If you stay here only to get married, you make it yourself difficult. We live here, so if it is longer, not matter that much. If you marry and bye bye Thailand, know that the Thai marriage certificate has to be translated again to the embassy if your husband and eventually yours. Otherwise you be only be legally married for Thai administration. I not understand the use of getting married here, if not staying here. I got my marriage legalised by Belgian embassy, but not Philippine Embassy as more complicated again an not much use.
you need your documents, birth certificate, Cenomar apostled in the Philippines by DFA. Waiting vtime there was 3 months. Then go to Philippine Embassy, waiting time, for appointment, one month. Then papers issued, 2 weeks. Then you need the documents from both embassies translated and approved, the make appointment at townhall. You need a visa of some kind, as you stay here. I had retirement, my wife ed visa.
We went to live here, as getting Schengen visa, was hell, and we love both Thailand. We have a normal relation of 10 years now, so the dessert was not an issue
Write here, or by link of Embassy. Ask your question directly. I would not be surprised if the certificate has to be apostalised in Philippines. I was married to my wife in Thailand. It is registered at Belgian embassy but not bothered to do at Phil 's one. Let us know what they answer. i really hope you not have to get a red ribbon by DFA, took 4 months to have documents, done there.
