The reform of the judicial system should not only cover the trial system, but also the compulsory enforcement system. If the obligor is unable to effectively enforce his rights in accordance with the title of enforcement granted from the trial procedure, such frustration may result in the obligor's distrust to, or apartness from, the judicial system. In the matter of compulsory enforcement, for the purpose of properly protect the obligor's rights, the initial measurement is to secure the obligor's awareness of the ist, as well as the location, of obligee's subject matter properties. It enables the obligor to specify the property scope subject to the compulsory enforcement, which makes the debts in subject collectable and enforceable. Accordingly, the current Compulsory Enforcement Law provides the obligee property reporting system. This property reporting system grants access to the obligee's property information and the obligor may therefore acknowledge the subject matter properties or deliverables. Nevertheless, it is criticized that such system is ineffective but symbolic. In addition, in the practice of compulsory enforcement, more than forty (40) percent of cases are concluded by issuing the debt certificate, rather than by fully compensating the obligor. It becomes crucial to study the following topics, including (1) What are the procedure and context of the aforementioned property reporting system; (2) From the comparative law prospective, how does the local law differentiate from the foreign property discovery systems; (3) Does the local procedure or system carry out its functions and effectiveness; and (4) If it does not, how should we improve it? This study refers to the evolution of property discovery system in Germany, Korea and Japan, comments on the strength and shortfalls of Taiwan property reporting system, and intends to solve the issues from the methodology of law interpretation, law application and legislation amendment. This study is necessary and beneficial to enhance Taiwan property discovery system, to prevent the obligee from hiding his properties, and eventually secure the obligor the effectiveness of compulsory enforcement.
