I recently lost a civil case in Bangkok and want to appeal the decision. I’m unsure about the appeal deadline, required grounds for appeal, and whether I can present new evidence. Do I need to hire a Thai lawyer to file and represent me on appeal?

Hello. Sorry to hear about your loss in civil court. You have 30 days from within to extend the deadline to appeal or to file an appeal. Most of the time at least one extension will be filed in order to have sufficient time to prepare the appeal. Yes, unless you are an expert on appeal proceedings and capable of writing in proper, legal Thai languagem you should engage a law firm to represent you on appeal.
