A Notice of Appeal is a formal document filed by a defendant or their legal representative to initiate the appeals process after a criminal conviction or sentence. It signals the intention to challenge the trial court’s decision in a higher court. The notice must be filed within a strict time limit, often within 30 days of sentencing. It does not outline the grounds of appeal but preserves the right to appeal. Filing a timely and properly formatted Notice of Appeal is crucial, as missing the deadline can forfeit the opportunity to have a conviction or sentence reviewed and potentially overturned.
