§12-990A.
   
   A. An appeal to the Supreme Court of Oklahoma, if taken, must be
   commenced by filing a petition in error with the Clerk of the Supreme
   Court of Oklahoma within thirty (30) days from the date a judgment,
   decree, or appealable order prepared in conformance with Section 696.3
   of this title is filed with the clerk of the trial court. If the
   appellant did not prepare the judgment, decree, or appealable order,
   and Section 696.2 of this title required a copy of the judgment,
   decree, or appealable order to be mailed to the appellant, and the
   court records do not reflect the mailing of a copy of the judgment,
   decree, or appealable order to the appellant within three (3) days,
   exclusive of weekends and holidays, after the filing of the judgment,
   decree, or appealable order, the petition in error may be filed within
   thirty (30) days after the earliest date on which the court records
   show that a copy of the judgment, decree, or appealable order was
   mailed to the appellant.
   
   B. The filing of the petition in error may be accomplished either by
   delivery or by certified mail with return receipt requested to the
   Clerk of the Supreme Court. The date of filing or the date of mailing,
   as shown by the postmark affixed by the post office or other proof
   from the post office of the date of mailing, shall constitute the date
   of filing of the petition in error. If there is no proof from the post
   office of the date of mailing, the date of receipt by the Clerk of the
   Supreme Court shall constitute the date of filing of the petition in
   error.
   
   C. The Supreme Court shall provide by rule, which shall have the force
   of statute, and be in furtherance of this method of appeal:
   
   1. For the filing of cross-appeals;
   
   2. The procedure to be followed by the trial courts or tribunals in
   the preparation and authentication of transcripts and records in cases
   appealed under this act; and
   
   3. The procedure to be followed for the completion and submission of
   the appeal taken hereunder.
   
   D. In all cases the record on appeal shall be complete and ready for
   filing in the Supreme Court within the time prescribed by rule.
   
   E. Except for the filing of a petition in error as provided herein,
   all steps in perfecting an appeal are not jurisdictional.
   
   F. 1. If a petition in error is filed before the time prescribed in
   this section, it shall be dismissed as premature; however, if the time
   to commence the appeal accrues before the appeal is dismissed, the
   appellant may file a supplemental petition in error, without the
   payment of any additional costs. Such supplemental petition in error
   shall state when the time for commencing the appeal began and shall
   set out all matters which have occurred since the filing of the
   original petition in error and which should be included in a timely
   petition in error. When a proper supplemental petition in error is
   filed, the appeal shall not be dismissed on the ground that it was
   premature.
   
   2. If an appeal is dismissed on the ground that it was premature, the
   appellant may file a new petition in error within the time prescribed
   in this section for filing petitions in error or within thirty (30)
   days after notice is mailed to the parties which states that the
   appeal was dismissed on the ground that it was premature, whichever
   date is later. A notice that an appeal was dismissed on the ground
   that it was premature shall include the date of mailing and the ground
   for dismissal.
   
   G. 1. No designation of record shall be accepted by the district court
   clerk for filing unless it contains one of the following:
   
   a. where a transcript is designated: A signed acknowledgment from the
   court reporter who reported evidence in the case indicating receipt of
   the request for transcript, the date received, and the amount of
   deposit received, if applicable, in substantially the following form:
   I, ________, court reporter for the above styled case, do hereby
   acknowledge this request for transcript on this ____ day of____, 19__,
   and have received a deposit in the sum of $____. , or
   
   b. where a transcript is not designated: A signed statement by the
   attorney preparing the designation of record stating that a transcript
   has not been ordered and a brief explanation why, in substantially the
   following form: I, ________, attorney for the appellant, hereby state
   that I have not ordered a transcript because:
   
   (1) a transcript is not necessary for this appeal, or
   
   (2) no stenographic reporting was made.
   
   2. This section shall not apply to counter-designations of record
   filed by appellees.
