Final answer:
A court order instructing an official to sell property in order to pay a judgment is called a writ of execution.
Step-by-step explanation:
The court order that instructs an official, such as a sheriff, to sell property in order to pay a judgment is called a writ of execution.
A writ of execution is typically issued after a judgment has been entered in favor of a creditor or plaintiff. It allows the court to enforce the judgment by seizing and selling the debtor's property to satisfy the debt.
For example, if a person owes money to a creditor and fails to pay, the creditor can take legal action by obtaining a judgment and then requesting a writ of execution to enforce the judgment and collect the debt.
