Hi Death, I have a yellow book through a house that my wife and I bought in the Pattaya area. As far as I understand the house owner (my wife) can add anyone who lives at the house into the tabien baan. We are not Thai so can not be in the blue book, so hence the need for a yellow book.
I had to get references from 3 Thai people that could vouch for me as being OK. The house builder and his family did this for me. My wife and I went to the Amphur and made the application and 2 months later we got the yellow book. Quite a long process, but got there in the end. Only ever used it as proof of address, so not sure how useful it is.
Cheers, Rick
