Practising law in Thailand as a foreign lawyer

No route for foreign-qualified lawyersLimited home-law practice is possible

Thai nationality is a condition of the lawyer's licence, so a foreign lawyer cannot become a licensed Thai lawyer. A limited licence for advising on foreign and international law is possible, and a work permit is needed as well.

Rules change. This page describes the kinds of route that exist. The regulator listed under “Official sources” publishes the current requirements, fees and dates, so always confirm with them. This is general information, not legal advice.

The routes

Foreign legal consultant (limited licence)

For: Foreign lawyers who want to advise on foreign and international law in Thailand.

Apply for the limited licence that allows advice on foreign and international law. The Lawyers Council of Thailand and the competent authority can tell you the current procedure.
Obtain a work permit from the Department of Employment under the Alien Working Act. This is a separate requirement.

Foreign lawyers cannot appear in Thai courts or give Thai-law opinions as licensed Thai lawyers, and many firms state a limit in the engagement letter.

Practising only your home-country law

A foreign legal consultant may advise on foreign and international law, and may work with Thai lawyers in some forms of commercial association. We relied on an older international inventory and law-firm guides, so confirm the current rules.

Understand the legal system first

Thailand belongs to the Civil law family. Knowing how its system works makes the admission route easier to follow.
