Private Loan Agreement for Thailand (English and Thai)
Lending money to a partner, a family member or a friend in Thailand? Thai law requires written evidence signed by the borrower for any loan over 2,000 baht, and limits interest to 15% per year. This pack gives you a professional, plain-language agreement that covers both, and gives the lender clear rules if payments are late.

The law behind this agreement
The agreement and its instructions follow the Thai Civil and Commercial Code. Each link opens the section in our annotated Civil and Commercial Code, with the Thai text, an English translation and Supreme Court decisions.
- Written evidence: a loan of more than 2,000 baht cannot be enforced in court without written evidence signed by the borrower (section 653). The loan is complete when the money is delivered (section 650).
- Interest: not more than 15% per year (section 654), and no interest on overdue interest except in the limited case of section 655. Charging more is an offence under the Excessive Interest Rate Prohibition Act B.E. 2560 (2017). The Supreme Court treats an interest term above the legal rate as void and applies the interest already paid to the principal (Decision 2131/2560).
- Late payment: default interest at the rate of section 7 plus 2% per year (section 224). For instalments, only on the principal of the late instalment (section 224/1).
- Proof of repayment: only by a document signed by the lender, or by the return or cancellation of the loan document (section 653, second paragraph; Decision 22631/2555). The payer is entitled to a receipt (section 326).
- Time limits: 10 years for the loan (section 193/30), 5 years for unpaid interest and instalments (section 193/33).
- Spouses: lending marital money needs the consent of the spouse (section 1476). A debt ratified by the other spouse is a joint debt (section 1490; Decision 7631/2552).
