About the Firm

A modern firm built for businesses and investors in Thailand.

We combine the rigour and structure of a large international firm with the agility, accessibility, and efficiency of a focused team — and we do it in your language.

Who we are

Lawyers, accountants, and immigration specialists — under one roof

Khonsu Legal serves the foreign community in Thailand. Our clients are entrepreneurs starting a business, investors buying property, families relocating long-term, and established companies navigating compliance.

What unites them is a simple frustration: Thai law and Thai bureaucracy are intricate, opaque, and unforgiving — and most service providers do not explain them in a way a foreign client can act on. We exist to close that gap. Every engagement starts with a clear conversation about what you actually want to achieve. Every step is documented. Every document is explained.

The name Khonsu comes from the Egyptian god of the moon — the wayfinder who guided travellers through the night. In that sense, the darkness is the unfamiliarity foreign clients encounter when they arrive. Khonsu is the light that shows the path.

How we work

A few things define how we operate, on every engagement:

  • In-house, end-to-end. No intermediaries, no outsourcing. The lawyer who scopes your matter is the same lawyer who files it.
  • Plain language. We use the Thai legal terminology where it matters — and then we tell you what it means in your language.
  • One contact, the whole way through. Each client is assigned a named point of contact who stays with them across every service we deliver.
  • Senior specialists, not juniors. Every matter is led by an experienced lawyer or accountant in the relevant field. We put strong people on the work rather than saving money on who does it — so it's done properly the first time.
  • Proactive, not passive. We're focused on the outcome — so we push each matter forward instead of letting it drift, anticipate the next step, flag issues early, and come to you with solutions, not just status updates. Momentum is part of the service.

We work nationwide. Most filings are now handled online, and we travel to other provinces when an in-person visit is needed. In many provinces, we also have local representatives who file with government offices on our behalf, while all documents are prepared in-house at our offices in Phuket and Bangkok.

What we focus on

We do a few things, but we do them properly.

We're not a general practice, and we don't try to be. Our work centres on corporate structuring, real estate transactions, and M&A, backed by accounting and tax. Our immigration practice is intentionally narrow and Thailand-only — three visa routes for founders, investors, and staff, not marriage, retirement, student, DTV, or tourist visas, and no visas for other countries. We also don't take on criminal or personal-injury cases, or everyday paperwork like driver's licences. We'd rather be genuinely good at a few things than average at many — and that focus is what lets us go deep on the work clients actually come to us for.
