ทรัพย์ซึ่งติดกับที่ดินหรือติดกับโรงเรือนเพียงชั่วคราวไม่ถือว่าเป็นส่วนควบกับที่ดินหรือโรงเรือนนั้น ความข้อนี้ให้ใช้บังคับแก่โรงเรือนหรือสิ่งปลูกสร้างอย่างอื่น ซึ่งผู้มีสิทธิในที่ดินของผู้อื่นใช้สิทธินั้นปลูกสร้างไว้ในที่ดินนั้นด้วย
Verbatim from the Royal Gazette / Office of the Council of State
English translation
Things temporarily fixed to land or to a building do not become component parts of the land or building. The same rule applies to a building or other structure which, in thee exercise of a right over another person's land, has been fixed to the land by the person who has such right.

Firm annotation
Section 146 matters in three recurring situations: (1) a foreigner who builds a house on Thai-spouse-owned land — the house follows the land into the spouse's name unless a §1410 superficies is registered separately; (2) a mortgage of land — fixtures pass to the mortgagee on foreclosure; (3) a tenant's improvements — usually become the landlord's property unless removable under §1394.
