1. Never criticise the monarchy

Thailand's lèse-majesté law (Section 112 of the Criminal Code) makes it a criminal offence to defame, insult, or threaten the King, Queen, Heir Apparent, or Regent. Social media posts and reposting content are included. Foreign visitors are not exempt.

Where: Legal
Cost: 3–15 years imprisonment per count
Tip: Avoid any discussion of the royal family in public, online, or in taxis. Do not share memes or news articles about royals while in Thailand.

2. Do not step on or disrespect Thai currency

Thai baht notes and coins carry the King's image. Stepping on a coin is considered offensive and is technically illegal. Tearing or defacing notes is also illegal.

Where: Legal
Cost: Up to 10 years imprisonment
Tip: If you drop a coin, pick it up without stepping on it. Place money in the tray when paying rather than handing it directly.

3. Remove shoes before entering temples and many homes

All Buddhist temples (wats) require shoes to be removed at the entrance. The same applies to many Thai homes, guesthouses, and shops. Wearing shoes inside is deeply disrespectful.

Where: Religious
Tip: Wear slip-on shoes when temple-visiting. Socks are fine. Look for a pile of shoes outside as your cue.

4. Women must not touch monks or pass items directly to them

Theravada Buddhist monks take vows forbidding physical contact with women. Items should be placed on a cloth or passed via a male companion.

Where: Religious
Tip: On public transport, give up a seat next to a monk. On the morning alms round, women must not touch a monk's hand or bowl.

5. Dress code is mandatory at major temples

Wat Phra Kaew and Wat Pho strictly enforce dress codes: shoulders and knees must be covered. Guards turn away visitors who are not appropriately dressed.

Where: Etiquette
Cost: Entry denied
Tip: Pack a lightweight scarf or sarong. It solves the problem at every temple across Thailand.
