Okla. Stat. tit. 49, § 49-117: Notarial acts performed by officer of foreign nation or

multinational or international organization.

A. A notarial act has the same effect pursuant to the laws of

this state as if performed by a notarial officer of this state if

performed within the jurisdiction of and under authority of a

foreign nation or its constituent units or a multinational or

international organization by any of the following persons:

1. a notary public or notary;

2. a judge, clerk, or deputy clerk of a court of record; or

3. any other person authorized by the law of that jurisdiction

to perform notarial acts.

B. An "Apostille" in the form prescribed by the Hague

Convention of October 5, 1961, conclusively establishes that the

signature of the notarial officer is genuine and that the officer

holds the indicated office.

C. A certificate by a foreign service or consular officer of

the United States stationed in the nation under the jurisdiction of

which the notarial act was performed, or a certificate by a foreign

service or consular officer of that nation stationed in the United

States, conclusively establishes any matter relating to the

authenticity or validity of the notarial act set forth in the

certificate.

D. An official stamp or seal of the person performing the

notarial act is prima facie evidence that the signature is genuine

and that the person holds the indicated title.

E. An official stamp or seal of an officer listed in this

section is prima facie evidence that a person with the indicated

title has authority to perform notarial acts.

F. If the title of office and indication of authority to

perform notarial acts appears either in a digest of foreign law or

in a list customarily used as a source for that information, the

authority of an officer with that title to perform notarial acts is

conclusively established.
