Just as Robert and Tod say - I lost mine and on departure asked at check in counter for one and happily given one, no probs at immigration. (This was two months ago)
Used the Consulate for the last 13 yrs. Make sure you have all your paperwork sorted. They are very efficient and helpful. Pay cash. They only issue passports for collection on Thursdays between 1300 &1400( well somewhere round that time) so week to apply and get it granted and pick it up. 10 days to 2 weeks is what you are looking at. You will most prob get a stamp on your visa use before xxx date. So it will become dated from when you enter the Kingdom.
I have done mine there quite a few times and have never been asked for translated docs. My Thai docs in Thai and english supporting docs in english both accepted. My wife even does her support/confirmation letter in thai.
Based on marriage - Perth did not require translated docs but each application is done on a case by case basis with possible additional documentation required. Go to the website of the consulate (as Tod mentioned) and they will have a checklist incuded on the application form. I found Perth very accomodating
My apologies, I am easilly confused! When applying both in and out (perth/trat) these were requested. Apologies for any confusion I may have caused. Please ignore my previuos comment, cheers!
Along with house book, wife ID, updated martiage cert etc as mentioned, I have always had to have funds 400k no less than 2 months old in my bank with a letter from the bank stating as such, photos of my wife and me at home, a mud map how to get to our house.
