Advice on activities/lessons for a ESL learner who is a Lawyer?

I have a student who is studying to be a Lawyer and does an internship with a very big Law Firm. Her English is Advanced as far as listening and reading comprehension and Upper Intermediate for Speaking and Writing. The institute I work for did a diagnostic for her to start which told me her specific grammar weaknesses. I taught her all of those diagnosed areas of grammar weakness, as well as some that I noticed during our classes, and she knows them and can use them quite well now. I have her for 3 hours a day (in a row) 5 days a week and outside of the conversation, reading related legal documents and answering questions/summarizing, I am running out of ideas of what to do to keep the class varied and interesting. Does anyone have any suggestions/ideas for innovative/interesting activities to do with her than would provide value to a Lawyer in training? Please don't just say legal vocab, we are studying that already. I would be interested in any games/activities that I could work the legal vocab into for practice, but I would also appreciate activities that address Grammar, Pronunciation, Fluency/Have her talk more naturally, quickly, and smoothly. I am looking for activities that get her talking and/or writing. Thank you in advance. She essentially knows all of the grammar and its rules we just need to practice them for consistency and to get rid of some incorrect grammar habits she has gotten into.
