The Thai Arbitration Institute (TAI) — currently under the auspices of the Thai government’s judiciary — is the most commonly chosen institutional arbitration service provider by commercial parties to administer their contractual dispute arbitrations seated in Thailand. Unless the parties agree to deviate from the TAI Rules — and somewhat controversially — “with the consent of the Director of the Alternative Dispute Resolution Office”, the TAI Rules will apply to any arbitration proceeding under its administration.
