What is the deadline to file an appeal against a Thai civil court judgment and what steps are involved?

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. 

Regarding your inquiry about appealing a civil court decision in Bangkok, please find the essential points below:

• 
  

  Deadline: You must file the appeal within one month from the date the judgment was read. If you need more time, a petition to extend this deadline must be filed before the initial period expires.

  
  


• 
  

  Grounds for Appeal: The appeal must be based on points of law or fact that were already raised during the initial trial. New issues generally cannot be introduced at this stage.

  
  


• 
  

  New Evidence: Generally, the Appeal Court does not allow new evidence. It can only be admitted under very limited and exceptional circumstances where you can prove that the evidence was unavailable during the original trial despite due diligence.

  
  


• 
  

  Legal Representation: Yes, it is highly recommended (and practically necessary) to hire a Thai lawyer. The appeal must be drafted in Thai, addressing specific legal errors in the judgment, and must comply with strict procedural requirements under the Civil Procedure Code.

  
  

To proceed, I will need to review the Full Judgment (คำพิพากษาฉบับเต็ม) of the Court of First Instance to assess the merits of your case for an appeal.

Would you like me to review the judgment and calculate your specific deadline?
