Having a 30 year lease on a land, I want to obtain a building permit.
I read, that the building permit must issued in the name of the registered owner as on the title deed (chanote).
On the other hand, the law said,
a foreigner can own a structure (for example a house),
so it should work, that a foreigner could also get a building permit in his own name.

So far, I read, that having a 30 year lease right, is not enough, for obtaining the building permit in my own name,
I would need some paperwork, that grants me building rights in my own name,
otherwise I will get problems with the city hall/hua yai.

While the thai land owner is living in europe, I have to prepare all required paperwork, befor I fly to thailand, and start with the building permit.

So my question, what paperwork should the landowner sign,
just the simple sentence,
I, xxx, give Mr. yyy the right, to build a house on my land, in his own name ?
