I am a British retiree living in Bangkok and intend to buy a second hand car. My question is that besides what I have in my passport the necessary visa stamp, I would need a Certificate of Residence for registering me as the new owner at the Lands Department in Mor Chit (if I am not wrong). To get this document from immigration is hectic and have to go very early for a queue. When I obtain my Thai driving licence, I went to the British Embassy, paid 3000 Baht and get it. Can I do the same for buying the car? Many thanks.

why not just go to immigration & maybe pay just 500 bht if that

300 baht from immigration, you need contract if you are renting, 2 photos

Yes, the Embassy will provide the letter.  But...

That's not necessarily the case, try going for the last ticket of the day around 3pm, once you're there with a ticket you have to be processed and the staff will all want to go home soon!   The cost when I got one recently was B200 at Chaeng Wattana. 

 

I got mine after I'd finished getting a new extension after 4pm, the application took 10 mins.

to slightly hijack the thread; is a Stat Dec for a Bkk address from an Embassy accepted by the DLT in Bkk?
