We present an innovative approach to support lawyers in the processes of contract drafting, editing and analysis. Legal comments on German tenancy law contain condensed knowledge that supports contract writers. Our approach supports lawyers by providing relevant information from legal comments and practitioner books. Our approach allows to select an arbitrary length text passage of interest and displays relevant corresponding information inline. It is based on text relatedness measures, in particular tf-idf and word embeddings, and is an instance of the semantic text matching problem.
