Thai culture is easy to admire and easy to get wrong in small ways that add up. This is the residents' version rather than the tourist version: how greetings and names actually work, what the Constitution and the Criminal Code say about the monarchy, the monk and temple rules that are genuinely observed, the Fine Arts Department permission you need to take a Buddha image home, why your lease is dated 2569, and what to do about the spirit house standing on your plot.

The wai is palms pressed together in front of the chest, fingertips rising and the head bowing a little as the seniority of the other person increases. It works as a greeting, a thank-you, an apology and a goodbye. The highest form, thumbs at the brow, is reserved for monks and for images of the Buddha, not for people you meet at work.
The rule foreigners get wrong is the return. You return a wai from a peer or from someone senior to you. You do not need to return one from a child, or from staff greeting you at a hotel desk, a shop counter, a restaurant door or a condo lobby: a smile and a nod is the correct answer there, and solemnly returning every service wai marks you out as new rather than as respectful.
The spoken greeting is sawasdee, finished with the politeness particle that matches your own gender, not the listener's: khrap if you are male, kha if you are female. Thai attaches that particle to most sentences in polite speech, and using it is the single cheapest thing a beginner can do to sound courteous.
Wai protocol is convention rather than regulation. We found no Thai government source that sets it out, and we describe it here as custom.
Thai family names are unique by law. The Persons Name Act (No. 3), B.E. 2548 (2005), which amends the Person's Name Act of B.E. 2484 (1941), prohibits registering a surname that repeats one already conferred by the King or already on the register, and caps a newly created surname at ten Thai letters. Two unrelated Thai families essentially never share a surname.
That is why Thai surnames are long, unfamiliar and almost never spoken. The country runs on given names instead. Formal address is Khun plus the given name: Khun Somchai, not Khun Chaiyaporn-anything. It is the right form in an email, in a meeting, with a landlord, with an agent, and with someone twice your age.
Nearly everyone also carries a nickname, the chue len, usually one or two syllables and often unconnected to the legal name. Colleagues and friends use it constantly. You will meet people who introduce themselves only by it.
For a foreigner the safe pattern is simple: give your first name, use Khun plus their first name until told otherwise, and expect Khun plus your own first name back. The long registered name is the one that appears on a lease, a title deed, a work permit or a company document; the nickname never does.
Jai yen means cool heart, and it is the quality Thai social life prizes. Its opposite, jai ron, is a hot heart. Raising your voice, making a scene, or making another person look foolish in front of others does not produce a faster outcome here. It produces a slower one, because the person you embarrassed now has a reason to be unhelpful that has nothing to do with the problem.
Kreng jai is the companion idea: a reluctance to impose, to contradict, or to be the bearer of an unwelcome answer. It is why a colleague may not tell you a deadline is impossible, why a contractor may not say the part is unavailable, and why a tenant may not mention the leak until it is a ceiling. It is not evasion. It is consideration, aimed at you.
The workaround is structural, not confrontational. Ask open questions rather than yes-or-no ones. Ask what could go wrong or what would delay it. Give people a way to decline that does not require them to refuse you. Put the answer in writing afterwards so nobody has to repeat it.
Mai pen rai translates as never mind or it is nothing. It smooths over a great deal, and it is worth knowing that it is a social lubricant first and an agreement second.
This is the one area of Thai cultural life with direct legal weight, so it is worth stating precisely rather than vaguely.
The Constitution of the Kingdom of Thailand, B.E. 2560 (2017), Section 6, reads: The King shall be enthroned in a position of revered worship and shall not be violated. No person shall expose the King to any sort of accusation or action. Section 7 reads: The King is a Buddhist and Upholder of religions.
Separately, Section 112 of the Criminal Code provides that whoever defames, insults or threatens the King, the Queen, the Heir-apparent or the Regent shall be punished with imprisonment of three to fifteen years. Sourcing note: we could not find a current English text of Section 112 published on a Thai government domain in this pass. The wording above is as reproduced by ARTICLE 19 in March 2021, and the governing text is the Thai original.
In practice this covers what you write as well as what you say, and it covers social media. Images of the King appear on banknotes, on public buildings and on roadside portraits; treat them as you would treat any object of respect. Stepping on a dropped banknote to stop it blowing away is the classic accidental offence.
BAANLYY is a property portal, not a law firm, and nothing here is legal advice. If you have a specific question about Section 112 or about anything you have published, take it to a Thai lawyer rather than to a forum.
