Agree with Robert Dodd; Thai Post is crap; anything in English is just tossed. Mark Russell - a Cert of Life is a requirement of the British State Pension people to prove you're not drawing a pension after you're dead.
Any one who gets out of a Thai Bank in under an hour is a very lucky person. I waited 45 minutes in a Bangkok Bank and watched in horror as TWO counters managed to serve ONE customer. As there were 8 customers in front of me, and aged 82, I decided I had more chance of dying of OLD Age than getting served. Bank assistants cannot stay on task for more than two minutes before they get up for a walk or chat or coffee.
As I explained in my 1st post, I want to go to Spain. I have downloaded the Application form (& will fill it in on my GF's behalf.) I have lots of docs which should ensure a successful conclusion. I don't know the next step after completing the form & gathering the documentation.
