Section 454
Statutory text (Thai original)
การที่คู่กรณีฝ่ายหนึ่งให้คำมั่นไว้ก่อนว่าจะซื้อหรือขายนั้น จะมีผลเป็นการซื้อขายต่อเมื่ออีกฝ่ายหนึ่งได้บอกกล่าวความจำนงว่าจะทำการซื้อขายนั้นให้สำเร็จตลอดไป และคำบอกกล่าวเช่นนั้นได้ไปถึงบุคคลผู้ให้คำมั่นแล้วถ้าในคำมั่นมิได้กำหนดเวลาไว้เพื่อการบอกกล่าวเช่นนั้นไซร้ ท่านว่าบุคคลผู้ให้คำมั่นจะกำหนดเวลาพอสมควร และบอกกล่าวไปยังคู่กรณีอีกฝ่ายหนึ่งให้ตอบมาเป็นแน่นอนภายในเวลากำหนดนั้นก็ได้ ว่าจะทำการซื้อขายให้สำเร็จตลอดไปหรือไม่ ถ้าและไม่ตอบเป็นแน่นอนภายในกำหนดเวลานั้นไซร้ คำมั่นซึ่งได้ให้ไว้ก่อนนั้นก็เป็นอันไร้ผล
Verbatim from the Royal Gazette / Office of the Council of State
English translation
A previous promise of sale made by one party has the effect of a sale only when the other party has given notice of his intention to complete the sale and such notice has reached the person who made the promise. If no time has been fixed in the promise for such notification, the person who made the promise may fix a reasonable time and notify the other party to give a definite answer within that time whether he will complete the sale or not. If within that time he does not give a definite answer, the previous promise loses its effect.
