The Faux Pas Tourists Need To Know About That Carries A Years-Long Prison Sentence In Thailand

Traveling to Thailand any time soon? Before you go ahead and dive into all of the fun planning and packing parts of the trip — like picking out the best beaches to visit for sun, sand, and serenity, looking into what temples you want to explore, and practicing with how spicy you might want your food — there's more thing to be aware of before jetting off. Specifically, there's one unexpected custom that first-time travelers should be aware of that's recently made headlines for the potentially severe consequences it can lead to if ignored: the local restrictions related to discussing Thailand's monarchy.

Put simply, as part of Thailand's incredibly strict lèse-majesté law, which was enacted in 1980 and enforced under Article 112 of Thailand's criminal code. Local legislation essentially deems it illegal to criticize, insult, or defame the Thai monarchy in any way. Per the code, any person who "defames, insults or threatens the King, the Queen, the Heir-apparent or the Regent" is essentially breaking the law and "shall be punished with imprisonment." But what does "defaming" or "insulting" actually entail? Well, according to past cases, punishable offenses include everything from sharing critical social media posts to amplifying content from international media that discusses the monarchy, wearing clothes deemed disrespectful, or even liking Facebook posts that authorities consider offensive to the royal family. This ultimately makes trying to decipher what actually constitutes a punishable offense very broad.

While it might seem like an overly strict rule to foreigners, the harsh truth is that breaking this law doesn't just result in a minor fine or slap on the wrist. Depending on circumstances, anyone caught violating the law can face anywhere between three to 15 years in prison, with some people receiving decades-long sentences as punishment. Worse yet, this rule applies to everyone in Thailand, including visitors.

Thailand's lèse-majesté law works completely differently from most legal systems in most other countries. Unlike regular defamation laws, where the affected person must file the complaint, any Thai citizen can actually report you for perceived insults to the monarchy. Then, once reported, local police must investigate every accusation –– no matter who made it or how minor it seems.

If you're charged with a crime, it's likely that you'll have to spend a couple of months in jail before your trial even begins. This, because most Thai courts are known for denying bail in these cases, claiming they have serious concerns about you leaving the country or committing another (potentially worse) offense.

From there, the actual legal process also offers very few protections for the accused. In most cases, trials typically happen behind closed doors with little to no transparency. Some cases even end up in military courts instead of regular civilian ones, which means that the accused have even fewer legal rights than normal. Ultimately, the entire approach shows just how seriously Thailand takes things when it comes to protecting the royal family's image and their well-being. After all, to most locals, this law isn't just about showing respect — it's to ensure the royals' honor and safety, too.

Thailand's approach to protecting its royal family has recently made headlines around the world for its strictness. In January 2024, The New York Times reported that Mongkhon Thirakhot, a local Thai political activist, received a 50-year prison sentence for sharing 27 social media posts across two months with content from international sources — like John Oliver's "Last Week Tonight" and a BBC documentary — that authorities ultimately deemed offensive to the monarchy. This is the harshest penalty to date for under Thailand's lèse-majesté law. Beyond that, even foreigners have been hit with consequences. Most recently, in April 2025, Paul Chambers, a U.S. lecturer and academic, was arrested (and had his visa revoked) on lèse-majesté charges related to a webinar he'd participated in centered around Thailand's military and police forces (via The New York Times).

That said, when it comes to staying out of trouble, the best approach is to simply avoid any and all discussions, jokes, or comments about the Thai monarchy in public or online. Along with that, experts also recommend that travelers and tourists don't share or react to any social media content about them, and that they're cautious about wearing any clothing or accessories that could be potentially interpreted as mocking royal symbols.

Even the way you handle Thai money matters under these strict laws. So, while you might be used to treating cash a little more casually back home, Thai currency requires an extra level of care because it features the King's image. This essentially means that things like stepping on, crumpling, or ripping Thai bills are considered disrespectful. Instead, try to keep your money neatly folded in your front pocket or wallet, and hand it over face-up with your right hand whenever you're paying for something.
