Thailand is a civil law country meaning that its basic laws are to be found in written codes, similar to those found in continental Europe. This is unlike the common law system that prevails in the USA, the United Kingdom and most of the Commonwealth.

There are four basic codes in Thai law:
• the Civil and Commercial Code
• the Civil Procedure Code
• the Criminal Code
• the Criminal Procedure Code

There are also specific codes that deal with specific areas of law, for example:
the Land Code and the Revenue Code.

In addition there are also Acts of Parliament, decrees, ministerial regulations and notifications.

Although the Thai law is similar to those found in many countries in the world, there are numerous differences. These similarities and differences extend to the legalities of land and structures (houses / villas, townhouses, apartments etc.).
