A Firm Built on Deliberate Practice
Sirimongkol was established to fill a particular need: business litigation counsel that communicates clearly, assesses honestly, and prepares thoroughly — without the noise that surrounds much of commercial law marketing.
← Back to HomeHow Sirimongkol Came to Be
Sirimongkol opened its Bangkok office to work specifically with companies that find themselves in commercial disputes — and who want counsel that is straightforward about what the law can and cannot do for them. The firm was founded by practitioners who had spent years in larger settings and observed a recurring pattern: clients were often left to manage expectations that had been set too optimistically at the engagement's outset.
The practice is concentrated deliberately. We handle three categories of work — trial representation, mediation counsel, and pre-suit strategic memoranda — and we do not take every matter that comes through the door. That selectivity allows the team to give each client a level of attention that broader practices struggle to sustain.
Our office is in Khlong San, on the Thonburi side of the Chao Phraya. The address is deliberate: we are close to the Bangkok civil courts, the Central IP and International Trade Court, and the main arbitral venues — without being caught in the congestion of the central business district.
The Approach That Shapes Everything
We begin every new matter with a candid review of the position — including the parts that may not hold. That review shapes the advice that follows. If the matter is strong, we say so and explain why. If it carries material risk, that is communicated clearly, along with the options available.
Clients who come to us tend to be in-house counsel, CFOs, and business owners who need a clear answer before committing to a dispute. They are not looking for encouragement — they want a realistic picture of what the process involves, what it is likely to cost, and what a sensible range of outcomes looks like.
Settlement is treated as a legitimate outcome throughout the engagement, not a fallback when things go wrong. When a negotiated resolution makes sense for the client's business, we pursue it with the same care we would bring to trial preparation.

Commercial Litigation in Thailand — What It Involves
Commercial disputes in Thailand are heard primarily by the Civil Court and, for matters touching intellectual property, international trade, or certain contract categories, by the Central IP and International Trade Court. Both courts operate under procedures that differ in meaningful ways from common law jurisdictions, and businesses unfamiliar with Thai civil procedure often find that the documentary and witness preparation requirements are more demanding than expected.
The Thai Civil Procedure Code requires written pleadings that set out the factual and legal grounds clearly. Evidence is submitted in written form ahead of the hearing date; oral testimony is taken within that framework. The relationship between the pre-trial documentation and the witness examination is therefore tighter than in many adversarial systems, and poor preparation at the pleading stage tends to constrain the hearing.
Mediation has grown considerably as a first step — both through court-annexed programmes and through bodies such as the Thai Arbitration Institute. For disputes where the commercial relationship has value, or where the cost and time of full litigation would exceed the sum in dispute, a well-prepared mediation session can produce a settlement that serves both parties better than a judgment. Sirimongkol treats mediation engagement as a disciplined process, not a preliminary gesture.
For boards considering whether to proceed with a dispute, a pre-suit assessment can clarify the evidentiary position, identify documentary gaps, and outline the realistic range of outcomes. That kind of structured review — completed before a complaint is filed — is often the most cost-effective legal work a company can commission.
