Sor Por Kor land can be inherited, can only be mortgaged through the Agricultural Bank of Thailand and cannot be sold.
This is part of the current governments policy to grant land plots to farmers for agricultural purposes, invariably fruit producing trees. Clearly left hand/right hand departments dont share what is public knowledge. Boundary stone markers, now in dispute, were legally moved by the Agricultural Ministry weeks ago.
That said, it's ripe for corrupt practices.
