The sale that collapsed in diligence.

How the transaction actually dies

The pattern below is a composite drawn from situations advisers in this market see repeatedly, not an account of any individual client. A price is agreed. Both sides are pleased. The seller sends the title documents and the company papers to the buyer's lawyer, expecting a week of formality. Instead a schedule of enquiries comes back, and the enquiries are not about the roof. They are about who subscribed for the shares in the holding company, where the subscription money came from, whether the Thai shareholders have ever received a dividend or attended a meeting, who has funded the company since incorporation, who gives the bank its instructions, what the director's loan account represents, and whether the registered objects of the company match what the company has actually been doing.

The seller can answer some of these and not others. The answers he can give do not sit comfortably beside the documents, and the documents do not entirely agree with each other. From that point the transaction usually does not fail in an argument. It fails in silence. The buyer's lawyer reports that the risk cannot be quantified within the timetable, the buyer's enthusiasm cools by degrees, an offer that was firm becomes conditional, the conditions become a longer list, and eventually the emails stop.

What diligence now asks that it did not ask before

Buyers and their lawyers have changed their questions because the environment changed around them. From 1 January 2026 the Department of Business Development has required documentary proof of source of funds on newly incorporated Thai companies, with registrars verifying that each Thai shareholder had genuine financial capacity for the paid up capital declared. From 1 April 2026 those checks were reported to have been extended to company amendment filings. A buyer acquiring shares in a Thai company, or acquiring a property whose transfer will require corporate changes, is buying a file that will one day be looked at. Prudent counsel therefore looks at it first. The direction of travel here is reported and dated rather than permanent, and current requirements should be verified with the Department of Business Development and with counsel.

In practice the questions cluster into five areas: who really owns the company and can that be evidenced; where the money came from at each stage; whether the Thai shareholders are real participants with capital genuinely at risk; whether the corporate records, the bank records and the land records tell one consistent story; and whether the property itself carries anything unexpected on title. None of that is exotic. It is the standard diligence any competent lawyer would run on a corporate asset anywhere. What is new is that it is now run on holiday villas.

Why the price falls once a defect is visible

There is a commercial mechanic here worth understanding, because sellers routinely misread it as bad faith. A buyer who can see an unresolved question does not price the question at its likely cost. He prices it at his worst plausible case, plus something for the time and fees he will spend resolving it, plus something for the fact that he cannot resell easily until it is resolved. That is why the discount demanded for a structural defect is usually larger than the cost of curing the same defect would have been if the seller had cured it himself before going to market.

The second mechanic is the market's memory. A property that has been withdrawn once, or that has been through two failed transactions, acquires a reputation among the small number of agents and lawyers who handle work at this level. The next buyer starts from a lower opening position, because the story reached him before the particulars did.

What the seller should have done twelve months earlier

The single most valuable thing a seller can do is discover their own position before a counterparty does, and do it early enough that the discovery is not attached to a deadline. In practical terms that means instructing Thai counsel who did not form the company to read the file and give a written opinion; assembling the funding history properly, including the original remittance evidence where the purchase money came from abroad; reconciling the corporate records with the land records and the bank records; and then taking whatever lawful step counsel advises, whether that is a correction, a conversion to a lawful holding form, the introduction of genuine Thai capital and governance, or a decision to sell in full knowledge of what will be disclosed.

• Instruct independent Thai counsel to review the structure and give a written opinion, well before any marketing begins.
• Assemble the funding trail from the original purchase forward, including remittance and bank evidence held abroad.
• Reconcile the share register, the statutory books, the bank mandate and the title documents so that they agree.
• Identify who will need to sign, and where they will physically be, at each stage of a transfer.
• Take advice on Thai transfer duties, withholding and any business tax that may arise, and involve your advisers at home on your own reporting obligations.
• Decide, with advice, whether to correct the position before marketing or to market with full disclosure of it.

What a seller must not do when a question is raised

This has to be said directly. If a buyer's lawyer raises a question the seller cannot answer, the answer is not to manage the appearance of the file. Nothing in a legitimate sale process involves adjusting records, delaying disclosure, or giving a counterparty an account the seller knows to be incomplete. Beyond the obvious ethical objection, it converts a commercial problem into a personal legal one, and it exposes the Thai people involved in the structure as well as the foreign owner. The lawful response to an unanswerable question is to stop, instruct qualified Thai counsel of the seller's own, tell them everything including the parts that are embarrassing, and act on their advice about disclosure and about the transaction.

Sellers sometimes fear that candour with their own lawyer will make matters worse. It does the opposite. A lawyer who has the complete picture can identify a lawful route; a lawyer working from an edited version will produce advice that fails at the first contact with a diligence enquiry.

Sequencing an honest sale

An orderly sale runs in a particular order, and the order is what protects the price. Review first, correct or convert second, prepare the disclosure file third, appoint the agent fourth, and negotiate last. Sellers who reverse this, appointing the agent first and reviewing only when a buyer forces it, spend the whole transaction reacting. Where the structure cannot be corrected on the seller's facts, counsel may still advise that a sale is the right outcome, in which case the sale proceeds with the position disclosed and priced honestly rather than discovered.

Asia Global Partners is a private office and not a law firm, and gives no legal advice. Its role in a matter of this kind is to instruct and coordinate independent Thai counsel, accountants and valuers, keep the seller's advisers at home involved where home country obligations arise, and hold the sequence together so that nothing is discovered by a counterparty first. A confidential structure review, taken before a property is marketed, is the version of this work that costs the least.

The quiet observation

Twelve months before a sale, the owner has every lawful option his facts permit, an unhurried timetable, and the ability to choose which buyer sees what and when. On the day a buyer's lawyer raises the first question, most of those options are still theoretically available, but each now has a deadline attached and a counterparty watching. Six months after a collapsed transaction, the options are the same again, only the property now carries a history. Nothing forecloses permanently. What changes is the price of each remaining route, and the direction of that change is consistent.

This article is general information and not legal advice, and no sale should be structured on the basis of it. Instruct independently instructed Thai counsel on your own facts and be complete with them. Verify company filing and source of funds requirements with the Department of Business Development, title and transfer requirements with the Land Department, and transfer duty, withholding and business tax questions with the Revenue Department and your own tax advisers.

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.
