当执行机关在进行民事强制执行时，由于现有执行机制的缺陷以及其它各种主客观原因而引起执行错误或执行不当，对执行机关或利害关系人的合法权益造成损害的，需要对此侵害进行补救。为此，各国纷纷建立了执行救济制度。而民事执行异议之诉作为一种实体救济机制，得到了各国强制执行理论和立法的关注，已成为民事执行救济不可或缺的一部份。但由于我国理论研究的不足，立法的偏颇等原因，我国并未建立起异议之诉制度。现行民事诉讼法规定的案外人异议制度本身存在诸多缺陷，造成我国在强制执行中当事人和第三人的合法权利没有得到有效的保护。本文主要是在借鉴大陆法系国家和我国台湾地区有关执行异议之诉制度的立法经验的前提下，结合执行工作实践，运用法学基本理论知识，为建立和完善我国的执行异议之诉制度提出构想，以期解决“执行乱，执行难”问题，实现司法公正。

In the course of civil enforcement, the rights of the parties and strangers face the possibility of being violated. Thus, many countries set up the civil forceful implementation system to ensure the civil right of people.As a main method of forceful implementation，the lawsuit of enforcement is paid mush attention by scholars and legislation in many countries. Since the legislation in the civil forceful implementation system of China is weak, the lawsuit of enforcement has not been set up yet. As the replacement of the lawsuit of enforcement, the stranger dissent in our country has a lot of shortcomings. As a result, the civil right of people cannot be protected quite well. My paper will analyze the stranger dissent in our country first,and then introduce the lawsuit of enforcement system abroad. Finally, basing on the legislative experience of other countries and our Taiwan district, this paper tries to propose some suggestions for setting up the lawsuit of enforcement in our country, including some exact plans about the procedure, the parties and the judgment, etc.
