Okla. Stat. tit. 43A, § 7-104
In the case of a patient who has substantially impaired ability to provide adequate self care or custody and who has no home or relatives or friends able and willing to care for the patient, the superintendent prior to discharge from the facility shall make a reasonable effort to arrange an appropriate placement and necessary services for the patient. When necessary, the superintendent shall refer to other public or voluntary agencies for assistance; provided, nothing in this section or Section 7-102 of this title shall be construed as restricting the right of an adult patient, when such patient has not been found by a court to be incompetent, to determine the placement or residence of such patient upon discharge from a facility.
