You left a one-star review. You warned a friend about a bad landlord. You posted in a Facebook expat group about a company that scammed you. In most countries, this is free speech. In Korea, it could be a criminal offense — and the most shocking part is that it doesn't matter if every word you said was true.

Korea Has Criminal Defamation. Yes, Criminal.

Most foreigners come from countries where defamation is a civil matter — someone sues, you pay damages, life goes on. Korea is different. Under the Korean Criminal Act, defamation is a criminal offense punishable by:

And here is the part that makes foreigners' jaws drop: Article 310 states that truth is a defense — but only if the statement was made solely for the public benefit. If a court decides your true statement wasn't sufficiently in the public interest, you can still be convicted.

Real Situations That Lead to Criminal Complaints

These aren't hypotheticals — they result in actual complaints filed in Korea every year:

"But I Have Proof It's True"

This is what almost every client says first. Under Korean law, if you can prove the statement was true and made for the public benefit, you have a defense, and courts do acquit on these grounds. But you still have to go through the entire criminal process to get there — police investigation, possible prosecutor interrogation, potential indictment, possible trial. Even if you're ultimately acquitted, the process itself is expensive, slow, and terrifying — especially in a foreign language without a lawyer.

Online Defamation Is Even More Serious

Korea has a separate law for online defamation under the Information and Communications Network Act. It carries penalties of up to 3 years for true statements made without public benefit, or up to 7 years for false statements.

Seven years. For a Facebook post.

This covers anything published online: social media, review platforms, online communities, blog posts, YouTube comments, KakaoTalk group chats — even direct messages that get shared.

How to Protect Yourself

  1. Ask if it's truly in the public interest. Exposing widespread fraud or a public-safety issue is a stronger claim than a personal grievance.
  2. Stick to facts, not opinions. "This company owes me three months of salary" is factual. "This company is run by criminals" is an opinion that opens you to liability.
  3. Keep your evidence. Contracts, messages, receipts, records. If you make a claim, be ready to prove it.
  4. Consider the platform. A private message to one friend carries far less risk than a public post to a 10,000-member group.
  5. If you've already been complained against, get a lawyer immediately. Do not respond to a police summons alone.

If You've Already Received a Police Summons

First, don't panic. Many defamation complaints in Korea are filed as pressure tactics — to silence critics or gain leverage in a separate dispute — and not all result in prosecution. But how you respond early matters enormously:
