Legal informatics is the theory and practice of information management within a legal system.

The interaction between information technology and law is dynamic.

The operators of a legal system (judges, lawyers, ordinary citizens) to achieve their objectives process data about the world (for example, in order to get the evidence of who did what and when). At the same time they manage information about the legal system itself (court rulings, contracts, statutes).

Although the concept of legal informatics is not new, its importance has grown enormously thanks to recent technological advances - including progress on big data, machine learning and autonomous systems (such as cars and robots), as well as the globalization of the Internet.

The result of these advances is the emergence of new professional figures (the data protection officer, the data legal analyst) who have specific training needs.

The technological impact is capable of radically changing legal professions, legal services and disrupting the way the legal system works for both professionals working in the legal system and ordinary citizens who are asking for new tools to understand and solve legal problems.
