I want to continue sharing this moment with you because, as I wrote previously, you are a truly useful source of information. I want to thank everyone who suggested a company that could follow my path until the ashes were repatriated and I must thank Mr. Cody Hambly, Senior Case Manager, for his help. I don't know if I can put the name of the company, so I won't do it for the moment.
I also contacted the Embassy, but luckily Mr. Hambly has someone who can help me with this too.
The bank account is not a problem, as my wife received her money in a Spanish account and did not have any here in Thailand. I just don't understand, but maybe I'm wrong, why the tourist police were called to the morgue and not the "normal" one. But it doesn't matter.
I am now in Bangkok waiting for the necessary documents to be translated, having married abroad.
