I have attached the Thai version of the Thai condo act.
I am not sure if it is formatted the same way as the English version that I have.
I want you to look and see if you can find the same section #18 as in the English version that outlines the fees and payments due for such things as CAM fees and interest charges at 12% and 20%.
It should be similar to the section I have copied below.
Let me know if you can find it here first then I will show you what we need to do with it.
