A notice of appeal is a formal document filed by a party to initiate the appellate process after a final judgment has been rendered in a trial court. This document signifies the intent to seek review of the lower court's decision, and it must be filed within a specific timeframe to ensure that the appeal is considered. The notice of appeal connects to important procedural rules that determine when appeals can be made, as well as the requirements for filing such notices, ensuring that parties follow proper channels for seeking appellate review.
