Do Not Use “and/or” in Legal Writing, by Ted Tjaden, Slaw Canada’s online legal writing magazine
If there was any question in my mind about whether using “and/or” is good legal writing, it is resolved. After reading Mr. Tjaden’s post, supported by detailed, exhaustive research, you too may become a believer. -CCE
I remain surprised at the number of intelligent, articulate, and well-read legal professionals who still use ‘and/or’ in legal writing.
I am therefore creating this post to document a fairly complete list of authorities that support what I think is the better (if not obvious) view: never use ‘and/or’ in legal writing (or any writing). And yes, I said ‘never.’
