No, YOU do not need to take the bike back to your old home province, however, if the new buyer wishes to register the bike, say, in BKK., he will have to. This is where you give him your ' power of attorney ' form. LivinLOS has obviously done his transfers differently to the way we have been told by the licensing office ( our transfers have always been done on the day we went to the relevant licensing office -- we haven't had to wait for two weeks for anything else to be done ). I have had two experiences in transferring vehicles, and both have involved the same proceedure. 1) The Honda I bought in Chantaburi and registered in Pattaya. I went to the Pattaya licewnsing office with the bike. They told me I had to take it back to Chantaburi, ( pay any outstanding back road tax first - great ), then de-register it there, and then bring it back to Pattaya to register it at my Jomtien address. I actually had and used the option to keep the Chantaburi licence plate on the bike as it was pertinent to the age of the bike ( 1966 ) but to even do this I had to pay one of the Chantaburi staff 100 baht ' under the counter ' to use her Chantaburi address to ' guarantee ' an address for the number. This was actually easier than having the Chantaburi plate removed. The bike was then registered in Pattaya. 2). I bought a VW Beetle in Pattaya which was on Yasothon plates but with the book showing a Pattaya address. I subsequently moved to the Buriram area. After visiting the Buriram licensing office, I had to drive the car to Yasothon to de-register it there and advise them of a change of plates and address. We then drove back to the Buriram licensing office where we got new plates and the book address changed to our house in the Buriram province. Another little known fact IS, if you transfer a vehicle/motorbike etc., into a province, you MUST go to the main licensing office within the province to register the vehicle, in this case Buriram. When we wanted to sell the VW and it was going out of province, we could NOT do this in Buriram, but rather in our local office at Prakhon Chai. Again here, we tried to bribe the official in Buriram to save us the hassle, but he told us ' I'll take your money, and then you'll still have to go to the Prakhon Chai office, so save your money ". And, YES, if you are a foreigner, every time you buy or sell a motorised vehicle, you need to get a Resident Permit from your local Immigration Office -- cost, 500 baht every time. I am only telling you how WE had to do our two transfers, but I really don't see how anyone can bypass the system. But, TIT and anything can and often does happen. The misses is quite adamant that any further purchases should be either new, or with our province plates already on. As she has to sort out most of the ' crap ' sorry, paperwork, I don't blame her ( read my report on buying a bike without a green book without knowing the excise duty hadn't been paid )
