Abstract
A land and house investigator is a holder of the national qualification as an investigator who, by the request of others, examines and surveys such matters as where lands and houses are located, and in what form, as well as how they are being utilized, and carries out tasks such as the production of drawings and the procedure of application for registration regarding the description of real property. And, although the holder of the qualification is familiar to citizens as it is possible to casually consult the holder as a consultant about problems, or troubles with neighbors, in life scenes and production sites of land, buildings, roads and local areas, the current reality is that the recognition by citizens is not so high because of such reasons as the obscureness of the naming of the land and house investigator. Thus, in this paper, the role and historical development of the land and house investigator will be discussed by looking back at its history and at various instituted systems. Further, an outline and perspective of ADR (Boundary Dispute Consultation Center) by Land and House Investigators' Associations in collaboration with lawyers, which were born amidst the currents of reform of the judicial system, will be discussed also.
