I really don't get this thread.
My Thai wife has a bkbk a/c with ATM card and blue book.
I have the same.
We also have a joint a/c with the same bank.
The yellow house book, which does not expire, is accepted as a form of identification with your legal name and address printed inside. So, once you have this book (and accompanying ID card), you don't need to get any other affidavits or certificates of residence to prove your address in Thailand.
