A more thorough explanation:

Definition: A causator is a person who promotes litigation or manages and litigates a cause for another.

Examples:

• John hired a causator to manage his lawsuit against his former employer.
• The causator was able to negotiate a settlement for the client.

The examples illustrate how a causator is someone who is hired to manage and litigate a legal case for another person. In the first example, John hires a causator to handle his lawsuit against his former employer. The causator will be responsible for managing the case, gathering evidence, and representing John in court. In the second example, the causator was able to negotiate a settlement for the client, which is one of the many tasks that a causator may be responsible for.
