Law schools face increasing pressure to improve instruction in practice-oriented skills. One of the most important of these skills is legal writing. The existing literature on legal writing contains various rules and suggestions as to how legal writers can improve their writing skills. Yet it lacks an adequate theoretical account of the fundamental nature of good legal writing. As a result, legal writers are left without a solid conceptual framework to ground the individual rules and suggestions. This Article attempts to fill the theoretical void in the literature by offering a systematic analysis of what it is for a legal document to be well written. It starts by examining a foundational conceptual issue, which is what legal writers mean when they say that a legal document is well written.
