Property Due Diligence in Phuket: Buyer's Checklist

Property due diligence in Phuket is the set of legal checks an independent lawyer carries out before you sign a contract or pay a deposit: verifying the title deed at the Land Office, searching for mortgages, leases and court seizures, and confirming access, zoning, permits and, for condos, the foreign quota and the building's debt-free letter. It costs far less than fixing a bad purchase, and it is the single best protection a foreign buyer has on the island.

This guide explains what a proper check covers for condos, villas and land, the documents to ask for, the red flags Phuket buyers meet most often and how long the process takes. It is general information, not legal advice.

Why does property due diligence in Phuket matter?

Thailand has no title insurance system of the kind buyers know from some Western countries, so the buyer carries the risk of a defective title, an unregistered lease or a building that was never properly permitted. Phuket adds its own issues: hillside plots with slope and height limits, coastal zoning, older land documents in some areas, and a long history of foreigners holding villas through structures that do not survive scrutiny. Recent enforcement, such as the nominee probe into Rawai companies, shows that authorities do check.

What does the title deed check involve?

Your lawyer obtains a certified copy of the deed from the Land Office that holds it. For Phuket that is the Phuket Provincial Land Office or one of its branch offices, depending on where the plot sits. The check covers:

• Type of title: a Chanote (Nor Sor 4 Jor) is the strongest and fully surveyed title. Weaker documents such as Nor Sor 3 Gor carry more boundary and transfer risk. Our Chanote title in Phuket guide explains the differences.
• Registered owner: the name must match the seller, and anyone signing for a company or another person needs valid authority.
• The registration history on the back of the deed: sales, mortgages, leases, usufructs, servitudes and seizure orders are all recorded there.
• Plot location and size: the Department of Lands' LandsMaps service shows the plot's location, shape and official appraised value, which helps spot a deed that does not match the land you visited.

Some local firms note that, since Thailand's personal data law took effect, Land Offices often release a certified copy only to the owner or someone holding the owner's written authorisation, so ask the seller to sign one at the reservation stage. Official information on land registration is published by the Department of Lands.

What extra checks apply to a condo?

For a condominium unit, the building's juristic person, the owners' body that manages it, is the key source. Ask for:

Document	Why it matters
Foreign quota letter	Foreigners can own units freehold only within 49% of the building's total unit area. See our Phuket condo foreign quota guide.
Debt-free certificate	Section 29 of the Condominium Act says a transfer cannot be registered unless the unit is free of unpaid common charges.
Audited accounts and AGM minutes	Show the sinking fund, owners in arrears and planned repairs or special levies.
Building regulations	May restrict pets, renovations and short-term letting.

Running costs matter too; our guide to Phuket condo common area fees shows what owners typically pay. If you plan to rent the unit out, check the rules on daily letting first, as explained in is Airbnb legal in Phuket.

What about villas and land?

Because foreigners generally cannot own land in their own names, villa deals are usually structured as a registered lease of the land combined with ownership of the house, or a right of superficies. Due diligence should confirm that the structure is lawful and that it will actually be registered:

• Lease registration: under the Civil and Commercial Code a lease of more than three years must be registered at the Land Office to be enforceable for its full term, and the maximum registered term is 30 years. Promises of automatic renewals are contract rights, not guarantees, as our 99 year lease in Thailand article explains.
• Legal access: the plot should touch a public road or have access through a registered servitude, not an informal arrangement with a neighbour.
• Zoning and slope limits: Phuket's town plan and environmental rules can restrict building on hillsides, near the coast and above certain elevations.
• Building permit and completion: the house should match its permit, and larger projects may also need an environmental approval.
• No nominee structure: a Thai company whose Thai shareholders hold shares only on paper for a foreigner is unlawful and can be challenged.

Which red flags should stop a deal?

• The seller pushes for a large deposit before your lawyer has seen the deed.
• The condo's foreign quota is "to be confirmed" or the developer cannot put it in writing.
• The title is not a Chanote and the seller cannot explain the boundary survey.
• The villa was built before permits were issued, or extra floors were added later.
• A long lease is offered but the landowner refuses to register it.
• Land and building tax bills have not been paid; our land and building tax in Phuket guide explains who pays.

How long does it take and what happens next?

Phuket law firms generally say a condo check takes one to two weeks and a villa or land check two to three weeks, depending on the Land Office and the documents the seller provides. Make the deposit refundable if the checks fail, and plan the money transfer early: a foreign freehold condo purchase needs evidence that funds came from abroad, as described in our FET form Thailand guide. Then budget the costs on transfer day using our Phuket property transfer fees breakdown.

Done properly, property due diligence in Phuket costs a small fraction of the purchase price and gives you a written report you can rely on if a dispute ever arises.

FAQ: property due diligence in Phuket

Do I need a lawyer for property due diligence in Phuket?

It is not legally required, but an independent Thai lawyer, not one recommended by the seller or developer, is strongly advisable for any purchase or long lease.

Can I check a title deed myself?

You can view a plot's location and appraised value in the Department of Lands' LandsMaps service, but a certified copy of the deed usually needs the owner's authorisation.

Is a debt-free letter needed for a resale condo?

Yes. The Land Office will not register a condo transfer without a current debt-free certificate from the juristic person.

Should I pay a deposit before due diligence?

Only a small reservation fee, and only if the contract makes it refundable when the checks reveal a problem.
