A more thorough explanation:

Definition: Real action refers to a legal process of doing something or behavior. It can also mean a thing done or a civil or criminal judicial proceeding.

Examples:

• A lawsuit filed by a person against another person for the enforcement or protection of a right is an example of a real action.
• An action for unjust enrichment, in which the plaintiff must show that an enrichment was bestowed, that the enrichment caused an impoverishment, that there is no justification for the enrichment and impoverishment, and that the plaintiff has no other adequate remedy at law, including no remedy under an express or implied contract is another example of a real action.

These examples illustrate how real action involves a legal process of enforcing or protecting a right or seeking a remedy for an unjust enrichment or impoverishment.
