Jurisdiction overview

Thailand is the only country in South East Asia that was never colonised, so Thai law has naturally taken on its own identity. Yet this hasn’t made its legal system simpler as it’s largely formed of a mixture of German, Swiss, French, English, Japanese, Italian, and Indian laws and practices. Even today, Islamic laws and practices exist in four southern provinces.

In Thailand there are some restrictions on foreign law firms practising in the country, but the legal sector is generally open to international law firms when compared to other jurisdictions in the region. The likes of Baker & McKenzie, Allen & Overy and Linklaters all have a presence in the country. 

Under the Foreign Business Act, foreign law firms are only allowed to establish joint ventures with a local partner and must register as limited companies. This restricts ownership of the foreign firm in Thailand of up to 49% against Thai ownership of at least 51%. Only lawyers admitted in Thailand holding Thai nationality can give advice, consult Thai laws and appear before the courts. 

Thailand’s real estate, leisure, manufacturing, technology and telecoms industries remain strong as a result of active inbound investment from China and Japan. Myanmar is a key focus for Thai outbound investment.
