I just finished reading Sketches on Legal Style by Mark Cooney, and I loved it. Lots of practical advice in a readable, engaging book. I recommend it.
From the publisher’s website:
Who says legal writing is a dull subject? This collection of lively, offbeat short pieces explores legal style like no book you’ve read before. But be warned: you just might learn something while you’re smiling. Through a colorful cast of characters, learn how legal writers can use plain language and careful syntax to produce clearer, stronger, and more persuasive documents.
Will legalese devotee Ebenezer Scribe change his ways after receiving visits from four clarity-minded ghosts?
Will Colonel Ketchup’s passive-voice phrasing obscure whodunit?
Will Editor Man defeat his most formidable foe yet: a dense block of statutory text containing, among other things, a 142-word sentence?
And much more . . .