Two related customs are worth knowing. Cinemas play the royal anthem before the feature and the audience stands. The national anthem is broadcast at 08:00 and 18:00 in stations, parks and many public spaces, and people around you will stop and stand still until it finishes. We could not locate the published regulation behind the second practice, so we describe it as practice.
The 2017 Constitution, Section 67, says the State should support and protect Buddhism and other religions, and that in doing so it should promote education and dissemination of the principles of Theravada Buddhism and have measures to prevent Buddhism from being undermined. Thailand has no single established state religion in the European sense, but the constitutional text is explicit about Theravada Buddhism's place.
Monks are visible from dawn. The alms round, binthabat, happens in the early morning in every neighbourhood, and offering food is ordinary and welcome. One rule matters: under the Theravada monastic code a monk does not take an object directly from a woman's hand. The offering is placed on a cloth the monk sets down, or passed through a man. Nobody will be angry if you get it wrong, but they will notice.
The same logic runs through the rest of monk etiquette. Do not touch a monk. Do not sit physically higher than one. Buses and the Bangkok trains have seats reserved for monks, and they are respected; if you are sitting in one and a monk boards, move.
Phansa, often called Buddhist Lent, is the three-month rains retreat beginning the day after Asalha Bucha, when monks stay at a single temple. Some Thais give up alcohol for the whole period. Alcohol sales are restricted on the major Buddhist holy days, and those rules have changed more than once recently, so we keep them on one page rather than repeating a figure that will age: see our guide to alcohol rules and nightlife.
Thailand is not only Buddhist. Islam, Christianity, Hinduism and Chinese folk religion all have long-settled communities, and the south in particular is substantially Muslim. We did not confirm a current religious-demography percentage from a Thai government source in this pass, so we print none here.
Dress is the part that is genuinely enforced rather than merely hoped for. Shoulders and knees covered, for everyone. The major sites are strict about it, and many keep cover-ups at the entrance, sometimes against a deposit. Turning up in a vest and shorts at a first-tier temple means queueing twice.
Take your shoes off before entering an ordination hall or a viharn. Socks are normally fine. At older temples and traditional houses, step over the raised threshold rather than on it.
Sit with your feet tucked behind you, and never with the soles pointing at a Buddha image, a monk or another person. Do not climb on a statue, a chedi or a ruin, and do not pose with an arm around a Buddha image for a photograph. Ask before photographing anybody at prayer.
Keep your voice down, switch your phone to silent, and follow whatever the Thai visitors around you are doing. That last instruction covers almost every case this page does not.
A Buddha image is a religious object, not an ornament. Placing one on the floor, in a bathroom, or facing a bed reads badly to a Thai visitor, and a Buddha tattoo on the lower body or the leg reads worse. Our guide to tattoos and sak yant covers the tattoo question in detail.
There is also a legal dimension that catches people at the airport. The Thai Customs Department lists Buddha images, artifacts and objects, and antiques among goods that require written permission from another agency before they leave the country, and it names the issuing authority: the Fine Arts Department, through its single-window service. A souvenir bought in a market is not automatically exempt.
Being precise about what we actually read: the Customs page we checked states the requirement and the issuing authority, and gives no size threshold. The rule widely repeated on travel sites, that images under about twelve centimetres are fine, does not appear there. Treat it as unverified, apply to the Fine Arts Department if you want to take an image home, and if that is not practical, do not buy one to export.
Two rules prevent most accidental offence. The head is the highest and most sacred part of the body, so do not touch anyone's head, including a child's, however affectionately it is meant. The feet are the lowest, so do not point them at a person or an image, do not push a door or nudge an object with a foot, do not put your feet on a desk or a seat, and do not step over a person or over food laid on the floor.
Shoes come off indoors: in homes always, in many small offices, in clinics, in some shops, and at the door of a great many condominium units. A rack of shoes outside a front door is normal and nobody touches them. Slip-on shoes are the practical footwear for living here, which is why so many residents own a pair they can lose without grief.
Physical contact between strangers is limited. Public affection between couples is low-key, and a display that would pass unremarked in Europe will draw attention here. Same-sex friends holding hands or linking arms, by contrast, is entirely unremarkable and carries no romantic reading. Thailand's practical acceptance of LGBTQ life is covered on its own page.
