JM

James Morley

British national, Bangkok

I used Thammasak for the purchase of a condominium on Sathorn Road. As a foreign national, I had concerns about the ownership structure and wanted to be certain the title deed was unencumbered. Nattaya walked through everything in plain language, verified the title at the Land Office, and attended the transfer with me. Nothing was rushed and I never felt I was being pushed into a decision.

Siriwan Khomchai

Director, Artisan Textile Co. Ltd, Bangkok

We engaged Thammasak to register the trademark for our fabric brand. Panya conducted a thorough search first, which revealed a potential conflict we had not been aware of — his advice on how to address this before filing saved us from what could have been a costly problem later. The documentation was well prepared and the process was clearly explained throughout. We have since referred two business associates.

Benjamin Hartmann

Managing Director, EHM Consulting Asia

Our company engaged Thammasak for corporate governance advisory about eighteen months ago, ahead of a due diligence process for a potential investor. Wichai's quarterly reports gave us a clear picture of where our documentation stood and what needed to be addressed before the review. The investor's legal team commented favourably on the quality of our governance records. The advisory consultation hours have also been genuinely useful between quarterly reviews.

Pranee Tangtrakul

Founder, Tangtrakul Studio, Chiang Mai

I came to Thammasak wanting to register copyright protection for a collection of graphic designs used in our product line. I had not spoken to a lawyer before and was not certain what I was entitled to or how the process worked. Panya was patient in explaining the distinctions between copyright and trademark and which was more relevant to what I was trying to protect. The consultation itself was clarifying. I came away knowing what to do and why.

Ravindra Nair

Indian national, property investor, Bangkok

I have completed two property acquisitions in Bangkok through Thammasak, one in 2022 and one late last year. Both were handled by Nattaya. The process on both occasions was methodical — she identified an issue with the lease agreement on the second transaction that would have caused complications and had it corrected before we proceeded. English communication throughout was clear and responsive. I would not undertake a Thai property transaction without legal support of this kind.

Wanpen Laohachai

CFO, Pinnacle Manufacturing Ltd, Bangkok

We are a mid-sized manufacturing company with thirteen shareholders and had allowed our governance documentation to become disorganised over several years of rapid growth. Thammasak's quarterly review service has given our board a structured process for keeping records in order. The written reports have been particularly useful for our internal auditors, who have noted the improvement in documentation quality since we began the arrangement two years ago.

Software Company — Trademark Registration, Bangkok

Intellectual Property — January to March 2026

The Situation

A Bangkok-based software development company had been trading under its brand name for four years without formal trademark registration. The founders became aware that a similar name was being used by a newer entity in the same sector and wanted to establish prior claim through official registration.

What We Did

Panya conducted a comprehensive trademark search across the DIP database and relevant international classes. The search confirmed prior use and supported the registration application. Documentation was prepared and filed within the agreed three-week preparation period. A response to an office action from the DIP was also handled during the examination phase.

The Outcome

The trademark application was accepted by the Department of Intellectual Property and proceeded to publication. The company now holds an official registered trademark, providing the formal legal basis for asserting its rights to the brand name in future commercial or legal contexts.

Australian Couple — Condominium Purchase, Bangkok

Real Estate Transaction — October to November 2025

The Situation

An Australian couple relocating to Bangkok for work sought to purchase a condominium in the Silom area. As foreign nationals, they needed confirmation that the unit fell within the foreign ownership quota for the building and that the title was unencumbered. They had received a standard sale and purchase agreement from the developer's agent.

What We Did

Nattaya verified the foreign ownership quota status of the building at the Land Office and confirmed the title deed was free of encumbrances and mortgages. She reviewed the sale and purchase agreement and identified several clauses that were unfavourable to the buyers, recommending specific amendments. A supplementary agreement was drafted to address payment staging concerns.

The Outcome

The developer accepted the proposed amendments. The transfer was completed at the Land Office with Nattaya in attendance. The clients received a clean transfer of title within the foreign ownership quota, with contractual terms that reflected their interests rather than those of the developer's standard form agreement.

Distribution Company — Governance Restructure, Bangkok

Corporate Governance Advisory — Ongoing since 2024

The Situation

A distribution company with eight shareholders and a mixed Thai and foreign board had accumulated several years of undocumented board decisions and informally convened shareholder meetings. The company was in preliminary discussions about a strategic acquisition and needed its governance records to withstand due diligence scrutiny.

What We Did

Wichai conducted an initial governance audit, identifying the gaps between actual practice and the requirements of the Civil and Commercial Code. A structured remediation plan was prepared to document prior decisions correctly and establish proper meeting procedures going forward. The company then entered the ongoing quarterly advisory arrangement.

The Outcome

Within two quarters, the governance records were sufficiently structured to proceed with the due diligence process. The acquiring party's legal team found no material governance issues. The company continues on the quarterly advisory arrangement to maintain the standard reached during the remediation period.
