    Thai Arbitration Act: Applicability + Foreign Award Enforcement

    TL;DR

    The Arbitration Act B.E. 2545 (2002) is modelled on the UNCITRAL Model Law on International Commercial Arbitration. Thailand acceded to the New York Convention in 1959; foreign arbitral awards are enforced via the Civil Court under Sections 41-45. Domestic arbitration is widely used in construction, supply, and licensing disputes. Thailand Arbitration Center (THAC, ศูนย์อนุญาโตตุลาการระหว่างประเทศแห่งประเทศไทย) and Thai Arbitration Institute (TAI, สถาบันอนุญาโตตุลาการ) are the principal institutions.

    Arbitrability + Public Policy

    • Most commercial disputes are arbitrable.
    • Restrictions: criminal, family, certain administrative-public matters.
    • Public policy ground for refusal (commonly narrow).

    Award Enforcement Steps

    1. Petition Civil Court with award + arbitration agreement.
    2. Authentication / translation of foreign award.
    3. Court reviews against limited grounds (NY Convention Article V).
    4. Court enforces as a judgment.

    Common Mistakes

    • Skipping mediation step where contract requires.
    • Late challenge to jurisdiction (must be early per §22).

    FAQs

    1. Foreign arbitrators?

    Permitted; visa rules and work-permit for in-Thailand sittings need attention.
