Permissible
Permissible: Allowed or permitted, but not required. Rules often distinguish permissive language ("may") from mandatory language ("must" or "shall"). For example, the Federal Rules of Civil Procedure provide for permissive counterclaims (Rule 13(b)), permissive joinder of parties (Rule 20) and permissive intervention (Rule 24(b)), which a party may use but is not required to.
What permissible means
In practice, you will see permissible in pleadings, motions, orders and court rules. The definition above explains the general meaning. Even so, the meaning can shift with context. Therefore, always read it alongside the rule or document where it appears.
Where permissible comes up
The term is used across many kinds of cases. For example, you may see it in pleadings, motions and court orders. To see it in context, browse the motions and procedures library or the Learn the Law topics.
How to research the term
To research permissible, 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.
