Is prostitution legal in Thailand? — Koh Samui
Grey, in the Thai way: the transaction and the barfine (400–1,000 baht here) are lawful, the public and organised sides are prohibited under the 1996 Act, and enforcement arrives as venue regulation. Samui's 2026 version of it is unusually concrete. In mid-March the bars were ordered shut by 22:00 under a new government rule — locals told the March report the change landed in a single week — which is the state squeezing the visible layer without touching the exchange itself.
18+ only. Informational; legality varies by country.
How the grey plays on an island
The visible market (bars, go-gos) carries the regulatory weight — curfews, licences, the periodic rule changes — while the dispersed market (massage shops, freelancers, apps) operates in the same legal grey with none of the signage. Nothing we track shows client-side attention at all on Samui: the only enforcement anyone has logged is the bar-closure order, and the one violent incident on file, February's robbery attempt, is general nightlife crime rather than a vice action. The statute's sharp national edges — 2–6 years where under-15s figure, 1–10 for trafficking — sit where they always sit: on the exploitation layer, not the bar bill.
The absolute lines are the national ones, 18+ and anything organised around minors or coercion, and the practical frame for a visitor is the same as Pattaya's: legal risk close to nil, the real exposure in billing and health, and an island small enough that reputation (the named shops, the reviewed freelancers) works the way licences do elsewhere.

Questions
Does local law apply to tourists?
Yes. The law of the country you are physically in applies regardless of citizenship, and some countries additionally prosecute their citizens for specific offences committed abroad. Ignorance of local law is not a defence anywhere.
What are the penalties in Thailand?
Penalties depend on what exactly is prohibited — selling, buying, organising or soliciting — and vary by region and over time. Where buying is criminalised, fines and mandatory courses are typical; where organising is the offence, venues and intermediaries carry the risk. Verify the current law for your specific situation before relying on anything.
How do I check the current situation in Thailand?
The general status is described above; for how the law is actually applied, recent changes and city-level specifics — ask.
