This “living e-book” by Margaret Hagan — summarizing her learnings of 3+ years of practice — is likely the best primer to be found on the topic of “legal design”:
This book sets forth an agenda for innovation in legal services, with practical, agile, and user-centered methods to make the legal system clearer, more efficient, more usable, and friendlier. It scopes out what it means for legal professionals to embrace a designer’s approach to solving problems.
Reading it as a designer, the first chapters make it apparent that this is at the same time an intro into “design” for lawyers (though repetition of the basics, with somebody else’s eyes, can never hurt), but overall this is just as inspiring a read for designers as it is for legal professionals.
