This thesis aims to study the expedited reorganization proceeding, by focusing on the duplication problem when debtor had negotiated with creditors and, later, entered into restructuring process. In order to reduce the unnecessary procedures, this study also examines the US’s prepackaged bankruptcy and France’s accelerated financing safeguard proceedings.The thesis concluded that the short length of bankruptcy proceedings can be applied to the Thai reorganization proceedings under the Bankruptcy Act B.C. 2483, especially, the proof of claims, the plan formulation, and voting on and acceptance of the plan. Therefore, it is recommended that the Bankruptcy Act B.C. 2483 should be amended in order to solve the overlapping procedures, quicken the proceeding, and potentially save the costs of Thai reorganization proceedings. The expedited reorganization proceedings should be an option for debtors in the restructuring process.
