HomeThailand and Malaysia maintain formal extradition arrangements that facilitate the transfer of individuals accused or convicted of crimes between the two neighboring countries. The extradition relationship between these nations has a Yes status, with its legal foundation tracing back to a treaty signed in 1911 that was later applied to Malaysian territories through a 1992 order. This longstanding cooperation reflects the shared commitment of both countries to combat cross-border crime and ensure that justice can be pursued regardless of national boundaries.
The legal framework governing extradition between Thailand and Malaysia is primarily established through Thailand’s Extradition Act and Malaysia’s corresponding extradition legislation. These domestic laws work in conjunction with the bilateral treaty to define the specific procedures, requirements, and limitations that govern how extradition requests are processed and executed. The legislation of both countries ensures that the extradition process follows established legal protocols while respecting the rights of individuals subject to such proceedings.
The current system operates under the historical UK-Siam 1911 treaty as applied to Malaysian states, with extradition requests processed through Thailand’s Central Authority at the Office of the Attorney General. Key principles include double criminality requirements with minimum one-year penalties, political offense exceptions, and general protection for Thai nationals unless specific treaty provisions or government consent apply.
Does Thailand Have an Extradition Treaty with Malaysia?
Treaty: Yes
Signed: 1911
Status: Applied via 1992 order
Thailand maintains extradition arrangements with Malaysia based on the historical UK–Siam treaty of 1911, which was applied to the Malay states. Malaysia’s 1992 order formally recognizes the application of this treaty framework to modern extradition relations between the two countries.
Extradition requests between Thailand and Malaysia are processed through Thailand’s Central Authority, which is the Office of the Attorney General. The extradition process operates under several key principles including double criminality requirements (with a minimum penalty threshold of one year), the rule of speciality, and political offence exceptions.
Thai nationals are generally not subject to extradition unless specifically permitted by treaty provisions or with explicit consent and Cabinet approval. In cases where no specific treaty provisions apply, extradition may still be possible on the basis of reciprocity under Thailand’s Extradition Act B.E. 2551 (2008).
The proximity and shared history between Thailand and Malaysia, along with their ongoing cooperation in regional security matters, generally facilitate the extradition process between these neighboring Southeast Asian nations, though each case is evaluated according to the established legal framework and bilateral agreements.

The extradition relationship between Thailand and Malaysia operates under the historic UK-Siam Treaty of 1911, which was extended to the Malay states, with Malaysia’s Extradition Order (1992) formally recognizing its continued application. Key legal principles include double criminality (minimum one-year penalty), the rule of specialty, and political offense exceptions, while Thai nationals are generally not extradited unless the treaty specifically permits or with Cabinet approval and consent.
Grounds for Refusal
Thai law recognizes several circumstances under which extradition requests may be denied, even when a valid treaty exists between Thailand and Malaysia. The most fundamental protection involves political offences, where individuals cannot be extradited if their alleged crimes are considered political in nature rather than ordinary criminal acts. This principle reflects the longstanding international legal tradition that extradition should not be used as a tool for political persecution.
The issue of dual citizenship presents another significant ground for refusal, particularly relevant given the historical connections between Thailand and Malaysia. When a person holds Thai nationality alongside Malaysian citizenship, Thai authorities may refuse extradition based on the principle that states generally protect their own nationals from being surrendered to foreign jurisdictions. This protection becomes especially important when the individual’s primary ties and residence are in Thailand.
International human rights considerations play a crucial role in extradition decisions, with risk of death penalty or torture serving as compelling grounds for refusal. Thai courts and authorities must evaluate whether the requesting state can provide adequate assurances that the individual will not face capital punishment or cruel treatment, as these protections are enshrined in various international agreements and Thai constitutional principles.
- Political or military offences – crimes deemed political rather than criminal in nature
- Risk of persecution – potential for unfair treatment based on race, religion, or political beliefs
- Double jeopardy (ne bis in idem) – prohibition against being tried twice for the same offence
- Time-barred offences – cases where the statute of limitations has expired
- Death penalty without assurances – lack of guarantees against capital punishment
The extradition framework between Thailand and Malaysia operates under the UK-Siam 1911 treaty as applied to Malay states, with Malaysia’s 1992 order recognizing this application. Requests must proceed through Thailand’s Central Authority at the Office of the Attorney General, adhering to requirements including double criminality with minimum one-year penalties, the rule of speciality, and political offence exceptions. Thai nationals are generally not extradited unless the treaty specifically permits or Cabinet approval is obtained, though reciprocity arrangements under the Extradition Act B.E. 2551 (2008) may apply when no treaty exists. Despite these protective limitations, extradition regularly proceeds for conventional criminal matters such as fraud, corruption, drug trafficking, money laundering, cybercrime, and violent crimes, where the legal standards are clearly met and human rights concerns are adequately addressed.
Notable Cases of Extradition from Thailand to Malaysia
In 2025, Thailand processed several high-profile extradition requests from Malaysia, including a case involving a Malaysian national charged with large-scale methamphetamine trafficking across the Thai-Malaysian border.
Another significant case involved the extradition of a suspect in an online investment fraud scheme that defrauded Malaysian investors of over 50 million ringgit through cryptocurrency platforms.
The extradition framework between Thailand and Malaysia operates under the historical UK-Siam 1911 treaty, which was extended to cover the Malay states, with Malaysia’s extradition order from 1992 formally recognising its application. All extradition requests are processed through Thailand’s Central Authority, the Office of the Attorney General, and must satisfy key requirements including double criminality with a minimum penalty of one year imprisonment, adherence to the rule of speciality, and the political offence exception. Thai nationals are generally not extradited unless the treaty specifically permits it or with explicit consent and Cabinet approval. In cases where no treaty exists, extradition may still be possible on a reciprocity basis under Thailand’s Extradition Act B.E. 2551 (2008).
Common grounds for refusing extradition include political or military offences, risk of persecution based on race, religion, nationality, or political opinion, double jeopardy (ne bis in idem) where the person has already been tried for the same offence, cases that are time-barred under applicable statutes of limitations, and requests involving the death penalty without adequate assurances that it will not be imposed or carried out. Extraditable offences typically encompass fraud, corruption, drug trafficking, money laundering, cybercrime, and violent crimes that meet the dual criminality threshold.
Alternatives and Legal Defense
Individuals facing extradition from Thailand to Malaysia have several legal avenues available to challenge the proceedings. These include filing formal appeals through Thailand’s court system, securing experienced legal representation to mount a comprehensive defense, and exploring asylum pathways where applicable. The strength of these options depends on the specific circumstances of each case, the nature of the alleged offenses, and the individual’s personal situation regarding potential persecution or unfair treatment.
| Option | Explanation |
|---|---|
| Appeal | Formal court challenges can be mounted on various grounds including political/military offenses, risk of persecution, double jeopardy (ne bis in idem), time-barred offenses, or concerns about death penalty without proper assurances. Appeals must demonstrate that extradition would violate fundamental legal principles or human rights protections. |
| Defense by lawyer | Experienced legal counsel can challenge extradition requests by examining procedural compliance, questioning evidence validity, and arguing against double criminality requirements. Defense strategies often focus on demonstrating that alleged crimes such as fraud, corruption, drug trafficking, money laundering, cybercrime, or violent crimes do not meet treaty requirements or that extradition would be unjust. |
| Asylum pathways | Individuals may seek protection through asylum applications if they can demonstrate a well-founded fear of persecution based on political opinion, religion, race, nationality, or membership in a particular social group. This option is particularly relevant for those facing politically motivated charges or where return would result in torture, inhuman treatment, or violation of fundamental rights. |
