Section 643
Statutory text (Thai original)
ทรัพย์สินซึ่งยืมนั้น ถ้าผู้ยืมเอาไปใช้การอย่างอื่นนอกจากการอันเป็นปกติแก่ทรัพย์สินนั้น หรือนอกจากการอันปรากฏในสัญญาก็ดี เอาไปให้บุคคลภายนอกใช้สอยก็ดี เอาไปไว้นานกว่าที่ควรจะเอาไว้ก็ดี ท่านว่าผู้ยืมจะต้องรับผิดในเหตุทรัพย์สินนั้นสูญหายหรือบุบสลายไปอย่างหนึ่งอย่างใด แม้ถึงจะเป็นเพราะเหตุสุดวิสัย เว้นแต่จะพิสูจน์ได้ว่าถึงอย่างไร ๆ ทรัพย์สินนั้นก็คงจะต้องสูญหายหรือบุบสลายอยู่นั่นเอง
Verbatim from the Royal Gazette / Office of the Council of State
English translation
If the borrower uses the property lent for purposes other than ordinary purposes or purposes appearing from the contract, or lets a third person have the use of it, or keeps it longer than ought to, he is liable for any loss or damage to the property caused by force majeure unless he proves that the loss or damage would have happened in any case.
