Okla. Stat. tit. 10, § 10-1416: Liability for care and treatment

A resident at an institution named in Section 1406 of this title

is liable for his or her care and treatment. This claim of the

state for such care and treatment shall constitute a valid

indebtedness against the resident and his or her estate and shall

not be barred by any statute of limitations. At the death of the

resident this claim shall be allowed and paid as other lawful claims

against the estate. Persons making application for admission of an

individual with intellectual disability to the institution are also

liable for the care and treatment of the resident, provided that

such persons are legally obligated to support the resident. No

person shall be liable for care and treatment solely on the grounds

that the person has been appointed guardian of the resident.

Provided, further, that no admission or detention of an individual

with intellectual disability in the institution shall be limited or

conditioned in any manner by the financial status or ability to pay

of an individual with intellectual disability, his or her estate, or

any relative.
