Okla. Stat. tit. 6 § 2022
Any credit union may, with the approval of the State Credit Union Board, merge with another credit union under the existing charter of the other credit union, pursuant to any plan agreed upon by the majority of the board of directors of each credit union joining in the merger, and approved by the affirmative vote of a majority of the members of the merging credit union present at a meeting of the members duly called for such purpose. After agreement by the directors and approval by the members of the merging credit union, the president and secretary of each credit union shall execute a certificate of merger, which shall set forth all of the following:
Such certificates and a copy of the plan of merger agreed upon shall be forwarded to the Bank Commissioner who shall, upon approval of the State Credit Union Board, certify and return them to the merging credit union and the surviving credit union within sixty (60) days. The merging credit union shall cause a copy of the certificate of merger, duly certified to by the Bank Commissioner, to be filed in the office of the Secretary of State forthwith. Unless otherwise provided in the certificate of merger, the merger shall be deemed effected upon such filing of the certificate and the merging credit union shall cease to exist.
Upon any such merger so effected, all property, property rights, field of membership and interest of the merged credit union shall vest in the surviving credit union without deed, endorsement or other instrument of transfer, and all debts, obligations and liabilities of the merged credit union shall be deemed to have been assumed by the surviving credit union under whose charter the merger was effected.
This section shall be construed, whenever possible, to permit a credit union chartered under any other act to merge with one chartered under this act, or to permit one chartered under this act to merge with one chartered under any other act.
