Triage for advisers and family offices.

Who this is written for

This piece is written for family office managers, private client advisers, trustees and in house counsel who hold responsibility for a portfolio containing Thai property or Thai companies, rather than for the principal. Its purpose is triage: a repeatable way to sort a book of clients into those who need immediate independent Thai legal advice, those who need a review scheduled, and those whose position is straightforward. It is general information and not legal advice, and nothing here substitutes for counsel on any individual file.

Why triage is now a portfolio question

Two administrative changes moved this from an ad hoc matter to a portfolio one. From 1 January 2026 the Department of Business Development has required documentary proof of source of funds for 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. The second change is the one that affects a portfolio, because amendment filings are routine. Any client with a Thai company will make one eventually, on a director change, an address change or a share transfer, and each is now a point at which a dormant file is read.

It is further reported that examination has been extended across a large number of companies for nominee indicators, that data analysis across company registration and land transaction records is being used to identify patterns, and that Phuket, Koh Samui and Koh Phangan are focus areas, with tourism, real estate and land trading, hotels and resorts, agriculture, logistics and e-commerce, and construction among the sectors treated as higher risk. Report all of this to a principal as reported and dated direction of travel, verifiable with the Department of Business Development and with counsel, not as settled fact.

The five questions that sort urgent from stable

These five questions can be answered from the file, or in a fifteen minute call with the client, without any legal analysis. They do not determine legality, which is entirely a matter for Thai counsel. They determine sequence.

• What is the holding form, precisely? A condominium unit held in foreign freehold within the building's foreign quota with remittance evidence sits very differently from land held through a company, or from a lease with a renewal promise attached.
• Who are the Thai shareholders, if there are any, and did they pay for their shares with their own money? If the client cannot answer, or answers with a description of an arrangement rather than a transaction, that file is not stable.
• Is any triggering event foreseeable in the next twelve months? A sale, a refinance, a director or address change, an ageing or ill principal, a marriage under strain, an ageing local nominee, or a partnership dispute.
• Can the client evidence the funding, from the original purchase to the present? Remittance records, bank statements, subscription payments and loan account support, held somewhere retrievable.
• Who can act in Thailand tomorrow morning, and is that person's authority current? Named individual, current mandate, valid power of attorney where one is needed.

A file that answers all five cleanly is stable, and should be reviewed on a normal cycle. A file that fails question two or question four should be referred to Thai counsel promptly. A file that fails question three as well should be referred now, because the client is about to be examined by an event rather than by choice.

A simple sorting grid

What triage looks like on a real book

The following is a composite drawn from situations advisers in this market see repeatedly, not an account of any individual client. An office holds eleven files with Thai exposure. Seven are condominium units held in foreign freehold with remittance evidence on file, and they sort into monitor within an hour. Three are villas held through companies formed more than a decade ago by three different local firms, and none of the three clients can answer the second question about who paid for the Thai shares. One of those three has an ageing principal and a director who wishes to resign, which makes an amendment filing likely within the year. That file moves to the top, and the other two are booked for review in the same quarter so that counsel reads three related structures at once rather than three separately.

The observation for an adviser is about ordering rather than alarm. All three company files had the same options available to them. The one with a foreseeable filing has the shortest period in which to choose between those options, and that is the only reason it goes first.

Briefing the principal without alarming them

The tone of the first conversation determines whether the work gets done. Principals who are frightened either act rashly or refuse to engage, and both outcomes are worse than a measured review. Four practical points help. Lead with the mechanism rather than the penalty: explain that ordinary events now cause files to be read, which is a fact about administration and not an accusation about the client. Be explicit that you are not offering a legal conclusion and that only Thai counsel can give one. Present the review as normal portfolio hygiene of the same order as a title check or an insurance review. And be clear about what the review will and will not tell them, so that the deliverable is understood in advance.

It also helps to say early that the Thai parties in a structure carry exposure too. Under Section 36 of the Foreign Business Act B.E. 2542, a Thai national or entity holding shares on behalf of a foreigner commits an offence, with a stated penalty of imprisonment not exceeding three years, a fine of 100,000 to 1,000,000 baht, or both, and liability falls on both the foreigner and the Thai party. Many principals engage with the review far more readily once they understand that a spouse, a long standing employee or a local partner may be carrying risk on their behalf.

Instructing Thai counsel efficiently

Counsel's time is wasted mostly on document gathering, so the adviser's contribution is to arrive with a complete file and a defined question. Send the corporate documents, the title documents, the funding history with remittance evidence, the bank mandate, the last three years of filings, and a short chronology of the structure from purchase to date. Ask for a written opinion rather than a conversation. Specify the questions you need answered, including the lawful alternatives available on these facts and their limitations. And instruct counsel who did not form the company, because an opinion on whether a structure is sound should not be sought from the firm that built it.

One instruction should be standard on every file: the client must be complete with counsel, including about anything informal or undocumented. Advisers occasionally soften a client's history when passing it on, out of discretion. It produces advice that fails on contact with the first diligence enquiry, and it is not discretion, it is a defect in the instruction.

Where a coordinating office fits

Asia Global Partners is a private office and not a law firm, and gives no legal advice. For advisers running a portfolio at distance, the office functions as the coordinating layer in Thailand: instructing and managing independent Thai counsel, accountants and valuers, assembling documents locally, attending where attendance is required, and reporting back in a form an adviser can put in front of a principal. The adviser keeps the client relationship and the home country advice; the office holds the Thai process together. A confidential structure review is the usual first instruction.

The observation that matters for a portfolio is a statistical one rather than a dramatic one. Across a book of clients, the proportion facing a triggering event in any given year is small, and the proportion facing one over five years is not. Files reviewed in advance of their trigger are handled at leisure and at predictable cost. Files reviewed after it are handled at somebody else's pace.

This article is general information and not legal advice, and triage is not a legal conclusion. Every file placed in any band should be referred to independently instructed Thai counsel for advice on its own facts, and clients must be complete with that counsel. Verify company, shareholder and source of funds requirements with the Department of Business Development, land and title questions with the Land Department, and promotion questions with the Board of Investment.

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.
