For many civil cases, the case must be appealed within 30 days from the date of the judgment. However, if the other party filed an appeal, you may only have 14 days to file an appeal. In criminal cases, the defendant may only have 14 days to file an appeal. If these time limits are not met, the party may lose his or her right to appeal the decision. It is important that you know what your time limit to appeal is so you can reserve your rights.
