may be terminated at any time by either the principal or supporter through verbal or written notice

Existence of a supported decision-making agreement cannot be used as evidence of incapacity in legal proceedings, and the principal retains full authority to act independently of the agreement

Provides civil and criminal liability protection for third parties (such as healthcare providers and financial institutions) who accept and rely on agreements in good faith, with effective date of November 1, 2026
