one of the best classes I ever took was a drafting class taught by an old professor who was actually a very successful lawyer for years before moving to academia.... in stark contrast to probably 50-75% of law professors who went from law school to clerking for a circuit court judge to back to academia or some other similar not real life type of "career" before they entered fake life
he hated belt and suspenders drafting and 200 year old words
he hated forms because the majority of the time a firm hadn't updated it in years and 1/2 of it was useless and not needed
you should know exactly why you used every word you used and you should write to prevent confusion (of your client, of the court and of any opposing party)
you never want your client to say: "I didn't know I couldn't do that" or "I didn't know I was supposed to do XYZ"
PS: cards on the table I almost used “WHEREAS” twice in my post.
