An appeal is taken by obtaining an order therefor, within the delay allowed, from the court which rendered the judgment.
An order of appeal may be granted on oral motion in open court, on written motion, or on petition. This order shall show the return day of the appeal in the appellate court and shall provide the amount of security to be furnished, when the law requires the determination thereof by the court.
When the order is granted, the clerk of court shall mail a notice of appeal to counsel of record of all other parties, to the respective appellate court, and to other parties not represented by counsel. The failure of the clerk to mail the notice does not affect the validity of the appeal.
