Thai law contains no provision that speaks directly to what happens to an arbitration when one of the parties becomes insolvent. The interaction between arbitration and insolvency is derived instead from the general operation of two separately drafted laws: the Bankruptcy Act B.E. 2483 (1940) and the Arbitration Act B.E. 2545 (2002). Because Thai courts have had few opportunities to interpret how these two statutes apply together, the practical answer to many questions, such as who represents an insolvent party in arbitration, whether an award will be enforced, and what happens to a foreign proceeding, depends on inference from general principles of insolvency, arbitration, and procedural law rather than on settled rules. Liquidation and Restructuring The Bankruptcy Act governs both liquidation, which winds up a debtor’s affairs, and restructuring (rehabilitation), which aims to preserve a business. The consequences for arbitration differ accordingly. In liquidation, the debtor’s assets vest in the official receiver, who alone can conduct or continue any arbitration affecting the estate; the debtor loses the authority to act on its own behalf. In restructuring, the plan preparer or administrator takes over that role, but there is more room for the debtor to remain involved, since the objective of rehabilitation is to keep the business operational. Restructuring carries an automatic stay that takes effect once the Bankruptcy Court accepts the restructuring petition. This stay can halt an arbitration regardless of where it is seated. In contrast, liquidation does not work through a stay; instead, the debtor’s loss of authority over its own assets and disputes is what constrains the arbitration. Neither proceeding provides a party a formal route to apply for permission to continue arbitrating—the Bankruptcy Act contains no such mechanism—though in restructuring cases the Bankruptcy Court may allow proceedings to continue where doing so will not prejudice

Employers operating in Thailand can enforce post-employment noncompete covenants, but success depends on precise drafting and strong evidentiary support. Thai courts will uphold restraints that protect legitimate employer interests and are fair and reasonable in duration, geographic reach, and substantive scope. Overbroad covenants, however, draw judicial skepticism and may fail unless they are drafted in severable, defensible components tied to the employee’s actual role. This article synthesizes recent trends in Thai case practice, explains how Thai courts assess reasonableness in employment restraints, and provides a practical litigation-focused framework for drafting enforceable covenants, preparing evidence, and pursuing relief through the Labor Court. The Legal Framework and Its Practical Implications Thai courts evaluate noncompete covenants under general principles of contract enforceability and public policy, with particular focus on whether a restraint is necessary to protect a legitimate employer interest and proportionate to that objective. In employment matters, this analysis is shaped by the employee-protective tenor of Thai labor law and by the Labor Court’s equitable discretion in determining appropriate remedies. The practical takeaway is that standardized or broadly drafted covenants rarely survive scrutiny. Courts look for a demonstrable nexus between the employee’s actual exposure to confidential information, trade secrets, or customer relationships and the scope of the restraint. Where that nexus is weak or the restraint operates as a blanket prohibition, courts are inclined to decline enforcement or limit relief to a narrowly tailored prohibition. The employer interests most commonly recognized as legitimate in Thai practice include the protection of trade secrets, confidential business information, and goodwill tied to identifiable customer segments or territories. Courts are more likely to enforce restraints where employers can clearly document what information is at risk, why particular customer relationships matter, and how the employee was involved with those assets. Judges also look closely at the
