Joinder Legal Meaning and Definition

Here is a simplified definition of the legal term Joinder.

Joinder (noun)

Joinder refers to the act of including additional parties (people or entities) or claims in a legal lawsuit. These included parties, who share the same claims or defenses, are called co-plaintiffs or co-defendants. There are two types of joinders:

  1. Permissive Joinder - Parties choose to join the lawsuit because they share common interests in the claim or relief.

  2. Compulsory Joinder - The court orders certain parties to join the lawsuit, and without their participation, a decision cannot be reached.
