The Legal Informatics and Legal Information Technology (LIT) Workshop is an annual event which gathers people interested in broadly understood Legal Informatics and its applications. The LIT 2013 meeting will take place in Poznań, Poland as part of the 16th International Conference on Business Information Systems. As a continuation of previous editions, we invite people dealing with different domains closely related to legal matter and Information Technology. The 5th Legal Informatics and Legal Information Technology Workshop will be a multi-disciplinary, one-day workshop that will bring together practitioners and researchers to investigate challenges and opportunities in the emerging trends on the verge of law and IT. The workshop will examine vital issues, including law-related business processes, legal ontologies, description frameworks, discussing new research and innovative applications in Law, Information Technology as well as Insurance. The workshop is receptive to all papers dealing with any topic in these interdisciplinary domains. In the year 2011 all papers accepted to the workshop have been published in Springer Series: Lecture Notes in Business Information Processing. We are planning to continue the cooperation with the publisher on this edition of the event.
