What summons means

Put simply, summons is part of the working vocabulary of a civil case. The short definition above covers the usual meaning. Still, a specific rule, statute or contract can give it a narrower meaning. For that reason, check how it is used in your own documents.

Where summons comes up

For example, the term appears in these procedures:

  • Summons and Service of Process (Fed. R. Civ. P. 4): the formal way a defendant is notified of a lawsuit. The plaintiff must serve the summons together with a copy of the complaint (Rule 4(c)(1)).

How to research the term

To research summons, 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.
