If the registration book names your partner, your friend or your employee, then as far as the Department of Land Transport is concerned, that person owns the vehicle. You paid for it, you keep it, you insure it, you ride it every day — and none of those facts appear anywhere in the register. This is an extremely common arrangement among foreigners in Thailand, it is usually entered into for practical rather than devious reasons, and it goes wrong often enough to be worth setting out plainly.

The starting point is that in most cases it is unnecessary. Thai law places no nationality restriction on registering a vehicle, and the Motor Vehicle Act expressly contemplates an applicant who has no domicile in the Kingdom. The reason people use someone else's name is almost always that their address documents were thin on the day — which is a fixable problem, not a permanent one.

You probably did not need a nominee

Section 10 of the Motor Vehicle Act B.E. 2522 opens with "any person" and contains no nationality restriction. Paragraph 2 deals directly with the foreign applicant: where the applicant is an alien and has no domicile in the Kingdom, the application is filed with the registrar of the locality in which they have a place of residence. The requirement is an address, not citizenship, permanent residency or a work permit. See can a foreigner own a car or motorbike in Thailand.

Why people do it anyway

Four reasons account for nearly all of it, and none of them are dishonest:

The first is temporary and worth waiting out. The second is a dealer optimising for a sale this week. The third is a real constraint — car finance for foreigners in Thailand explains why lending is hard — but it means the finance company owns the vehicle anyway and the nominee owns whatever equity there is. The fourth is the one that quietly causes the most trouble, because nobody made a decision at all.

What the registration book actually says about ownership

The book carries two separate roles: the title holder (ผู้ถือกรรมสิทธิ์), who owns the vehicle, and the possessor (ผู้ครอบครอง), who keeps and uses it. The distinction is deliberate — the explanatory note to the 1982 amendment of the Motor Vehicle Act records that the owner and the possessor are not always the same person as the problem the amendment was fixing.

If someone else's name is in both fields, you are neither. You have no recorded interest in the vehicle at all. Every document that will ever be produced about it — the book, the tax record, the insurance policy, the transfer form — points at them. The Thai logbook explained covers what each field records.

What goes wrong, specifically

EventWhat happens
The relationship endsThey own the vehicle. Recovering it means proving, in a Thai court, that the registered owner is not the beneficial owner — expensive, slow, and far from certain
They sell itThey can. They are the registered owner, they hold the book, and a buyer who checks the paperwork finds nothing wrong
They dieThe vehicle forms part of their estate and passes to their heirs, who may have no idea it was ever yours
They fall into debtAn asset registered in their name is an asset creditors can look at
You want to sellOnly they can sign the transfer, and both parties are on a fifteen-day clock once it happens. If they are unavailable, unwilling or abroad, the sale stops
You want to move provinceSame problem — the registered owner has to deal with it
You are in an accidentThe claim runs through the registered owner and the policy in their name; you are a driver, not an insured owner
A fine or unpaid tax attachesIt follows the registered keeper, not the person who was driving
They report it stolenThe register supports their account, not yours

The insurance line is the one that surprises people mid-crisis. Compulsory Por Ror Bor cover attaches to the vehicle and pays for injury to people regardless — see Por Ror Bor explained. A voluntary policy is a contract with a named policyholder, and the settlement conversation involves them, not you. See also crashing a bike you own or borrowed in Thailand.

A private agreement does not beat the register. People commonly sign something between themselves — a loan agreement, an acknowledgement, a bill of sale — and feel protected. Such documents may have value as evidence, and a Thai lawyer can advise on what weight yours would carry. But the land transport office does not read them, an insurer does not read them, and a buyer does not read them. The counter acts on the book.

If you are considering it now

Do not. Fix the address problem instead, because that is the actual obstacle and it is solvable: a certificate of residence from Immigration or your embassy is the ordinary route, and a yellow house book is the stronger one if you are staying. Documents you need to register a vehicle in your name covers how to get each. If you need transport in the meantime, monthly motorbike rental or monthly car rental bridges the gap without transferring an asset to anybody.

If the vehicle would be financed and the lender will only deal with a Thai national, understand what you are agreeing to: the finance company is the title holder until the agreement is settled, and your nominee is the possessor. You are third in a queue of two. Long-term leasing gives you the same car without any of that.

If it is already done

You have three realistic options, in descending order of usefulness.

  1. Transfer it into your name. This is a normal ownership transfer at a land transport office, with the vehicle present and both parties attending or a power of attorney executed. It costs approximately ฿1,000–3,000 all-in for a car and much less for a bike, and it ends the problem. Transferring vehicle ownership at the DLT covers the visit. Do it while relations are good; that is the entire point.
  2. Be recorded as possessor. If a full transfer is genuinely not possible, having your name in the possessor field is better than having no recorded interest at all. It is not ownership and it is not a substitute — but it is a fact on the register rather than a fact in a drawer.
  3. Document everything and take advice. Keep the purchase receipt, the bank transfer, the insurance payments, the tax renewals and the servicing records, all in your name where possible. Then talk to a Thai lawyer about what your position actually is, before you need to know rather than after.

Ask one question: if this person and I stopped speaking tomorrow, what would I have? If the answer is "a receipt and an argument", that is the size of the risk. It may still be a risk you decide to run — plenty of people do, and most of the time nothing happens. Run it knowingly.

The mirror problem

Be equally careful about the reverse. If a friend, a partner or an employer asks to put a vehicle in your name, you are taking on the registered keeper's exposure: unpaid annual road tax, which accrues a surcharge of 1% per month and leads to the registration being suspended after three consecutive unpaid years; the fifteen-day notification obligations when it is transferred or moved; and whatever attaches to a vehicle you cannot see and do not control. If you agree, keep the book yourself and keep the tax paid — and read what happens if you abandon a vehicle in Thailand to see where the obligation ends up if the other person walks away.

Frequently asked questions

Can I put a car in my Thai wife's or girlfriend's name and still own it?

You can put it in their name. You will not own it — the registered owner is the legal owner. Private agreements between you may have evidential value, and a Thai lawyer can advise on that, but they do not change what the register says or what the land transport office will act on.

Do foreigners have to use a Thai nominee for a vehicle?

No. Unlike land, vehicle registration carries no nationality restriction, and section 10 of the Motor Vehicle Act expressly deals with a foreign applicant who has no domicile in Thailand. The practical requirement is proof of a place of residence.

What if the registered owner refuses to sign the transfer?

Then the transfer does not happen, and your remedy is a civil one requiring Thai legal advice and, realistically, a court. This is the situation the arrangement creates and the reason to unwind it early.

Does insurance still pay out if the owner in the book is not me?

Compulsory Por Ror Bor cover attaches to the vehicle and pays for injury to people regardless of who is driving. A voluntary policy is a contract with a named policyholder, and a mismatch between the policyholder, the registered owner and the driver is an argument you do not want to be having after a crash.

Is it different for a motorbike?

No. The book is green rather than blue and the sums are smaller, but the legal position is identical: whoever is named is the owner.
