What is A sum of money placed on a person property's or income?

A sum of money placed on a person's property or income is typically referred to as a lien. A lien is a legal right or interest that a lender or creditor has in the borrower's property, granted until the debt obligation is satisfied. It serves as a security for the repayment of a loan, allowing the creditor to claim the property if the borrower defaults. In essence, it ensures that the lender has a legal claim to the asset as collateral for the debt.
