Okla. Stat. tit. 36, § 36-2735.1: Service of process

A. Every society authorized to do business in this state shall

appoint in writing the Insurance Commissioner and each successor in

office to be its true and lawful attorney upon whom all lawful

process in any action or proceeding against it shall be served, and

shall agree in writing that any lawful process against it which is

served on said attorney shall be of the same legal force and

validity as if served upon the society, and that the authority shall

continue in force so long as any liability remains outstanding in

this state. Copies of the appointment, certified by said

Commissioner, shall be deemed sufficient evidence thereof and shall

be admitted in evidence with the same force and effect as the

original thereof might be admitted.

B. Service shall only be made upon the Commissioner, or if

absent, upon the person in charge of the Commissioner's office. It

shall be made in triplicate and shall constitute sufficient service

upon the society. When legal process against a society is served

upon the Commissioner, the Commissioner shall forthwith forward one

of the triplicate copies by registered mail, prepaid, directed to

the secretary or corresponding officer. No such service shall

require a society to file its answer, pleading or defense in less

than thirty (30) days from the date of mailing the copy of the

service to a society. Legal process shall not be served upon a

society except in the manner herein provided. At the time of

serving any process upon the Commissioner, the plaintiff or

complainant in the action shall pay to the Commissioner a fee of Ten

Dollars ($10.00).
