Buying and Registering a Car or Motorbike as a Foreigner

The yellow house book is issued by your local district office (amphur or khet) and proves you reside at a specific address. Requirements are a non-immigrant visa with at least six months remaining, your passport, a translated and notarised copy of your passport biographical page, a marriage or rental certification from the property owner, and two Thai witnesses with their ID cards and blue tabien baans. The fee is 20 THB but you should budget half a day and bring three sets of photocopies of everything. In Bangkok, popular amphurs like Watthana and Khlong Toei process the book in two visits over a week. Smaller provincial offices sometimes issue it the same day. Without a yellow book you can still buy a vehicle but must register it in a Thai friend's name, which creates ownership disputes if the relationship sours and complicates resale, insurance claims, and police reports.

New cars from authorised dealers (Toyota, Honda, Isuzu, Mazda, BYD) come with the standard one-year manufacturer warranty, free first-year insurance, and on-the-road pricing that includes registration and number plates. Walk-in negotiations routinely get 20,000-50,000 THB off list plus accessories. New-car finance from Thai banks requires 20-25 percent down, a work permit, three months of payslips, and Thai bank statements; rates run 3.5-5.5 percent flat for three to seven years. Used vehicles cost 30-50 percent less but require a thorough check. Independent inspection services in Bangkok charge 1,500-2,500 THB to verify chassis number, accident history, and outstanding finance. Always insist on seeing the blue book (or yellow if the seller is foreign), check that engine and chassis numbers match the book, and use a DLT-licensed transfer agent (about 1,500 THB) rather than handling the paperwork alone.

Whether new or used, the vehicle must be registered at the DLT office serving the address in your yellow tabien baan. New cars are handled entirely by the dealer's runner — you just sign forms and receive the plates within two weeks. For private used purchases, both seller and buyer attend DLT with the blue/yellow book, sales agreement, both ID documents, and the compulsory CTPL insurance certificate. Transfer fee is 5 percent of the assessed value plus 305 THB administrative. Annual registration renewal (tor ror or) costs 1,000-3,500 THB for cars and 100-500 THB for motorbikes depending on engine size and age, and must be paid every year along with the CTPL renewal. You can pay at any DLT office, at most 7-Eleven stores, or through the DLT app. A 1 percent monthly penalty accrues for late renewals, and after three years lapsed the registration is cancelled and the vehicle cannot be re-registered without a full inspection.

Compulsory Third Party Liability (Por Ror Bor or CTPL) is legally required and costs 645 THB for cars or 365 THB for motorbikes per year. It only pays medical costs to victims, capped at 80,000 THB per person and 300,000 THB if fatal — wholly inadequate for serious accidents. Voluntary insurance comes in classes 1, 2+, 2, 3+, and 3. Class 1 is fully comprehensive covering your own vehicle even in single-vehicle accidents and unidentified third parties, costs 15,000-30,000 THB for an average car, and is what every foreigner should buy. Class 2+ and 3+ are middle-ground options that cover own-vehicle damage only in collisions with identified vehicles, useful for older cars where Class 1 is uneconomic. Class 2 and 3 only cover third-party damage. Major insurers worth using are Dhipaya, Bangkok Insurance, AXA, and Viriyah; avoid cheap unrated providers that fight legitimate claims.
