Introduction

DNA testing plays a critical role in both civil and criminal legal matters in Thailand. It serves as an essential tool for establishing biological relationships, resolving disputes, and aiding forensic investigations. Understanding the legal framework governing DNA testing under Thai law is crucial for individuals and businesses seeking clarity on its applications and implications. This blog explores the relevant laws, procedures, and legal consequences associated with DNA testing in Thailand.

The Legal Basis for DNA Testing in Thailand

Several statutes and legal provisions regulate DNA testing in Thailand, including:

• Civil Procedure Code (Section 1281): Allows DNA testing to establish paternity or inheritance claims.

• Criminal Procedure Code (Section 244/1): Permits DNA evidence in criminal cases, especially in sexual assault and homicide cases.

• Juvenile and Family Court Act (Section 160): Grants courts the authority to order DNA testing in family disputes.

Courts may order DNA testing if it is deemed necessary to determine a material fact in a case. If a party refuses to undergo testing, the court may infer that the refusal supports the opposing party’s claims.

Applications of DNA Testing in Thai Legal Proceedings

1. Paternity and Child Custody Cases

   • DNA tests help establish a biological relationship between a father and child.

   • The court may order testing when paternity is disputed in child support and custody battles.

2. Inheritance and Succession Disputes

   • DNA testing determines biological lineage in cases where an heir’s legitimacy is questioned.

   • It helps prevent fraudulent claims over estate distribution.

3. Criminal Investigations

   • DNA evidence is widely used in rape, murder, and missing persons cases.

   • Thai law enforcement agencies rely on DNA testing to link suspects to crime scenes.

4. Immigration and Nationality Issues

   • DNA tests can support applications for Thai citizenship where lineage must be proven.

   • They assist in visa and immigration-related matters.

The Procedure for Court-Ordered DNA Testing in Thailand

1. Filing a Motion

   • The requesting party submits a formal request to the court explaining the necessity of DNA testing.

2. Judicial Review

   • The court evaluates the request to determine whether the test is essential for case resolution.

3. Appointment of an Accredited Laboratory

   • Testing must be conducted at a certified institution recognized by Thai authorities.

4. Sample Collection and Analysis

   • Samples are collected under strict protocols to maintain integrity.

   • Results are submitted to the court as admissible evidence.

Consequences of Refusing a Court-Ordered DNA Test

Under Thai law, refusal to comply with a court-ordered DNA test may result in legal presumptions against the refusing party. This is particularly significant in paternity and inheritance disputes, where non-compliance can lead to adverse judgments.
