i didnt use both parents for tabien baan and i didnt say u did. To first register a thai citizen into a home, usually they need the mother to register first into any home. Its way easier as a baby, im assuming OP is not a baby. However, i dont know why you think you're the only one who knows anything. Ive seen you replying to others. That was your experience, that was mine. Dont know of you know but thai embassies and kades dont always require the same thing. OP asked for help, i gave her mt experience. She did not provide full info on her post and i did not feel the need to read other comments or responses. I replied to what was written, but your first response made me want to read others and i saw many that were similar to mine. I didnt think your comment matched her but im not the OP, so maybe it did. So, i minded my own business, offered what happened to me, and let OP decide. Which you should as well. Not everyone has the exact same experience.
Also while reading through some, seems the problem is thai mom doesnt have some thai papers needed to do this which makes my response and some of yours useless as mom needs to get her docs first. OP original post isnt clear. I cant help with her mom docs since i dont have experience with that and if she clarified that we wouldnt have this convo. Responses like yours seem like an attack on someone whos just trying to help, my response is better than those negative comments.
Hi! I did this but from america which should be the same. You first have to file for Thai birth certificate. The thai embassy tells you what documents you need from both your parents. I had to lcall into the Thai embassy in LA, which answered my call yesterday about another question, so if you want call that one. However, you local one may ask for something slightly different. Also, they give you forms to fill out. There are more work if your parents were not married and you use your dads last name. He must write a letter saying he allows you to use his last name.
-thai birth certificate form
-your birth certificate
-parents ID
-thai parents thai ID, i forget if passport is ok
-your ID
Then when you get this, you can apply for thai passport. Then when in Thailand, you can apply for Thai ID which requires your thai parent to register you into a house (tabien baan). Thai parent has to be present. If already passed, they accept dealth certificate. Or 2 siblings can come and verify. This was the hardest part for me. But you dont need Thai ID if you dont plan on working or buying house here. If you just want the passport, you dont need this.