Handing and receiving: two hands, or the right hand with the left touching the forearm, for anything given to someone senior. Money, business cards and documents all benefit from it.
Thailand's official year is the Buddhist Era. Add 543 to the Gregorian year: 2026 CE is 2569 BE. This is not a ceremonial flourish. It is the year that appears on Thai identity cards, on land title deeds, on company registration documents, on court papers, on bank forms and in the Thai-language half of a bilingual lease.
Thai statutes are cited the same way, which is why every law named on this page carries two years. The Constitution is B.E. 2560 (2017). The Customs Act is B.E. 2560 (2017). The Persons Name Act amendment is B.E. 2548 (2005). Subtract 543 and the Gregorian year falls out.
There is one trap, and it only bites on old documents. The Thai year began on 1 April until the start of 1941, when 1 January became the first day of B.E. 2484. For a date between 1 January and 31 March in a document predating that change, the offset is 542, not 543. We could not find a Thai government page stating the conversion rule in English; the 1941 change and the 542 offset are taken from the general reference cited below, and anything turning on a pre-war date is worth checking with a Thai lawyer rather than arithmetic.
If you are reading a lease or a title deed for the first time, the year is the least of it, but it is the detail that makes people think they are looking at the wrong document.
A Thai meal is shared. Dishes go in the middle, rice is individual, and you move small amounts from the communal dishes onto your own rice a few spoonfuls at a time rather than building a plate at the start. Take from the side of the dish nearest you.
The spoon is the main utensil and lives in the right hand. The fork lives in the left and exists to push food onto the spoon; it does not go into the mouth. Chopsticks are for noodle dishes and Chinese-Thai food, not for a plate of rice.
There is usually a host, and the person who did the inviting generally pays for the table. Offering to contribute is gracious even when it is waved away, and splitting a bill item by item is unusual among friends. Wait for the most senior person to begin.
If you are new to what is on the table, our guides to Thai food and dining and to street food are the practical next step.
Thai working life is relationship-first and openly hierarchical. Greet the most senior person present first. Exchange business cards with two hands, read the card before you put it away, and do not slide it into a back pocket in front of the person who gave it to you.
Disagreeing with a senior person in front of an audience costs them face and costs you the relationship, which is a poor trade for being right in a meeting. Raise the difficult thing privately, in a smaller room, framed as a question.
Yes frequently means I have heard you. It is not dishonesty; it is kreng jai meeting a direct question. Confirm decisions in writing, ask what might delay the thing rather than whether it will happen, and build in the possibility that the answer changes once somebody senior has been consulted.
Meals do work that meetings do not. An invitation to eat is usually the real meeting, and declining several in a row is read as distance rather than as busyness.
Shoes come off at the door of a Thai home and of many condominium units. Expect a rack in the corridor and leave yours with the others.
Neighbours rarely complain to your face. A Thai neighbour irritated by noise, a balcony smell or a repeated 2am arrival will usually raise it with the juristic person or the building office rather than knock, so a polite notice under your door may be the first you hear of a problem that has been running for a month. Reading it as an escalation is the wrong instinct; it is the normal first step.
Almost every plot of land, house, shop, office and condominium development in Thailand has a spirit house, the san phra phum: a small shrine, usually raised on a pillar, for the spirit of the place. It receives offerings of food, drink, flowers and incense, sometimes daily. You will see them tended in the car parks of glass office towers.
The practical rule for a foreign owner or tenant is to leave it alone and let it be tended. Moving, neglecting or disposing of a spirit house is taken seriously by the Thai people around you, and it is not a decision to make by yourself. Where development genuinely requires one to be relocated, that is done deliberately and with a ceremony. This is custom rather than statute: we found no Thai law governing spirit houses, and we are describing what is done, not what is required.
Songkran, the Thai New Year, runs 13 to 15 April. UNESCO inscribed Songkran in Thailand, traditional Thai New Year festival on the Representative List of the Intangible Cultural Heritage of Humanity in 2023, at the eighteenth session of the committee, under reference 01719. UNESCO's own description puts water at the centre for a reason that the street version can obscure: pouring water signifies cleansing, reverence and good fortune, and the festival is built around bathing Buddha images, paying respect to elders and returning to family.
