Abstract: Non-litigation case and litigation case are the two basic classifications of civil case.However,for quite a long time in China,no sufficient study has been given to non-litigation case in the field of civil procedure law to meet the demand of market economy and the changing social structure.Thus foreign investigation on the nature and range of non-litigation case will provide reference for us to deepen the study of litigation case and non-litigation procedure,so that non-litigation procedure may play a positive role in preventing disputes and stabilizing social order.

Key words: non-litigation case, nature and range, foreign investigation
