, if it really needs to be translated is a good question when the original is in English. But if not translated then he will need his passport translated into Thai and legalized by the Australian Embassy and then MFA Thailand.
, he will need to get the translation legalized in Australia. I dont think the Australian Embassy will legalize it without being legalized by the MFA in Australia, but he can try ask.
It is kind of funny that ppl are amazed when European countries are capable of issuing a new passport in 14 days. In Thailand my two sons got a new passport applied for on Friday and received by EMS on Tuesday. It was not even express service.
, he IS married already to a Thai national. He needs the marriage certificate translated and legalized. It first needs to be legalized in Australia at the MFA. Then it needs to be legalized by the Australian Embassy in Thailand. And finally legalized at the MFA in Thailand.
, didnt you just said that you didnt ask for any "special" services? Of course, you can use an agent to prepare your documents without being stuck with this agent. How much did you pay for such a service?
