Application for Vehicle Registration, Form 10 T.-9-T (DLT)

Form ขส.บ. 10 ท.-9-ท “แบบคำขอจดทะเบียนรถ” is an application to the Registrar of Thailand’s Department of Land Transport (DLT) to register a vehicle under the Motor Vehicle Act. It is filed for a new or imported vehicle, and when a registered vehicle changes its type or characteristics (for example a converted pickup).

New cars are usually registered by the dealer; the form is useful when you register yourself or through a representative. The form is in Thai: the applicant fills in only the top of page 1; the rest is for DLT officers (checks, plate number, tax, inspection).

• the vehicle owner (buyer or hirer);
• a representative with a power of attorney — often the dealer;
• a company — with its registration documents.

• date (Buddhist Era year, พ.ศ.);
• name, age, nationality, address and phone of the applicant;
• registration type: new vehicle or change of type (then the plate number);
• vehicle make, chassis number, engine make and number;
• the type the vehicle is registered as (RY.1, RY.3, RY.12, etc.);
• ticks for the attached documents.

• the dealer’s or importer’s sale notification;
• the payment receipt;
• the hire-purchase agreement if the car is on hire purchase;
• ID card (a foreigner — passport and residence certificate);
• a power of attorney if a representative files;
• for a company — its registration certificate.

An imported vehicle also needs customs documents. The exact list, tax and fees are not on the form — check with the DLT office.

1. Open the chat, write which vehicle you are registering and send the data from the dealer’s documents.
2. The assistant fills the boxes in Latin letters and ticks the registration type and attachments.
3. Check the fields and download the PDF.
4. Print, sign and file it at the DLT with the vehicle for inspection and the documents.
