Okla. Stat. tit. 18 § 583
Any fraternal beneficiary society incorporated under the laws of this state may change its corporate name on application by its governing body to the Insurance Commissioner of the state. The name selected shall not be such as will appear to be so near the name of any other association or society now doing business in this state as to cause confusion in the minds of the people, or to interfere with the corporate name of such existing association or corporation. On the approval of the Insurance Commissioner the Secretary of State shall cause an amended charter to issue, signed by the Governor and attested by the seal of state, changing the name of such beneficiary society in accordance with the recommendation of the Insurance Commissioner, and such change of name shall have the same effect as if originally set forth in the original articles of incorporation.
