Vehicle Registration Book
A vehicle registration book is issued by the registrar under the Motor Vehicle Act B.E. 2522 and records the vehicle details, chassis and engine numbers, and the name of the owner or possessor. It supports sales, export formalities and proof of assets abroad.
The registration book is a registration record rather than an absolute title deed. It can name the owner and the possessor separately — for example, a finance company holds ownership during a hire-purchase term. That distinction matters abroad, because the reader is deciding who may dispose of the vehicle.
Recipients scrutinise the chassis number, engine number, make and model, year of registration and transfer history. The translation must reproduce every character exactly. One wrong digit in a chassis number gets the file returned, and in an export matter it can disrupt the entire customs formality.
The book has several sections: vehicle particulars, annual tax records and transfer entries. Agree with the receiving authority in advance whether the whole book or specific pages are needed, so the translation and certification scope is exactly right.
If the original is held by a finance company during a hire-purchase term, obtain a certified copy from the holder or proceed through the registrar by the channel the law provides before starting translation and legalisation.
Documents to prepare
- The original registration book, or a copy certified by the registrar or the holder
- The owner's or possessor's ID card or passport
- A company affidavit letter where the vehicle is registered to a company
- A power of attorney where an agent acts for the owner
- A translation of the relevant pages, signed by the translator who takes responsibility
Step order
- Confirm with the recipient whether the whole book or only the particulars and transfer pages are needed
- Obtain the original, or a copy certified by the holder or the registrar
- Translate the relevant pages, reproducing chassis and engine numbers character for character
- Add Notarial Services Attorney certification where the destination requires notarised form
- File for legalisation at the Department of Consular Affairs as the destination requires
- Legalise at the destination country's embassy or consulate, or obtain an apostille once the Convention is in force for Thailand
Pre-filing checklist
- Chassis and engine numbers in the translation match the original exactly
- Owner and possessor are clearly distinguished in the translation
- Every page the destination asked for is translated, including transfer entries
- Encumbrances such as hire purchase are stated as they appear in the document
- Any copy filed is certified by a person actually authorised to certify it
Practical tips
- Scan every page before handing the original to anyone; replacement books take time and come with conditions
- If the vehicle is under hire purchase, ask the finance company early whether it will issue consent or a certified copy
- For export matters, use the same translation set filed with customs so the two records cannot conflict
- Check that the company name in the book matches the latest company affidavit letter
Common pitfalls
- One wrong digit in a chassis number, which gets the whole set rejected
- Translating only the first page and omitting the transfer history the recipient needs
- Filing a self-made photocopy with no authorised certification
- Omitting encumbrances, so the paperwork does not match reality
Frequently asked questions
Is the registration book proof of ownership?
It is a registration record naming the owner and possessor as entered by the registrar, not a title deed. Proving ownership usually also requires the sale or hire-purchase contract.
Must the whole book be translated?
Not always — follow the destination's instruction. Most want the particulars page and the transfer entries. Absent a clear instruction, translating every page bearing text is the safer choice.
The car is still on finance. Can I still file the book abroad?
Documentarily yes, but the reader will see the finance company as owner, so a consent letter or confirmation from the owner is usually needed as well.
The book is lost. What now?
Apply to the Department of Land Transport registrar for a replacement under the applicable rules, then send the replacement through translation and legalisation.
What extra documents does exporting a vehicle need?
Beyond the book, customs formalities under the Customs Act B.E. 2560 apply, plus whatever the destination requires for vehicle import. Check both sides before translation begins.
Does the translation need embassy legalisation?
It depends on the destination. For sale or foreign registration it usually needs Department of Consular Affairs legalisation and embassy certification, replaced by an apostille once the Convention is in force for Thailand and the destination is a party.
