随着对外开放格局的进一步扩大，我国法院受理越来越多的涉外案件。在涉外案件中经常需要查明外国的法律法规，司法案例等相关内容。外国法查明在司法实践中是一个极为复杂和专业化的问题，也是国际私法领域中的一项重要内容。法官不能全面知悉各个国家的法律，案件中最终适用的某一项外国法律未必被法官所熟知。1988年最高人民法院《关于贯彻执行〈中华人民共和国民法通则〉若干问题的意见(试行)》第193条规定了一项重要的外国法查明方式——“中外法律专家提供”。 但在实务中，我国对于外国法查明专家的相关规定较少，外国法专家在具体的实践查明中存在困境。本文拟从以下几个部分进行研究。第一章，介绍我国目前关于外国法查明专家的相关立法情况，从聘请专家的两种方式，即当事人聘请的专家与法院委托的专家两种情形，结合司法实务中有关外国法查明争议的判例，讨论我国外国法查明中专家的资格标准不统一、专家意见的审查规则不完善、专家的权利与责任不明确等问题。第二章，针对实践中外国法查明存在的问题，明确有关专家的定义、范围、资格条件、专家的地位、专家意见的性质等内容，探讨专家资格应该包括的具体要求，专家的地位在诉讼中处于何种身份。第三章，从专家意见的审查，质证程序等环节进行分析，探究质证程序的规范流程，为完善外国法专家意见制度提供理论支持。第四章，参考国外专家意见的相关规定，分析外国法查明中专家的权利、义务与责任，出具错误的专家意见应承担的后果。第五章，针对以上提出的我国外国法查明中有关专家意见的问题，从明确专家的资格要求、规定专家意见的审查规则、建立专家意见采信的监督机制，明确专家的权利、义务与责任等方面，对我国的外国法专家意见规则提出建议。 本文从外国法查明中专家意见存在的问题出发，参考两大法系对于外国法查明中专家意见的实践经验，如英美法系的“专家证人制度”与大陆法系的“鉴定人制度”，对完善我国外国法查明中的专家意见规则提出可行性的参考建议。
