The house registration book is only issued to the owner of the property.
I was registered on my mom’s book while I was away in the states and remained on that book when I returned even though I didn’t leave there.
I then registered on my niece’s book until I bought a condo couple years later after my mom passed away and we sold her home.
I am sure your wife have family members that own property who wouldn’t mind adding
her to their book as all Thai’s are required to be registered on the book then she will do a change of address on her ID with that address. Again, here in Thailand address on the ID is where you are registered on the house book and not always be the actual address where you live. It does not make sense but just how it works here.
It’s a pain in the neck system. I had to go through this to reinstate my Thai citizenship and not having to dealing retirement visa ever again once I decided to live here permanently.
I hope y’all will find a solution for this. Good luck to y’all.
