Final answer:
A court-ordered sale of real property to satisfy an unpaid lien is known as a foreclosure. This legal process helps creditors recover debts by selling property used as collateral.
Step-by-step explanation:
When a court orders real property to be sold to satisfy an unpaid lien, the process is known as a foreclosure. This occurs when the owner of the property fails to pay a debt, and the creditor seeks to recover the money owed by forcing the sale of the property as collateral. The proceeds from the sale are then used to pay off the unpaid debt. A foreclosure is often associated with mortgages, where the lender will initiate the process if the borrower stops making payments on their home loan.
