To start the appeals process, you and your lawyer must file a notice of appeal. The appellate court will review the trial record and written briefs, and may hear oral arguments, to determine if the lower court made a legal error. There will be no new trial or witnesses called to testify. If the appellate court finds that your argument is valid, the judgment may be reversed or modified, and your case may return to court for a new trial or for entry of the correct judgment.
