(a) File with the clerk of the county court a notice of appeal; and
(b) Deposit with the clerk of the county court a docket fee in the amount of the filing fee in district court.
(2) Satisfaction of the requirements of subsection (1) of this section shall perfect the appeal and give the district court jurisdiction of the matter appealed.
(3) The entry of a judgment or final order occurs when the clerk of the court places the file stamp and date upon the judgment or final order. For purposes of determining the time for appeal, the date stamped on the judgment or final order shall be the date of entry.
(4) In appeals from the Small Claims Court only, the appealing party shall also, within the time fixed by subsection (1) of this section, deposit with the clerk of the county court a cash bond or undertaking, with at least one good and sufficient surety approved by the court, in the amount of fifty dollars conditioned that the appellant will satisfy any judgment and costs that may be adjudged against him or her.
(5) A notice of appeal or docket fee filed or deposited after the announcement of a decision or final order but before the entry of the judgment or final order shall be treated as filed or deposited after the entry of the judgment or final order and on the day of entry.
(6) The running of the time for filing a notice of appeal shall be terminated as to all parties (a) by a timely motion for a new trial under section 25-1144.01, (b) by a timely motion to alter or amend a judgment under section 25-1329, or (c) by a timely motion to set aside the verdict or judgment under section 25-1315.02, and the full time for appeal fixed in subsection (1) of this section commences to run from the entry of the order ruling upon the motion filed pursuant to subdivision (a), (b), or (c) of this subsection. When any motion terminating the time for filing a notice of appeal is timely filed by any party, a notice of appeal filed before the court announces its decision upon the terminating motion shall have no effect, whether filed before or after the timely filing of the terminating motion. A new notice of appeal shall be filed within the prescribed time from the entry of the order ruling on the motion. No additional fees are required for such filing. A notice of appeal filed after the court announces its decision or order on the terminating motion but before the entry of the order is treated as filed on the date of and after the entry of the order.
(7) The party appealing shall serve a copy of the notice of appeal upon all parties who have appeared in the action or upon their attorney of record. Proof of service shall be filed with the notice of appeal.
(8) If an appellant fails to comply with any provision of subsection (4) or (7) of this section, the district court on motion and notice may take such action, including dismissal of the appeal, as is just.
