Section 806
Statutory text (Thai original)
ตัวการซึ่งมิได้เปิดเผยชื่อจะกลับแสดงตนให้ปรากฏและเข้ารับเอาสัญญาใด ๆ ซึ่งตัวแทนได้ทำไว้แทนตนก็ได้ แต่ถ้าตัวการผู้ใดได้ยอมให้ตัวแทนของตนทำการออกหน้าเป็นตัวการไซร้ ท่านว่าตัวการผู้นั้นหาอาจจะทำให้เสื่อมเสียถึงสิทธิของบุคคลภายนอกอันเขามีต่อตัวแทน และเขาขวนขวายได้มาแต่ก่อนที่รู้ว่าเป็นตัวแทนนั้นได้ไม่
Verbatim from the Royal Gazette / Office of the Council of State
English translation
An undisclosed principal may declare himself and assume any contract entered into on his behalf. But the principal who allows his agent to act as a principal cannot prejudice the rights of the third person against the agent acquired before notice of agency.
