Okla. Stat. tit. 12, app 1 R. 1.30
If no stenographic report of the evidence or proceedings at a hearing or trial was made or if a transcript of the reporter's notes cannot be prepared or where the judgment involves an involuntary loss of liberty, personal freedom or incarceration and where the appealing party is an indigent, the party desiring to take the appeal under these rules (or any other party) may prepare a statement of the evidence or proceedings in the narrative form from the best available means including the party's recollection for use in lieu of a stenographic transcript.
Where no stenographic report was made, this statement shall be filed with the court clerk and submitted to the opposite parties within ten (10) days after the filing of the petition in error; where a transcript of the court reporter's notes cannot be prepared, this statement shall be filed with the court clerk and submitted to the opposite parties within twenty (20) days after the party desiring to appeal discovers that the reporter's notes are unavailable or cannot be transcribed. These time limits may be extended by the trial court for good cause shown. The statement that is filed shall contain a certificate that copies have been submitted to the opposite parties. The narrative shall (1) be sworn to before an officer authorized by law to administer oaths (2) set forth that Rule 1.30 is relied on (3) inform the opposing party of the time and method for objections or amendments, and (4) advise the opposing party of the consequences of failure to object or move for proposed amendments. The opposite parties may object or propose amendments to the statement within ten (10) days after receipt. Thereupon, the statement, and any objections thereto, or proposed amendments shall be submitted, upon due and advance notice to all parties, to the trial judge for settlement and approval and as settled and approved shall be included by the clerk in the record on appeal. All narrative statements must be signed by the trial judge prior to submission to the Supreme Court, regardless of whether an objection or amendment was filed in the trial court.
Use of the narrative statement must be noted on the designation of record.
