Okla. Stat. tit. 84, § 84-41: Persons who may make a will - Persons subject to

guardianship or conservatorship.

A. Every person over the age of eighteen (18) years of sound

mind may, by last will, dispose of all his estate, real and

personal, and such estate not disposed of by will is succeeded to as

provided in this title, being chargeable in both cases with the

payment of all the decedent's debts, as provided in Title 12 of the

Oklahoma Statutes.

B. The appointment of a guardian or a conservator does not

prohibit a person from disposing of his estate, real and personal,

by will; provided, that when any person subject to a guardianship or

conservatorship shall dispose of such estate by will, such will must

be subscribed and acknowledged in the presence of a judge of the

district court. The judge before whom the will is subscribed and

acknowledged shall attest to the execution of the will but shall

have neither the duty nor the authority to approve or disapprove the

contents of the will. Subscribing and acknowledging such will

before a judge shall not render such will valid if it would

otherwise be invalid.
