An unsecured creditor is a creditor who is owed a debt by an individual or a company that is not secured by a security interest over the individual's or the company's property (for example, an employee is considered a special category or class of unsecured creditor).
A creditor may wish to submit a formal statement of what a creditor believes it is owed (known as a proof of debt) to establish its claim against the insolvent company or individual. For more information on proving for a debt, see Practice notes, Proofs of debt and Liquidation.
