Understanding the Burden of Proof in Thai Civil Litigation: A Guide by a Bangkok Law Firm

Introduction: Understanding the Burden of Proof in Thailand’s Civil Litigation System

The burden of proof in Thailand is a fundamental legal concept that governs how facts must be established in civil litigation. It defines which party must prove the allegations they bring before a court and significantly affects the outcome of disputes.

For anyone engaged in Thai civil litigation, whether clients or practitioners, understanding this principle is vital. As a lead law firm in Bangkok, we emphasize the importance of grasping the nuances of burden of proof to effectively navigate Thai courts and secure favorable results.

This comprehensive guide explains the burden of proof in Thailand, highlighting statutory provisions, practical examples, and strategic considerations specific to the Thai legal context.

What Is the Burden of Proof in Thailand?

Legal Definition and Practical Meaning

In Thai civil law, the burden of proof (หน้าที่ในการพิสูจน์) refers to the obligation of a party who makes a claim or allegation to substantiate it with evidence. Without satisfying this burden, the party risks losing the dispute on that point.

The guiding legal principle is:

“ผู้กล่าวอ้างต้องเป็นผู้พิสูจน์”
(“He who asserts must prove.”)

This principle is aligned with international civil procedural norms and is embedded in Thailand’s Civil Procedure Code.

Distinction Between Burden and Standard of Proof

While the burden of proof determines who must prove, the standard of proof determines how convincingly the fact must be established. In Thai civil cases, this standard is generally the “preponderance of evidence” (ความน่าจะเป็นมากกว่า) – meaning the fact is more likely true than false.

Thai Legal Framework on Burden of Proof

Statutory Basis: Civil Procedure Code

The burden of proof in Thailand is governed primarily by the Civil Procedure Code, particularly Section 84/1, which states:

“The party who makes an allegation must prove it. If the party fails to prove the allegation, the court may refuse to accept it and may decide against that party.”

This codification is crucial for litigants in determining their evidentiary responsibilities.

Relevant Judicial Interpretations

Thai courts consistently uphold this principle and emphasize the importance of clear and convincing evidence. In some cases, the burden of proof may shift when a party introduces new facts or defenses, but the initial onus always lies with the claimant.

Practical Examples of Burden of Proof in Thailand

Example 1: Debt Claim Case

• Plaintiff’s Position: The plaintiff claims the defendant owes a loan amount.

• Defendant’s Position: The defendant denies the loan agreement.

Here, the burden of proof in Thailand lies on the plaintiff, who must present documentation such as promissory notes or witness testimony to establish the loan’s existence.

Example 2: Illegal Interest Rate Defense

• Defendant’s Position: The defendant alleges that the plaintiff demanded interest rates exceeding legal limits.

In this case, the burden shifts to the defendant, who must prove that the interest rate charged violates Thai law.

2. Insufficient Evidence Submission: Even if the opposing party fails to prove, lacking one’s own proof can cause defeat.
