The Thai Arbitration Institute (TAI), a division of Thailand’s Office of the Judiciary, has taken a step toward harmonizing the tools available for dispute resolution. On August 8, 2025, the institute formally launched the TAI Mediation Center (TAI-MC). Although the amendments to TAI’s Arbitration Rules that will govern the TAI-MC have not yet been finalized, the framework now under consideration suggests that TAI is positioning itself to become a more attractive venue for commercial dispute resolution.
In the regime contemplated under the current version of the amendments, TAI proceedings will adopt an “arbitration-annexed mediation” mechanism—commonly termed the “Med-Arb” model—while preserving the procedural safeguards indispensable to arbitral neutrality. Mediation will be entrusted to a separate, dedicated mediator appointed under the TAI-MC who is precluded from serving on the arbitral tribunal in the same matter. By clearly separating the functions of mediator and arbitrator, the institute eliminates any risk that confidential information disclosed during mediation could influence the adjudicatory outcome if the parties do not settle. Only when all parties subsequently make a request may that same mediator assume arbitral duties in the case.
The parties will retain substantial autonomy in selecting the mediator. They may either designate a mediator by mutual consent or invite the TAI-MC to appoint one from its authorized panel. TAI has announced its intention to curate that panel with particular emphasis on commercial expertise and cross-cultural negotiation skills, supplemented by ongoing professional training. Where the parties cannot agree on remuneration, the mediator’s fee will default to a tariff comparable to the TAI-MC’s cost schedule, which under the current version of the amendments will be approximately THB 45,000 for disputes in which the aggregate claims do not exceed THB 10 million, with incremental increases tied to higher claim values. This predictable cost matrix is aimed at enhancing transparency and