The part the brochures leave out is the road toll. Thailand's Road Safety Operations Centre, under the Department of Disaster Prevention and Mitigation, publishes daily figures across the holiday period it calls the seven dangerous days. For 10 to 16 April 2026 it recorded 1,242 crashes, 1,200 people injured and 242 deaths, with motorcycles involved in 64.55 per cent of crashes and speeding the leading contributing factor at 40.65 per cent. If you ride a motorbike, Songkran is the week to leave it parked.
Loi Krathong, when small decorated floats are set on the water, falls on the full moon of the twelfth month of the Thai lunar calendar, so its Gregorian date moves every year. Its northern counterpart, Yi Peng in Chiang Mai, is the sky-lantern festival, and lantern releases near airports are restricted on aviation-safety grounds.
Many Thai holidays are lunar and therefore move, and several close banks and government offices outright. Rather than print a date list that ages, we keep the calendar on our public holidays page and our guide to Thai holidays, and what is actually on in a given month on the events hub.
Culture pages are unusually easy to pad with things that sound right. These are the points this page deliberately leaves open rather than filling in, and why.
You return a wai offered by a peer or by someone senior to you. You do not need to return one from a child, or from staff greeting you at a hotel desk, shop counter or condo lobby, where a smile and a nod is the normal and correct response. The highest wai, with the thumbs at the brow, is for monks and Buddha images rather than for people you meet socially.
Use Khun followed by their given name, not their surname: Khun Somchai. Thai law makes family names unique to a family and caps a new surname at ten Thai letters under the Persons Name Act (No. 3), B.E. 2548 (2005), which is why surnames are long, unfamiliar and rarely spoken. Most people also have a short nickname used by friends and colleagues. Give your own first name and expect Khun plus that name in return.
Not without permission. The Thai Customs Department lists Buddha images, artifacts and antiques among goods requiring written permission from another agency before export, and names the Fine Arts Department as the issuing authority through its single-window service. The Customs page states no size threshold, so the widely repeated claim that small images are exempt is not something we can verify. Apply to the Fine Arts Department, or do not buy an image to take out of the country.
The Constitution of B.E. 2560 (2017), Section 6, places the King in a position of revered worship and provides that no person shall expose the King to accusation or action. Section 112 of the Criminal Code provides that defaming, insulting or threatening the King, Queen, Heir-apparent or Regent carries imprisonment of three to fifteen years. It applies to what you publish online as well as what you say. BAANLYY is not a law firm and this is not legal advice; take a specific question to a Thai lawyer.
Thailand's official year is the Buddhist Era, which is the Gregorian year plus 543, so 2026 CE is 2569 BE. It appears on identity cards, land title deeds, company documents, court papers and the Thai half of a bilingual lease, and Thai statutes are cited the same way. One exception applies only to old documents: 1 January became the start of the Thai year in 1941, so a January to March date in an earlier document converts with 542.
Shoulders and knees covered, for men and women alike. Major temples enforce this at the gate and many lend cover-ups, sometimes against a deposit. Shoes come off before you enter an ordination hall or viharn, socks are usually fine, and you sit with your feet tucked behind you so the soles never point at a Buddha image, a monk or another person.
Under the Theravada monastic code a monk does not receive an object directly from a woman's hand. The offering is placed on a cloth that the monk lays down, or handed over through a man. The same family of rules explains why you do not touch a monk or sit higher than one, and why buses and the Bangkok trains keep seats reserved for monks.
Leave it where it is and let it be tended. The san phra phum is a shrine for the spirit of the place and sits on almost every Thai plot, house, shop and condominium development. Moving, neglecting or disposing of one is taken seriously, and where development genuinely requires relocation it is done deliberately and with a ceremony. This is custom rather than law, so the constraint is social rather than legal, but it is a real one.
Etiquette is half of it; the other half is knowing what you are looking at. Our temple guide covers Thailand province by province — what each temple holds, its opening hours, admission, dress code and photography rules, with the documented record kept separate from what tradition holds.
Primary and official sources are cited above. Government rules, fees and procedures in Thailand change over time and vary by office; always confirm current requirements with the relevant authority before relying on them. BAANLYY never takes paid placement in editorial content.
Find a neighbourhood that fits your life in Thailand.
Customs vary by region, generation and setting, and this page describes the general case. Where a point has legal weight it is cited to the statute or the authority that publishes it, and where we could not confirm something it is listed above rather than smoothed over. BAANLYY is a property portal and not a law firm; nothing here is legal advice. When in doubt, watch what the Thai people around you are doing and follow their lead.
