Okla. Stat. tit. 12 § 140.1
When the court orders the transfer of a case upon a showing by a party that the venue is or should be in some other county, the clerk of the court shall prepare a transcript of all the papers filed, orders entered, and a bill of the costs accrued. The clerk shall collect a new filing fee and shall forthwith transmit by certified mail such files and transcript of the cause and the filing fee which shall be due to the clerk of the court to which transfer is ordered. Unless otherwise ordered by the court, the plaintiff shall be responsible for appropriate filing fees when a case is brought in the wrong venue and transferred to a court having proper venue. In all other instances, the moving party shall be responsible for fees. The fees for the transfer shall be paid within ten (10) days of the transfer order.
