Buying Property in Thailand: Legal Checklist.

The short version: six legal stages, one checklist

Buying property in Thailand follows a fairly predictable legal path: reservation, due diligence, contract review, deposit and payment, then registration of the transfer at the Land Office. The risk is not the path itself. It is that Thailand has no mandatory escrow for most private sales, no title insurance market to speak of, and contracts that are often drafted by the seller's side.

That puts the legal checking on you, or on the property purchase lawyers you hire to do it. This guide walks through each stage, what to verify, and where buyers most often lose money. If your first question is whether you can own the property at all as a foreigner, start with the broader guide on whether foreigners can buy property in Thailand, then come back here for the transaction itself.

Step 1: Confirm what you can legally own

Before you reserve anything, be clear on the ownership structure, because it shapes everything that follows.

• Land. Foreigners generally cannot own land under Thailand's Land Code. A house can be owned separately from the land it sits on, but the land itself needs a different arrangement.
• Condominium units. Foreigners can own condos outright, as long as foreign ownership in the building stays within 49% of the saleable floor area under the Condominium Act. The purchase money must usually be remitted into Thailand in foreign currency, with bank evidence (often called an FET form or credit advice) presented at transfer.
• Leases and registered rights. Leases over three years must be registered at the Land Office to be enforceable for the full term, with 30 years as the standard maximum. Usufruct, superficies, and habitation rights are also registered there. The trade-offs are covered in the leasehold vs freehold guide.

One structure to avoid: a Thai company with nominee shareholders set up only to hold land for a foreign buyer. That arrangement is illegal, and it puts the property itself at risk.

Step 2: The reservation agreement and first deposit

Most purchases start with a reservation agreement and a deposit, commonly 50,000 to 200,000 THB for a condo, that takes the property off the market while contracts are prepared.

Read the refund clause before paying anything. A well-drafted reservation agreement states when the deposit is refundable (for example, if due diligence reveals a title problem) and when it is forfeited. Many standard developer and agent forms make the deposit non-refundable from day one, which removes your bargaining power before any checking has happened.

If the seller resists a due-diligence condition entirely, treat that as information.

Step 3: Due diligence, the stage that protects your money

Due diligence: the background checks a buyer runs before committing to the deal. In a Thai property purchase, it usually covers:

• Title search at the Land Office. Confirms the registered owner, the title type, the exact boundaries, and any mortgages, leases, usufructs, or other encumbrances registered against the deed. Title types matter: a Chanote (Nor Sor 4 Jor) is the strongest, while lower-grade documents carry real limits, explained in the title deeds guide.
• Seller verification. Is the person signing actually the owner, or properly authorised by the owner? For company sellers, does the signatory have the power to sell?
• Legal access and land use. Does the land have registered road access? Do zoning and building controls allow what is built, or what you plan to build?
• For condos: the foreign quota balance, the building's debt-free certificate, and unpaid common-area fees, which follow the unit.
• For off-plan purchases: the developer's licence, the land title behind the project, and the construction permits.

A property due diligence review by a lawyer typically wraps all of this into a written report before you sign the main contract. The full scope is covered in the guide to what buyers check in due diligence.

Step 4: Contract review and the main deposit

The sale and purchase agreement is where the deal's real terms live. Before signing and paying the contract deposit (often 5% to 10% of the price, by negotiation), check that the contract states:

• The exact property, by title deed number and unit number, not just an address.
• The full price, the payment schedule, and which bank accounts money moves through.
• Who pays which transfer fees and taxes at the Land Office. Thai law does not fix the split; the contract does.
• The transfer date and what happens if either side misses it.
• Conditions that let you exit with your deposit back, such as a failed title check or, for foreign condo buyers, the foreign quota being full at transfer.
• For off-plan: the completion date, penalties for delay, and the specification the developer must deliver.

Bilingual contracts should state which language version controls. If a dispute reaches a Thai court, the Thai text will usually carry the weight, so it needs to be checked, not assumed to match the English.

Step 5: Payment and the paper trail

Thailand has no general escrow requirement for private property sales, although voluntary escrow services exist under the Escrow Act. Most deals are settled by cashier's cheque handed over at the Land Office on transfer day, which keeps payment and registration simultaneous. Avoid paying the full balance before the day of transfer.

Foreign condo buyers have one extra task: bring the purchase funds into Thailand in foreign currency and keep the bank's remittance evidence. The Land Office will ask for it when registering foreign ownership, and you will want it again if you ever sell and repatriate the proceeds. Your bank issues the document; confirm the current requirements with the bank and the Land Department before transferring.

Step 6: Transfer day at the Land Office

Ownership changes only when the transfer is registered at the Land Office, whatever the contract says. On the day, both sides (or their holders of power of attorney) attend, fees are paid, and the office issues the updated title deed.

The usual costs, calculated on the official appraised value or the sale price depending on the item:

• Transfer fee: 2% (the registration fee under the Land Code; temporary government reductions for qualifying purchases come and go, so check the current rate).
• Stamp duty: 0.5%, or specific business tax of 3.3% instead if the seller has held the property less than five years (with some exemptions).
• Withholding tax: 1% for company sellers; a progressive calculation for individual sellers.

Who actually pays each item is whatever your contract says, which is why Step 4 matters. For worked examples, see the guide to property transfer fees and taxes, and confirm current rates with the Revenue Department or the Land Office before transfer day. Condo buyers can also hand the whole registration step to a condo title transfer service.

Where a local lawyer earns the fee

Property markets in Thailand are local, and so are the practical risks. Bangkok purchases are mostly condos, where the foreign quota, building debts, and developer paperwork are the usual pressure points. Phuket and the islands skew toward villas and leasehold structures, where lease terms, land titles, and building permissions need closer reading.

A lawyer who works that market daily will know which developers deliver late, which title histories deserve suspicion, and what the local Land Office expects. If you are buying in the capital, compare property lawyers in Bangkok. For villa and island purchases, Phuket property lawyers handle exactly these leasehold and land-title questions.

Run the checklist before the money moves

Most Thai property purchases complete without drama. The ones that go wrong usually trace back to a skipped step: a deposit paid on a non-refundable form, a title search nobody ran, or a contract signed in a language the buyer never had checked.

When you are ready, compare property purchase lawyers in Thailand on Justenda, or browse the wider directory of property law firms, message them directly, and get a fixed fee quote for the contract review and transfer before you commit.

A note on what this guide is

This is general information to help you understand how a Thai property purchase works, not legal advice, and rates, quotas, and procedures change. Confirm the current rules with the Land Department, the Revenue Department, or a qualified Thai lawyer before relying on them for a specific purchase.
