What memorandum means

In short, memorandum is a term you will meet in court papers, rules and legal research. The definition above gives its usual meaning in American civil practice. However, the exact meaning can depend on the rule, statute or court decision that uses it. So it helps to read the term in context.

Where memorandum comes up

For example, the term appears in these procedures:

  • Motions: Form and Requirements (Fed. R. Civ. P. 7(b)): the general rules every written motion must follow.
  • Opposition (to a Motion) (Fed. R. Civ. P. 6(c)(2), 56(c), 56(e); local rules): a party's written argument asking the court to deny another party's motion, usually with a memorandum of points and authorities and any supporting declarations or evidence.

How to research the term

To research memorandum, begin with the rule, statute or contract where the word is used. Each one can give it a slightly different meaning. Then compare that text with how courts in your area have applied it. Also check the local rules of your court, since they can add requirements. If your case is in state court, the state rules control. So start with our state procedures guide to find them. In the end, always confirm that the source you rely on is current.
