Legal Framework

Independence of Justice
When under civilian rule, judiciary is generally regarded as independent though it is subject to corruption and heavy backlog of cases.
Equal Treatment of Nationals and Foreigners
Foreign nationals can normally expect impartial trial from the country’s judicial system.
The Language of Justice
Thai is the judicial language used in Thailand, though English is widely used.
Recourse to an Interpreter
It is possible to have access to a transleter.
Sources of the Law and Legal Similarities
The main source of law in the country is the new constitution of October 1997. The legal system is based on civil law system. Thailand has not accepted compulsory ICJ jurisdiction. Thailand's legal system blends principles of traditional Thai and Western laws. Under the constitution, the Constitutional Court is the highest court of appeals, though its jurisdiction is limited to clearly defined constitutional issues. Its members are nominated by a committee of judges, leaders in Parliament, and senior independent officials, whose nominees are confirmed by the Senate and appointed by the King. The Courts of Justice have jurisdiction over criminal and civil cases and are organized in three tiers: Courts of First Instance, the Court of Appeals, and the Supreme Court of Justice. Administrative courts have jurisdiction over suits between private parties and the government, and cases in which one government entity is suing another. In Thailand's southern border provinces, where Muslims constitute the majority of the population, Provincial Islamic Committees have limited jurisdiction over probate, family, marriage, and divorce cases. Only Thai-qualified lawyers have rights of audience in the country’s courts so many domestic firms focus on litigation, although international firms often retain significant Thai expertise. The country recently introduced specialised courts for bankruptcy and IP cases.
