You probably want to know how to write well—or at least decently. (If you don’t, then I hope that you can hire somebody who can write.) An article by Michael Bess of Winston & Strawn should help. His article offers 12 tips for writing better. His advice includes the following:

      • Nail the introduction. Your introduction should state what the reader should do and why, and it should do so in one or two pages.
      • Drop unnecessary and case-specific details. A court does not care if the defendant in a case is Mr. Smith or Ms. Jones. Instead, when describing the facts of a case, state the legal significance of a party (e.g., landlord or the police).
      • Don’t recap legal standards unnecessarily. For instance, you don’t need two pages to state the standard for summary judgment.
      • Be discriminating in advancing arguments. You should not raise every conceivable argument. By doing so, you will water down your good arguments.
