Firm annotation
Section 6 is part of Book 1 (General Principles) of the Thai Civil and Commercial Code. This entry is awaiting firm-authored commentary; the statutory text above is verbatim from the Office of the Council of State (OCS Krisdika) Thai source, with the English translation from the FAO/UN FAOLEX repository. Always rely on the Thai original for legal proceedings.
Why this matters in practice
For lawyers: when your client's good faith is in dispute, invoke section 6 as a shield — your opponent must affirmatively prove bad faith. This is critical in property and commercial disputes where the bona fide purchaser or transferee defence turns on who bears the proof burden. For laypeople: the law starts from the assumption that you acted honestly; anyone who says otherwise must prove it.
Legislative history
Part of the original Civil & Commercial Code codification; no major subsequent amendment.
Supreme Court decisions interpreting this section
-
Supreme Court Judgment No. 6454/2558 (2015)
The party asserting bad faith bears the full burden of rebutting the statutory presumption of good faith in section 6.
The defendant who had received a transfer of land resisted the plaintiff's claim that the transfer was fraudulent. The Court held that, because every person is presumed to act in good faith under section 6, it was the plaintiff who bore the burden of proving the defendant's bad faith — the defendant merely relied on the statutory presumption without needing to prove innocence affirmatively.
-
Supreme Court Judgment No. 6744/2539 (1996)
A co-owner named on title is presumed by section 6 to hold that interest in good faith; the opposing party must adduce sufficient evidence to displace the presumption.
The plaintiff's name appeared on the title deed as co-owner. The Court held that the plaintiff benefited from the presumption of good faith under section 6 and was presumed to hold co-ownership honestly. The defendant's evidence failed to rebut that presumption.
