Oklahoma Presumption of Competence is a legal doctrine that is recognized by the state of Oklahoma. It presumes that individuals with developmental disabilities possess the same capacity to understand and make decisions as those without disabilities. This presumption is made to ensure that individuals with disabilities are not denied their right to make decisions concerning their own lives. The presumption applies to all aspects of decision-making, including decisions regarding care, treatment, and services. There are three types of Oklahoma Presumption of Competence: General Presumption of Competence, Limited Presumption of Competence, and Presumption of Competence with Support. The General Presumption of Competence is a broad statement that assumes an individual with a disability has the same capacity to understand and make decisions as a non-disabled person. The Limited Presumption of Competence states that an individual with a disability has the ability to make decisions, but that decisions must be made with the support of family and professionals. Lastly, the Presumption of Competence with Support is a combination of the General and Limited Presumptions of Competence in which an individual with a disability is assumed to have the capacity to make decisions, but only with the guidance of a professional or family member.
