Which term would best describe an officer's action to enforce a court's order?

The term that best describes an officer's action to enforce a court's order is "Execution." In the context of civil process, execution refers to the implementation of a court's judgment or order. This can involve taking actions such as seizing property, garnishing wages, or other measures to ensure compliance with what the court has mandated. When an officer executes a court order, they are actively carrying out the directive provided by the court to ensure that justice is upheld and that the rights granted by the court are enforced.

Sequestration typically refers to the act of taking possession of property until a dispute is resolved, rather than enforcing a pre-existing court order. Service pertains to the delivery of legal documents to parties involved in a case, ensuring they are informed of actions being taken or required of them, but does not involve enforcement. Submission generally refers to the act of presenting a case or evidence to the court and is not associated with enforcing court orders. Understanding these distinctions highlights why "Execution" is the most appropriate term in this context.
