KakaoTalk Voice Message Evidence, General Approach When It Is Missing From the Export
When you export a text chat, voice messages are often not in the file. This page only summarizes general points to consider in that case.
Not legal advice. This page is general information. Whether a court admits or relies on a chat is for the court; convokeep does not promise admission or any outcome. What is needed differs by case, so check with a lawyer or the Korea Legal Aid Corporation (☎132).
Does the export file contain the voice?
A text export may keep only a marker that a voice message existed, not the voice itself, or nothing at all. We could not confirm this from an official source, so open your exported file and check. convokeep turns text chats into a PDF and does not include audio.
How do I keep the voice?
First, do not delete that voice message from your device. Whether the chat room lets you save or share voice differs by app version. If you saved it, do not edit the original file; work from a copy.
May I record?
Secretly recording another person's call or conversation in which you did not take part may be restricted by law. When and how it is allowed differs by case, so ask a lawyer. This page does not recommend any method.
What about the written record?
You can export the written chat before and after the time the voice messages were exchanged. Organize it into a PDF with dates and times, and you can talk to a lawyer about how it might be used.
How do I submit the voice?
The submission format differs by court, agency and other party. Ask the court or your lawyer first.
