TopIntroduction
The rapid development of information technology is accelerating diverse changes in society as a whole, leading to innovative and customer-oriented changes not only in corporate organizations but also in the public sector. The emergence of the e-government is helping the expansion of universal administrative services for the public by enabling electronic processing in various administrative services and the e-government is rapidly spreading to various fields because it satisfies the national needs for administrative services. In particular, the use of the electronic litigation system for legal services has been explosively increasing after its introduction because it has the advantage of expanding the accessibility of the public to the legal system and dramatically reducing the cost and time of legal services. The expansion of electronic litigation services has important implications in terms of improving the efficiency, transparency, and reliability of legal administrative services along with the expansion of universal legal services to the general public, but due to the recent changes in the industries triggered by the fourth industrial revolution, Legaltech based on big data and artificial intelligence began to appear as an area of industrial services for electronic litigations that have been centered on simple electronic document processing. The characteristic of the Legaltech industry is that it is a new legal service industry that converts vast amounts of litigation information into big data and combines artificial intelligence in interpreting such legal information, and is known to provide commercialized services in major advanced countries (Rehder & Van Elten, 2019).
Currently, in the legal service market, diverse changes are being introduced to meet intensifying competition and various social demands in the legal service market targeting a small number of expert groups. For example, as the number of cases accepted per person decreases and the market changes and competition intensify, market-oriented changes are emerging, such as moving away from the market centered on experts with legal knowledge and providing counseling services with lawyers through various channels beginning from search for lawyers. That is, due to the expansion of the electronic litigation system and the intensification of competition, electronic litigations are expected to turn into a catalyst for another change. Such a change is judged to require an approach that can lead to actual expansion of the use of the electronic litigation system from the viewpoint of service users and potential customers before the improvement of the electronic litigation system and technology (Chung, 2014).
As a useful model for predicting user behaviors related to the acceptance of innovative technologies as such, the Technology Acceptance Model (TAM) is widely used in related studies. The TAM has been mainly used to identify the process leading to behaviors such as continuous use or acceptance of related information services with users of information systems based on new information technology, such as the electronic litigation system. In particular, the expanded TAM has advantages that social or personal characteristic factors can be set as external leading variables that affect perceived ease and perceived ease of use presented in the TAM, and that in addition to perceived ease of use and perceived usefulness, new variables can be input depending on perspectives by researcher to verify the relationships (Venkatesh & Morris, 2003; McFarland & Hamilton, 2006; Chung, 2014)
As examined, although the importance of electronic litigations has been magnified because the necessity of non-contact legal services has been emerging due to the corona situation along with the emergence of a new legal service market called Legaltech, few studies on the characteristics or behavior of users of the electronic litigation system have been conducted and supplier-oriented market characteristics exist thus far so that the expansion of diverse legal services and the launch of customer-oriented legal service products into the market have been slowly implemented.
