A more thorough explanation:

Definition: Nonpersonal action refers to a legal action that is not directed towards a specific person, but rather towards a thing or property. It is a legal process of doing something or behavior that does not involve a personal interaction.

Example: A quiet-title action is an example of a nonpersonal action. It is a legal proceeding that establishes a person's title to a property by compelling the adverse claimant to establish a claim or be forever estopped from asserting it. This action is not directed towards a specific person, but rather towards the property in question.

Another example of a nonpersonal action is an action in rem, which is a legal action that determines the title to property and the rights of the parties, not merely among themselves, but also against all persons at any time claiming an interest in that property. This action is directed towards the property and not a specific person.

These examples illustrate how nonpersonal actions are legal proceedings that do not involve a personal interaction, but rather focus on the property or thing in question.
