Expert auxiliary system is newly established by procedure laws in China in recent years. Whether at the theoretical research level, or at the legislative level, and even at the level of practice, expert auxiliary personal qualiifcation identifying standards and procedures are quite inadequate. In the outside, there are some similar systems, such as expert witness system in Anglo-American law system, friends of the court in the United States, the British technical jury, Italy’s technology consultant, Japan''s lawsuit assistants, etc. These countries have established the corresponding standards and procedures of expert qualiifcation examination and identiifcation. In reference to the relevant laws and regulations from other countries and regions and combining with China’s real conditions, the author will give suggestions from three aspects: the specialist aided person''s qualiifcation standards, qualiifcation review procedures, and other auxiliary system.
