Okla. Stat. tit. 12, app 1 R. 1.64
The record shall be designated and prepared in the same manner as that prescribed for perfecting an appeal from a final judgment or final order of the district court. See Rules 1.28 through 1.34.
If transcripts are ordered the Notice of Completion of Record (Rule 1.301, Form No. 12) shall be filed within sixty (60) days of the filing of the interlocutory order. The record shall consist of the same items as in appeals from final decisions of a district court (Part II of these Rules, See Rule 1.33).
If a transcript is designated for inclusion in the record on appeal, it shall be the responsibility of the trial court to expedite the preparation thereof by such orders, prospective or retrospective in effect, as may seem proper to assure the earliest possible completion of the record. Appellant bears the burden of monitoring the preparation of the record and requesting the appropriate relief from the trial court for the timely preparation and completion of the record.
