The trial court record, including any transcript of proceedings, shall be filed with the clerk for this court in the respective county 20 days from the filing of the Notice of Appeal. Preparation of the record, including any transcript of proceedings, shall be given priority over the preparation of the records in all other cases. Extensions for the filing of the record shall not be granted, except in the most extreme circumstances and only in the interest of justice.
When the employment of an acceptable substitute for the transcript or the entire record would facilitate the submission of the trial court record to the clerk in less than 20 days, counsel for both sides should consider following the procedures set forth in Ohio App.R. 9(C) or 9(D).
