There are two types of land titles in Thailand over which registerable right of ownership can exist. These are Chanote and Nor Sor Sam Kor. They are the only types of land title that a careful foreign investor should consider. Chanote (Chanote ti din) Chanote titles are issued by the Thai Land Department and are accurately surveyed and plotted in relation to the national survey grid. They are also marked by unique numbered posts set in the ground. The ownership of the land title can be transferred within a matter of hours. This is the best type of land title for a foreign investor. Nor Sor Sam Kor These titles, though still measured relatively accurately, are less accurately measured than Chanote titles. Transfer of ownership can take longer than the case of Chanote. Nor Sor Sam The predecessor to Nor Sor Sam Kor was Nor Sor Sam. The boundaries of Nor Sor Sam titles are only recorded with relation to neighboring plots and survey errors of up to 20% are not unusual. Unlike Nor Sor Sam Kor, Nor Sor Sam titles also require 30 days public notice before any change of land ownership can occur. There are many types of land title less recognised than Nor Sor Sam such as Sor Kor Nung. These are basically and form of squatters or settlers claim. You cannot even apply for or obtain approval to build on such land.
