Property scams in Thailand: the warning signs

Why foreign buyers are the preferred target

Fraud follows information asymmetry. A foreign buyer typically cannot read a Thai title deed, does not know what a Land Office search involves, is often buying remotely or on a compressed holiday timetable, and may be steered toward advisers introduced by the seller. None of these disadvantages is difficult to remove. All of them are routinely left in place.

Scheme one: the title that is not what it appears

Thailand has a hierarchy of land documents, and only the top of it, the Chanote (Nor Sor 4 Jor), represents fully surveyed, indisputable title. Below it sit possessory and use documents of descending strength, some of which cannot legally be sold or built on at all. The classic fraud presents a lesser document, or a photocopied or forged Chanote, to a buyer who cannot tell the difference. A related variant sells land whose deed is genuine but which is encumbered by a mortgage, a lease, or a servitude the buyer never hears about.

• The defeating check: a title search conducted at the relevant Land Office by your own lawyer, not the seller's. The original deed is held or mirrored there, and the back of the deed records every mortgage, lease and encumbrance in sequence.
• Verify the seller's identity against the registered owner, and trace the chain of prior transfers for anything abrupt or recent.
• For land, commission a survey check against the deed's boundary markers. Discrepancies between the ground and the document are common and negotiable before completion, ruinous after.

Scheme two: the double sale

Because a sale is only effective on registration at the Land Office, a dishonest seller can take deposits from several buyers against the same property, then register a transfer to one of them, or to none, and disappear. Off-market deals with long gaps between deposit and transfer are the natural habitat of this scheme. Condominium resales are not immune: a seller can collect a deposit while quietly borrowing against the unit, so the buyer completes into a mortgaged asset.

• Keep deposits modest and hold them in escrow with a law firm or a bank escrow facility, not in the seller's personal account.
• Compress the period between contract and registration. The shorter the gap, the smaller the window for mischief.
• Search the title again on the morning of transfer. A second search costs little and catches any encumbrance registered since the first.

Scheme three: the off-plan mirage

Off-plan fraud spans a spectrum. At one end is outright theft: renders, a show suite, a deposit account, and no intention to build. More common is the middle of the spectrum, a genuine developer who is undercapitalised, has not secured the environmental approvals or the construction permit, and is using buyer deposits as development finance. When the project stalls, buyers discover that their contracts give them a queue position behind the developer's bank. Phuket and the Eastern Seaboard have both produced well-known examples across cycles.

• Verify the developer company itself: registered capital, shareholder history, litigation record, and what happened to its previous projects. A special-purpose company with 1 million baht of capital selling 800 million baht of units is telling you the buyers are the bank.
• Confirm the land is owned or properly held by the project company and that the environmental approval and construction licence actually exist. These are checkable facts, not assurances.
• Prefer payment schedules tied to certified construction milestones, and check whether any escrow arrangement is real or decorative.
• For condominiums, confirm the foreign quota position early. Being sold a unit in an exhausted 49 percent quota is a recognised trap, and the fallback offer of a leasehold restructure is rarely what was paid for.

Scheme four: the yield that sells the deal

Guaranteed rental return schemes, typically 7 to 10 percent for 5 to 15 years, are the dominant marketing device in resort markets. Some are honoured. Many are simply a partial refund of an inflated purchase price, dressed as income, and they fail the moment the developer's sales pipeline slows. The guarantee is only as good as the covenant behind it, and the covenant is usually a thinly capitalised management company that can be dissolved without embarrassment.

The discipline here is valuation. Have the unit priced against genuine comparable sales without the guarantee, and treat the difference as the real cost of the promise. If the deal only works with the guaranteed yield, the deal does not work. A related warning sign is any scheme whose returns are paid partly in vouchers, stay credits, or points; income that cannot be banked is not income.

Scheme five: structures that fail quietly

Not every loss involves a villain. Some of the most expensive outcomes come from structures that were never sound: land held through a Thai company with arranged shareholders, now squarely in the sights of the nominee enforcement described in our separate briefing on the 2026 crackdown; 30-year leases sold as 90-year certainties on the strength of renewal clauses that do not bind a successor owner; or a Thai spouse purchase misunderstood by everyone involved. These fail slowly and legally, which makes them harder to recover from than a fraud.

If a structure is presented to you as what everybody does, ask the presenter to put the advice in writing on their firm's letterhead. The speed of the retreat is usually informative.

The diligence set, summarised

Calm, not complacent

The consistent theme is independence. Every fraud described above survives only when the buyer relies on the seller's lawyer, the seller's translator, and the seller's paperwork. The full diligence set on a significant purchase typically costs a fraction of one percent of the price and two to four weeks of patience, and it converts nearly all of these risks into non-events. Asia Global Partners coordinates that process end to end for clients, lawyers, valuers, structure review and Land Office attendance, so that the only surprises in a Thai property purchase are pleasant ones. When something does not withstand the checking, we say so plainly and early, which is occasionally unwelcome and always cheaper.

This briefing is general information, not legal, tax or investment advice. Thai rules change frequently and individual cases differ. Verify current requirements with the relevant authorities, including the Immigration Bureau, the Board of Investment, the Land Department, the Department of Business Development and the Revenue Department, and take advice on your own facts before acting.
