Notice of Appeal is a formal notice served by the appellant on the court and the parties involved informing them of the appellant’s intention to request review of a lower court's order. It is the initial step in the appeals process. It informs the court and the party in whose favor a judgment or order has been made that the unsuccessful party seeks a review of the case. Failure to file a notice of appeal according to the statutory requirements will preclude appeal. Generally it shall be filed within 60 days after the rendition of the judgment. The nature of this notice varies from country to country and from court to court within a country.
