In NY state practice, you have 30 days from service upon you of a notice of entry of the order or judgment against you within which to serve and file your Notice of Appeal. If the opposing party has not served you with notice of entry, and if you want to appeal, you may yourself serve a proper notice of entry upon the opposing party, and that, too, will start your 30-day period. You must double check with your adversary to make sure he or she did not serve you with a notice of entry.
